this study aimed to evaluate enamel roughness after adhesive removal using different burs and an er:yag laser.the buccal surfaces of forty human premolars were sealed by two layers of nail varnish, except for a circular area of 3 mm in diameter on the middle third. the enamel surfaces were initially subjected to profilometry analysis and four parameters of surface irregularity (ra, rq, rt and r...

All-solid-state batteries have emerged as promising alternatives to conventional Li-ion owing their higher energy density and safety, which stem from use of inorganic solid-state electrolytes instead flammable organic liquid electrolytes. Among various candidates, sulfide are particularly for the development high-energy all-solid-state Li metal because high ionic conductivity deformability. How...
