Controlled shrinkage and re-expansion of a single aqueous droplet inside an optical vortex trap

Article Abstract:

The shrinkage and re-expansion of individual femtoliter-volume aqueous droplets are described that are suspended in an organic medium and held in an optical vortex trap. A heat and mass transfer model is constructed to elucidate the mechanism behind this phenomenon and experimental verifications are carried out for this model.

Ewald ionic maps gauging the effect of solvent interaction on crystal morphology illustrated by surface X-ray diffraction of potassium dihydrogen phosphate

Article Abstract:

It has been possible to identify criteria encouraging a correct interpretation of surface X-ray diffraction data, and thus the effect of the solvent on the surface structure and growth morphology of ionic compounds. These criteria include completeness of the employed set of theoretically valid trial solutions.
