Buried Interface Passivation with 3,4,5-Trifluorophenylboronic Acid Enables Efficient and Stable Inverted Perovskite Solar Cells.

The p-i-n type perovskite solar cells with a nickel oxide (NiOx) hole transport layer in combination with self-assembled monolayers (SAMs) have a high power conversion efficiency (PCE) of over 26%. The surface properties of the SAM layer have a significant impact on the growth and crystallization of the perovskite film. In the meanwhile, defects formed during thermal annealing at the SAM layer and the perovskite layer interface would act as charge recombination centers, decreasing device performance and stability.

Antibacterial effect of femtosecond laser against Enterococcus faecalis and Fusobacterium nucleatum biofilms on dentin: an in vitro study.

Background: Removing infectious bacteria biofilms from the root canal system is crucial for a successful endodontic treatment. This study investigated the antibacterial effect of femtosecond laser (fs-laser) against Enterococcus faecalis (E. faecalis) and Fusobacterium nucleatum (F.

Green synthesis of polysaccharide-based Ag@AgCl photoactive porous hydrogel spheres for enhanced visible light photocatalytic degradation of organic pollutants.

Improving the visible light activity and recyclability of photocatalysts remains a key challenge for organic pollutant degradation in wastewater. In this study, enteromorpha polysaccharide (EP) and xanthan gum (XG) were combined to preload Ag ions, with CO bubbles introduced via a pressure-decompression method. After cross-linking with ZrOCl via drip infusion, porous hydrogel spheres embedded with photoactive Ag@AgCl nanoparticles (NPs) were obtained.

Alginate-polyacrylamide double-network hydrogel sensors: Biomass-based piezoresistive platform with liquid metal and convex array for enhanced sensitivity.

The hydrogel sensors with outstanding tensile strength, high sensitivity, broad sensing range and excellent stability are highly desired for flexible electronics. Here, a double network piezoresistive flexible hydrogel sensor equipped with a convex structure was fabricated using the template method, which consists of CMCNTs-PAM/SA-Ca convex array and ultra-high-conductivity liquid metal droplets (LMs). Such a novel hybrid architecture enables the prepared piezoresistive sensor to have high sensitivity (GF up to 32.

Hexavalent chromium induces ferroptosis in small intestinal tissue of broilers through GPX4/HMGB1/p38-MAPK pathway.

As a major environmental heavy metal pollutant, hexavalent chromium (Cr(VI)) causes irreversible damage to animals and humans. Nevertheless, how Cr(VI) exposure causes intestinal damage in broilers remains inadequately explored. This study explores Cr(VI)-induced poisoning using potassium dichromate to build a Cr(VI) poisoning model.
