New chemical method makes it easier to extract pollutant pest control compounds from water

By | Biomedicine and Health, Chemistry | No Comments

Researchers from the Department of Analytical Chemistry and the Institute of Materials Science (ICMUV) of the University of Valencia (UV) have developed a method for the detection in water of PFRs (organophosphate flame retardants), compounds used in pest control that cause serious health and environmental problems due to their accumulation.

Researchers patent method to remove excess nitrate from water using rice straw

By | Chemistry | No Comments

The MINTOTA research group of the University of Valencia, led by Pilar Campins, professor of Analytical Chemistry; the DREMAP group of the Polytechnic University of Valencia and the University of Genoa have patented a method to remove the nitrate residue present in the water cycle using rice straw. Active silica is obtained from the controlled incineration of rice straw, which when modified has the capacity to absorb between 30 and 98% of the nitrates present in water. Read More

Scientific literature on oxidative reactions analysed

By | Chemistry | No Comments

The ASYMCAT research group, from the Department of Organic Chemistry of the University of Valencia (UV), has gathered in a review article all the information on asymmetric Mannich oxidative reactions, a set of chemical reactions that make it possible to obtain relevant compounds in the design of a broad set of drugs. The review, which has been published in the journal Advanced Synthesis & Catalysis (ASC), describes three methodologies used to transform amines – a type of organic chemical compounds derived from ammonia – into the corresponding reaction products, chiral β-aminocarbonyl compounds.

Scientists synthesise a material capable of degrading nerve agents in water

By | Chemistry | One Comment

A team from the Institute of Molecular Science (ICMol) of the University of Valencia has succeeded in synthesising a new porous material that enables and guides the degradation of compounds analogous to nerve agents used in chemical warfare. This material will make it possible to capture and degrade this type of compounds that until now could not be eliminated. The work has been published in magazine Chem. Read More

New study helps characterise the fusion of metals

Identifying the melting curve of a dense material is a challenge for science. Researchers from the Institute of Materials Science (ICMUV) of the University of Valencia have determined the relationship between the melting temperature of Niobium (Nb) and the applied pressure. The study has been published in the journal Nature Communications Materials. Read More

Researchers patent a kit to detect chemical submission drug GHB with the naked eye

By | Chemistry | No Comments

The MODeLiC (Organic Materials for Controlled Detection and Release) research team led by Ana María Costero, Professor of Organic Chemistry at the University of Valencia (UV), has developed a system with colorimetric sensors that change colour when there is γ-hydroxybutyric acid (GHB) in a beverage. GHB is a colourless, odourless compound with a slightly salty taste that when ingested overrides the will of the person. The research patented by the UV provides as a novelty the safety in the detection of this substance in alcoholic beverages and soft drinks. Read More
