Transient batteries play a pivotal role in the development of fully autonomous transient devices, which are designed to degrade after period stable operation. Here, new separator-electrolyte pair is introduced for lithium ion batteries. Cellulose nanocrystals (CNCs) selectively located onto nanopores polyvinyl alcohol membranes, providing mobile ions interact with liquid electrolyte. After lith...

Sediment Bypass Tunnels (SBTs) are deviant channels that convey the current containing sediments from the upstream of the reservoir to the downstream of the dam. In this research, by applying submerged plates on the entrance of a 90-degree diversion channel for sediment transport, the effect of hydraulic parameters of flow and changes in the angle of plates on sediment transport and deviated fl...

A heat transfer model was developed for a new non-electric infant’s transport incubator. The source of heat comprises a super saturated solution of Sodium Acetate and a metal disk (activator) in a plastic container. Estimating the number of the chemical bags required for different ambient temperature was the goal. First the quantity of heat generated by the chemical was appointed through experi...
