Richard E. Rubin and Rachel G. Rubin. Foundations of Library and Information Science. 5th ed. Chicago, IL: ALA Neal-Schuman, 2020. 656p. Paper.
Authors: Rabina Debbie
Published: January 2021

One of the tenets of a book review is a discussion of how well the book meets the needs of its intended audience, and, as far as target audience goes, this book was written for me. I teach a foundations course in a school of information and it is the likes of me that need to adopt this as our textbook as the final step in the production-consumption cycle. And so, it is in light of my needs that I set out to examine Richard E. Rubin and Rachel G. Rubin’s Foundations of Library and Information Science. The two questions I asked myself throughout were: Do I agree with the authors on what the foundations of the field are, and does their treatment of topics satisfy my teaching needs?
Considering Registered Reports at C&RL
Authors: Riegelman Amy
Published: January 2021

In January 2020, I presented at the Librarians Building Momentum for Reproducibility virtual conference. The theme of the presentation was preregistration and registered reports and their role in reproducibility of research results. The presentation was twofold in that it provided background information on these themes and then advocated for the adoption of a registered reports submission track in Library and Information Science journals. I asked attendees to notify me if they wanted to learn more and to join me in contacting LIS journals to advocate for this model. The first journal that we targeted was College & Research Libraries. We drafted a letter that was sent to editor Wendi Arant Kaspar who discussed the topic with the editorial board and ultimately asked me to write a guest editorial for C&RL.

Published: January 2021

De setembro a dezembro de 2017, quatro alunos da Universidade de Michigan treinados pelo Prison Creative Arts Project facilitaram um workshop de redação criativa na G. Ronald Cotton Correctional Facility em Jackson, Michigan, EUA. Doze homens encarcerados juntaram-se aos quatro alunos facilitadores para reuniões semanais de workshops que culminaram em uma apresentação de escrita criativa original. Este artigo descreve a estrutura do workshop e o treinamento fornecido pelo Prison Creative Arts Project, apresenta os indivíduos que participam deste workshop de redação criativa do outono de 2017 e descreve como seus processos criativos evoluíram para incluir discurso político e crítica. O artigo demonstra como a escrita criativa e o teatro fornecem à população encarcerada a oportunidade única de expressar plenamente as opiniões e atitudes políticas dentro dos muros da prisão e destaca paralelos entre os eventos atuais e a política de 2017 e os de 2020. Para completar este artigo, os alunos facilitadores escreveram uma carta descrevendo o projeto e pedindo interesse em coautoria e a enviaram aos participantes encarcerados. Os alunos facilitadores compilaram um questionário e o enviaram aos participantes encarcerados que estavam interessados ​​em ser coautores do artigo. Os coautores ainda residentes na prisão continuaram a se corresponder com aqueles que viviam fora da prisão via correio, produzindo seções do artigo e fornecendo redação original do workshop de 2017.
Zintkala Woihanbla (Sonhos de Pássaros): deriva e outras performances decoloniais para sobreviver a e abolir a prisão
Authors: Blu Wakpa Tria , Blue Bird George
Published: January 2021

Pesquisas muitas vezes negligenciaram como os nativos americanos, que estão desproporcionalmente presos, desenvolveram táticas para lidar com a prisão a longo prazo. Com base nas correspondências e conversas entre os autores, este ensaio apresenta performances decoloniais praticadas por George Blue Bird, em condições de violência carcerária, para sobreviver a e abolir a prisão. Estas táticas de enfrentamento são: 1. alimentar conexões com mais-que-humanos; 2. deriva, termo adotado por Blue Bird para imaginar, viajar e habitar outros reinos; e 3. ativar a liberdade e o futuro. Em última análise, concentramo-nos no que estas táticas e epistemologias Lakota oferecem ao movimento de abolição da prisão.

