The power conversion efficiency (PCE) of CH3NH3PbX3 (X = I, Br, Cl) perovskite solar cells has been developed rapidly from 6.5 to 18% within 3 years. However, the anomalous hysteresis found in I-V measurements can cause an inaccurate estimation efficiency. We attribute phenomena ferroelectric effect and build a model based on diode explain it. CH3NH3PbI3-xClx is strongly suggested by characterization methods E-P (electrical field-polarization) loop. curves greatly depend scan range as well...
The outbreak of Coronavirus Disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in Wuhan, December 2019, and continuously poses a serious threat to public health. Our previous study has shown that cytokine storm occurred during SARS-CoV-2 infection, while detailed role cytokines disease severity progression remained unclear due limited case number. In this study, we examined 48 plasma samples from 53 COVID-19 cases, among whom 34 were...
Intrinsic polarization of ferroelectrics (FE) helps separate photon-generated charge carriers thus enhances photovoltaic effects. However, traditional FE with transition-metal cations (M) d0 electron in MO6 network typically has a band gap (Eg) exceeding 3.0 eV. Although smaller Eg (2.6 eV) can be obtained multiferroic BiFeO3, the value is still too high for optimal solar energy applications. Computational "materials genome" searches have predicted several exotic < 2.0 eV, all far...

One great challenge for supercapacitor is to achieve high energy capacity and fast charge/discharge rates simultaneously. Porous graphene with large surface area a promising candidate electrode materials of supercapacitor. Using first-principles calculations non-equilibrium Green's function technique, we have explored the formation energies, mechanical properties, diffusion behaviors electrical conductance sheets various hole defects and/or nitrogen doping. Interestingly, pyridinic-like...
α-amino acids bearing aromatic side chains are important synthetic units in the synthesis of peptides and natural products. Although various β-C-H arylation methodologies for amino acid derivatives involving assistance directing groups have been extensively developed, syntheses that directly employ N-protected as starting materials remain rare. Herein, we report an N-acetylglycine-enabled Pd-catalysed carboxylate-directed β-C(sp3)-H aliphatic acids. In this way, non-natural can be prepared...
A Ru-catalyzed 1,1′-binaphthyl-2,2′-diylhydrogen phosphate (BNDHP)-enabled meta C–H benzylation under the assistance of ferrocene using less sterically hindered toluene derivatives as coupling partners has been developed. Various arenes bearing pyridyl, pyridmidyl, and pyrazolyl directing groups can be selectively coupled with toluenes at positions in moderate to good yield. mechanistic study clearly showed site selectivity ortho or position is completely controlled by ligand BNDHP catalyst...
Exploring the origin of transition metal (TM) lattice-doped layered double hydroxides (LDHs) toward oxygen evolution reaction (OER) plays a crucial role in engineering efficient electrocatalysts.

T-cell immune responses modulated by immunoglobulin and mucin domain-containing molecule 3 (Tim-3) during Mycobacterium tuberculosis (Mtb) infection in humans remain poorly understood. Here, we found that active TB patients exhibited increases numbers of Tim-3-expressing CD4+ CD8+ T cells, which preferentially displayed polarized effector memory phenotypes. Consistent with phenotypes, Tim-3+CD4+ Tim-3+CD8+ subsets showed greater functions for producing Th1/Th22 cytokines CTL molecules than...
