O estudo tem como objetivo geral identificar as diferentes etapas que envolveram o processo de salvaguarda de documentos, sua potencialidade como documento histórico e para as discussões referentes à História da Educação. De modo específico, esse estudo centrou-se no processo de arquivamento dos documentos do escritor Gaúcho Clodomir Vianna Moog, guardados em nível privado, até sua disponibilização no arquivo do Memorial Jesuíta, localizado na Biblioteca Central da Universidade do Vale do Rio dos Sinos – Unisinos. O suporte metodológico abrangeu a História Oral e a análise documental histórica. De acordo com os pressupostos da história cultural e da História da Cultura Escrita, foi possível compreender que os arquivos pessoais são fontes históricas de fundamental importância para o fornecimento de subsídios e para problematização de tempos, espaços, sujeitos e seus modos de inserção na sociedade. O trabalho arquivístico desenvolvido nos documentos pessoais deve ser orientado pela gênese dos artefatos culturais. Além disso, entende-se que a custódia do patrimônio documental pessoal deve ser precedida do interesse de disponibilização para pesquisas, e o acesso aos pesquisadores deve ser facilitado e mais bem compreendido. A partir do estudo, foi possível vislumbrar que o campo de pesquisas em arquivos pessoais vem se alargando no que se refere ao interesse de distintas áreas do conhecimento sobre arquivos pessoais. Assim, alguns entendimentos acerca do seu aspecto privado se ampliaram, e a fonte documental de natureza pessoal pode fornecer subsídios indispensáveis para a historiografia.

Pretende-se analisar de que forma diferentes tipos de documentos pessoais, guardados ao longo de anos pelas suas proprietárias, podem ser usados como fontes em investigação em educação. De uma primeira parte, na qual se contextualiza o tema dos arquivos pessoais do ponto de vista teórico, passa-se a uma descrição dos arquivos em análise, sublinhando os obstáculos e desafios que se colocam. Numa última parte, reflete-se sobre os constrangimentos e possibilidades de utilização dos arquivos pessoais em História da Educação.
coleção para guardar e ensinar
Authors: Vasconcelos Maria Celi Chaves
Published: December 2022

O artigo em pauta tem como objetivo central analisar aspectos presentes nas anotações do caderno de receitas da viscondessa de Arcozelo, como um artefato que faz parte dos arquivos privados femininos, em especial, das mulheres oitocentistas, cujo cotidiano voltado para casa e família revestia-se de poucas possibilidades de escrita íntimas, notadamente aquelas caracterizadas como narrativas pessoais. Em um plano mais específico, busca-se verificar como o caderno de receitas pode ser considerado também um modo de educação, por meio dos conhecimentos e das práticas que pretendia guardar e preservar para ensinar a outras mulheres. A fonte principal do estudo é o caderno de receitas, analisado como um documento que contém traços de intimidade e cuidado, alimentado em um arquivo pessoal e elaborado por sua titular como uma coleção, a partir da inter-relação com outras mulheres que faziam parte das sociabilidades geracionais do seu tempo. Os procedimentos metodológicos remetem a uma pesquisa essencialmente documental, que confronta esse manuscrito com outros produzidos pela mesma autora, como o seu diário, além da bibliografia referente ao cotidiano feminino de mulheres letradas no século XIX. Ao final, conclui-se com a apreciação desse arquivo pessoal como um importante testemunho da cultura material e da vida cotidiana com seus usos e costumes nas casas-grandes oitocentistas.

