The market of grid-level electricity storage is growing rapidly, with a predicted market value of 1.6 billion in 2012 and 8.3 billion in 2016. Electrochemical storages such as lead-acid, nickel-cadmium, sodium-sulfur and lithium-ion batteries are candidates with high potential for grid-level implementations. Among them, sodium-sulfur battery appears to be suitable for energy application while l...

The recovery of lead from spent acid battery paste (SLP) is not only related to the sustainable development industry, but also evolution environment. An innovative process proposed for high purity metallic by electrodeposition at 333–353 K in choline chloride-urea deep eutectic solvent (ChCl-urea DES). electrochemical behavior SLP on low carbon steel (LCS) electrode has been investigated cyclic...

A sensor node that is sending measurement updates regarding some physical phenomenon to a destination is considered. The sensor relies on energy harvested from nature to transmit its updates, and is equipped with a finite B-sized battery to save its harvested energy. Energy recharges the battery incrementally in units, according to a Poisson process, and one update consumes one energy unit to r...

Application of aromatic compounds has dramatically increased as raw materials in various industries and different factories have been established to produce aromatic compounds. The current research aims at characterizing industrial waste generation in aromatics production process in petrochemical industries and determining the best feasible alternative for waste disposal. For this purpose, the ...

in this paper, the development and optimization of power distribution control strategy (pdcs) have been performed for a hybrid energy storage systems (hess) of a series hybrid electric bus (sheb). a common pdcs is based on the use of ultra-capacitor (uc) pack. a new simple pdcs is developed as a battery based one. for the battery based pdcs, four parameters are introduced for tuning the pdcs pe...

among the power drills ( electrical/ pneumatic/battery ) used in orthopedic surgery, battery drill has got several advantages. surgeons in low resource settings could not routinely use orthopedic battery drills (obd) due to the prohibitive cost of good drills or poor quality of other drills. “hardware” or engineering battery drill (hbd) is a viable alternative to obd. hbd is easy to procure, ru...
