In the present work, dissimilar joints between C45 carbon steel and nickel-chromium 16NiCr6 rods were produced using rotary friction welding process. Statistical analysis based on response surface methodology (RSM), microstructural examination scanning electron microscopy with backscattered diffraction (EBSD) mechanical tests performed to investigate weld joints. The results showed that time ro...

AIM The aim of this study was to measure the increase in root canal surface area and canal transportation after biomechanical preparation at 1, 3, and 5 mm short of the apex with three different rotary systems in both continuous rotary and reciprocating rotary motions. MATERIALS AND METHODS Sixty freshly extracted human mandibular molars with mesial root canal curvatures between 20° and 30° w...

The unidirectional rotation of chemically crosslinked light-driven molecular motors is shown to progressively shift the swelling equilibrium hydrogels. concentration and initial strand density polymer network are key parameters modulate macroscopic contraction material, both can be tuned using chains different weights. These findings led design optimized hydrogels revealing a half-time approxim...
