Published: June 2020

This research examines and proves the contribution of real estate activities and financial and insurance industry activities to the formation of Indonesia's Gross Domestic Product in 2000-2017. The issue that will be discussed is about the variables that influenced the formation of Indonesia's Gross Domestic Product in 2000-2017. The purpose of this study is to prove the influence of the contribution of real estate activities and financial and insurance industry activities to the formation of Gross Domestic Products in Indonesia. To analyze and prove the hypothesis an empirical test was carried out in the form of Q Square prediction with Smart PLS 3.1 on the magnitude of the influence of the activity sub-sector. The method used in data collection is a combination of secondary data derived from Asia Development Bank data. The method used to analyze data is the time series data method. The results showed that Real Estate Activities is an independent variable that does not have a positive and significant effect on the formation of a total Gross Domestic Product. It can be seen from the statistical t value of 1,800> from the t table value of 1,964 and this can be proven by the original sample value of 0.073 and the significance of 0.073> 0.05 which means that Real Estate Activities has no positive effect and significant to the formation of total Gross Domestic Product. Variable Financial and Insurance Activities are independent variables also do not have a positive and significant effect on the formation of total Gross Domestic Product. This can be seen from the statistical t value of 0.401> from the t table value of 1.964 and this can be proven by the original sample value of 0.689 and no significance of 0.005 = 0.05 which means that Financial and Insurance Activities have no effect positive and significant towards the formation of total Gross Domestic Product.
Labour Productivity in Different Segments of Aircraft Industry
Authors: Sobolev Leonid
Published: June 2020

This article is devoted to the problem of labor productivity (LP) in various segments of the global aircraft industry over the past decade. Intense competition forces aircraft manufacturers to pursue a policy of saving resources (primarily, workforce) at the all stages of the life cycle of aircraft and to introduce innovative technologies, automation, and robots. In assessing the relative growth of LP, the inflation (relative to the base 2009) and the purchasing power parity (PPP) of national currencies relative to the dollar are taken into account. The analysis showed that the LP is different for aircraft market segments and depends on development of market relations in the countries-manufacturers. The author believes that the main difficulty to the LP growth in countries with developing markets are monopolism, weak management, and insufficient skills of engineers, marketers, and workers.

Published: June 2020

There is a subsequent work from the previous studies on the relationship between firm-specific attributes and firm leverage. Then, during the last decade, international studies started to extend this field by scrutinizing how the firm leverage influences firm performance. However, much of the discussion from previous studies have not systematically investigated the simultaneously of the cause-effect framework on the impact of firm-specific attributes on firm financial performance through firm leverage which acts as a mediator variable. In short, it is reasonable to examine the mediating effects in which whether firm leverage may mediate or indirectly influence the relationship between firm-specific attributes and firm financial performance, particularly, from the perspective of Malaysian Shariah Compliant companies. The main motivation for this research is to contribute to corporate finance literature and how firms tend to choose their financing structure from the perspective of the capital structure theories. We obtained data of 398 Malaysian Shariah compliant companies from the Bursa Malaysia stock exchange with a total number of samples of 7414 for the sample data period from 2000 to 2018. We find that there are three relationships that categorize as competitive mediation which is the relationships between the asset tangibility (AT), growth opportunities (GRW), firm size (FS) and firm financial performance. While, non-debt tax shield (NDTS) is categorized as a complementary mediation. We use the PLS-SEM approach in SmartPLS software 3.0 M3 to develop a set of mediation model from the perspective of capital structure theory for the Malaysian Shariah compliant companies.

Published: June 2020

Rice is one of the most consumed cereals in the world. Currently, techniques for the authentication and geographical origin of rice is known not to be objective because to depend on the naked eye of a well-trained inspector. DNA fingerprint methods have been shown to be inappropriate for on-site application because the method needs a lot of labor and skilled expertise. Rice consumers want to confirm cultivation origin because they believe price or eating score has a high correlation according to them. Considering rice as a raw material of economic and social value and the recent use of NIR spectroscopy coupled with chemometric methods to authentication and discrimination of geographical origin as an alternative to classical methods in the search for a methodology in line with Green Chemistry, this work investigates the potential of NIR spectroscopy combined with multivariate analysis: PCA (Principal Component Analysis) and HCA (Hierarchical Cluster Analysis) for rapid and non-destructive forensic authentication of rice grains from Brazil and Venezuela. This study investigated the potential of near-infrared spectroscopy, combined with PCA and HCA chemometric technique to the authenticity of rice. It was verified that is feasible and advantageous to implement authenticity detection of different brands, typology and geographical discrimination (Brazil and Venezuela) rice.

