Synthetic and biologically-derived products produced using biomass produced by photobioreactors configured for mitigation of pollutants in flue gases

Certain embodiments and aspects of the present invention relate to photobioreactor apparatus designed to contain a liquid medium comprising at least one species of photosynthetic organisms therein, and to methods of using the photobioreactor apparatus as part of a production process for forming an organic molecule-containing product, such as a polymeric material and/or fuel-grade oil (e.g. biodiesel), from biomass produced in the photobioreactor apparatus. In certain embodiments, the disclosed organic molecule/polymer production systems and methods, photobioreactor apparatus, methods of using such apparatus, and/or gas treatment systems and methods provided herein can be utilized as part of an integrated combustion and polymer and/or fuel-grade oil (e.g. biodiesel) production method and system, wherein photosynthetic organisms utilized within the photobioreactor are used to at least partially remove certain pollutant compounds contained within combustion gases, e.g. CO2 and/or NOx, and are subsequently harvested from the photobioreactor, processed, and utilized as a source for generating polymers and/or organic molecule-containing products (e.g. fuel-grade oil (e.g. biodiesel)) and/or as a fuel source for a combustion device (e.g. an electric power plant generator and/or incinerator).

System and method for a transparent color image display utilizing fluorescence conversion of nano particles and molecules

A system and a method of a transparent color image display utilizing fluorescence conversion (FC) of nano-particles and molecules are disclosed. In one preferred embodiment, a color image display system consists of a light source equipped with two-dimensional scanning hardware and a FC display screen board. The FC display screen board consists of a transparent fluorescence display layer, a wavelength filtering coating, and an absorption substrate. In another preferred embodiment, two mechanisms of light excitation are utilized. One of the excitation mechanisms is up-conversion where excitation light wavelength is longer than fluorescence wavelength. The second mechanism is down-conversion where excitation wavelength is shorter than fluorescence wavelength. A host of preferred fluorescence materials for the FC screen are also disclosed. These materials fall into four categories: inorganic nanometer sized phosphors; organic molecules and dyes; semiconductor based nano particles; and organometallic molecules. These molecules or nano-particles are incorporated in the screen in such a way that allows the visible transparency of the screen. Additionally, a preferred fast light scanning system is disclosed. The preferred scanning system consists of dual-axes acousto-optic light deflector, signal processing and control circuits equipped with a close-loop image feedback to maintain position accuracy and pointing stability of the excitation beam.

Multiple-effect pollute-removing water purification agent and use method thereof

The invention relates to a multi-effect pollution removal purifying agent and a method for applying the same. The purifying agent is complexly formed by a strong oxidant, an effective adsorbent and an assistant medicament by a weight percentage of strong oxidant 10-80%, effective adsorbent 10-70% and assistant medicament 5-50%. The surface water treatment process of using multi-effect pollution removal purifying agent of the invention comparing with the common flocculants has the following advantages: effectively improving the turbidity removal ratio, increasing the flcos formation amount and alum blossom density for the difficult coagulated surface water, improving the deposition efficiency, oxidizing and removing the organic matters in the water, eliminating the chroma and odor caused by the pollution, increasing the effluent conventional indexes, obviously improving the indexes such as oxygen consumption and ammonia nitrogen, wherein the removal rate of oxygen consumption and ammonia nitrogen can reach 25-60%, the removal rate of small organic molecules, benzenes and phenols can reach more than 80%, playing an obvious roll for the algae inactivation of lake water and reservoir water which are serious eutrophic, improving the algae removal efficiency of the deposition and filtration technologies with an algae removal rate of 80-90%, improving the coagulation efficiency, reducing 20-30% of the common flocculant dosage, effectively adsorbing the codeposition heavy-metal ion. The adding equipment of the invention is easy and convenient to use with little investment and fast effect.

Superantibody synthesis and use in detection, prevention and treatment of disease

Superantibodies having enhanced autophilic, catalytic, and/or membrane-penetrating properties are prepared by affinity-based conjugation of a photoactivatable organic molecule to a target immunoglobulin. The photoactivatable organic molecule bears a chromophoric aromatic hydrocarbon moiety, which has affinity for the immunoglobulin. Upon photolysis, the organic molecule is covalently linked to the immunoglobulin. A preferred organic molecule is a peptide and a preferred aromatic hydrocarbon moiety is a tryptophan residue. The photoactivatable organic molecule need not bear a purine, pyrimidine or azido group to effect binding to the immunoglobulin and/or photoactivation. The superantibodies can enhance the potency and expand the targeting range of target antibodies. Autophilic superantibodies can promote apoptosis of target cells and/or enhance therapeutic efficacies in the treatment of patients with diseases or disorders responsive to antibody therapy. Exemplary of such diseases are atherosclerosis and cardiovascular disease. Membrane-penetrating superantibodies can prevent apoptosis by binding to intracellular anti-caspase signal proteins. Compositions containing the superantibodies, as well as methods of making and using them, are disclosed.
