The development of lead-free solder alloys for high-temperature applications is required to meet increasing demands for reliable replacements for lead-containing alloys. This paper provides a review of recent research...

Sutureless end to end ureteral anastomoses was successfully constructed in acute and chronic experiments. A photothermal sensitive hydrolyzable (PSH) albumin stent played roles as solder and intraluminal supporter to adhesion and position the anastomosed ureter by end to end fashion. The anastomosis seam was lased with 810 nm diode laser energy supplied through hand-held 600 mm noncontact optic...