Published: June 2020

Nowadays soil contamination practices create hazardous environment impact that is a vital issue to prevent heavy metals from their integration in the food chain. Plant species selected for this study were the ingredients of the traditional Lebanese salad, Tabbouli, composed of parsley and lemon that were selected from Damour, olive and onion from Ghazir, peppermint and tomato from Akkar and bulgur, to fulfill all the requirements for the assessment of the major physicochemical properties and the contamination levels in vegetables from soils with heavy metal elements. The major physicochemical properties of topsoil including pH, organic matter content method (LOI) and texture showed that studied soils were almost neutral pH of 7.09 with an organic matter content of 4.22% and a texture of sandy loam. Concentration ranges of As, Cu, Fe, Zn, Mn, Ni, Ba, Cd, Co, Cr, Pb and P in studied soil samples were determined and assessed by Inductively Coupled Plasma Optical Emission Spectroscopy, following aqua regia digestion and weak acetic acid digestion. Also, similar measurements on studied plant samples following microwave assisted digestion by HNO3/H2O2 were determined and transfer factors from soils to vegetables were accordingly calculated because of their health risk. Results showed that concentrations of most of studied elements in soil and plant samples were recorded above the permissible limits set by International standards for agricultural soils and by International standards for vegetables FAO/WHO. Furthermore, soil to plant transfer is the major path way of human exposure to potentially toxic elements contamination. Good manufacturing and agricultural practices and safety measurements have to be strictly adapted.

Published: June 2020

This work aimed to present the diversity of fungal species in the Poznań- Radojewo park. It was characterized based on literature data, unpublished master’s theses, the authors’ data, as well as data collected during two mycological trips organized by the Mycological Section of the Polish Botanical Society. Between 1980 and 2017, as many as 333 species of macromycetes have been found within the park in Poznań-Radojewo (among them 19% are rare and endangered), including eight protected species (Mitrophora semilibera, Morchella esculenta  (var. esculenta and var. umbrina), Geastrum corollinum, G. fornicatum, Hericium coralloides, and Myriostoma coliforme), as well as two species new to the Polish mycobiota: Psathyrella bipellis and P. larga. The park in Poznań-Radojewo is very important for maintaining a high species diversity of fungi within the city of Poznań. During revitalization works, it is of paramount importance to take the needs of rare, threatened, and protected species under consideration and to preserve the natural character of plant communities. It is also vital to ensure the presence of coarse woody debris at different decomposition phases, which serves as an important substratum type for rare fungi.

BACKGROUND: Cardiovascular disease is one of the main causes of mortality in patients with chronic obstructive pulmonary disease (COPD), and atherosclerosis is a cause of cardiac comorbidities in COPD. However, it is not clear whether airflow limitation is associated with atherosclerosis
irrespective of smoking.OBJECTIVE: To investigate whether airflow limitation is independently associated with vascular stiffness.METHODS: We enrolled 18 893 participants (male 70.5%; mean age 47.5 ± 9.8 years; never smokers 44.2%) who underwent spirometry
and brachial-ankle pulse wave velocity (baPWV) as part of a standard health examination at Ajou University Hospital, Suwon, South Korea, from January 2010 to December 2015.We defined vascular peripheral atherosclerosis as baPWV ≥ 1400 cm/s and airflow limitation as pre-bronchodilator
ratio of forced expiratory volume in 1 sec (FEV1) to forced vital capacity (FVC) <70%.RESULTS: Mean baPWV was higher in subjects with airflow limitation (1477.6 ± 331.7 cm/sec, n = 638) than in those without airflow limitation (1344.1 ± 231.8 cm/sec,
n = 18255, P < 0.001). In multivariate logistic regression analysis, the following were independent predictors associated with peripheral atherosclerosis (P < 0.05): age, male sex, fasting serum glucose, mean blood pressure, serum leukocyte count, serum low density
lipoprotein level and FEV1.CONCLUSION: Airflow limitation was an independent predictor of vascular stiffness irrespective of smoking history, which suggests that airflow limitation is linked with atherosclerosis.

