Heat Transfer Performance of Biphilic Surfaces With Diatomite‐Based Composite Coatings in a Closed Thermosyphon System

Heat Transfer, Volume 55, Issue 3, Page 1608-1638, May 2026.
ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...

Interactions Between Dissolved Organic Carbon and Aluminium Activity in Tropical and Temperate No‐Till Agroecosystems

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
Conceptual model of depth‐stratified soil acidification under long‐term no‐till in temperate (Washington, USA) and tropical (Brazilian Oxisol) systems. Nitrogen inputs promote surface acidification (↓pH) and increased Al3+ activity, while lime or silicate amendments modify base cation dynamics. Increased DOC–Al complexation reduces free Al3+ and alters

Fetoscopic laser ablation vs standard management for Type‐II and Type‐III vasa previa

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 320-328, March 2026.
ABSTRACT Objective The standard management (SM) for vasa previa (VP) includes antepartum inpatient admission at 28–32 weeks' gestation followed by Cesarean delivery at 34–37 weeks. Case reports and case series have reported on fetoscopic laser ablation (FLA) as an alternative management approach for Types‐II and ‐III VP.