Authors: Silva Eliana Doraci da , Moraes Dayane Vicente de
Published: January 2021

Este artigo objetiva identificar projetos artísticos nos presídios masculinos de regime fechado no município de Campo Grande, estado de Mato Grosso do Sul, e compreender o uso desses projetos como dispositivo disciplinar da escola no ambiente prisional. Por meio dos referenciais foucaultianos busca-se tratar de problemáticas e tensões que emergem da disciplina ao corpo desses sujeitos. Verifica-se que o artesanato surge consideravelmente nas atividades e propostas de reinserção do sujeito para além dos muros da prisão, sendo utilizado pela instituição como ferramenta para ocupação do tempo do indivíduo, sem valorizá-lo como artista capaz de despertar novos olhares.
Para se pensar uma representatividade negra: reflexões sobre o corpo (não) negro nas artes cênicas
Authors: Dess Conrado
Published: January 2021

O autor propõe uma reflexão acerca das transformações sociais que levaram ao surgimento de um movimento que luta por representatividade negra nas artes cênicas nos últimos anos. A partir de uma observação de alguns dos modos como o corpo negro é representado em cena, em particular no espetáculo Entrevista com Stela do Patrocínio, pretende-se realizar uma reflexão sobre as implicâncias políticas e sociais causadas pela presença e pela ausência do corpo negro na cena.
Notas sobre a peça Acima de tudo: sociologia e filosofia como bases para a criação teatral
Authors: Valença Ernesto Gomes
Published: January 2021

O artigo descreve a metodologia utilizada para a criação da peça Acima de tudo – Teatro antifascista, enfatizando o modo como a dramaturgia e a encenação articularam as bases teóricas estudadas. O neofascismo foi abordado a partir de fontes filosóficas e sociológicas que permitiram estabelecer paralelos entre o período da Alemanha nazista e o Brasil atual, sendo o mais evidente a mobilização, para ideias totalitárias, do sentimento da solidão em meio à multidão. O celular foi tomado como símbolo dessa solidão massificada hiper conectada que gerou o fascismo no Brasil e empregado na encenação tanto como objeto de cena quanto como inspiração para todo o espetáculo.

Grotowski: O decoro profissional como imperativo metodológico
Authors: Pereira Filipe
Published: January 2021

Neste breve artigo defende-se que a dimensão ética, que é fundamental na metodologia proposta por Grotowski, resulta do extremar das mais simples regras de decoro profissional que são ensinadas nas escolas de teatro e postas em práticas pela maioria das companhias teatrais. Este aspecto é de extrema relevância, nas artes performativas como na sua pedagogia, quando considerada a dialéctica entre o “trabalho sobre si mesmo” e a alteridade. Aborda-se sucintamente o percurso artístico de Grotowski para defender uma dimensão ontológica da sua noção de Arte e demonstrar a coerência e linearidade do mesmo. Também concisamente, indicam-se as suas principais referências éticas e profissionais e como foram aplicadas na prática, realçando a importância conferida ao Outro. Termina-se argumentando em favor da ética como imperativo profissional e artístico no contexto grotowskiano, alicerçando-a no decoro profissional e na prática artística.
Educação e Teatro na Cadeia: Práticas pedagógicas realizadas no Sistema Penitenciário da Papuda/DF
Authors: Rodrigues Janilce
Published: January 2021

Este trabalho relata algumas práticas pedagógicas realizadas nas oficinas de teatro com internos do Sistema Penitenciário da Papuda, no Distrito Federal. Dialoga com o livro “Teatro em Cadeado - uma experiência em cela de aula”, publicado em 2019, como resultado do trabalho desenvolvido entre os anos de 2005 e 2013 nos presídios masculino e feminino. Ao propor possibilidades de liberdade num espaço opressor, a prática do teatro exerceu muitas funções positivas, não somente a expressão artística, mas a desconstrução da identidade marginalizada e oprimida dos presos. O exercício dessa linguagem artística surpreendeu o aluno/preso ao descobrir-se capaz de transformar sua realidade pessimista em um novo olhar para si, protagonizando um futuro libertador e transformador. O teatro, por fim, agiu como elemento humanizador e ressocializador para aqueles que puderam experimentá-lo dentro do sistema penitenciário.

