Published: March 2021

This study aims to identifying the impact of big data analysis on the accounting Profession in Jordanian business environment. To achieve the study objectives researcher distributed a questionnaire to (147) out of certified public accounts, financial analysis and experts in big data analysis in the kingdom of Jordan. (108) questionnaires were returned. The response rate was (51.7%) of the population. In addition, the study sought to verify the hypothesis of the study. In order to analysis the data, the researcher used means, standard deviation and T-test. The result of the study revealed that the big data analysis have a significant role on the accounting roles and improve the quality of accounting characteristics in Jordan with an overall means (4.52). Based on the results of hypotheses, rejected the null basic hypothesis of the study, and the two null sub-hypotheses were rejected. In light of findings the researcher gave a number of recommendations:1- The necessity of teaching big data and business analysis in the accounting education curricula at the undergraduate level to enhance students' knowledge of the importance of that data.2- Holding workshops and training courses for researchers and academics to knowing them the importance of analyzing big data and how to process, store, manage and invest it in the accounting and financial field.
Biblical Veganism: An Examination of 1 Timothy 4:1–8
Authors: Newall Marcello
Published: March 2021

1 Timothy 4:1–8 is often used as a proof text against veganism; this is especially true among certain fundamentalist Christian groups and conspiracy theorists. This article argues that a closer look at its linguistic, historical, and theological context reveals that Paul is in reality seeking to uphold the goodness of creation, as described in the first chapters of Genesis, against the dualistic proto-Gnostic creation story that saw the material world as evil. In this sense, 1 Timothy 4:1–8 appears to be a point-by-point rebuttal of the proto-Gnostic view of creation, which is contrasted with the account in Genesis. In particular, the apostle is denouncing a harsh asceticism, and food restriction/deprivation, described as “bodily exercise,” which by severely mortifying the body sought deliverance from the material world. The article goes on to analyze ancient forms of asceticism as well as dietary patterns in the ancient Mediterranean in order to show how contemporary veganism differs sharply from the kind of mortification that is being condemned. 1 Timothy 4:1–8 highlights how food, generally understood, and creation should be received with thanksgiving as they are both gifts from God, which were pronounced good. Furthermore, 1 Timothy underlines that true Christian holiness does not consist in the harsh mortification of the body but in an inner holiness based on love and faith in the incarnation, death, and resurrection of Christ. Ultimately, veganism, far from being anti-Christian, as God’s original ideal, can be seen as a sign of hope pointing to the coming of the Kingdom of God and the restoration of creation beyond all violence, suffering, and death.
Corporate Green Bond and Stock Price Reaction
Authors: Cioli Valentina , Andrea Colonna Lorenzo , Giannozzi Alessandro , Roggi Oliviero
Published: March 2021

The aim of this paper is to investigate the investors’ reaction to environmental actions taken by companies such as the issues of “green bond”. We conduct an event study around the announcement of green bond issuances for all publicly traded companies in the World in the period 2013-2019 (the largest period in literature on this field). Using CARs, we investigate the stock price behavior to green bond issues for 414 listed companies and we demonstrated significant stock price increases around the announcement date of first-time green bond issues. For second issues, the positive stock price reaction to eco-friendly initiatives decreases while it completely disappears for the subsequent issues. From the management perspective, green bond issue seems an eco-friendly action with decreasing marginal benefits, because after the first issue, the market is already aware about the firm’s commitment to green projects.

