Self‐Healing Hydrogel Dressing with Solubilized Flavonoids for Whole Layer Regeneration of Diabetic Wound

open access: yesAdvanced Healthcare Materials, EarlyView.
High glucose‐ and acid‐responsive hydrogel with dynamic covalent bond solubilized with flavonoids (Gel‐Flavonoids) is designed for diabetic wound healing. The Gel‐Flavonoids adapt to irregular wound shapes and release antioxidants in high‐glucose environments, effectively reducing reactive oxygen species.

Inverses of triangular matrices and bipartite graphs [PDF]

open access: yesarXiv, 2013
To a given nonsingular triangular matrix A with entries from a ring, we associate a weighted bipartite graph G(A) and give a combinatorial description of the inverse of A by employing paths in G(A). Under a certain condition, nonsingular triangular matrices A such that A and A^{-1} have the same zero-nonzero pattern are characterized.

Jordan automorphisms, Jordan derivations of generalized triangular matrix algebra

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
We investigate Jordan automorphisms and Jordan derivations of a class of algebras called generalized triangular matrix algebras. We prove that any Jordan automorphism on such an algebra is either an automorphism or an antiautomorphism and any Jordan ...
