An evaporator is provided that includes a porous sintered body. The porous sintered body is formed by a composite of at least one electrically conductive material and at least one dielectric material. The sintered body has an open porosity in a range from 10 to 90% and an electrical conductivity in a range from 0.1 to 105 S/m. The fraction of electrically conductive material in the sintered body is a maximum of 90 wt. %.

A lightweight modified filter material, a preparation method therefor and use thereof, the lightweight modified filter material being prepared from the following components in parts by mass: 75-100 parts of waste glass, 5-20 parts of a metal oxide modifier and 1-10 parts of a foamer. The lightweight modified filter material has the advantages of being lightweight, having large specific surface area, a high isoelectric point, porosity and the like, increasing the isoelectric point and service life of the filter material. The added metal oxide can be combined with SiO2 in the glass to form Si—O-Me (Me metal ions) and enter the glass network.

Systems and methods are disclosed for vaporization suppression. Vaporization suppression may include, for example, evaporation control and/or odor control. A layer of foam glass aggregates may be placed on a body of water. Bodies of water may include natural and man-made aqueous bodies (such as, for example, ponds, lakes, lagoons, reservoirs, tanks, pools, runoff areas, etc.). Water may include clean water, natural water, rainwater, runoff, industrial output, manure slurries, leachates, treatment effuse, etc.). When placed, the foam glass aggregates in contact with the water may have a first moisture content. At equilibrium, the foam glass aggregates in contact with the water may have a second moisture content. The second moisture content may be greater than the first moisture content. The foam glass aggregates in contact with the water may have a bulk density at the second moisture content that is sufficient to maintain buoyancy at the surface of the body of water.

The invention discloses porous, bioactive glass and glass ceramic morsels or pellets to be used as tissue graft substitute materials and processes for obtaining the same wherein the bioactive glass and glass ceramic morsels or pellets are made up of natural agents like phosphate, calcium, sodium and other elements which are not alien to the human or animal body. The said preparation process encompasses various steps like quenching sintering, foaming, and sol-gel casting which render the glass morsels or pellets unique bioactivity and enhanced porosity which may facilitate tissue repair and augmentation during tissue graft replacement.