Published: March 2021

Objetivo: Este trabalho teve por finalidade identificar quais são as principais barreiras que dificultam a aplicação da sustentabilidade ambiental nas atividades logísticas da cadeia da construção civil imobiliária da cidade de Curitiba/PR. Metodologia: Foi realizada uma análise de conteúdo na literatura que permitiu a elaboração de um questionário em que foram investigadas as barreiras junto a especialistas do setor na cidade de Curitiba/PR. Relevância: Observa-se que a construção civil tem um grande impacto econômico e social e é estimada uma grande tendência de crescimento no Brasil, especialmente com relação à construção imobiliária, devido às demandas de déficit habitacional. Além disso, a construção civil é conhecida por causar um significativo impacto ambiental negativo em virtude das suas atividades produtivas e logísticas, entretanto, considerando tais aspectos existem alternativas como a Logística Reversa, a Logística Verde e a Gestão Verde da Cadeia de Suprimentos (GSCM), mas que costumam não ser aplicadas por barreiras que as inibem. Resultados: Após aplicação da metodologia proposta, verificou-se que as principais barreiras à sustentabilidade ambiental são a falta de conhecimento sobre sustentabilidade, carência de indicadores de gestão e a ausência de integração entre os membros da cadeia de suprimentos.
The relationship between the experience of negative feelings and quality of life and the socio-demographical factors of patients treated for spinal discopathy of the lumbar spine
Authors: Girzelska Joanna , Chomicki Leszek
Published: March 2021

Most of the pathological changes in the spine begin with the physiological loss of intervertebral disc function. Discopathy of the lumbar spine leads to a significant deterioration in the quality of life, which is why the therapeutic team strives is to improve patients quality of life through actions aimed at reducing spinal dysfunction to an extent that allows for human functioning. The research aim was to determine the quality of life of patients who had been treated as a result of discopathy of the lumbar spine and to establish the relationship between the experience of negative feelings and a subjective assessment of the quality of life with factors resulting frompatient socio-demographics.

The study included 110 patients treated for lumbar discopathy. A diagnostic survey method was employed as a research technique, with the use of a proprietary survey questionnaire. Statistic analysis of the results was performedusing the statistical package PQStat v1.6.6.

Subjective evaluation of patients quality of life in 66 persons (60%) was at an average level, only 6 (5.45%) respondents rated the quality of their lives as being higher. Those living in towns of up to 50,000 residents rated their quality of life higher (6.21), with the lowest level being reported by those living in the countryside (4.95). Age did not influence significantly the quality of life, but older people most often experienced pain (p=0.4). Analysis of variance did not show statistically significant differences between marital status and respondent quality of life (p = 0.53) but did show significant differences between education levels and the incidence of negative feelings such as fear, anxiety or depression.

Socio-demographic variables: such as gender, age and marital status do not significantly differentiate the quality of life of the respondents. There is a relationship between experiencing negative feelings and educational levels. The lower the education level obtained, the more often negative feelings are experienced. The experiencing of negative feelings and disease duration are variables that reduce the quality of life of respondents.
OCEAN EDUCATION • Virtual and Remote—Hands-On Undergraduate Research in Plankton Ecology During the 2020 Pandemic: COVID-19 Can’t Stop This!
Authors:   Graduate School of Oceanography, University of Rhode Island, Marrec Pierre , Miller Andria , Maranda Lucie , Menden-Deuer Susanne
Published: March 2021

The pandemic has had innumerable impacts on the oceanographic community, including on summer research internship programs that expose undergraduates to diverse career paths in oceanography while immersed in an active laboratory. For many students, these internships are formative in their career choices. The Summer Undergraduate Research Fellowship in Oceanography (SURFO) at the University of Rhode Island’s Graduate School of Oceanography is one of the Research Experiences for Undergraduates (REU) programs that proceeded remotely during the summer of 2020. Here, we highlight one project that, although remote, maintained a hands-on research experience focused on quantitative skill building. The pandemic forced the REU advisors to identify key learning goals and ensure their safe delivery, given the circumstances. Although all participants agreed that in-person instruction would have been preferable, we were pleased that we did not let a virus halt essential oceanographic research training.

