Abstract: The present disclosure relates to ?-class carbonic anhydrase polypeptides having improved properties including increased thermostability and/or stability in the presence of amine compounds, ammonia, or carbonate ion. The present disclosure also provides formulations and uses of the polypeptides for accelerating the absorption of carbon dioxide from a gas stream into a solution as well as for the release of the absorbed carbon dioxide for further treatment and/or sequestering. Also provided are polynucleotides encoding the carbonic anhydrase polypeptides and host cells capable of expressing them.

Abstract: A transmissive beam steering aperture includes a common superstrate provided from an optical material and having first and second opposing surfaces with at least one of the first and second surfaces having an electrode coating provided thereon to provide the at least one surface as a common electrode surface and having a first plurality of electrically isolated common electrodes. One or more electrode containing substrates is disposed over respective ones of the first plurality of electrically isolated common electrodes to form one or more one liquid crystal (LC) cells. In one embodiment, the transmissive beam steering aperture is used as an aperture in an optical phased array.

Abstract: Described herein are structures and techniques for providing an LC cell having a hermetically sealed cover disposed over a fill hole provided in a superstrate. The superstrate and cover have adhesion layers disposed thereon. Solder is disposed or otherwise provided around the fill hole (e.g. either on the cover or the superstrate or as a separate piece). The cover is then disposed over the fill hole and the solder is reflowed to form the hermetic seal over the fill hole.

Abstract: A method is described for environmentally sound usage of combustible hazardous waste in an operating rotary kiln. The method is particularly adapted for disposal of solid hazardous wastes, optionally in the form of a blended waste homogenate, packaged in sealable containers. The containers are used as fuel modules and charged into a rotary kiln cylinder where kiln gas temperatures range from about 950.degree. to about 1200.degree. C. to achieve high destruction and removal efficiencies.
