Effect of the sintering temperature on microstructure and optical properties of reactive sintered YAG:Sm3+ ceramics

Optical Materials: X, 2022
YAG:Sm3+ (5 аt.%) optical ceramics were obtained by the solid-state reactive sintering in the 1700–1800°C temperature range. The effect of the sintering temperature on the microstructure, phase composition and optical properties of YAG:Sm3+ ceramics has ...

Temperature-Controlled Diastereoselective Doebner/Ugi Tandem Reaction

SynOpen, 2023
Novel peptidomimetics containing a pyrrolone fragment were synthesized by a tandem combination of Doebner and Ugi type multicomponent reactions with controlled diastereoselectivity. This approach represents a convenient synthesis in the temperature range

Alkyl derivative of p-terphenyl as an activator of polysiloxane-based scintillator [PDF]

Ядерна фізика та енергетика, 2022
One of the problems in creating a radiation-hard scintillation composition on a polysiloxane base is the search for a radiation-hard activator capable of dissolving in such a base in sufficient quantity.

Single-Crystal Polycationic Polymers Obtained by Single-Crystal-to-Single-Crystal Photopolymerization

Journal of the American Chemical Society, 2020
The efficient preparation of single-crystalline ionic polymers and fundamental understanding of their structure-property relationships at the molecular level remains a challenge in chemistry and materials science. Here, we describe the single-crystal structure of a highly ordered polycationic polymer (polyelectrolyte) and its proton conductivity.

Alkyl derivative of p-terphenyl as an activator of the plastic scintillators with n/γ-discrimination ability [PDF]

Ядерна фізика та енергетика, 2023
In order to increase the solubility of p-terphenyl molecules, their structure was modified with tert-butyl groups. A derivative of p-terphenyl 2,4,4′-tris-tert-butyl-1,1′:4′,1′-terphenyl was obtained.

Single crystal to single crystal transformations [PDF]

Australian Journal of Chemistry, 2006
The past decade has witnessed escalating interest in solidstate phase transitions that involve significant changes in structure without appreciable loss of crystal mosaicity— single crystal to single crystal (SC-SC) transformation.[1–5] Several factors have contributed to these studies: increased general access to X-ray diffraction facilities ...

Photodriven single-crystal-to-single-crystal transformation [PDF]

Coordination Chemistry Reviews, 2017
Abstract Molecular architectures containing photosensitive units respond to light, giving dramatic variations of their structure. In particular, the crystalline packing phases offer the possibility of significant advances in crystal design and the understanding of solid-state photoreactivity.
