This study aimed to analyze the effect of material mastery on the pre-service teachers’ teaching readiness of Freedom to Learn-Independent Campus (MBKM) in teaching assistance of the economic education study program at Universitas Tanjungpura. The background of this study was many pre-service teachers in economics education study programs still experience unpreparedness in carrying out learning activities in class while participating in teaching assistance. This study used a quantitative approach with a causal method. The study population consisted of 90 pre-service teachers with a sample of 50 pre-service teachers and used a simple random sampling technique. The results showed that material mastery did not affect the readiness to teach in the teaching assistance of the MBKM program in the economics education study program, with a significance value of 0.587 > 0.05. Based on the results of this study, it can be concluded that mastery of the material does not affect the readiness to teach for pre-service teachers in teaching assistance of the MBKM program.

La kombucha es una bebida fermentada formada de una simbiosis de bacterias y levaduras compuesta mediante la infusión de hojas de té por fermentación de sustratos azucarados que forman una masa gelatinosa de celulosa bacteriana en la parte superior de la bebida, denominada SCOBY (Cultivo Simbiótico de Bacterias y Levaduras). Actualmente, existen variaciones de kombucha realizadas con adición de jugos de frutas, leche, etc, lo que ocasiona que hoy en día se busquen diferentes sustratos. El objetivo de ésta investigación fue evaluar el comportamiento del pH, acidez y grados brix de un fermentado no alcohólico elaborado a partir de diferentes combinaciones de sábila y moringa. Se realizaron 11 tratamientos con diferentes concentraciones de moringa, dextrosa y sábila a los cuales se les determinó pH, acidez y turbidez durante los 12 días de fermentación. Los tratamientos T3, T4, T7 y T8 obtuvieron un pH de 4.7-7.0 y una acidez de 1.2-1.6%. El resto de los tratamientos obtuvieron valores de pH bajos de 3.2, favoreciendo la producción de altas concentraciones de ácidos orgánicos. La turbidez no mostró cambios significativos durante la fermentación. La menor concentración de moringa y la combinación de dextrosa y sábila en la misma proporción favorecieron las mejores condiciones de pH y acidez para la fermentación de la kombucha.

В статье изучено напряженно-деформированное состояние (НДС) предварительно напряженной железобетонной балки прямоугольного сечения с привлечением методов конечно-элементного анализа на базе вариационной формулировки. Железобетонная балка рассмотрена в виде неоднородного конечного элемента, причем матрица жесткости представляет суммарную матрицу жесткостей, т.е. бетона и арматурных стержней. Для расчета использован метод решения физически нелинейных задач, т.е. шаговый метод приращения нагрузки в комбинации с абсолютно устойчивой итерационной схемой Ньютона-Рафсона. Сформулированы расчетный алгоритм и методика формирования матриц балочного железобетонного элемента с учетом трещин. Модуль упругости арматуры заменен касательным модулем арматуры для тех элементов, которые имеют трещины. Многовариантные численные эксперименты сопровождались определением прогибов в среднем сечении балки, а также изучением зон формирования и развития трещинообразования. Исследовано НДС железобетонных конструкций в момент возникновения трещин в бетоне и появления пластических деформаций в арматуре на стадии проектирования. Анализ полученных результатов НДС показывает, что предлагаемый метод позволяет проследить за трещиностойкостью и жесткостью железобетонных балок на всех этапах нагружения.

