Mesoporous Bioactive Glasses: A Powerful Tool in Tissue Engineering and Drug Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This work is a comprehensive revision of bioactive glasses (BGs), pioneered by Prof. L.L. Hench, which are key in bone repair and regenerative medicine. Sol–gel methods and mesoporous designs enhanced their bioactivity, ions, and drug delivery. BGs now support gene therapy and 3D‐printed scaffolds, enabling personalized, multifunctional treatments in ...

Preparation of Bifunctional Orthosilicophosphate MgO‐CaO‐ZnO‐P2O5‐SiO2 Glasses: in vitro Evaluation of Antibacterial Activity and Osteoblast Gene Expression Behavior

open access: yesAdvanced Healthcare Materials, EarlyView.
Bifunctional ZnO‐containing orthosilicophosphate glasses (SPGs) composed mainly of orthotetrahedral groups with the unique glass network structure without long‐chain units are prepared via melt‐quenching. The glasses exhibit excellent antibacterial activity and upregulate the expression of osteogenic markers by releasing inorganic ions.

The comparison of cutting tools for milling of dental impression made from materials Ti6Al4V ELI and CoCr [PDF]

open access: yes, 2016
Cílem této práce je porovnání dvou vybraných fréz. Obě frézy jsou ze slinutých karbidů, proto teoretickou část věnujeme těmto materiálům. Porovnáváme chemické složení i mechanické a fyzikálních vlastnosti jednotlivých materiálů fréz.
