AbstractOrganic light‐emitting diodes (OLEDs) fabricated using organic thermally activated delayed fluorescence materials as sensitizers have recently achieved significant advancements, but the serious efficiency roll‐offs are still troublesome in most cases. Herein, a tailor‐made multifunctional luminogen SBF‐BP‐SFAC containing 9,9′‐spirobifluorene (SBF) and spiro[acridine‐9,9‐fluorene] (SFAC) as electron donors and carbonyl as an electron acceptor is synthesized and characterized. SBF‐BP‐SFAC has the advantages of high thermal stability, aggregation‐enhanced delayed fluorescence, and balanced carrier transport ability, and prefers horizontal dipole orientation. Highly efficient OLEDs employing SBF‐BP‐SFAC as an emitter radiate intense cyan light with outstanding external quantum efficiencies (ηexts) of up to 30.6%. SBF‐BP‐SFAC can also serve as an excellent sensitizer for orange fluorescence, phosphorescence, and delayed fluorescence materials, providing excellent ηexts of up to 30.3% with very small efficiency roll‐offs due to the fast Förster energy transfer as well as exciton annihilation suppression by bulky spiro donors. These outstanding performances demonstrate the great potential of SBF‐BP‐SFAC as an emitter and sensitizer for OLEDs.

AbstractIntroductionGlobal estimates on numbers of persons in early stages of Alzheimer's disease (AD), including prodromal and preclinical, are lacking, yet are needed to inform policy decisions on preventive measures and planning for future therapies targeting AD pathology.MethodsWe synthesized the literature on prevalence across the AD continuum and derived a model estimating the number of persons, stratified by 5‐year age groups, sex, and disease stage (AD dementia, prodromal AD, and preclinical AD).ResultsThe global number of persons with AD dementia, prodromal AD, and preclinical AD were estimated at 32, 69, and 315 million, respectively. Together they constituted 416 million across the AD continuum, or 22% of all persons aged 50 and above.DiscussionConsidering predementia stages, the number of persons with AD is much larger than conveyed in available literature. Our estimates are uncertain, especially for predementia stages in low‐ and middle‐income regions where biomarker studies are missing.

AbstractConstruction of an intimate film/substrate interface is of great importance for a photoelectrode to achieve efficient photoelectrochemical performance. Inspired by coordination chemistry, a polymeric carbon nitride (PCN) film is intimately grown on a Ti‐coated substrate by an in situ thermal condensation process. The as‐prepared PCN photoanode exhibits a record low onset potential (Eonset) of −0.38 V versus the reversible hydrogen electrode (RHE) and a decent photocurrent density of 242 μA cm−2 at 1.23 VRHE for water splitting. Detailed characterization confirms that the origin of the ultralow onset potential is mainly attributed to the substantially reduced interfacial resistance between the Ti‐coated substrate and the PCN film benefitting from the constructed interfacial sp2 N→Ti coordination bonds. For the first time, the ultralow onset potential enables the PCN photoanode to drive water splitting without external bias with a stable photocurrent density of ≈9 μA cm−2 up to 1 hour.

Published: June 2022

AbstractHerein, we demonstrate that living Suzuki–Miyaura catalyst‐transfer polymerization (SCTP) using a RuPhos Pd G3 precatalyst is a versatile method for the precision synthesis of various donor–acceptor alternating conjugated polymers (DA ACPs). First, the living SCTP of biaryl monomers with combinations of both medium to strong A and D were optimized to produce DA ACPs with controlled number average molecular weight (Mn), narrow dispersity (Ð, 1.05–1.29), and high yield (>87 %). Moreover, its expansion to controlled polymerization (Mn=9.2–40.0 kg mol−1) of an A1‐D‐A2‐D quateraryl monomer containing diketopyrrolopyrrole (DPP; strong A) was successful. The living SCTP also enabled the efficient one‐pot synthesis of various diblock and triblock copolymers. Lastly, the DA ACPs showed tunable optical band gap (Egopt, from 1.29 to 1.77 eV) and highest occupied molecular orbital (HOMO) level (from −5.57 to −4.75 eV), while their block copolymers exhibited broad absorption ranges and promising visible light‐harvesting properties.

