Authors: Panigrahi Sonia , Rout Sandeep , Sahoo Gyanaranjan , Gupta Sachin , Kumar V. S. Kishan
Published: July 2021

Aims: The impact of bleaching chemicals on the gloss and film thicknesses of poly urethane (PU) coated surface of mango wood (Mangifera indica) with ammonia fumigation and an exposure towards sunlight was investigated

Study Design:  Thirty six wood samples of size 10.6 cm (length) C 7.62 cm (width) were prepared from 2.5 cm thick kiln dried mango wood (Mangifera indica). Specimens were divided into six groups, each group having 6 samples for the study.

Place and Duration of Study: The experiment was carried out in year 2016 at the Laboratory of Forest Product Division, Forest  Research Institute, Dehradun, Uttarakhand, India.

Methodology: All the samples were sanded with 80 grit size sand paper and coated with poly urethane.  Two chemicals were used for bleaching purpose like an aqueous solution of oxalic acid (H2C2O4) was prepared with 30% concentration (by mixing 42.9 g of the solute in 100 ml of hot water) and a commercially available Hydrogen peroxide (H2O2) was used as such (30%). For the purpose of bleaching, these chemicals were applied on to the sanded surfaces using brush at room temperature. The bleached sample surfaces were allowed to dry before proceeding to the next step. The PU (Poly Urethane) coated samples were treated with ammonia fumigation before and after bleached with the two chemicals. Ammonia fumigation was carried out in a fumigation chamber for 24 hours for all the samples (except T1).

Results: On exposure to natural sunlight for 60 hours, all the samples showed reduction in film thickness in PU coating but in a wide range of 2.8 % to 11.4%. The highest loss of coating thickness was shown by samples which were neither fumigated nor bleached. Among the fumigated samples, those bleached with oxalic acid resulted in high film thickness loss. Samples bleached with hydrogen peroxide after ammonia fumigation resulted in least film thickness reduction. Both ammonia fumigation and bleaching in general brought down the original gloss of poly urethane coating. The gloss value reduced as expected on exposure to sunlight. Bleaching by hydrogen peroxide prior to ammonia fumigation resulted in highest loss in gloss

    Conclusion: The un-fumigated and unbleached surface resulted in minimum gloss reduction due to long exposure to sunlight.

Published: July 2021

The breeding and production environments of pigs tend to be exposed to microbial contaminations and could portend a potential public health hazard if not well managed. This study investigated bacterial and fungal loads of commercial fresh and smoked pork in order to ascertain their wholesomeness. Total aerobic bacterial and fungal count were done on nutrient agar and potato dextrose agar respectively, while antimicrobial susceptibility test to selected commercial antibiotic discs carried out using Disk Diffusion Technique.  All the twenty samples (Fresh and Smoked) cultured yielded bacterial growth with a range of 2.2 - 9.0 × 104 CFU/g (smoked) to 1.0 – 6.3 × 106 CFU/g (fresh). On the other hand, the fungal loads ranges from 1.0 – 6.0 × 102 CFU/g(smoked) to 1.0 -5.0 × 104 CFU/g (fresh). The bacterial isolated and the ratios in fresh and smoked samples wereStaphylococcus aureus (6: 11), Escherichia coli (5: 8), Bacillus cereus (4: 7), Salmonella spp. (2: 3), Proteus spp. (0: 4), Enterobacter spp. (1: 2), Shigella spp. (0:2) and  Pseudomonas aeruginosa (1: 0), while their fungal counterpart included Aspergillus niger (4: 2), Aspergillus terreus (2; 2),Fusarium oxysporum(4: 0), Penicillium spp. (4: 2), Rhizopus spp. (3: 5), Mucor spp. (0: 4); Geotricum candidum (0: 2) and Microsporium spp. (0: 2).  Most of the S.aureus (> 58.8%) and P. aeruginosa (100%), and B. cereus (100%) demonstrated remarkable resistance to the majority of the tested antibiotics. These findings are of public health concern because most of the bacterial and fungal isolates have been implicated in foodborne infections. Hence, there is a need for stricter sanitary measures during the rearing and production to reduce the level of microbial contaminations.