Food additives: Risk analysis and legislation
Authors: Stanković Ivan , Zrnić-Ćirić Milica
Published: March 2021

Food additive is any substance not normally consumed as a food, the intentional addition of which to food for a technological purpose results in it or its by-products becoming a component of such foods. The use of each new additive is preceded by a risk analysis consisting of three interrelated components: risk assessment, risk management and risk communication. At the international level in the Codex Alimentarius system, risk assessment is performed by the Joint (FAO/WHO) Expert Committee on Food Additives (JECFA) and risk management by Codex Alimentarius Commission (CAC) that, based on the results of the risk assessment, prepares international standards and recommendations that Member States incorporate into national regulations. At the level of the European Union (EU), risk assessment is performed by the European Food Safety Authority (EFSA) as a basis for risk management by the European Commission (EC) that prepares food additive legislation, and member states authorities responsible for official control of additives on the market. Risk communication takes place between all stakeholders including academia, food producers and consumers. The regulation on additives in the Republic of Serbia is fully harmonized with the EU legislation in this area.
Assessment of hot-melt coating methods for multiparticulate substrates: Mortar-coating vs. pan-coating
Authors: Ignjatović Jelisaveta , Đuriš Jelena , Đuriš Mihal , Bočarski Teodora , Vasilijević Vanja , Aleksić Ivana , Cvijić Sandra
Published: March 2021

Hot-melt coating (HMC) is an alternative, solvent-free coating method generally used to modify substrate release rate and/or mask its unpleasant taste. The aim of this study was to assess two HMC methods (pan-coating and mortar-coating) by assaying functional properties of the coated material. The selected substrates included highly soluble sodium chloride (model substance) and caffeine (bitter drug), and the coating agent was glycerol distearate without/with the addition of liquid paraffin. Experiments with sodium chloride revealed that pan-coating yielded particles of more regular shape, while mortar-coating yielded samples of more uniform coating layer. The flowability of the coated material depended on the particle size. Sustained sodium chloride release was achieved for all mortar-coated and some pan-coated samples. The analysis of the results indicated mortar-coating as a preferable HMC method for caffeine coating. The resulting caffeine yield in the coated samples was high (99%), the material showed satisfactory mechanical properties and drug release from the coated particles was sustained. Overall, the obtained results suggest that both pan-and mortar-coating can be used to sustain the release of drugs with unpleasant taste, but mortar-coating can be considered as a more simple and practical method that can be potentially used in compounding pharmacies.
Spectrophotometric determination of morin in strawberries and their antioxidant activity
Authors: Pavun Leposava , Janošević-Ležaić Aleksandra , Uskoković-Marković Snežana
Published: March 2021

Morin is one of the flavonoids with intensive antioxidant activity. With the aim to use its benefits on human health, there is an increasing trend to pay attention to its content in food or supplements. The simplicity and low cost of spectrophotometric determination based on the formation of a morin complex with Zn 2+ ion (stoichiometric ratio 1 : 1), at pH 7.98 and 392 nm, give it an advantage over other methods that can be used for morin quantification. The concentration range over which the response was linear was 0.151-4.533 mg L-1. The limit of detection (LOD) and the limit of quantification (LOQ) were 0.030 mg L-1 and 0.091 mg L-1 , respectively. The developed method was successfully applied for the determination of the morin content in strawberries. Additionally, the antioxidative abilities of strawberry extracts and morin, determined by DPPH and FRAP tests, were compared and discussed.
Existing outside of the law: Kafka's philosophy of law
Authors: Prole Dragan
Published: March 2021

Variations of the idea that regardless of how bad things are in the world of man, man's tendency to protect himself by creating illusionary presentations about it is worse, exist in many places in Kafka's works. If the origin of the leading among the fatal illusions of the present is connected to the need for security, safe haven, protection - the same need that laid the foundation for the necessity to introduce laws and develop a legal system - then important pages of Kafka's literature can be read in light of a type of negative anthropology. Its premises seem as if to testify to the betrayed human urge to protect every individual via courts and laws. The author pays special attention to the question of what it means to be outside of the law, stressing that the man from the country who remains before the law metaphorically represents Jewish refugees from Galicia who remained before the gates of Prague in 1914.
The formulation of the idea of justice in the "poem on justice"
Authors: Kaluđerović Željko
Published: March 2021

