Electron microscopy uses a beam of electrons to illuminate a sample ... an image of the internal structure of a thin sample. Scanning electron microscopy generates a topological image of a sample.

One of the best methods for lowering air pollution is using autocatalysts, which filter harmful gases from vehicle exhaust. A ...

Object visualization may be mediated by light or electron beams ... demultiplexing with scanning a focused illumination beam over the sample. Interferometric scattering microscopy (iSCAT) is ...

But one aspect – the texture of the metals used – has been historically overlooked.

In the study, "Connectome-driven neural inventory of a complete visual system," published in Nature, researchers used focused ion beam milling and scanning electron microscopy to create a complete ...

Scientists have long noted differences between the lunar near side and far side. While the near side periodically passes ...

For the first time in history, scientists have analyzed actual samples from the lunar farside—thanks to China’s Chang’e-6 ...

Abstract: This paper presents a broadband two-dimensional (2-D) beam-scanning circularly polarized (CP) transmitarray with low sidelobe level (SLL) for millimeter-wave (mmW) applications. A ...

Researchers have developed the most powerful ultrashort electron beam to date using a novel laser shaping technique ... you have a bunch of electrons together in a focused beam.” The problem with this ...

In a paper published in National Science Review, a research team from the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, reveal differences in the near and far side lunar space ...

Abstract: For synthesizing ultra-wideband (UWB) beam-scanning aperiodic antenna arrays under mutual coupling (MC) effects, the novel constraints-reduced iterative convex optimization (CRICO) method ...