Authors: Kumar R. V. Anil , Reddy P. Dwarakanadha
Published: July 2021

Drug use evaluation (DUE) is a systematic approach to study the utilization of marketed drugs. These studies are proved invaluable for policy makers to get inputs on the use of drugs so that they can review their strategies. In this prospective observational study, we have conducted a DUE of Acid suppressant drugs in Outpatient department (OPD) of a tertiary care teaching hospital in Kadapa, Andhra Pradesh. In the armamentarium of acid suppressants Proton pump inhibitors (PPIs) occupied a special space owing to their superiority to others like H2 receptor blockers. PPIs are in the market for the last 40 years and their safety and efficacy is impeccable till now. These are the most commonly used drugs and tend to be used for long-term to manage acidity problems. But unregulated usage of PPIs over long term could pose very significant health problems ranging from electrolyte imbalance to cognitive impairment.

Our study identified some issues in prescribing PPIs suggesting there is generous use of PPIs without considering their risks. And their safety also taken for granted, it appears.

Historically, natural products (NP’s) have played a significant role in drug discovery, not only in cancer and infectious diseases, but also in other therapeutic  areas including cardiovascular diseases and multiple sclerosis. Profit and loss, Partnerships and averages, natural products also present certain challenges for drug discovery, such as technical obstacles to screening, isolation, characterization and optimization, which added to decline in their search by the pharmaceutical industry from the 1990s onwards. In recent days the applications of molecular biological techniques have increased the availability of novel compounds that can be conveniently produced in bacteria or yeast or plant sources. In addition to this, combinational chemistry approaches are being based on natural product scaffolds to create screening libraries that closely resemble drug-like compounds. Employing these technologies gives us a chance to execute research in screening new molecules by means of a software and data base to ascertain natural products as a major source for drug discovery. It lastly directs to lead structure discovery. This review discusses plant based natural product drug discovery and how innovative technologies play a role in next generation drug discovery and highlights from the published literature on plants as sources of antiinflammatory agents.

Published: July 2021

Introduction: A public health program intends to improve the health care services in society to lessen the disease burden particularly in the case of non-infectious diseases. This research work investigates the knowledge, practice, and attitude of pharmacists in community health programs offered by the government concerning their demographic associates.

Methods: A cross-sectional survey from 75 registered pharmacists is conducted in Lahore, Pakistan to explore the role of pharmacists in public health programs by using a self-administered questionnaire from January 01, 2021, to January 15, 2021. The collected data is analyzed through frequencies, percentages, and a chi-square test of association.

Results: Most of the pharmacists were in favor that the disease burden can be reduced by indulging pharmacists in public health programs. Many pharmacists already working on public health issues were screening of the blood glucose, blood pressure, obesity, hypertension, dyslipidemia, and smoking cessation.

Conclusion: Like many other countries, Pakistan may also effectively accomplish its public health goals by offering training to the pharmacists and retaining them in public health programs at the pharmacy level.

Aims: The study aims to assess the incidence, causality, and severity of adverse transfusion reactions in patients transfused with blood or blood components at a secondary care referral hospital.

Study Design: A prospective observational study was conducted in the secondary care referral hospital located in rural settings of Anantapur district, Andhra Pradesh, India. The study was conducted for a period of six months from May 2019 to October 2019

Methodology: All the patients transfused with blood or blood components in the hospital located in Andhra Pradesh during those six months study period were included. The transfusion reactions were reported to the blood bank in the Adverse Transfusion Reaction Report Form (ATRRF). Descriptive statistics were used to represent the adverse transfusion reactions.

Results: From 2549 transfusions, 30 adverse transfusion reactions were reported (1.17%).Most of the reactions reported were febrile non-hemolytic transfusion reactions FNHTRs (73.3%) followed by allergic reactions (20.0%). Transfusion reactions were predominant in females 21 (70.0%) than males 9 (30.0%). Most of the reactions were confirmed/definite (46.6%) in causality assessment and moderate (63.3%) in severity assessment. The incidence of adverse transfusion reactions was found to be 1.17%.

Conclusion: The study concludes that there was a low incidence of adverse transfusion reactions indicating probably underreporting in the healthcare system. This would be due to lack of knowledge regarding importance of surveillance and reporting of adverse transfusion reactions by blood or blood components. There was a need to conduct continuous educational programs (CEP) on hemovigilance system towards healthcare providers to improve the reporting practice. The study provides insights about type of adverse transfusion reactions and their causality and severity. This data helps in motivating the healthcare staff to report ATRs and also to develop strategies to handle preventable ATRs.

