Bidirectional Inhibiting Interfacial Ion Migration in the Inorganic Hole Transport Layer for Perovskite Light-Emitting Diodes.

CuZnSnS (CZTS) is strong candidate for hole transport in perovskite light emitting diodes (PeLEDs) due to their cost-effectiveness, deep highest occupied molecular orbital (HOMO), and high hole mobility. However, its inherent polymetallic ions usually deteriorate the quality of the perovskite emission layer (EML) affecting device performance. In this study, a bidirectional anchoring strategy is proposed by adding 15-crown-5 ether (15C5) into CZTS hole transport layer (HTL) to suppress the reaction between HTL and EML.

Efficacy and Safety of Phosphatidylinositol 3-kinase Inhibitors for Patients with Breast Cancer: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Background: Phosphatidylinositol 3-kinase (PI3K) inhibitors belong to the class of drugs that inhibit the activity of the PI3K protein, which is commonly overexpressed in breast cancer cells. However, there is a need to summarize the evidence to provide conclusive advice on the benefit of PI3K inhibitors in breast cancer patients. Therefore, this review assessed the effectiveness and safety of the PI3K inhibitors amongst breast cancer patients.

Plasma-assisted nitrogen doping in Ni-Co-P hollow nanocubes for efficient hydrogen evolution electrocatalysis.

To surmount the issues of a limited specific surface area and slow electrolyte diffusion in composite electrocatalysts, three-dimensional (3D) porous hollow nanocubes are fabricated, in which bimetal Ni-Co phosphide composites are covered with nanoparticles. The abundant hollow space provides more active sites for the catalyst, and simultaneously ensures efficient mass transfer and electron transport during the hydrogen evolution reaction (HER). A plasma-assisted approach is employed for smart N-doping in the Ni-Co phosphide hollow nanocubes (N-Ni-Co-P HNCs).

Sulfur doping enhanced desorption of intermediates on NiCoP for efficient alkaline hydrogen evolution.

Electrocatalysts with high catalytic activity, high stability and low cost are critical to the hydrogen evolution reaction (HER). In this paper, sulfur(S)-doped NiCoP nanowire arrays on a carbon fiber paper skeleton (S-NiCoP NW/CFP) are prepared, and it is demonstrated that the electrocatalytic properties of NiCoP in alkaline solution could be well improved by sulfur doping.
