Effect of crystalline transformation on supercritical CO2 foaming and cell morphology of isotactic polybutene-1

open access: yesJournal of CO2 Utilization, 2023
As a polycrystalline polymer, isotactic polybutene-1 (iPB-1) will form different crystalline structures when it crystallizes under different conditions. In this work, we found a simple method to manipulate the cell structure of iPB-1 foams by controlling

Calculation of the free energy of crystalline solids [PDF]

open access: yes, 2013
The prediction of the packing of molecules into crystalline phases is a key step in understanding the properties of solids. Of particular interest is the phenomenon of polymorphism, which refers to the ability of one compound to form crystals with ...

The first family of designable fortress-like alkyltin-oxo molecular cages: Ligand-regulated structural evolution and optical limiting effect

open access: yesNano Research
The development of organometal-oxo molecular cages remains challenging due to the difficulties associated with constructing novel structures through conventional bottom-up self-assembly methods. In this study, we present a rationally designed approach to

Incorporation of dysprosium ions into PbTiO3 ferroelectric ceramic system [PDF]

open access: yesJournal of Advanced Dielectrics, 2015
A structural analysis concerning the incorporation of dysprosium into A- and/or B-sites of the lead titanate is shown. The two "boundary" refinements are presented, i.e., Dy2+ substitutes for Pb2+ (Dy3+ substitutes for Ti4+) and Dy3+ substitutes for Pb2+

Crystallographic, Structural, and Electrical Properties of W6+ Substituted with Mo6+ in Crystalline Phases such as TTB Structure

open access: yes, 2023
Owing to their low dielectric loss and high permittivity values, dielectric ceramics have garnered a lot of interest from the scientific and industrial sectors. These properties allow for their downsizing and use in a variety of electronic circuits. This

Relative and Absolute Structure Assignments of Alkenes Using Crystalline Osmate Derivatives for X-Ray Analysis [PDF]

open access: yes, 2019
Osmium tetroxide and TMEDA form stable crystalline adducts with alkenes. The structure of liquid alkenes can be determined through X-ray analysis of these derivatives. Osmium, a heavy atom, facilitates the crystallographic analysis and the determination

Dynamical structure of αB-crystallin

open access: yesProgress in Biophysics and Molecular Biology, 2014
The human small heat-shock protein αB-crystallin is an extremely difficult molecule to study, with its inherent structural dynamics posing unique challenges to all biophysical and structural biology techniques. Here we highlight how the polydispersity and quaternary dynamics of αB-crystallin are intrinsically inter-twined, and how this can impact on ...
