Excited State Branching Processes in a Ru(II)‐Based Donor–Acceptor–Donor System
Chemistry – A European Journal, Volume 31, Issue 31, June 3, 2025.The photoinduced electron transfer processes in a Ru(II)‐based push–pull–push architecture which combines an inorganic and organic chromophore are elucidated in a joint spectroscopic‐theoretical approach. The applied design concept allows the excited state to be localized away from the metal onto the organic chromophore.

Angewandte Chemie, Volume 137, Issue 23, June 2, 2025.Diese Studie zeigt zum ersten Mal einen enormen Vorteil des intermetallischen Clathrats Ba‐Ni‐Ge in Massenform gegenüber metallischem Nickel als hochleistungsfähigen alkalischen OER‐Präkatalysator. Es zeigt bemerkenswerte Aktivität und Stabilität bei hohen Stromdichten, was durch einen umfassenden Rekonstruktionsprozess ermöglicht wird, der eine poröse

Angewandte Chemie International Edition, Volume 64, Issue 23, June 2, 2025.For the first time, this study demonstrates a huge advantage of the clathrate Ba–Ni–Ge intermetallic bulk over metallic nickel as a high‐performance alkaline OER precatalyst. It displays remarkable activity and stability under high current densities, facilitated by a thorough reconstruction process that yields a porous and defective NiOOH ...

Femtosecond Pulse Shaping with Semiconductor Huygens' Metasurfaces
Advanced Optical Materials, Volume 13, Issue 16, June 6, 2025.Spatially variant silicon Huygens' metasurfaces enable femtosecond pulse shaping by tailoring the spectral phase and amplitude of incident pulses. Two key functionalities are demonstrated: temporal stretching and pulse splitting of an input Gaussian pulse.

Mimicking Symmetry‐Breaking Einstein Ring by Optical Lens
Advanced Photonics Research, Volume 6, Issue 6, June 2025.This article uses an optical lens to emulate the gravitational lensing effect and observe the Einstein ring (ER) patterns. The symmetry‐breaking ER, i.e., Einstein cross, is observed utilizing a rotation‐symmetry‐breaking hemi‐ellipsoid lens. Deformed Einstein cross patterns induced by noncollinearly alignment of the light source–lens–observer are ...

Advanced Science, Volume 12, Issue 21, June 5, 2025.How do chemical and physical processes involving multiple phases develop on compact astrophysical objects such as white dwarf stars? Herein, entropy‐driven self‐assembly of rod‐shaped nanoparticles in centrifugal acceleration fields up to 7251 times the gravity of Earth is investigated, where strong acceleration fields accelerated the kinetics of phase

Asian Journal of Organic Chemistry, Volume 14, Issue 6, June 2025.Benzannulation of dibenzopentalene leads to dinaphthopentalenes, of which, we synthesized the linear and anti‐isomer as thioethers with various substituents. Depending on the annulation pattern, their optoelectronic properties strongly differ. Of particular interest, is an increased antiaromaticity resulting from the anti‐annulation pattern, indicated ...

Alzheimer's &Dementia, Volume 21, Issue 6, June 2025.Abstract INTRODUCTION The extent to which Alzheimer's disease (AD) concerns relate to pathological changes in cognitively unimpaired populations is unclear. METHODS We analyzed screening data from the Anti‐Amyloid Treatment in Asymptomatic Alzheimer's (A4) study to determine if AD concerns are associated with amyloid burden in cognitively unimpaired ...