As one of the most important principles of forming of social relations, Hesiod emphasizes the principle of justice. He places the idea of justice into the very core of life, because it is in this idea that he finds the root out of which a different world and a better one is to be born. Hesiod's idea of justice is manifested as a need for strengthening the relation of equivalence when it is stable and adequate, and for its establishing in case it is disbalanced and inadequate. The presence of justice at all levels, from the highest metaphysical one, all the way to the relations within the practical sphere, shows that it can be considered as a mighty deity, as a cosmic principle, but also as a legitimate basis of comprehensive human action. In Hesiod's writings it is finally suggested that there is a difference between the order of causality of irrational nature and the order of duties of morality, actually between bia on one hand and nomos and dike on the other. Believing that living beings can not disturb the order of bia, while humans can disturb the order of dike, Hesiod postulates the difference which will be crucial for the later philosophical consideration of the field of praxis.
Necessity of closer international cooperation of various institutions in fighting against insurance fraud
Authors: Petrović Miloš
Published: March 2021

In this paper, the author analyses a few examples of fraud in life and accident insurance. The cases that are the subject of this Article can be classified as "heavy frauds" according to the seriousness of the crime committed and as "external" according to the source type. The course and epilogue of the trials show how important it is to have the closest possible coordination between the judicial, police and insurance institutions and that the character of insurance frauds is becoming increasingly international, requiring stronger cross-border inter-institutional cooperation. Also, experts from a growing number of disciplines (from medicine, through mechanical engineering to technological sciences) do have a particularly notable role in discovering false insurance claims. Their expertise findings can make a decisive contribution to clarifying the circumstances of each and every case. The examples presented in this Article illustrate that closer cooperation between all the named participants and the use of advanced methods and technologies are the indispensable tool of a good and a more efficient fight against the insurance fraud.
Meeting liberalization of motor liability insurance premium in Serbia
Authors: Doganjić Jelena , Ristić Živorad
Published: March 2021

Free definition of motor third party liability insurance tariffs leads to individual statement of premiums in agreement with the degree of risk the insured are exposed to i.e. their behaviour in the previous period. Using the experience of neighbouring countries, which have introduced a system of liberalization of motor third party liability insurance premiums, with prior quality preparation, Serbia could establish the liberalization of motor third party liability insurance premiums which could significantly contribute to insurance market advancement. This can also affect the behaviour of drivers, whereby we would raise the level of traffic safety and reduce the consequences and damages caused by traffic accidents.
Sentencing and enforcement of the prison sentence served in the premises where the convicted person resides: The so-called house arrest
Authors: Drakić Dragiša , Milić Ivan
Published: March 2021

The rule that convicted persons serve their sentences exclusively in prisons has not been valid in the Republic of Serbia for a long time. Prison sentences may also be executed in the premises where the convicted person resides. Such a solution is introduced by the 2009 Law on Amendments and Supplements to the Criminal Code. The Criminal Code does not prescribe the punishment of a prison sentence served in the premises where the convicted person resides as a special punishment. Instead, the offender is sentenced to imprisonment, which is then executed in the premises where he lives. In criminal proceedings, the court is obliged to individualize the criminal sanction in a way that takes into account objective and subjective circumstances - the circumstances relating to the committed crime and its perpetrator. There are such perpetrators who it is necessary to sentence to prison, but who should not be sent to a penal institution. The prison sentence may also be served in premises where they reside (with or without electronic surveillance). Although, in a legally-binding sentence, the accused is sentenced to imprisonment in a penal institution, this does not necessarily mean that he will be placed into a penal institution to serve his sentence. The amendments and supplements of the Criminal Code leave an "opportunity" for the convict to serve his sentence in the premises where he resides, if the prescribed conditions are met. This is only a possibility which may be decided on by the judge in charge of executing criminal sanctions. If it is decided that the convicted person shall serve his sentence in the premises where he resides, the next step is the execution of the sentence. Not all convicted persons who are serving their sentence in this way are in the same legal position, as there is individualization in the process of executing a sentence as well. This difference is apparent, above all, in the amount of time that a convict is allowed to spend outside of the premises in which he resides. The focus of the authors' attention is precisely the punishment of imprisonment served in the premises where the convict resides (the so-called house arrest). The authors deal with material aspects and aspects of execution of the sentence. This paper focuses, among other matters, on the conditions for sentencing, models of execution of the sentence and the legal position of the convicted person while serving his sentence.
Physical Restraint, Seclusion, and Time-Out Rooms in Canadian Schools: Analysis of a Policy Patchwork
Authors: Bartlett Nadine Alice , Floyd Ellis Taylor
Published: March 2021

