Also provided are methods of treating a subject with cancer of an organ or region comprising administering a chemotherapeutic agent to the organ or region, collecting blood laded with chemotherapeutic agent from the isolated organ, filtering the blood laden with chemotherapeutic agent to reduce the chemotherapeutic agent in the blood and returning the blood to the subject.
Biogenic activated carbon and methods of making and using same
Biogenic activated carbon compositions disclosed herein comprise at least 55 wt % carbon, some of which may be present as graphene, and have high surface areas, such as Iodine Numbers of greater than 2000. Some embodiments provide biogenic activated carbon that is responsive to a magnetic field. A continuous process for producing biogenic activated carbon comprises countercurrently contacting, by mechanical means, a feedstock with a vapor stream comprising an activation agent including water and/or carbon dioxide; removing vapor from the reaction zone; recycling at least some of the separated vapor stream, or a thermally treated form thereof, to an inlet of the reaction zone(s) and/or to the feedstock; and recovering solids from the reaction zone(s) as biogenic activated carbon. Methods of using the biogenic activated carbon are disclosed.
Thermal management system with sublimator and adsorbent bed
A thermal management system includes a space structure, a feed water container, a water feed line, a pump, and a filter device. The space structure includes a heat source connected with a fluid loop for conveying a working fluid through the heat source to regulate temperature and a sublimator connected with the fluid loop to receive the working fluid. The sublimator has a porous surface. The water feed line is connected with the container and the sublimator. The pump is located in the feed water line and is operable to move the feed water from the container to the sublimator. The sublimator is operable to cool the working fluid using the porous surface. The filter device is located in the water feed line between the pump and the feed water container. The filter device includes an adsorbent bed to remove organic compounds.
Porous material for storing of molecules and its use
The invention concerns new types of porous coordination polymers (MOF) and a method for their preparation. MOFs have been prepared through synthesis of salts of trivalent cations M.sup.3+, the source of which are aluminium, chromium, iron or yttrium salts, it is advantageous if of chlorides, nitrates or sulphates, with linkers carrying two or more phosphinic groups under presence of solvent. Linkers are phenylene-1,4-bis(R phosphinic acid) (PBPA) and biphenylene-4,4′-bis(R phosphinic acid) (BBPA). For the prepared MOFs, the structure has been tested using x-ray powder diffraction, specific surface and porousness which have been characterised through adsorption isotherm of nitrogen and further the stability of prepared MOFs has been determined using thermogravimetric analysis. All the prepared MOFs have been stable around 400° C. and have contained mesopores or micropores where hydrogen or CO.sub.2, for example, can be stored.
Water stable copper paddlewheel metal organic framework (MOF) compositions and processes using the MOFs
This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has open coordination sites and has been post synthesis modified by partially occupying the open sites with a ligand such as acetonitrile (CH.sub.3CN). The resultant MOF retains at least 40% of its as synthesized surface area after exposure to liquid water at 60° C. for 6 hours. This is an unexpected result versus the MOF which has not been post treated with ligands such as acetonitrile. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.
