Authors: Patria Gaffy
Published: November 2022

The large amount of final project document data from study programs at the Sekolah Tinggi Manajemen Informatika dan Komputer (STMIK) Abulyatama can make a major contribution to the difficulty of the process of grouping a student's final project theme. The clustering process that has been carried out manually so far has been very ineffective and inefficient, so a data mining application is needed to manage the data, especially for clustering the data. The goal to be achieved from writing this thesis is to implement the Support Vector Machine with K-Means and K-Medoids to optimize the final assignment clustering. the results of the Optimization Support Vector Machine (SVM) analysis using K-Means and K-Medoids for Grouping Student Final Project Themes can be concluded in a number of ways, namely; with the K-Means Clustering method it can be seen that there are 23 data mining, 10 networks, 26 artificial intelligence, and 21 websites, and website 11 items.

The purpose of the research is to present the purposive development of the cognitive component of the metalinguistic competency with the help of the metalinguistic strategies used in the process of mastering the foreign language (English) by students-linguists in institutions of higher education as a way to increase the psycholinguistic level of the metalinguistic competency. The research methodology. Different theoretical and practical methods and techniques have been used in the research: deductive and inductive methods, the analysis and synthesis of scientific literature sources devoted to the problems of psychology, linguistics, psycholinguistics, the generalization of scientific investigations, the systematization, the interpretation, the separation of the baselines, the characterization of the discussions selected taking into account their intentional and purposeful orientation, conclusions, the method of observation and introspection, the questioning (the developed questionnaire by the authors), conversation, testing, analysis of the quantitative and qualitative results. The scientific novelty lies in the fact that the focus of the authors’ attention is not just the development of the purposive metalinguistic competency as one of the components of professional communicative competency in particular, and the metacognitive competence in general, but also its cognitive component that provides readiness for mastering the metalinguistic competency as one of the main activities implemented in the process of teaching foreign languages and their learning. The Conclusions. The phenomenon of the cognitive component of the metalinguistic competency has not been well studied yet. The metalinguistic strategies suggested by the authors are based on students awareness of their language, thinking, and social skills and abilities. During and after the experiment, it has been determined that the purposive development of the cognitive component of the metalinguistic competency together with the practical use of meta-speech and metamethods allows expanding the amount of processed, reproducible, and productive information.

One-Dimensional Simultaneous Achiral and Chiral Analysis
Authors: Blue Laura E.
Published: November 2022

Most molecules with therapeutic value have at least one chiral center, requiring resolution of both achiral and chiral impurities. Separate achiral and chiral methods are the most used methodologies, but two-dimensional (2D) methods and columns in series have also been implemented. Having a mixed-mode column that can provide both achiral and chiral resolution in one-dimension (1D) would significantly improve impurity profile understanding and reduce testing workload.

Analysis of Serum from Acute Leukemia Patients Using Surface-Enhanced Raman Spectroscopy (SERS)
Authors: Han Hongwen , Gong Jingjing , Tian Yannan
Published: November 2022

In this paper, we show surface-enhanced Raman spectroscopy (SERS) of serum from acute leukemia and analyze the SERS through the multivariate statistical method of principal component analysis (PCA). First, the changes in the structure of proteins, lipids, carbohydrates, and other substances in the serum of patients with acute leukemia are analyzed from the molecular perspective. The results showed that the ordered structure of the protein main chain and the side chain conformation was weakened, the main chain structure was almost broken, and the protein became loose and disordered. In addition, the content of esters, amino acids, glycoproteins, and carbohydrate-related substances decreases, indicating a change in the environment. Finally, the PCA method was used to analyze the SERS signal of the serum of healthy people and patients with acute leukemia to accurately distinguish the two serum samples. The above conclusions can provide a favorable experimental basis for diagnosing leukemia and the study of the biochemical mechanism involved.