Published: June 2022

AbstractA novel type of porous composites MOF@COF was successfully constructed through decorating covalent organic framework (COF) crystals on the surface of amino‐functionalized metal organic framework (NH2‐MOF). This material has proven to be an excellent catalyst support because it not only overcomes the shortcoming of MOF instability but also combines the advantages of both high specific surface areas. Pd (OAc)2 is anchored on MOF@COF to obtain MOF@COF‐Pd catalyst. MOF@COF‐Pd is used to catalyze the C–C coupling reaction of pyrimidine sulfonate and aryl boronic acid. The catalyst has the advantages of high stability, catalytic activity, recyclability, and no metal loss. And the application of MOF@COF hybrid materials was expanded in the field of catalysis.
Soft, fully bio‐based poly‐hydroxyl thermosets based on catalyst‐free transesterification with decent re‐processability
Authors: Li Jie , Zhang Shufen , Ju Benzhi 
Published: June 2022

AbstractMost of the vitrimers based on transesterification (TE) highly rely on the usage of large amounts of catalysts to promote exchange reactions to obtain re‐processability, which brings additional concerns on human health or environmental issues. Herein, we demonstrate that TE vitrimers with soft networks (low Tg), though free of catalysts nor any other special design, can be still dynamic enough to be easily re‐processed. In this paper, fully bio‐based and catalyst‐free thermosets from epoxidized soybean oil (ESO) and bio‐dicarboxylic acids (DA) were synthesized and found to possess decent re‐processability. By means of compressive remolding (10 MPa, 160°C), the ESO‐DA thermosets heal visible defects within 30 min and restore the mechanical strength within 3 h. Upon 3 times of mechanical recycling, the mechanical strengths remain nearly unchanged compared with those of pristine thermosets. Stress relaxation experiments confirm the network rearrangement at high temperatures (≥150°C) as well as vitrimeric flow of the materials. The materials are also capable of being welded without solvents under a small pressure. Lastly, a facile fusion method was employed to tune the mechanical strength of the recycled ESO vitrimers.
Using marsh organs to test seed recruitment in tidal freshwater marshes
Authors: Lane Stefanie L. 
Published: June 2022

AbstractPremiseSeed recruitment niches along estuarine elevation gradients are seldom experimentally field‐tested under tidal regimes of the Pacific Northwest of North America. Addressing this knowledge gap is important to better understand estuary restoration and plant community response to sea level rise.MethodsGermination was tested in marsh organ mesocosms across an elevation gradient (0.5–1.7 m above mean sea level). Seeds were sown on sterile peat moss, and the tops of pipes were secured with horticultural “frost cloth” to ensure no experimental seeds were washed out and no new seeds were introduced. The trials tested artificial and overwinter chilling regimes, as well as the presence and/or absence of a near‐neighbor transplant.ResultsCarex lyngbyeihad significant elevation‐driven germination after overwinter and artificial chilling.Schoenoplectus tabernaemontanihad near‐significant germination across elevation after overwinter chilling, and germination in the absence of competition was significantly greater than with a near‐neighbor transplant.DiscussionCarex lyngbyeihad the highest germination rate at higher elevations, which suggests restricted seed recruitment potential and required clonal expansion to extend into lower marsh elevations. Identifying species‐specific recruitment niches provides insight for restoration opportunities or invasive species monitoring, as well as for estuary migration under sea level rise.

AbstractDie Tageslichttechnik ist ein interdisziplinäres Fachgebiet zwischen Bauphysik und Lichttechnik und verwirklicht mittels neuartiger Spiegeloptiken verbesserte Schutzfunktion vor Überhitzung, jedoch gleichzeitiger Versorgungsfunktion mit natürlichem Tageslicht, wodurch eine Gesamtenergieeinsparung von verglasten Gebäuden von bis zu 30 % ermöglicht wird. Im Rahmen des Green Deals wird von der EU‐Kommission eine Richtlinie zur Gesamtenergieeffizienz von Gebäuden (EPBD) angestoßen, die Teil eines umfassenden Gesetzespaketes mit der ambitionierten Zielsetzung ist, emissionsfreie Gebäude zu definieren und damit die Reduktion der CO2‐ Emissionen in Europa voranzutreiben. Die Tageslichtumlenktechnik, die im Winter solare Zugewinne, im Sommer einen Schutz vor Überhitzung und ganzjährig die Tageslichtautonomie fördert, kann eine ganz wesentliche Rolle in der Umsetzung dieser ehrgeizigen Ziele spielen. In diesem Beitrag wird eine neue Tageslichtumlenktechnik vorgestellt, mit der sich auch mittels eines innenliegenden Behangs ein gges‐Wert von 0,05 sogar in offener und durchsichtiger Lamellenlage mit Tageslichteintrag realisieren lässt.