Corpo - paisagem:
Authors: Lacerda Laís Miguel , Ribeiro Regilene Aparecida Sarzi
Published: January 2021

Trata-se de um estudo sobre identidade e nomadismo na arte contemporânea latino-americana a partir dos registros de performance. Exílio, territórios, deslocamentos e corpo são palavras chave para compreensão da obra Silueta Series (1974), composta por 200 fotografias realizadas em um período de aproximadamente sete anos, pela artista cubana Ana Mendieta (1948-1985). O artigo busca refletir os múltiplos conceitos intrínsecos na obra dessa artista pioneira que traz o corpo feminino como elemento central integrado a paisagem e ao nomadismo, além de questões de gênero, política, identidade e nomadismo que são subjetivamente estabelecidas de maneira atemporal.
poética de corpos múltiplos e heteróclitos de Oriana Duarte.
Authors: Salvi Carolina
Published: January 2021

O trabalho artístico de Oriana Duarte navega na fluidez e desterritorialização do corpo. Metamorfoseia a pedra sólida em sopa líquida, transformada em alimento pela fisiologia do corpo, acopla-se ao remo, transforma-se em barco, em ponte, altera a estrutura muscular e se imerge em edifícios e cidades. O corpo, para a artista, não possui um significado nem um organismo originário, mas se faz em campo de experimentações e possibilidades. Com uma prática quase inteiramente voltada para o próprio corpo, a artista realiza uma escrita de si que assume a função de compor-se, em si mesma e além-de-si, em uma existência ciborgue e híbrida, escapando às normas de corpo feminino passivo antes canonizados na arte. Assim, Oriana Duarte vem, através da performance, traçando uma vida artista em constante diálogo com elementos da natureza e tecnologias humanas, tendo o corpo no epicentro dessa relação.
Escola Comunitária – Integração Escola e Comunidade: mobilizar é transformar?
Authors: Rubio Fernanda Eiras
Published: January 2021

Este artigo em arte educação tem o objetivo de relatar os percursos criados, estruturados, tateados e realizados pelo projeto Escola Comunitária – Integração Escola e Comunidade, no bairro da Aclimação, na cidade de São Paulo no ano de 2019, através das noções de cooperação (FREINET), dos territórios livres (RAGO) e da experiência (LARROSA). Como ferramenta de interação com a comunidade durante as pesquisa-ações utilizamos o conceito de estética relacional (BOURRIAUD). A partir de 2020 com a pandemia de coronavírus ocorreram mudanças no plano de ações do projeto devido ao isolamento social. Dada essa realidade, iniciamos um processo de adaptações experimentando novamente outras estruturas de organização, comunicação, solidariedade e encaminhamentos nas plataformas virtuais junto com a comunidade. Utilizamos a ideia de comunidade de aprendizagem (TORRES) onde por meio das nossas próprias forças buscamos suprir nossas carências. Refletimos sobre nossas tentativas de criação e mobilização com diversos grupos, vizinhos e funcionários públicos no nosso território e se podemos transformar nossa realidade local pela práxis, com a participação de variados atores trabalhando em colaboração e parceria com as escolas públicas da região.
Liturgical Paraphernalia and Decor Elements of the Parish Churches of the Diocese of Samogitia in the First Half of the Seventeenth Century
Authors: Jovaiša Liudas
Published: January 2021

The article provides an overview (both in terms of types and amount) of liturgical paraphernalia (vessels, vestments, and processional items), musical instruments (organs and bells), and other items of church interior (pews, candlesticks, chandeliers, commemorative plaques, sacristy furniture, boxes for holy oils, offering boxes, wallpapers, sepulchral banners, and stoups) extant in the parish churches of the diocese of Samogitia in the first half of the seventeenth century. The overview is based on the information contained in visitation acts and inventories due to the fact that only a few material pieces of sacral art dating back to the mentioned period have survived until now. Historical sources enabled a description of the whole repertoire of liturgical paraphernalia of the parish churches of the above-mentioned diocese (in the first half of the seventeenth century) for the first time. The overview reveals some transformations of the older practice, occasionally witnessed in local sources of the sixteenth century. More significantly, it enables future research based on a comparison of the described material with the information contained in wider chronological and geographical (first of all, including the diocese of Vilnius) contexts.
Traces of the History of One Painting of the Sacred Heart of Jesus
Authors: Stankevičienė Regimanta
Published: January 2021

