Methyl 8-oxo-2-phenyl-1-oxaspiro[4.5]deca-2,6,9-triene-3-carboxylate

IUCrData, 2016
The title compound, C17H14O4, is a 5/6 spiro-ring fused system, where the five- and six-membered rings are inclined to one another by 89.79 (5)° at the spiro-carbon. In the crystal, non-classical C—H ... O hydrogen bonds form inversion dimers and connect

The Kolmogorov equation in the stochastic fragmentation theory and branching processes with infinite collection of particle types

Abstract and Applied Analysis, 2006
The stochastic model for the description of the so-called fragmentation process in frameworks of Kolmogorov approach is proposed. This model is represented as the branching process with continuum set (0,∞) of particle types. Each type r∈(0,∞) corresponds

Reversible Single-Crystal-to-Single-Crystal Phase Transition of Chiral Salicylidenephenylethylamine

Crystals, 2016
The chiral crystal of enantiomeric (S)-N-3,5-di-tert-butylsalicylidene-1-phenylethylamine in the enol form [enol-(S)-1] undergoes a reversible single-crystal-to-single-crystal (SCSC) phase transition at Tc ≈ 3 °C from the room temperature α-form in ...

Presence of Uterine Leiomyomas Has No Significant Impact on Gene Expression Profile in the Scalp of Patients with Central Centrifugal Cicatricial Alopecia

JID Innovations, 2022
Central centrifugal cicatricial alopecia (CCCA) is associated with increased expression of genes implicated in fibroproliferative disorders and a higher prevalence of uterine leiomyomas (ULs) among affected individuals. We sought to examine the effect of

Crystal Growth of Single Salicylamide Crystals [PDF]

Crystal Growth & Design, 2019
Growth of single salicylamide crystals was investigated in a nonstirred growth cuvette and on a rotating disk. In the growth cuvette the crystal growth rates were measured for both primary nucleated crystals and seed crystals manually inserted into the cuvette.

A novel mechanism to generate metallic single crystals

Scientific Reports, 2021
Generally, the evolution of metallic single crystals is based on crystal growth. The single crystal is either produced by growing a seed single crystal or by sophisticated grain selection processes followed by crystal growth.

Influence of chemical substitution on broadband dielectric response of barium-lead M-type hexaferrite

New Journal of Physics, 2019
We report on the electrodynamic properties of the single crystalline lead-substituted M-type barium hexaferrite, Ba _0.3 Pb _0.7 Fe _12 O _19 , performed in the broad frequency range including radio-frequency, terahertz and sub-terahertz bands, which are
