The synthesis, spectroscopic characterization, and fluorescence quenching efficiency of polymers and copolymers containing tetraphenylsilole or tetraphenylgermole with Si-Si, Ge-Ge, and Si-Ge backbones are reported. Poly(tetraphenyl)germole, 2, was synthesized from the reduction of dichloro(tetraphenyl)germole with 2 equivs of Li. Silole-germole alternating copolymer 3 was synthesized by coupli...

The main objective of incorporating natural fibers such as Henequen microfibers (NF) into the High Density Polyethylene (HDPE) polymer matrix is to reduce the cost and to enhance the mechanical as well as other properties. The Henequen microfibers were chopped manually to 5-7mm in length and added into the polymer matrix at the optimized concentration of 8 wt %. In order to facilitate the link ...

PURPOSE This overview presents a description of organofunctional trialkoxysilane coupling agents (silanes), their chemistry, properties, use, and some of the main clinical experiences in dentistry. MATERIALS AND METHODS The main emphasis was on major dental journals that have been reviewed from 1958 up to the latest research news from 2002. A MEDLINE search with the key words "dental silanes"...

The linear thermosensitivity of colloidal crystals immobilized in a copolymer hydrogel film composed PNIPAM and PNMAM could be enhanced by chemically binding them on glass substrate using silane coupling agent.

This research presents new insights into the utilisation of waste glass powder in concrete pavements. Two different types were used as a partial replacement for sand: 10% neat (untreated) and silane-treated powder. The interfacial bonding properties, physical mechanical properties pavement assessed at 7 28 days. Results exposed reduction 5% 2% compressive flexural strengths, respectively, an in...
