Summary of the technology
The most remarkable advantages provided by this technology are:
• Rapidity of the metallic nanoparticle synthetic method, as it consists of only one step.
• Efficiency, since size, shape and concentration of nanoparticles are controlled, as well as, their production in organic or inorganic soluble solution.
• Reduced production costs, as high temperatures are required by other alternative laser ablation methods.
Description of the tech for sale
Different procedures for the synthesis and covering of inert metallic nanoparticles have been developed during the two last decades, like suspension of metallic and silicon nanoparticles, synthesis by organic solvent addition or several laser ablation methods. Nevertheless, currently used methods show disadvantages, such as they consist of several steps, need high temperatures (500-1000 ºC) for the synthesis, etc. Thus, an increase of production costs is caused. Researchers from University of Valencia have developed a new procedure for the synthesis of inert metallic nanoparticles with only one step.
Specifications
Method for obtaining stable colloid of inert metal nanoparticles in a single step comprising the laser ablation of a solid target submerged in a liquid medium containing metal salts. The nanoparticles synthesised using the aforementioned method have a controlled morphology and size and a high SPR absorbance intensity in a narrow wavelength range. This method lets production of nanoparticles in a rapid way and at low temperature, controlling size, shape and concentration of nanoparticles.

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 ..

Method for producing nanocorundumResearchers from Geology Department of University of Valencia have developed a novel method for producing corundum of low crystallinity (nanocorundum) using natural or synthetic commodities in solid state, without pre-treatment. The process of the invention makes it possible to obtain a product with a nanocrystalline nature, composed of tabular- or plate-shaped primary nanoparticles in porous microcrystalline aggregates, which facilitates the subsequent disaggregation process thereof into powders that have an immediate application as ultra-fine abrasives and as loads (or fillers) in plastics or other types of materials. This characteristic represents a significant advantage of the product of the invention, since compact corundum is a hard, difficult-to-grind material.Universitat de València posted this:
New method for the production of metallic oxides with spinel structureThis procedure is faster, with lower energy consumption and generates purer spinels than known methods for spinel production. With this invention, it’s possible to provide new methods for obtaining spinels or other mixed oxides with a higher processability and versatility than those existing to date, allowing also for obtaining new spinels and removing the need for extremely costly phases in time or energy, including milling or heating at temperatures up to 1200ºC.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.