Kazimierz and Ewa (of Uwoyni) Burba, the wojskis (officials attending to the needs of soldiers’ families during wars) of Šiauliai and collators of the Church of St Peter and St Paul in Apytalaukis, donated the painting “The Sacred Heart of Jesus” to the high altar of the church in 1817. From 1755, when a fraternity of the Sacred Heart of Jesus was established, this altar had been decorated with an earlier painting of the same name. The painting donated by the Burba decorated the first tier of a new high altar erected after 1817 and the existing high altar that was built before 1920s (?). It is believed that due to its poor condition, the old painting was replaced with a copy during repairs in 1964, and it is this copy that is on the altar to date. In 2019, the painting was restored as it had lost many fragments of the paint layer, especially at the bottom. The prototype of this painting is the painting “The Sacred Heart of Jesus and the Eucharist” by Pietro Tedeschi (the Church of the Blessed Virgin Mary of Mount Carmel, Imola, 1780). It is believed that the painter used an engraving of this image, presumably by Lorenzo Capponi. The painting in the church in Apytalaukis is narrower and therefore the baroque composition created by Pietro Tedeschi is somewhat reduced and adjusted. In addition, the drawing, rhythm, and colours of the painting of 1817 are characteristic of the features of the classicist style and paintings of the Vilnius School of Art. Due to the analogies of stylistics and the wellknown fact of Kazimierz Burba’s acquaintance with the painter Jan Rustem, the painting is hypothetically attributed to this artist. The face of Jesus in the painting in Apytalaukis can be compared to Burba’s portrait by Jan Rustem (unfortunately, only a copy has survived). We propose the title “The Eucharistic Sacred Heart of Jesus” as it defines the iconography of the painting more precisely.

Dois ensaios sobre utopia
Authors: Almino João
Published: January 2021

O tema da utopia continua atual e merece reflexão renovada. Este livro propõe interpretações originais e oportunas do clássico de Thomas More. No primeiro ensaio, a análise da estrutura narrativa da obra como peça literária, encenada por vários personagens, entre os quais quatro narradores, permite concluir que, por meio da dialética dos diálogos e do confronto entre os personagens, Utopia, em vez de elaborar uma demonstração linear, não sugere receitas prontas para serem aplicadas. Deixa espaço para o dissenso. Ser ficção é uma vantagem, que atenua a “distopia” presente no livro de More – “distopia” manifesta na organização totalitária de uma sociedade que se quer transparente para si mesma e onde não há divisão entre o público e o privado. Ela se evidencia também, como defende o segundo ensaio, na ordem internacional unidimensional, unilateral, em que as regras são impostas por um só ordenador do mundo, autossuficiente e todo-poderoso intérprete do bem, que se crê detentor dos valores da civilização.
Expression of vitamin D 1α-hydroxylase in human gingival fibroblasts in vivo
Authors: Liu Kaining , Han Bing , Hou Jianxia , Zhang Jianyun , Su Jing , Meng Huanxin
Published: January 2021

Background

Vitamin D 1α-hydroxylase CYP27B1 is the key factor in the vitamin D pathway. Previously, we analyzed the expression of CYP27B1 in human gingival fibroblasts in vitro. In the present study, we analyzed the gingival expression of CYP27B1 in vivo.

Methods

Forty-two patients with periodontitis Stage IV Grade C and 33 controls were recruited. All patients with periodontitis had unsalvageable teeth and part of the wall of the periodontal pocket was resected and obtained after tooth extraction. All controls needed crown-lengthening surgery, and samples of gingiva resected during surgery were also harvested. All the individuals’ gingivae were used for immunohistochemistry and immunofluorescence. In addition, gingivae from seventeen subjects of the diseased group and twelve subjects of the control group were analyzed by real-time PCR.

