Centre Technology Transfer CITTRU posted this:Method of isolation and purification of xanthophylls from diatom cultureXanthophylls, with their antioxidant, anticancer, anti-inflammatory and neuroprotective properties, found important applications in food and nutrition, cosmetic and environmental industries, as well as pharmacy and medicine. Diadinoxanthin (Ddx) and diatoxanthin (Dtx) are two pigments that belong to xanthophylls family. The availability of Ddx and Dtx on the market is low and up to date limited as they are sold exclusively in small quantities at extremely high prices to be used as HPLC calibration standards. The solution of the above mentioned problems is the 5-step method for the isolation and purification of Ddx and Dtx developed at the Jagiellonian University..

Universitat de València posted this:Sample collection devices of atmospheric pollutants with high performanceThe main advantages provided by the invention are: Simplicity and reproducibility in the synthesis of the new compound, due to one step synthesis process with simultaneous addition of all reagents. It isn’t necessary the removal of CDs, and it hasn’t intermediate compounds between silica and CDs. It allows the access to VOCs without any post-treatment. Adaptability of the compound to the requirements of each sample collection devices, adjusting the grain size by milling and using appropriate sieves. Procedure cleaner, safer and more economic, since it reduces the generation of toxic waste and the risk of contamination of workers. Reduce analysis time since desorption of pollutants retained in the sample collection devices can be thermal. Retention of pollutants is more independent of environmental conditions than commercial devices.

xrqtc posted this:Polymorphism Prediction in Crystal Systems of Technological InterestCurrent polymorphism studies are being carried out using one of the following three alternatives: atom-atom potentials, DFT (Density Functional Theory) calculations and ad-hoc potentials. However, all of them have serious disadvantatges. 1) with software that uses atom-atom potentials: Advantages: fast and capable of working with large molecules. Disadvantages: the "blind tests" carried out by the "Cambridge Crystallographic Data Centre" are giving a 50% maximum success in the predictions. 2) with software based on DFT calculations: Advantages: good results Disadvantages: they are computationally very slow, so they are only used for very simple molecules compared with drug molecules. In addition, they have errors predicting van der Waals interactions and weak hydrogen bridges if not corrected empirically. 3) with software using ad hoc potentials for each molecule obtained from systematic exploration of the surface potential of intermolecular interactions: Advantages: efficient and faster. Disadvantages: some potentials should be calculated for each molecule studied, which are complex and slow, and is not general. The approach presented here is new and unique because the potential Pixel has never been used before for drawing polymorphic predictions and it has shown to present the advantages of all the alternatives combined. This is the first research group which has brought the potential Pixel to this level of calculation. The potential calculations and the applicability of the methode based on pixels have the same quality that the sophisticated ab initio based potential calculations. Besides, this is much faster than DFT (Functional-Based Theory)-based and ad hoc potentials ..

The technique also permits the quantitative analysis of almost all the congeners of dioxins and furans (more than 130 different compounds), not only the main 17 toxic compounds. The technique could be applied to different fields: gaseous emissions from the combustion, characterization of hazardous and toxic wastes, determination in food and feed, determination in sewage sludges and other organic fertilizers, determination in other matrices such as tissues and blood, air, emission due to the traffic, paper, ink, hygienic materials, tobacco smoke, chimney soot, dust… Innovative aspects: − The know-how involves the ability to measure a very low concentration of dioxins (values close to picograms or femtograms). It does not depend on the precise equipment but the expertise in preparing properly the samples by means of a very sensitive and specific analytical method. − The technique also permits the quantitative analysis of almost all the congeners of dioxins and furans (more than 130 different compounds), not only the main 17 toxic compounds. − Nowadays, this methodology (standard one) is the only one available method to carry out reliable dioxin analyses.
