X-ray based extensometry [PDF]
A totally new method of extensometry using an X-ray beam was proposed. The intent of the method is to provide a non-contacting technique that is immune to problems associated with density variations in gaseous environments that plague optical methods.

X-RAY FLUORESCENCE AND EMISSION | Total Reflection X-Ray Fluorescence
, 2005 Total reflection X-ray fluorescence spectrometry (TXRF) is a trace elemental micro analysis technique based on conventional energy dispersive X-ray fluorescence. It has become increasingly popular in the last few decades and is applied in almost every field of trace elemental analysis where low detection limits and multi element capabilities are ...

Holographic analysis of diffraction structure factors
, 2002 We combine the theory of inside-source/inside-detector x-ray fluorescence holography and Kossel lines/x ray standing waves in kinematic approximation to directly obtain the phases of the diffraction structure factors.

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.The ultraselective H2S detection of the ZIF‐L/SnS2 heterostructure is demonstrated. The introduction of 2‐dimensional (2D) breathable ZIF‐L results in a substantial increase in H2S selectivity attributable to the molecular sieving effect, which impedes the permeation of gases with large kinetic diameters and high polarity.

Total reflection X-ray fluorescence
Physical Sciences Reviews, 2018 Abstract Total reflection X-ray fluorescence (TXRF) spectrometry is a non-destructive and surface sensitive multi-element analytical method based on energy dispersive X-ray fluorescence spectrometry with detection limits in the lower picogram range. It utilizes the total reflection of the primary X-ray beam at or below the critical angle of incidence ...

X-ray induced persistent photoconductivity in Si-doped Al$_{0.35}$Ga$_{0.65}$As
, 2000 We demonstrate that X-ray irradiation can be used to induce an insulator-metal transition in Si-doped Al$_{0.35}$Ga$_{0.65}$As, a semiconductor with {\it DX} centers.

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the
