Dip coating consists of withdrawing a substrate from bath to coat it with thin liquid layer. This process is well understood for homogeneous fluids, but heterogeneities, such as particles dispersed in liquid, lead more complex situations. Indeed, introduce new length scale, their size, addition the thickness film. Recent studies have shown that, at first order, film monodisperse can be captured...

background: the final objective of root canal therapy is to create a hermetic seal along the length of the root canal system. for this purpose, many methods and materials have been introduced. the purpose of this study was to compare the apical microleakage in a new obturation technique (true-tug-back) with two other obturation techniques (lateral condensation and chloroform dip technique). met...

Indium tin oxide (ITO) thin films were prepared by the sol–gel dip-coating (SGDC) technique. The microstructure and electrical properties of ITO thin films crystallized using rapid thermal annealing (RTA) were compared with those of films prepared by classic thermal annealing (CTA). ITO thin films were successfully prepared by CTA at 500 jC for 30–60 min. At the same temperature of 500 jC and w...

Photosensitive films incorporating molecular photoacid generators compartmentalized within a silica-surfactant mesophase were prepared by an evaporationinduced self-assembly process. UV-exposure promoted localized acid-catalyzed siloxane condensation, enabling selective etching of unexposed regions, thereby serving as a cresistIess’ technique to prepare patterned mesoporous silica. We also demo...

Titanium (Ti) has been widely used in clinical applications for its excellent biocompatibility and mechanical properties. However, the bioinertness of the surface of Ti has motivated researchers to improve the physicochemical and biological properties of the implants through various surface modifications, such as coatings. For this purpose, we prepared a novel bioactive material, a lanthanum-in...

BACKGROUND The major hazard to the orthodontic tooth movement is the friction developing at the bracket wire interface. In the past, there have been various attempts to reduce this friction. We believe that coating the commercially available orthodontic wires with nanoparticles can result in a successful reduction of this friction. The objective of this study is to develop a novel method of coa...