Multiple Stimuli‐Responsive Luminescent Chiral Hybrid Antimony Chlorides for Anti‐Counterfeiting and Encryption Applications

Published: July 2023

AbstractStimuli‐responsive circularly polarized luminescence (CPL) materials are ideal for information anti‐countering applications, but the best‐performing materials have not yet been identified. This work presents enantiomorphic hybrid antimony halides R‐(C5H12NO)2SbCl5 (1) and S‐(C5H12NO)2SbCl5 (2) showing mirror‐imaged CPL activity with a dissymmetry factor of 1.2×10−3. Interestingly, the DMF‐induced structural transformation is realized to obtain non‐emissive R‐(C5H12NO)2SbCl5 ⋅ DMF (3) and S‐(C5H12NO)2SbCl5 ⋅ DMF (4) upon exposure to DMF vapor. The transformation process is reversed upon heating. DFT calculations showed that the DMF‐induced‐quenched‐luminescence is attributed to the intersection of the ground and excited state curves on the configuration coordinates. Unexpectedly, the nanocrystals of the chiral antimony halides 1 and 2 were prepared and indicate the excellent solution process performance. The reversible PL and CPL switching gives the system applications in information technology, anti‐counterfeiting, encryption‐decryption, and logic gates.

AbstractAchieving both high open‐circuit voltage (Voc) and short‐circuit current density (Jsc) to boost power‐conversion efficiency (PCE) is a major challenge for organic solar cells (OSCs), wherein high energy loss (Eloss) and inefficient charge transfer usually take place. Here, three new Y‐series acceptors of mono‐asymmetric asy‐YC11 and dual‐asymmetric bi‐asy‐YC9 and bi‐asy‐YC12 are developed. They share the same asymmetric D1AD2 (D1=thieno[3,2‐b]thiophene and D2=selenopheno[3,2‐b]thiophene) fused‐core but have different unidirectional sidechain on D1 side, allowing fine‐tuned molecular properties, such as intermolecular interaction, packing pattern, and crystallinity. Among the binary blends, the PM6 : bi‐asy‐YC12 one has better morphology with appropriate phase separation and higher order packing than the PM6 : asy‐YC9 and PM6 : bi‐asy‐YC11 ones. Therefore, the PM6 : bi‐asy‐YC12‐based OSCs offer a higher PCE of 17.16 % with both high Voc and Jsc, due to the reduced Eloss and efficient charge transfer properties. Inspired by the high Voc and strong NIR‐absorption, bi‐asy‐YC12 is introduced into efficient binary PM6 : L8‐BO to construct ternary OSCs. Thanks to the broadened absorption, optimized morphology, and furtherly minimized Eloss, the PM6 : L8‐BO : bi‐asy‐YC12‐based OSCs achieve a champion PCE of 19.23 %, which is one of the highest efficiencies among these annealing‐free devices. Our developed unidirectional sidechain engineering for constructing bi‐asymmetric Y‐series acceptors provides an approach to boost PCE of OSCs.
Tailoring polyamide 6 to exhibit super‐tough behavior and high thermomechanical stability: The role of AES and EPDM‐MA hybridization

Published: July 2023

AbstractHigh‐performance blends based on polyamide 6 (PA6) were prepared using a hybrid mixture of acrylonitrile/EPDM/styrene (AES) and maleic anhydride grafted ethylene–propylene–diene (EPDM‐MA). Samples were processed in a twin‐screw extruder and injection molded. The torque curves of the PA6/AES/EPDM‐MA blends shifted to higher torque values with added EPDM‐MA, suggesting a chemical interaction between the components. The melt flow index (MFI) results for the PA6/AES/EPDM‐MA blends confirmed the intensification of the flow resistance. Intense infrared absorption peaks for NH and CO indicated that the amine groups of PA6 reacted with the maleic anhydride in EPDM‐MA. The 60/25/15 wt% PA6/AES/EPDM‐MA blend showed an impact strength over 800 J/m, heat deflection temperature (HDT) of 62.3°C, elongation at break of 115%, and contact angle of 59.1°, corresponding to increases of 1718%, 10.5%, 297%, and 10%, respectively, compared to neat PA6. When examined by scanning electron microscopy, the morphology showed a fracture surface with a high degree of plastic deformation and the formation of elastic microfibrils, contributing to the super toughening of the PA6/AES/EPDM‐MA (15%) system. These results indicate the technological potential of the PA6/AES/EPDM‐MA (15 wt%) blends for application in industrial sectors that require super‐tough plastics.