PURPOSE: Financial ecologies (FEs) are place-based governance forms of financial services provision, currently undergoing a transformation through financial technologies (Fintech). The idea of FEs is socially and economically relevant, since they reach toward underserved or excluded market segments and intermediate for territorial development across industries and sectors of private and public entities. At the same time, the FE remains at the early stage of conceptualization and empirical corroborations, in particular regarding how Fintech affects its core elements and related policy implications. In response to the theoretical and practical relevance, and early stage of theorizing the recent Fintech developments in the FE, this article aims to identify how Fintech frame FEs and to propose the resulting conceptual and policy-related implications. METHODOLOGY: To frame the FE concept, we used the methodological lens of construct clarity principles and the concept reconstruction. The research method includes a systematic literature review of 48 publications selected from Scopus and WoS databases. FINDINGS: We have analyzed the concept of FE according to its major elements and related concepts. The FE remains at the intersection of other outcome-oriented ecosystems that focus on territories, but it can also be treated as an independent phenomenon and research object. The idea of FE has been shaped by Fintech-driven developments in all its constituent elements with conceptual and policy consequences formulated as a set of propositions. IMPLICATIONS: The findings are relevant for future theory development and empirical corroborations of the FE. They can also enhance the integration of research communities of practice to accumulate knowledge. Despite standardization brought about by technological innovations, the availability, usefulness, and effects of financial ecosystems depend on the multiscalar spatial contexts that differ in socio-economic and institutional dimensions. ORIGINALITY AND VALUE: First, the article frames the understanding of FE as financial services governance based on technological advancements and focused on territorial projects and communities. Second, the FE concept was clarified according to major properties and relationships to other adjacent ideas of spatial networking for socioeconomic development. Third, propositions and research areas were formulated for further investigations.
Modeling the response of Japanese quail to arginine intake

Published: December 2022

Background

Understanding how Japanese quails respond to arginine intake has been an objective that previous studies have not fulfilled. The main responses to be quantified include the arginine requirement for maintenance (mg/kg0.67) and egg mass production (mg/g). Quantifying maintenance and production relationships are essential steps for predicting animal response. The current study aimed to describe how quails respond to arginine intake and determine arginine requirements for maintenance and egg production in Japanese quails.

Methods

The experiment was carried out in a completely randomized design, with seven treatments and seven replicates with individual birds as experimental units. The arginine levels were: 2.43, 3.64, 4.85, 6.07, 9.07, 12.13, and 14.56 g/kg. The experiment lasted for eight weeks. The variables analyzed were daily arginine intake, daily arginine deposition in eggs, and body weight. The data were analyzed using a mixed model, with the experimental unit being the random effect and the experimental levels of arginine as a fixed effect. When the effect of arginine levels was detected (P ≤ 0.05), saturation kinetics and an exponential model with four parameters (monomolecular) were adopted. ANOVA results indicated that dietary arginine levels significantly affected (P < 0.01) the analyzed variables. The formulation strategy of the experimental diets allowed amplitude in the dietary arginine levels, and according to bird responses, arginine was the limiting nutrient.

Results

The arginine requirement for body weight maintenance (BW0.67) was estimated to be 90 mg/kg BW0.67 by the monomolecular function. The requirement for egg mass (EM) production was estimated to be 25 mg/g per egg. A factorial model was parameterized as follows: daily arginine intake mg/bird = 90 × BW0.67 + 25 × EM ± 12 mg. The model was applied to data obtained from literature, and the resultant error was within the expected limit of 12 mg. The recommended daily arginine intake for the daily production of 11 g of egg and 180 g of BW was determined to be 304 mg/bird. The current study provides procedures that researchers can easily adopt.

Authors: Scarpati Renato Nascimento , Correia Rogério Dias
Published: December 2022

Este estudo objetivou analisar a influência do número de licitantes no desconto obtido em licitações de obras e serviços de engenharia e outros fatores capazes de influenciar na obtenção do desconto. Também se pesquisou a influência das condições restritivas nos descontos ofertados e as possíveis consequências desse desconto na execução dos contratos. Foram realizadas regressões simples e múltiplas no modelo Tobit e demais estatísticas. Os resultados indicam que o número de licitantes é o fator que mais tem influência no desconto obtido. Também ficou evidenciado que as demais condições restritivas tendem a aparecer mais em licitações com baixos descontos. Por fim, identificou-se que os descontos maiores não levam necessariamente à maior tendência de rescisão ou de aditivos, de prazo e de valores, nos contratos em execução.

