Following the remarkable advances in the performance of metal halide perovskite solar cells, recent research efforts have focused more on enhancing their long-term stability. Among the various factors that impact the device’s lifetime, humidity-driven degradation plays an important role and can significantly lower the device performance within hours. It is ge...
Continue readingSimultaneous two-photon imaging and electrophysiological recordings offer considerable potential for advancing neurological research and therapies. However, traditional metal-based neural interfaces suffer from photoelectric artifacts, while existing transparent implants rely on opaque interconnect lines to address conductivity limitations. Herein, we developed a...
Continue readingWastewater pollution caused by toxic dyes from the textile industry is a global challenge, threatening agricultural productivity, food security, and access to clean water for livestock. In recent years, photocatalytic degradation of organic pollutants using semiconducting materials has emerged as a promising approach for sustainable wastewater treatment. We prese...
Continue readingProteins harboring intrinsically disordered regions (IDRs) lacking stable secondary or tertiary structures are abundant across the three domains of life. These regions have not been systematically studied in prokaryotes. Here, our genome-wide analysis identifies extracytoplasmic serine/threonine-rich IDRs in several biologically important membrane-associated prot...
Continue readingThere is a tremendous upsurge in lung cancer incidences due to changing lifestyles and other environmental risk factors. Unfortunately, the use of clinical therapeutics is causing serious side effects and drug-resistant tumors. Taking account of the severity of lung cancer malignancy and the pressing need for natural therapeutics, we investigated the anticancer p...
Continue readingMicro-nano plastics have emerged as a major ecological concern. The nanoplastics (NPs) pose a huge threat to microscopic animals. Our study aims to decipher the effect of polystyrene nanoplastics (PSNPs) of 50 and 100 nm sizes on a bdelloid rotifer (Philodina roseola). Both sizes of PSNPs were analyzed using field emission Scanning electron microscopy, Fourier tr...
Continue readingThe use of eutectic gallium indium (EGaIn) liquid metal alloy as anodes for lithium-ion batteries (LIBs) has been extensively studied owing to its shape-deformable and self-healing properties. However, to limit the damage to EGaIn anodes resulting from volume expansion during lithiation and delithiation, chemical modifications are required to stabilize the liquid m...
Continue readingThe treatment of volumetric muscle loss (VML) is challenging owing to the deficiency of appropriate bioscaffolds and ineffective therapeutic outcomes with conventional approaches. Adhesive hydrogels have emerged as potential tools for promoting tissue regeneration, offering effective integration with damaged tissues. However, technical procedures requiring non-bioc...
Continue readingThis study successfully synthesized sheet-like triangular Bi2O3 using the hydrothermal method and subsequently annealed it in a hydrogen-contained atmosphere to effectively introduce oxygen vacancies. ZnO was fabricated through sputtering at elevated substrate temperatures, which also facilitated the formation of oxygen vacancies. We prepared Bi2O3/ZnO composites t...
Continue readingThe contamination of the endoscope tip lens results in poor endoscopic imaging. To prevent the adsorption of contaminants, we applied a soft contact lens made of 2-hydroxyethyl methacrylate hydrogel to the tip of a gastrointestinal endoscope. Additionally, a novel endoscopic hood with an upper surface composed of a single layer inside the hood cavity was develope...
Continue readingThe amplification of molecular motion along length scales for macroscopic muscle-like functions, based on supramolecular polymers, provides attractive opportunities ranging from soft actuators to responsive biomedical materials. Taking the challenge to reveal dynamic assembly parameters governing muscle functions, we present the design of a photoswitch amphiphile...
Continue readingAnalysis of the secondary metabolite biosynthesis gene cluster (BGC) from marine Streptomyces sp. SNJ102 revealed the presence of a noncanonical nonribosomal peptide synthetase (NRPS), predicted to produce a depsipeptide compound. The NRPS gene cluster was captured by transformation-associated recombination and heterologously expressed in Streptomyces albus. The ...
Continue readingIron uptake in plants is negatively regulated by highly conserved hemerythrin (Hr) E3 ubiquitin ligases exemplified by Arabidopsis thaliana BRUTUS (BTS). Physiological studies suggest these are the elusive plant iron sensors, but biochemical evidence is lacking. Here we demonstrate that the N-terminal domains of BTS and BTS-LIKE2 (BTSL2) respectively bind three a...
Continue readingCarbon dioxide (CO2) generally exists as the main impurity in natural gas, whose main component is methane. The presence of CO2 reduces the energy content of natural gas and also causes the corrosion of pipelines. To prevent such problems, natural gas must contain a small concentration of CO2 (less than 2% by weight). Membrane technology is an attractive separati...
Continue readingAntibodies bind to antigens with hypervariable loops called complementarity-determining regions (CDRs). In contrast to conventional antibodies, a subset of bovine antibodies has an ultra-long CDR (ulCDR) composed of up to 70 residues folded as a stalk and knob. The fundamental principles of how these antibodies maintain their structure and stability remain enigma...
