Keserentakan Pemilu 2024 yang Paling Ideal Berdasarkan Putusan Mahkamah Konstitusi Republik Indonesia
Authors: Amir Mushaddiq
Published: May 2022

Terselenggaranya pemilu serentak pada tanggal 17 April 2019 merupakan sejarah baru dalam proses pemilihan umum yang ada di Indonesia. Hal ini merupakan implikasi dari Putusan Mahkamah Konstitusi Nomor 14/PUU/2013 perkara pengujian Undang-Undang Nomor 42 Tahun 2008 Tentang Pemilihan Umum Presiden dan Wakil Presiden. Meskipun pemilu serentak sudah dinilai lebih baik dari pemilu-pemilu sebelumnya bukan berarti dalam pelaksanaannya tidak memiliki kekurangan. Masalah yang paling menggemparkan adalah banyaknya korban jiwa oleh penyelenggara pemilu yang dinilai sebagai dampak pelaksanaan pemilu serentak 2019 serta masalah-masalah teknis lainnya. Melihat dari berbagai sisi yang ditimbulkan dari pemilu 2019, maka Perkumpulan Untuk Pemilu dan Demokrasi (Perludem) melakukan uji materiil Undang-undang terhadap Undang-Undang Dasar 1945 ke Mahkamah Konstitusi yang dituangkan kedalam Putusan Mahkamah Konstitusi Nomor 55/PUU-XVII/2019. Di dalam argumentasinya, pemohon menyampaikan beberapa hal terkait dengan analisa yang telah dilakukan dalam penyelenggaraan pemilu serentak yang dilaksanakan pada tahun 2019 kemarin. Dalam hasil keputusan tersebut, Mahkamah Konstitusi menolak permohonan pemohon untuk seluruhnya karena dianggap permohonan tersebut tidak beralasan hukum. Akan tetapi Mahkamah Konstitusi memberikan pilihan terkait model-model keserentakan pemilu yang dapat dipilih dan dinilai konstitusional berdasarkan UUD 1945.

Published: May 2022

Penelitian ini bertujuan untuk mengetahui kepastian dan perlindungan hukum terhadap jual beli di bawah tangan yang dilakukan oleh Kepala Adat atas tanah petuanan. Penelitian ini dilakukan dengan menggunakan metode penelitian hukum empiris dengan pendekatan undang-undang (statute approach) dan pendekatan konseptual (conceptual approach). Pengumpulan data dalam penelitian ini menggunakan teknik studi lapangan (field research) dan teknik studi pustaka (literature research). Data yang diperoleh baik data primer maupun data sekunder dianalisis secara kualitatif. Hasil penelitian menunjukkan bahwa tanah petuanan hanya dapat dikelola, dimiliki, dan pada prinsipnya dapat diserahterimakan atau diperjualbelikan kepada sesama anak-negeri. Adapun jual beli atas tanah petuanan harus dibuktikan dengan surat pelepasan hak dan surat keterangan yang diterbitkan oleh Kepala Adat. Selain itu, bagi warga yang bukan anak-negeri, apabila persyaratan materiil hubungan hukum jual beli atas tanah telah terpenuhi, maka jual beli tanah petuanan yang dilakukan oleh Kepala Adat sebagaimana berdasarkan prosedur hukum adat dinilai sah. Surat inilah yang menjadi bukti kepemilikan yang diakui oleh masyarakat hukum adat di Kota Ambon, meskipun surat tersebut menjadi akta di bawah tangan. Di sisi lain, surat pelepasan hak dan surat keterangan yang diterbitkan oleh Kepala Adat merupakan salah satu dokumen yang dipersyaratkan oleh BPN Kota Ambon untuk pendaftaran sertifikat hak milik atas tanah. Oleh karena itu, BPN perlu meningkatkan kesadaran hukum bagi pembeli tanah petuanan. Adapun bagi pihak pembeli tanah petuanan, perlu ditindaklanjuti di Kantor Pertanahan untuk segera mendaftarkan sertifikat hak milik atas tanah guna mengurangi risiko terjadinya tumpang tindih kepemilikan bahkan terjadinya sengketa atas tanah petuanan.