Authors: Akhtar Sameera , Akhtar Sufhia , Ali Shoket , Tabassum Nazia
Published: December 2022

Introduction: Hepatitis B Virus (HBV) causes most frequent chronic liver disease of infectious origin in human beings worldwide, with more than 600,000 deaths caused by end-stage liver disease complications per year. The most used test for identifying acute HBV infections and carriers is the detection of HBsAg. Immunochromatography assays have been suggested for routine use in clinical microbiology laboratories for the detection of HBsAg since they are easy to use, affordable, don’t need specialised equipment, and are straightforward to run. Compared to commercially available HEPA card kit for the detection of the same markers, Enzyme Linked Immunosorbent Assay (ELISA) was shown to be more sensitive for the detection of HBsAg. This study is first of its kind in District Doda, Jammu and Kashmir, India. Aim: To know the burden of HBV in a tertiary Care Hospital, Government Medical College, Doda using HEPA card kit and ELISA method. Materials and Methods: The present hospital-based crosssectional study was carried out in the Department of Microbiology, Government Medical College and Hospital, Doda Jammu and Kashmir, India during the period from January 2020 to December 2020. The study comprised blood samples from all age groups referred by clinical departments for testing HBsAg. Tests were performed using an immunochromatographic technique (Hepa Card Diagnostic enterprises) for the qualitative detection of HBsAg, and results were interpreted in accordance with the manufacturer’s guidelines. The collected data was analysed in microsoft excel sheet using Chi-square test to know the burden of HBV infection. Results: Among total number of 5,448 samples tested, 50 (0.92%) were positive for HBsAg which comes under low epidemicity (<2%) as per World Health Organisation (WHO) guidelines. The number of positive females and males were 30 (0.84%) and 20 (1.07%), respectively. Females were predominate over males and majority of the positive patients (N=29) were younger than 40 years though prevalance (2.1%) was higher in age group above 40 years. All samples which shows positive by rapid test were also shown positive by ELISA test. Conclusion: Overall prevalence of HBV was 0.92% which comes under low epidemicity (<2%) as per WHO guidelines. It can be an alternate option for community based studies and also helps to improve the public health and to prevent the spreading of disease in the local population.
Tibial Guidewire Insertion Timing- Does it Affect the Functional Outcome in Arthroscopic Anterior Cruciate Ligament Reconstruction? A Prospective Longitudinal Study
Authors: Nidhin TS , Shibu R , Roy AS Shyam
Published: December 2022

Introduction: Tibial fixation site of graft in arthroscopic Anterior Cruciate Ligament (ACL) reconstruction has an effect on anterior displacement and internal rotation of the tibia. The position of the interference screw determines the final orientation of the graft. The screw position in turn depends on the position of the tibial guidewire. The tibial guidewire can be placed before introducing the graft or after the graft placement. There are no studies in the literature comparing the outcome of tibial guidewire placement timing in arthroscopic ACL reconstruction. Aim: To compare the functional outcome of arthroscopic ACL reconstruction, with placing the tibial guidewire before and after graft passage. Materials and Methods: This prospective longitudinal study was conducted at Government Medical College, Thiruvananthapuram, India, from February 2020 to January 2021, among patients undergoing arthroscopic ACL reconstruction. A total of 84 patients with an isolated ACL tear, who underwent arthroscopic ACL reconstructionwere followedup for a minimum period of nine months. Two groups were studied, each with 42 patients. In group 1, the tibial guidewire was placed posterolaterally in the tibial tunnel and then the graft was pulled through femoral and tibial tunnels. In group 2, the guidewire was placed after the graft was passed through femoral and tibial tunnels. Functional outcomes were evaluated with International Knee Documentation Committee (IKDC) and Lysholm knee scores after nine months. Statistical analyses were carried out using Statistical Package for Social Sciences (SPSS) statistics version 22.0. Results: The median age of the study subjects were 27 (22;35) years. Fifty nine (70.2%) patients were males. Forty eight (57.1%) patients had left-sided injuries. The majority of injuries (n= 58, 69%) were due to sports injuries. In 14 patients (16.7%), the mode of injury was due to road traffic accidents and in 12 patients (14.3%) it was due to a fall. In the majority of the cases (n=50, 59.5%), the duration between injury and ACL reconstruction was 3 months. The mean IKDC subjective score of group 1 was 86±5.51 and that of group 2 was 81.9±6.64; (p-value=0.003). The mean Lysholm score of group 1 was 84.9±8.73 and that of group 2 was 79.6±9.56; (p-value=0.009). Conclusion: Arthroscopic ACL reconstruction placing the tibial guidewire posterolaterally prior to graft passage has got a better functional outcome compared to placing the guidewire after passing the graft. Prior placement of guidewire before graft ensures the posterolateral position of the interference screw at the tibial tunnel and increases the graft obliquity

