Combined Analysis of the Mechanical Behavior in the Time and Frequency Domain of a Viscoelastic Brain Phantom Material

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT The mechanical characterization of brain tissue in multiple time scales is often limited by inconsistent or contradicting responses when different experiments are used. The main reason for theses discrepancies are variations in the experimental setups, as brain tissue is sensitive to changes in the time and length scale.

Multilayer Cellulose Acetate–Viscose Films for Bio‐Based, Bio‐Degradable Packaging Applications

Packaging Technology and Science, Volume 39, Issue 6, Page 685-695, June 2026.
Cellulose acetate (CA) and cellulose foils stick together comprehensively after mild cellulose sodium hydroxide treatment and heated compression. For combined foils, water barrier properties correlate with CA thickness. Oxygen permeation suffers due to the sodium hydroxide pre‐treatment induced foil changes. The composite represents a biodegradable and

Exploring the Reactivity of Perphenylheptasilanes: Synthesis of Terminally Functionalized Derivatives

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 7, 6 May 2026.
Different methods to prepare 1,7‐disubstituted tetradecaphenylheptasilanes are explored. The triflated heptasilane TfO‐(SiPh2)7‐OTf reacts with alkali metal halides to produce the 1,7‐dihalogenides X‐(SiPh2)7‐X (X = F, Cl, Br, I). The 1,7‐dihydrogen derivative H‐(SiPh2)7‐H is obtained with LiAlH4 or (i‐Bu)2AlH as reducing agents.

MXene‐Enabled Wearable Biosensors: A Design Framework for Autonomous Biosensing

ChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Bridging nanoscale innovation with MXene to real‐time, patient‐centered health systems. MXenes, a rapidly expanding family of two‐dimensional transition metal carbides and nitrides, have emerged as leading materials for wearable bioelectronics due to their metallic conductivity, termination‐rich surfaces, mechanical compliance, and tunable interlayer ...

Octupolar AIEgens Photosensitizers With Enhanced Molar Absorptivity for Near‐Infrared Phototheranostics

Aggregate, Volume 7, Issue 5, May 2026.
Symmetry‐guided molecular engineering transforms dipolar AIEgens into octupolar AIEgens (D(A)3) with enhanced NIR‐II absorptivity. The octupolar architecture activates additional S0→S2 transitions and promotes efficient intersystem crossing, leading to strong reactive oxygen species generation.
