Mixed valency in cerium oxide crystallographic phases: Determination of valence of the different cerium sites by the bond valence method [PDF]

open access: yes, 2008
We have applied the bond valence method to cerium oxides to determine the oxidation states of the Ce ion at the various site symmetries of the crystals.

Widely Tunable Angular Non-Critical Phase-Matching Wavelengths from 0.72 to 1.42 μm Based on RE1xRE21−xCOB Mixed Crystals

open access: yesCrystals, 2020
The angular non-critical phase-matching (A-NCPM) second-harmonic-generation (SHG) properties of RE1xRE21−xCOB (RE1, RE2 = Y, Gd, La, Tm, Sm, and Nd) type mixed crystals including NCPM wavelength and conversion efficiency were detailedly investigated ...

Studying the mechanical properties of (Cu1–xAgx)7GeS5I mixed crystals by using the micro-indentation method

open access: yesSemiconductor Physics, Quantum Electronics & Optoelectronics, 2018
(Cu1–xAgx)7GeS5I mixed crystals were grown using the Bridgman–Stockbarger method. The hardness dependences on the indentation depth profiles in (Cu 1–x Ag x ) 7 GeS 5 I mixed crystals were investigated.

Patterned ferrimagnetic thin films of spinel ferrites obtained directly by laser irradiation [PDF]

open access: yes, 2013
Some spinel ferrites can be oxidized or transformed at moderate temperatures. Such modifications werecarried out on thin films of mixed cobalt copper ferrites and maghemite, by heating small regions with alow-power laser spot applied for about 100 ns ...

A geometrical model for Mixed cyanide crystals

open access: yes, 1999
A model of diluted random field sustained by quenched volume deformations is shown to reproduce puzzling physical features found in X(CN)_{x}Y_{1-x} mixed cyanide crystals. X is an alkali metal (K, Na or Rb) and Y is a spherical halogen ion (Br, Cl or I).

Sympathetic Cooling of Mixed Species Two-Ion Crystals for Precision Spectroscopy [PDF]

open access: yes, 2012
Sympathetic cooling of trapped ions has become an indispensable tool for quantum information processing and precision spectroscopy. In the simplest situation a single Doppler-cooled ion sympathetically cools another ion which typically has a different ...

Bovine gallbladder mucin promotes cholesterol crystal nucleation from cholesterol-transporting vesicles in supersaturated model bile.

open access: yesJournal of Lipid Research, 1989
This study examined the ability of purified gallbladder mucin to accelerate the nucleation of cholesterol monohydrate crystals from the cholesterol-transporting particles in supersaturated model bile.

Vapor phase growth and properties of mixed layered Pb1-xCdxI2 semiconductors

open access: yesФізика і хімія твердого тіла, 2022
Pb1-xCdxI2 crystals (x = 0.1; 0.9) have been obtained by crystallization from a vapour phase in a closed system at over-stoichiometric iodine vapour pressure. An alloy of CdI2 and PbI2 was used as a source of evaporation. As a result of X-ray diffraction

On higher level Kirillov--Reshetikhin crystals, Demazure crystals, and related uniform models

open access: yes, 2019
We show that a tensor product of nonexceptional type Kirillov--Reshetikhin (KR) crystals is isomorphic to a direct sum of Demazure crystals; we do this in the mixed level case and without the perfectness assumption, thus generalizing a result of Naoi. We

Human serum albumin crystals and method of preparation [PDF]

open access: yes, 1989
Human serum albumin (HSA) crystals are provided in the form of tetragonal plates having the space groups P42(sub 1)2, the crystals being grown to sizes in excess of 0.5 mm in two dimensions and a thickness of 0.1 mm. Growth of the crystals is carried out
