COLLOIDAL COMMON SALT

Electrophoresis of colloidal dispersions in the low-salt regime.

We study the electrophoretic mobility of spherical charged colloids in a low-salt suspension as a function of the colloidal concentration. Using an effective particle charge and a reduced screening parameter, we map the data for systems with different particle charges and sizes, including numerical simulation data with full electrostatics and hydrodynamics and experimental data for latex disper...

Salt-induced lipid transfer between colloidal supported lipid bilayers†

Heterogeneous drying of colloidal polymer films: dependence on added salt.

Using magnetic resonance profiling coupled with dynamic light scattering, we have investigated the mechanisms leading to the formation of a partly coalesced surface layer, or "open skin", during film formation from waterborne polymer dispersions. We present the first use of the skewness of the distribution of free water as a model-free indicator of the spatial nonuniformity of drying. The skewn...

Common salt iodization status in urban areas of Ujjain (M.P.)

Iodine deficiency disorders (IDD) are prevalent in all states of India. IDD continue to be high despite ban on the sale of non-iodised salt. In order to assess the effectiveness of salt iodization programme, a study was undertaken to analyse the iodine content of salt samples sold in Ujjain (M.P.). 108 salt samples, commercially available to general public, were collected at retailer level from...

Microarray analysis of salt-responsive genes in common wheat

We developed oligo-DNA microarrays of common wheat. These microarrays were designed to include approximately 32,000 unique genes represented by a large number of expressed sequence tags (ESTs). In order to characterize the salt-responsive genes in common wheat, the expression profiles of transcripts that responded to salt-treatment were monitored using the microarrays. Two-week-old seedlings of...