Published: May 2022

Plankton is composed by unicellular, filamentous or colonial organisms that may have prokaryotic or eukaryotic cell structures. These organisms have an extreme ecological importance in the different water bodies worldwide, as they fix carbon dioxide, produce oxygen and are an important key element in the basis of various food chains. Through an industrial perspective, phytoplankton species have been used as a feedstock for a wide range of applications, such as wastewater treatment, or production of high value compounds; and commercial products, such as food and feed supplements, pharmacological compounds, lipids, enzymes, biomass, polymers, toxins, pigments. Zooplankton is commonly used as live food for larval stages to the period of termination of fish, shrimp, mollusks and corals. These types of organisms have characteristics such as a valuable nutritional composition, digestibility, buoyancy, ease of ingestion and attractive movement for post-larvae, thus presenting economic importance. This book chapter aims to demonstrate the several advantages that plankton have, their ecological and economic importance, targeting the production of add-value products.

Authors: Xue Huali , Yang Zhimin
Published: May 2022

Dry rot of potato (Solanum tuberosum L.) is an important postharvest disease during storage. The decay can be caused by several different species of Fusarium spp., such as, F. sambucinum, F. coeruleum, F. oxysporum, F. avenaceum, F. culmorum. The pathogen of Fusarum spp. causing dry rot of potato is considerable different in different countries and regions. The typical symptom of potato dry rot is sunken and wrinkled brown to black tissue patch on tuber with less dry matter and shriveled flesh. Fusarium spp. only invades host through wound or natural orifice during pre-harvest, storage and transportation period. Some Fusarium species infection associated with mycotoxins accumulation, which has phytotoxicity and mycotoxicoses in humans and animals. Synthetic fungicide is the main strategy to control the dry rot of potato, however, there are series of problem, such as environmental pollution, pathogen resistance. An integrated approach to manage the disease includes the introduction of resistant cultivar, appropriate cultural practices, and storage conditions combined with the application of synthetic fungicides pre-harvest or post-harvest. Moreover, some chemical fungicides and microbial antagonists have been integrated into potato dry rot management.

Authors: Chellamuthu Muthulakshmi , Eswaran Kokiladevi , Subramanian Selvi
Published: May 2022

Genetic manipulation is a strong tool for modifying crops to produce a considerably wider range of valuable products which gratifies human health benefits and industrial needs. Oilseed crops can be modified both for improving the existing lipid products and engineering novel lipid products. Global demand for vegetable oils is rising as a result of rising per capita consumption of oil in our dietary habits and its use in biofuels. There are numerous potential markets for renewable, carbon-neutral, ‘eco-friendly’ oil-based compounds produced by crops as substitutes for non-renewable petroleum products. Existing oil crops, on the other hand, have limited fatty acid compositions, making them unsuitable for use as industrial feedstocks. As a result, increasing oil output is necessary to fulfill rising demand. Increasing the oil content of oilseed crops is one way to increase oil yield without expanding the area under cultivation. Besides, the pharmaceutical and nutraceutical values of oilseed crops are being improved by genetic engineering techniques. This chapter addresses the current state of the art gene manipulation strategies followed in oilseed crops for oil modification to fulfill the growing human needs.

Authors: Ebrahimi Mehrdad , Nemati Eghlim , Esmaeili Davoud
Published: May 2022

Background: Legionella is a fastidious Gram-negative bacterium that is responsible for Legionnaires’ disease. Legionella is a ubiquitous aquatic bacterium, especially in cooling systems. Several studies have investigated Legionella contamination in natural and man-made water resources. Legionella is resistant to chlorine and other disinfectants; thus, it is important to consider it in places where people with immunodeficiency are kept. Objectives: The aim of this study was to detect the Legionella pneumophila mip gene in clinical samples, kidney transplants, and dialysis wards by the polymerase chain reaction (PCR) method. Methods: In this study, 156 samples were taken from the kidney transplant and dialysis wards. DNA extraction was done. After confirmation of primers, PCR was performed to amplify 16srRNA and mip genes. The PCR product was electrophoresed on agarose gel 1%. Results: Among the samples, 23 samples were infected with Legionella (14.7%), of which 7 samples were identified for the mip gene (4.5%) and 16 samples for 16srRNA (10.2%). The confirmation of the presence of these genes was done by sequencing. In serum, tissue, urine, hot water, and cold water samples were positive for the 16srRNA gene (7.5%, 26.66%, 7.14%, 20%, and 6.66%, respectively). Among these samples, 50% of tissue samples, 25% of urine, and 33.33% of hot water were positive for the mip gene. Conclusions: The presence of L. pneumophila in aqueous samples of transplant and dialysis wards is important. Therefore, rapid detection of this bacterium or the mip gene by a molecular method can play an important role in reducing infection and transplant rejection.

