Advanced Materials, EarlyView.We identify strong anisotropy in the upper critical field and magnetoresistance in the kagome superconductor LaRu3Si2, revealing pronounced electronic anisotropy. Uniaxial stress enhances magnetoresistance and Tc, with a positive correlation suggesting an electronic pairing mechanism.

Photo‐ and Thermally‐Induced Huge Layer Decoupling in Twisted Bilayer WSe2
Advanced Materials, EarlyView.A newly developed automated dark‐field tomography visualizes twist‐angle‐dependent structural relaxation and quantifies 3D structures in twisted bilayer WSe2. This approach reveals the evolution of local stacking configurations, thermally induced sub‐ångström interlayer decoupling, and light‐driven interlayer expansion on picosecond timescales ...

On the non-orthogonality problem in the description of quantum devices [PDF]
, 1999 An approach which allows to include the corrections from non-orthogonality of electron states in contacts and quantum dots is developed. Comparison of the energy levels and charge distributions of electrons in 1D quantum dot (QD) in equilibrium, obtained

Electrically Coded Retinomorphic Spectrophotodetector
Advanced Materials, EarlyView.Self‐powered retinomorphic pyro‐photodetector is demonstrated that avoids machine‐learning post‐processing and covers 365–940 nm. Electrostatic balancing of built‐in potential produces an electrical wavelength code, delivering <3 nm wavelength decoding accuracy with ∼46 µs response.

Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements
Advanced Materials, EarlyView.Twisted oxide membranes containing volatile elements often suffer from amorphous interfacial dead layers that suppress coupling. An oxygen‐annealing strategy establishes atomically coherent and chemically bonded interfaces in twisted NaNbO3 membranes, enabling coherent oxide moiré architectures in volatile‐element‐containing systems.

Advanced Materials Interfaces, EarlyView.Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...
