Stability of ceramic glaze compositions. Correlation between partial dissolution and rheological properties. Part 1
Society of Glass Technology (2012)When glaze compositions are prepared as aqueous suspensions, the frit is wet milled in an alumina ball mill with additives and water to obtain a glaze suspension with the appropriate rheological properties for subsequent ... -
Stereoisomerization of α-hydroxy-β-sulfenyl-α,β-dimethyl naphthoquinones controlled by nonbonded sulfur–oxygen interactions
Elsevier (2013-03)The anti α-hydroxy-β-sulfenyl-α,β-dimethyl naphthoquinones isomerize in basic media into syn/anti mixtures of isomers, giving the syn isomer as the major product. Conversely, anti α-hydroxy-β-alkoxy-α,β-dimethyl naphthoquinones ... -
Stiffness variation of porous titanium developed using space holder method
Maney on behalf of the Institute of Materials, Minerals and Nining (2011-07)The excellent properties of Ti have resulted in its generalised use for bone implants. However, Ti is very stiff in comparison with human cortical bone, and this creates problems of bone weakening and loosening of the ... -