O estado do Piauí possui uma rica Geodiversidade em ambientes naturais passíveis de inúmeras investigações em diversas áreas do conhecimento, sobretudo no campo da Geografia Física. Dessa forma, a existência de estudos que se debruçaram nesta temática auxiliando, assim, no avanço científico e descobertas de novas realidades locais, diante disso, o presente estudo objetiva realizar um levantamento teórico, metodológico e espacial dos estudos sob interpretação da Geografia Física do Piauí a partir de eventos locais realizados entre 2013 e 2018. Caracterizado como Estado da Arte, este estudo analisou 240 trabalhos publicados em anais de 11 eventos científicos, sob abordagem quali-quantitativa e com utilização do software QGis (3.16, versão Hannover) para distribuição espacial dos estudos em Regiões Geográficas Intermediárias (6) e Imediatas (19). Os resultados alcançaram que, dentre as 11 categorias/temas de estudos, destacaram-se quantitativamente aqueles relacionados a Impactos Socioambientais, Geografia Física e Ensino e Outros, com 55, 39 e 35 estudos, respectivamente. Da mesma forma, no tangente aos procedimentos metodológicos, a adoção de Análises Bibliográficas/Documentais e Estudos de Campo foram consenso com 240 e 135 aplicações, respectivamente, com forte carga teórica da abordagem sistêmica. No contexto da distribuição espacial dos estudos, estes se concentram em grande parte na porção Centro-Norte piauiense, principalmente nas Regiões Geográficas Intermediárias e Imediatas de Teresina e Parnaíba, bem como a ausência de estudos nas Regiões Geográficas Imediatas de Oeiras, Simplício Mendes e Corrente, concluindo, assim, que há uma distribuição muito desigual de realização de estudos em detrimento a determinadas regiões, mesmo que, ricas em possibilidades analíticas.

Authors: Salvador Diego Salomão Candido de Oliveira , Matias Ellano Jonh da Silva
Published: May 2022

Desde a segunda metade do século XX, com a Revolução Técnico-Científica-Informacional, a produção do espaço geográfico é cada vez mais caracterizada pelos usos das variáveis-chave técnica, ciência, informação, consumo e finanças. Na Educação, detidamente, o processo de ensino-aprendizagem é marcado pelas tecnologias digitais da informação e comunicação (TDIC). Diante disso, o docente não deve negligenciar o fato de que as TDIC fazem parte do cotidiano do estudante e, dessa maneira, podem ser usadas como estratégias para a amplificação da aprendizagem na esteira do destaque do discente enquanto protagonista do processo educacional. Para isso, é necessário que o docente conheça a cibercultura e participe dela, incluindo na sua prática profissional o uso das TDIC, de acordo com as possibilidades infraestruturais e socioeconômicas da escola e da comunidade envolvidas no processo educacional. Para o ensino-aprendizagem de Geografia na Educação Básica, especificamente, no Ensino Fundamental II, acreditamos que os usos das TDIC podem significar em estratégias metodológicas para a compreensão de conteúdos fundamentais ao entendimento da dinâmica do espaço no que tange às variadas escalas geográficas. Dentre estes conteúdos, sublinhamos o da alfabetização cartográfica, que é a aprendizagem das noções de localização, organização e representação do espaço, como produto e condição das ações humanas e relações sociais. Sendo assim, neste trabalho objetivamos analisar as possibilidades da utilização do software Google Earth Pro para o ensino-aprendizagem de Geografia no Ensino Fundamental II, notadamente, quanto ao entendimento da representação cartográfica do espaço geográfico. Concluímos que, para o ensino-aprendizagem de Geografia, esse software pode ser uma importante ferramenta didático-pedagógica, útil para o desenvolvimento de processo educacional dinâmico, ativo e contextualizado no que se refere a conteúdos como o da (re)produção do espaço e o da linguagem cartográfica.