Epistemologias para convivialidade ou Zumbificação
Authors: Baldraia Fernando
Published: July 2021

Inspirado no pensamento de Frantz Fanon, este texto é um diagnóstico do tempo presente encenado como uma “reação psicótica”, cujo esperado efeito colateral é fazer avançar a noção de convivialidade como um espaço de experimentação analítica, onde desigualdade e diferença compartilham a condição de isonomia conceitual. O experimento específico aqui realizado tenta atingir esse objetivo fundindo diferentes registros escriturais e explorando o repertório vernacular da junção brasileira de um Atlântico afro-indígena. Sua aposta analítica, a ideia de zumbificação, é o esboço de uma posição epistemológica cujo trabalho consiste em uma cinética de (pelo menos) três movimentos: 1) a posicionalidade necessária para fazer exigências políticas; 2) o decentramento necessário para atenuar os efeitos prejudiciais tanto do essencialismo (mesmo estratégico) como da inevitável reprodução de padrões hegemônicos excludentes; 3) o voluntarismo necessário para amplificar abordagens epistemológicas subalternizadas de modo que elas possam se tornar mais pervasivas. Epistemologies for Conviviality or “Zumbification”Inspired by Frantz Fanon’s thought, this paper is a diagnostic of the present time, enacted as a “psychotic reaction” that melts together different scriptural registers to advance the notion of conviviality as a space of analytical experimentation, where inequality and difference share the condition of conceptual isonomy. The experiment performed in this article tries to accomplish this goal by exploring the vernacular repertoire of the Brazilian junction of an afro-indigenous Atlantic. Its analytical idea, zumbification, is the sketch of an epistemological subject-position, whose labor consists in a kinesics of (at least) three movements: 1) the situatedness needed for making political demands; 2) the decenteredness necessary for attenuating the harmful effects of (even strategic) essentialism and the unavoidable reproduction of hegemonic exclusionary patterns; 3) the willfulness required for amplifying subalternized epistemological approaches, so that they may become more pervasive.Capoeira | Conviviality | Epistemology | Post-colonial theory | Zumbi

Published: July 2021

Este artigo analisa os impactos da presença dos grupos de línguas gbe na formação do léxico empregado no detalhamento das cicatrizes rituais da população africana presente no distrito diamantino da capitania de Minas Gerais em meados do século XVIII. O enfoque é dado sobre o processo histórico de difusão do termo “geja”, explorando tanto os seus significados ligados a padrões específicos de escarificações como o seu uso generalizado para marcas corporais africanas, independentemente da origem étnica. Examina-se a sua emergência como índice de uma cadeia mais ampla de significados atrelados à etnogênese jeje em um contexto de grande concentração urbana de povos da Costa da Mina.“With Two Gejas on Each Temple”: scarification and the process of visual translation in the jeje diaspora of 18th Century in Minas GeraisConsidering the visual culture of the African diaspora, this article analyzes the effects of the presence of Gbe language groups in the formation of the lexicon used in detailing the ritual scarification of the African population present in the diamond district of the captaincy of Minas Gerais in the eighteenth century. It focuses on the historical process of spreading the term geja, exploring both its meanings linked to specific patterns of scarification and its widespread use for African body markings in general. Its emergence is examined as an index of a broader chain of meanings connected to the Gbe ethnogenesis in a context of great urban concentration of people from Costa da Mina.Jeje Nation | African Diaspora | Gejas | Scarification

Published: July 2021

O autismo é um transtorno do desenvolvimento que normalmente costuma ser identificado na infância, persistindo na adolescência e na fase adulta. Pessoas com autismo são caracterizadas por déficits na comunicação, linguagem e comportamento, o que, invariavelmente, prejudica a sua interação social. Pesquisas em torno de Tecnologias da Informação e Comunicação (TIC), voltadas para o diagnóstico e o tratamento de pessoas com autismo, têm sido emergentes nos últimos anos. Dispositivos móveis, por exemplo, têm viabilizado diversas formas de acessibilidade e servido como ferramentas a indivíduos autistas com deficiências sensoriais, motoras, assim como aos que necessitam de comunicação aumentativa. Neste estudo, foram realizadas busca e análise em base de patentes e artigos científicos com o intuito de se obter um panorama das principais TICs que têm sido aplicadas a pessoas com autismo. Os resultados mostraram um crescimento substancial de trabalhos e tecnologias que podem proporcionar tratamentos alternativos para pessoas com autismo, totalizando 611 artigos científicos e 222 famílias de patentes.

