Method for Determining Crystal Grain Size by X‐Ray Diffraction
, 2018 The crystal grain size can be quantitatively calculated by Scherrer equation according to the diffraction peak broadening in the XRD curves. Actually, the results calculated by the Scherrer equation are the thickness that perpendicular to the crystal ...

Advanced Engineering Materials, EarlyView.The microstructure of Cr‐rich Cr‐Si‐alloys is maintained by alloying with Ge, Pt, and Mo. The effects of these elements on A15‐phase fraction, partitioning, microstructural stability, grain size, and hardness are combinable. Molybdenum is found to be the most promising alloying element for microstructural stability during high‐temperature exposure.

Cholesteryl esters of saturated fatty acids: cosolubility and fractionation of binary mixtures
Journal of Lipid Research, 1987 Factors affecting the solid state miscibility of saturated chain cholesteryl esters were determined from electron diffraction and differential scanning calorimetric measurements on a homologous series which included two types of crystal packing. Electron

Predictions for pp single diffractive cross section at LHC [PDF]
arXiv, 2012 A model based on Gribov's Regge calculus was developed [1] and was proposed to describe diffractive processes. In this note we present numerical vales obtained from [1] for the dependence of single diffraction cross-section on diffractive mass at $\sqrt{s}$ = 0.9, 2.76 and 7 TeV.

Correlations in interference and diffraction [PDF]
, 1997 Quantum formalism of Fraunhofer diffraction is obtained. The state of the diffraction optical field is connected with the state of the incident optical field by a diffraction factor. Based on this formalism, correlations of the diffraction modes are calculated with different kinds of incident optical fields.

, 2022 AbstractTowards the end of the editing process, we started to see the book as something more than a collection of chapters around a theme: as an assemblage, which included, of course, the community of authors. When we put out the first call for contributions in May 2018, most authors volunteered a contribution rather quickly, others joined a bit later,

Advanced Engineering Materials, EarlyView.Additive manufacturing is a promising route for the production of Ni‐base superalloys for turbine applications, such as Inconel 718. Nonetheless, it induces various changes in the microstructure and performance of these materials. One such change is the incidence of the δ‐Ni3Nb phase, whose impact on microstructure, aging precipitate fractions, and ...

Applied Sciences, 2018 Optical tweezers can manipulate micro-particles, which have been widely used in various applications. Here, we experimentally demonstrate that optical tweezers can assemble the micro-particles to form stable structures at the glass–solution interface in ...

Exact paraxial diffraction theory for polygonal apertures under Gaussian illumination [PDF]
arXiv, 2019 Paraxial diffraction of monochromatic Gaussian beams by arbitrarily shaped polygonal apertures is analytically explored within the boundary diffraction wave theory framework. Exact closed-form expressions of the diffracted wavefield are obtained, as well as an interesting connection between classical optics and probability theory.

X-ray Diffraction and the Identification and Analysis of Clay Minerals
, 1990 standard thermodynamic treatments lead to the energetics of transfornaations involving both Fe and Mn and to the concept of stability diagrams. This is followed by a consideration of the solubility of iron oxides from the perspective of a 'standard state'