The purpose of the study is to describe the current processes taking place today in the field of information/communication technologies in generally understandable terms to form an overall picture; analysis of these results; forecast of development. The object of research is a modern society on a global scale. The article analyzes the main trends of information strategies, technical innovations in the field of communications, clarifies terminology on this topic. The methodological basis of the research is both general scientific and traditional methods used in political science and economics, using new terminology describing modernity – analysis, synthesis, comparative methods, etc. The main conclusions of the study are the thesis about the beginning of a gradual change in modern society through minor but permanent changes in the modern social contract with the help of new information technologies, as well as about the opacity of such a system. The scientific novelty is represented by the analysis of the concept of an immersive virtual environment that is actively developing today - the metaverse, which today is often called the Internet 2.0. Also, on the basis of primary sources – publications on this topic since the end of the twentieth century and up to modern publications, the terminology in this area has been clarified and systematized. The article points out the existence of a certain contradiction, a conflict inherent in new technologies, from the point of view of political philosophy.
Notch-dependent and -independent transcription are modulated by tissue movements at gastrulation
Authors: Falo-Sanjuan Julia , Bray Sarah
Published: May 2022

Cells sense and integrate external information from diverse sources that include mechanical cues. Shaping of tissues during development may thus require coordination between mechanical forces from morphogenesis and cell-cell signalling to confer appropriate changes in gene expression. By live-imaging Notch-induced transcription in real time, we have discovered that morphogenetic movements during Drosophila gastrulation bring about an increase in activity-levels of a Notch-responsive enhancer. Mutations that disrupt the timing of gastrulation resulted in concomitant delays in transcription up-regulation that correlated with the start of mesoderm invagination. As a similar gastrulation-induced effect was detected when transcription was elicited by the intracellular domain NICD, it cannot be attributed to forces exerted on Notch receptor activation. A Notch-independent vnd enhancer also exhibited a modest gastrulation-induced activity increase in the same stripe of cells. Together, these observations argue that gastrulation-associated forces act on the nucleus to modulate transcription levels. This regulation was uncoupled when the complex linking the nucleoskeleton and cytoskeleton (LINC) was disrupted, indicating a likely conduit. We propose that the coupling between tissue-level mechanics, arising from gastrulation, and enhancer activity represents a general mechanism for ensuring correct tissue specification during development and that Notch-dependent enhancers are highly sensitive to this regulation.
Seipin transmembrane segments critically function in triglyceride nucleation and lipid droplet budding from the membrane

Published: May 2022

Lipid droplets (LDs) are organelles formed in the endoplasmic reticulum (ER) to store triacylglycerol (TG) and sterol esters. The ER protein seipin is key for LD biogenesis. Seipin forms a cage-like structure, with each seipin monomer containing a conserved hydrophobic helix and two transmembrane (TM) segments. How the different parts of seipin function in TG nucleation and LD budding is poorly understood. Here, we utilized molecular dynamics simulations of human seipin, along with cell-based experiments, to study seipin’s functions in protein–lipid interactions, lipid diffusion, and LD maturation. An all-atom simulation indicates that seipin TM segment residues and hydrophobic helices residues located in the phospholipid tail region of the bilayer attract TG. Simulating larger, growing LDs with coarse-grained models, we find that the seipin TM segments form a constricted neck structure to facilitate conversion of a flat oil lens into a budding LD. Using cell experiments and simulations, we also show that conserved, positively charged residues at the end of seipin’s TM segments affect LD maturation. We propose a model in which seipin TM segments critically function in TG nucleation and LD growth.
Malware detection framework based on graph variational autoencoder extracted embeddings from API-call graphs
Authors: Gunduz Hakan
Published: May 2022

Malware harms the confidentiality and integrity of the information that causes material and moral damages to institutions or individuals. This study proposed a malware detection model based on API-call graphs and used Graph Variational Autoencoder (GVAE) to reduce the size of graph node features extracted from Android apk files. GVAE-reduced embeddings were fed to linear-based (SVM) and ensemble-based (LightGBM) models to finalize the malware detection process. To validate the effectiveness of the GVAE-reduced features, recursive feature elimination (RFE) and Fisher score (FS) were applied to select informative feature sets with the same sizes as GVAE-reduced embeddings. The results with RFE and FS selections revealed that LightGBM and RFE-selected 50 features achieved the highest accuracy (0.907) and F-measure (0.852) rates. When we used GVAE-reduced embeddings in the classification, there was an approximate increase of %4 in both models’ accuracy rates. The same performance increase occurred in F-measure rates which directly indicated the improvement in the discrimination powers of the models. The last conducted experiment that combined the strengths of RFE selection and GVAE led to a performance increase compared to only GVAE-reduced embeddings. RFE selection achieved an accuracy rate of 0.967 in LightGBM with the help of selected 30 relevant features from the combination of all GVAE-embeddings.