Ficus capensis (farin baure) has wide application in traditional medicine especially in the Northan part of Nigeria in the treatment and management of diarrhoea and digestive distress. This is attributed to the presence of many biologically active compounds in their different parts. In this study, stem bark of F. capensis was extracted with four (4) solvents of different polarities ranging from non-polar, moderately polar to polar. Qualitative phytochemical screening of these extracts was conducted using standard laboratory procedures. The results revealed that only alkaloids, glycosides and carbohydrates were detected from the n-hexane (non-polar) extract of F. capensis while the chloroform and ethyl acetate (moderately polar solvents) and methanol (polar solvent) extracts showed the presence of tannins, saponins, alkaloids, carbohydrates, glycosides, flavonoids and proteins. But anthraquinones were not detected in all the extracts.

Antimicrobial properties of the extracts were evaluated using clinical isolates of four different bacteria and fungi each. Different concentration of extracts was prepared and activity was measured using zone of inhibition in millimetres (mm). Methanol extracts showed activities against E. coli with the zone of inhibition 10 mm, 11 mm, 12 mm and 14 mm; B. subtilis with the zone of inhibition 10 mm, 11 mm, 13 mm and 15 mm all for 10, 20, 25 and 30% concentration of extracts respectively. Chloroform and ethyl acetate extracts showed antimicrobial activities against S. aureus (12 mm, 14 mm), E. coli (12 mm, 14 mm), P. aeruginosa (14 mm, 12 mm) and B. subtilis (12 mm, 16 mm) respectively for 20% concentration of the extracts. The methanol and ethyl acetate extracts showed considerable antifungal activities against Aspergillus flavus and Aspergillus fungatus. But the n-hexane extract did not show any reasonable antibacterial and no antifungal activities.

Published: December 2022

The fish composition in the upper course of Otamiri River was investigated for six months between April and September 2019, to determine the related abundance and diversity of fish species in the river. Fish species were collected weekly using fishing gears from three sampling stations which were purposefully selected. Sixteen species of fish belonging to nine (9) fish families were recorded. Among the families, Cichlidae recorded the most abundant at 83.3%, followed by Notopteridae (6.7%), Alestidae (4.2%) and Clarotidae (3.8%). Others include: Hepsidae (0.4%), and Cyprinidae (0.2%), while Channidae and Gymnarchidae were recorded as the least abundance with values of 0.1% each. The study showed that Sarotherodon melanotheron has the highest diversity with the value recorded 3.18, followed by Coptodon zilli having the value 3.09 respectively. It also shows that Barbus occidentalis with the value 0.69, followed by Coptodon dageti with value 1.01 has the least diversity. The study also showed that Pelmatopia mariae with value 0.99 was highly distributed. From the study, the fish species harvested from this water body have low population. This has great implication on the stock in the fishery and can also act as an indicator of over-exploitation of this species. Regular and detailed study on species composition of this water body should be encouraged for the sustainable utilization of its resources, also a proper restocking of Otamiri water body should be embarked on by Imo State government to enhance fresh water fish availability in the State and its environs.

