Supramolecular Chiral Assembly of Open‐Shell Quinoids With Chiral Additives and Their Spin‐Dependent Transport in Magneto Field‐Effect Transistors

Small, EarlyView.
Open‐shell quinoids with intrinsic spins are assembled into chiral supramolecular structures via blending with chiral additives. Thermal annealing induces stable co‐crystallization, leading to a 30‐fold amplification of chirality (gabs = 1.23 × 10−2). Significantly, this study represents the first integration of spin‐possessing chiral assemblies into ...

Assessment of Different Technologies in the Fabrication of 3D Printed Tooth Models for Dental Education

European Journal of Dental Education, EarlyView.
ABSTRACT Background 3D printing has emerged as a practical method for fabricating customisable, accurate and affordable dental training models. Numerous 3D printing technologies exist, though there is no standardised comparison to inform their implementation in dental education.

Effect of Flash Light Sintering on Silver Nanowire Electrode Networks

, 2020
We investigated the flash light sintering process to effectively reduce electrical resistance in silver nanowire networks. The optimum condition of the flash light sintering process reduces the electrical resistance by ~20%, while the effect of the ...

Bond strength and interfacial analysis of six CoCr alloys made by conventional casting and selective laser melting

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effects of the elemental composition and the manufacturing process of cobalt chromium–molybdenum (CoCr–Mo), cobalt chromium–tungsten (CoCr–W), and CoCr–Mo‐W alloys on metal–ceramic bond strength. Materials and Methods Six CoCr‐based alloys were included in this study, a were classified into three different groups ...

Influence of the post‐processing protocol on a biocompatible 3D‐printed resin

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the cytotoxicity of a biocompatible 3D‐printed resin material for occlusal devices after post‐processing with two different high‐intensity UV‐polymerization devices and two rinsing solvents, in the presence of human gingival fibroblasts (HGFs).