Published: May 2022

COVID-19, caused by a novel coronavirus named SARS-CoV-2 was reported in December 2019, which equitably brought the entire world to a standstill, affecting the market, consumer demand, purchase decisions, and the global supply chain. A critical situation pushes human behavior in different directions, and COVID 19 is one such situation that is not normal. To control the spread of disease, all the countries, including India, imposed the lockdown, resulting in market stagnation, economic instabilities, and changes in consumers' purchasing patterns related to various products. The present study investigates the consumers’ behavioral intentions amid COVID-19 in the context of apparel. The present study attempts to identify the clothing preferences of consumers during the pandemic by exploring the factors playing a crucial role while buying clothing during the COVID pandemic, by examining the links between consumer buying behavior of apparel during normal times and in crisis by elaborate literature as well as consumer survey. The research helped understand consumers' clothing type preferences as well as their sources of information on the latest fashion trends during Covid. The researcher also explored other factors that play a crucial role in buying clothing during COVID. The results revealed that online shopping had a positive influence during the pandemic, with social media being the most significant influencer for the latest fashion trends. During the lockdown, “work from home” leads to the comfort factor playing a substantial role while purchasing apparel. Consumer sentiments were also explored in the study, and it was found that consumers visit less to malls and prefer online purchases due to contactless shopping. They enjoy online shopping because of its ease and convenience.

Introduction: In general, the creation system in Brazil has been characterized as an activity of great importance in the socio-economic market, as it generates employment and income opportunities.

Aims: This work aims to carry out a brief bibliographical review regarding the use of sustainability indicators within the creation systems.

Literature Review: The notion of sustainability is still a recent term and is under construction. Among the countless concepts of sustainability found in specialized literature, sustainability means the "possibility of continuously obtaining equal or superior conditions of life for a group of people and their successors in a given ecosystem. On the other hand, the concept of indicators, as well as for the concept of sustainability does not have a universal definition. Sustainability indicator “is an instrument that allows, based on its interpretation, to define the condition of a system as sustainable or not.” In other words, sustainability indicators can be understood as parameters, in which the assessment shows whether the limit, established according to the values ​​and objectives that govern a given reality, was exceeded or respected.

This study aimed to determine the influence of socio-demographic and economic factors on youth alcohol abuse in Rombo District. Questionnaires, Focus Group Discussions (FGDs) and Key-Informant Interviews were used for data collection. Quantitative data were analysed by Statistical Product for Social Solutions (SPSS Version 20) while textual data was analysed by thematic analysis. The study revealed that parents and peer groups have influence on youth alcohol abuse, alcohol accessibility and affordability by youths and that alcohol prices are affordable to almost everyone have influence to youth alcohol abuse. The study findings depict that existence of many types of locally brewed alcohol and many registered and unregistered alcohols selling points contribute to youth alcohol abuse. The study concludes that proper family characters aiming at curbing alcohol abuse among youth are of paramount importance, as most youth learn to drink at their young age. The study recommends that the government should enforce regulations related to alcohol use, especially that concerning selling of alcohol to the under age, as well on existences several local brews of which most of them being illegal and control of unregistered alcohol selling points is mostly challenging task, the government should impose tax on locally brewed alcohol to increase their prices, as they are so cheap, family heads and elders should be role models by controlling their drinking behaviours, especially drinking with/in presence of their children. Moreover, they should restrict their youth from drink alcohol and there should be strong punishment for under age selling and drinking of alcohol.

Published: May 2022

In Africa, bushfires are common practices in savannah regions. Their impact, is the subject of many scientific debates. The protected areas, of North Cameroon are subjected to ambivalent effects of these fires. Using high-resolution remote sensing data, this work aims at assessing burned areas at the interannual and intraannual scale in order to explain the complex environmental dynamics of landscapes, to contribute to fire management in a context of protected areas. To achieve this, time series of sentinel-2 images from the Multi Spectral Instrument from the year 2015-2020 have been used. By the unitemporal and multitemporal methods, the development of spectral indices has made it possible to locate the burned surfaces and to determine the periods of the fires. Observations and field surveys aimed to understand the factors of fires using, their typology as well as the roles of the actors. The findings show that each spectral index has its own ability to detect burnt surfaces: The NDVI can detect fires only at the start of the dry season, the SAVI is suitable for identifying intermediate and late fires, while the NBR is best suited for separating burnt and unburnt surfaces throughout the season, regardless of the method employed. Depending on their periods of occurrence, the fires spread more in parks with a fairly extensive grass cover compared to overexploited ordinary areas. They then depend on socio-environmental factors, namely the state of land used, the continuity of the herbaceous cover and the social practices in place. The mapping and monitoring of burned surfaces by remote sensing therefore constitute a tool and a method for diagnosing the state of the herbaceous plant cover and for managing natural resources.

