The infrared (IR) spectrum of an adamantyl endcapped α, ω-polyyne (the hexayne, Ad-C(12)-Ad) is investigated both experimentally and computationally. A new IR band is observed upon UV photoexcitation of the compound (embedded in a poly methyl methacrylate matrix at 78 K), thus, revealing the existence of new photogenerated molecular structure trapped at low temperature. Complete reversibility i...

A modern industrial route for the manufacture of methyl methacrylate involves the reaction of methyl propanoate and formaldehyde over a silica-supported Cs catalyst. Although the process has been successfully commercialised, little is known about the surface interactions responsible for the forward chemistry. This work concentrates upon the interaction of methyl propanoate over a representative...

Synthesis of new ionic liquid methacrylates and dimethacrylates is described comprising ammonium structures various anions (bis(trifluoromethylsulfonyl)imide (NTf2), tris(pentafluoroethyl)trifluorophosphate (FAP), triflate (TFl), trifluoroacetate (TFAc)). The structure the anion has a stronger effect on both melting behavior photopolymerization kinetics compared to cation pattern. Photo-differe...

In recent years, there has been considerable research in preparing materials and finding new uses for nanoscale structures in drug delivery. Uses such as carriers for controlled and targeted drug delivery, micropatterned devices, systems for biological recognition, have shown the versatility of these biopolymeric materials [1]. We report on major new developments of recognitive drug delivery sy...

INTRODUCTION Methyl methacrylate (MMA) is commonly used in medicine and dentistry. The adverse effects of MMA are well described in the literature. Animal studies have largely confirmed the risks reported in clinical observations. There is no study indicating direct implication of MMA on male fertility mechanism. OBJECTIVES The purpose of this study was to determine whether MMA is able to mod...
