Recent high-resolution infrared space missions have revealed supernova remnants (SNRs) of diverse morphology in infrared (IR) dust emission that is often very different from their X-ray appearance. The observed range of infrared-to-X-ray (IRX) flux ratios of SNRs are also wide. For a sample...
Combining label-free super-resolution microspectroscopy for sub-cellular imaging based on novel optical photothermal infrared (O-PTIR) and synchrotron-based X-ray fluorescence (S-XRF) nano-imaging techniques, we capture elemental distribution and fibrillary forms of amyloid-β proteins in the same ...
From X-ray powder patterns, the existence of a superstructure has been detected in α-RuCl3, and the structure of β-RuCl3 has been found to be of the β-TiCl3 type with linear chains of ruthenium atoms lying in distorted octahedra of chlorine atoms. The infrared spectra have been ...
However, there currently exists a strong drive towards obtaining a synchrotron X-ray facility on the African continent and the purpose of this critical and timeous review is thus to highlight the importance of such equipment for the local earth science community (e.g., geologists, geochemists ...
Constraining this absorption, which is due to γ-ray pair production on diffuse radiation, provides an important constraint on the infrared extragalactic background intensity. Without the intrinsic spectrum, we show that detecting absorption is very difficult and argue that Mrk 421 and Mrk 501, as ...
Deep Infrared Observations of the Puzzling Central X-Ray Source in RCW 103* ** 1E 161348-5055 (1E 1613) is a point-like, soft X-ray source originally identified as a radio-quiet, isolated neutron star, shining at the center of the 200... AD Luca,RP Mignani,S Zaggia,... - IOP ...
Pixel-level multi-spectral image fusion (PLMSIF) of X-ray, visible and infrared is highly desired in various areas such as medical imaging9, security monitoring10and nondestructive testing11. As for application in medical imaging, the X-ray image emphasizes the inorganic skeleton texture, while ...
3.7.X-RAY ABSORPTION FINE STRUCTURE (NEXAFS, XANES) The absorption of X-rays close to theabsorption edgeof an element occurs as a multiple scattering process and hence carries information not only about theredox stateof an atom but also about the type and symmetry of its coordination sphere al...
In general, the axial resolution is jointly determined by the X-ray pulse width and detection bandwidth of the ultrasonic transducer. In our experiments, a 2.25 MHz ultrasound transducer was used, which determined the imaging resolution with R = 0.88 vs /fmax of about 0.30 mm14...
The dynamics of liquid water feature a variety of time scales, ranging from extremely fast ballistic-like thermal motion, to slower molecular diffusion and hydrogen-bond rearrangements. Here, we utilize coherent X-ray pulses to investigate the sub-100
