A Full Physical Strategy for Electrical Contacts on Laser‐Induced Graphene (LIG) Electrodes

open access: yesAdvanced 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.

Flexible and Transparent Ga2O3/NiO Photovoltaic Diode for Full‐Wave Rectification in Wearable Optoelectronics

open access: yesAdvanced 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.

Chemical Switching Between B2N and B2C Homoaromaticity

open access: yesAngewandte 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.

Import Wheat Tenders and the Effects of the Russian Invasion

open access: yesAgribusiness, EarlyView.
ABSTRACT Risk and volatility for many commodities escalated sharply following the Russian invasion of Ukraine, creating numerous uncertainties for trading firms and importers. The purpose of this study is to analyze the bidding behavior in Egyptian wheat import tenders in the pre‐ and post‐invasion periods.

Assessing the contribution of multiply scattered radio waves to the impulse response of a wireless channel

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки
Using a three-dimensional topographic map of a typical microdistrict in Kazan, multipath radio wave propagation in mobile radio communication systems was modeled by the method of ray tracing.

In Situ Contact Angle Measurement for Autonomous Spin Coating in Self‐Driving Labs

open access: yesAdvanced Intelligent Discovery, EarlyView.
A vision‐based add‐on transforms commercial spin coaters into autonomous modules of Self‐Driving Labs. Combining a width‐scaled U‐Net with classical geometric analysis, the system simultaneously measures contact angles and estimates substrate pose using a single camera.
