Low‐Ru‐Content CuCoRu Aerogel for Boosted Electrocatalytic Nitrate Reduction to Ammonia

open access: yesEcoEnergy, EarlyView.
Low‐Ru‐content Cu5Co5Ru aerogel with enhanced hydrogenation ability and 3D robust aerogel skeletons enables high‐efficiency and long‐term electrocatalytic nitrate reduction to ammonia at low overpotential, achieving an exceptional ammonia yield rate of 2.7 ± 0.1 mmol cm−2 h−1 and a high Faradaic efficiency of ∼97% at −0.1 V versus RHE as well as an ...

Correlated Ground-based and IUE Observations [PDF]

open access: yes
The value of coordination among different observers particularly, those working in different wavelength regions is highlighted. This coordination is more important among observers of comets than among observers of almost any other class of astronomical ...

Simple (YGa)2O3/F‐SnO2 Heterojunction‐Based Solar‐Blind Ultraviolet Photodetector Operable in Two Modes With Superb Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Yttrium doping was proposed to expand the bandgap and inhibit the oxygen vacancies of Ga2O3 to form (YGa)2O3 alloy with reduced background carriers and trap centers. Beneficially, simple vertical‐structured (YGa)2O3/FTO heterojunction photodetectors exhibit superb performance with particularly low dark current and fast photoresponse in both self‐driven

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

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
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 ...

Visible Photosensitizing Disinfectant Spray for Combating Multidrug‐Resistant Candidozyma Auris in Healthcare Settings

open access: yesExploration, EarlyView.
We designed and synthesized a dual‐type AIE photosensitizer (named TB) spray, containing a cationic quaternary ammonium unit and a glycosyl‐targeted boronic acid moiety, characterized for the elimination of biofilm infections of Candidozyma auris (C. auris) on high‐touch surfaces.
