Special Issue Information

Dear Colleagues,

This Special Issue is a platform to present new advancements in glass technology. We focus on testing the functional properties of glasses and their composites. We believe that glass, due to a combination of its properties, is a unique material that has a wide array of applications. Glass is difficult to replace in some cases due to its transparency, thermal and chemical resistance, and mechanical strength. These properties can be modified over a wide range because glasses can be incorporated in various glass-forming systems with variable compositions. This area of interest is extended to glass composites, in which glass can act as a functional element or a filler/host. This thereby paves the way as a possible direction for new studies that can be presented in this Special Issue. There are no limits on research topics. However, the current advancements in glass research are related to energy technology (renewable energy systems, glassy electrolytes), glass recycling (i.e., photovoltaic panels), biotechnology (bioactive and biocompatible glasses), optoelectronics (laser matrix, amplifiers, optical fibers), the detection and protection of high-energy radiation (immobilization of hazardous waste, dosimeters), unconventional methods of obtaining the amorphous phase, etc.

Silicate and borate bioactive glasses have been reported to create alkaline conditions by rapidly releasing ions when reacting in aqueous solution. At certain levels, this alkaline solution can negatively affect cell viability. Adding phosphate ions to the glass composition can control the degradation rate of bioactive glasses and create a neutral pH environment. This study evaluated a series of borophosphate bioactive glasses (BPBGs) with nominal molar compositions 16Na2O-24CaO-xB2O3-(60-x)P2O5, where x = 0, 40, or 60. The phosphate (X0) glass (PBG) produced an acidic solution when dissolved in water; the borate (X60) glass (BBG) produced an alkaline solution, and the BPBG glass produced a pH-neutral solution. These three glasses were evaluated using adipose stem cells (ASCs), a cell population known for their therapeutic abilities. The effects of each glass on the pH of cell culture, ions released during degradation, and on ASC functions, including viability, migration, angiogenic ability, differentiation, and protein secretions, were evaluated. The X40 BPBG created a physiologically neutral pH in cell culture media after 24 h. The X0 phosphate glass promoted ASC migration, while the highly alkaline X60 borate increased the angiogenic ability of ASCs. These results indicate that BPBG can be used safely in cell culture studies and customized for specific biomedical applications. Full article
