Published: June 2021

AbstractThe dispersion of heterogeneous catalyst is directly related to the performance. In this work, highly dispersed Cu/graphene catalyst was successfully prepared by adopting a “template genetic inheritance” (TGI). The metal‐organic frameworks (MOFs) were introduced between the graphene sheets. Due to the spatial structure of MOFs, the Cu atoms arranged in the expected direction after removing the MOFs skeleton, which lead to a highly orderly dispersion of the Cu particles with uniform sized. Meanwhile, graphene provided a large specific surface area and a carbon source for in‐situ reduction of CuO. Furthermore, the CO2 hydrogenation to methanol performance was analyzed and more than 22 % conversion of CO2 and 84 % selectivity of methanol was achieved. This work provides a simple and novel strategy for the preparation of highly dispersed metal particle supported catalysts, which may be used in catalysis and other fields.

Published: June 2021

AbstractHerein, CoMoO4 nanoneedles were first directly grown on carbon cloth through a facile one‐pot water bath method. Interestingly, with the extension of reaction time, the mass loading of CoMoO4 on carbon cloth (CoMoO4/CC) increases gradually. As a pseudocapacitors material, the CoMoO4/CC electrode obtained at 10 hour (CoMoO4/CC‐10) displays a higher specific capacitance (2100 F/g at a current density of 1 A/g) than those of the other CoMoO4/CC electrodes. Furthermore, the CoMoO4/CC‐10 electrode also shows a good rate performance 64.29 % and excellent cycle property 94.53 % after 10000 cycles. An asymmetric supercapacitor device using the CoMoO4/CC‐10 as a positive and active carbon (AC)/CC as a negative electrode achieves high specific capacitance 184 F/g at the current density of 1 A/g, specific energy 65.42 Wh/kg (with the specific power 2880 W/kg), specific power 12000 W/kg (with the specific energy 40.18 Wh/kg) and cycle performance 94.29 % after 10000 times. These electrochemical performances demonstrate the as‐prepared CoMoO4 nanoneedles will be a promising pseudocapacitor material for application in energy storage.

Published: June 2021

AbstractAs the most toxic heavy metal, mercury (Hg) has been considered as the greatest environmental threat and it reach ubiquitous in industrial waste water and extended to environment. The detection of Hg2+ in environmental water is a crucial work for both protecting the environment and human health. Colorimetric assay exhibits visual discriminating and simple readout. This work presents the selective sensing of metal ion (Hg2+) by silver particles (Ag NPs), which were functionalized by galactosamine and synthesized via simple one pot method, with the average particle diameter of 18.75±0.49 nm. The limit of detection (LOD) was calculated as low as 7.92 nM. The colorimetric probe can also be performed in real water sample with good selectivity, and recovery was found to be 95–102 %, indicating can be used for on‐line determination of Hg2+ in the complex aqueous solutions. Additionally, the good catalytic performance of Ag NPs was demonstrated by hydrogenation of p‐nitrophenol and potassium ferricyanide in water samples.

Published: June 2021

AbstractPhototherapy in the second near‐IR (1000–1700 nm, NIR‐II) window has achieved much progress because of its high efficiency and relatively minor side effects. In this paper, a new NIR‐II responsive hollow magnetite nanocluster (HMNC) for targeted and imaging‐guided cancer therapy is reported. The HMNC not only provides a hollow cavity for drug loading but also serves as a contrast agent for tumor‐targeted magnetic resonance imaging. The acid‐induced dissolution of the HMNCs can trigger a pH‐responsive drug release for chemotherapy and catalyze the hydroxyl radical (·OH) formation from the decomposition of hydrogen peroxide for chemodynamic therapy. Moreover, the HMNCs can adsorb and convert NIR‐II light into local heat (photothermal conversion efficacy: 36.3%), which can accelerate drug release and enhance the synergistic effect of chemo‐photothermal therapy. The HMNCs show great potential as a versatile nanoplatform for targeted imaging‐guided trimodal cancer therapy.

