Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

Advanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

Estimation of Diffuse Hydrocarbon Leakages from Petrochemical Factories [PDF]

Journal of the Air Pollution Control Association, 1983
Tracer experiments were carried out to quantify the diffuse leakages of hydrocarbons at two petrochemical complexes in Norway. Single tracer (SF6) and dual tracer (SF6/CBrF3) experiments were performed for different test designs and different meteorological conditions.

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Study on Leakage Diffusion of R1234yf Vehicle Air Conditioner

Zhileng xuebao, 2022
The thermal management system of electric vehicles is different from that of traditional passenger vehicles. For electric vehicles with a heat pump system and liquid cooling battery, the refrigerant charge is increased by 400–800 g compared with traditional air conditioning. If a combustible refrigerant is used, any leakage will spread to the passenger