Published: June 2020

BACKGROUND: Chronic tuberculous granulomatous mastitis (CTGM) is a rare form of tuberculosis (TB) treated primarily with anti-TB drugs. Oncoplastic surgery (OS) has been proposed as adjuvant therapy for CTGM.METHOD: We followed for 1 year every CTGM patients and assessed
the efficacy (defined as non-recurrence and no need for corticosteroids) and safety attributable to the standard anti-TB drugs therapy with and without OS.RESULTS: We analysed 128 CTGM cases, including 78 (61%) treated with OS plus anti-TB drugs and 50 (39%) with anti-TB drugs only.
We observed a significantly higher efficacy among those exposed vs. unexposed to OS (100% vs. 92%; prevalence ratio [PR] 1.09, 95% CI 1.00–1.18), with no difference in the number of complications (21% vs. 8%; PR 2.56, 95% CI 0.91–7.26). We also observed that the incidence of post-operative
complications decreased by 50% when OS was postponed from after Month 1 to after completing Month 2 of anti-TB drugs treatment (19% to 8%; PR 0.46, 95% CI 0.13–1.62).CONCLUSION: OS appears to represent an efficacious and safe adjuvant therapy when combined with anti-TB drugs
in the treatment of CTGM patients, but clinical trials are needed to prove this observation.
Perceived Stress and Burnout : The Mediating Role of Psychological, Professional Self-Care and Job Satisfaction as Preventive Factors in Helping Professions
Authors: Hricova Monika , Nezkusilova Jana , Raczova Beata
Published: June 2020

Background: Stress and burnout are among the common causes of absenteeism and fluctu - ation of staff in European workplaces. Therefore, the demand for understanding the predictors of burnout in high risk professions has been growing. The aim of this study is to explore the link between perceived stress and the three dimensions of burnout (emotional exhaustion, depersonalization, and personal accomplishment) while considering the potential mediating role of self-care and job satisfaction that may prevent the transformation of stress into burnout. Methods: A randomly selected group of Slovak social service professionals (N = 689; 618 women) from institutions in 8 districts in Slovakia described their levels of perceived stress, burnout, performed self-care and job satisfaction in self-reported questionnaires. Results: The relationship between stress and emotional exhaustion is solely mediated by certain aspects of job satisfaction: salary, nature of work, and operating procedures. The relationship between stress and depersonalization is mediated by the nature of work, psychological self-care, and professional self-care. However, professional self-care does not prevent but rather facilitates the development of depersonalization in times of high perceived stress. The relationship between stress and personal accomplishment is mediated by psychological and professional self-care as well as by three factors of job satisfaction: co-workers, nature of work and job benefits. When stress increases, satisfaction with co-workers and nature of work prevent the decrease of personal accomplishment. However, job benefits, with increasing stress, may be related to a decrease in personal accomplishment at work. Conclusion: Satisfaction with salary, nature of work, operating procedures and co-workers as well as psychological self-care may prevent the further development of burnout in times of high stress. Yet, professional self-care and job benefits may, in times of increased stress, potentially lead towards specific aspects of burnout (depersonalization and reduction of personal accomplishment).

Authors: Klimmt Christoph , Rosset Magdalena
Published: June 2020

How do advertising and other attempts to influence affect opinions, attitudes, and behavior? The question “how persuasion works” is of still increasing importance for corporations and social science alike. The Elaboration Likelihood Model is one of the most prominent and most frequently cited models of persuasion. The book, which is now in its second revised edition, introduces the main features of Petty and Cacioppo’s model in an easy-to-read and comprehensible manner. Particular attention is paid to the perspectives of communication science and advertising practice: What is the use of the ELM for marketing communication and its investigation?

