| 20120329888 | METHOD OF PRODUCING NANOPARTICLE SUSPENSIONS - Method of producing a nanoparticle suspension with the steps (i) preparation of an emulsion of a disperse polar phase, where the aqueous phase comprises one or more precursor substances forming the nanoparticles, in a continuous organic phase in the presence of an emulsifier stabilizing the emulsion, (ii) conversion of the one or more precursor substances to nanoparticles in the disperse aqueous phase, (iii) breaking of the emulsion and phase separation, where the nanoparticle suspension is obtained as one phase, (iv) separation off of the nanoparticle suspension, (v) optionally isolation of the nanoparticles from the nanoparticle suspension, wherein the emulsifier is selected from compounds of the general formula (I) in which X is O, NH, Y is C(O), NH, R is a saturated or a mono- or polyunsaturated, linear or branched hydrocarbon radical having 6 to 30 carbon atoms and R | 12-27-2012 |
| 20130053455 | INJECTING WATER TO EXTRACT OIL FROM A MATERIAL - A method for extracting oil from a compressible solid material including oil droplets contained within respective droplet tissues includes injecting liquid water into the compressible solid material; mixing the liquid water into the compressible solid material; if the liquid water is not in a sub-critical condition, bringing the liquid water to the sub-critical condition; and vaporizing the liquid water for releasing energy into the compressible solid material. The released energy ruptures the tissues around at least one of the respective oil droplets for releasing the oil droplets from containment within the respective droplet tissues. The released, oil droplets are extractable by compressing the compressible solid material. | 02-28-2013 |
