Electromechanical (EM) coupling-the conversion of energy between electric and mechanical forms-in ferroelectrics has been used for a broad range applications. Ferroelectric polymers have weak EM coupling that severely limits their usefulness We introduced small amount fluorinated alkyne (FA) monomers (<2 mol %) in relaxor ferroelectric poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) (PVDF-TrFE-CFE) terpolymer markedly enhances the polarization change with strong while...
Protein post-translational modifications (PTMs) participate in important bioactive regulatory processes and therefore can help elucidate the pathogenesis of non-alcoholic fatty liver disease (NAFLD). Here, we investigate involvement PTMs ketogenic diet (KD)-improved by multi-omics reveal a core target lysine malonylation, acetyl-coenzyme A (CoA) carboxylase 1 (ACC1). ACC1 protein levels Lys1523 malonylation are significantly decreased KD. malonylation-mimic mutant increases its enzyme...
The rational construction of highly active and stable non-noble metal electrocatalysts for the oxygen reduction reaction (ORR) is an ongoing challenge practical applications catalysts. Here, we report a novel nanostructured hollow N-doped carbon hybrid through pyrolysis silica@CoZn-coordinated zeolitic imidazolate frameworks. layer encased cobalt nanoparticles were embedded in hierarchically porous catalyst (Co@C-HN-hC). Profiting from synergistic effect between Co@C NPs HN-hC, Co@C-HN-hC...
Polymers that generate large shape changes under electric stimulation are of great interest for many applications. Recently, it was shown converting a small amount chlorofluoroethylene (CFE) in relaxor ferroelectric poly(vinylidene fluoride–trifluoroethylene–CFE) (PVDF-TrFE-CFE) terpolymer into fluorinated alkyne (FA) creates P(VDF-TrFE-CFE-FA) tetrapolymers with giant electromechanical (EM) response at ultralow fields (<50 MV/m). We investigate the microscopic origin this effect and show...
Abstract Reactive oxygen species (ROS)‐based therapeutic strategies play an important role in cancer treatment. However, situ, real‐time and quantitative analysis of intracellular ROS treatment for drug screening is still a challenge. Herein we report one selective hydrogen peroxide (H 2 O ) electrochemical nanosensor, which prepared by electrodeposition Prussian blue (PB) polyethylenedioxythiophene (PEDOT) onto carbon fiber nanoelectrode. With the find that level H increases with NADH...
The origin of dielectric constant enhancement in high-temperature (high glass transition temperature Tg) polymer dilute nanocomposites is investigated via Infrared (IR) Spectroscopy applied through Atomic Force Microscope (AFM) and density functional theory (DFT) calculations. can be greatly enhanced by trace nanofiller loadings (&lt;0.5 vol. %) a broad class polymers without affecting or even with positive influence on breakdown strength loss. This avenue provides attractive systems for...
The incorporation of comonomers as structural defects has been extensively exploited to modulate the structures and physical properties poly(vinylidene fluoride) (PVDF)-based ferroelectric polymers. Previous studies have shown that large-sized can induce relaxor ferroelectricity in PVDF-based terpolymers a result stabilization helical conformation. Here, we show that, with incorporating small-sized defect, vinyl fluoride (VF), into copolymer, resulting preferentially adopt polar all-trans...
Abstract Paper‐based analytical devices, which are suited to point‐of‐care diagnostics and on‐site detection because of cheap price portability, have attracted increasing attention for improving global health in other applications. Here, we constructed one carbon nanotube paper‐based electrode (CNTPE) the neurochemicals brain microdialysate. CNTPE was directly fabricated through filter depositing CNT dispersion onto surface paper. The good electrochemical performance with advantage CNT, not...
The precise atomic structure of a metal contact significantly affects the performance nanoscale electronic devices. We use an accurate, DFT-based non-equilibrium Green’s function method to evaluate various contacts with graphene or nanoribbons. For surface not chemically bound graphene, Ti have lower resistance than those Au, Ca, Ir, Pt, and Sr. However, as edge contact, has larger Au. Bridging O atoms at Au lowers transmission by over 30%.

The transmembrane protein, TMEM200A, is known to be associated with human cancers and immune infiltration. Here, we assessed the function of TMEM200A in common by multiomics analysis used vitro cell cultures gastric cells verify results. expression several cancer types was using RNA-seq data from UCSC Xena database. Bioinformatic revealed a potential role as diagnostic prognostic biomarker. Cultures normal lines were grown knocked down. levels measured quantitative real-time polymerase chain...
