Calculus migration is a common problem during ureteroscopic laser lithotripsy procedure to treat urolithiasis. A conventional experimental method to characterize calculus migration utilized a hosting container (e.g., a “V” grove or a test tube).

Laser-tissue vaporization through a fiber catheter is evolving into a major category of surgical operations to remove diseased tissue. Currently, during a surgery, the surgeon still relies on personal experience to optimize surgical techniques. Monit

Vaporization and coagulation are two fundamental processes that can be performed during laser-tissue ablation. We demonstrated a method allowing quasi-dynamically observing of the cross-sectional images of tissue response during ablation. The results

Hard disks with different roughness levels have been coated with hydrogenated and/or nitrogenated carbon using magnetron sputtering and plasma beam based carbon guns. The plasma beam is generated by means of the self bias effect of an asymmetric, mag

The morphology and porosity of thin chromium films are greatly influenced by the mobility of the adatoms on the growing film surface, which is controlled by substrate temperature, substrate bias during sputter deposition, and sputter pressure. Cr fil

In this study, the characteristics of two relatively fast pore decoration techniques used for studying corrosion susceptibility of thin film disks with the structure CoCrTa/Cr/NiP/AlMg are discussed. The first technique employs HCl vapor. Since the H

Thin nitrogenated carbon overcoats were deposited on magnetic rigid disks by unbalanced DC‐magnetron sputtering using a mixture of argon and nitrogen gases. Nitrogen content of nitrogenated carbon is important in determining its tribological perfor

Protective wear coatings for disks that incorporate a layer of nitrogenated carbon (CN X ) have recently attracted attention. The thickness and nitrogen content of such a layer affects the electrical resistivity, mechanical wear behavior, as well as
