Gamma Irradiation‐Based Free Radical Grafting of N‐Hydroxyethyl Acrylamide onto Poly[(R)‐3‐hydroxybutyrate]

open access: yesMacromolecular Rapid Communications, EarlyView.
This work demonstrates successful gamma‐radiation‐induced grafting of N‐hydroxyethyl acrylamide onto poly[(R)‐3‐hydroxybutyrate], producing substantial changes in material properties. Grafting generated a biphasic, less crystalline structure with enhanced thermal stability, elongation (65%), toughness (378% increase), and exceptional water uptake (610 ...

Wet‐Transferred MoS2 on Passivated InP: A Van der Waals Heterostructure for Advanced Optoelectronic Applications

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 5, May 2025.
This study presents a photodetector based on atomically thin MoS2 on an InP substrate, forming an n‐MoS2/p‐InP type‐II staggered heterojunction. The device exhibits excellent rectifying properties with an ideality factor of 1.57 and achieves a peak photoresponsivity of 960 mA W−1, while MoS2 provides stable passivation for InP. III–V semiconductors are

Method of meal delivery influences estimates of postprandial metabolism and alkaline tide in a benthic fish

open access: yesJournal of Fish Biology, EarlyView.
Abstract Intragastric gavage is widely used in studies of digestive physiology to deliver standardised meals, yet it remains unclear whether it elicits postprandial metabolic and acid–base responses comparable to voluntary feeding. Here, we tested whether the method of meal delivery affects the magnitude and timing of the postprandial rise in metabolic
