A Scanning Electron Microscope for Ultracold Atoms

open access: yes, 2006
We propose a new technique for the detection of single atoms in ultracold quantum gases. The technique is based on scanning electron microscopy and employs the electron impact ionization of trapped atoms with a focussed electron probe.

Chondrogenic potential of canine articular cartilage derived cells (cACCs)

open access: yesOpen Life Sciences, 2016
In the present paper, the potential of canine articular cartilage-derived cells (cACCs) for chondrogenic differentiation was evaluated. The effectiveness of cACCs’ lineage commitment was analyzed after 14 days of culture in chondorgenic and non ...

Multicolour correlative imaging using phosphor probes [PDF]

open access: yes, 2015
Correlative light and electron microscopy exploits the advantages of optical methods, such as multicolour probes and their use in hydrated live biological samples, to locate functional units, which are then correlated with structural details that can be ...

Application of Electromyography Technology to Predict Chronic Diseases for COVID-19 Patients

open access: yesFrontiers in Biomedical Technologies
Purpose: Electromyography (EMG) is widely used to measure grip strength to evaluate neuromuscular activity, and thus it is possible to predict the health status of the heart muscle of those infected with the Coronavirus (COVID-19) and the extent of its ...

Ultrafast supercontinuum fiber-laser based pump-probe scanning MOKE microscope for the investigation of electron spin dynamics in semiconductors at cryogenic temperatures with picosecond time and micrometer spatial resolution

open access: yes, 2013
We describe a two-color pump-probe scanning magneto-optical Kerr effect (MOKE) microscope which we have developed to investigate electron spin phenomena in semiconductors at cryogenic temperatures with picosecond time and micrometer spatial resolution ...