Published: December 2022

Loss of soil fertility through loss of soil organic matter, leaching of nutrients, loss of the nutrient-laden topsoil, changes in soil-pH, reduction in cation exchange capacity, salinization, water logging and other forms of soil degradation are major problems associated with agricultural productivity in the oil producing areas of Nigeria. This analysis investigated some selected physico-chemical properties of wetland soils affected by crude oil spillage in Bodo city in the Niger Delta region of Nigeria. Field reconnaissance survey using a handheld Geographic Positioning system (GPS) and survey technique involving random sampling, was used in siting soil profile pits. The unpolluted samples were collected 50 meters away from the polluted site but in the same geographic region and was used as control site. Soil samples were collected based on degree of horizon differentiation and analyzed using routine and special analytical techniques. Soil data were subjected to analysis of variance using Genstat program. Result shows that soil physical properties of the polluted site: moisture content, soil bulk density, and soil texture were highly significant (p=0.01 and 0.05) when compared to the unpolluted site while some chemical soil properties analysed especially soil pH, organic matter, carbon-nitrogen ratio, available phosphorus were affected by crude oil spillage. Results from this study affirm that crude oil can have detrimental effect on soil physico-chemical properties, which implies low soil fertility and thereby affect crop production and increase food insecurity within the study site. Further studies involving more edaphic properties, biotoxic metals and their bioaccessibility in crops growing on waterside affected by crude oil spill will surely enhance knowledge and management of the these highly industrially influenced soils. Also, international and national oil and gas companies should carry out their activities with international best practice.

Published: December 2022

Introdução: a desnutrição representa um problema clínico-nutricional frequente em pacientes hospitalizados, sendo que a detecção precoce do risco nutricional torna-se fundamental, pois possibilita à equipe multidisciplinar o início imediato de uma conduta dietética adequada, minimizando o sinergismo entre a desnutrição e os demais fatores clínicos. Objetivo: determinar o risco nutricional, associando com o estado nutricional, estilo de vida e variáveis clínicas de hospitalização de pacientes internados pelo SUS, comparando tais condições entre os sexos. Metodologia: trata-se de estudo transversal. Para avaliação do risco nutricional dos pacientes hospitalizados foi utilizado o protocolo de triagem nutricional Nutricional Risk Screening (NRS) 2002, além disso foram coletados dados antropométricos, clínicos, sociodemográficos e dietéticos para comparação com o risco nutricional. Resultados: a amostra foi composta por 100 pacientes, sendo 50% adultos e 50% idosos, com média de idade de 56,11±19 anos, sendo a maioria do sexo masculino (51%). O risco nutricional esteve presente em 34% dos pacientes avaliados, sendo 58,8% no sexo feminino e 41,2% no sexo masculino. Não houve diferença das demais variáveis quando comparadas entre os sexos (p>0,05). A maior prevalência de risco observada foi em idosos (27%). Conclusão: o risco nutricional obteve maior prevalência nos pacientes idosos, porém não houve diferença entre os sexos. Sabe-se que a presença de comorbidades e uma inadequada aceitação da dieta por parte dos mesmos pode levar a uma piora significativa do estado nutricional.

Doença arterial obstrutiva periférica em pacientes com insuficiência renal crônica dialítica na região de Toledo - Paraná
Authors: Ramos Marianne Ariely Andretta , Litchteneker Karina , Santana Taiane Costa , Unser Vinícius
Published: December 2022

