this paper discusses about preparation of biodegradable polymer /clay nanocomposites based on organically modified montmorillonite clay; i.e. cloisite 10a and biodegradable polymer chitosan by solution mixing technique and their characterization. the nanocomposites were successfully prepared and their structures were characterized by powder x-ray diffraction (xrd), particle size analyzer (beckm...

The use of an inorganic phase in water-in-oil microemulsions has received considerable attention for preparing metal particles. This is a new technique, which allows preparation of ultrafine metal particles within the size range 5 nm<particle diameter<50 nm. This article presents a review of the current literature in the field of particle preparation of several metals such as silver, copper, ca...

CEC is a high performance electrodriving liquid phase separation technique. It does not need complex and sophisticated high pressure instrumentation for nanoflow driving. This is attractive for parallel multicolumn analysis. To this end, high throughput methods for column preparation are needed to support the use of multiple columns. In this study, we directly used CEC mobile phase solution as ...

A dispersed particle gel (DPG) was successfully prepared from a polymer gel at room temperature. The polymer gel system, morphology, viscosity changes, size distribution, and zeta potential of DPG particles were investigated. The results showed that zirconium gel systems with different strengths can be cross-linked within 2.5 h at low temperature. Scanning electron microscopy (SEM), transmissio...

− The paper deals with a fast measurement technique of electromagnetic transients due to eddy currents in fast-cycled magnets for linear particle accelerators. First the context of the problem, related to the need for accurate control of the magnetic field quality in order to ensure the stability and performance of the particle beam in dynamic conditions (field ramps up to about 700 T/s) is out...

Overview and preliminaries. The study of interacting particle systems with conservation laws frequently revolves around hydrodynamic limits, in which the long-time, large-length scale behavior of a system is characterized by the evolution of the local density of the conserved quantity according to a partial differential equation. The typical setup consists of a particle system defined on a clos...
