20100258429 | METHOD USING SOLAR ENERGY, MICROWAVES AND PLASMAS TO PRODUCE A LIQUID FUEL AND HYDROGEN FROM BIOMASS OR FOSSIL COAL - A system uses thermal solar energy coupled with microwaves and plasma for producing carbon monoxide (CO) and dihydrogen (H2) from carbonated compounds (biomass, domestic waste, sludge from waste water, fossil coal), wherein the obtained gaseous mixture yields, amongst others, hydrocarbon fuels (olefins, paraffin), esters, and alcohols via a Fischer-Tropsch synthesis. In a first step the carbonated compounds are roasted and pyrolized to produce char and dry coal, and a mixture of superheated gases containing CO2, steam, tars and non-condensable volatile materials. The method includes in a second step, and from the pyrolyis products (char or coal, gas mixture), generating a syngas substantially containing a mixture of carbon monoxide and dihydrogen, the mixture being used in Fischer-Tropsch synthesis units. After the Fischer-Tropsch step, the synthesis products are separated in a distillation column after heating in solar furnaces of mixed furnaces (solar/microwave). | 10-14-2010 |
20110109904 | Method and Device for High Speed Quantitative Measurement of Biomolecular Targets on or in Biological Analysis Medium - The present invention relates to a device and method for the high speed quantitative measurement of biomolecular targets on the surface or in the body of a planar medium for biological analysis. The method, according to the invention, includes the following, steps: a) at least two laser beams (F″) are focused and overlaid on each measuring point of said medium by the simultaneous intersection of these beams to extract a contained hot plasma (P), including a measured chemical element present in the targets and another chemical element exogenous to the targets and present in a known quantity on this medium; b) luminous emission rays for each plasma, corresponding to the quantified element and exogenous element, are detected and anglyset each measuring point while measuring the brightness of these rays; then c) the concentration in each measuring point of the quantified element is determined through prior calibration of the rays of the qualified element to determine a correlation between the brightness of the rays, specific to said element, and the concentrations the latter in mixtures of the quantified element and the exogenous element in known proportions. | 05-12-2011 |
20110174605 | METHOD FOR THE DESALINATION OR PURIFICATION OF WATER BY DISTILLATION OF A SPRAY (SPRAY PUMP) - A system enables the use of solar heat energy together with electromagnetic energy and optionally energy produced during fermentation of organic products to produce fresh water from salt water, wastewater and water vapor contained in the atmosphere. The resulting fresh water can optionally be rendered drinkable by adding mineral salts at the desired concentration. A method and reactors combine electromagnetic and solar heating steps and optionally heat exchanges with a hot gas originating from combustion, to evaporate droplets of a spray produced from salt water or wastewater. The vapor obtained is separated from the salt particles or agglomerated impurities during evaporation using a cyclone system. The vapor can then be transported over a large distance before being condensed by bearings, in order to separate the water from any additives or impurities that may be present. Additives can be used to lower the vapor pressure of the liquid water and to facilitate droplet fractionation. | 07-21-2011 |
20130012400 | METHOD AND DEVICE FOR SEPARATING MOLECULAR TARGETS IN A COMPLEX MIXTURE - The invention relates to a method of analysing molecular targets contained in a complex mixture, comprising the following steps consisting in: a) bringing the mixture of molecular targets to be analysed into contact with an array of different types of primary probes, whereby each type of primary probe forming the array can bind specifically to a type of target selected from among the molecular targets, under conditions that enable specific binding between the molecular targets and the primary probes; b) optionally eliminating the primary probes that are not bound specifically to a molecular target; c) separating the molecular targets and the primary probes which are bound specifically in a probe/target complex, such as to recover the array of primary probes representing a fingerprint of the molecular targets to be analysed; and d) quantitatively analysing the primary probes eluted in step c. | 01-10-2013 |
20130101665 | SELF-ASSEMBLING HALF-ANTIBODIES - Novel chimeric molecules, termed “half-antibodies”, which are capable of self-assembling to form an epitope recognition site. Using these half-antibodies or a vesicle, a viral particle, a composition or a kit thereof, for therapeutic applications, such as the prevention or treatment of cancers, genetic diseases, infectious diseases, and for in vitro diagnostic applications and detecting biological molecules. The half-antibodies include at least two chimeric molecules A and B, each has a polypeptide domain characteristic of a variable domain of a heavy chain or of a light chain of an antibody, and a nucleotide domain, the nucleotide domain of A and that of B being capable of pairing into a double stranded structure. Biologically active nucleic sequences can be grafted onto these chimeric molecules to prevent the expression of target genes in the interior of a human or non-human mammalian cell. | 04-25-2013 |
