Effects of boundary layer displacement and separation on opposed-flow flame spread [PDF]
, 1997 An analysis is presented of the viscous-inviscid Interaction region around the tip of a flame spreading over the surface of a solid fuel in a forced laminar high reynolds number air stream that opposes the flame propagation. Through the interaction, the

Advanced Healthcare Materials, EarlyView.Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Buoyancy Effects on Concurrent Flame Spread Over Thick PMMA [PDF]
The flammability of combustible materials in a spacecraft is important for fire safety applications because the conditions in spacecraft environments differ from those on earth. Experimental testing in space is difficult and expensive.

Catalysts for polyimide foams from aromatic isocyanates and aromatic dianhydrides [PDF]
, 1979 Polyimide foam products having greatly improved burn-through and flame-spread resistance are prepared by the reaction of aromatic polyisocyanates with aromatic dianhydrides in the presence of metallic salts of octoic acid. The salts, for example stannous

Advanced Healthcare Materials, EarlyView.This study presents guanidinium‐ and indole‐functionalized polyphosphoesters as degradable, non‐viral gene delivery vectors. Through precise tuning of charge density and hydrophobicity, these polymers form stable polyplexes with low toxicity. Remarkably, minor structural changes yield up to 200‐fold differences in transfection efficiency, highlighting ...