Introdução: a doença arterial obstrutiva periférica (DAOP) tem alta prevalência na população em geral e está associada a elevado risco de eventos cardiovasculares. O índice tornozelo-braquial (ITB), é um exame simples e não invasivo, com alta sensibilidade e especificidade no diagnóstico de DAOP. A patologia pode estar associada a diversos fatores de risco, entre eles a doença renal crônica terminal. Contudo, os dados que avaliam sua prevalência e fatores de risco na população de doentes renais crônicos são escassos. Objetivos: Determinar a prevalência e os fatores de risco da doença arterial obstrutiva periférica em pacientes com insuficiência renal crônica dialítica. Metodologia: trata-se de um estudo transversal, que analisou 117 pacientes com doença renal dialítica. Foram avaliados através de um questionário para identificação dos fatores de risco e submetidos ao teste do ITB, sendo considerado diagnóstico de DAOP quando ITB <0,9. Resultados: o presente estudo evidenciou uma prevalência de DAOP em 11% dos pacientes, sendo 10 classificados como DAOP leve e 3 como moderada. Não foram encontrados pacientes com DAOP severa. Entretanto, 54 pacientes (46,2%) apresentaram rigidez de parede vascular. Assim, foi possível verificar que 67 (57,3%) pacientes apresentaram o ITB alterado. Conclusão: a alta prevalência de DAOP em pacientes com doença renal crônica dialítica foi análoga ao encontrado poroutros autores. É importante ressaltar que pacientes com ITB > 1,3 podem gerar resultados falsos-negativos no diagnóstico de DAOP. Devido a isso, a prevalência pode estar subestimada, o que sugere que o ITB nesses pacientes deve ser avaliado com mais atenção.

Authors: Baman Jayson R. , Medhekar Ankit N. , Malaisrie S. Chris , McCarthy Patrick , Davidson Charles J. , Bonow Robert O.
Published: December 2022

Importance

The management of aortic valve disease, including aortic stenosis and aortic regurgitation (AR), in younger adult patients (age <65 years) is complex, and the optimal strategy is often unclear, contingent on multiple anatomic and holistic factors.

Observations

Traditional surgical approaches carry significant considerations, including compulsory lifelong anticoagulation for patients who receive a mechanical aortic valve replacement (AVR) and the risk of structural valvular deterioration and need for subsequent valve intervention in those who receive a bioprosthetic AVR. These factors are magnified in young adults who are considering pregnancy, for whom issues of anticoagulation and valve longevity are heightened. The Ross procedure has emerged as a promising alternative; however, its adoption is limited to highly specialized centers. Valve repair is an option for selected patients with AR. These treatment options offer varying degrees of durability and are associated with different risks and complications, especially for younger adult patients. Patient-centered care from a multidisciplinary valve team allows for discussion of the optimal timing of intervention and the advantages and disadvantages of the various treatment options.

Conclusions and Relevance

The management of severe aortic valve disease in adults younger than 65 years is complex, and there are numerous considerations with each management decision. While mechanical AVR and bioprosthetic AVR have historically been the standards of care, other options are emerging for selected patients but are not yet generalizable beyond specialized surgical centers. A detailed discussion by members of the multidisciplinary heart team and the patient is an integral part of the shared decision-making process.

Importance

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis. Few studies have evaluated the mortality outcomes of patients with PG.

Objective

To investigate all-cause and cause-specific mortality in patients with PG.

Design, Setting, and Participants

This retrospective population-based cohort study used data from the National Health Insurance Service database of Korea and the National Death Registry of Korea from patients with incident PG (≥3 documented visits with an International Statistical Classification of Diseases and Related Health Problems, Tenth Revision [ICD-10] code of L88) during January 2003 to December 2019. For comparison, a 1:20 cohort of age-, sex-, insurance type–, and income level–matched controls without any documented visit with an ICD-10 code of L88 during the entire observation was included.

Exposures

Pyoderma gangrenosum.

Main Outcomes and Measures

The participants were observed from the index date to their death, emigration, or the end of the observation period to investigate all-cause and cause-specific mortality during the 17-year study period.

