Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

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 ...

Response characteristics of methane–air and propane–air premixed flames to sinusoidal oscillations in equivalence ratio (Effects of Lewis number and preferential diffusion)

Journal of Thermal Science and Technology
Flames propagate in mixture flows with inhomogeneous concentration distributions in practical combustors, such as gasoline direct-injection engines and gas turbine engines. Clarifying the effect of fuel-type differences on the response characteristics of

Metallofullerenol Sc3N@C80(OH)18: A New Generation Radioprotector Protecting Human Erythrocytes Against Multiple Biochemical Damage Modes Upon Gamma Irradiation, Identifying It as a Scavenger of Short‐ and Long‐Lived Radicals

Advanced Healthcare Materials, EarlyView.
Metallofullerenol Sc3N@C80(OH)18 demonstrates strong radioprotective properties as a scavenger of both short‐ and long‐lived radicals. The study reveals protection of human erythrocytes from γ‐radiation–induced biochemical damage via post‐irradiation removal of primary and secondary reactive oxidants, supported by pulse radiolysis kinetics.

Dual‐Functional Polyphosphoesters for Gene Delivery: Synergistic Effects of Guanidinium and Hydrophobic Side Chains in Degradable Polymers

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 ...

Effect of Flame Stabilizer Design on Performance and Exhaust Pollutants of a Two-Row Swirl-Can Combustor Operated to Near-Stoichiometric Conditions [PDF]

Emissions and performance characteristics were determined for two full annulus modular combustors operated to near stoichiometric fuel air ratios. The tests were conducted to obtain stoichiometric data at inlet air temperatures from 756 to 894 K and to ...
