In 1998 the American Academy of Forensic Sciences celebrated its first 50 years of operation at its Golden Anniversary Meeting in San Francisco. In anticipation of that event, in 1991 the Academy created a committee to prepare a history of the organization. One of the products of that committee was a book, the principal author of which was one of the authors of this review (KSF). The theme of t...

The aim of this study is to compare the microhardness five different bulk fill composites (SDR, TEC, XTF, SF, FBF). A total 25 cylindrical molds were prepared. Composite resin was placed in each mold sequence, at one time, by condensing it thoroughly. Then, polymerization achieved with LED light device which applied for 20 seconds. Microhardness measurements samples made classical Vicker's test...

Montmorillonite KSF has been used as an effective and non-toxic heterogeneous catalyst for one-pot synthesis of 5-substituted 1H-tetrazoles via [3+2] cycloaddition of sodium azide with a wide variety of nitriles. The reaction afforded high yields of the desired products in a short reaction time under mild reaction conditions. The catalyst can be recovered by simple filtration and reuse...

We synthesized 16 novel red-emitting Mn(IV)-substituted phosphors of the compositions MgGeF6 : Mn, MgPbF6 CaMF6 Mn (M=Ge, Sn, Pb, Zr, Hf), SrSnF6 “SrTiF6 Mn”, BaPbF6 ZnMF6 (M=Sn, and CdMF6 (M=Pb, Hf) using a dry-chemical fluorination process completely avoiding hydrofluoric acid. In comparison with commonly used red-emitter K2SiF6 (KSF) its emission maximum at 630.8 nm, all above Ca Sr compound...
