Synthesis, characterization of ultrasmall gold nanocluster conjugated with Gemcitabine for anticancer activity.

The development of effective drug delivery strategy by employing novel nano-careers are advantageous for targeted and controlled drug release. The present work describes about such a strategy in the form of a protein stabilized ultrasmall gold nanocluster as nano-career for the delivery of anticancer drug Gemcitabine (Gem). Gold nanocluster (AuNCs) stabilized by bovine serum albumin (BSA) was synthesized and characterized in detail including its stability, size distribution, toxicity, and photo-physical properties.

Magnetic Compass Orientation in a Palaearctic-Indian Night Migrant, the Red-Headed Bunting.

Red-headed Buntings () perform long-distance migrations within their southerly overwintering grounds and breeding areas in the northern hemisphere. Long-distance migration demands essential orientation mechanisms. The earth's magnetic field, celestial cues, and memorization of geographical cues en route provide birds with compass knowledge during migration.

Frequency estimation techniques in capacitance-to-frequency conversion measurement.

The process of capacitance measurement consists of converting the capacitance under measurement into a secondary variable such as voltage, time-period, and frequency. This paper lays special focus on the capacitance-frequency measurement due to the offered advantages by this technique over the other methods. For this purpose, a review of the various frequency estimation techniques is presented while exploring the possibility of applying them for capacitance measurement.

Evaluation, comparison of different solvent extraction, cell disruption methods and hydrothermal liquefaction of macroalgae for biofuel production.

Cell disruption and lipid extraction methods for macroalgae are not well reported. Therefore, we compared various lipid extraction methods and extraction efficiency of various solvents to improve lipid yields from fresh water macroalgae. Lipid extraction was done by 2 methods viz.
