What is Soft X-Ray – Hard X-Ray – Definition - Radiation …
2019年12月14日 · X-rays with high photon energies (above 5–10 keV) are called hard X-rays, while those with lower energy (and longer wavelength) are called soft X-rays. Due to their penetrating ability, hard X-rays are widely used to image the inside of visually opaque objects.
Soft X-ray Tomography: Virtual Sculptures from Cell Cultures
Soft X-ray tomography (SXT) generates detailed volumetric reconstructions of cells preserved in a near-to-native, frozen-hydrated state. SXT is broadly applicable and can image specimens ranging from bacteria to large mammalian cells.
Soft X-Ray - an overview | ScienceDirect Topics
Soft X-ray full-field TXM imaging has been used to study the nanoscale structure of biological samples. It has better sample penetration than electron microscopy, facilitating 3-D tomography of cells and other samples.
One major and important subcategory of X-ray microscopy is soft X-ray microscopy based on zone plate optics, pioneered in the 1970s and 1980s and perfected over the years.
Soft X-Ray Lasers and Their Applications | Science - AAAS
1990年3月30日 · The emerging technology of soft x-ray lasers has novel applications to microscopy, lithography, and other fields. This article describes the status of soft x-ray laser research with the aim of bringing the rapid developments in this field to the attention of potential users in other disciplines.
Present indications are that X-ray microscopy will fit, as a method for structural information, between the electron microscope (atomic resolution, thin, normally dried specimens, stains essential for contrast enhancement) and the optical microscope (very flexible conditions of specimen observation, benign conditions for cells, multiplicity of o...
Soft X-rays capture the dance of the organelles
2022年2月14日 · Soft X-rays capture the dance of the organelles. A CT-like scan images what’s inside a live cell in 3D — including the interactions of its components. An X-ray-based imaging method unveils...
A guide into the world of high-resolution 3D imaging: the case of soft …
Soft X-ray tomography at cryogenic temperatures (cryoSXT) fills the imaging resolution gap between fluorescence microscopy (in the hundreds of nanometers but relatively accessible) and electron microscopy (few nanometers but requires extensive effort and can be difficult to access).
An ultrahigh-resolution soft x-ray microscope for ... - Science
2020年12月16日 · We have described a new microscope for ultrahigh-resolution coherent soft x-ray imaging at the Advanced Light Source, which provides routine access to conventional STXM and advanced imaging modes such as ptychographic microscopy with …
Soft X-ray Microscopy Techniques for Medical and Biological …
2021年8月5日 · Soft X-ray microscopy has been successfully used for investigating complex biological processes occurring at micrometric and sub-micrometric length scales and is one of the most powerful tools in medicine and the life sciences.
