This paper describes some possibilities of using electron beam welder to machine plastics. Several different types were tested including PC, PMMA, PVC, PTFE, PE and PP. For initial study how certain material reacts to the ...
The electron beam is a tool with high energy conversion efficiency which is by and large independent of the type of metal. Its high power density qualifies the non-vacuum electron beam as an outstanding energy source for the ...
TiO2 colloid / LDHs clay nanocomposites, prepared by direct coprecipitation method, were used as photocatalysts in the reaction of (3-(4-chlorophenyl)-1,1-dimethylurea) and 4-chlorophenol decomposition in water. ...
This contribution focuses on a detailed investigation of polymerization/crosslinking process, either induced by UV radiation (λ = 365 nm), or by electron beam exposure of polypropyleneglycoldiacrylate monomers, in conjunction ...
In the paper is presented a technological cluster for mask less e-beam lithography (ML2) and metrology for fast non destructive defect inspection and review, and for CD, 2D and 3D measurement.
The cluster potentialities comply ...
In this paper the contrast and sensitivity characteristics are investigated concerning the negative tone electron beam resist HSQ (hydrogen silsesquioxane) and the positive tone SML300 electron beam organic resist, designed ...
The results of coatings properties investigations, made by electron beam and gas powder cladding process and technological demands as well, are presented in the article.
