Extraction of diosgenin using different techniques from fenugreek seeds- A review.

Diosgenin, falls under the category of steroidal saponin present in fenugreek seeds (Trigonella foenum-graecum) in the amount of 0.2-09%. This compound possesses certain pharmacological characteristics like anti-inflammatory, anti-cancer, anti-oxidant etc.

Investigation of thermal conductivity and thermal performance of heat pipes by structurally designed copolymer stabilized ZnO nanofluid.

The present study concentrated on estimating the thermal conductivity, stability, efficiency, and resistance of a heat pipe for heat exchangers, which were essential for many industrial applications. To achieve this, copolymer of amphiphilic poly (styrene-co-2-Acrylamido-2-methylpropane sulfonic acid) poly (STY-co-AMPS) was synthesized by free radical polymerisation technique. The dispersant were used for homogeneous solution and stabilization of ZnO nanofluids.
