Water‐Activated Phospholipid Phase‐Separation Gel as an Immunomodulatory Anti‐Adhesion Barrier for Postoperative Adhesion Prevention

open access: yesAdvanced Healthcare Materials, EarlyView.
A water‐activated phospholipid phase‐separation gel is repurposed as a drug‐free surgical barrier for postoperative adhesion prevention. Propylene glycol promotes rapid lamellar gel reinforcement, prolonged local retention, and tissue coverage, while phosphatidylcholine‐mediated immunomodulation suppresses inflammatory and fibrotic responses. This dual‐

Computed Tomography‐ and Photoacoustic Imaging‐Active Bioresorbable Electrospun Bismuth Nanoparticle‐Infused Small‐Diameter Vascular Grafts

open access: yesAdvanced Healthcare Materials, EarlyView.
A polymeric graft loaded with radiopaque bismuth nanoparticles is expected to undergo gradual polymer resorption and nanoparticle release. This design enables noninvasive, multimodal monitoring of device integrity, patency, and degradation using computed tomography alongside ultrasound and photoacoustic imaging over 12 weeks.

A New Variable Shear Capillary Viscometer

open access: yes, 1958
Since Newton's definition of viscosity does not lead to a useful description of non-Newtonian flow, two other model liquids, the Maxwell liquid and the Prandtl-Eyring liquid are discussed.

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

open access: yesAdvanced Materials, EarlyView.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

open access: yesAdvanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots

open access: yesAdvanced Materials, EarlyView.
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Dissolution behaviour of a binary mixture in a capillary tube

open access: yes
We develop a pore-level physical model for the process of miscible displacement through porous media. Using the network model, the current task is reduced to the study of the dissolution dynamics of a binary mixture within a single capillary tube.
