Abstract
Recent advances in passive flying systems inspired by wind-dispersed seeds contribute to increasing interest in their use for remote sensing applications across large spatial domains in the Lagrangian frame of reference. These concepts create possibilities for developing and studying structures with performance characteristics and operating mechanisms that lie beyond those found in nature. Here, we demonstrate a hybrid flier system, fabricated through a process of controlled buckling, to yield unusual geometries optimized for flight. Specifically, these constructs simultaneously exploit distinct fluid phenomena, including separated vortex rings from features that resemble those of dandelion seeds and the leading-edge vortices derived from behaviors of maple seeds. Advanced experimental measurements and computational simulations of the aerodynamics and induced flow physics of these hybrid fliers establish a concise, scalable analytical framework for understanding their flight mechanisms. Demonstrations with functional payloads in various forms, including bioresorbable, colorimetric, gas-sensing, and light-emitting platforms, illustrate examples with diverse capabilities in sensing and tracking.

Abstract
The storage and transfer of energy require a safe technology to mitigate the global environmental issues resulting from the massive application of fossil fuels. Fuel cells have used hydrogen as a clean and efficient energy source. Nevertheless, the storage and transport of hydrogen have presented longstanding problems. Recently, liquid organic hydrogen carriers (LOHCs) have emerged as a solution to these issues. The hydrogen storage technique in LOHCs is more attractive than those of conventional energy storage systems like liquefaction, compression at high pressure, and methods of adsorption and absorption. The release and acceptance of hydrogen should be reversible by LOHC molecules following favourable reaction kinetics. LOHCs comprise liquid and semi-liquid organic compounds that are hydrogenated to store hydrogen. These hydrogenated molecules are stored and transported and finally dehydrogenated to release the required hydrogen for supplying energy. Hydrogenation and dehydrogenation are conducted catalytically for multiple cycles. This review elaborates on the characteristics of different LOHC molecules, based on their efficacy as energy generators. Additionally, different catalysts used for both hydrogenation and dehydrogenation are discussed.

Abstract
Beyond storage and transmission of genetic information in cellular life, nucleic acids can perform diverse interesting functions, including specific target recognition and biochemical reaction acceleration; the versatile biopolymers, however, are acutely vulnerable to hydrolysis-driven degradation. Here, we demonstrate that the cage effect of choline dihydrogen phosphate permits active folding of nucleic acids like water, but prevents their phosphodiester hydrolysis unlike water. The choline-based ionic liquid not only serves as a universal inhibitor of nucleases, exceptionally extending half-lives of nucleic acids up to 6 500 000 times, but highly useful tasks of nucleic acids (e.g. mRNA detection of molecular beacons, ligand recognition of aptamers, and transesterification reaction of ribozymes) can be also conducted with well-conserved affinities and specificities. As liberated from the function loss and degradation risk, the presence of undesired and unknown nucleases does not undermine desired molecular functions of nucleic acids without hydrolysis artifacts even in nuclease cocktails and human saliva.

Abstract
A bacterial strain, designated as S8T, was isolated from the gut contents of Seriola quinqueradiata from the coastal sea area of Jeju Island, South Korea. The strain is a Gram-staining positive, non-motile, non-spore-forming, facultative anaerobic coccus. Optimal growth was observed at 30 °C, pH 8.0-9.0, and 0-0.5% w/v NaCl, under anaerobic conditions. The predominant fatty acids were C18:1 ω9c, C16:0, C18:0, and C16:1 ω9c, while quinone was not detected. The genome was 2,224,566 bp long, with a GC content of 38.2%. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain S8T had 96.2% similarity with Granulicatella adiacens ATCC 49175T, its closest known species according to nomenclature. The DNA-DNA hybridization (dDDH), average nucleotide identity, and average amino acid identity values between strain S8T and G. adiacens ATCC 49175T were 25.7%, 85.5%, and 77.2%, respectively, all of which fall below the recommended threshold for species differentiation. Based on genomic, phenotypic, and phylogenetic evidence, we propose that strain S8T should be a novel species within the genus Granulicatella, for with the name Granulicatella seriolae sp. nov. is proposed. The type strain is S8T (KCTC 43438T = JCM 35604T).

Abstract
We investigated the effects of crude protein (CP) levels and exogenous enzymes on growth performance, meat quality, toxic gas emissions, and colonic microbiota community in 200 finishing pigs. Four groups corresponded to 4 diets: 16.74% CP (high-protein level, HP) and 14.73% CP (medium protein level, MP) diet supplemented with or without 1-g/kg multi-enzymes (ENZs, including 1000-U/kg protease, 2500-U/kg α-amylase, and 10,000-U/kg β-glucanase), using a 2 × 2 factorial arrangement. After 7 weeks of trial, ENZs supplementation increased (P < 0.05) the average daily gain (ADG) of finishing pigs during weeks 4 to 7 and in the overall period and improved gross energy utilization. Dietary HP improved (P < 0.05) ADG during the overall period. The MP diet-treated pigs had higher intramuscular fat (IMF) content in the longissimus dorsi muscle (P < 0.01). ENZs supplementation to the MP diets lowered muscle IMF content (P < 0.01). Additionally, pigs fed the HP diet released (P < 0.05) more NH3 and H2S in excrement. The HP diet enhanced (P < 0.05) intestinal microbial richness, represented by higher observed_ amplicon sequence variants and Chao1. Administration of ENZs to the HP diet increased (P < 0.05) the Shannon and Pielou's evenness. Dietary MP promoted Firmicutes proliferation. Supplementary HP diet increased the relative abundances of Spirochaetota, Verrucomicrobiota, Desulfobacterota, and Fibrobacterota (P < 0.05). Supplemental ENZ elevated (P < 0.05) Actinobacteriota and Desulfobacterota abundances. ENZ supplementation to the HP diet increased the abundances of Bacteroidota, Desulfobacterota, and Proteobacteria but lowered their abundances in the MP diet. Taken together, the HP diet or ENZs' supplements improved growth performance. Although the interaction between CP levels and ENZs had no effect on growth performance, it modulated colonic flora and muscle IMF content.

Abstract
Van der Waals (vdW) heterostructures composed of atomically thin two-dimensional (2D) materials have more potential than conventional metal-oxide semiconductors because of their tunable bandgaps, and sensitivities. The remarkable features of these amazing vdW heterostructures are leading to multi-functional logic devices, atomically thin photodetectors, and negative differential resistance (NDR) Esaki diodes. Here, an atomically thin vdW stacking composed of p-type black arsenic (b-As) and n-type tin disulfide (n-SnS2 ) to build a type-III (broken gap) heterojunction is introduced, leading to a negative differential resistance device. Charge transport through the NDR device is investigated under electrostatic gating to achieve a high peak-to-valley current ratio (PVCR), which improved from 2.8 to 4.6 when the temperature is lowered from 300 to 100 K. At various applied-biasing voltages, all conceivable tunneling mechanisms that regulate charge transport are elucidated. Furthermore, the real-time response of the NDR device is investigated at various streptavidin concentrations down to 1 pm, operating at a low biasing voltage. Such applications of NDR devices may lead to the development of cutting-edge electrical devices operating at low power that may be employed as biosensors to detect a variety of target DNA (e.g., ct-DNA) and protein (e.g., the spike protein associated with COVID-19).
