Clustering and percolation in lithium borate glasses [PDF]

open access: yesThe Journal of Chemical Physics, 2004
Molecular dynamics simulations are carried out in xLi2O–(1−x)B2O3 glasses (x=0.2–0.6) at T=1250 K, where cluster size distributions for Li cations and nonbridging oxygen (NBO) atoms are calculated. The existence of percolating clusters above x=0.3 places the percolation threshold between x=0.3 and 0.4 for the system under investigation, which is ...

Cobalt-containing borate bioactive glass fibers for treatment of diabetic wound

open access: yesJournal of Materials Science: Materials in Medicine, 2023
Impaired angiogenesis is one of the predominant reasons for non-healing diabetic wounds. Cobalt is well known for its capacity to induce angiogenesis by stabilizing hypoxia-inducible factor-1α (HIF-1α) and subsequently inducing the production of vascular