Background: The increase in prevalence of antimicrobial-resistant bacteria (ARB) is currently a serious threat, thus there is a need for new classes antimicrobial compounds to combat infections caused by these ARB. The growth inhibition ability of derivatives of the components of nucleic acids has been well-characterized but not for its antimicrobial characteristics.

Aims: To evaluate in vitro antimicrobial activity profile of modified pyrimidine nucleosides derivatives.

Methodology: Modified nucleosides arabinofuranosylcytosine (cytarabine, ara-C), [1-(2',3',5'-tri-O-acetyl-β-D-ribofuranosyl)-4-(1,2,4-triazol-1-yl)]uracil (TTU), and nucleotides cytarabine-5′-monophosphate (ara-CMP), and O2,2′-cyclocytidine-5′-monophosphate (cyclocytidine monophosphate, cyclo-CMP) were synthetized and subsequentially checked for antibacterial activity. Bacterial cells characteristics were assessed by antiproliferative and the production of intracellular reactive oxygen species (ROS) assays.

Results: It was found that modified nucleosides ara-C, and TTU, and nucleotides ara-CMP, and cyclo-CMP were able to inhibit Escherichia coli, Sarcina lutea, Bacillus cereus, and Proteus mirabilis strains in a time and dose dependent manner via killing kinetics assay. Gram-negative (E. coli and P. mirabilis) bacteria stains were more sensitive to the exposure of TTU and cyclo-CMP and less sensitive to the exposure of ara-C and ara-CMP compared to gram-positive ones. The most effective cells growth inhibitor for gram-positive strains (S. lutea, B. cereus) was ara-CMP with ED50 = 5.2•10-5 M and 3.1•10-4 M, respectively. Sarcina lutea appeared to be the most sensitive bacteria strain to the exposure of all studied compounds. It was demonstrated that studied modified pyrimidine nucleosides derivatives enhanced the production of intracellular ROS over time (validated via DCFA-DA probe assay).

Conclusion: This study has revealed the mechanism of action of cytarabine, cyclocytidine monophosphate, and TTU as an antimicrobial agent for the first time, and has shown that these pyrimidine derivatives enhanced might be able to combat infections caused by Escherichia coli, Sarcina lutea, Bacillus cereus, and Proteus mirabilis in the future.

Authors: Nguyen Thi Tu Anh , Vu Anh- Tuan
Published: May 2022

In this study, ZnO/g-C3N4 nanocomposites were prepared via a physical mixing-calcination process for improved degradation of dyes under visible light irradiation. The BET surface area, pore volume, crystal size, and pHpzc of the ZnO/g-C3N4 composite were 3.9 m2/g, 0.034 cm3/g, 18.1 nm, and 7.7, respectively. Although the morphology of the ZnO/g-C3N4 composite was very different from that of pure g-C3N4, their average pore sizes were similar. The Eg of the ZnO/g-C3N4 composite (3.195 eV) was slightly lower than that of ZnO (3.195) but much higher than that of g-C3N4 (2.875). The interface interaction of ZnO and g-C3N4, which was revealed by oscillations of Zn-C, benefited the transport of photoinduced charge carriers and reduced the recombination of electron-hole. As the result, the ZnO/g-C3N4 composite had higher photocatalytic activity than ZnO and g-C3N4. Its degradation efficiency (DE) value for methylene blue (MB) in 90 min and rate constant were 93.2 % and 0.025 min‑1, respectively. In addition, the effects of ZnO/urea molar ratio, catalyst dosage, solution pH, and concentration of dye on photocatalytic degradation of MB were completely investigated. The photocatalytic performance of the ZnO/g-C3N4 composite was evaluated by the degradation of other persistent organic compounds, also compared to other catalysts in the literatures.

