Effects of Ambient Moisture and Large‐Strain Dynamic Preloading on the Dynamic Properties of the EAC‐1A Regolith Simulant

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The EAC‐1A lunar mare simulant, a silty sand, was selected by the European Astronaut Center (EAC) for use in the LUNA analogue facility's lunar simulation testbed. Its stress‐ and strain‐dependent shear modulus and damping ratio were determined via resonant column testing on specimens prepared either from ambient moisture material or oven ...

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

Polymer 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

Polymer 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 ...