Results

In total, 3386 patients with PG (1450 women [42.8%]; mean [SD] age, 57.8 [16.4] years) and 67 720 controls (29 000 women [42.8%]; mean [SD] age, 57.8 [16.3] years) were analyzed. All-cause mortality risk was greater in patients with PG than in controls (adjusted hazard ratio [aHR], 2.122; 95% CI, 1.971-2.285) after adjustment for smoking, drinking, body mass index, and comorbidities. Patients experienced greater mortality of infectious disease (aHR, 3.855; 95% CI, 2.640-5.628), neoplasm (aHR, 1.618; 95% CI, 1.363-1.920), hematologic disease (aHR, 12.298; 95% CI, 3.904-38.734), endocrine disease (aHR, 6.322; 95% CI, 5.026-7.953), neurologic disease (aHR, 2.039; 95% CI, 1.337-3.109), cardiovascular disease (aHR, 1.979; 95% CI, 1.645-2.382), respiratory disease (aHR, 1.757; 95% CI, 1.365-2.263), gastrointestinal disease (aHR, 2.278; 95% CI, 1.522-3.408), connective tissue disease (aHR, 8.685; 95% CI, 4.963-15.199), and kidney/urogenital disease (aHR, 3.617; 95% CI, 2.488-5.259) than controls. Compared with idiopathic PG (aHR, 2.062; 95% CI, 1.897-2.241), PG that was associated with solid organ cancer (aHR, 2.313; 95% CI, 1.956-2.737) and hematologic cancer (aHR, 8.330; 95% CI, 5.473-12.679) showed greater mortality, whereas PG that was associated with inflammatory bowel diseases showed a slightly better prognosis (aHR, 1.742; 95% CI, 0.964-3.148).

Conclusions and Relevance

The results of this cohort study suggest that patients with PG had a higher all-cause and cause-specific mortality risk than the general population.

Published: December 2022

Metal–organic frameworks (MOFs) have emerged as ideal multifunctional platforms for renewable hydrogen (H2) energy applications owing to their tunable chemical compositions and structures and high porosity. Their advanced component species and porous structure contribute greatly to the enhanced activity, electrical conductivity, photo response, charge‐hole separation efficiency, and structural stability of MOF materials, which are promising for practical H2economy. In this review, we mainly introduce design strategies for the enhancement of electro‐/photochemical behaviors or adsorption performance of porous MOF materials for H2production, storage, and utilization from compositional perspective. Following these engineering strategies, the correlation between composition and property‐structure‐performance of pristine MOFs and their composite with advanced components is illustrated. Finally, challenges and directions of future development of related MOFs and MOF composites for H2economy are provided.

Alkaline water electrolysis is a commercially viable technology for green H2 production using renewable electricity from intermittent solar or wind energy, but very few non‐noble bifunctional catalysts simultaneously exhibit superb catalytic efficiency and stability at large current densities for hydrogen and oxygen evolution reactions (HER and OER, respectively), especially for iron‐based catalysts. Given that iron is the most abundant and least expensive transition metal, iron‐based compounds are very attractive low‐cost targets as active electrocatalysts for bifunctional water splitting with large‐current durability. Herein, the in situ construction of a self‐supported Fe2P/Co2N porous heterostructure arrays possessing superb bifunctional catalytic activity in base is reported, featured by low overpotentials of 131 and 283 mV to attain a current density of 500 mA cm−2 for HER and OER, respectively, outperforming most of non‐noble bifunctional electrocatalysts reported hitherto. Particularly, this hybrid catalyst also displays an excellent overall water splitting activity, requiring low voltages of 1.561 and 1.663 V to attain 100 and 500 mA cm−2 with excellent durability in 1 m KOH, respectively. Most importantly, the catalyst is stable for >120 h, even when the current density is 500 mA cm−2, which is prominently superior to IrO2(+)//Pt(−) coupled noble electrodes, and is among the very best bifunctional catalysts reported thus far. Detailed theoretical calculations reveal that the interfacial interaction between Fe2P and Co2N can further improve the H* binding energy at the iron sites.

Selective electron transport and extraction are essential to the operation of photovoltaic devices. Electron transport layer (ETL) is therefore critical to organic photovoltaics (OPV). Herein, an ETL configuration is presented comprising a solution‐processed n‐n organic heterojunction to enhance electron transport and hole blocking, and boost power conversion efficiency (PCE) in OPV. Specifically, the n‐n heterojunction is constructed by stacking a narrow‐band n‐type conjugated polymer layer (PNDIT‐F3N) and a wide‐band n‐type conjugated molecule layer (Phen‐NaDPO). Based on the ultraviolet photoelectron spectroscopy measurement and numerical simulation of current density‐voltage characteristics, the formation of the built‐in potential is investigated. In three OPVs with different active layers, substantial improvements are observed in performance following the introduction of this ETL configuration. The performance enhancement arises from the combination of selective carrier transport properties and reduced recombination. Another contributing factor is the good film‐forming quality of the new ETL configuration, where the surface energies of the related materials are well‐matched. The n‐n organic heterojunction represents a viable and promising ETL construction strategy for efficient OPV devices.
Degradation Pathways of Cobalt‐Free LiNiO2 Cathode in Lithium Batteries

