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
Cracow University of Technology posted this:Suspension containing gold or silver nanoparticles or a mixture thereof and a production method thereofThe present invention relates to a process for the preparation of nanosilver and nanogold using an aqueous extract of dog rose, white grape and knotweed. 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.

Institute of Chemical Research of Catalonia posted this:New method to produce trifluoromethyl copper reagents useful in trifluoromethylation reactions from fluoroformThe trifluoromethyl copper derivative useful in trifluoromethylation reactions is prepared at room temperature from readily available and cheap reagents and in high yield, i.e. without the formation of side-products associated to the fast decomposition of the trifluoromethyl anion, that usually forms in processes involving the deprotonation of fluoroform. This is the first method to date for deprotonation-free, direct cupration of fluoroform, a longly sought after reaction.

RAMOT at Tel Aviv University Ltd. posted this:Plant endophytic fungi for crop protection and resistance to abiotic stressPlants contain numerous microorganisms, in particular fungi. They are collectively referred to endophytes. Endophytic fungi are beneficial for the hosting plant, therefore the co-existence from day 1. The advantages for the plants include growth enhancement, protection from pathogens and pests, ability to grow and reproduce in sub-optimal conditions such as water limiting conditions and sub or supra- optimal temperatures. During cultivation, important genes have been lost and scientist are trying to find genes in wild populations and add them back into cultivated plants. ICCI specializes in diseases of cereals. Work is done on isolation of disease resistance genes from wild relatives of wheat and introduction into cultivated wheat. We propose to complement the genetic efforts by producing disease resistance through the use of endophytic fungi; Similar to gene loss, we believe that essential microorganisms have been lost during cultivation. We will utilize the vast collection of seeds from wild relative of wheat and barley to identify hidden endophytes that contribute to plant disease resistance and survival in arid and warm climate. After identifying such endophytes in the wild plants, we will introduce the most beneficial species into cultivated wheat and barley. This approach has been already used successfully in pasture plants. Expected outcome: 1. Novel knowledge on the composition of endophytic species in wild grasses relatives of wheat 2. Patent of species with economical and agricultural potential 3. Development of pathogen-protection in wheat and barley 4. Development of climate sustainability in wheat and barley Project ID : 2-2013-719
