Graft Polymer UK Ltd posted this:Project: Innovative pilot production modified compounds by PE125 standard for multifunctional applications.Producing PE125 using GRAFTALEN™ MP-UHHD. Consumer properties, which should be taken into consideration: 1) The unique toughness of the material (the highest rate of all known polymers), namely, Over 160 kJ/m2 2) High abrasion resistance 3) Low friction coefficient (self-lubricating) 4) High resistance to chemically aggressive reagents (media) 5) High creep resistance (geometric stability) Ordinary way - This type of process is quite expensive. Production of PE125, in compounding with bimodal PE100, from 8 to 45% of supermolecular polyethylene is injected, reaching dispersion by multiple compounding (4 stages) in an extruder cascade (XXXXX technology). GRAFTALEN™ MP-UHHD (alloy) is a MELT-PROCESSABLE concentrate of UHMWPE on an HDPE matrix. As HDPE, you can choose the most affordable HDPE (pipe) grade. To obtain polyethylene according to the standards PE125 (with a minimum strength indicator MRS> 13.8-14 MPa, in comparison PE100 has MRS only 10 MPa), a significant improvement in the resistance against hydrostatic pressure is required. For a conventional bimodal HDPE, this indicator is difficult to achieve, since it directly correlates with the impact strength/density indicators and with simple extrapolation, it turns out that the required indicator for PE125 simply does not reach the bimodal HDPE matrix. Another problem - the difficulty in maintaining the geometric stability of the pipe (the thickness at the top of the pipe is often less than at the bottom) due to the sagging effect (the phenomenon of the gravitational flow of a polymer melt). This phenomenon is more pronounced for thick-walled pipes. The specific blend of HDPE with UHMWPE allows solving these problems above.

INESC TEC posted this:a single-stage, bidirectional and high-frequency isolated power conversion systemACDC Cube is a single-stage, bidirectional and high-frequency isolated power conversion system. ACDC Cube also uses a novel control method to do the interface between the Alternate Current (AC) distribution networks and a battery pack, or other Direct Current (DC) sources/loads, delivering higher power quality in a compact design. ACDC Cube has lower total volume and weight, increased durability and equivalent reliability when compared with a standard solution such as the voltage source converter plus dual active bridge. Due to its innovative features, ACDC Cube is especially suitable for applications where the size of the power conversion system is critical.

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:Power supply system controlled from internet for devices connected to a lanNowadays there are devices that allow the control of devices connected to a network from the own network. The classical method to access them from a different network is the redirection of the corresponding TCP or UDP connections to local networks from the border router. The redirection requires a high level of expertise in communications to be performed. Another strategy that is often used is the creation of VPN (virtual private network). This technique allows the control of access but does not allow connections to be discriminated or the management of power supply. The proposed system allows you to control the person and the moment to access as well as the free access. The modification of these constrains can be performed in the course of an access session. In addition, the system allows the control of power supply of the device you want access to. The interface is very friendly and does not require continuous changes in the configuration of the router. The system has a local database access control and validation can be delegated to other servers using protocol validation like LDAP, IMAP, POP3, etc.

It is useful for the connection of a distributed generation system to a bipolar DC grid. For these applications, the proposed topology is a solution with sufficient guarantees of reliability, quality and performance. The converter circuit is very simple, it includes three inductors, four capacitors, two diodes and a power switch as a switching device.

Universidad de Alcalá-OTRI posted this:Risk management of the effects of solar activity: Device and procedure of obtaining in real time and high resolution, the Local Geomagnetic Disturbance at middle latitudes.The research team specialized in Space Meteorology within the Space Research Group of the University of Alcalá, has developed a device and procedure that, based on the measurement of the local geomagnetic field, is able to estimate the magnetic disturbance component associated to solar activity at middle latitudes. The determination of the magnetic disturbance component is especially relevant in cases of sporadic but explosive solar phenomena. From the perspective of the actual user, the present invention constitutes an essential element in the risk management of the effects of solar activity on vulnerable technologies, both ground-based and satellite-based (electric power, rail transport, terrestrial and positioning navigation systems, radio and satellite communication systems ...), increasing the capacities of public administrations, civil protection and emergencies and the companies themselves, in order to prepare a successful strategy for adverse conditions related to the solar activity. The group is looking for collaboration and/or commercial agreements with the Central Administration, Civil Protection, Critical Infrastructure, Electric Power companies, Rail Network, Oil pipelines companies, Gas Pipelines companies, Insurance firms, etc...
