attempts have been made for the first time to produce a friction material with thermal sensitive modulus by the inclusion of combined plastic/rubber properties of thermoplastic elastomers (tpe) as viscoelastic polymeric materials into the formulation for the purpose of increasing the damping behavior. in order to evaluate the viscoelastic parameters such as loss factor (tan δ) and elastic modul...

Materials Butyllithium solution in hexane (1.6 M) and molybdenum disulfide (MoS2, 99.0% purity) with an average diameter of about 1 μm were purchased from Aladdin. Nitrile rubber (NBR) with acrylonitrile content 40%, was manufactured by Jilin Chemical Industry Company, Jilin, China. 1butyl-3-methyimidazolium chloride ionic liquid was supplied by Henan Lihua pharmaceutical Co., Ltd. The chemical...

Agricultural workers rely on chemically protective gloves for protection from dermal exposure to insecticides. In Australia the most widely used gloves are manufactured from polyvinyl chloride or nitrile butadiene rubber. During insecticide application splashes and spills frequently occur on the external surfaces of gloves which may compromise the integrity of the membrane. Interaction of two o...

Nitrile N-oxides are useful reagents and crosslinkers for catalyst- byproduct-free 1,3-dipolar cycloaddition reactions. The stability of nitrile can be enhanced by introducing bulky substituents, whereas their reactivity decreases concomitantly. Herein, an isolatable aliphatic ditopic N-oxide was synthesized applied to catalyst-free crosslinking unsaturated bond-containing polymers. By decreasi...

A 68-year-old non-atopic woman was referred with recurrent perioral and lip dermatitis and oedema of the oral mucosa following dental treatments. Prior to retirement, she had been working as an auxiliary nurse for 31 years. Throughout a normal workday, she had been using protective rubber gloves for more than 2h in total, and >20 pairs of protective gloves. At the time, she experienced fluctuat...