The book presents the seven fundamental postulates of the ELM, followed by its references to mass communication, particularly advertising. Further chapters are dedicated to the experimental methodology of persuasion research, criticism of the model, and alternative persuasion models.
“Anonymous Feminist”?
Authors: Hallonsten Simon ,   Philosophy Documentation Center
Published: June 2020

Karl Rahner is not usually thought of as a feminist. Though feminist theology has often made recurs to his theological anthropology, Rahner is assumed to offer feminist theology little in terms of an analysis of sex, gender, and human nature. While Rahner’s explicit writings on women appear fragmentary and ambivalent, an investiga­tion of the philosophical and theological underpinnings of Rahner’s theological anthropology shows that Karl Rahner’s understanding of human nature is imbued with a conception of sex and gender that constitutes an important contribution to an understanding of sex, gender, and human nature in theological anthropology in general and feminist theology in particular.
Coagulation Dysfunction
Authors: Fei Yang , Tang Ning , Liu Hefei , Cao Wenjing
Published: June 2020

Context.—

The coronavirus disease 2019 (COVID-19) is a highly contagious respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Coagulation dysfunction is a hallmark in patients with COVID-19. Fulminant thrombotic complications emerge as critical issues in patients with severe COVID-19.

Objective.—

To present a review of the literature and discuss the mechanisms of COVID-19 underlying coagulation activation and the implications for anticoagulant and thrombolytic treatment in the management of COVID-19.

Data Sources.—

We performed a systemic review of scientific papers on the topic of COVID-19, available online via the PubMed NCBI, medRxiv, and Preprints as of May 15, 2020. We also shared our experience on the management of thrombotic events in patients with COVID-19.

Conclusions.—

COVID-19–associated coagulopathy ranges from mild laboratory alterations to disseminated intravascular coagulation (DIC) with a predominant phenotype of thrombotic/multiple organ failure. Characteristically, high D-dimer levels on admission and/or continuously increasing concentrations of D-dimer are associated with disease progression and poor overall survival. SARS-CoV-2 infection triggers the immune-hemostatic response. Drastic inflammatory responses including, but not limited to, cytokine storm, vasculopathy, and NETosis may contribute to an overwhelming activation of coagulation. Hypercoagulability and systemic thrombotic complications necessitate anticoagulant and thrombolytic interventions, which provide opportunities to prevent or reduce “excessive” thrombin generation while preserving “adaptive” hemostasis and bring additional benefit via their anti-inflammatory effect in the setting of COVID-19.
How caged salmon respond to waves depends on time of day and currents
Authors: Johannesen Ása , Patursson Øystein , Kristmundsson Jóhannus , Dam Signar Pæturssonur , Klebert Pascal
Published: June 2020

Disease, pest control, and environmental factors such as water quality and carrying capacity limit growth of salmon production in existing farm areas. One way to circumvent such problems is to move production into more exposed locations with greater water exchange. Farming in exposed locations is better for the environment, but may carry unforeseen costs for the fish in those farms. Currents may be too strong, and waves may be too large with a negative impact on growth and profit for farmers and on fish welfare. This study employed two major fish monitoring methods to determine the ability of Atlantic Salmon (Salmo salar) to cope with wavy conditions in exposed farms. Echosounders were used to determine vertical distribution and horizontal preference of fish during different wave and current conditions as well as times of day. Video cameras were used to monitor shoal cohesion, swimming effort, and fish prevalence in locations of interest. The results indicate complex interacting effects of wave parameters, currents, and time of day on fish behaviour and vertical distribution. During the day, hydrodynamic conditions had stronger effects on vertical distribution than during the night. In weak currents, fish generally moved further down in taller waves, but stronger currents generally caused fish to move upwards regardless of wave conditions. Long period waves had unpredictable effects on vertical distribution with fish sometimes seeking deeper water and other times moving up to shallower water. It is unclear how much the cage bottom restricted vertical distribution and whether movement upwards in the water columns was related to cage deformation. In extreme cases, waves can reach below the bottom of a salmon cage, preventing fish from moving below the waves and cage deformation could exacerbate this situation. Farmers ought to take into consideration the many interacting effects on salmon behaviour within a cage as well as the potential for cage deformation when they design their farms for highly exposed locations. This will ensure that salmon are able to cope when storms and strong currents hit at the same time.