The intended purpose of physical restraint, seclusion, and time-out rooms in schools is to intervene in a crisis when the behaviour of a student poses an immediate or imminent, and significant threat to physical safety. While the use of physical restraint, seclusion, and time-out rooms is intended to provide protection from immediate physical harm, there is increasing concern that these practices are being used more broadly and that individuals with disabilities are disproportionately subjected to their use. In spite of the importance of this issue, there is a dearth of research analyzing the policy landscape of physical restraint, seclusion, and time-out rooms in Canadian schools. In order to explore this issue, a comparative analysis of publicly available provincial and territorial education documents was conducted. The analysis revealed that in many Canadian provinces and territories, policies and accountability structures on the use of physical restraint, seclusion, and time-out rooms in schools are inconsistent or non-existent. Further, the terminology used to describe seclusion is variable and often conflated with time out, and the conditions under which such practices may be used in some instances are subjective, which may contribute to a broad interpretation of what is deemed acceptable practices in schools. This analysis draws attention to the need for the development of clearly articulated provincial and territorial standards for the use of physical restraint, seclusion, and time out, as well as the need for regulatory and enforcement mechanisms at the school, division, and ministry levels in order to ensure the emotional and physical well-being of all.
Cell Phones, Student Rights, and School Safety: Finding the Right Balance
Authors: Smale William T. , Hutcheson Ryan , Russo Charles J.
Published: March 2021

Despite the potential instructional benefits of integrating devices such as cell phones into schools and classrooms, research reveals that their improper use can negatively impact student behaviour, learning, and well-being. This paper reviews the literature and litigation on cell phone use in schools due to controversies over cheating, cyberbullying, sexting, and searches of student cell phones. Recent studies suggested that the presence of cell phones and related technologies in classrooms could detract from students’ academic performances while contributing to higher rates of academic dishonesty and cyberbullying. The growing prevalence of cyberbullying is especially concerning because it can have severely negative, even tragic, effects on student mental health and safety. However, given the relatively discreet nature of cell phone use, regulations about their use can be difficult to enforce. After reviewing literature and litigation on the potential risks associated with inappropriate cell phone use in schools, this paper offers suggestions for educators to consider when devising or revising policies balancing students’ individual rights with their safety and well-being before ending with a brief conclusion.
International Education and the Internationalization of Public Schooling in Canada: Approaches and Conceptualizations
Authors: Elnagar Abdelhady , Young Jon
Published: March 2021

While there is now an extensive literature related to the internationalization of post-secondary education in Canada, developments within K-12 public schooling have received much less attention. This article explores recent developments in international education in Canadian public school systems, with specific attention to developments in Manitoba. In doing so it argues that these developments incorporate three distinct policy interests – trade, immigration and education – resulting in strong federal influences on provincial education policies and practices. The article examines two major international education initiatives: the recruitment of international students; and, the establishment of affiliate school agreements overseas. It argues that these recent developments reflect a particular notion of “the internationalization of public schooling” where a historical notion of “international education” as a learning-focused concept has been supplanted by an economic and market-driven notion that has trade and immigration considerations as its primary interests.

