DOCUMENT TYPE: Journal CA Section: 9 (Biochemical Methods) Section cross-reference(s): 3 Nanoparticles have been widely utilized in biol. research in recent years. 1,6-Hexanedithiol was used as the medium in this work to attach Au nanoparticles on the gold plates. We studied the immobilization and hybridization of DNA probes onto the resulted plates using the quartz crystal microbalance method. Approx. 3-5 times adsorption enhancement of HS-DNA on the plates was obtained under our exptl. conditions. Using this DNA sensor, the sensitivity was promoted by approx. three times to 0.35 mg/mL.

Stabilized synthetic rubber compositions

Stabilized synthetic rubber compositions. (Sumitomo Chemical Co., Ltd., Japan). Jpn.Chemicals with cas numbers 1191-43-1 and 68092-48-8 also play role.

DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) Rubber contg. 2:1-20 mixts. of I (R = C1-4 alkyl; Z = C2-9 alkylene) and [R1S(CH2)2CO2CH2]4C (II; R1 = C4-20 alkyl) have good stability to heat and oxidn. Thus, butadiene rubber contg. 0.25 phr I (R = Me, Z = CH2CH2) [86828-12-8] (prepd. from 2,2'-methylenebis(6-tert-butyl-4-methylphenol) monoacrylate [61167-58-6] 7.95, HSCH2CH2SH [540-63-6] 0.92, and EtOH 50 g) and 0.75 phr II (R1 = C6H13) [68092-48-8] had good heat resistance and stability. .
