Abstract Silane-functionalized graphene nanoplatelets (GNPs) were prepared using a newly developed approach based upon simple two-step strategy. The effect of their dispersion and interfacial bonding on the mechanical properties thermal conductivity reinforced silicone rubber (SR) was investigated. It found by Raman mapping that silane-functionalized GNPs could be dispersed uniformly into SR ma...

Child running and jumping sound are one of the major noise sources in heavy structured apartment building. It was reported that physical characteristics of rubber ball (heavy/soft impact sound) was similar with child's running and jumping. As a standard impact source, rubber ball was standardized in ISO 10140 series and ISO 16283-2. However, evaluation method of rubber ball was not proposed in ...

In this study, three types of silicone rubbers, namely, insulative rubber, conductive rubber and with as well layers are investigated for their compatibility mineral oil. Mineral oil different samples is thermally aged at 130 °C 360 h, 720 h 1080 23 °C, 98 h. At the end each ageing interval, oil-impregnated rubbers dielectric properties. Aged moisture content, breakdown voltage, colour number, ...

In this study, the dielectric properties of unfilled as well nanofilled polystyrene-silicone rubber blends are evaluated. Accordingly, preparation is carried out considering three different concentrations polystyrene (3, 7 and 10%wt). Also, nanocomposites two types nanoparticles. These nanoparticle TiO2 SiO2 with same average particle size 20 nm. Different concentration levels 1.5, 2 3%wt studi...

The dynamic behaviour of the potentiometric carbon dioxide electrode is predicted by means of a digital simulation that considers both diffusion and reaction kinetics. The method allows for complete description of the electrode response without requiring the assumption that one of these processes can be neglected. The validity of the simulation was tested experimentally by using a commercial pC...

The traction force produced by biological cells has been visualized as distortions in flexible substrata. We have utilized quantitative phase microscopy by digital holography (DH-QPM) to study the wrinkling of a silicone rubber film by motile fibroblasts. Surface deformation and the cellular traction force have been measured from phase profiles in a direct and straightforward manner. DH-QPM is ...

Brest implants made of materials such as ivory, rubber, or ox cartilage have been used since the 19th century. After the 1940s, direct subcutaneous silicone injections were introduced, which caused serious complications (infections and migration to distant tissues). In the 1960s, a solid silicone envelope filled with silicone gel or saline was used. Escape of silicone from the envelope of these...

This is a review of 20 cases of ameloblastomas diagnosed and treated at the Dental Facu ltv, University of Malaya, Kuala Lumpur. The clinical features, histological features and treatment methods are presented. Two basic clinical types namely the conventional (solid/multicystic) and unicystic ameloblastomas showed different recurrence rates. Discrepancies between the recurrent rates in this stu...