Published: March 2021

Obesity is a global problem and numbers are rising at a fast pace in developing countries and it becomes a major public health concern. Economic costs associated with obesity are high and increasing with the rate of obesity. Obesity is a state of body fat being accumulated in excess, and it is well known that many diseases including metabolic disorders, such as diabetes and hyperlipemia and diseases in circulatory organs Such as hypertension and ischemic cardiac diseases tend to follow obesity. The fat contained in meals is one of the nutrients most profoundly related to the accumulation of body fat, but the excessive ingestion of fat may result in obesity. However, fat has intrinsic taste, and meals of extremely reduced-fat are often insufficient to give Satisfaction. Further, when deep-fried food or fried food is made, edible oil is indispensable as a heating medium. The so-called fat substitutes were developed in the early 2000s for resolving such a situation. However, none of them are fully satisfactory in Safety, physical properties, cooking properties and flavor. This review will discuss the dietary fats that were developed for different food applications which are claimed as healthy oils with lower calorie intake than classical triglycerides oils which have a caloric content of average of 9 cal/gm and recommendations for optimum healthier and dietary for obesity and diabetic control and lower calories food.
Constructivist Teachers Beliefs, Instructional Practices and Students’ Mathematics Performance
Authors: Balanlay Mary Cris Danes
Published: March 2021

This study determined the role of teachers’ constructivist beliefs in the teaching and learning mathematics and the use of instructional practices in the mathematics performance of Grade 7 secondary students in the Pacific Towns of Northern Samar for the school year 2016-2017. This study utilized the descriptive-correlational research design.

The demographic profile of teachers in mathematics such as constructivist beliefs, constructivist instructional practices and performance of students was described as it exists at the present time. Multiple regression analysis was used to determine the relationship between the beliefs in mathematics and students’ mathematics performance. Similarly, statistical analysis was used to determine the relationship between instructional practices and mathematics performance of the students.

The findings showed that more than 50% of the mathematics’ teachers are aged less than 30 suggesting that most of the teachers are neophyte in the teaching career. As to educational attainment, most of the respondents are enrolled in master’s program. Only one-third have already completed master’s degree. In terms of relevant trainings, almost a half of the respondents have attended one to two trainings.

Most of the teachers believe that teaching should involve real world connections. Teachers believe that they should create real-world environments that employ the context in which learning is relevant. Beliefs about emphasizing prior knowledge were also manifested by the teacher-respondents. Highly demonstrated beliefs include encouraging the use of multiple modes of representation to facilitate easy understanding and recall and the learner's previous knowledge constructions, beliefs and attitudes are considered in the knowledge construction process. In terms of social interaction beliefs, teachers manifested support for collaborative construction of knowledge through social negotiation.

Result of the test conducted in mathematics by the researcher showed that more than half of the students got fair performance. Only one performed satisfactorily. Beliefs about emphasizing prior knowledge and beliefs in social interaction significantly predicted mathematics performance of students. Real world connection did not significantly predict mathematics performance.

Respondents’ constructivist instructional practices did not offer a significant role in developing the mathematics ability of the students. Teachers did not play an active role in assimilating knowledge into students’ existing mental framework and reconstructing new knowledge.
Air Quality Assessment of Port Harcourt Urban Slums and Health Implications

Water electrolysis is promising for industrial hydrogen production to achieve a sustainable and green hydrogen economy, but the high cost of the technology limits its market share. Developing efficient yet economic electrocatalysts is crucial to decrease the cost of electricity and electrolytic cell. Meanwhile, electrolysis in seawater electrolyte can further reduce feedstock cost. Here, a type of electrocatalyst is synthesized, where trace precious metals are strongly anchored on a corrosion‐resistive matrix. As an example, the produced Pt/Ni‐Mo electrocatalyst only needs an overpotential of 113 mV to reach an ultrahigh current density of 2000 mA cm−2 in the saline‐alkaline electrolyte, demonstrating the best performance reported thus far. It shows high activity and long durability in various electrolytes and under harsh conditions, including strong alkaline and simulated seawater electrolytes, and under elevated temperatures up to 80 °C. This electrocatalyst is produced on a large scale at a low cost and shows good performance in a commercial membrane electrode assembly stack, demonstrating its feasibility for practical water electrolysis.