Published: November 2022

Historicamente, a Educação Infantil no âmbito nacional esteve atrelada a um ambiente escolar propício para as primeiras relações sociais dos alunos que integram uma instituição formal. Essa associação entre interação e ensino encontra-se enraizada no contexto escolar das instituições que contemplam essa etapa, visto que o surgimento das primeiras turmas infantis tinha como base o assistencialismo. Essa realidade pode ter contribuído para que, atualmente, grande parte da população ainda perceba a Educação Infantil como uma etapa apenas de socialização e cuidado com a criança. Tendo como ponto de referência a Alfabetização Científica para uma atuação do sujeito nos mais diversos ambientes, este artigo se constitui partindo do questionamento: os professores que atuam nas turmas finais da Educação Infantil vislumbram a possibilidade de implementar a Alfabetização Científica a partir do componente curricular de Ciências da Natureza? O presente estudo de abordagem qualitativa tem por objetivo identificar a concepção de professores atuantes na Educação Infantil em escolas municipais de uma cidade do Oeste do estado do Paraná quanto à possibilidade de implementar a Alfabetização Científica nas aulas de Ciências da Natureza. Os dados foram constituídos a partir do questionário disponibilizado pela ferramenta digital Google Forms.  Para a análise do “corpus” adotou-se a Análise Textual Discursiva. A pesquisa evidenciou a relevância da Alfabetização Científica como dispositivo para formação cidadã do estudante, bem como sua importância para as crianças da Educação Infantil como um artefato colaborativo de promoção de alunos mais participativos nas relações sociais.
Voluntary Simplicity and Materialism: Different Cognitive and Attitudinal Drivers and Different Effects on Self-Brand Connections
Authors: Pashkevich Vladimir
Published: November 2022

Although "simple" brands encouraging mindfulness and favoring minimalism are becoming popular at rapidly increasing rates, the relationship between consumer materialism or voluntary simplicity (VS) ideology and formation of consumer self/brand connections after exposure to the ads with materialistic or VS theme has not been studies and directly compared. The process underlying the formation of self/brand connections has not being empirically tested either. This paper addresses these gaps in the literature by using an experimental approach. The findings indicate that after exposure to the ad with VS (but not materialistic) appeal, voluntary simplifiers form strong bonds with the brand. On the other hand, materialistic consumers form strong self/brand connections when exposed to the ads with both materialistic and VS appeals. The findings show that both high materialists and simplifiers form brand connections when exposed to the ads with VS appeal, but for fundamentally different reasons. Materialism fosters self-brand connections by evoking thoughts about wisdom and good life, while voluntary simplicity fosters self-brand connections by evoking ad-related nostalgic thoughts and thoughts about equality. The results have important implications for brand managers trying to forge strong brand connections while targeting segments of consumers with different values.
The Liturgy of St John Chrysostom: a work of ecclesiastical or concert character?
Authors: Harkavyy Oleh
Published: November 2022

When a composer intends to write a setting of the Liturgy of St John Chrysostom (“Liturgy”, for short), he or she needs to be sure what the character of the work to be composed would be: ecclesiastical in character, to be performed in church during a service, or of a concert character to be performed in a concert hall?
What are the differences between the works of ecclesiastical character and works of concert character? To answer the question, we need to compare a performance of a musical work in church during a service and at a concert hall during a concert, i.e., using the method of oppositions. We need to consider the opposition “service/church – concert/concert hall” in the context of a musical performance.

U

Using primary data collected from in-depth interviews with 11 practical experts who have been working in the commodity industry for 7 years on average and using the Bollinger Bands tool for 3 years at least, the article shows that Bollinger Bands' signs on price forecasts or making decisions to buy or sell in the future trading of agricultural products in Vietnam are highly appreciated because of their accuracy. In addition, by using the Analytical Hierarchy Process (AHP) approach, the research indicates that there is no big difference in the effectiveness of Bollinger Bands’ application in future transactions for coffee, corn, wheat, soybean and soybean oil. However, applying Bollinger Bands in coffee futures’ trading is the most effective. In addition, the study also emphasizes the combination of Bollinger Bands with other technical analysis tools such as RSI, MACD, Fibonacci, Ichimoku, and CCI, to improve transaction efficiency.