Surface oxygen vacancies have been widely discussed to be crucial for tailoring the activity of various chemical reactions from CO, NO, to water oxidation by using oxide‐supported catalysts. However, the real role and potential function of surface oxygen vacancies in the reaction remains unclear because of their very short lifetime. Here, it is reported that surface oxygen vacancies can be well confined electrostatically for a polarization screening near the perimeter interface between Pt {111} nanocrystals and the negative polar surface (001) of ferroelectric PbTiO3. Strikingly, such a catalyst demonstrates a tunable catalytic CO oxidation kinetics from 200 °C to near room temperature by increasing the O2 gas pressure, accompanied by the conversion curve from a hysteresis‐free loop to one with hysteresis. The combination of reaction kinetics, electronic energy loss spectroscopy (EELS) analysis, and density functional theory (DFT) calculations, indicates that the oxygen vacancies stabilized by the negative polar surface are the active sites for O2 adsorption as a rate‐determining step, and then dissociated O moves to the surface of the Pt nanocrystals for oxidizing adsorbed CO. The results open a new pathway for tunable catalytic activity of CO oxidation.

Published: May 2022

Tuning the reactivity of lattice oxygen is of significance for lowering the energy barriers and accelerating the oxygen evolution reaction (OER). Herein, single‐atomic Mo sites are anchored on Ni–Fe oxyhydroxide nanoarrays by a facile metal–organic‐framework‐derived strategy, exhibiting superior performance toward the OER in alkaline media. In situ electrochemical spectroscopy and isotope‐labeling experiments reveal the involvement of lattice oxygen during OER cycles. Combining theoretical and experimental investigations of the electronic configuration, it is comprehensively confirmed that the incorporation of single‐atomic Mo sites enables higher oxidation state of the metal and strengthened metal–oxygen hybridization, as well as the formation of oxidized ligand holes above the Fermi level. In a word, the considerable acceleration of water oxidation is achieved via enhancing the reactivity of lattice oxygen and triggering the lattice oxygen activation. This work may provide new insights for designing ideal electrocatalysts via tuning the chemical state and activating the anions ligands.
An Open‐Environment Tactile Sensing System: Toward Simple and Efficient Material Identification
Authors: Wei Xuelian , Wang Baocheng , Wu Zhiyi , Wang Zhong Lin
Published: May 2022

Robotic perception can have simple and effective sensing functions that are unreachable for humans using only the isolated tactile perception method, with the assistance of a triboelectric nanogenerator (TENG). However, the reliability of triboelectric sensors remains a major challenge due to the inherent environmental limitations. Here, an intelligent tactile sensing system that combines a TENG and deep‐learning technology is proposed. Using a triboelectric triple tactile sensor array, typical characteristics of each testing material can be maintained stably even under different contact conditions (touch conditions and external environmental conditions) by extracting features from three independent electrical signals as well as the normalized output signals. Furthermore, a convolutional neural network model is integrated, and a high accuracy of 96.62% is achieved in a material identification task. The tactile sensing system is exhibited to an open environment for material identification and the real‐time demonstration. Compared to the complex process that humans must integrate multiple sensing (touching and viewing) to accomplish tactile perception, the proposed sensing system shows a huge advantage in cognitive learning for the visually impaired, biomimetic prosthetics, and virtual spaces construction.
Bias‐Triggered Conductivity Switching and High Effective Rectification in Metallocene‐Based Molecular Junctions
Authors: Asyuda Andika , Das Saunak , Lang Heinrich , Zojer Egbert , Zharnikov Michael
Published: May 2022

Molecular diodes usually exhibit fixed current values at a specific bias and achieve sizable rectification ratio (RR) at voltages of ≈1.0 V. Here, a series of custom‐designed molecular films of ferrocenyl/ruthenocenyl‐substituted biphenylthiolates and fluorenethiolates on Au (111) is presented, which exhibit a distinctly different behavior. When embedded into two‐terminal junctions, they show two different conduction states, with a high conductivity state at a negative bias and a low conductivity state upon applying a sufficiently high positive bias. Comparing the current values for these two states, an effective RR of more than 1000 is obtained, a value comparable to the best performing molecular diodes but attained already at particularly low voltages. Significantly, the switching between the conduction states is reversible and the initial, high conductivity state can be recovered by the application of a negative bias. The proposed explanation for these observations is the bias‐induced switching of the junction to a metastable state comprising oxidized ferrocenyl/ruthenocenyl entities, which are characterized by less delocalized frontier orbitals and cause the formation of a significant potential barrier within the junction. It is hypothesized that this state can be stabilized by structural changes in the monolayers, affecting also their coupling to the top electrode.
