In Situ/Operando Electrocatalyst Characterization by X-ray Absorption Spectroscopy

Chemical Reviews, 2020
During the last decades, X-ray absorption spectroscopy (XAS) has become an indispensable method for probing the structure and composition of heterogeneous catalysts, revealing the nature of the active sites and establishing links between structural ...

X-RAYS AND X-RAY DIAGNOSIS. [PDF]

JAMA: The Journal of the American Medical Association, 1897
A great discovery, great in the sense of discovering a fundamental principle or a fact profoundly modifying existing theories or hypotheses, is not infrequently found to be of most value, from the purely utilitarian standpoint, in some branch of science, or some art, other than that in which it was primarily made.

BAT X-ray Survey - III: X-ray Spectra and Statistical Properties [PDF]

, 2007
In this concluding part of the series of three papers dedicated to the Swift/BAT hard X-ray survey (BXS), we focus on the X-ray spectral analysis and statistical properties of the source sample.

X-Ray Binaries [PDF]

, 2016
This chapter discusses the implications of X-ray binaries on our knowledge of Type Ibc and Type II supernovae. X-ray binaries contain accreting neutron stars and stellar--mass black holes which are the end points of massive star evolution. Studying these remnants thus provides clues to understanding the evolutionary processes that lead to their ...

A variable near-infrared counterpart to the neutron-star low-mass X-ray binary 4U 1705-440 [PDF]

, 2008
We report the discovery of a near-infrared (nIR) counterpart to the persistent neutron-star low-mass X-ray binary 4U 1705-440, at a location consistent with its recently determined Chandra X-ray position.

Visualization of internal 3D structure of small live seed on germination by laboratory-based X-ray microscopy with phase contrast computed tomography

Plant Methods, 2020
Background The visualization of internal 3D-structure of tissues at micron resolutions without staining by contrast reagents is desirable in plant researches, and it can be achieved by an X-ray computed tomography (CT) with a phase-retrieval technique ...

X-ray bursts [PDF]

International Astronomical Union Colloquium, 1993
An X-ray burst is a sudden increase (rise time of order seconds) of the X-ray brightness of an X-ray source, which after reaching its peak decays, generally within a minute. The sky distribution of X-ray burst sources indicates that they are galactic objects (see Fig.

Magnetar-like X-ray Bursts from an Anomalous X-ray Pulsar [PDF]

, 2002
Anomalous X-ray Pulsars (AXPs) are a class of rare X-ray pulsars whose energy source has been perplexing for some 20 years. Unlike other, better understood X-ray pulsars, AXPs cannot be powered by rotation or by accretion from a binary companion, hence ...