غزلیات مدحی شاعران دورۀ تلفیق با تأکید بر کاربرد ویژۀ ضمیر «شما» در جای‌گاه ردیف
Authors:   Associate Professor of Persian Language and Literature, Allameh Tabatabaʼi University, Tehran, Iran, Tayefi Dr.Shirzad
Published: November 2022

سنایی اولین کسی است که واژۀ «شما» را در جای‌گاه ردیف غزل آورده است. این غزل مضامین مدحی دارد و به نظر می‌رسد که قرار گرفتن واژۀ «شما» در جای‌گاه ردیف آغازگر تحولی در جریان غزل فارسی باشد. بدون شناخت جای‌گاه واژۀ «شما» در جریان‌شناسی غزل فارسی، نکته‌یی نغز از چشم پژوهش‌گران پوشیده خواهد ماند؛ زیرا از مهم‌ترین نشانه یا مؤلفۀ لفظی روشنی‌بخشی برای تحول مضمون در غزل فارسی غفلت ورزیده‌ایم. با جریان‌شناسی غزل فارسی و پی‌گیری واژۀ «شما» در جای‌گاه ردیف پی می‌بریم که در ادب فارسی از چه زمانی غزل‌های مدحی رواج فراوانی پیدا کرد و واژۀ مزبور به عنوان نشانه‌یی روشنی‌بخش برای جست‌وجوی این مسیر شناخته خواهد شد. در این پژوهش به این پرسش پاسخ داده‌ایم که به‌لحاظ مضمونی، در جریان‌شناسی غزل فارسی واژۀ «شما» در جای‌گاه ردیف چه نقشی را ایفا کرده است؟ فرض ما بر این است که ذکر «شما» در جای‌گاه ردیف با ظهور مدح ممدوح/ معشوق در غزل مقارن و سبب شکل‌گیری جریانی برای ورود مضمون مدح به غزل و استفادۀ متداول از این ردیف برای غزل مدحی شاعرانِ پس از سنایی شده است. این پژوهش به روش توصیفی- تحلیلی انجام‌یافته است. یافته‌های پژوهش نشان می‌دهند؛ اگر چه مدحی‌بودن غزل با ردیف «شما» از سنایی چندان مسلم به نظر نمی‌رسد؛ اما با‌توجه به این‌که سنایی نیز در غزلیات خود از مضامین مدحی بهره برده است دور نیست که تصور کنیم شاعران قرن هشتم استفاده از ظرفیت این ضمیر را از سنایی به وام گرفته باشند.

Sleep Disordered Breathing in Children
Authors: Yang Yeonmi
Published: November 2022

Sleep disordered breathing (SDB) is a disease characterized by repeated hypopnea and apnea during sleep due to complete or partial obstruction of upper airway. The prevalence of pediatric SDB is approximately 12 - 15%, and the most common age group is preschool children aged 3 - 5 years. Children show more varied presentations, from snoring and frequent arousals to enuresis and hyperactivity. The main cause of pediatric SDB is obstruction of the upper airway related to enlarged tonsils and adenoids. If SDB is left untreated, it can cause complications such as learning difficulties, cognitive impairment, behavioral problems, cardiovascular disease, metabolic syndrome, and poor growth. Pediatric dentists are in a special position to identify children at risk for SDB. Pediatric dentists recognize clinical features related to SDB, and they should screen for SDB by using the pediatric sleep questionnaire (PSQ), lateral cephalometry radiograph, and portable sleep monitoring test and refer to sleep specialists. As a therapeutic approach, maxillary arch expansion treatment, mandible advancement device, and lingual frenectomy can be performed. Pediatric dentists should recognize that prolonged mouth breathing, lower tongue posture, and ankyloglossia can cause abnormal facial skeletal growth patterns and sleep problems. Pediatric dentists should be able to prevent these problems through early intervention.

