Four brands of glass-ionomer cement (Fuji IX GP, Riva, Ketac Molar and Chemfil Superior) have been stored in aqueous media comprising distilled water, or phosphate buffer solutions at pH 5.42, 6.91 and 8.13 at 37°C for 7 days. Cements differed widel

The surface properties of G338 ionomer glass powder, both in as-received and heat-treated, have been studied in order to identify the reason that heat-treatment gives a cement that sets quicker but is weaker. Samples of G338 glass were analysed by X-

Samples of the ionomer glass known as G338 have been heated at 240°C for 24 hours, after which they lost 1.19 % (Standard deviation 0.16%) of their original mass. This loss was attributed to removal of water, as both molecular water and the product

A study is reported in which the interaction between a typical ionomer glass and water was evaluation in order to evaluate the importance of hydration in the setting of glass-ionomer cements. Glass G338 was mixed with water and the slurries were allo

Water uptake in two glass-ionomer cements stored in various aqueous ionic solutions has been studied following a 6-week storage period, and the bound/unbound water ratio has been determined. Both types of cement took up water with net uptake varying

Trapped ultracold alkali-metal atoms can be used to measure pressure in the ultra-high-vacuum and XHV pressure regimes, those with p < 10−6 Pa. This application for ultracold atoms relies on precise knowledge of collision rate coefficients of alkal

Abstract There exist multiple ways to cool neutral molecules. A front runner is the technique of buffer gas cooling, where momentum-changing collisions with abundant cold noble-gas atoms cool the molecules. This approach can, in principle, produce th
