Flexible ferroelectrics High-quality ferroelectric materials, which polarize in response to an electric field, are usually oxides that crack when bent. Dong et al. found high-quality membranes of barium titanate surprisingly flexible and super-elastic. These films accommodate large strains through dynamic evolution nanodomains during deformation. This discovery is important for developing more robust devices. Science , this issue p. 475
Recently, microRNA (miRNA)‐mediated RNA interference has been developed as a useful tool in gene function analysis and therapy. A major obstacle miRNA‐mediated RNAi is cellular delivery, which requires an efficient flexible delivery system. The self‐assembly of the MS2 bacteriophage capsids used to develop virus‐like particles (VLPs) for drug delivery. However, VLP‐mediated miRNA not yet reported. We therefore Escherichia coli expression system produce pre‐miR 146a contained VLPs, then...
Abstract Elasticity is a fundamental mechanical property of two-dimensional (2D) materials, and critical for their application as well strain engineering. However, accurate measurement the elastic modulus 2D materials remains challenge, conventional suspension method suffers from number drawbacks. In this work, we demonstrate to map in-plane Young’s mono- bi-layer MoS 2 on substrate with high spatial resolution. Bimodal atomic force microscopy used accurately effective spring constant...
Increasing evidence suggests that dysregulated immune responses are associated with the clinical outcome of coronavirus disease 2019 (COVID-19). Nucleocapsid protein (NP)-, spike (S)-, receptor binding domain (RBD)- specific immunoglobulin (Ig) isotypes, IgG subclasses and neutralizing antibody (NAb) were analyzed in 123 serum from 63 hospitalized patients severe, moderate, mild or asymptomatic COVID-19. Mild to modest correlations found between severity antigen serum, which IgG1 IgG3...
Altered miRNA expression is believed to play a crucial role in variety of human cancers; however, the mechanisms leading dysregulation remain elusive. In this study, we report that Y box-binding protein (YB-1), major mRNA packaging protein, novel modulator processing glioblastoma multiforme (GBM). Using individual nucleotide-resolution crosslinking immunoprecipitation coupled deep sequencing (iCLIP-seq), performed first genome-wide analysis vivo YB-1-RNA interactions and found YB-1...
Abstract Flexible ferroelectric field effect transistors (FeFETs) with multiple functionalities and tunable properties are attractive for low power sensing, nonvolatile data storage, as well emerging memristor applications such artificial synapses, though the state‐of‐art flexible FeFETs based on organic materials possess polarization, large coercivity, high operating voltage, suffer from poor thermal stability. Here, developed is an all‐inorganic FeFET epitaxial Pb(Zr 0.1 Ti 0.9 )O 3 /ZnO...
Abstract Primary liver cancer is the third leading cause of death in world, and lack effective treatments main reason for high mortality. Corosolic acid (CA) has been proved to have antitumor activity. In this study, we found that CA can sensitize cells ferroptosis, which a regulated form cell characterized by iron-dependent lipid peroxides reaching lethal levels. Here, revealed inhibit glutathione (GSH) synthesis via HERPUD1, decreasing cellular GSH level causing become more sensitive...
Near infrared (NIR) quantum cutting involving the conversion of an absorbed blue photon into two NIR photons emission has been realized in heavy Yb doped Ce0.03Yb3xY(2.97−3x)Al5O12 (x=0.1, 0.25, and 0.5) transparent ceramics. Upon 467 nm excitation, energy transfer process was dominated by cooperative downconversion from 5d1 state one Ce3+ ion to F25/2 Yb3+ ions. The influence Ce4+–Yb2+ charge (CTS) should not contribute much for large gap between Ce3+:5d1 CTS. calculated yield x=0.25 sample...

Piezoresponse force microscopy (PFM) is a powerful tool widely used to characterize piezoelectricity and ferroelectricity at the nanoscale. However, it necessary distinguish microscopic mechanisms between non-piezoelectric contributions measured by PFM. In this work, we systematically investigate first second harmonic apparent piezoresponses of silicon wafer in both vertical lateral modes, show that exhibits an electromechanical response quadratic applied electric field, possibly arising...
Multiferroics are a time-honoured research subject by reason for their tremendous application potential in the information industry, such as multi-state storage devices and new types of sensors. An outburst studies on multiferroicity has been witnessed 21st century, although this field long history since 19th century. Multiferroicity now become one hottest topics condensed matter physics materials science. Numerous efforts have made to investigate cross-coupling phenomena among ferroic...

Multiferroics have received intense attention due to their great application potential in multi-state information storage devices and new types of sensors. Coupling among ferroic orders such as ferroelectricity, (anti-)ferromagnetism, ferroelasticity so on will enable dynamic interaction between these ordering parameters. Direct visualization coupling behavior single-phase multiferroic materials is highly desirable for both applications fundamental study. Manipulation ferroelectric magnetic...
