Via incorporation of Sr2+ into (Pb,La)(Zr,Sn,Ti)O3, high recoverable energy density (Ure) is achieved in (Pb,Sr,La)(Zr,Sn,Ti)O3 (PSLZST) ceramics. All modified ceramics exhibit orthorhombic antiferroelectric (AFE) characteristics, and have higher ferroelectric-AFE phase switching electric field (EA, proportional to Ure) than the base composition with a tetragonal AFE phase. By properly adjusting content, Ure PSLZST greatly improved. This attributed substitution Pb2+ by smaller ion radius,...

(Pb,La)(Zr,Sn,Ti)O3 (PLZST) antiferroelectric (AFE) materials have been widely investigated for advanced pulsed power capacitors because of their fast charge-discharge rates and superior energy-storage capacity. For practical applications, require not only large energy density but also high efficiency, which are very difficult to achieve simultaneously. To address this problem, we herein investigate the properties PLZST AFE ceramics with a Sn content by considering that introduction can make...

In this work, we employed dendrimerlike mesoporous silica nanoparticles with hierarchical pores (HPSNs) to fabricate drug delivery system bioimaging and targeted tumor therapy in vivo. N,N-phenylenebis(salicylideneimine)dicarboxylic acid (Salphdc) was used both as the gatekeeper of HPSNs via pH-responsive coordination bonds between −COOH Salphdc In3+ ions a fluorescence imaging agent. Folic then conjugated targeting unit. The results revealed that could deliver model DOX site high efficiency...

AgNbO3 based antiferroelectric (AFE) ceramics have large maximum polarization and low remanent polarization, thus are important candidates for fabricating dielectric capacitors. However, their energy storage performances been still difference with those of lead-based AFEs because room-temperature ferrielectric (FIE) behavior. In this study, novel La3+ Ta5+ co-substituted designed developed. The introduction decreases the tolerance factor, reduces polarizability B-site cations increases local...

Sensitive and selective protein detection based on the aptamer-controlled noncovalent porphyrin probe self-assembly is reported for first time. Vascular endothelial growth factor (VEGF) a predominant biomarker in cancer angiogenesis. In this work, positively charged probe, manganese(III) meso-tetrakis(N-methylpyridinum-4-yl)porphyrin (Mn–PyP), was prepared. Using it as catalyst, label-free chemiluminescence (CL) turn-on approach sensitive VEGF developed. Mn–PyP could catalyze luminol CL...

Abstract Post-translational modifications (PTMs) are critical molecular mechanisms that regulate protein functions temporally and spatially in various organisms. Since most PTMs dynamically regulated, quantifying PTM events under different states is crucial for understanding biological processes diseases. With the rapid development of high-throughput proteomics technologies, massive quantitative proteome datasets have been generated. Thus, a comprehensive one-stop data resource surfing big...

Abstract High energy density ( W rec ) dielectrics with excellent efficiency η and thermal stability are crucial in high‐power storage applications. In this work, we introduce Ba(Zr 0.2 Ti 0.8 )O 3 (BZT) into Bi 0.5 Na TiO (BNT) to delay saturation polarization refine grain sizes for enhancing performance.

Genetic variants can affect protein function by driving aberrant subcellular localization. However, comprehensive analysis of how mutations promote tumor progression influencing nuclear localization is currently lacking. Here, we systematically characterize potential shuttling-attacking (SAMs) across cancers through developing the deep learning model pSAM for ab initio decoding sequence determinants nucleocytoplasmic shuttling. Leveraging cancer 11 types, find that SAMs enrich functional...
