Continuous-Wave and Mode-Locked Operation of an In-Band Pumped Tm,Ho,Lu:CaGdAlO4 Laser

open access: yesApplied Sciences, 2023
We investigate in-band pumping of a Tm,Ho,Lu:CaGdAlO4 laser using a Raman-shifted Er-fiber laser (1678 nm), in the continuous-wave (CW) and mode-locked (ML) regimes.

Modeling Diffusive Mixing in Antisolvent Crystallization [PDF]

open access: yesCrystal Growth & Design, 2022
Diffusion controls local concentration profiles at interfaces between segregated fluid elements during mixing processes. This is important for antisolvent crystallization, where it is intuitively argued that local concentration profiles at interfaces between solution and antisolvent fluid elements can result in significant supersaturation overshoots ...

In-situ study on the coordinated deformation mechanism of austenitic stainless steel with mixed crystal degree

open access: yesJournal of Materials Research and Technology, 2023
A novel in-situ tensile experiment is designed to investigate the coordinated deformation mechanism between coarse grains (CGs) and fine grains (FGs) in the mixed crystal structure of X2CrNiMo18.12 austenitic stainless steel (X18.12).

Hydrodynamics and Mass Transfer during the Solution Growth of the K2(Co,Ni)(SO4)2•6H2O Mixed Crystals in the Shapers

open access: yesCrystals, 2020
Mathematical models of the hydrodynamics and mass transfer processes during the mixed crystal growth from low-temperature aqueous solutions have been analyzed. The features of these processes are caused by complex design of the crystallizer with a shaper.

Influence of cation substitution on optical constants of (Cu1-xAgx)7SiS5I mixed crystals

open access: yesSemiconductor Physics, Quantum Electronics & Optoelectronics, 2020
(Cu1–хAgx)7SiS5I mixed crystals were grown using the vertical zone crystalliza-tion method, they have been shown to crystallize in cubic structure (). The diffuse reflection spectra for the powders of (Cu1–хAgx)7SiS5I mixed crystals were measured at room

Mixed Crystal Disease: A Tale of 2 Crystals [PDF]

open access: yesThe Journal of Rheumatology, 2020
A report published in this issue of The Journal estimated the recurrence rate of acute calcium pyrophosphate (CPP) crystal arthritis and its associated factors1 on 111 patients with a first acute flare of CPP arthritis. Of these, 13 were considered to have gout on top of fulfilling the study’s definition of acute CPP crystal arthritis: 1 had monosodium

Seeking Rules Governing Mixed Molecular Crystallization

open access: yesCrystal Growth & Design, 2022
Mixed crystals result when components of the structure are randomly replaced by analogues in ratios that can be varied continuously over certain ranges. Mixed crystals are useful because their properties can be adjusted by increments, simply by altering the ratio of components.
