The Zinc-air battery (ZAB) has become a hot research topic for nearly decade due to its high energy densities. As an important category of catalysts ZAB, perovskites have attracted extensive interests because their environmentally friendly properties, cheapness, and excellent electrocatalytic performances. This review article discusses the mechanistic analyses regarding progress ZAB. In additio...

In this study, a geotechnical assessment of gravel and sand deposits were conducted on both sides the Lower Zab River in southwest Kirkuk Governorate/Northern Iraq. geologically sediment related to Quaternary age tectonically located at unstable zone. 5 samples collected from study area for purpose conducting various tests them their validity road works sub-base layer base asphalt works.

Abstract The Makhoul Dam project proposed to be established is considered one of the strategic projects in Iraq as it works insurance large quantity water spare flood seasons, increase storage capacity dams Iraq, well food security. Makhool located on Tigris River Salah al-Din Governorate, and 8 km south meeting point with Lower Zab River. lake area about 256 km2. In this research, a mathematic...

Rechargeable Zn-air batteries (ZAB) have drawn extensive attention due to their eco-friendliness and safety. However, the lack of high-performance low-cost oxygen redox reactions (OER ORR) catalysts has become one main stumbling blocks in development. Herein, we successfully fabricate a CoFe nanobubble encapsulated nitrogen-doped carbon nanocage on wood support ([email protected]/WC) via pyroly...
