Addition of acid in SIMS.

Contractive maps in Mustafa-Sims metric spaces

The xed point result in Mustafa-Sims metrical structures obtained by Karapinar and Agarwal[Fixed Point Th. Appl., 2013, 2013:154] is deductible from a corresponding one stated in terms ofanticipative contractions over the associated (standard) metric space.

TOF-SIMS in Cosmochemistry

Time-of-flight secondary ion mass spectrometry (TOF-SIMS) was introduced into cosmochemistry about a decade ago. Major advantages of TOF-SIMS compared to other ion microprobe techniques are (a) parallel detection of all secondary ions with one polarity in a single measurement – both polarities in subsequent analyses, (b) high lateral resolution, (c) sufficient mass resolution for separation of ...

Michael addition of Pyrrole and indole to α,β- unsaturated compounds in the Presence of oxalic acid

A Simple and efficient method for Michael addition of pyrrole and indole to α,β- un saturated compounds has been developed in the presence of oxalic acid under refluxing reaction condition was achieved.

Applications of TOF-SIMS in Planetology

In planetology the analysis of micrometer-sized samples like, e.g., inclusions in meteorites, interplanetary dust, and presolar grains has become more and more important. This requires techniques with high lateral resolution, no or little sample destruction, and high sensitivity. To still obtain unbiased information on this kind of samples a technique or a suite of techniques has to be selected...
