Constructing Cu/Cu2O Heterogeneous Interface for Efficient Urea Electrosynthesis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
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 ...

Boosting Photocatalytic H2O2 Synthesis Over HKUST‐1 MOFs‐Derived Hollow HKUST‐1@CuFePBA@CuS Heterojunctions

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
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

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 18, 22 June 2026.
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).

Photoelectrocatalytic Degradation of Tetracycline Using Covalent Organic Frameworks Under Neutral Conditions

open access: yesChemElectroChem, Volume 13, Issue 12, 17 June 2026.
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

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2015
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.

On the Photo‐Oxidation of Organic Photovoltaic Materials: The Case of PTQ10 and PM6 Blends With Y6‐12

open access: yesSolar RRL, Volume 10, Issue 11, 15 June 2026.
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.

Multi‐Responsive Dendrimer‐Hyaluronic Acid Hydrogel With Lubricating and Immunoregulatory Functions for Synergistic Osteoarthritis Therapy

open access: yesAdvanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
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

open access: yes, 2000
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.
