Consejo Superior de Investigaciones Científicas posted this:Biocompatible self-generating cell stimulatorCSIC through the Instituto de Microelectrónica de Barcelona - Centro Nacional de Microelectrónica, has developed a device based on nanogenerators for electrical cells stimulation without the need of electrodes or bulky devices. The device is biocompatible and, among its multiple applications, is able to actuate in medical prostheses as an enhancer of cellular growth and proliferation, which permits an early lesion recovery (such as a fracture or wound). Industrial partners dedicated to the development of medical devices for cells stimulation, in particular, focused onto therapeutic treatments of non-healing wounds, are being sought to collaborate through a patent license agreement.
NDI Foundation posted this:NEW FLUORINATED CARBON MATERIALS FOR FUEL CELLS AND BATTERIESOur project is the solution for sorting out rechargeable batteries enchanted anode and fuel cells Proton Exchange Membranes (PEM) efficiency issues. We propose to start mass production and sales of the products based on the new technology of Soft Fluorination for Carbon Materials and products derived by this technology. Our product is globally prospective and ready for industrial use. The product is targeted to the following segments of clients: - fuel cells producers - proton exchange membranes (PEM); - energy storage systems - batteries and super-capacitors electrodes; - Super-acid Catalysts for numerous uses; - Fillers for fluorinated resins; - Biologically indifferent sorbents (e.g. for blood purification); - Hydro-isolation of resins adhesion of construction composite materials and pigments. As so far in the fuel still not realized their potential as a cost efficient, environmentally friendly and productive in converting available chemical energy into electric energy.
University of Huelva posted this:New power generation electric systemThe proposed system is characterized by the following aspects which make it unique: 1- The system is built from a number of PEM fuel cells, supplied by al least one hydrogen source. Each module include a monitoring and control subsystem, so it is possible to activate/deactivate module induividually. 2- Each module can supply a different power value. 3- The monitoring and control subsystem receives electrical signal from each modules like stack voltage, stack current and cell voltage. 4- The monitoring and control system has two levels: the first level aims to control each module (local control) and the second level is responsible for coordinate local controller. 5- The monitoring and control system is on-line accessible. 6- The control and monitoring system distributes homogeneously the operating hours between the modules when the power demand is lower than the maximum power. 7- Each module has a oxygenation/cooling subsystem which supplies oxygen to cathide and air for refrigerate the stack. 8- Each module has a hydrogen subsystem wich is the responsible for hydrogen delivery to stack at ambient pressure. 9- The hydrogen subsystem include a hydrogen purge line. 10- The Electric Power Generation System includes a simulator to reproduce the performance ogf the whole subsystem.

Furthermore, the sintered ceramic substrate guarantees superior adhesion and resistance to fracture under high mechanical loads. The fabricated temperature sensitive diamond surface comprises well adhered ohmic contacts deposited on the backside of the dielectric ceramic substrate. This configuration prevents interaction between the temperature sensitive surface and the surrounding environment which is essential for biochemical devices applications. Furthermore, the planar geometry of the disclosed thermistor maximizes the contact region between the temperature sensitive surface and any solid flat surface on which it is placed. In this way, improved response times are obtained comparing to traditional round shaped thermistors.

New designs are enabled since this "Liquid-Carrier for Hydrogen" is stored in tanks of any shape. The economics of this system have been validated by DOE and is among the least expensive methods of high-volume hydrogen storage. When loaded with hydrogen from renewable sources this technology delivers a complete green solution since the carbon portions of the molecules are completely re-used. With a well-to-wheels efficiency comparable to gasoline or EVs, this technology can deliver world-class efficiency.
