Manipulation of nanoparticles of different shapes inside a scanning electron microscope

Beilstein Journal of Nanotechnology, 2014
In this work polyhedron-like gold and sphere-like silver nanoparticles (NPs) were manipulated on an oxidized Si substrate to study the dependence of the static friction and the contact area on the particle geometry.

In vitro evaluation of dentin tubule occlusion by three bioactive materials: A scanning electron microscopic study

Dental Research Journal, 2019
Background: Dentin hypersensitivity (DH) is a common problem characterized by a short, sharp pain. Reduction of dentin permeability by occluding dentin tubules is considered as a method for treating DH.

Vacuum‐Formed Composites Based on a Polyolefin and a High Content of Biomass‐Waste Fillers

Advanced Engineering Materials, EarlyView.
It is shown here that by the use of a very ductile polymer matrix, it is possible to vacuum‐form products that contain up to 25% of hard biofillers with still ductile properties. The results are promising and opens up for the use of engineered biocomposites derived from industrial side‐stream biofillers in vacuum‐formed products. A strategy to increase

Dentinal Tubule Occluding Efficacy of Three Nano Biomaterials Containing Toothpastes on Simulated Hypersensitive Dentin: An SEM and EDX In-vitro Analysis [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Dentin Hypersensitivity (DH) is a common dental issue characterised by sharp pain in response to stimuli. Desensitising toothpastes provide lasting relief by sealing dentinal tubules.

High‐Temperature Oxidation of the CrFeNi Medium‐Entropy Alloy

Advanced Engineering Materials, EarlyView.
The oxidation behavior of equiatomic CrFeNi MEA is a key issue that determines this material's suitability for high‐temperature application. The understanding of long‐term behavior is even more crucial than short‐term corrosion effects. The alloy is exposed to synthetic air at 1000, 1050, and 1100 °C for 24, 100, and 1000 h and systematically compared ...
