A proprietary water-soluble organic polymer (polymeric flocculant) of high molecular weight has been used to remove sediment from cooling water systems; current explanations of the mechanism are inadequate. A new flow-cell has been designed to study

In recent issues of the Medical Journal of Australia considerable interest has been shown in manipulation. Dr. B. Gard (1967) has suggested that statistical evidence be obtained from physiotherapy clinics as to the efficiency of manipulative treatmen

The space elevator was first proposed in the 1960s as a method of getting into space. The initial studies of a space elevator outlined the basic concept of a cable strung between Earth and space but concluded that no material available at the time ha

We report the successful operation of an optical cooler system. This device achieved 48 °C of cooling from room temperature and a heat lift of 25 mW when it was pumped with 1.6 W of laser light. Its performance as a function of pump laser wavelength

A full-scale compositional analysis of Yb3+-doped heavy metal fluoride glasses (HMFG) has been undertaken to determine potential hosts for use in the development of a first-generation optical cryocooler for space-borne remote sensing applications. By

Continual cooling of a material by anti-Stokes luminescence has been experimentally observed in a solid material. Net cooling was achieved by pumping to the lower levels of the 2F5/2 manifold of Yb3+, followed by population redistribution across this

A spacecraft in orbit around Jupiter's moon Europa can use ice penetrating radar to probe for a possible liquid water ocean beneath Europa's surface ice and to characterize other important subsurface structure. Consideration of available constraints

Laser-induced cooling of a solid by net anti-Stokes fluorescence, first experimentally demonstrated in 1995, can be the basis of a new type of cryocooler, an optical refrigerator. This article describes the physics and design issues of a practical op

The absorption and emission properties of Yb/sup 3+/-doped ZBLANP, BIGaZYT and QX/Yb phosphate glasses are studied to evaluate their potential for laser-induced fluorescent cooling or optical refrigeration. The efficiency of optical refrigeration inc