Published: November 2022

The purpose of this study was to evaluate the effect of interceptive primary canine extraction in palatally and buccally displaced maxillary permanent canines, and to analyze the clinical and radiographic factors affecting the treatment outcome. 97 maxillary permanent canines from 86 patients whose maxillary permanent canine were in the mesio-occlusal directions and overlapped with the roots of the adjacent teeth were analyzed. In 64 of 97 (66.0%) maxillary permanent canines, the displaced crown was completely deviated from the adjacent lateral incisor root only by extraction of the primary canine. Not only the characteristics of maxillary permanent canines such as bucco-palatal displacement direction, horizontal and vertical position of the crown tip, and presence of apical closure, but also periapical rarefaction on the primary canine and peg-shaped adjacent lateral incisor significantly affected the treatment outcome.
Investigation of Stress-Inducing Factors and Occupational Stress Levels in General and Pediatric Dentists
Authors: Kim Seunghyun , Lee Jaesik
Published: November 2022

The purpose of this study was to compare factors causing stress in pediatric and general dentists when treating pediatric patients and to evaluate their overall occupational stress level. A total of 191 dentists participated in the online survey, consisting of 66 pediatric dentists and 125 general dentists. The questionnaire was conducted using Google Form. Both groups were stressed due to poor cooperation of patient and caregiver, uncertain prognosis of treatment, and low cost of pediatric dental treatment. The pediatric dentists felt relatively high stress due to poor cooperation from caregivers and an uncertain prognosis of treatment (p < 0.05). Overall occupational stress was high in both groups in the order of patient, time, job environment, and income-related stress, and the degrees of pediatric dentists were lower than general dentists. Among the 3 sub-factors of occupational burnout, more than 98% of both groups showed burnout in “depersonalization”, and more than 69% of both groups showed burnout in “emotional exhaustion”. Both groups showed a low burnout rate in “reduced sense of accomplishment” and pediatric dentists showed a higher sense of accomplishment than general dentists (p < 0.05). This study showed that both groups were under high occupational stress due to various factors, and efforts were required to relieve stress.

Published: November 2022

The purpose of this study is to evaluate the antibacterial effects of two liquid fluoride materials on Streptococcus mutans (S. mutans). Riva star aqua™ (SDI, Bayswater, Australia), which consists of silver fluoride (AgF, step 1) and potassium iodide (KI, step 2), and Fluor protector® (FP; Ivoclar Vivadent, Liechtenstein) were used for experimental groups. Experimental groups were divided into 4 groups : AgF, KI, AgF + KI and FP. For the positive control (PC) group, ampicillin was used, and the negative control group (NC) did not receive any additional treatment. Each group was divided into 30 and 50 µL groups by volume of liquid and applied to flat-coated S. mutans. The diameter of the zone of inhibition was measured. The PC and AgF groups showed larger diameters than other materials (p < 0.05), and the AgF group showed no significant difference from the PC group in the 50 µL group (p > 0.05). The FP group showed larger diameters than the AgF + KI group in the 30 µL (p = 0.009). The KI group did not show significant difference from the NC group (p > 0.05). AgF is comparable to ampicillin in antibacterial effects on S. mutans, and better than FP.

If welfare contracts are the solution – then what is the problem?
Authors: Foged Søren Kjær , Hjelmar Ulf , Jakobsen Mads Leth
Published: November 2022

The government, in collaboration with three municipalities, has established welfare contracts in elder care in the period 2021-2024. Through exemption from rules and greater room for maneuver for public employees, it is the ambition to develop new ways of governing the public sector as part of the so-called Subsidiarity Reform. We examine what governance problems employees and managers point to in the three municipalities. We analyze how large and uniform the problems are assessed to be and whether there are patterns in the problems. The article discusses whether the governance tools inherent in the welfare contracts are an obvious solution to the governance problems. The analysis is based on a survey among employees and immediate managers in the three municipalities with welfare contracts in elder care.
Respuesta social ante la aporofobia: retos en la intervención social
Authors: Picado Eva María , Yurrebaso Macho Amaia , Guzmán Ordaz Raquel
Published: November 2022

