Introduction: Venus is Earth’s twin in size and bulk density [1], but obviously has a very different climate and climate history. Direct comparison of their histories [2] assumes implicitly that they have similar chemical compositions and internal structures; parts of these assumptions are testable with Venera and VEGA chemical analyses of Venus’ surface. From available chemical analyses, it is...

An analysis of high-resolution VLT/UVES spectra of two B-type main sequence stars, NGC346-11 and AV304, in the Small Magellanic Cloud (SMC), has been undertaken, using the non-LTE tlusty model atmospheres to derive the stellar parameters and chemical compositions of each star. The chemical compositions of the two stars are in reasonable agreement. Moreover, our stellar analysis agrees well with...

Bio-oils from the fast pyrolysis of switchgrass forage and two sets of alfalfa stems (from two stages of developmentsbud and full flower stages) have been analyzed by wet-chemical methods, GC-MS, and HPLC. The chemical composition of bio-oil is important because it may give insights into its quality, stability, or suitability for downstream upgrading. Pyrolysis experiments were conducted at 500...

some physical properties and chemical compositions of two cultivars (semsouri and shahabadi) of cantaloupe studied during four different stages of maturity from fruit set to completely ripe. the physical properties investigated were the geometric mean diameter (gmd), specific gravity (sg), mean firmness (mf), rind, seed (%) and flesh (%). the chemical compositions were brix, titrable acidity (t...

The objectives of this experiment were to investigate the application of new ligands including different atoms & evaluation their nucleophile effects against various metals. Chemistry researchers are really interested in this field. From among various ligands, there are some ligands with different coordinating ligands as well. There are great number of intermediate complexes and major elements ...
