Inhibitory Decay and Supercritical Brain Dynamics During Sleep Deprivation

Advanced Science, Volume 13, Issue 45, 13 August 2026.
Sleep deprivation progressively shifts human brain dynamics from near‐critical toward supercritical states, as revealed by neuronal avalanche analysis of resting‐state fMRI. These changes track subjective sleep pressure rather than vigilance lapses and show marked network heterogeneity. A circuit model suggests that reduced inhibitory efficacy provides

A Strong Lewis Acidic Diethylsilylium Catalyst for Direct Sulfonamidation of Challenging Ketones

Advanced Science, Volume 13, Issue 46, 17 August 2026.
Low‐substitution‐order silylium ions (R2HSi+) exhibit exceptional Lewis acidic activity. We report diethylsilylium‐catalyzed reductive sulfonamidation of functionalized ketones to access β‐amino esters. The in situ generated ion pair shows enhanced reactivity, with diethylsilane serving as both reductant and precatalyst. The developed protocol proceeds

Supercritical CO2‐Induced Porous MXene Films for Electromagnetic Interference Shielding and Infrared Stealth

Advanced Science, Volume 13, Issue 48, 28 August 2026.
The phase transition of supercritical CO2 induces the foaming of dense MXene film without compromise inherent structure of MXene nanosheet. The foamed porous MXene film manifests remarkable EMI shielding and infrared thermal camouflage performances. Moreover, the foaming strategy is broadly adaptable and can be extended to other two‐dimensional films ...

Self‐Similar Blowup for the Cubic Schrödinger Equation

Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1831-1918, August 2026.
ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Integrated Evaluation of the Multifunctional Bioactivity of Curcuma zedoaria (Christm.) Roscoe Essential Oil: Antimicrobial, Insecticidal, and Postharvest Effects on Fresh Ginger

eFood, Volume 7, Issue 4, August 2026.
Multifunctional bioactivity of Curcuma zedoaria essential oil. ABSTRACT Plant‐derived essential oils are increasingly investigated as sustainable alternatives for food preservation and crop protection; however, their multifunctional applicability under postharvest conditions remains insufficiently explored.
