We report a rational synthesis of maghemite (c-Fe 2 O 3) short-nanotubes (SNTs) by a convenient hydro-thermal method and subsequent annealing process. The structure, shape, and magnetic properties of the SNTs were investigated. Room-temperature and low-temperature magnetic measurements show that the as-fabricated c-Fe 2 O 3 SNTs are ferromagnetic, and its(More)
This study constructed a parameter analysis for improving the energy performance of air-cooled water chillers by altering the angle configuration of the condenser coils. The mathematical models for energy and exergy analyses of the individual components and overall system of air-cooled water chillers are presented. This study investigated the potential(More)
