The need to cure fly ash-based geopolymer at elevated temperatures has limited the practicability and sustainability of the composite. Hence, there is an imminent need to find ways at which fly ash-based geopolymers can ...

In the present scenario, petroleum resource-based thermoset materials have become an environmental threat due to their permanent cross-linked structure that limits their recyclability. To overcome this problem, the development ...

Many practical noises emanating from rotating machines with blades generate a mixture of tonal and the chaotic noise. The tonal component is related to the rotational speed of the machine and the chaotic component is related ...

A novel continuous production and extraction of bacterial bioactive prodigiosin (PG) from fermented using silver nanoparticle impregnated functioned activated carbon composite is proposed for cost-effective and ecofriendly ...

GaN:SiO2 nanocomposites were successfully synthesized by a two-step process. Firstly, an intermediate xerogel was obtained by the sol-gel method and, in the second step, annealing the powdered samples at 900 degrees C for ...

Galvanic interaction between galena and manganese dioxide in hydrochloric acid medium was studied through polarization measurements conducted on compact disc electrodes of the minerals under different [H+] (0.025-0.2M) and ...

This paper examines galvanic interaction of the MnO2-FeS2 couple through polarization and leaching studies. Large galvanic currents, observed between electrodes of this couple, increase further with an increase in H+ ...

Galvanic interactions between sphalerite and manganese dioxide in sulphuric acid medium have been investigated through measurement of self-corrosion potential as well as mixed potentials of these two mineral electrodes and ...

Gas dispersion is one of the key factors in the mineral flotation process articulated by many variables such as bubble size, gas hold-up, gas superficial velocity and bubble surface area flux (S-b). In this work, experiments ...
