Microencapsulated phase-change materials(MPCMs) were prepared by means of in-situ polymerization,with melamine-formaldehyde as the shell and n-octadecane as the core.The properties of the products were then ana-lyzed and characterized by using optic microscope,SEM and DSC,and the effects of the ...
In addition to mechanical pre-treatments a removal of material at the cutting edge can also be achieved by plasma-based etching processes. Usually, ion etching (IE) is used to clean and condition the substrate surface prior to the deposition of the coatings in order to improve the adhesion of...

The surfaces of prepared samples were investigated by field emission scanning electron microscope (SEM). In addition, surface area and pore size, as well as particle size distribution of the prepared samples, were measured using nitrogen absorption isotherm and dynamic laser light scattering, ...
Microcapsules were prepared by in situ polymerization of urea–formaldehyde resin to form shell over linseed oil droplets. Characteristics of these capsules were studied by FTIR, TGA/DSC, scanning electron microscope (SEM) and particle size analyzer. Mechanical stability was determined by stirring ...
Ionic liquids (ILs) are a broad group of organic salts of varying structure and properties, used in energy conversion and storage, chemical analysis, separation processes, as well as in the preparation of particles in nano- and microscale. In material engineering, ionic liquids are applied to sy...