Published: June 2021

AbstractEvaluation of nanoparticles obtained from starch is still on a laboratory scale and many challenges need to be overcome up to the industrial scale. In this review, information about the study and development of nanostarches are reported based on a discussion of concepts, production methods, as well as physico‐chemical and technological characterization, safety and applications. The usual methods of producing nanostarches (such as acid hydrolysis, enzymatic pretreatment, high pressure homogenization and ultrasound) are discussed in this review, as well as the advancement of applications in the food industry (as in Pickering emulsion, carriers, films and nanocomposite production). Due to the wide variety of data, a protocol for the analysis of starch nanostructures is suggested. However, methods for quantifying starch nanoparticles are based on yield by weight, and no quantification method has yet been presented for processed products. All reports present a promising future for several areas, both in research and industrial applications, as they are considered as open doors to the many challenges on this research area.

Published: June 2021

AbstractNumerous natural materials are porous, contain free gas and are scattering light strongly. Scattering brings about a strong trapping of light and an associated prolonged transit time for photons through a medium. In contrast to the matrix materials, gas enclosures require very narrowband laser radiation for probing. We have in the present study used the gas in scattering media absorption spectroscopy method to study free oxygen in thin (cm) samples utilizing a tunable diode laser, while a pulsed dye laser was employed in corresponding measurements on larger samples, up to the meter scale. Time‐resolved spectroscopy was in both cases used to assess the temporal distribution of the detected photons, mapping the path lengths through the media, which ranged between few centimeters up to 100 m. This study explores the feasibility to extend recent successful monitoring of gases in neonatal infant lungs to the case of larger children or even adults, which could have very important applications, for example, in ventilator setting optimization for severely ill patients, suffering, for example, from SARS‐CoV‐2. The conclusion of our work is that this goal most realistically can be reached by applying intratracheal laser light illumination at the 1 W power level, employing a tapered amplifier, injected with a distributed feedback diode‐laser oscillator output and combined with wavelength‐modulation spectroscopy.

Published: June 2021

AbstractNeuroblastoma (NB) is an estrogen‐dependent tumor. Mono‐2‐ethylhexyl phthalate (MEHP) has an estrogen‐like effect. However, the effects of MEHP on the progression of NB are not well illustrated. This study was to clarify the effect of Notch pathway on proliferation and cell cycle of SH‐SY5Y cell induced by MEHP. The viability of SH‐SY5Y and BE2C cells were detected by CCK8; cell cycle and apoptosis were detected by flow cytometry; the protein expression levels of Notch pathway and cell cycle related proteins were detected by Western‐blot. Results show that MEHP exposure can promote cell proliferation and altered the cell cycle. MEHP exposure can up‐regulate the expression of C‐MYC, Cyclin D1, Bcl‐2 and affected the Notch pathway. In conclusion, MEHP exposure can promote NB cell proliferation and affect the cell cycle and apoptosis. Notch pathway plays a critical role in accelerating the cell cycle and inhibiting the apoptosis of SH‐SY5Y cells caused by MEHP.

AbstractNasopharyngeal carcinoma (NPC) is an unnoticeable malignant tumor with a high potential of lymphatic metastasis, and its prevalence is high in Asia. Ionizing radiation is the mainstay of treatment for patients with NPC without metastasis. However, patients with metastatic lesions require advanced treatments such as chemotherapy. The present study investigated the apoptotic effect of luteolin‐7‐O‐glucoside on NPC cells and elucidated its underlying signaling mechanisms. The results revealed that luteolin‐7‐O‐glucoside significantly reduced the proliferation of NPC cell lines (NPC‐039 and NPC‐BM). Flow cytometry and morphological analysis results demonstrated that luteolin‐7‐O‐glucoside treatment induced S and G2/M cell cycle arrest, chromatin condensation, and apoptosis. In addition, mitochondrial membrane potential was observed to be depolarized with an increasing concentration of luteolin‐7‐O‐glucoside. Proteins involved in the extrinsic and intrinsic pathways of apoptosis, such as death receptor, caspase‐3, caspase‐8, caspase‐9, and Bcl‐2 family proteins (Bax, t‐Bid, Bcl‐2, and Bcl‐xL), were downregulated and upregulated after treatment with luteolin‐7‐O‐glucoside, respectively. Moreover, the addition of a PI3K/AKT inhibitor enhanced the activation of poly‐ADP‐ribose‐polymerase (PARP) and attenuated cell viability, indicating that luteolin‐7‐O‐glucoside induced apoptosis in NPC cells through the AKT signaling pathway. These results indicated that the apoptosis of NPC cells modulated by luteolin‐7‐O‐glucoside may be preceded by mitochondrial depolarization, cell cycle arrest, extrinsic and intrinsic apoptosis pathway activation, and AKT signaling modulation. Thus, luteolin‐7‐O‐glucoside can be a promising anticancer agent against human NPC.