Results

Expression of CYP27B1 was detected both in gingival epithelia and in gingival connective tissues, and the expression in connective tissues colocalized with vimentin, indicating that CYP27B1 protein is expressed in gingival fibroblasts. The expression of CYP27B1 mRNA in gingival connective tissues and the CYP27B1 staining scores in gingival fibroblasts in the diseased group were significantly higher than those in the control group.

Conclusions

Expression of CYP27B1 in human gingival tissues was detected, not only in the fibroblasts of gingival connective tissues, but also in the gingival epithelial cells, and might be positively correlated with periodontal inflammation.

Authors: Sunandini G. P. , Paul K. Solmon Raju , Irugu Shakuntala Devi
Published: January 2021

The study has been taken up with the objective of investigating the trends, pattern of growth and the extent of instability in area, production and productivity of rice crop in Andhra Pradesh state over a period of five and half decades from 1959-60 to 2013-14. Compound Growth Rate and Coefficient of Variation were used to calculate the annual growth rate and instability. The area, production and productivity of rice in this period has increased by 25, 201 and 138 per cent respectively. In this period, the districts were categorised and grouped under different groups based on average productivity of rice. During the study period many of the districts moved from very low productivity to high productivity group. During 1960s, 17 districts are under very low productivity group (<1500 kg/ha) and in 2010s 13 districts are under high productivity group (>3000 kg/ha). During the period 2014-19 in the divided Andhra Pradesh contribution of different productivity groups to the states paddy production was calculated and concluded that 3 districts under high productivity group (>6000kg/ha) contributed 52 per cent of the production. During 2010s annual growth rates for area, production and productivity are 4.08, 4.02 and 1.21 respectively. In all the periods in the past five and half decades, production and productivity growth rates are higher than growth rate in area except in 2010s. Instability was higher in production and area than in productivity.  The annual growth rate and the instability of production and area are higher in 2010s. Suitable crop planning is to be initiated, adoption of sustainable management practices are to be intensified to maintain the growth rate and reduce the instability in area and production.
Bibliometric and Scientometric Analysis of Scopus-Indexed Literature on Hemp (Cannabis sativa) Breeding
Authors: Ndlovu Noel , Banda Leah , Muitire Clemence , Munyengwa Norman , Mayaya Tatenda
Published: January 2021

The elevated research interest and increased cultivation of Hemp (Cannabis sativa) across the globe is significantly driven by its multidirectional industrial uses and medicinal properties. Scientific research publications focusing on hemp breeding plays a pivotal role in bridging the knowledge gap and opening new avenues for upscaling the efficiency of crop improvement initiatives. The identification of prevailing research trends and associations is critical in defining and mapping the trajectories of success in Hemp breeding. The advent of bibliometrics and scientometrics is currently providing a stead platform which fosters effective identification of current research patterns and examination of the applied methodologies, focus areas, and operational constraints. In the context of Hemp research, content assessments provide breeding initiatives with background data needed for exploring various traits of interest and for validating investments and related policies. The main thrust of this study is to perform a bibliometric and scientometric analysis of Scopus-indexed papers covering the field of ‘Hemp Breeding’, between calendar years 1908 and 2020. Data was analyzed using VOSviewer (Version 1.6.16) and Microsoft Excel (2019). The study found 152 papers composed of original articles (105, 69.08%), book chapters (23, 15.13%), conference papers (10, 6.58%), reviews (9, 5.92%), conference reviews (3, 1.97%) and books (2, 1.32%). A significant increment in research publications was observed after 1950. The assessment also indicated that most of the archived research was conducted or reported in the USA (13.82%), Italy (12.5%) and the Netherlands (11.18%). Furthermore, the highest number of papers over the studied period and topic were published by authors affiliated to Wageningen University & Research (16, 10.53%). Index keywords such as Cannabis sativa, hemp, genetic expression, genetic marker, and genetic diversity were covered extensively in the sampled journal editions. A comparative assessment of the results indicated that there is need to scale-up research initiatives targeting hemp trait improvements to cater for the projected high demand and climate change. This can be achieved through strengthening synergistic partnerships and knowledge exchanges across the hemp breeding value chain. This research will assist plant breeders in defining research requirements, determining evidence-based scientific gaps, and recognizing outstanding research institutions for potential intellectual sharing and cooperation.
Vernal Keratoconjunctivitis with Atypical Localization of Shield Ulcer
Authors: Hovakimyan Anna , Kambulyan Lusine , Davtyan Araks , Kirakosyan Artak , Tsarukyan Emma
Published: January 2021

Aims: To present an atypical case of vernal keratoconjunctivitis associated with unusual inferior location of shield ulcer.

