Laser fragmentation of Al nanoparticles in liquid isopropanol is experimentally studied. Nanoparticles are characterized by Transmission Electron Microscopy and measuring disk centrifuge. As the result, size reduced from more than 100 nm down to 10 nm. These considered as additives hydrocarbon fuels.

Titanium diboride is one of the candidate materials for high temperature applications and also for control rod elements in high temperature reactors. This paper presents the experimental data on the composites of B4 C-nano TiB2 that were synthesized successfully by co-precipitation methodat 1523K. Titanium tetraisopropanol, boron carbide, isopropanol and triton x-100were used as the precursor m...

RATIONALE Hemoglobin Hornchurch is regarded as an asymptomatic hemoglobinopathy with no obvious hematological or clinical abnormalities. Recently, we identified hemoglobin Hornchurch in a 13-year-old Chinese boy complicated with thrombocytopenia, which displayed instability in isopropanol precipitation test. PATIENT CONCERNS In this case report, we reported a Chinese boy with hemoglobin Hornc...

Acetonitrile is a choice of solvent for almost all chromatographic separations. In recent years, researchers around the globe have faced an acetonitrile shortage that affected routine analytical operations. Researchers have tried to counter this shortage by applying many innovative solutions, including using ultra performance liquid chromatography (UPLC) columns that are shorter and smaller in ...

Field emission properties of carbon black, carbon black and silica, and diesel engine exhaust were investigated and compared to multiwall carbon nanotubes prepared in a similar manner. Sample preparation consisted of pressing the nanopowders into pellet form, dispersing them in isopropanol, or dispersing them in Shipley S1818 photoresist to achieve better adhesion to the substrates. Turn-on fie...

Consequences of loading level of ceria (5, 10 and 20-wt%) on the structural, textural and surface acid-base properties as well as the impacts on catalytic activity towards isopropanol decomposition on pure and phosphated alumina is described. The obtained results indicated that composites mainly kept γ-alumina structure and the addition of ceria and/or phosphate has no effect on the bulk struct...

A dielectric barrier discharge reactor with inner electrode modified with metal oxides of Ti, Mn and Co has been designed and tested for the oxidation of diluted volatile organic compounds (VOCs) of different nature like toluene, isopropanol and trichloroethylene. It has been observed that at a fixed concentration of VOC, total oxidation of isopropanol is achieved at lower specific input energy...

Effective skin antisepsis is of central importance in the prevention of wound infections, colonization of medical devices, and nosocomial transmission of microorganisms. Current antiseptics have a suboptimal efficacy resulting in substantial infectious morbidity, mortality, and increased health care costs. Here, we introduce an in vitro method for antiseptic testing and a novel alcohol-based an...

The SLD drift chamber requires a ‘slow’ drifting gas and low diffusion to allow wave form digitization. CO2 provides this but requires an admixture of a quencher to provide more gain. _ A test chamber with an 8 sense wire cell, such as will appear in the final chamber, was exposed to an X-ray tube while containing a variety of binary admixtures of COz: 8% isobutane, 8% ethane, and 2% isopropano...
