Abstract:
Disclosed is a method and an apparatus enabling water-conditioning processes to be performed using a heater initially equipped with an aquarium tank for the purpose of supplying heat. Instead of allowing heat to propagate globally, reactor housing is introduced in the tank enclosing the heater so as to form a localized hot zone. The temperatures of the hot zone are maintained at high degrees sufficient to initiate various water-conditioning processes with efficiency, including alga control, ammonia control, water-hardness control, and sterilization. The construction of the reactor housing is simple and inexpensive, and its geometry is compatible to a heater which can be purchased commercially. In short, multiple functions are added to a heater installed in an aquarium, performing water-conditioning processes in addition to the basic task of supplying heat, allowing water quality of the aquarium to be improved and maintained.
Abstract:
A phase change material comprising a quaternary GaTeSb material consisting essentially of MA(GaxTeySbz)B, and where M comprises a group IVA element C, Si, Ge, Sn, Pb, a group VA element N, P, As, Sb, Bi, or a group VIA element O, S, Se, Te, Po, having a value A such that the transition temperature is increased relative to the transition temperature in GaxTeySbz, without M, and the difference between the melting temperature and the transition temperature is reduced relative to the difference in GaxTeySbz, without M.