Published: July 2021

A pesquisa possui como objetivo evidenciar quais práticas são realizadas pelos profissionais contábeis para obtenção e manutenção de novos clientes. Para isto, realizou-se uma pesquisa descritiva, tipo levantamento survey, e de abordagem quantitativa. A amostra final totalizou 165 respondentes. Os dados obtidos foram analisados por estatística descritiva. Os resultados revelam que os contadores utilizam algumas práticas de marketing para auxiliar na captação de novos clientes, porém ainda não fazem o uso total dessa ferramenta a seu favor. Os achados ainda apresentam que a qualidade dos serviços prestados é primordial para a permanência dos clientes no portfólio dos prestadores de serviços contábeis. Entretanto, estes serviços de qualidade não apresentam tamanha necessidade aos clientes a ponto de estarem dispostos a pagarem qualquer quantia. Por fim, esta pesquisa contrasta achados de estudos anteriores que relatam preocupação dos contadores quanto sua imagem, ao demonstrar a falta de utilização de técnicas para aquisição/manutenção de clientes.
Há associação entre experiência coletiva e produtividade na prestação de serviços mediadas por tempo, equivalência e custos?
Authors: Ferrari Mara Juliana , Borgert Altair
Published: July 2021

Esta pesquisa objetivou verificar se há associação entre experiência coletiva e produtividade na prestação de serviços. Caracterizado por um estudo de caso, predominantemente quantitativo e de natureza exploratória e descritiva, utilizou-se dados de produção por meio de equivalência, custos e tempo de permanência de integrantes de 11 equipes de trabalho de uma empresa prestadora de serviços de telecomunicações, ao longo de 24 meses. Para tanto, formulou-se duas hipóteses de pesquisa: hipótese nula, que não existe associação entre a variável Experiência e Produtividade ao longo do período considerando-se o tempo médio das equipes e, como hipótese alternativa, que as variáveis são associadas. Como resultado, por meio do teste Qui-quadrado obteve-se o valor de 3,7161, ao nível de significância de α = 0,05, com 4 graus de liberdade, e valor crítico de 9,48773 que representa a área caudal direita. Assim, como o valor Qui-quadrado está fora da área aceitável, não se pode rejeitar a hipótese nula, o que leva a conclusão de que os dados não mostram evidência de associação entre Experiência e Produtividade, para o caso estudado, cujas diferenças nas proporções podem ser explicadas por simples variações causais.

Physical relaxation for occupational stress in healthcare workers: A systematic review and network meta-analysis of randomized controlled trials
Authors: Zhang Michael , Murphy Brittany , Cabanilla Abegail , Yidi Christina
Published: July 2021

Objectives

Work related stress is a major occupational health problem that is associated with adverse effects on physical and mental health. Healthcare workers are particularly vulnerable in the era of COVID-19. Physical methods of stress relief such as yoga and massage therapy may reduce occupational stress. The objective of this systematic review and network meta-analysis is to determine the effects of yoga, massage therapy, progressive muscle relaxation, and stretching on alleviating stress and improving physical and mental health in healthcare workers.

Methods

Databases were searched for randomized controlled trials on the use of physical relaxation methods for occupational stress in healthcare workers with any duration of follow-up. Meta-analysis was performed for standard mean differences in stress measures from baseline between subjects undergoing relaxation vs non-intervention controls. Network meta-analysis was conducted to determine the best relaxation method.

Results

Fifteen trials representing 688 healthcare workers were identified. Random-effects meta-analysis shows that physical relaxation methods overall reduced measures of occupational stress at the longest duration of follow-up vs baseline compared to non-intervention controls (SMD −0.53; 95% CI [−0.74 to −0.33]; p < .00001). On network meta-analysis, only yoga alone (SMD −0.71; 95% CI [−1.01 to −0.41]) and massage therapy alone (SMD −0.43; 95% CI [−0.72 to −0.14]) were more effective than control, with yoga identified as the best method (p-score = .89).

Conclusion

Physical relaxation may help reduce occupational stress in healthcare workers. Yoga is particularly effective and offers the convenience of online delivery. Employers should consider implementing these methods into workplace wellness programs.
Increased Frailty in Individuals With Osteoarthritis and Rheumatoid Arthritis and the Influence of Comorbidity: An Analysis of the UK Biobank Cohort
Authors: Cook Michael J. , Verstappen Suzanne M. M. , Lunt Mark , O'Neill Terence W.
Published: July 2021

Objective

To determine the association between osteoarthritis (OA), rheumatoid arthritis (RA), and frailty and to determine whether comorbidities interact with OA and RA to further increase the likelihood of frailty.

