In the past two decades, coatings of the Ti–Al–N ternary system have attracted considerable research and industrial interest. Nevertheless, the Ti–Al–N system still offers new interesting possibilities for coating developments such as the addition of low N contents to Ti–Al films in order to reach a good compromise between high hardness and a low friction coefficient. Ti–Al–N coatings with low ...

in this study, 22 patients (15-75 years old) were selected and transferred to ct scan for tumor ablation. for ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. then, laser probe inserted through the needle and laser energy delivered. although we ...

In this study, the graphene-modified Al foils are prepared to assemble lithium ion batteries (LIBs) through a three-step approach comprising: (1) deposition of polyamic acid (PAA) on substrate; (2) curing PAA form polyimide (PI)-coated foils; (3) converting PI into porous graphene by CO2 laser irradiation. With integration derived (PDG) in LIBs, inserted PDG layer can enhance adhesion and inter...
