Constructing Cu/Cu2O Heterogeneous Interface for Efficient Urea Electrosynthesis
In this study, a Cu/Cu2O heterogeneous interface with dual active sites is prepared for electrocatalytic CO2 and NO3− coupling to urea. The catalyst shows high yield rates of 1156.63 mmol g−1 h−1 and FE of 29.67% at −1.0 V (vs RHE), which is significantly higher than Cu and Cu2O, highlighting the advantages of heterogeneous interface synergistic ...

Photoelectron transfer mechanism and photocatalytic O2‐to‐H2O2 reduction process over hollow HS@CuFe@CuS heterojunction photocatalysts. Recently, photocatalytic synthesis of H2O2 has received much attention. However, the photocatalytic activity of photocatalysts is generally limited due to multiple factors, such as insufficiency of photoelectrons, low ...

Antibacterial Activity of Heteropolytungstates Against Proteus mirabilis
We investigated the in vitro antibacterial activity of several heteropolytungstates against P. mirabilis, a drug‐resistant pathogen. All tested polyanions inhibited bacterial growth, with the Preyssler–Pope–Jeannin polyanion P5W30 exhibiting the highest activity (MIC = 0.78 mg/mL).

A methoxy‐functionalized pyrene‐based covalent organic framework (Py‐OCH3‐COF) enables efficient photoelectrocatalytic (PEC) degradation of tetracycline (TC) under neutral conditions. PEC synergy promotes charge separation, reshapes reactive oxygen species, and generates singlet oxygen as the dominant species, leading to rapid and effective TC ...

Assessing variability of literature based methane indicator traits in a large dairy cow population
Description of the subject. Dairy production is identified as a major source of methane (CH4) emissions. Selective breeding represents one method for mitigating CH4 emissions but practical and cheap ways to measure this trait are not currently available.

Wantz et al. reveal how donor–acceptor interactions govern light‐induced degradation in organic solar cells. PTQ10 is destabilized, whereas PM6 is partially stabilized by Y6‐12. Crystallinity suppresses photo‐oxidation while modulating performance, defining key design principles for efficient, long‐lived organic photovoltaics.

A hydrogel with dynamic cross‐links was formed by cross‐linking hyaluronic acid with curcumin‐preloaded, phenylboronic acid‐modified poly(amidoamine) dendrimers. This hydrogel exhibited excellent injectability and self‐healing ability, enabling controlled Cur release in response to low pH, high reactive oxygen species (ROS) generation, or mechanical ...

Polarized IR spectrophotometry of acenaphthene
Polarized infrared spectrophotometry of acenaphthene and acenaphthene-d10 in stretched polyethylene sheets was used to assign symmetry to vibrational normal modes. B3LYP/6-31G(d) DFT calculations were employed to assist in assignments.
