20120283447 | METHOD FOR PRODUCING NANOPARTICLES - Provided is a method for producing a nanoparticle. Provided especially is, in the method for producing a nanoparticle to separate a diketopyrrolopyrrole pigment, a method for separating an α-type diketopyrrolopyrrole pigment nanoparticle having high crystallinity by carrying out separation of the diketopyrrolopyrrole pigment and crystal type transformation to the α-type with substantially a single step. The α-type diketopyrrolopyrrole pigment nanoparticle is separated by mixing a diketopyrrolopyrrole pigment solution having the diketopyrrolopyrrole pigment dissolved in a solvent and an alcohol solvent containing an alcohol compound solvent in a thin film fluid formed between at least two processing surfaces | 11-08-2012 |
20130172575 | Pyrrolopyrrole derivatives, their manufacture and use - The present invention relates to compounds of the formula I | 07-04-2013 |
20130211100 | Method to Generate Novel Bioactive Molecules - The present invention describes a method to generate new chemical entities (NCEs) that have well-defined activities such as, but not limited to, anti-bacterial, antifungal and anthelmintic effects. The NCEs are generated through adaptive evolution of one microbe (the producer) against another organism or cell type (the target). The producer is made to compete against the target over time by co-culturing the two together and serially passing the producer organism until the producer adaptively evolves by synthesizing an NCE(s) that inhibits growth of or kills the target. The molecular structure of the chemical entity (or entities) is then clucidated using tools from genomics, molecular biology, computational biology, analytical chemistry, organic chemistry and related fields. | 08-15-2013 |
