Analytical Tem Characterisation of Catalytic Materials

The application of analytical transmission electron microscopy in characterisations of catalytic materials is presented by studying the mechanically activated vanadium pentoxide V2O5. Local morphology and lattice distortion are studied by TEM while the oxidation states are determined by EELS. The mechanical activation can be described as a two -stage process: crushing of large crystals into sma...

Hyphenated Techniques in Gas Chromatography

Hyphenated gas chromatography (GC) (Chaturvedi & Nanda, 2010; Coleman III & Gordon, 2006) mainly refers to the coupling of the high-performance separation technique of gas chromatography with 1) information-rich and sophisticated GC detectors which otherwise can be mostly operated as a stand-alone instrument for chemical analysis, and 2) automated online sample preparation systems. The term “hy...

Screening for Triterpenoid Saponins in Plants Using Hyphenated Analytical Platforms.

Recently the number of studies investigating triterpenoid saponins has drastically increased due to their diverse and potentially attractive biological activities. Currently the literature contains chemical structures of few hundreds of triterpenoid saponins of plant and animal origin. Triterpenoid saponins consist of a triterpene aglycone with one or more sugar moieties attached to it. However...

NUMERICAL TECHNIQUES FOR DIFFERENT THERMAL INSULATION MATERIALS

The objective of this work is to predict the temperature of the different types of walls which are Ferro cement wall, reinforced cement concrete (RCC) wall and two types of cavity walls (combined RCC with Ferrocement and combined two Ferro cement walls) with the help of mathematical modeling. The property of low thermal transmission of small air gap between the constituents of combine materials...

Hyphenated Techniques in Environmental Speciation Analysis

The recognition of the fact that the chemical, biological and toxicological properties of an element are critically dependent on the form in which the element occurs in the sample has spurred a rapid development of an area of analytical chemistry referred to as speciation analysis [1]. A fundamental tool used for speciation studies is the combination of a chromatographic separation technique, t...
