Micromechanical behaviors related to confined deformation in pure titanium [PDF]

open access: yesMATEC Web of Conferences, 2020
Confined deformation, e.g. mechanical twinning, shear banding, and Lüders banding, etc. was extensively observed in metals and alloys with low stacking-fault energies, especially under complex loadings, governing the mechanical properties.

Retrieving Tarnished Daguerreotype Content Using X-ray Fluorescence Imaging—Recent Observations on the Effect of Chemical and Electrochemical Cleaning Methods

open access: yesHeritage, 2021
We report a study on the effect of chemical and electrochemical cleaning of tarnished daguerreotypes observed using X-ray fluorescence (XRF) microscopy with a micro-focussed X-ray beam from a synchrotron source.

Investigate the Function and Structure of (Fe,Cr) La2Ti2O7 Photocatalyst Calcined under the Nitrogen Atmosphere

open access: yesBulletin of Chemical Reaction Engineering & Catalysis, 2023
Extensive research has been conducted on enhancing the photocatalytic activity of Lanthanum titanium oxide (La2Ti2O7) based photocatalysts. However, these photocatalysts were found to be inactive under visible light.

Synchrotron X-ray Analysis of the Influence of the Magnesium Content on the Absorptance during Full-Penetration Laser Welding of Aluminum

open access: yesMetals, 2021
Full-penetration laser beam welding is characterized by a weld seam whose depth equals the material thickness. It is associated with a stable capillary and is therefore widely used for welding of sheet metal components.

Noncommutative synchrotron [PDF]

open access: yesPhysical Review D, 2004
We study the departures from the classical synchrotron radiation due to noncommutativity of coordinates. We find that these departures are significant, but do not give tight bounds on the magnitude of the noncommutative parameter. On the other hand, these results could be used in future investigations in this direction. We also find an acausal behavior

A new satellite of manganese revealed by extended-range high-energy-resolution fluorescence detection

open access: yesJournal of Synchrotron Radiation, 2023
The discovery of a new physical process in manganese metal is reported. This process will also be present for all manganese-containing materials in condensed matter.

Synthesis and electrical properties of BaBiO3 and high resistivity BaTiO3–BaBiO3 ceramics [PDF]

open access: yesJournal of Advanced Dielectrics, 2016
Ceramics of the composition BaBiO3 (BB) were sintered in oxygen to obtain a single phase with monoclinic I2/m symmetry as suggested by high-resolution X-ray diffraction.

PEROVSKITES AND OTHER FRAMEWORK STRUCTURE CRYSTALLINE MATERIALS (BOOK' FIRST PAGES AND PREFACE)

open access: yesMaterials and Devices, 2021
Perovskites are among the most famous materials due to their exceptional properties: they present nearly all existing types of interesting properties, in particular as ferroics or multiferroics, they may be insulators, (super)conductors, or ...