Methods

Participants of the UK Biobank age 40–69 years at baseline were included. Demographic, lifestyle, and clinical data were collected at baseline and follow‐up in a subset. Frailty was assessed using a frailty index (FI) (continuous) and a modified frailty phenotype (robust, pre‐frail, frail). The association between RA and OA and frailty at baseline and follow‐up was assessed using multiple regression models. We looked at whether comorbidities, including cardiovascular disease, diabetes mellitus, chronic obstructive pulmonary disease, and depression interacted additively with OA and RA to increase the likelihood of frailty.

Results

In total, 457,561 participants contributed data. Those with (versus without) RA (n = 4,894) and OA (n = 35,884), respectively, were more likely to be frail (adjusted relative risk ratio 10.7 [95% confidence interval (95% CI) 9.7, 11.7] and 3.4 [95% CI 3.3, 3.6]) and were more likely to have a higher FI at baseline. There was evidence of additive interaction between RA, OA, and common comorbidities increasing the occurrence of prevalent frailty. Among 25,163 participants included in longitudinal analysis, patients with RA (n = 202) and OA (n = 1,811) at baseline had an increased adjusted frailty incidence rate ratio (2.8 [95% CI 1.7, 4.6] and 1.7 [95% CI 1.3, 2.1], respectively) and also a higher FI during follow‐up.

Conclusion

Individuals with RA and OA are more likely to have, or develop, frailty. Common comorbidities interact with OA and RA to further increase the likelihood of frailty.

Published: July 2021

Infrared (IR) photodetection is important for light communications, military, agriculture, and related fields. Organic transistors are investigated as photodetectors. However, due to their large band gap, most organic transistors can only respond to ultraviolet and visible light. Here high performance IR phototransistors with ternary semiconductors of organic donor/acceptor complex and semiconducting single‐walled carbon nanotubes (SWCNTs), without deep cooling requirements are developed. Due to both the ultralow intermolecular electronic transition energy of the complex and charge transport properties of SWCNTs, the phototransistor realizes broadband photodetection with photoresponse up to 2600 nm. Moreover, it exhibits outstanding performance under 2000 nm light with photoresponsivity of 2.75 × 106 A W−1, detectivity of 3.12 × 1014 Jones, external quantum efficiency over 108%, and high Iphoto/Idark ratio of 6.8 × 105. The device exhibits decent photoresponse to IR light even under ultra‐weak light intensity of 100 nW cm−2. The response of the phototransistor to blackbody irradiation is demonstrated, which is rarely reported for organic phototransistors. Interestingly, under visible light, the device can also be employed as synaptic devices, and important basic functions are realized. This strategy provides a new guide for developing high performance IR optoelectronics based on organic transistors.

Plasmonic photothermal therapy (PPTT) using gold nanoparticles (AuNPs) has shown great potential for use in selective tumor treatment, because the AuNPs can generate destructive heat preferentially upon irradiation. However, PPTT using AuNPs has not been added to practice, owing to insufficient heating methods and tissue temperature measurement techniques, leading to unreliable and inaccurate treatments. Because the photothermal properties of AuNPs vary with laser power, particle optical density, and tissue depth, the accurate prediction of heat generation is indispensable for clinical treatment. In this report, bioprinted 3D complex tissue constructs comprising processed gel obtained from porcine skin and human decellularized adipose tissue are presented for characterization of the photothermal properties of gold nanorods (AuNRs) having an aspect ratio of 3.7 irradiated by a near‐infrared laser. Moreover, an analytical function is suggested for achieving PPTT that can cause thermal damage selectively on early‐stage human breast cancer by regulating the heat generation of the AuNRs in the tissue.