Published: June 2020

Bio-plastics are either bio-based polymers or capable of degradation into simple compounds. The rising development in the production and use of bio-plastics has globally revolutionized the dependency on traditional plastics. The conventional plastics prepared from petroleum, coal and natural gas have been extensively used by humans since antiquity as a prime component of almost all the materials used in day to day life. Since, these plastics are non-biodegradable; they cause serious impact on the environment. Recent years have witnessed the introduction of a wide variety of bio-plastics derived from natural polymers such as starch, cellulose, chitin etc. These bio-plastics are now being utilised in packaging materials, electronics, medical devices; holding immense potential for utility in future. This mini-review confers about types of bio-plastics, their utility in different sectors and their future prospective.

Authors: Stanley H. O. , Egbe V. N.
Published: June 2020

The aim of this study is to determine the impact of hospital wastes indiscriminately dumped at exposed dumpsites within the University of Port Harcourt Teaching Hospital. Ten random samples (100g each) were withdrawn from a depth of 0–15 cm from each sampling site for soil analysis and settling plate technique was used for microbial air quality assessment. The Microbiological assessment of the dumpsites revealed an array of microorganisms viz; Baccilus sp., Staphylococcus sp., Pseudomonas sp., Salmonella sp., Proteus sp. Escherichia coli, Trichophyton sp., Scopulariopsis sp.  Candida albicans,  Fusarium sp., Mucor sp. and Cladosporium sp. and the microbial population dynamics reveals that the bacterial and fungal counts where more abundant on hospital dumpsites when compared to a pristine soil,  as was the heavy metals levels. The air quality assessment of the dump site area reveals that most of the isolated pathogens from the soil analysis could also be airborne. This study has shown that improper dumping of hospital waste impacts deleteriously on the environment and measures must be put in place for proper management to avert any adverse health impact.

Published: June 2020

Introdução: A disfunção pulmonar no pós-operatório de cirurgia cardíaca continua sendo uma das mais importantes causas de morbidade, sendo que o comprometimento da função pulmonar, nessa circunstância, é frequente e contribui, significativamente, para o aumento do tempo de permanência hospitalar. O objetivo deste estudo foi avaliar o comportamento da função pulmonar em pacientes adultos hospitalizados, submetidos à cirurgia cardíaca por esternotomia mediana, no momento a alta da unidade tratamento intensivo, comparado ao quarto dia após a alta dessa unidade. Metodologia: O estudo foi realizado em uma unidade de pós-operatório de cirurgia cardiovascular, após aprovação do Comitê de Ética em Pesquisa. O Termo de Consentimento Livre Esclarecido foi obtido em todos os casos. Incluíram-se pacientes maiores de 18 anos, submetidos à cirurgia cardíaca eletiva. A função pulmonar foi realizada na alta da unidade de tratamento intensivo e, posteriormente, repetida no quarto dia. A função pulmonar foi mensurada pela capacidade vital forçada, pico de fluxo expiratório, além de variáveis do exame físico, como frequência respiratória e ausculta pulmonar. Resultados: 94 pacientes foram submetidos à cirurgia cardíaca eletiva via esternotomia mediana. A média (desvio padrão) de idade foi 50,64 (16,53) anos, com predomínio do sexo masculino (52,1%). A mediana (Q1-Q3) do tempo de permanência na unidade de tratamento intensivo foi de 2,00 dias (2,00-3,00), ao passo que a mediana (Q1-Q3) do tempo de permanência hospitalar foi de 6,00 dias (5,00-8,00). A mediana (Q1-Q3) da capacidade vital forçada e do fluxo respiratório, obtida pela espirometria no pós-operatório, no momento da alta, foi significativamente menor quando comparada ao quarto dia após alta da unidade de tratamento intensivo (p< 0,01). O tempo de permanência na unidade, assim como o tempo de permanência hospitalar não impactou na evolução das variáveis de função pulmonar. Conclusão: A função pulmonar é potencialmente reduzida no período inicial após a cirurgia cardíaca, com evolução gradual, e de recuperação lenta, no curso da recuperação cirúrgica. A manutenção desses valores reduzidos a níveis não críticos por um período prolongado no pós-operatório parece não afetar o desempenho dos pacientes, no que tange a capacidade de respirar profundamente e na efetividade de tosse.

