An Anomalous Contrast of Insulators in Scanning Electron Microscope: The Split Image [PDF]
arXiv, 2016 A novel phenomenon of anomalous contrast in scanning electron microscope when the instrument is used to observe an insulator specimen with a wolfram probe, we called double imaging, is reported in this article. We give a detail analysis of this phenomenon in its occurrence, and discuss the influence of the added probe to internal electric field which ...

Spherical aberration correction in a scanning transmission electron microscope using a sculpted foil [PDF]
, 2017 Nearly twenty years ago, following a sixty year struggle, scientists succeeded in correcting the bane of electron lenses, spherical aberration, using electromagnetic aberration correction. However, such correctors necessitate re-engineering of the electron column, additional space, a power supply, water cooling, and other requirements.

Advanced Engineering Materials, EarlyView.A novel approach for alloy development in laser powder bed fusion is introduced. Instead of producing massive samples of one composition at a time, prepressed powder bed samples produced from powder mixtures are processed. Guidelines for the selection of precursor powders are developed.

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 ResearchIntroduction: 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.

Imaging of native early embryogenic tissue of Scots pine (Pinus sylvestris L.) by ESEM
Open Life Sciences, 2015 Environmental scanning electron microscopy enables the investigation of uncoated pine early embryogenic tissue samples in situ. The samples were examined under low vacuum conditions (air pressure 550 Pa) at a temperature of around -18°C by the AQUASEM II

Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed FeCr(Si)N Stainless Steel
Advanced Engineering Materials, EarlyView.The alloying element Nitrogen enhances stainless steel strength, corrosion resistance, and stabilizes austenite. This study develops austenitic FeCr(Si)N steel production via powder metallurgy. Fe20Cr and Si3N4 are hot isostatically pressed, creating an austenitic microstructure.
