Crystal structure dependence of the energy transfer from tb(III) to yb(III) in metal–organic frameworks based in bispyrazolylpyridines [PDF]

open access: yes, 2020
Luminescent mixed lanthanide metal−organic framwork (MOF) materials have been prepared from two polyheterocyclic diacid ligands, 2,6-bis(3-carboxy-1-pyrazolyl)pyridine and 2,6- bis(4-carboxy-1-pyrazolyl)pyridine. The crystal structures of the two organic

Multicomponent mixtures for cryoprotection and ligand solubilization

open access: yesBiotechnology Reports, 2015
Mixed cryoprotectants have been developed for the solubilization of ligands for crystallization of protein–ligand complexes and for crystal soaking. Low affinity lead compounds with poor solubility are problematic for structural studies.

THE FORMATION MECHANISM OF ASSEMBLED COMPLEXES BRIDGED BY1,3–BIS(4–PYRIDYL)PROPANE [PDF]

open access: yesChemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2016
Several types of crystals having different color appeared in the synthesis of assembled complex of mixed crystals with three metals. [H2(bpp)][M(NCS)4] changed to 1D chain polymer (M(NCS)2(bpp)) by releasing HNCS from the cation and anion in a reaction ...

Modelling micro- and macrophysical contributors to the dissipation of an Arctic mixed-phase cloud during the Arctic Summer Cloud Ocean Study (ASCOS) [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
The Arctic climate is changing; temperature changes in the Arctic are greater than at midlatitudes, and changing atmospheric conditions influence Arctic mixed-phase clouds, which are important for the Arctic surface energy budget.

Production of TiO2 with Scrap Collected by Trap in the TiN Process [PDF]

open access: yesArchives of Metallurgy and Materials
This study synthesized nano-sized TiO₂ using scrap from the TiN thin film manufacturing process by a hydrothermal reaction. By controlling the reaction temperature and concentration, the crystal structure and particle size were controlled.

Flexible Förster resonance energy transfer‐assisted optical waveguide based on elastic mixed molecular crystals

open access: yesAggregate, 2023
Flexible molecular crystal waveguides based on elastic molecular crystals (EMCs) are essential in flexible and compact optical materials. An increased loss coefficient α due to self‐absorption is often a problem in optical waveguides (OWGs) of ...