Resumo: A cirurgia guiada é uma técnica de planejamento virtual para instalação de implantes dentários que possibilita maior precisão e confiabilidade para o cirurgião, possibilitando menor morbidade ao paciente. Alguns autores, entretanto, apontam para alguns erros cumulativos durante o processo, desde o planejamento à execução, que podem resultar em desvios no posicionamento dos implantes. Objetivo: Coletar e analisar dados para a verificação do nível de precisão encontrado na obtenção das imagens tomográficas que são utilizadas para planejamento de cirurgias guiadas em implantodontia. Materiais e Métodos: Foram utilizadas três corpos de prova que foram fresados até atingirem as dimensões ideais e foram posicionados para tomada tomográfica em posterior direito, anterior e posterior esquerdo. Foram realizadas 180 medidas em pontos pré-estabelecidos com paquímetro digital, e então, submetidos à tomografia computadorizada de feixe-cônico. Após a obtenção das imagens, os mesmos pontos foram medidos na tomografia e então os valores obtidos na peça fresada e os da tomografia foram comparados e analisados. Resultados: Em 80% das medidas, a tomografia foi superestimada e em 18,33%, mostrou-se menor. Em apenas 01 medida (1,67%), as médias dos corpos de prova e da tomografia impressa foram iguais. Na região anterior, a diferença das aferições da tomografia impressa e do corpo de prova, foi de 0,45 mm, já na região posterior foi de 0,34 mm, em média. Conclusão: A tomografia computadorizada de feixe cônico é uma ferramenta confiável na instalação de implantes com cirurgia guiada, desde que sejam observadas as margens de erro que apresenta e levado em consideração o fato de que a aquisição de imagens é apenas uma das etapas da cirurgia guiada, a qual apresenta erros cumulativos que podem comprometer o resultado final se não forem observados e contornados pela experiência do cirurgião.

Introdução: As Doenças Crônicas Não Transmissíveis (DCNTs) correspondem a um grave problema de saúde pública e representam um empecilho frente ao desenvolvimento humano. Objetivou-se avaliar a relação da cobertura da atenção da básica no período de 2004 à 2009 e seus efeitos sobre as taxas de internações para causas sensíveis em saúde e doenças hipertensivas nas capitais dos estados da região Nordeste do Brasil. Metodologia: Realizou-se estudo ecológico, a partir de dados secundários disponíveis no Departamento de Informática do Sistema Único de Saúde (DATASUS) e do Sistema de Informações Hospitalares do SUS (SIHSUS). Os dados foram tabulados e organizados em formato de gráficos e tabelas. Resultados: Os resultados sobre a distribuição da cobertura de atenção básica, revelaram que Aracaju e Teresina são as capitais com maior cobertura (95,3% e 90,0%, respectivamente); Nas taxas de internações sensíveis à atenção básica, João Pessoa e Teresina aparecem com as maiores taxas, 147,2 e 155,2, respectivamente, no ano de 2005; No que relaciona-se às taxas de internações por doenças hipertensivas, Teresina foi a capital com as maiores taxas de 2004 a 2009 (15,5% e 12,3%, respectivamente), mesmo com a diminuição ocorrida a partir de 2006. Conclusão: De acordo com os resultados encontrados evidencia-se que pode existir uma relação entre a cobertura de atenção básica e as taxas de internações por causas sensíveis. Os dados apresentados não demonstram questões relacionadas à qualidade e efetividade da atenção prestada. Dessa forma, sugere-se que sejam realizados mais estudos sobre a avaliação da efetividade da atenção básica no Nordeste.

Logopenic variant primary progressive aphasia (lvPPA) is the least well defined of the major primary progressive aphasia (PPA) syndromes. We assessed phoneme discrimination in patients with PPA (semantic, nonfluent/agrammatic, and logopenic variants) and typical Alzheimer’s disease, relative to healthy age‐matched participants. The lvPPA group performed significantly worse than all other groups apart from tAD, after adjusting for auditory verbal working memory. In the combined PPA cohort, voxel‐based morphometry correlated phonemic discrimination score with grey matter in left angular gyrus. Our findings suggest that impaired phonemic discrimination may help differentiate lvPPA from other PPA subtypes, with important diagnostic and management implications.
Rapid Fabrication of Self‐Healing, Conductive, and Injectable Gel as Dressings for Healing Wounds in Stretchable Parts of the Body

