In your view, which current SEM is most recommended for EBSD/TKD and EDS analysis?

I know that this is a very difficult question, as the areas of application can vary greatly. However, if you want to operate low as well as high resolution (from a few millimeters to nanometers),...

Is a tetrahedron uniquely defined if all length of one triangle and all three angles between the edges of the opposite corner are known?

Known are the length in a triangle ABC of a tetrahedron ABCD, i.e., also all angles between A, B and C are known. The position of D is, however, unknown, but the angles between all edges to D,...

Does martensite describes a phase or a microstructure?

We are often talking about martensite, however, martensite is as far as I know never listed as phase in a database like ICSD. Asking metal physists they told me many years ago that martensite is a...

Is there any term which describes the "order of zones" like ZOLZ, FOLZ etc in reciprocal space?

Parallel planes in reciprocal lattice can be easily distinguished by terms like ZOLZ (zero order Laue zone), FOLZ (first order Laue zone) etc. Is there any therm which is equivalent in crystal...

What decides about the lattice description in Ramsdell's notation of stacking, e.g. in polytypes?

Crystal structures consisting of stacked layers can be described by Ramsdell notation. Thus, cubic-closed packed (ccp) is given by a sequence ABC....or 3C, whereas hcp (hexagonal-closed packed) is...

Anyone familiar with variable pressure SEM or HV-SEM equipped with a gas injection system?

For many years I am using an SEM (scanning electron microscope) with variable pressure (i.e. low vacuum) which dramatically helps if any kind of charging occurs. Often only a very small chamber...

Which reagent is best among 'Dimethylglyoxime" and "Dithiothreitol" for spectroscopic determination of Nickel ?

What I think is Dithiothreitol. As it is water-soluble and does not form a precipitate. But, the thing is it contains sulphur which is quite hazardous to aquatic animals.