Published: June 2021

AbstractMultidimensional or multiplex bioanalysis represents a crucial approach to improve diagnostic precision, increase assay throughput and advance fundamental discoveries in analytical industry, life science, and nanomedicine. Along this line, bio‐interfacing magnetic particles have been playing an important role. Fully exploiting the properties of magnetic particles is the key to tailoring recent technology development for better translational outcomes. In this mini‐review, typical magneto‐physical dimensions of magnetic particles are introduced. Recent progress of implementing these dimensions with advanced sensor and actuator technologies in multiplex bioanalysis is discussed. Outlooks on potential biomedical applications and challenges are provided.
Successful treatment of a presumed autoimmune subepidermal bullous dermatosis in a horse

Published: June 2021

AbstractAutoimmune subepidermal bullous dermatoses are rarely described in the horse. Few reported cases have not been cured favourably. A 15‐year‐old male horse was presented with general ulcerative and blistering lesions on skin and oral cavity. Histopathological evaluation of skin biopsy specimens revealed dermal and epidermal separation with subepidermal vesicles and mild infiltration of inflammatory cells (predominantly mononuclear cells). Clinical, historical and histopathological examinations demonstrated a subepidermal vesicular dermatosis. Treatment was initiated with dexamethasone at 0.05 mg/kg IM daily for 3 days, followed by oral prednisolone at 1 mg/kg daily for 2 months. A complete resolution of clinical signs was observed after 2 months, and no recurrence was observed after 24 months follow‐up. No adverse effects were observed.
Vulnerability and resilience of power systems infrastructure to natural hazards and climate change
Authors: Schweikert Amy E. , Deinert Mark R. 
Published: June 2021

AbstractThe value of critical infrastructure rests in the services they provide. Electricity in particular underpins the operation of hospitals, schools, financial systems, transportation assets, telecommunications, and water treatment, and affects many other aspects of daily life. There is an emerging recognition of power systems as complex adaptive systems and a proliferation of work on how to make them more resilient in the face of natural hazards and climate change. However, the term “resilience” is often used to encompass important, but distinct, aspects of infrastructure analysis including vulnerability, asset hardening, resistance to failure and risk management. As work in this domain has evolved through disciplines from risk management, economics, engineering and policy, the term “resilience” has often remained vague or referred to broad aspects of infrastructure performance under hazard events. Here we argue it is important to distinguish asset hardening and risk management from aspects of a system that allow it to deliver services even when some of its components fail. Understanding infrastructure vulnerability and risk are key components of resilient power system assessments. However, differentiating vulnerability from functional resilience (service delivery even when components fail) can help identify gaps in data, modeling and decision making. We propose that continued progress in this area can be made by unifying these areas of work through (1) understanding vulnerability and risk management in the context of hazards and climate change and (2) an orientation of resilient service delivery as a unifying concept for resilience analysis.This article is categorized under:

Life Design for an Inclusive and Sustainable Future
Authors: Di Maggio Ilaria , Ginevra Maria Cristina , Santilli Sara , Nota Laura , Soresi Salvatore 
Published: June 2021

AbstractSocieties today are highly complex and often impacted by uncertainty, rapid change, globalization, and inequality, all of which have significant impact on the wellbeing of people. These changes make it more difficult not only for a great part of the population to live in the present, but also for succeeding generations to aspire to and imagine a possible future. Considering this, career guidance needs a change of pace that can only be associated with investments in inclusion and sustainability. In this chapter we provide a brief historical excursion through the social role that career guidance has played through the years, and then outline possible actions that career guidance professionals could take so as to embrace, sustain, and foster the creation of a better future for everyone and to contribute to the creation of inclusive and sustainable societies.
Developing Coping Skills in the Early Years: A Positive Educational Approach
Authors: Frydenberg Erica , Deans Jan , Liang Rachel 
Published: June 2021

