Anomalous anisotropic exciton temperature dependence in rutile TiO2 [PDF]
Elucidating the details of electron-phonon coupling in semiconductors and insulators is a topic of pivotal interest, as it governs the transport mechanisms and is responsible for various phenomena such as spectral-weight transfers to phonon sidebands and

Study on the Reaction Mechanism of RuOx and Its Enhanced Hydrogen Evolution Reaction Activity
Advanced Science, EarlyView.In situ Raman spectroscopy and DFT calculations reveal that, prior to the onset of HER, the surface of RuOx undergoes reversible reduction and structural reconstruction. The resulting Ru(II)O/Ru(IV)O2 configuration is identified as the true catalytically active species.

Thermally Assisted Photocatalytic Dehydrogenation of Methanol in Continuous Steady‐State Operation
Advanced Science, EarlyView.Thermally assisted photocatalytic methanol dehydrogenation on Pt/TiO2 enables formaldehyde and hydrogen production far beyond thermodynamic limits. Continuous operation delivers up to 95% selectivity over 70 h, and oxygen microdosing strongly boosts conversion by regenerating surface oxygen sites.

Angewandte Chemie, EarlyView.Poly(lauryl methacrylate)‐poly(2‐hydroxyethyl methacrylate) (PLMA‐PHEMA) diblock copolymer nanoparticles prepared in non‐polar media serve as nanoreactors for the in situ synthesis of silica from tetraethyl orthosilicate (TEOS). A silica mass loading of 17% as judged by thermogravimetric analysis (TGA) produces a highly transparent dispersion, and ...

Advanced Science, EarlyView.Ti substitution stabilizes Co‐free high‐Ni layered oxides through both structural and electronic effects. TiO6 octahedra act as compensatory structural units that help interrupt cooperative Jahn–Teller distortion and suppress detrimental phase transitions, while the electron‐withdrawing inductive effect of Ti stabilizes the oxygen lattice. As a result,

Angewandte Chemie, EarlyView.Efficient photocatalytic nitrate‐to‐ammonia conversion is achieved over an atomically precise Cu4I4 motif through dual‐site cooperation. Lewis‐acidic Cu centers promote nitrate adsorption and activation, while adjacent I sites facilitate active hydrogen generation for stepwise hydrogenation.
