Analysis on Alternatives for HCFCs with Low Greenhouse Effect

open access: yesZhileng xuebao, 2011
After introducing the state of arts of HCFCs alternatives,the thermodynamic properties,cycling performance and flammability of the typical HCFCs refrigerants R22 and R502 and their traditional substitute refrigerants(R410A,R407C,R404A,R507A),and several ...

Physicochemical and Mechanical Characterization of Commercial Collagen‐Based Wound Dressings

open access: yesAdvanced NanoBiomed Research, EarlyView.
Commercial collagen‐based wound dressings are systematically compared to reveal how porous architecture governs hydration‐driven swelling and mechanical adaptation. Distinct structure–function relationships are identified, showing that wet‐state elasticity and conformability emerge from material composition and processing rather than manufacturer ...
