Yissum - Research Development Company of the Hebrew University posted this:A novel approach to suppression of reproductive performance of the Mediterranean Fruit Fly (Ceratitis capitata) and other major pests of agricultureThe Sterile Insect Technique (SIT) to control insect pests is based on their mass-production in dedicated facilities, separation and sterilization of males and their periodic release, in order to compete with wild-type males, and essentially impose female sterility. Their are several problems associated with this procedure: (1) Females tend to soon overcome imposed monogamy, and remate again with males available at that time. Based on research funded by the ISF and the Chief Scientists Fund of the Ministry of Agriculture, we have devised a novel transgenic procedure to prevent or reduce subsequent re-mating of the females in the field, and suppress egg development, which is normally induced by mating. Such transgenic males produce a modified "Sex Peptide", as a component of their seminal fluid, which imposes long-term non-receptivity on females subsequent to initial mating. (2) The second problem is that the current practice of irradiation-imposed sterilization of males is debilitating and reduces their field performance. It is also logistically time-consuming and costly. This situation requires the release of a large overabundance of males (in the case of the Medfly, twice-weekly throughout the year). We propose that irradiation be replaced by genetic sterility and have several suggestion of how this might be approached. The genetic sterility we propose would be incorporated with the persistent modified Sex Peptide, and combined, these two male-specific transgenes would significantly augment the SIT.

UNIVERSIDAD DE ALICANTE posted this:Holographic sensor for detection of adulterants in essential oilsThe research group of Holography and Optical Processing of the University of Alicante has developed a holographic technique for the detection of adulterants in essential oils. This technique is able to detect different types of adulterants qualitatively. In addition, a quantitative measurement of the degree of adulteration of an essential oil can also be performed by means of pre-calibration of the sensor for a particular adulterant. The sensor could be miniaturized and manufactured at a low cost compared to traditional methods of analysis such as gas chromatography and high performance liquid chromatography. The sensor can be used by unqualified personnel.

UATEC - Unidade de Transferência de Tecnologia posted this:Ohmic heating reactor for chemical synthesis, the method and its applicationsIn ohmic heating electrical energy is dissipated in heat with a very high efficiency (electrodes in contact with the reaction medium), resulting in fast and uniform heating and in the increase of charged species movement. As in the case of the heating with microwave radiation, electrical energy is transformed into thermal energy. However, on contrary of heating with microwave radiation (penetration depth of microwave radiation in absorbing media is limited) the penetration depth is virtually unlimited and the extent of heating is regulated only by the spatial uniformity of electrical conductivity throughout the reaction medium and the time spent in the ohmic reactor. Thus, the direct scaling of the ohmic heating for the pilot or industrial scale shouldn’t have the limitations presented by microwave radiation heating. It is also possible to reduce reaction times and increase the energy efficiency of chemical reactions

Substances which were extracted from these plants act both as reducer of silver and gold ions and stabilizing agent of forming silver and gold nanodispersion, preventing them from agglomeration and inhibiting their growth, so that the resulting particle size does not exceed 100 nm.
University of Vigo posted this:Procedure for the extraction of biosurfactants contained in corn steep liquorsNowadays, most of the pharmaceutical and cosmetic products in the market contain chemically synthesized surfactants in its composition. In many cases, these surfactants are the same as those used in regular cleanup activities. In order to get more natural and biocompatible products, it would be interesting to include natural surfactants instead of chemical surfactants in the preparation of these pharmaceutical and cosmetic products. These biosurfactants are also present in the formulation of greener nanoparticles, replacing the chemical surfactants currently used in the preparation thereof. Most biosurfactants have antimicrobial activity, which would improve the properties of certain nanoparticles, as well as many pharmaceutical and cosmetic products. The main disadvantage of biosurfactants industrial production is related to the high cost compared to chemically synthesized surfactant production. The solution proposed by the Chemical Engineering research group at the University of Vigo, is the development of eco-friendly simple extraction of biosurfactant from a corn wet-milling industry byproduct, such as corn wash liquors, better known as "corn steep liquor (CSL)", which could compete in terms of cost production with its chemical counterparts.

This is the first method to date for deprotonation-free, direct cupration of fluoroform, a longly sought after reaction.