Published: December 2022

Electrode‐electrolyte reactivity (EER) and particle cracking (PC) are considered two main causes of capacity fade in high‐nickel layered oxide cathodes in lithium‐based batteries. However, whether EER or PC is more critical remains debatable. Herein, the fundamental correlation between EER and PC is systematically investigated with LiNiO2 (LNO), the ultimate cobalt‐free lithium layered oxide cathode. Specifically, EER is found more critical than secondary particle cracking (SPC) in determining the cycling stability of LNO; EER leads to primary particle cracking, but mitigates SPC due to the inhibition of H2‐H3 phase transformation. Two surface degradation pathways are identified for cycled LNO under low and high EERs. A common blocking surface reconstruction layer (SRL) containing electrochemically‐inactive Ni3O4 spinel and NiO rock‐salt phases is formed on LNO in an electrolyte with a high EER; in contrast, an electrochemically‐active SRL featuring regions of electron‐ and lithium‐ion‐conductive LiNi2O4 spinel phase is formed on LNO in an electrolyte with a low EER. These findings unveil the intrinsic degradation pathways of LNO cathode and are foreseen to provide new insights into the development of lithium‐based batteries with a minimized EER and a maximized service life.

Hydrogel materials endow the flat optics platform with active tuning capability, owing to their remarkable humidity‐responsive swelling behavior. Despite recent advances in hydrogel‐based devices for spectral tuning, their complex patterning processing and limited functionality obstruct them from practical applications. Herein, a single‐step direct‐printing technique is originally demonstrated with an active hydrogel material platform for realizing unprecedented multi‐field full‐color display dynamics. Through exploring the dose‐induced shrinkage on polyvinyl alcohol, the stepwise hydrogel nanocavities sandwiched by ultrathin metallic films can be directly printed by grayscale e‐beam lithography. Due to the tunable structural coloration from hydrogel nanocavity scaling, multi‐functionalities are successfully created for optical concealment, dynamic coloring, and dynamic full‐color holography. By encoding the cavity‐dependent transmission phase into the direct‐printed hydrogel platform, it originally enables the projected full‐color holographic dynamics in real‐time by simply exhalation, beyond the static holographic display or monochromatic holographic switching. The proposed active displays can rapidly respond to the surrounding humidity change at a millisecond‐level (< 150 ms). Such a direct‐printing strategy for hydrogel nanocavity represents a critical advance toward the unprecedented dynamic full‐color display, and suggests promising applications in optical security, gas sensing, multispectral imaging, full‐color holography, and next‐generation display techniques.

Polyelemental material systems, specifically high‐entropy alloys, promise unprecedented properties. Due to almost unlimited combinatorial possibilities, their exploration and exploitation is hard. This challenge is addressed by co‐sputtering combined with shadow masking to produce a multitude of microscale combinatorial libraries in one deposition process. These thin‐film composition spreads on the microscale cover unprecedented compositional ranges of high‐entropy alloy systems and enable high‐throughput characterization of thousands of compositions for electrocatalytic energy conversion reactions using nanoscale scanning electrochemical cell microscopy. The exemplary exploration of the composition space of two high‐entropy alloy systems provides electrocatalytic activity maps for hydrogen evolution and oxygen evolution as well as oxygen reduction reactions. Activity optima in the system Ru–Rh–Pd–Ir–Pt are identified, and active noble‐metal lean compositions in the system Co–Ni–Mo–Pd–Pt are discovered. This illustrates that the proposed microlibraries are a holistic discovery platform to master the multidimensionality challenge of polyelemental systems.
