Light scattering study of algal floc growth and structure: alum polymeric plant-derived flocculant.

The flocculation dynamics of algal cultures using alum and aqueous seed extracts as flocculants were analyzed through light scattering and fractal analysis. Floc growth in continuously stirred suspensions, with cell densities ranging from 200 to 800 μg L chlorophyll (Chl ), exhibited distinct patterns in fractal dimension () evolution relative to floc size: a smooth, monotonic increase; stochastic increase; and stabilization or leveling off. values ranged from 1.

A selective, sensitive and fast LC-MS/MS method for cabotegravir quantification in rat plasma and pharmacokinetic investigations.

This study presents a novel liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for quantifying cabotegravir (CAB) in rat plasma. A novel, sensitive, and rapid LC-MS/MS method has been developed and validated. Furthermore, protein precipitation technique allowed us to lowered the limit of quantification (LOQ) to nanogram levels, allowing detection of smaller CAB amounts in plasma samples.

Design and development of efficient and compact 20 kW 325 MHz solid-state amplifier for superconducting accelerator applications.

An efficient and compact, 20 kW solid-state power amplifier (SSA) at 325 MHz has been designed and developed in-house, using single stage combining. It comprises of 24 nos. of 1 kW power amplifier (PA) modules, a 24-way Wilkinson power combiner and divider, and other peripheral systems.

Experimental investigation of the adsorption and desorption of cellulase enzymes on zeolite-β for enzyme recycling applications.

The recyclability of cellulase enzymes using zeolite and polyethylene glycol (PEG) was investigated. The cellulase enzymes from cellulose hydrolysate suspensions were adsorbed onto zeolite-β under typical working conditions (pH 5). PEG having a molecular weight of 200 Da and 20 kDa was used as an eluent to desorb the cellulase enzymes from zeolite-β.
