Droplet Formation and Impingement Dynamics of Low-Boiling Refrigerant on Solid Surfaces with Different Roughness under Atmospheric Pressure

Applied Sciences, 2022
The dynamic behavior of droplet impingement is one of the most important processes of spray cooling. Although refrigerants with a low boiling point have been widely used in spray cooling, their high volatility makes it difficult to generate a stable ...

The Gut Commensal Butyricimonas Virosa Modulates Gut Microbiota‐Dependent Thiamine Metabolism and Attenuates Mouse Steatotic Liver Disease

Advanced Science, EarlyView.
This study reveals that dietary stachyose enriches Butyricimonas virosa, effectively attenuating metabolic dysfunction‐associated steatotic liver disease (MASLD). Mechanistically, B. virosa enhances gut thiamine monophosphate synthesis, which elevates hepatic thiamine pyrophosphate levels.

The Influence of Rotation on Impingement Cooling [PDF]

Volume 4: Heat Transfer; Electric Power; Industrial and Cogeneration, 1996
The objective of the present work is the experimental investigation of the effects of rotation on the heat transfer due to a single row of circular jets impinging on a curved surface, relevant to turbine blade cooling. The local transfer coefficients were determined by means of the naphthalene sublimation technique using the analogy between heat and ...

Self‐Healing Starch‐Based Ionogels with Hydroneutral Dipole–Dipole Interactions

Advanced Science, EarlyView.
This work introduces starch‐based, conductive, underwater‐healable, and transparent ionogels for soft electronics (SCUTEs). Starch macromolecules are partially substituted with cyanoethyl groups and incorporated with hydrophobic ionic liquid. The polar yet hydroneutral cyanoethyl groups facilitate strong dynamic dipole–dipole interactions that remain ...
