A Structurally Simple Polymer Donor Enables High-Efficiency Organic Solar Cells with Minimal Energy Losses.
Angew Chem Int Ed Engl

Energy loss (Eloss) between optical energy gap (Eg) and open-circuit voltage (eVoc) sets efficiency upper limits for organic solar cells (OSCs). Nevertheless, further breaking the limit of Eloss in OSCs is challenging, especially via structurally simple materials in binary OSCs. Herein, a structurally simple non-halogenated polymer donor, namely PBDCT, is developed for realizing high-efficiency OSCs with record-breaking Eloss.

Clarifying the stability and co-transport of environmental colloids and radionuclides in porous media is crucial, as they pose potential risks to nuclear environmental safety. However, there is limited knowledge of the significant role of protein corona in Eu(III) transport carried by bentonite colloids (BC) in the presence of bovine serum albumin (BSA). The protein corona mediated the stability and co-transport behaviors of BC and Eu(III) in saturated quartz columns were investigated, and a ripening adsorption co-transport model (RACM) was established to qualitatively describe the Eu(III) transport by composited colloids.

Varicellovirus bovinealpha (BoAHV) types 1(BoAHV-1) is one of the most significant viruses affecting cattle, causing substantial economic losses in the global cattle industry. Virus productive infection in cell cultures leads to mitochondrial dysfunction, resulting in the overproduction of reactive oxygen species (ROS), which act as inflammatory mediators and exert cytotoxic effects. But the underlying mechanisms remain poorly understood.

The tetracycline resistance gene tetA is a widely detected antibiotic resistance gene (ARG) posing significant ecological health risks in surface water. The development of rapid quantitative assays for tetA can substantially reduce both the time and economic costs associated with real-time monitoring of tetA transportation dynamics in the environment. In this study, a novel method for the quantification of tetracycline resistance gene tetA using real-time recombinase polymerase amplification was developed, which can complete the quantification of tetA within 20 minutes at a constant temperature of 39 ℃, achieving a detection limit of 50 copies/μL with 100 % sensitivity and specificity.
