Application of Two-Dimensional Correlation Analysis to Explosives Detection and Polymer Crystallization [PDF]

open access: yes, 2010
This thesis presents two novel applications of two-dimensional (2D) correlation analysis: (1) long standoff detection of explosives and (2) morphology development in semicrystalline materials. Due to the dangers of improvised explosive devices (IEDs),

The Diminishing Role of the Nucleation Rate as Crystallization Develops in Avrami-Type Models

open access: yesSolids, 2022
By making use of an isothermal crystallization kinetics formulation in which growth and nucleation rates are functions of the degree of crystallization, we describe a process consisting of birth and growth of spherical crystalline domains.

Secondary Crystallization of Isotactic Polystyrene [PDF]

open access: yes, 1974
When isotactic polystyrene (i-PS) is crystallized from the melt or from the glassy state at rather large supercooling an additional melting peak appears on the curve during scanning in a differential calorimeter.

Dressed active particles in spherical crystals [PDF]

open access: yesSoft Matter, 2016
We investigate the dynamics of an active particle in two-dimensional spherical crystals, which provide an ideal environment to illustrate the interplay of active particle and crystallographic defects. A moving active particle is observed to be surrounded by localized topological defects, becoming a dressed active particle.

Lateral growth of cylinders

open access: yesNature Communications, 2022
Precise control of the microstructure of nanomaterials is of interest but living lateral growth of cylinders is still very challenging. Here, the authors propose a crystallization-driven fusion-induced particle assembly strategy to prepare cylinders with

Preparation and Characterization of Nanoparticles of Amorphous Cefmenoxime Hydrochloride

open access: yesChemical Engineering Transactions, 2016
Poor water solubility of cefmenoxime hydrochloride greatly limits its bioavailability and clinical application. The decreasing of the particle size could significantly enhance the solubility of the solute.