AbstractThe preparation and characteristic of nanorod‐like Zn2GeO4 doped with Eu3+ or zinc germanate (ZGO):xEu3+ (x = 0 ÷ 0.05), which was synthesized using the hydrothermal method, are described. The influence of Eu3+‐doping ions on the structure and the optical properties of ZGO was also investigated. According to the photoluminescence spectra, ZGO:xEu3+ nanophosphors gave a red emission due to the 5D0→7F2 emission of Eu3+ ions. In accordance with Judd–Ofelt theory, the intensity parameters for f–f transitions from the emission and absorption spectrum were determined. At the 5D0 excited state of Eu3+, total spontaneous emission probabilities (AR), lifetimes (τR), branching ratios (βR), and quantum efficiency (η) were calculated. The ZGO:xEu3+ (x = 0.02, 0.03, 0.04) phosphor showed the branch ratio β (5D0→7F2) > 60%, indicating that the phosphors prepared here have a promising potential as laser light. The sample with a concentration of 0.04Eu3+ achieved the highest quantum efficiency of 84%, suggesting that it has potential light‐emitting diode applications.

Published: June 2022

AbstractSynthetic biology [synbio] applications have the potential to assist in addressing significant global health and environmental challenges. Australian research institutes are investing in formative research to develop synbio technologies capable of meeting these challenges. Alongside the laboratory research, investigating the broader social, institutional, and ethical considerations that synbio presents has been a priority. We conducted targeted qualitative research to uncover the barriers and opportunities for a range of multisectoral stakeholders identified as potential end‐users of the science under development. The research provides insights into the research implementation environment for three synthetic biology applications: (1) gene editing cane toads (Rhinella marina) to reduce their environmental impact; (2) engineering bacteriophages to combat antimicrobial resistance in humans; and (3) engineering microbes to improve biomining efficiency in the mining industry. In‐depth interviews (N = 23) with government, research and civil society representatives revealed key challenges in the impact pathway for each application. The strongest themes uncovered during interviews related to perceived negative public attitudes towards genetic technologies, a lack of investment in critical research infrastructure, unclear regulatory pathways and the presence of a strong social and environmental imperative underpinning technology development. These findings reveal specific entry points for further engagement with the most immediate end‐users of synbio. Separate from research on public attitudes to synbio, the cases highlight the various hurdles to achieving research impact, according to experts who will likely use, approve or invest in these applications in the future. The themes uncovered inform avenues for strengthening engagement and research coordination in Australia and elsewhere.

Published: June 2022

AbstractIn this study, a controlled drug delivery system (DDS) was developed by coaxial electrospinning. Fabricate a controlled DDS using electrospun nanofibers formed with a single concentric nozzle is challenging because of the rapid initial release rate. Therefore, in this study, electrospinning was conducted using dual or triple concentric nozzles to fabricate controlled DDSs. Polycaprolactone and poly(ethylene oxide) were used as the shell and core polymeric materials, respectively, and curcumin was used as the model drug. The spinning feed rate was controlled, and dual and triple concentric nozzles were used to manipulate the shell thickness of the nanofiber. Increasing the shell thickness significantly lowered the release rate. The triple concentric nozzle was effective to obtain a slower release rate than dual concentric nozzle. The coaxial electrospun nanofibers were characterized using optical microscopy and infrared spectroscopy.

Published: June 2022

AbstractIncreasing regulatory obligations to adapt and execute environmentally friendly operations make it critical for businesses to pursue strategies that can strengthen their competitive edge in the market. Academics and practitioners alike have recently gravitated toward exploring how knowledge acquisition activities might improve business outcomes. To address this growing research interest, this study investigates the critical roles of green knowledge acquisition in enhancing green knowledge management and green technology innovation activities in improving corporate environmental performance, positioning resource commitment as a moderator. The research model has been assessed using structural equation modeling with survey data from 283 Indian manufacturers, demonstrating that green knowledge acquisition significantly impacts green knowledge management and green technology innovation. The statistical findings also show that green technology innovation acts catalyzes the translation of green knowledge management into improved corporate environmental performance. The results demonstrate that resource commitment moderates green knowledge acquisition's interaction with green knowledge management and green technology innovation, providing practical insights enabling managers to focus on planning, allocating, and budgeting resources for effective green practices that can contribute to improving corporate environmental performance.
The theory of tumor ecosystem
Authors: Chen Xueman , Song Erwei 
Published: June 2022

AbstractCancer cells can be conceived as “living organisms” interacting with cellular or non‐cellular components in the host internal environment, not only the local tumor microenvironment but also the distant organ niches, as well as the immune, nervous and endocrine systems, to construct a self‐sustainable tumor ecosystem. With increasing evidence for the systemic tumor‐host interplay, we predict that a new era of cancer therapy targeting the ecosystemic vulnerability of human malignancies has come. Revolving around the tumor ecosystem scoped as different hierarchies of primary, regional, distal and systemic onco‐spheres, we comprehensively review the tumor‐host interaction among cancer cells and their local microenvironment, distant organ niches, immune, nervous and endocrine systems, highlighting material and energy flow with tumor ecological homeostasis as an internal driving force. We also substantiate the knowledge of visualizing, modelling and subtyping this dynamically intertwined network with recent technological advances, and discuss ecologically rational strategies for more effective cancer therapies.