Polymeric g‐C3N4 is a promising visible‐light‐responsive photocatalyst; however, the fast recombination of charge carriers and moderate oxidation ability remarkably restrict its photocatalytic oxidation efficiency towards organic pollutants. To overcome these drawbacks, a self‐modification strategy of one‐step formaldehyde‐assisted thermal polycondensation of molten urea to prepare carbon‐deficient and oxygen‐doped g‐C3N4 (VC‐OCN) is developed, and the carbon vacancy concentration is well‐controlled by changing formaldehyde dosage. The VC‐OCN catalysts exhibit interesting carbon vacancy concentration‐dependent photocatalytic removal efficiency to p‐nitrophenol (PNP) and atrazine (ATN), in which VC‐OCN15 with appropriate carbon vacancy concentration displays significantly higher pollutant removal efficiency than bulk g‐C3N4. The apparent first‐order rate constant of VC‐OCN15 for PNP and ATN removal is 4.4 and 5.2 times higher than that of bulk g‐C3N4. A combination of the experimental results and theoretic calculations confirm that the synergetic effect of carbon vacancies and oxygen doping sites can not only delay the recombination of charge carriers but also facilitate adsorption of oxygen molecules on the carbon vacancies, which leads to the generation of plentiful active oxygen species including not only superoxide anion radicals but also indirectly formed hydroxyl radicals and singlet oxygen. These active oxygen species play a dominant role in the removal of target pollutants.

Although strain underpins the behavior of many transition‐oxide‐based magnetic nanomaterials, it is elusive to quantify. Since the formation of orbital molecules is sensitive to strain, a metal–insulator transition should be a window into nanocrystallite strain. Using three sizes of differently strained Fe3O4 polycrystalline nanorods, the impact of strain on the Verwey transition and the associated formation and dissolution processes of quasiparticle trimerons is tracked. In 40 and 50 nm long nanorods, increasing isotropic strain results in Verwey transitions going from TV ≈ 60 K to 20 K. By contrast, 700 nm long nanorods with uniaxial strain along the (110) direction have TV ≈ 150 K—the highest value reported thus far. A metal–insulator transition, like TV in Fe3O4, can be used to determine the effective strain within nanocrystallites, thus providing new insights into nanoparticle properties and nanomagnetism.

Published: March 2021

Light‐emitting diode (LED) lighting delivers better performance and reliability, and substantially lowers the total cost of ownership compared with conventional lighting. The most common white LED is generally produced using a blue LED chip and phosphor combination to generate white light. This type of phosphor‐converted white LED can be a great alternative to the more expensive 3 chip RGB (red, green, blue) LED. Herein, cellulose nanocrystals, a wood‐derived biopolymer, are used with phosphor to improve the uniformity of correlated color temperature (CCT) and luminous flux from the white LED. These nanocrystals can scatter light strongly and for an optimized concentration of nanocrystals, it is found to increase the luminous flux of the white LED by over 30% compared with the reference sample without any nanocrystal. The CCT uniformity is also improved from 173.45 K for the reference sample to 59 K for the optimized sample. The chromaticity coordinates are also studied and found to be shifting toward lower correlated color temperatures with increasing cellulose concentrations. Combining these results with low cost, wide availability, and environmental impact, cellulose nanocrystals can play an important role in the future generation of white LEDs.

