Physics of Polymorphic Transitions in CeRuSn

open access: yes, 2012
We report a detailed study of the polymorphic transitions in ternary stannide CeRuSn on high quality single crystals through a combination of X-ray diffraction experiments conducted at 300, 275 and 120 K, and measurements of the thermal expansion ...

opXRD: Open Experimental Powder X‐Ray Diffraction Database

open access: yesAdvanced Intelligent Discovery, EarlyView.
We introduce the Open Experimental Powder X‐ray Diffraction Database, the largest openly accessible collection of experimental powder diffractograms, comprising over 92,000 patterns collected across diverse material classes and experimental setups. Our ongoing effort aims to guide machine learning research toward fully automated analysis of pXRD data ...

Effects of trace Ce addition on critical cooling rate and Ti (CN) precipitation of ultra high strength steel plate

open access: yesMaterials Research Express, 2020
It is well-known that issues always occur for local non-hardenability of 1.5 GPa ultra-high strength steel plates during conventional hot forming processes, once the thickness of the plates is more than 2.5 mm.

Interplay of chemical pressure and hydrogen insertion effects in $ {\bf CeRhSn} $ from first principles

open access: yes, 2008
Investigations within the local spin density functional theory (LSDF) of the intermetallic hydride system $ {\rm CeRhSnH_x} $ were carried out for discrete model compositions in the range $ 0.33 \leq x_H \leq 1.33 $.

Application of Neural Networks for Advanced Ir Spectroscopy Characterization of Ceria Catalysts Surfaces

open access: yesAdvanced Intelligent Discovery, EarlyView.
A novel convolutional neural network architecture enables rapid, unsupervised analysis of IR spectroscopic data from DRIFTS and IRRAS. By combining synthetic data generation with parallel convolutional layers and advanced regularization, the model accurately resolves spectral features of adsorbed CO, offering real‐time insights into ceria surface ...

Self-contained Kondo effect in single molecules

open access: yes, 2005
Kondo coupling of f and conduction electrons is a common feature of f-electron intermetallics. Similar effects should occur in carbon ring systems(metallocenes).

Different Roles of Ce3+ Optical Centers in Oxyorthosilicate Nanocrystals at X-ray and UV Excitation

open access: yesCrystals, 2019
Luminescence properties of Lu2SiO5:Ce3+ and Y2SiO5:Ce3+ nanocrystals were studied using photo- and X-ray luminescence techniques. The crystal structure of Re2SiO5 nanocrystals (P21/c space group) differs from the crystal structure of Re2SiO5 bulk ...

Ab initio prediction of magnetically dead layers in freestanding $\gamma$-Ce(111)

open access: yes, 2010
It is well known that the surface of nonmagnetic $\alpha$-Ce is magnetically ordered, i.e., $\gamma$-like. One then might conjecture, in agreement with previous theoretical predictions, that the $\gamma$-Ce may also exhibit at its surfaces even more ...

A Review on Magnesium Based Metal Hydrides for Thermal Energy Storage Systems

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The hydrogen storage in metal hydrides is an imminent, innovative, and environmentally beneficial approach that offers benefits for example, an ample amount of storage and elasticity in terms of thermodynamics necessary for hydrogen absorption and release.

Permian Large Igneous Provinces and Their Paleoenvironmental Effects

open access: yesGeophysical Monograph Series, Page 417-434., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
