Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

A Full Physical Strategy for Electrical Contacts on Laser‐Induced Graphene (LIG) Electrodes
Advanced Electronic Materials, EarlyView.A fully dry fabrication strategy combining PVD and dual‐laser processing enables direct integration of laser‐induced graphene with metallic current collectors. Ultralow Au‐LIG contact resistance is achieved without binders, adhesives, or chemical treatments, while preserving electrochemical performance.

Chemical Switching Between B2N and B2C Homoaromaticity
Angewandte Chemie, EarlyView.We report the synthesis of homoaromatic 1‐aza‐2,4‐diazadiboretane with a bicyclic four‐membered NB2C motif and demonstrate experimentally and theoretically that the homoaromatic delocalization can also be chemically shifted from the B2N to the B2C moiety by deprotonation of the ring carbon atom.

IL-17 in the Rheumatologist’s Line of Sight
BioMed Research International, 2013 Over the past decades, the identification of several new cytokines, including interleukin (IL)-17 and IL-23, and of new T helper cell subsets, including Th17 cells, has changed the vision of immunological processes. The IL-17/Th17 pathway plays a critical role during the development of inflammation and autoimmunity, and targeting this pathway has ...

Advanced Electronic Materials, EarlyView.Flexible transparent electronics require efficient power management without sacrificing visibility or mechanical compliance. This work presents a room‐temperature‐fabricated amorphous Ga2O3/NiO heterojunction diode on a flexible substrate that enables full‐wave rectification, UV photovoltaic energy harvesting, and self‐powered photodetection.
