Compostable and Recyclable Baroplastic Triblock Copolymers Enable Low‐Energy Polymer Processing

open access: yesSmall, EarlyView.
Baroplastic Poly(L‐lactide)‐block‐poly(ethylene glycol)‐block‐poly(L‐lactide) triblock copolymers enable ambient‐temperature processing under moderate pressure, reducing energy demand while preserving polymer integrity. The materials show rapid industrial compostability, effective chemical and physical recyclability, and compatibility with heat ...

Reconfigurable Nanogap SERS for Multiscale Molecular Sensing on Curved Surfaces

open access: yesSmall, EarlyView.
Reconfigurable Au‐coated SMP nanocomposites enable adaptive SERS through reversible tuning of Au─Au nanogaps. Embedded AgNPs serve as photothermal triggers and reinforcements. Wide gaps facilitate macromolecule detection, while narrowed gaps enhance small‐molecule signals for reliable multiscale sensing on curved surfaces.

Fluorinated copolymer resists for high‐resolution negative‐tone lithography: Preparation and patterning performance

open access: yesSmart Molecules, EarlyView.
Electron‐beam induced C–F cleavage in –CF3 generates F−, which abstracts a proton to form the acid that catalyzes tBMA deprotection during post‐exposure baking. This self‐sensitization mechanism enables the precise formation of high‐resolution negative‐tone patterns with enhanced sensitivity and resolution.

White light emitting molecular logic gates

open access: yesSmart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.

Synthesis of Patchy Particles at Phase Boundaries

open access: yesSmall Methods, EarlyView.
The various strategies employed for synthesizing complex multifunctional patchy particles are reviewed, with, as a guideline, the type of phase boundary (solid‐gas, liquid‐gas, solid‐liquid, and liquid‐liquid), that serves as the crucial ingredient for symmetry breaking.

Scaffolds for cell transplantation in neurology—The suitability of a thermoreversible gelation polymer: Our perspectives

open access: yesJournal of Spinal Surgery, 2014
Clinical translation of cell-based therapies in neurology, especially the spinal cord injury and damage to the brain, have been marred by several hurdles [Dedeepiya VD et al Expert Opinion on Biological Therapy (In print)] and one significant among them ...

Gas check prevention during calendering of poly(vinyl chloride) films using poly(caprolactone)‐based additives

open access: yesJournal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 441-452, March 2025.
Three poly(caprolactone) (PCL)‐based additives of differing molecular weights were used as a secondary plasticizer to prevent gas checks in PVC films produced through calendering. Results showed that chemical and physicochemical properties influence the prevention or reduction of gas checks, unlike rheological properties including complex viscosity and

Fracture load and three‐dimensional internal void analysis of direct composites used to restore worn molars

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This study evaluated (1) the load‐bearing capacity of molars restored with direct occlusal veneers fabricated either from short‐fiber‐reinforced composite (SFRC) or particulate‐filled composite (PFC) and the presence of internal voids within the materials, and (2) effect of water storage on the fracture load and correlation between internal ...

Erythrocyte ‘Feierzeit’ reaction: Novel filamentous and vesicular response to n‐butyl acetate

open access: yesJournal of Microscopy, EarlyView.
Abstract Human erythrocytes (red blood cells; RBCs) undergo spontaneous disassembly after several hours of exposure to n‐butyl acetate (nBA). Images of the morphological changes were captured in time‐lapse sequences using differential interference contrast (DIC) light microscopy.