Porous scaffolds are widely used in biomedical applications where pore size and morphology influence a range of biological processes, including mass transfer of solutes, cellular interactions and organization, immune responses, and tissue vascularization, as well as drug delivery from biomaterials. Ice templating, one of the most widely utilized techniques for the fabrication of porous materials, allows control over pore morphology by controlling ice formation in a suspension of solutes. By fine‐tuning freezing and solute parameters, ice templating can be used to incorporate pores with tunable morphological features into a wide range of materials using a simple, accessible, and scalable process. While soft matter is widely ice templated for biomedical applications and includes commercial and clinical products, the principles underpinning its ice templating are not reviewed as well as their inorganic counterparts. This review describes and critically evaluates fundamental principles, fabrication and characterization approaches, and biomedical applications of ice templating in polymer‐based biomaterials. It describes the utility of porous scaffolds in biomedical applications, highlighting biological mechanisms impacted by pore features, outlines the physical and thermodynamic mechanisms underpinning ice templating, describes common fabrication setups, critically evaluates complexities of ice templating specific to polymers, and discusses future directions in this field.
Changing Gears – DBS For Dopaminergic Desensitization in Parkinson's Disease?

Published: July 2021

In Parkinson's disease, both motor and neuropsychiatric complications unfold as a consequence of both incremental striatal dopaminergic denervation and intensifying long‐term dopaminergic treatment. Together, this leads to ‘dopaminergic sensitization’ steadily increasing motor and behavioral responses to dopaminergic medication that result in the detrimental sequalae of long‐term dopaminergic treatment. We review the clinical presentations of ‘dopaminergic sensitization’, including rebound off and dyskinesia in the motor domain, and neuropsychiatric fluctuations and behavioral addictions with impulse control disorders and dopamine dysregulation syndrome in the neuropsychiatric domain. We summarize state‐of‐the‐art deep brain stimulation, and show that STN‐DBS allows dopaminergic medication to be tapered, thus supporting dopaminergic desensitization. In this framework, we develop our integrated debatable viewpoint of “changing gears”, that is we suggest rethinking earlier use of subthalamic nucleus deep brain stimulation, when the first clinical signs of dopaminergic motor or neuropsychiatric complications emerge over the steadily progressive disease course. In this sense, subthalamic deep brain stimulation may help reduce longitudinal motor and neuropsychiatric symptom expression – importantly, not by neuroprotection but by supporting dopaminergic desensitization through postoperative medication reduction. Therefore, we suggest considering STN‐DBS early enough before patients encounter potentially irreversible psychosocial consequences of dopaminergic complications, but importantly not before a patient shows first clinical signs of dopaminergic complications. We propose to consider neuropsychiatric dopaminergic complications as a new inclusion criterion in addition to established motor criteria, but this concept will require validation in future clinical trials.

Bell‐GHZ Measurement‐Device‐Independent Quantum Key Distribution
Authors: Castañeda Valle David , Quezada Luis Fernando , Dong Shi‐Hai
Published: July 2021

In this work, a one‐sided measurement‐device‐independent quantum key distribution protocol that uses Bell and Greenberger–Horne–Zeilinger (GHZ) states is proposed. The protocol considers three parties: Alice and Bob, who will share the key at the end of the protocol; and Charlie, who plays the role of facilitating the key distribution without having access to the key itself. Alice and Charlie are trusted users, while Bob is uncharacterized. The protocol is asymmetrical, meaning that Alice sends one qubit while Bob sends two; this allows Bob to identify himself via a previously assigned ID; if this authentication fails, the key distribution also will.

Published: July 2021

Two new glycolated semiconducting polymers PgBT(F)2gT and PgBT(F)2gTT of differing backbone curvatures were designed and synthesised for application as p‐type accumulation mode organic electrochemical transistor (OECT) materials. Both polymers demonstrated stable and reversible oxidation, accessible within the aqueous electrochemical window, to generate polaronic charge carriers. OECTs fabricated from PgBT(F)2gT featuring a curved backbone geometry attained a higher volumetric capacitance of 170 F cm−3. However, PgBT(F)2gTT with a linear backbone displayed overall superior OECT performance with a normalised peak transconductance of 3.00×104 mS cm−1, owing to its enhanced order, expediting the charge mobility to 0.931 cm2 V−1 s−1.

Enantioselective construction of molecules bearing multiple stereogenic elements is increasingly related to the synthesis of enantiopure natural products, pharmaceuticals, and functional materials. However, atom‐economical and enantioselective approaches to install multiple stereogenic elements in a small molecular template by limited chemical transformation remain challenging. We describe an organocatalytic enantioselective method for the preparation of polychiral molecules bearing four types of stereogenic elements in fused azepines via vinylidene ortho‐quinone methide (VQM)‐mediated intramolecular electrophilic aromatic substitution. This method was proved robust with a wide range of substrate scope (46–92 % yield), with excellent diastereoselectivity (>20:1 dr) and enantioselectivity achieved (up to 97 % ee). Optical properties and Ru3+‐induced fluorescence responses of these compounds suggest their potential applications in optoelectronic materials and heavy metal ion detection.