Despite the benign nature of monoclonal gammopathy of undetermined significance (MGUS), mounting data are associating MGUS with the development of organ dysfunction, specifically monoclonal gammopathy of renal significance (MGRS) and monoclonal gammopathy of neurological significance (MGNS), which could be associated with substantial morbidity. Emerging evidence suggests that patients with MGRS and MGNS could benefit from treatments used for myeloma, Waldenström macroglobulinemia, or chronic lymphocytic leukemia, depending on the underlying pathology. However, the treatment of MGRS and MGNS is not standardized, and potentially effective therapies might not be reimbursed because these conditions do not formally meet the criteria for malignant processes. The present review aims at establishing standards for the evaluation and management of MGRS and MGNS, which can facilitate the diagnosis of and provide therapeutic options for treating practitioners and patients affected by these conditions. The careful design and execution of clinical trials for patients with MGRS and MGNS are positively encouraged.

Published: March 2021

Medication adherence is a medical and societal issue worldwide, with approximately half of patients failing to adhere to prescribed treatments. The goal of this Minireview is to examine how recent work on microfluidics for point‐of‐care diagnostics may be used to enhance adherence to medication. It specifically focuses on capillary microfluidics since these devices are self‐powered, easy to use, and well established for diagnostics and drug monitoring. Considering that an improvement in medication adherence can have a much larger effect than the development of new medical treatments, it is long overdue for the research communities working in chemistry, biology, pharmacology, and material sciences to consider developing technologies to enhance medication adherence. For these reasons, this Minireview is not meant to be exhaustive but rather to provide a quick starting point for researchers interested in joining this complex but intriguing and exciting field of research.

We report that user‐defined DNA nanostructures, such as two‐dimensional (2D) origamis and nanogrids, undergo a rapid higher‐order folding transition, referred to as supra‐folding, into three‐dimensional (3D) compact structures (origamis) or well‐defined μm‐long ribbons (nanogrids), when they adsorb on a soft cationic substrate prepared by layer‐by‐layer deposition of polyelectrolytes. Once supra‐folded, origamis can be switched back on the surface into their 2D original shape through addition of heparin, a highly charged anionic polyelectrolyte known as an efficient competitor of DNA‐polyelectrolyte complexation. Orthogonal to DNA base‐pairing principles, this reversible structural reconfiguration is also versatile; we show in particular that 1) it is compatible with various origami shapes, 2) it perfectly preserves fine structural details as well as site‐specific functionality, and 3) it can be applied to dynamically address the spatial distribution of origami‐tethered proteins.

In recent years, polymeric nanoparticles (NPs) have become increasingly popular for in vitro and in vivo bioimaging because of their excellent versatility and exceptional optical properties. Following a brief introduction on fluorescence and photoacoustic imaging, as well as the merits of using polymeric NPs over other types of fluorescent probes, this Minireview gives a concise summary of key advances made in recent years (2017–2020) in the use of polymeric NPs for fluorescence and photoacoustic imaging. A particular focus is placed on various strategies used for enhanced bioimaging applications, including polymeric NPs that encapsulate near‐infrared dyes, aggregation‐induced‐emission fluorogens, cationic dyes doped with bulky hydrophobic counterions, and semiconducting polymers. Next, the current limitations in some of these polymeric NP systems are summarized and potential solutions offered to overcome them. Finally, some critical considerations in regard to the design of polymeric NPs are given for future bioimaging and sensing applications.

A facile synthesis is reported of two‐dimensional (2D) bimetallic (Fe/Co=1:2) metal–organic frameworks (MOF, ca. 2.2 nm thick) via simple stirring of the reaction mixture of Fe/Co salts and 1,4‐benzene dicarboxylic acid (1,4‐BDC) in the presence of triethylamine and water at room temperature. The mechanism of the 2D, rather than bulk, MOF was revealed by studying the role of each component in the reaction mixture. It was found that these 2D MOF‐Fe/Co(1:2) exhibited excellent electrocatalytic activity for the oxygen evolution reaction (OER) under basic conditions. The electrocatalytic mechanism was disclosed via both experimental results and density functional theory (DFT) calculation. The 2D morphology and co‐doping of Fe/Co contributed to the superior OER performance of the 2D MOF‐Fe/Co(1:2). The simple and efficient synthetic method is suitable for the mass production and future commercialization of functional 2D MOF with low cost and high yield.
