Stimuli-responsive shape-transforming hydrogels have shown great potential toward various engineering applications including soft robotics and microfluidics. Despite significant progress in designing with ever more sophisticated shape-morphing behaviors, an ultimate goal yet to be fulfilled is programmable reversible shape transformation. It reported here that transient structural anisotropy can programmed into copolymer of N-isopropylacrylamide stearyl acrylate. Structural arises from the...
Far-from-equilibrium (FFE) conditions give rise to many unusual phenomena in nature. In contrast, synthetic shape-shifting materials typically rely on monotonic evolution between equilibrium states, limiting inherently the richness of behaviors. Here we report an unanticipated behavior for a hydrogel that can be programmed operate FFE-like behavior. During its temperature triggered event, stress induces uneven water diffusion, which pushes off based natural pathway. The resulting geometric...
Abstract Salmonella enterica serovar Typhimurium ( S . Typhimurium) is a major cause of salmonellosis, and the emergence multidrug-resistant pathovariants has become growing concern. Here, we investigate distinct rough colony variant exhibiting strong biofilm-forming ability isolated in China. Whole-genome sequencing on 2,212 Chinese isolates 1,739 publicly available genomes reveals population structure evolutionary history variants. Characterized by macro, red, dry, (mrdar) colonies, these...
Stress-free two-way shape memory polymers (2W-SMPs) capable of reversible shifting between two distinct shapes are versatile platforms for the development future smart devices. However, it is challenging to prepare stress-free 2W-SMPs with good actuation performance and programmability from single-component semicrystalline polymers. Herein, we demonstrate a straightforward universal strategy preparing through self-nucleated crystallization (SNC) SNC enables formation types crystals in...
Rapid and accurate identification of tree species via remote sensing technology has become one the important means for forest inventory. This paper is to develop an framework that integrates unmanned airborne vehicle (UAV)-based hyperspectral image light detection ranging (LiDAR) data under complex condition natural coniferous broad-leaved mixed forests. First, UAV-based LiDAR were obtained from a in Maoer Mountain area Northeast China. The preprocessed was segmented using distance-based...
Abstract A hexagonal boron nitride (hBN) based p‐n homo‐junction is expected to demonstrate a great potential for being fabricated into an emitter (either light‐emitting diode or laser diode) in the deep‐UV spectral region. However, it remains challenge achieve n‐type conductive hBN. Herein, hBN obtained by means of doping sulfur The structure and electric properties S‐doped studied via density functional theory, indicating that orbital coupling between S 3p B 2p introduces shallow donor...
A simple two-step approach was proposed to obtain hBN thin films with high crystalline quality, meaning that the were initially prepared by using an RF magnetron sputtering technique and subsequently followed a post-annealing process at temperature. In case of introducing Al2O3 nanoparticles, effects annealing temperature from 1000 °C 1300 time 0.5 h 1.5 on recrystallization grown systematically studied XRD SEM technologies. The introduction impurities during successfully reduced transition...
The BMP/Smad signaling pathway plays an important role in the viability and differentiation of osteoblast; however, it is not clear whether this involved fluoride-induced osteoblast differentiation. In study, we investigated osteoblast-like Saos-2 cells Cells were exposed to fluoride different concentrations (0, 0.1, 0.2, 0.4, 0.8, 1.6 mM), cell proliferation was determined using WST assays. expression marker genes such as osteocalcin (BGP) bone alkaline phosphatase (BALP) detected by...
Abstract Antimicrobial resistance of Shigella sonnei has become a global concern. Here, we report phylogenetic group S. with extensive drug resistance, including combination multidrug coresistance to ceftriaxone and azithromycin (cef R azi ), reduced susceptibility fluoroquinolones, even colistin (col ). This distinct clone caused six waterborne shigellosis outbreaks in China from 2015 2020. We collect 155 outbreak isolates 152 sporadic isolates. The cef isolates, strains, are mainly...
Objective: To investigate the effects of ginsenoside metabolite compound K (CK) on adjuvant-induced arthritis (AA) rats and partial mechanisms focused function immunocyte (B cell macrophage) effectors’ (fibroblast-like synoviocyte, FLS).Methods: Animals were divided randomly into nine groups including control, AA, CK (5, 10, 20, 40, 80, 160 mg/kg, i.g.), MTX (0.5 i.g.). The AA are evaluated by swelling paw, histopathology joint, inflammatory cytokine production in serum. further B cell,...
Switching temperature (Tsw) is a key parameter governing the service condition of shape memory polymers (SMPs). However, tuning Tsw SMPs often requires sophisticated synthesis or intricate processing. Herein, we report simple yet effective strategy to prepare with tunable and good reconfigurability by using cocrystalline polyesters as reversible phase. The cocrystallizable copolyesters rearranged sequences were prepared transesterification mixed polyester diols then photo-cross-linked...
