Energy‐storage properties of 0.89 Bi 0.5 Na TiO 3 –0.06 BaTiO –0.05 K NbO (0.89 BNT BT KNN ) lead‐free ceramics were first investigated. Measurements dielectric together with switching current curves indicate a rather diffuse ferroelectric ( FE to anti‐ferroelectric AFE phase transition when heating from 20°C 90°C. The energy density W ), which was calculated P–E hysteresis loops, increases linearly the external electric field E exceeds ‐ field. is independent temperature and frequency,...
Charge–discharge properties of an La‐modified Pb(Zr,Sn,Ti)O 3 (PLZST) antiferroelectric (AFE) ceramics capacitor were investigated by directly measuring its hysteresis loops and pulse discharge current–time curves under different electric fields. Large increments in polarization current observed when the field increases from to 3.5 kV/mm. Under 4 kV/mm, first peak this AFE (static capacitance around 4.4 nF) can surpass 1.1 kA, more than 80% charge stored be released <65 ns. Moreover,...
The charge-discharge properties of lanthanum- and niobium-doped lead zirconate stannate titanate ceramics were investigated by directly measuring the hysteresis loops, dielectric constants under a dc bias field, pulse discharge current-time curves after varying circulations. It was found that there no significant effect circulation on these properties. first current peak reached 1.8 kA at 40 kV/cm, most stored charge released in 500 ns. These results show obtained slanted with high energy...
The evolution of dynamic hysteresis lead zirconate titanate stannate antiferroelectric bulk ceramics at various frequencies ( f ) and field amplitudes E 0 has been investigated systematically. A series asymmetrical minor loops were observed when the working fields slightly lower than forward switching AF . As increased above , symmetrical double appeared their energy densities w against found to be fit scaling behavior as − 0.02 c 0.08 where representing threshold is designated study helpful...
Vanadium nitride and graphene have been widely used as pseudo-capacitive electric double-layer capacitor electrode materials for electrochemical capacitors, respectively. However, the poor cycling stability of vanadium low capacitance impeded their practical applications. Herein, we demonstrated an in situ self-sacrificed template method synthesis nitride/nitrogen-doped (VN/NGr) nanocomposites by pyrolysis a mixture dicyandiamide, glucose, NH4VO3. nanoparticles size range 2 to 7 nm were...
The exosome functions in the degradation of diverse RNA species, yet how it is negatively regulated remains largely unknown. Here, we show that NRDE2 forms a 1:1 complex with MTR4, nuclear cofactor critical for recruitment, via conserved MTR4-interacting domain (MID). Unexpectedly, mainly localizes speckles, where inhibits MTR4 recruitment and degradation, thereby ensures efficient mRNA export. Structural biochemical data revealed interacts MTR4's key residues, locks closed conformation,...
Titanium oxide (TiO2) semiconducting materials attracted great interest in photocatalytic degradation of organic pollutants the treatment textile wastewater recent days. The present study focuses on a sol-gel method for synthesizing nano-Fe doped TiO2 photocatalyst, and employs advanced oxidation technique termed activation persulfate to degrade azo dye. performance targeted degradant acid orange dye (AO7) was analyzed regarding impacts PDS concentration, solution pH, catalyst dose. Results...
ABSTRACT The corrosion behaviors of austenitic stainless steels 304 and 316 were systematically examined in a 60 wt. % NaOH solution at 240°C under an oxygen partial pressure 3.2 MPa. After 168h immersion corrosion, the steady rates 304SS 316SS determined as 6.60 mm/y 4.28 mm/y, respectively, with showing higher these conditions. Corrosion tests conducted different durations helped to reveal migration transformation patterns key elements steel this aggressive environment. mechanism was...
Phase transition and pyroelectric behaviors of Pb0.955La0.03(Zr0.42Sn0.40Ti0.18)O3 (PLZST) ceramics were investigated as functions temperature electric field. Pyroelectric coefficient about 160×10−8 C cm−2 K−1 is detected at the electric-field-induce ferroelectric (FEIN) to antiferroelectric phase for poled samples. Reversible response with a maximum 50×10−8 obtained when dc bias applied on depoled sample simultaneously.
Autoimmune Th1 and Th17 responses are critical for the development of central nervous system (CNS) pathology in experimental autoimmune encephalomyelitis (EAE), an animal model human multiple sclerosis. Although macrophages play important roles responses, whether modulating macrophage gene transcription can diminish Th1- cell-induced CNS is unclear. In this study, we successfully silenced expression factor c-Rel mice with EAE (including those infiltrating CNS) using chemically modified...