La aporofobia o aversión al pobre es un fenómeno discriminatorio que causa un gran daño social, de manera directa, a sus víctimas, dadas las consecuencias de la victimización sufrida, y a toda la comunidad en forma de deshumanización social que asume y normaliza dichas conductas. Este trabajo analiza la percepción social en relación con el conocimiento de la aporofobia y el impacto emocional que provocan los sucesos aporofóbicos en comparación con otros sucesos victimizantes. Se ha diseñado un cuestionario ad hoc en el que se diferencia, en una primera fase, la evaluación de conocimiento de la aporofobia, mientras que en una segunda se analiza el impacto emocional que provocan diferentes noticias, distinguiendo entre 1) situaciones con victimización aporofóbica real; 2) situaciones neutras donde a pesar de no haber victimización por aporofobia se publicitan apelando a denominaciones asociadas con estas conductas y grupo de personas, como puede ser «sin techo», indigente y/o vagabundo; y, por último, 3) situaciones que ni aluden ni se asocian con la aporofobia. En la investigación han participado voluntariamente 1.735 personas mayores de 18 años de las cuales el 56 % son mujeres. La edad de los participantes de distribuye en tres franjas: un 34,5 % entre 18 y 30 años; un 34,8 % entre 31 y 65 años, y un 30,7 % de personas mayores de 65 años. Los resultados demuestran un desconocimiento generalizado del concepto aporofobia y un mayor impacto emocional en los sucesos aporofóbicos a diferencia de otros sucesos, siendo significativamente mayor en el caso de las mujeres. Esta investigación evidencia la necesidad de diseñar acciones dirigidas a 1) informar de forma exhaustiva y real sobre el fenómeno; 2) concienciar sobre sus implicaciones y consecuencias, y 3) capacitar en la adquisición y desarrollo de competencias como la empatía, con el fin de crear una cultura de rechazo social hacia la aporofobia.
Effect of welded joint imperfection on the load-carrying capacity of pipe elbows subjected to in – plane bending moment
Authors: Medjo Bojan , Rakin Marko , Arsić Miodrag , Damnjanović Ivana , Stefanović Ana , Grabulov Vencislav
Published: November 2022

The defects in pipe elbows can, depending on their size and position, affect the integrity and safe service, as well as deformation ability of the piping systems in exploitation. Incompletely filled groove, which is the type of defect examined here, was observed by ultrasonic measurement on the pipeline in the regulation system of the hydro power plant Djerdap. Three-dimensional finite element analysis is performed using Simulia Abaqus software package. First, the models with dimensions of the defects observed by non-destructive examination are formed. Stress and strain fields for different loading types are shown and commented. The influence of the defect dimensions on the pipe elbow load-carrying capacity is determined through plastic collapse loads, which are obtained from bending moment - rotation angle diagrams. Twice elastic slope (TES) technique is applied. Additionally, some more severe defects are considered, in the form of sharp pre-cracks at the bottom of the defect; plastic collapse loads are also determined for these geometries. Both opening and closing bending moments are taken into consideration and the results are discussed and compared to two closed-form solutions from the literature.

The aim of this study was to evaluate the quality of dry-fermented pork sausages – “čajna” type from the market, with similar composition and different salt content. Physicochemical parameters of selected samples were determined and sensory quality parameters were evaluated. In samples M and D, with significantly higher (P ≤ 0.05) sodium chloride content, higher values of color parameter a* and breaking force and lower values of pH and water activity were found compared to samples T and L. Sample D had the highest protein (25.51%) and sodium chloride content (5.04%), and the lowest fat content (30.04%). Samples M and D had significantly higher sensory quality, especially odor, aroma, taste, consistency and cross-section, compared to other samples. These samples were evaluated as sausages with a pronounced pleasant aroma, taste and odor characteristic for dry-fermented products, with pleasant salinity, appropriate for the product. Although the dry-fermented sausage samples with a lower salt content had more acceptable nutritive values, their sensory quality was lower than expected.

