The silicate phases of 11 pallasites were analyzed instrumentally
to determine the concentrations of some major, minor, and
trace elements. The silicate phases were found to contain about
98% olivine with 1 to 2% accessory minerals such as lawrencite,
schreibersite, troilite, chromite, and farringtonite present. The
trace element concentrations, except...
A dual -pH simultaneous direct spectrophotometric method for
the determination of calcium and magnesium using Arsenazo III has
been developed.
An absorption spectra study was made of Arsenazo III and its
magnesium, calcium, strontium, and barium complexes at various
pH values. This study showed that total calcium and magnesium
can...
The design of a novel Tabletop Role Playing Game was conducted with the aim to create a game system that provides both rigid rules and more creative outlets compared to existing games. The project focused on player-developed mystical abilities known as Spells, whereby the rule of the game guides the...
Oxides of post-transition metals often show unique structures and properties due to the presence of lone pair electrons and the diffused s orbitals. The present work focuses on synthesis and characterizations of oxides containing Te, a heavy post transition metal.
New series of pyrochlore oxides of the formula Cs(M,Te)₂O₆ (M...
An analytical technique has been developed for the determination of methylmercury compounds in environmental samples. The technique is based on a two-stage procedure. In the first stage, methylmercury compounds are isolated from the sample matrix as methylmercury chloride (MeRgCl) by distillation. The distillation procedure is based on a series of...