In view of rising ecological awareness, materials development is primarily aimed at improving the performance and efficiency of innovative and more elaborate materials. However, a materials performance figure of merit should include essential aspects of materials: environmental impact, economic constraints, technical feasibility, etc. Thus, we promote the inclusion of sustainability criteria already during the materials design process. With such a holistic design approach, new products may be more likely to meet the circular economy requirements than when traditional development strategies are pursued. Using catalysts for water electrolysis as an example, we present a modelling method based on experimental data to holistically evaluate processes.

Development of a high‐efficient heterogeneous catalyst is very important for the preparation of organic azides compounds in modern synthetic chemistry. Acidic mesoporous Beta, mesoporous ZSM‐5, and mesopore‐free ZSM‐5 zeolite were used as supports for the preparation of Fe (Fe/Beta‐M, Fe/ZSM‐5‐M, & Fe/ZSM‐5) catalysts and were applied the carboazidation of N‐arylacrylamides with azidotrimethylsilane. The influence of pore size, acidities, and metal of the catalysts on reaction activity was investigated by X‐ray powder diffraction, N2 adsorption isotherm, scanning electron microscope, transmission electron microscopy, X‐ray photoelectron spectroscopic, and temperature‐programmed desorption of ammonia. The characterization and activity results show that the acidity, Fe species (Fe2+ and Fe3+) and mesoporosity in the Fe/Beta‐M catalyst jointly contribute to this reaction, and Fe/Beta‐M catalyst shows higher catalytic activity than Fe/ZSM‐5‐M, Fe/ZSM‐5, and FeCl3 catalysts.

Monodisperse composite microspheres were prepared of zirconia and urea formaldehyde resin having an average particle size of 2.2 μm. Their surface was modified by silane coupling agent and styrene, and then sulfuric acid assisted with silver sulfate to form solid sulfonic acid based ion‐exchange catalyst (namely, ZrO2‐SIEC) for the alkylation of 2,4/2,5‐xylenol mixture. The selectivities of catalyst ZrO2‐SIEC to produce 6‐2,4‐xylenol and 4‐2,5‐xylenol were found to be 98.9% and 97.9%, with yields of 98.6% and 80.9%, respectively. The optimized reaction conditions were identified including temperature (80°C), catalyst dosage (9%) and reaction time (180 min). In addition, catalyst ZrO2‐SIEC showed good reusability for maintaining stable catalytic performance over 25 cycles of reuse, attributed to its stable mechanical, thermal and chemical properties. Comparison with other four catalysts demonstrated good performance of ZrO2‐SIEC in terms of catalytic activity, operating conditions, separation from products, and environmental friendliness.

In this work, four aliphatic chain extenders, hexanediol (HDO), hexane diamine (HDA), cystamine (CY), and cystine dimethyl ester (CDE), were chosen to synthesize four kinds of polyurethane and poly(urethane‐urea)s (PUs), respectively. HDO extended polyurethanes, HDA extended poly(urethane‐urea), CY extended poly(urethane‐urea), and CDE extended poly(urethane‐urea) were denoted as OPU, APU, CPU, and SPU, respectively. The effect of chain extender type on microphase structure and performance of four PUs was investigated. Our research showed that mechanical strength increased in the following order: OPU < SPU < CPU < APU, and self‐healing performance increased in the opposite direction. This result is attributed to the increasing degree of microphase separation: OPU < SPU < CPU < APU. The optimal sample SPU has not only excellent mechanical properties (tensile strength of 27.1 MPa and elongation at break of 397.7%), but also exhibits superior self‐healing performance (self‐healing efficiencies of 95.3% and 93.5% based on tensile strength and elongation at break). The moderate degree of microphase separation between the soft segments and the hard segments, the introduction of disulfide bonds and low degree of hydrogen bonding are responsible for preparing a polyurethane or poly(urethane‐urea) system with high mechanical strength and excellent self‐healing performance simultaneously. This work provides useful information for us to develop self‐healing polyurethane or poly(urethane‐urea) materials in the future.
