Organoid Brain‐Machine‐Interface Devices for Central Nervous System Repair
Advanced Science, EarlyView.We envision organoid brain‐machine‐interface (Organoid‐BMI) devices as new biohybrid bidirectional communication pathways to connect the human CNS and the external world for personalized CNS repair and regeneration. ABSTRACT Central nervous system (CNS) repair and regeneration suffer from tremendous clinical challenges due to current limitations in ...

Advanced Science, EarlyView.A weakly solvating fluorinated cosolvent (1200ET) enables precise solvation‐power regulation in Li–S batteries, decoupling interfacial stabilization from sulfur redox kinetics. This approach suppresses polysulfide dissolution while preserving reaction kinetics, leading to a stable Li metal interface and high‐energy multilayer pouch cells, revealing a ...

An exciting Approach to Theoretical Spectroscopy
Advanced Science, EarlyView.ABSTRACT Theoretical spectroscopy, and more generally, electronic‐structure theory, are powerful concepts for describing the complex many‐body interactions in materials. They cover methods from ground‐state properties to lattice excitations and light‐matter interaction, including time‐resolved variants.

Advanced Science, EarlyView.We report the fast generation of biocompatible solutions of highly 13C‐hyperpolarized (≈11%) partially‐deuterated ketoisocaproate within <6 min using spin‐lock‐induced crossing and reversible exchange with parahydrogen (SLIC‐SABRE). This enables rapid detection of branched‐chain‐amino‐acid transferase 1 (BCAT1) protein expression and investigation of ...