AbstractThere are numerous ways to construe positive education in the early years, particularly as it relates to wellbeing and positive emotional outcomes. The teaching of coping skills provides tools for wellbeing within a positivist framework through emphasising the use of productive coping strategies and reducing the use of unhelpful, non-productive strategies. This chapter provides an example of teaching coping skills in early childhood: the Early Years Coping Project. The project helped young children articulate and understand coping constructs and provided tools to help parents and teachers to assess children’s coping. Visual tools facilitated the development of children’s coping skills in classroom activities. Parents were encouraged to develop their parenting skills and their own coping, utilising the emotion and coping language that is common to them and their children. The parent program was subsequently adapted in a format that was readily communicated to a culturally diverse population, using the generic frameworks and constructs of coping. Coping concepts and constructs have subsequently been incorporated into a COPE-Resilience curriculum. We highlight several applications and extensions of the curriculum. Coping skills provide a template for healthy social-emotional development that can be utilised in different contexts throughout life.
Helping Students Find Their Way to Meaning: Meaning and Purpose in Education
Authors: Steger Michael F. , O’Donnell Maeve B. , Morse Jessica L. 
Published: June 2021

AbstractMeaning in life is a cornerstone of wellbeing and flourishing. Emerging generations express intense interest, and even anxiety, about living and working in a meaningful way, yet contemporary society seems ill-equipped to provide them with constructive pathways to meaning. In this chapter, we place meaning in life theory and research in the context of positive education, and suggest a number of simple activities and tools, as well as a broader perspective on meaning and purpose, that both can be integrated into positive education programs and also may be used as the very basis for integrating such programs. Meaning in life captures our universal desire for life to be significant, coherent, and purposeful. By helping students begin and continue to take steps on pathways to meaning, positive educational institutions may profoundly assist the flourishing of students in their care and the communities in which those institutions and students thrive.
Positive Education with Disadvantaged Students
Authors: Roffey Sue , Quinlan Denise 
Published: June 2021

AbstractIf anyone needs positive education, it is young people who struggle with adversities in their lives and for whom the school may be their only place of refuge, stability, and welcome. Students who experience challenging life events often do not learn or behave well at school, and as a consequence may be marginalised, punished, or even excluded. These pupils then learn that they are unwanted and worthless. This can have a far-reaching impact not only on these young people, but also on others at the school and our future communities. This chapter outlines major issues that young people are facing across the world, associated outcomes, protective factors, and how schools can help. We include case studies at the school, city, and community levels, describing actions to address the needs of disadvantaged students and the impact these are having, illustrating specific aspects of positive education that can make a difference and may help to break negative intergenerational cycles. What we have learned through these studies makes a positive difference; what is good practice for disadvantaged young people is invariably good practice for all students.
Four Fundamental Distinctions in Conceptions of Wellbeing Across Cultures
Authors: Joshanloo Mohsen , Van de Vliert Evert , Jose Paul E. 
Published: June 2021

AbstractOne of the key roles of culture is to shape how human groups pursue personal and collective wellbeing, and thus each culture contains prescriptions and customs about how to achieve optimal functioning and wellbeing. This chapter identifies four fundamental differences in the conceptualizations of mental wellbeing across cultures. The identified differences are in the centrality of hedonic experience, self-enhancement, autonomy, and the relevance of contextual factors in determining wellbeing. These overlapping dynamics provide a framework for categorizing and making sense of existing cross-cultural findings on mental wellbeing. The chapter discusses the theoretical and empirical implications of the reviewed cross-cultural findings for international measurements of wellbeing. We argue that various measures of wellbeing may function differently in different global regions, with crucial implications for how countries are ranked based on wellbeing. Our review also highlights the relevance of cross-cultural variations in the concepts of wellbeing for designing interventions and policies and evaluating their effectiveness across cultures.
Teacher and Staff Wellbeing: Understanding the Experiences of School Staff
Authors: McCallum Faye 
Published: June 2021

AbstractThe health of the teaching profession is essential for the innovation and productivity potential of our young people. Teachers are faced with preparing young people for an unknown future, with the reduction of manual tasks and an increased focus on people skills, problem-solving, and creative thinking. Teachers are critical in helping students achieve, belong, and develop socially and emotionally. But how well prepared are teachers and other school staff for shifting conditions, and how satisfied and productive are they? The reality is that many teachers, leaders, and school staff are struggling. Drawing on two research studies, this chapter explores experiences of staff wellbeing. Findings indicate that for young people to be well, to achieve at school, and to be prepared for the future, teachers must also be well. Strategies for supporting teacher wellbeing and implications for the future are discussed. A well-educated population is key to a nation’s prosperity, peace, and human flourishing.