Presentation of Case: We are presenting an unusual case of vernal disease in a 7-year-old male associated with 2 corneal ulcers in the same eye, one of which was located inferiorly. The patient was prescribed topical steroids, antihistamine and lubricating eye drops. Three weeks later the symptoms got resolved and ulcers were healed, leaving mild subepithelial fibrosis. The patient was advised to continue antihistamine eye drops for the whole year with prophylactic dosage regimen.

Discussion: Vernal keratoconjunctivitis is a bilateral, seasonally recurring inflammation of conjunctiva and cornea. It affects mostly children with male preponderance. In several cases vernal disease can be complicated with development of a shield ulcer, which usually has superior location under upper eyelid. Despite the fact that literature review has revealed two atypical cases with inferior localization reported in India, it is a very rare finding. Our case also was unusual with two shield ulcers, one of which was located inferiorly.

Conclusion: This case demonstrates a very rare presentation of an atypical inferiorly located shield ulcer. Literature review revealed only two similar cases in India. Our case demonstrates the usage of topical steroids to be successful and advisable in the treatment of shield ulcer, as it controls the inflammation. Topical antihistamine medications should be added and given for a long period for preventing possible recurrences.

Paired serum and cerebrospinal fluid (CSF) samples were obtained from 101 patients with SLE when they presented active neuropsychiatric manifestations (69 patients with diffuse psychiatric/neuropsychological syndromes [diffuse NPSLE] and 32 patients with neurologic syndromes or peripheral nervous system involvement [focal NPSLE]) and from 22 control patients without SLE with noninflammatory neurological diseases. The levels of albumin and IL‐6 in CSF and sera were measured by enzyme‐linked immunosorbent assay.

Results

Serum IL‐6 and CSF IL‐6 were elevated in NPSLE compared with non‐SLE controls. Among NPSLE, serum IL‐6 and CSF IL‐6 were significantly elevated in acute confusional state (ACS) compared with non‐ACS diffuse NPSLE (anxiety disorder, cognitive dysfunction, mood disorder, and psychosis) or focal NPSLE. Q albumin (CSF/serum albumin quotient) was also significantly higher in ACS than in the other two groups of NPSLE. Of note, serum IL‐6 (r = 0.2801, p = 0.0207), but not CSF IL‐6 (r = 0.1602, p = 0.1918), was significantly correlated with Q albumin in patients with diffuse NPSLE, including ACS and non‐ACS.

Conclusion

These results indicate that serum IL‐6 as well as CSF IL‐6 is involved in the pathogenesis of NPSLE. Moreover, it is suggested that serum IL‐6 might play a most important role in blood‐brain barrier breakdown in NPSLE.
Pluralism and the Urban Landscape: Towards a Strategic Eclecticism
Authors: Somers Dirk
Published: January 2021

Whilst Multiform has achieved a certain acceptance as a way of combating the so‐called New London Vernacular's contextual architecture, there are still many other aspects of urbanism it does not necessarily address, particularly within the public realm. The cityscape is often left out of the debate where buildings risk becoming simply self‐referential objects. Dirk Somers, manager and founder of Antwerp's Bovenbouw architectuur, argues for a reconsideration and posits successful precedents that balance convention with surprise.