Diabetes is a complex, chronic illness that demands a healthy diet. The overall quality of consumed food is important for diabetics, but benefits are expected from whole grains and lower-energy food. Choice of appropriate sweet bakery product may present the problem for diabetics in meal planning. The aim of this research is to provide an overview of some opportunities for new food product development for persons with diabetes and to analyze the risks associated with selected food ingredients, which can be used. It includes identification of special requirements for controlled nutrition. Quality parameters and food product composition are determined on a formulation for muffins modified to contain ingredients recommended and safe for diabetics’ diet with lower energy value, but keeping prescribed and acceptable product quality. The research focuses on assessment of the risks analysis associated with selected ingredients on an example of muffin-like cake formulation modelling and use of wheat flour, sugars, fats, salt and some additional ingredients, milk, eggs and cocoa powder, based on experience, insight into recommendations for diabetics’ nutrition and scientifically identified indicators aimed at health protection. Methodology for the selection of the ingredients for energy-reduced muffin-like cakes with whole-grain wheat flour and cocoa, suitable for diabetics’ diet presented in the paper, can be used as a model for developing other products aimed to improve nutrition of persons with healthy food preferences or diseases. In addition, it presents an opportunity for the food industry contribution to healthy lifestyle by developing products adapted to modern dietary recommendations and target consumers group.
A cooperative deep learning model for stock market prediction using deep autoencoder and sentiment analysis
Authors: Rekha KS , Sabu MK
Published: November 2022

Stock market prediction is a challenging and complex problem that has received the attention of researchers due to the high returns resulting from an improved prediction. Even though machine learning models are popular in this domain dynamic and the volatile nature of the stock markets limits the accuracy of stock prediction. Studies show that incorporating news sentiment in stock market predictions enhances performance compared to models using stock features alone. There is a need to develop an architecture that facilitates noise removal from stock data, captures market sentiments, and ensures prediction to a reasonable degree of accuracy. The proposed cooperative deep-learning architecture comprises a deep autoencoder, lexicon-based software for sentiment analysis of news headlines, and LSTM/GRU layers for prediction. The autoencoder is used to denoise the historical stock data, and the denoised data is transferred into the deep learning model along with news sentiments. The stock data is concatenated with the sentiment score and is fed to the LSTM/GRU model for output prediction. The model’s performance is evaluated using the standard measures used in the literature. The results show that the combined model using deep autoencoder with news sentiments performs better than the standalone LSTM/GRU models. The performance of our model also compares favorably with state-of-the-art models in the literature.

Russian wildrye, Psathyrostachys junceus (Fisch.) Nevski, is widely distributed in the high latitude areas of Eurasia. It plays an important role in grassland ecosystem maintenance, as well as being a valuable palatable forage species for livestock and wildlife. Russian wildrye germplasm has rich phenotypic and genetic diversity and has potential for improvement through crossbreeding. In this study, fifteen Russian wildrye hybrid combinations were produced and one F1 population with 123 putative hybrids was obtained by crossing two individual plants with significant differences in nutritional characteristics and reproductive tiller number. Twelve phenotypic traits of the F1 population were measured for three consecutive years, and ten of the twelve traits were in line with the genetic characteristics of quantitative traits. Hybrid superiority was revealed among F1 hybrids in both nutritional and reproductive traits. One non-recurrent parent plant with the highest PCA-synthesis score was selected and used to make a backcross with the ‘BOZOISKY SELECT’ male parent, and 143 putative BC1 hybrids were obtained. Sixteen pairs of EST-SSR primers were randomly selected from polymorphic primers derived from different expressed tiller trait related genes. Three primer pairs that amplified both the paternal and maternal characteristic band were used to assess the purity of the F1 population, and three primer pairs (with one shared primer pair) were used to identify the BC1 population. The hybrid purity was 96.75% for the F1 population and 95.80% for the BC1 population, and the results were confirmed by self-fertility test through bagging isolation. The genetic similarity coefficients between the F1 progeny and the male parent ranged from 0.500 to 0.895, and those between the BC1 progeny and the male parent ranged from 0.667 to 0.939. A subset of individuals in the BC1 population had closer genetic distance to the recurrent parent, and genetic variation within the BC1 population decreased compared to the F1 population.
Capital intelectual no contexto universitário: análise da literatura sob uma perspectiva construtivista