Skin wounds on stretchable parts of the body including the elbows, knees, wrists, and nape usually undergo delayed and poor healing due to the interference of their frequent motion. Ordinary dressings that are not flexible enough face difficulty to promote wound healing due to the mismatching between the mechanics of the dressing materials and the wounds. In this study, an injectable, biocompatible, self‐healable, and conductive material poly(3,4‐ethylenedioxythiophene): poly(styrenesulfonate)/guar slime (PPGS) is developed for healing wounds with various kinds of movements. As a proof‐of‐principle assay, the healing effect of PPGS is explored on a skin wound model on the nape of rats that often experiences frequent movements. PPGS, which can be prepared within 1 min, successfully accelerates the healing of the wounds. The results suggest that PPGS has great potential in the fields of tissue engineering and biomedicine.
Synthetic Self‐Limiting Structures Engineered with Defective Colloidal Clusters

Published: June 2020

One of the key challenges in the study of self‐assembly with synthetic particles is how to build finite‐sized constructs that resemble self‐limiting structures such as well‐known proteins and biomolecules found in nature. Inspired by this concept, a novel method for realizing self‐limiting self‐assembly of colloidal clusters by establishing design rules to obtain desired final structures using a bottom‐up assembly approach is presented. The constructs identified in this work will be “locked” in a well‐defined configuration as the structure morphologies will not allow them to grow any further. The approach presented here provides two distinct advantages. First, the self‐limiting characteristics of the resulting constructs are preserved no matter how many building blocks are present within the system. Second, the setup of interparticle interactions reflected by interaction matrices are much simpler compared to finite‐sized structures of simple spherical particles which may require engineering pairwise interactions between as many particle types as the number of particles present in the system. The self‐assembly process as well as phase transformation and kinetics of several intriguing finite‐sized configurations are studied. Possible extensions of this concept to produce sophisticated multi‐phased structures where different types of finite‐sized and large assemblies may be present at once are also discussed.

Published: June 2020

Precise electrochemical synthesis under ambient conditions has provided emerging opportunities for renewable energy utilization. Among many promising systems, the production of hydrogen peroxide (H2O2) from the cathodic oxygen reduction reaction (ORR) has attracted considerable interest in past decades due to the increasing market demands and the vital role of ORR in the electrocatalysis field. This work describes recent advances in cathodic materials for H2O2 synthesis from 2e- ORR. By using Pt as a stereotype, the tuning knobs are overviewed, including the intrinsic binding strength of oxygenated species, the intermediate diffusion path and the isolation of Pt–Pt ensembles that enable 2e- ORR pathway from 4e- total reduction. This knowledge is successfully applied to other transition metal systems and leads to the discovery of more efficient alloy catalysts with balanced improvement on both activity and selectivity. In addition, mesostructure engineering and heteroatoms doping strategies on carbon‐based materials, which significantly boost the H2O2 production efficiency as compared to intact carbon sites, are also reviewed. Finally, future directions and challenges of transferring developed catalysts from lab scale tests to pilot plant operations are briefly outlooked.

Composite bilayer multiferroics combining ferroelectric (FE) and ferromagnetic (FM) thin‐film materials in a heterostructure and exhibiting magnetoelectric (ME) coupling effect are of great scientific and technological interest. In particular, electronically driven ME coupling implies that the FE polarization orientation affects the magnetic properties of FM at the interface with FE. Unlike metals, where the electric field penetrates over distances of 1–2 unit cells only, magnetic semiconductors, particularly doped EuS, with a ≈10 nm screening length appear a viable alternative. In addition, EuS exhibits a metal–insulator transition, thus offering new functionalities in nanoelectronics. Meanwhile, ultrathin polycrystalline films of doped HfO2, such as Hf0.5Zr0.5O2 (HZO), stabilized in the noncentrosymmetric orthorhombic phase, are identified as a novel class of robust FE materials. In this work, FM EuS integrated with FE HZO in a bilayered structure is promoted as a prospective composite multiferroic. The functionality of both ultrathin FM‐EuS and FE‐HZO layers as well as their compatibility in a capacitor configuration is demonstrated. The comprehensive information on the structural, chemical, and electronic properties of EuS/HZO interface endorses it as a promising medium for magnetoelectric coupling phenomena, particularly, the effect of polarization reversal in FE‐HZO on the magnetic and transport properties in EuS.
