Universitat Politècnica de Catalunya - UPC posted this:Environmental Quality Assessment of contaminated soilsEnvironmental quality of soils is determined using analytical chemistry methods, with expensive and sophisticated equipment. Toxicity assays provide a global response regarding the danger of contaminated soil to living organisms. However bioassays are based in lengthy experimental procedures (between 7 and 28 days) to provide reliable results. Normalized soil assays use different species of earthworms and collembola that must be grown and maintained in specialized facilities. Partners to further develop the technology and/or to establish commercial agreements along with technical cooperation are sought.

The combination of these three reagents allows the construction of the sensor on any conductive surface, avoiding the electro polymerization of the indicator. The resulting sensor allows to measure MG2 + in any type of samples, without the need to add organic salts, additives or organic solvents. The quantification of Mg2 + is done directly by incubating the sensor in the sample containing the analyte, resulting in a modification of the amperometric signal proportional to its concentration. This method has many applications especially in health and biomedical sector since Mg2 + participates in such important activities as neuronal, neuromuscular transmission, or regulation of blood pressure and plays a key role in various pathologies such as vascular and migraines headache. The group is looking for companies in the agro-food, bio-sanitary and environmental sectors, with the aim of reaching technical collaboration agreements, commercial agreements or patent licenses.

The process is carried out in the absence or presence of some solvent, during the process of the current invention, temperature may be or may be not used as catalyst, in the process of the current invention the reaction may be or may not be catalyzed by the presence of a catalyst (acid or base), the resultant products can be produced and separated in an easy way, in the process of the current invention starting from pyridinic alcohols the resultant ethenediols can be produced by a single step reaction. The pyridinemethanol derivatives used as starting compounds, do not oxidize as easily and their handling is easier than that of other compounds. The products produced with etheneidol parts can be used as antioxidants due to their capacity to act as free radicals scavengers.

The particles have an irregular shape and variable size for filling columns of different diameter and length. The adsorbent has sufficient hardness for avoiding a particle collapse. The material does not rot, is re-generable and ecological. In the present invention the preparation of the adsorbent, its pre-activation, carbonization and application to eliminate the color of textile wastewater is disclosed.; The color elimination from textile wastewater, as well as decrease of salts, total suspended solids, chemical oxygen demand (COD) and total organic carbon (TOC), is carried out passing the textile wastewater through a column filled with the prepared adsorbent. In batch systems metals dissolved in water can be eliminated.

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..

By merging these properties in one platform, these nanobeads provide a faster and less expensive method for the separation and enrichment of specific proteins, often present in biological media in very low concentrations, compared to conventional methods such as metal-ion affinity chromatography.
