Preparation of Lead, Lead Alloy(S) And Other Salts from Exhausted Rechargeable Lead Batteries

by Mahmoud Abdel-Hamed Rabah, Maie Ibrahim Abdul Aziz El-Gammal, Mahmoud Salem Ibrahim and Omar Mohamed Helmy Abdul Aziz

Advances in Science, Technology and Engineering Systems Journal, Volume 4, Issue 4, Page # 529–538, 2019; DOI: 10.25046/aj040464

Abstract:

Metals of lead and some lead alloys, lead oxide, nickel and cobalt were recovered from exhausted battery by combined hydrometallurgy and pyro metallurgical method. The spent batteries were dismantled and leached in hot 2M and 5M nitric acid. The unleached fraction was heated with sodium carbonate to produce lead oxide. Salts in the leached solution…

Advanced Hybrid Energy Harvesting Systems for Unmanned Aerial Vehicles (UAVs)

by Cuong Van Nguyen, Toan Van Quyen, Anh My Le, Linh Hoang Truong and Minh Tuan Nguyen

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 1, Page # 34–39, 2020; DOI: 10.25046/aj050105

Abstract:

The recent use of rotary-wing unmanned aerial vehicles (UAVs) has gained significant interest and continuously been implemented since they are used across the world for civilian, commercial, as well as military applications. The drawback of UAVs is the fight-time due to the limited battery capacity. Therefore, energy harvesting (EH), captured energy from the ambient environment…
