Unveiling Unidirectional Transport within Janus Membranes
Small Structures, Volume 6, Issue 4, April 2025.GA: A three‐stage model is proposed to describe unidirectional transport through Janus membranes, encompassing liquid intrusion, capillary wetting, and liquid transport. The mechanisms of liquid intrusion include direct‐contact‐driven intrusion in bilayer structures and surface‐energy‐driven intrusion in gradient structures.

Andrology, Volume 13, Issue 2, Page 184-201, February 2025.Abstract Background Ion channels are essential for differentiation and maturation of germ cells, and even for fertilization in mammals. Different types of potassium channels have been identified, which are grouped into voltage‐gated channels (Kv), ligand‐gated channels (Kligand), inwardly rectifying channels (Kir), and tandem pore domain channels (K2P).

Journal of Analytical Methods in Chemistry, Volume 2025, Issue 1, 2025.A novel, sensitive, and efficient method was developed for the determination of paraquat in soil samples, centered on solid‐phase microextraction using hollow fiber–supported ZIF‐8@GO reinforced sol–gel combined with UV‐Vis spectrophotometry at 257 nm. Silica‐based ZIF‐8@GO was synthesized through sol–gel technology by reacting tetraethyl orthosilicate

Vascular Development of Fetal and Postnatal Neocortex of the Pig, the European Wild Boar Sus scrofa
Journal of Comparative Neurology, Volume 532, Issue 12, December 2024.Species silhouettes are adapted from Wahle et al., 2022. ABSTRACT The development of the brain's vascular system is a predominantly prenatal process in mammalian species and is required for neurogenesis and further brain development. Our recent work on fetal pig has revealed that many neurodevelopmental processes start well before birth and proceed ...