Demineralized bone matrix (DBM), a potential alternative to autologous bone grafts, has been increasingly used for clinical bone repair; however, its application in larger defects has not been successful partly due to the rapid dispersion of DBM particles and relatively lower osteoinductivity. Here, a novel strategy is created to complement the osteoinductivity of DBM by incorporating DBM in a biopolymer hydrogel combined with the abrogation of BMP antagonism. Combined treatment of DBM+noggin‐suppression displays increased osteogenic potency of human bone marrow mesenchymal stem cells (hBMSCs) in vitro. An injectable chitosan (MeGC)‐based hydrogel with heparinization (Hep‐MeGC) is further developed to localize and stabilize DBM. Noggin‐suppression reveals a significant increase in osteogenesis of hBMSCs in the photopolymerizable Hep‐MeGC hydrogels with the encapsulation of DBM. Moreover, the combination of DBM+noggin‐suppression in the injectable Hep‐MeGC hydrogel displays robust bone healing in mouse critical‐sized calvarial defects in vivo. The mechanistic analysis demonstrates that noggin‐suppression increases DBM osteoinductivity by stimulating endogenous BMP/Smad signals. These results have shown promise in DBM's ability as a prominent bone grafting material while being coupled with gene editing mechanism and a localizing 3D scaffold. Together, this approach poses a significant increase in the efficiency of DBM‐mediated craniofacial bone repair and dental osteointegration.

It is becoming increasingly clear that mechanical stress in adhesive junctions plays a significant role in dictating the fate of cell–cell attachment under physiological conditions. Targeted disruption of cell–cell junctions leads to multiple pathological conditions, among them the life‐threatening autoimmune blistering disease pemphigus vulgaris (PV). The dissociation of cell–cell junctions by autoantibodies is the hallmark of PV, however, the detailed mechanisms that result in tissue destruction remain unclear. Thus far, research and therapy in PV have focused primarily on immune mechanisms upstream of autoantibody binding, while the biophysical aspects of the cell–cell dissociation process leading to acantholysis are less well studied. In work aimed at illuminating the cellular consequences of autoantibody attachment, it is reported that externally applied mechanical stress mitigates antibody‐induced monolayer fragmentation and inhibits p38 MAPK phosphorylation activated by anti‐Dsg3 antibody. Further, it is demonstrated that mechanical stress applied externally to cell monolayers enhances cell contractility via RhoA activation and promotes the strengthening of cortical actin, which ultimately mitigates antibody‐induced cell–cell dissociation. The study elevates understanding of the mechanism of acantholysis in PV and shifts the paradigm of PV disease development from a focus solely on immune pathways to highlight the key role of physical transformations at the target cell.
Electrowetting‐Assisted Generation of Ultrastable High Charge Densities in Composite Silicon Oxide–Fluoropolymer Electret Samples for Electric Nanogenerators
Authors: Mendel Niels , Wu Hao , Mugele Frieder
Published: January 2021

Electric nanogenerators that directly convert the energy of moving drops into electrical signals require hydrophobic substrates with a high density of static electric charge that is stable in “harsh environments” created by continued exposure to potentially saline water. The recently proposed charge‐trapping electric generators (CTEGs) that rely on stacked inorganic oxide–fluoropolymer (FP) composite electrets charged by homogeneous electrowetting‐assisted charge injection (h‐EWCI) seem to solve both problems, yet the reasons for this success have remained elusive. Here, systematic measurements at variable oxide and FP thickness, charging voltage, and charging time and thermal annealing up to 230 °C are reported, leading to a consistent model of the charging process. It is found to be controlled by an energy barrier at the water‐FP interface, followed by trapping at the FP‐oxide interface. Protection by the FP layer prevents charge densities up to −1.7 mC m−2 from degrading and the dielectric strength of SiO2 enables charge decay times up to 48 h at 230 °C, suggesting lifetimes against thermally activated discharging of thousands of years at room temperature. Combining high dielectric strength oxides and weaker FP top coatings with electrically controlled charging provides a new paradigm for developing ultrastable electrets for applications in energy harvesting and beyond.

