This study examined the effects of specific aminoquinoline molecules on the inhibition of aluminium corrosion in hydrochloric acid, as well as the effects of the amino group substituent at positions 5, 6, and 8. Experimental measurements using weight loss, EIS, and PDP were conducted. Six aminoquinolines (6-AMQ), seven aminoquinolines (7-AMQ), and eight aminoquinolines (8-AMQ) were used in different mass and temperature conditions with varying HCl concentrations to aid in weight loss. These inhibitors' adsorption properties were discovered to be in line with the long-muir isotherm; physical and chemical processes were all important. Comparatively speaking, 7-aminoquinoline performance was superior to 6- and 8-chloroquinoline, as indicated by the corrosion rate (CR), mass loss, percentage inhibition efficiency.........

This paper introduces an innovative high step-up converter featuring average mode control tailored for power generation applications. A comprehensive steady-state analysis of the system is provided, yielding transfer functions for input voltage versus output voltage and duty cycle versus output voltage. The study includes simplifications and design rules to streamline feedback loop design. The Sheppard Taylor Converter, designed to emulate non pulsing input and output currents akin to the Cuk Converter, operates with forward energy transfer. Employing two inductors to shape input currents and feed the output load, this converter minimizes input and output current ripple. Compared to the Cuk Converter, the Sheppard Taylor converter demonstrates superior regulation of output voltage with less variation in the duty cycle. This paper explores the Sheppard Taylor converter, its state space average model, and its application in high step-up converters crucial for renewable energy application.

The rise in the production of newest electronics has led to the older ones becoming outdated. The discarded obsolete electronics known as electronic waste or e-waste are disposed indiscriminately into the landfills where scavengers use crude methods of extraction to recover valuable parts of the e-waste. These crude methods such as open-burning and acid baths lead to the release of toxic substances into the environment. Most of these toxic substances persist in the environment and are non-biodegradable while some change into other substances that are more hazardous......

Water hyacinth (Eichhornia crassipes) is a floating aquatic weed and native of Amazon River. Water hyacinth is one of the fastest growing plants they primarily reproduce from runners or stolons. Each plant of E. crassipes can produce thousands of seeds each year and these seeds can remain viable for more than 28 years. Water hyacinth caused water loss through evapotranspiration which is more significant than indigenous weeds. Water hyacinth caused many problems in canals, ponds, lakes, rivers likes they are blocking of canals and causing floods, reduction of water quality, oxygen depletion, increased evapotranspiration rate, fish production problems, the beauty of ponds......
