THE ACTIVATION OF THE DERMIS EXTRACELLULAR MATRIX SYNTHESIS AFTER THE THERMAL BURN
Morphological newsletter, 2023 It is known that the healing of skin wounds of various etiologies is a multistage process characterized by certain intercellular interactions that affect the adhesion of dermal cells, their migration and differentiation. The modern strategy of tissue engineering mostly attracted for the use of the patient's own cells to create in vitro a vascularized ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions
Advanced Functional Materials, EarlyView.This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

PLANT MEDIATED GREEN SYNTHESIS OF ZINC OXIDE NANOPARTICLES FOR BURN WOUND THERAPY
International Journal of Advanced Research, 2020 In this changing world, we all are surrounded by the surmountable risk of getting injured. Amongst various risk factors, major burns are the most distressing and catastrophic. Burn wounds are not easy to heal via natural healing process and ultimately ended up with scar formation.

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
Advanced Functional Materials, EarlyView.We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...
