Background & Aim: Ultrasound hyperthermia with nanoparticles has been regarded as an effective method for localized death of cancerous cells with fewer side effects to the surrounding normal tissues. The aim of this study was to investigate the increasing of water temperature by ultrasound waves in the presence of graphene oxide (GO) nanoparticles in order to be used in thermal treatment of can...
Five years after a 1983 Washington State law required new water heaters to be preset at 49 degrees C (120 degrees F), 77% of homes (84% of homes with postlaw and 70% of homes with prelaw water heaters) had tap water temperatures of less than 54 degrees C. In 1977, 80% of homes had tap water temperatures greater than 54 degrees C. Mean temperature in 1988 was 50 degrees C compared with 61 degree...
This semester project investigates strategies aimed at controlling the aggregate power demand of large groups of domestic electric water heaters. An existing model of a single electric water heater that considers thermal stratification along the height of the hot water tank was tuned and verified using experimental data. The tuned model was then incorporated into an existing model of a water he...
Solar desiccant cooling is widely considered as an attractive replacement for conventional vapor compression air conditioning systems because of its environmental friendliness and energy efficiency advantages. The system performance of solar desiccant cooling strongly depends on the input parameters associated with the system components, such as the solar collector, storage tank and backup heat...
In plants, transpiration draws the water upward from the roots to the leaves. However, this flow can be blocked by air bubbles in the xylem conduits, which is called xylem embolism. In this research, we present the design of a biomimetic microfluidic pump/valve based on water transpiration and xylem embolism. This micropump/valve is mainly composed of three parts: the first is a silicon sheet w...
