The invention provides for a method of regenerating a solid adsorbent, such as a molecular sieve or activated carbon, using stable fluorinated hydrocarbon compounds such as, for example, HFC-245cb (1,1,1,2,2-pentafluoropropane, as a regeneration fluid.

Methods of dewatering viscous materials are provided. The method comprises contacting the viscous material with pressurized carbon dioxide at a temperature and for a time wherein at least a fraction of water is expressed from the viscous material. Then the pressure is released, and the water expressed from the viscous material is removed to yield a dewatered product. Exemplary viscous materials that can be dewatered by the method include black liquor from wood pulping operations, wet lignin, wet super water absorbent polymers and sugar solutions. The pressurized carbon dioxide is present in subcritical or supercritical form. The method provides dewatering at reduced cost.

A molded body includes a shape memory material. The molded body has a three-dimensional surface structure which, in a permanent shape, at least in part has a superhydrophobic surface and/or a hydrophobic surface, on which water droplet contact angles of 120° to 150° are found.

The present invention relates to a sorbent which is suitable for binding metals from solutions, the production of a corresponding sorbent as well as the use of the sorbent for binding metals from solutions.

Disclosed are magnetic nanoparticles and methods of using magnetic nanoparticles for selectively removing biologics, small molecules, analytes, ions, or other molecules of interest from liquids.

The invention generally relates to a carbon-based boron removal medium with hydroxyl group and amine group, and in particular, to a method for forming the carbon-based boron removal medium. In various embodiments, nitrogen-doped (“N-doped”) graphene oxide is synthesized by a simple two-step process: (1) oxidation of graphite to graphene oxide, and (2) nitrogen-doping (“N-doping”) the graphene oxide to form the amine group. The resultant N-doped graphene oxide can efficiently remove boron from aqueous solutions. The invention also generally relates to a boron sensing medium and its use in conductometric measurement techniques to detect and measure the amount of boron present in aqueous solutions.

This disclosure includes regenerated inorganic fermented beverage stabilization and/or clarification media and a process for such regeneration. Inorganic stabilization and clarification media (for processing beer or the like) may include expanded perlite or other expanded natural glasses, diatomaceous earth, silica gel or other precipitated silicas and compositions that incorporate these materials. Such media may be regenerated individually, together in a mixture or together as part of a composite product. The regenerated media meet the requirements for physical and chemical properties for re-use and replacement of the majority of particulate inorganic filtration media and inorganic stabilization media consumed in stabilization and clarification processes, and the related regeneration process provides for substantial benefits to brewers through a reduction of costs to purchase and transport stabilization and clarification media, to dispose of spent cake and/or membrane retentate, while providing for substantial reductions in the introduction of soluble impurities into the fermented beverage.
