In friction stir welding heat is generated by developing friction between the rotating tool and the workpiece material. This frictional heat is used for joining the workpiece. The friction stir welding produces economic joints due to lower consumption of power, no need for joint edge preparation, and also no gas shielding is required unlike in conv...

In this COVID-19 era, isolating people and reviewing their contacts has proven to be insufficient to control the COVID-19 pandemic as there was a huge gap between exposure to the virus and isolation due to the late onset of symptoms. This led to the spread of infection and people faced the consequences not only of viral infection, but also of finan...

Friction stir welding is a novel technique for joining ferrous and non-ferrous materials in a solid state. The groove fill techniques are most popular and generally used by researchers to dope reinforcement in the FSWed zone to improve the properties of joints. The main drawback of this technique is that a few amounts of reinforcement material come...

We have developed kinnow peel based bio-adsorbent for removal of cadmium from waste water. We have also developed recyclable bio-adsorbent. We recycled it up to 5 cycles. We also used various parameters for test of cadmium removal ability of bio-adsorbent like optimizing of pH, temperature of solution, dosage of adsorbent, contact time and solid-li...

This article investigates the effect of fabrication techniques on the physical, mechanical, and erosion wear properties of glass fiber reinforced dolomite dust‐filled epoxy composites. The composites were fabricated by hand layup and vacuum‐assisted resin transfer molding (VRTM) techniques with fixed glass fiber (20 wt%) and varying dolomite dust (...

The climati...

In this work, low-cost hybrid aluminium metal matrix composites were developed using wheat husk ash and red mud as reinforcement. Compositions varies from 5 to 15 wt%, through the stir casting process, and its mechanical characterizations (such as density, yield strength, ultimate tensile strength and Rockwell hardness) were calculated, and these r...

The crystallographic, morphological, and electrical properties of titanium dioxide (TiO2) and polyvinylidene fluoride (PVDF) composite film-like structure are prepared and examined at room temperature. The crystallographic-ray diffraction patterns, being proved to calculate the various phase of crystalline, having different weight percentage of TiO...

Water resources are exhausting rapidly due to misuse and wastes of water at industrial and household level, giving rise to the problem of the water crisis. Salty and wastewater can be recycled by distillation methods. However, distillation methods require energy input for water purification. Non-renewable energy resources, with skyrocketing prices...

Al2O3 and TiO2 water based nanofluids were used in heat exchangers to enhance the nusselt number. Tests were performed at different flow rates ranging between 2 LPM and 4 LPM. Concentrations of nanoparticles were taken from 0.1% to 0.3% by volume. Shell & tube heat exchangers having 14 tubes and Double pipe heat exchanger were used. The enhancement...
