The dynamics of spin waves during their multimode propagation in a magnonic crystal, which is an irregular narrow ferrite waveguide with periodic boundary modulation, has been studied by the method Mandelstam--Brillouin spectroscopy. transformation mode composition propagating shown. space-time and characteristics band gaps crystal are experimentally studied, possibility controlling frequency-s...

The role of frustration and quenched disorder in driving the transformation of a crystal into a glass is investigated in quasi-two-dimensional binary colloidal suspensions. Frustration is induced by added smaller particles. The crystal-glass transition is measured to differ from the liquid-glass transition in quantitative and qualitative ways. The crystal-glass transition bears structural signa...

Actin filament nucleation, polymerization, and branching are crucial steps in many forms of cell motility, cell shape, and intracellular organelle movements in a wide range of organisms. Previous biochemical data suggests that an anti-parallel actin dimer can incorporate itself into growing filamentous actin (F-actin) and has a role in branching. Furthermore, it is a widespread belief that nucl...

Quinones are widely found in nature, used in chemistry and medicine, and are just beginning to gain importance in materials engineering. In order to harvest their potential as an ordered or highly crystalline solid, their crystal formation processes need to be well investigated and controlled. We chose 1,4-anthraquinone, a commercially available type of quinone, as a model compound to study its...

the crystal structure of the title schiff base complex is obtained by single-crystal x-ray diffraction data.the solid state structure determination reveals that the coordination geometry around the copper(ii) center istetrahedrally distorted square-planar. the crystal packing shows one dimensional infinite chains which arisesfrom the intermolecular interaction and stabilize the crystal packing.

Phase transformations can be difficult to characterize at the microscopic level due to the inability to directly observe individual atomic motions. Model colloidal systems, by contrast, permit the direct observation of individual particle dynamics and of collective rearrangements, which allows for real-space characterization of phase transitions. Here, we study a quasi-two-dimensional, binary c...

The influence of two structurally different anionic surfactants on the anhydrous-to-dihydrate transformation of carbamazepine (CBZ) was investigated. The surfactants studied were sodium lauryl sulfate (SLS), a surfactant commonly used in compendial dissolution methods, and sodium taurocholate (STC), an important surfactant in the solubilization and absorption of drugs and lipids in the gastroin...

The thermodynamic transition temperature is a key parameter to ascertain when assessing the properties of a crystalline hydrate. The transition temperature is sometimes difficult to determine experimentally due to rapid transformation between the two crystal forms in solution. In this study, a new approach for determining the transition temperature is presented, utilizing the temperature depend...

We study simply laminated microstructures of a martensitic crystal capable of undergoing a cubic to orthorhombic transformation of type P ! P 0 . The free energy density modeling such a crystal is minimized on six energy wells that are pairwise rank-one connected. We consider the energy minimization problem with Dirichlet boundary data compatible with an arbitrary but xed simple laminate. We rs...

The alpha-polymorph of ortho-ethoxy-trans-cinnamic acid (OETCA) undergoes a reversible single-crystal-to-single-crystal phase transformation at 333 K. The new high-temperature polymorph (alpha'-OETCA) is stable between 333 and 393 K with three molecules in the asymmetric unit (Z' = 3), space group P1;. Unlike the other polymorphs (and solvate) of OETCA recently reported, two of the molecules in...
