Electrospun PVA Scaffolds Containing MCM‐41/CNC Nanocomposites for Controlled Drug Release in Wound Dressings

open access: yesPolymer Engineering &Science, EarlyView.
Cellulose nanocrystals extracted from Mauritia flexuosa petiole were combined with MCM‐41 mesoporous silica to create a diclofenac‐loaded hybrid nanocomposite. Incorporation into electrospun PVA scaffolds enabled controlled diclofenac release and high cell viability, highlighting their potential for localized drug delivery.

Design and optoelectronic profiling of a semicrystalline thiophene–phenylene copolymer for advanced organic electronics

open access: yesPolymer International, EarlyView.
A new semicrystalline copolymer, PTBT‐3OBu, was synthesized. Intramolecular S···O conformational locks induce high backbone planarity, promoting strong interchain coupling and molecular ordering in thin films, seen in an optical red shift. This synergy between planarity and semicrystalline morphology is promising for photovoltaic and electrochromic ...

Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

open access: yesStructural Concrete, EarlyView.
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.

Geometrical isomerization of hydroxycinnamic acid under UV‐light: Structural plasticity as a driver of metabolite complexity

open access: yesPhotochemistry and Photobiology, EarlyView.
UV irradiation drives metabolite complexity through photoisomerization of hydroxycinnamic acid‐containing compounds in plants. The olefin functional group of hydroxycinnamic acid enables structural plasticity through trans/cis isomerization. Multiple chromophores within a molecule can amplify UV‐induced transformations.

Effects of Wall‐to‐Floor Interactions on Seismic Response of Platform‐Type CLT Buildings

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2880-2896, September 2026.
ABSTRACT Platform‐type cross‐laminated timber (CLT) buildings feature discontinuous wall segments supported by CLT floors. In practice, CLT floors are often treated as rigid diaphragm, yet the wall‐to‐floor interactions (WFIs) associated with flexibility of floors remain insufficiently investigated during seismic performance assessment.

Sequence‐encoded determinants drive distinct early aggregation pathways and different structural outcomes in PNT1 fibrils across Henipavirus members

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract Protein aggregation is increasingly recognized as a biologically relevant process in viral proteins, yet the molecular determinants governing such phenomena remain poorly understood. Intrinsically disordered proteins (IDPs) are ubiquitous in viral proteomes, where conformational plasticity not only enables functional diversity but also permits
