Ultraviolet Laser-induced Oxidation of Antimony: Chemical Composition and Growth Kinetics of the Oxide Layer
The effects of UV (193 nm) laser irradiation of ant imony in the atmosphere on the kinetics of oxidation and on the oxide stoichiometry have been studied using a quartz microbalance and X-ray photoelectron spectroscopy. An absolute calibration of the quartz microbalance enables us to measure quantitatively the kinetics of the oxygen uptake on a thin film; while XPS results indicate the evolutio...
متن کاملSeasonal variation in chemical composition of the Indian mackerel (Rastrelliger kanagurta) from Karachi Coast
The chemical composition variations of the Indian mackerel (Rastrelliger kanagurta) from Karachi coast were investigated seasonally over the period of one year (2004-2005). Moisture, crude protein, fat and ash contents varied from 70.11-74.41%, 16.02- 20.09%, 3.0-12%, and 0.89-1.35% respectively. The seasonal data indicated that the main fatty acids of the total lipid were C16:0, C16:1, C18:0,...

متن کاملAssessment and comparison of surface chemical composition and oxide layer modification upon two different activation methods on a cocrmo alloy.
This study investigated the effect of two different activation methods on the surface chemical composition of a CoCrMo-alloy. The activation was performed with oxygen plasma (OP) or nitric acid (NA). The surface physical-chemical properties were thoroughly characterized by means of several analytical techniques: X-ray photoelectron spectroscopy (XPS), time-of-flight secondary ion mass spectrome...
متن کاملVariation in the chemical composition of wheat straw: the role of tissue ratio and composition
BACKGROUND Wheat straw is an attractive substrate for second generation ethanol production because it will complement and augment wheat production rather than competing with food production. However, like other sources of lignocellulosic biomass, even from a single species, it is heterogeneous in nature due to the different tissues and cell types, and this has implications for saccharification ...
