Topological Point Defects in SmC* Liquid Crystals Under Mechanical Disturbance
Tangetial air jet shear inducess island formation and nucleates topological point defects in uniform SmC films. Island bounded by edge dislocation loops shrink and transform into isolated point defects under continued shear. Mechanical perturbatio provides a controllable route for defect engineering in smectric liquid crystal thin films.

Light‑Driven Propulsion of Graphene Aerogels in Microgravity
Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

Marangoni Flow Before Carlo Marangoni
ABSTRACT In fluid dynamics, particularly in research on soft matter, it is well known that surface tension gradients drive fluid flow, a phenomenon known as Marangoni flow. The effect is named after Carlo Marangoni, who described it in 1865 as part of his doctoral thesis on droplets and liquid films. While Marangoni's contribution is rightly recognized,

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Gut Microbiota‐Linked Benefits of Low‐Intensity Pulsed Ultrasound Rejuvenate the Ageing Muscle
ABSTRACT Background Ageing is an inevitable biological process that contributes to increased prevalence of age‐associated diseases, including sarcopenia, defined by progressive loss of muscle mass, functional decline and a heightened risk of injury. Developing effective interventions remains a critical clinical priority.
