The present investigation reports the application of ultrasonic energy (20 kHz) to few high sulphur Indian coal samples in aqueous and mixed alkali media (1:1 KOH and NaOH) for removal of sulphur and ash for industrial ...

This study illustrates a density functional theory (DFT) based approach to design the amine collectors with regards to their interaction with the quartz surface. Mechanism of interaction of primary aliphatic amines and ...

A new class of ternary Al-7Si-xMg alloys was developed with improved microstructure consisting of fine spheroidal Mg2Si and eutectic Si particles dispersed in alpha-Al. The studies show that Mg and Sr have a modification ...

Comparative studies of oleate interaction with hematite, magnetite and goethite using density functional calculations are presented. The approach is illustrated by carrying out geometric optimization of oleate on the stable ...

Fused mullite, a commonly used refractory material has been synthesized and adopted in the present study as reinforcement in the nickel composite coating. The composite has been developed through electrodeposition method. ...
