Using their novel approach, ULA-SNOM, the researchers managed to reduce the movement of the scanning tip to an incredibly tiny level. In this method, the tip oscillates with an amplitude of only 0.5 ...

Scientists use scanning tunneling microscopy to understand how a material's electronic or magnetic properties relate to its ...

High power, high frequency vacuum electronic devices require high brightness, low emittance electron beams to operate [1]. To meet these demands, thermionic cathodes encounter challenges with rapid ...

Some mushrooms are sturdier than others, but it isn’t necessarily because of their chemistry – it’s how the filaments that ...

A new report says the withdrawal of U.S. funding has caused a “systemic shock” to the global effort against AIDS and HIV.

A new report by the U.N. AIDS agency says the sudden withdrawal of U.S. funding has caused a “systemic shock” to the global ...

Due to the lack of objectivity of electron microscope focusing in traditional manual focusing, resulting in inaccurate image focusing, this paper proposes a high-precision focusing method for electron ...
