Biodiesel is an attractive alternative fuel because of its nontoxicity and biodegradability properties. Biodiesel is produced through transesterification of vegetable oils’ triglyceride. It is obtained from vegetable oils or fats either by chemical or enzyme-catalyzed transesterification with methanol or ethanol. By using whole-cell biocatalyst immobilized within biomass support particles (BSPs...

Airborne clay mineral particles have long atmospheric lifetimes due to their relatively small size. To assess their impact on trace atmospheric gases, we investigated heterogeneous reactions on prototype clay minerals. Diffuse reflectance infrared spectroscopy identified surface-adsorbed products formed from the uptake of gaseous nitric acid and nitrogen dioxide on kaolinite and pyrophyllite. F...

No. DiMa0147 Structure of a Functionalized Oxacarbocyanine / Saponite Clay Nanofilm E. DiMasi (BNL), R. Ras and R. Schoonheydt (K. Univ. Leuven, BELGIUM) Beamline(s): X22A Introduction: Nanoscale functionalized organic films are of technological importance, for example in the case of dye molecules, where assembly into well ordered thin films produces desirable optical properties for miniaturize...

a suitable option for manufacture of packing materials is the use of clay and silver nano particles. these materials help create optimal relative impermeable quality, in addition to other features being improved. moisture-packed bread by use of these materials prevent water vapor loss and therefore reduce the level of bread becoming stale. in this study, seven types of nano-films with different...

Due to the peculiarity of spring domain strata in Jinan, phenomenon serious water seepage appears process excavation. The macro permeability soil is closely correlated with its microstructure. In this study, using X-ray micro-tomography (micro-CT) system and a self-designed device, internal pore structure Jinan red clay flow inside sample under different stages were observed. microstructure pha...

That particles are of less than 100nm in diameter called nano particles (NPS) and there are in the world naturally like volcanic activity. In the present investigation a new mixed halomercurate nano particle compound was synthesised and characterized. Triphenylphosphonium trichloromercorate (II) [P(C6H5)3H]+[HgCl3]- nanoparticle was synthesi -zed by using triphenylphosphonium chloride reaction ...

in this study, a feasible green method for the synthesis of copper oxide nanocrystalline is described by using sour cherry juice which has a significant effect on crystalline size, and morphology. the benefits of the green method, not only nanometer scale are formed but also low-cost method are obtained in a normal atmosphere which it has been used (ch3coo)2cu.h2o individually as cu sources. al...

nano-hydroxyapatite/gelatin (nha/ge) microspheres are currently used in bone tissue engineering as bone filler. in this  study, the effect of fabrication process parameters on the particle size of nano-hydroxyapatite/gelatinmicrospheres was investigated. the nha/ge microspheres were fabricated using water in oil emulsion. in order to design an experimental design, a surface response model with ...
