Deposition of carbon nanotubes in commonly used sample filter media

There is no single standard technique or methodology to characterize the size, structure, number, and chemical composition of airborne carbon nanotubes.  Existing analytical instruments and analytical techniques for evaluating nanoparticle concentrations cannot simultaneously provide morphology, state of agglomeration, surface area, mass, size distribution and chemical composition data critical...

Electrophilicity and nucleophilicity of commonly used aldehydes.

The present approach for determining the electrophilicity (E) and nucleophilicity (N) of aldehydes includes a kinetic study of KMNO4 oxidation and NaBH4 reduction of aldehydes. A transition state analysis of the KMNO4 promoted aldehyde oxidation reaction has been performed, which shows a very good correlation with experimental results. The validity of the experimental method has been tested usi...

Toxicological Assessment of Commonly Used Plastics

Plastic materials are commonly used for storing food stuffs and medicines. Chemical substances used in the manufacture of plastic goods are found to migrate in the food stuffs used. The migration of UV absorbents and oxidisable matter was found to be more when used for longer periods.