Published: November 2022

O objetivo deste artigo consiste em conhecer e analisar as características das publicações científicas que abordam o Capital Intelectual (CI) no contexto universitário, com base em uma perspectiva Construtivista. Por meio da abordagem qualitativa, realizou-se uma revisão sistemática da literatura orientada pelo instrumento de intervenção ProKnow-C. Isso possibilitou a seleção de um Portfólio Bibliográfico (PB), composto por 44 artigos, e conduziu a análise dos dados e a discussão dos achados pela operacionalização das etapas de (i) Construção do Mapa da Literatura; e (ii) Análise Bibliométrica. O Mapa da Literatura evidencia que essa linha de pesquisa se encontra em processo de crescimento, tanto sob o olhar interno quanto o externo. A ótica interna tratou, principalmente, da gestão, das ferramentas, dos sistemas de gestão e dos impactos da gestão do CI. Os estudos com olhar externo investigaram a divulgação do Capital Intelectual, a construção da imagem universitária, o relacionamento da Instituição de Ensino Superior (IES) com empresas e sociedade, e o reflexo do CI da IES no desenvolvimento regional que precisa ir além do atendimento de diretrizes dos rankings acadêmicos e atender aos stakeholders da Instituição e evidenciar que a sociedade é a principal parte interessada nessas informações. A Análise Bibliométrica evidenciou que o fragmento da literatura estudado ainda (i) é carente de investigadores que possuam essa temática como linha de pesquisa, e isso pode ter como consequência o comprometimento quanto ao desenvolvimento dessa temática; e (ii) está concentrado nos dois primeiros estágios da pesquisa de CI, necessitando, assim, avançar em relação aos três estágios seguintes.

Published: November 2022

High‐performance perovskite film with superior internal and surface qualities is critical for perovskite solar cells (PSCs) but hardly achievable due to the rapid crystallization rate of perovskite itself. Herein, a novel technique by in situ manipulating perovskite crystal growth and modifying the surface properties is developed using organic passivating agent‐assisted polydimethylsiloxane membrane as a facial mask (FM) of perovskites. By placing the perovskite‐precursor films with their faces toward the designed FM during thermal annealing, a favorable microenvironment is constructed for incubating high‐quality perovskite films with smooth surface, enhanced vertical orientation of (100) plane, and well‐adjusted interfacial energy levels. With this versatile FM incubation technique, efficient PSCs for both methylammonium (MA)‐based and formamidinium (FA)‐MA‐Cs mixed perovskite systems are facilely fabricated, delivering excellent humidity/thermal stabilities and promising efficiencies up to 21.4% with an improved open‐circuit voltage of 1.15 V in MA‐based devices. This study not only provides a facile and efficient approach to rationally manage the perovskite growth process, but also reveals the fundamental characteristics of high‐quality perovskite films comprehensively for the construction of efficient and stable PSCs.

Additive manufacturing (AM) is the key to creating a wide variety of 3D structures with unique and programmable functionalities. Direct ink writing is one of the widely used AM technologies with numerous printable materials. However, the extrude‐based method is limited by low fabrication resolution, which is confined to printing macrostructures. Herein, a new AM strategy is reported, using a low‐cost extrusion 3D printer, to create 3D microarchitectures at the macroscopic level through controlled desiccation of preprinted hydrogel scaffolds followed by infilling objective components. A printable hydrogel with a high‐water content ensures maximum shrinkage (≈99.5% in volume) of the printed scaffolds to achieve high resolution. Stable covalent cross‐linking and a suitable drying rate enable uniform shrinkage of the scaffolds to retain their original architectures. Particularly, this method can be adapted to produce liquid‐metal‐based 3D circuits and nanocomposite‐based microrobots, indicating its capability to fabricate functional and complex 3D architectures with micron‐level resolution from different material systems.