Real‐time, high signal intensity, and prolonged detection is challenging because of the rarity of fluorophores with both high photostability and luminescence efficiency. In this work, new donor–acceptor (D–A) molecules for overcoming these limitations are reported. A hybridized local and an intramolecular charge‐transfer excited state is demonstrated to afford high photoluminescence efficiency of these D–A molecules in solution (≈100%). The twisted molecular structure and bulky alkyl chains effectively suppress π–π and dipole–dipole interactions, enabling high luminescence efficiency of 1 and 2 in the solid state (≈94% and 100%). Furthermore, two D–A aggregates exhibit high photostability as evidenced by 4% and 8% of the fluorescence decreasing after 6 h of continuous irradiation in air, which is in sharp contrast to ≈95% of fluorescence decreasing in a reference compound. Importantly, with these molecules, ultrasensitive detection of sulfur mustard (SM) with a record limit of 10 ppb and selective detection of SM in complex matrices are achieved.

Published: January 2021

The establishment of tumor microenvironment using biomimetic in vitro models that recapitulate key tumor hallmarks including the tumor supporting extracellular matrix (ECM) is in high demand for accelerating the discovery and preclinical validation of more effective anticancer therapeutics. To date, ECM‐mimetic hydrogels have been widely explored for 3D in vitro disease modeling owing to their bioactive properties that can be further adapted to the biochemical and biophysical properties of native tumors. Gathering on this momentum, herein the current landscape of intrinsically bioactive protein and peptide hydrogels that have been employed for 3D tumor modeling are discussed. Initially, the importance of recreating such microenvironment and the main considerations for generating ECM‐mimetic 3D hydrogel in vitro tumor models are showcased. A comprehensive discussion focusing protein, peptide, or hybrid ECM‐mimetic platforms employed for modeling cancer cells/stroma cross‐talk and for the preclinical evaluation of candidate anticancer therapies is also provided. Further development of tumor‐tunable, proteinaceous or peptide 3D microtesting platforms with microenvironment‐specific biophysical and biomolecular cues will contribute to better mimic the in vivo scenario, and improve the predictability of preclinical screening of generalized or personalized therapeutics.

Published: January 2021

Although metal–organic frameworks (MOFs) are being widely used to derive functional nanomaterials through pyrolysis, the actual mechanisms involved remain unclear. In the limited studies to date, elemental metallic species are found to be the initial products, which limits the variety of MOF‐derived nanomaterials. Here, the pyrolysis of a manganese triazolate MOF is examined carefully in terms of phase transformation, reaction pathways, and morphology evolution in different conditions. Surprisingly, the formation of metal is not detected when manganese triazolate is pyrolyzed in an oxygen‐free environment. Instead, a direct transformation into nanoparticles of manganese nitride, Mn2Nx embedded in N‐doped graphitic carbon took place. The electrically conductive Mn2Nx nanoparticles show much better air stability than bulk samples and exhibit promising electrocatalytic performance for the oxygen reduction reaction. The findings on pyrolysis mechanisms expand the potential of MOF as a precursor to derive more functional nanomaterials.

Achieving efficient passivating carrier‐selective contacts (PCSCs) plays a critical role in high‐performance photovoltaic devices. However, it is still challenging to achieve both an efficient carrier selectivity and high‐level passivation in a sole interlayer due to the thickness dependence of contact resistivity and passivation quality. Herein, a light‐promoted adsorption method is demonstrated to establish high‐density Lewis base polyethylenimine (PEI) monolayers as promising PCSCs. The promoted adsorption is attributed to the enhanced electrostatic interaction between PEI and semiconductor induced by the photo‐generated carriers. The derived angstrom‐scale PEI monolayer is demonstrated to simultaneously provide a low‐resistance electrical contact for electrons, a high‐level field‐effect passivation to semiconductor surface and an enhanced interfacial dipole formation at contact interface. By implementing this light‐promoted adsorbed PEI as a single‐layered PCSC for n‐type silicon solar cell, an efficiency of 19.5% with an open‐circuit voltage of 0.641 V and a high fill factor of 80.7% is achieved, which is one of the best results for devices with solution‐processed electron‐selective contacts. This work not only demonstrates a generic method to develop efficient PCSCs for solar cells but also provides a convenient strategy for the deposition of highly uniform, dense, and ultra‐thin coatings for diverse applications.
