The present invention discloses an electrified fiber sorbent formed from a support comprising a sorbent and a conductive material, and a manufacturing method therefor. The fiber sorbent according to the present invention is capable of efficiently adsorbing a relatively low concentration of carbon dioxide, particularly, carbon dioxide in the atmosphere, and an energy efficiency is good because the energy source required for desorption of carbon dioxide is free, and direct heating of the sorbent is possible.

A carbon monolith can include a plurality of carbon fibers fused together to form the carbon monolith. The plurality of carbon fibers are melt blown carbon fibers fused together at contact points. Each carbon fiber of the plurality of carbon fibers comprises a longitudinal resistivity of between about 1.5 m and about 20 m.

The invention relates to methods for regenerating a used sorbent having a gas adsorbate adsorbed thereto. In particular, the used sorbent comprises liquid marbles. The liquid in the liquid marbles is comprised of a material or mixture of materials that selectively removes unwanted gaseous component in the gas to be purified.

The electronic structure of nanowires, nanotubes and thin films deposited on a substrate is varied by doping with electrons or holes. The electronic structure can then be tuned by varying the support material or by applying a gate voltage. The electronic structure can be controlled to absorb a gas, store a gas, or release a gas, such as hydrogen, oxygen, ammonia, carbon dioxide, and the like.

A solar reactor useful in reaction processes, more particularly, useful in endothermic reaction processes, such as a catalyzed process or an adsorption-desorption process. The reactor comprises a reaction pathway defined by an exterior wall and an interior wall, the exterior wall comprising a solar radiation receiver capable of converting solar radiation into heat and transmitting the heat to the reaction pathway. The reaction pathway has disposed therein, in alternating fashion, a plurality of reactive elements comprised of a catalyst or a sorbent and a plurality of heat transfer elements.

Method and systems for rapidly desorbing a quantity of polar molecules from adsorbent material by exposing the adsorbent material to radio frequency energy are described.

Provided herein are methods of reducing bioburden of (e.g., sterilizing) a chromatography resin that include exposing a container including a composition including a chromatography resin and at least one antioxidant agent and/or chelator to a dose of gamma-irradiation sufficient to reduce the bioburden of the container and the chromatography resin, where the at least one antioxidant agent and/or chelator are present in an amount sufficient to ameliorate the loss of binding capacity of the chromatography resin after/upon exposure to the dose of gamma-irradiation. Also provided are reduced bioburden chromatography columns including the reduced bioburden chromatography resin, compositions including a chromatography resin and at least one chelator and/or antioxidant agent, methods of performing reduced bioburden column chromatography using one of these reduced bioburden chromatography columns, and integrated, closed, and continuous processes for reduced bioburden manufacturing of a purified recombinant protein.

The object of the invention is to provide an adsorbent that can adsorb ammonia with no large volume change between absorption and desorption, that has a high ammonia and/or ammonium ion adsorption capacity, and that can have an additional function by gaining proper control of composition, etc. The invention makes it possible to provide an adsorbent that absorbs ammonia and/or ammonium ions through the use of a metal cyanocomplex as an ammonia adsorbent, experiences no or little volume change, exhibits high enough capacity for adsorbing ammonia and/or ammonium ions, and has a function of decomposing ammonia as well as a function of varying optical responses before and after adsorption, etc.

The present invention relates to a filter material for water filters based on inorganic surfaces, whether they are natural or synthetic that it is regenerated after its first use and a method for activating and regenerating the filter material by the use of inert salt solutions and the energy provided by microwaves.
