Studies on Effect of Injection Timing of Graphene Nanoparticles Blended Simarouba Biodiesel Blend on CI Engine
Graphene is a monolayer carbon atoms discovered in the recent past which has inspired researchers in a wide range of applications. It has a surface area as high as 2630 m2/g and thermal conductivity value of 3000 W/mK-1 at room temperature. It is chemically the most reactive form of carbon with one carbon atom exposed to reaction from each side. Stable dispersion of graphene was achieved using ...
متن کاملChitosan/Poly(Amide-Imide) Blend Films: Studies on Thermal and Mechanical Stability, Morphology and Biodegradability
A diacid monomer was synthesized by the condensation of L-tryptophan amino acid and pyromellitic dianhydride (PMDA). The diacid was utilized for the synthesis of three types of poly(amide-imide)s (PAIs) using three different kinds of diamines. The synthesized monomer and PAIs were characterized using FT-IR, 1H-NMR and 13C-NMR spectroscopies and the PAIs were also used ...
متن کاملstudies on properties of short fiber reinforced natural rubber composites
natural rubber/fiber composites were prepared in a laboratory mixer using new and waste short nylon fiber by a one-step mixing process. fiber loading and bonding agent effects on the microstructure and mechanical properties of the composites were studied. the cure characteristics of composites were investigated by using rheometer. cure and scorching times of the composites decreased while maxim...
متن کاملComparative Study of Butyl Rubber (IIR) and Bromobutyl Rubber (BIIR) based on FTIR, Dielectric and Thermal Studies
The study aims for a comparative study of butyl rubber (IIR) and bromobutyl rubber (BIIR) based on spectroscopic, dielectric and thermal characterization. Using FTIR, complete vibrational analysis of butyl rubber and bromobutyl rubber are made available which confirms their chemical structure and the functional groups present in them. The effect of microwave frequency, namely 10 GHz and 26 GHz ...
متن کاملStudies on Rubber (Hevea brasiliensis) Trees Exist Plant Type after Planting and Available Tapping Tree of Rubber Plantation in China
Existing plant types of rubber tree after planting and available tapping tree were investigated, and there were about 28 rubber plantations with different tapping years of 8 varieties “CATAS7-33-97”, “CATAS8-79”, “CATAS7-20-59”, “PR107”, “RRIM600”, “GT1”, “INA873”, “93-114” in South China. The results showed that there were six kinds of existing plant types of rubber tree after planting of rubb...