AbstractThere have been several arguments for the need to generate evidence‐based creative forms of psychological interventions in Improving Access to Psychological Services (IAPT), the main primary mental health provider in hospitals in England, UK. In this feasibility study, we sought to identify helpful and unhelpful factors of a new creative group psychotherapy, titled Arts for the Blues. We also wanted to find out whether the research tools used were acceptable and sensitive. We therefore engaged a group of seven patients attending an IAPT service in the North West of England, and a group of six staff working in the same service, to attend one creative workshop each, followed by a focus group. The two focus groups were transcribed and analysed using thematic analysis. We also collected pre‐ and post‐measures of depression (PHQ‐9) and anxiety (GAD‐7), measures commonly used in IAPT services, plus measures of well‐being (WHO‐5), the PANAS, and goal‐setting, which were considered for acceptability and sensitivity. We received largely positive responses from service users and staff in the use of creative methods in psychotherapy. Although the measures used had limitations due to the short duration of one‐off creative workshops, we found that they were sensitive enough, easy to complete and, thus, were acceptable. We concluded that Arts for the Blues is a promising intervention in IAPT, especially since it is shaped by service users and staff working in these services. Further work is needed to establish the effectiveness of this new intervention.
The professional identity of school counsellors in East and Southeast Asia
Authors: Harrison Mark Gregory 
Published: June 2022

AbstractA strong counsellor professional identity is associated with the provision of more effective school counselling programmes. However, many school counsellors in East and Southeast Asia carry out wide‐ranging and poorly defined roles, occupy marginalised positions in schools, and have limited access to communities of practice and professional development. To provide more effective support for children’s well‐being, a greater focus on the professional identity of school counsellors in the region is needed. A significant task for professional school counselling organisations is the promotion of counselling in schools as an important and distinct professional role.

AbstractBacterial diseases, such as American Foulbrood (AFB) and European Foulbrood (EFB), are known to have catastrophic effects on honey bees (if left to spread, can wipe out entire colonies), leading to severe financial losses in the beekeeping industry. The aim of this study was to evaluate the pharmacological properties of methanol extract and its fractions (ethyl acetate, hexane, water) derived from Dicranum scoparium Hedw., which could be utilized as a potential drug to prevent the bacterial diseases (AFB and EFB) affecting the honey bees. For this purpose, crude methanol extract and ethyl acetate/hexane/water fractions were prepared from the aerial part of D. scoparium, collected from Trabzon province. Bio‐guided fractionation of the extract and its fractions led to the first‐time isolation of five compounds. The structure of all compounds was elucidated by nuclear magnetic resonance (NMR) spectroscopy, ultraviolet (UV) spectral analysis, Fourier‐transform infrared spectroscopy (FT‐IR), liquid chromatography quadrupole time‐of‐flight mass spectroscopy (LC‐QToF‐MS), and by comparison of their NMR data with that of literature. The analysis of these compounds revealed significant antibacterial and sporicidal activities against bacteria causing larval diseases in honey bees. The antibacterial activity of these compounds ranged from 0.6 to 60 μg/mL against AFB and EFB causing bacteria. Therefore, the natural raw extract and fractions of D. scoparium could be used as potential therapeutic agents against bacterial agents affecting honey bees.

Published: June 2022

AbstractThe association between personality traits, life balance domains, and work addiction among entrepreneurs was investigated. Multiple regression and canonical correlation analysis of 106 participants indicate a significant relationship between personality traits, life balance domains, and work addiction. In particular, neuroticism was positively related to work addiction, as suggested in earlier studies. Among all the life balance domains five of the 10 life balance domains had a significant positive relationship with work addiction: positive orientation, substance use, sleep disturbance, stress/anxiety, and friendship. Results obtained from this study will help career and mental health counselors better understand entrepreneurs’ needs and life balance domains. By identifying neuroticism and stress levels among entrepreneurs, career counselors can better understand work addiction tendencies and use appropriate interventions accordingly.
