Evaluation of material waste, dimensional stability, and detail reproduction of polyvinyl siloxane impression materials mixed with different mixing tips
(2021-01-01)
Statement of problem: Redesigned mixing tips, promising less impression material waste, have been marketed. However, whether their use adversely affects the dimensional stability and detail reproduction of the impression ...
Comparison of different ultrasonic tip angulations on time required for cast post removal
(2014-01-01)
Aim: The aim of this study was to design, develop and compare ultrasound tips with different angulations on time required for cast post removal. Materials and methods: To test and compare the ultrasonic tips developed, 36 ...

Dynamics of conical singularities: S type d-cones", In Instabilities and Nonequilibrium Structures VII & VIII
Conical singularities or tips of developable cones (d-cones) arising when thin sheets are subjected to large homogeneous deformations are very common but poorly understood structures. This paper reports on the nucleation ...
Scanning tunneling microscope operating as a spin diode
(Amer Physical Soc, 2011-09-19)
We theoretically investigate spin-polarized transport in a system composed of a ferromagnetic scanning-tunneling-microscope (STM) tip coupled to an adsorbed atom (adatom) on a host surface. Electrons can tunnel directly ...
AFM Imaging of Mercaptobenzoic Acid on Au(110): Submolecular Contrast with Metal Tips
(American Chemical Society, 2016-06)
A self-assembled monolayer of mercaptobenzoic acid (MBA) on Au(110) is investigated with scanning tunneling and atomic force microscopy (STM and AFM) and density functional calculations. High-resolution AFM images obtained ...
