In the present work thermal-nanoimprint lithography of various commercial thermoplastic resists as matrixes for perylenediimides (PDIs) has been studied.
Ultrasound evaluation permits the state of rocks to be determined quickly and cheaply, satisfying the demands faced by today´s producers of ornamental stone, such as environmental sustainability, durability and safety of use.
“A combined experimental and numerical approach to the laser joining of hybrid Polymer – Metal parts”
A two-step method for the joining of opaque polymer to metal is presented. Firstly, the metal is structured locally on a micro-scale level, to ensure adhesion with the polymeric counterpart. In a second step, the opposite side of the micro-structured metal is irradiated by means of a laser source.
The machining response of imprinting dies when subjected to nano - second laser processing is investigated in this research.
Picosecond laser micromachining technology (PLM) has been employed as a tool for the fabrication of 3D structured substrates.
The effect of tempering after laser cladding of a high alloyed powder metallurgical tool steel was studied for die repairing purposes.
