Method: The materials used in the study were: 1) Macor, (Precision Ceramics UK) 2) BioMinF: 500gm of glass frit (Cera Dynamics Ltd, UK) and 3) Sylc: Sylc 45S5 glass (Velopex International, UK). An AquaCare Air Abrasion & Polishing System (Velopex) with a hand piece with a 0.8 mm diameter tip was used with a 2mm thick Macor sheet with a feed rate of 1 and an air pressure of 2 bar. The BioMinF glass was milled for 45 seconds in five batches each containing 100 gm of BioMinF frit using a milling machine (Gy-Ro Mill, Glen Creston, and London). The angular particles produced were separated using different sieves to produce <38 micron, 38-63 microns, 63-80 microns, 80-125 microns and 125-250 microns particle size(s) respectively. -

Copper is known to be an antibacterial agent, which could potentially be a safer alternative to doping materials with antibiotics. Additionally, the structural effects of copper in the glass were studied, as the glass structure plays an important role in its bioactivity in the physiological solutions. This leads to the possibility of achieving antibacterial glass that can serve as a bioactive glass for skeletal tissue. bioRxiv preprint doi: https://doi.org/10.1101/2020.01.24.918524; this version posted January 25, 2020.

A Bright Future for Glass-Ceramics
A bright future for glass-ceramics From their glorious past, starting with their accidental discovery, to successful commercial products, the impressive range of properties and exciting potential applications of glass-ceramics indeed ensure a bright future! by Edgar Dutra Zanotto lass-ceramics were discovered – somewhat accidently G – in 1953. Since then, many exciting papers have been published and patents granted related to glass-ceram- ics by research institutes, universities and companies worldwide. Glass-ceramics (also known as vitro- cerams, pyrocerams, vitrocerâmicos, vitroceramiques and sittals) are produced by controlled crystal- lization of certain glasses – generally induced by nucleating additives. This is in contrast with sponta- neous sur- face crys- tallization, which is normally not wanted in glass manufacturing. They always con- tain a residual glassy phase and one or more embedded crystalline phases. The crystallinity varies between 0.5 and 99.5 percent, most frequently between 30 and 70 percent. Controlled ceramization yields an (Credit: Schott North America.) array of materials with interesting, sometimes unusual, combinations of properties. American Ceramic Society Bulletin, Vol. 89, No. 8 19 A bright future for glass-ceramics Unlike sintered ceramics, glass- ceramics are inherently free from poros- ity. However, in some cases, bubbles or pores develop during the latter stages of crystallization. Glass-ceramics have, in principle, several advantages. • They can be mass produced by any glass-forming technique. • It is possible to design their nano- structure or microstructure for a given application. Fig. 1. Standing, from left to right, TC-7 members Ralf Muller, Guenter VoelKsch, Linda • They have zero or very low porosity.
