Centre Technology Transfer CITTRU posted this:Carbon composites based on bacterial biomass for manufacturing of electrode materialsThe subject of the offer is a method of manufacturing of carbon-based composites for electrode materials. These composites are built of electrode active phase nanoparticles (e.g. metallic or metal oxides) and a carbon matrix obtained from bacterial biomass. Living organisms serve both as the component capable to capture the nanoparticles, and as a source of biocarbon support providing high dispersion and stabilization of nanoparticles, as well as high electrical conductivity of the material. Application: electrocatalytic active electrode materials, e.g. in ORR reactions; energy storage (supercapacitors).

Institut Català d'Investigació Química (ICIQ) posted this:Photochemical metal-free method of amination of C-H bondsA new method for the metal-free amination of C-H bonds has been developed. The method uses readily available reagents (iodine, trilfuoromethylsuylfonamide, diacetoxyiodobenzene) and light to insert a sulfonamide moiety into a C-H bond. the method has been successfully used in the preparation of various APIs (memantine, rasagiline, sertraline). The method takes place in mild conditions and allows avoiding the use of transition metal catalysis and multiple-steps procedures. Partners are sought for the joint development of commercial applications of the method.

University of Huelva posted this:New method for manufacturing magnetic cores by powder metallurgyMagnetic cores in amorphous state are usually produced by placing together very thin amorphous ribbons from a material obtained by the melt-spinning technique. The new patented method produces the amorphous material by mechanical alloying, a traditional process in the powder metallurgy field. This technique allows a higher control on the amorphisation process and the properties of the amorphous obtained powders. These powders are then consolidated by the very quick process known as Electrical Resistance Sintering (also Electrical Discharge Consolidation/Sintering can be used). A final amorphous material, without the typical frontier between ribbons of melt spinned materials, which clearly affect properties, is obtained.
University of Vigo posted this:Lateral connection system by removable clamps for I or H profilesThe presented system allows detachable lateral connections, at right angles, type ‘cross beam to column flange’ of I and H standard profiles made of steel. The system uses standard mounting clamps without previous specific machining operations (as may be welding or drilling).
University of Vigo posted this:Removable and reconfigurable system for corner connection of square tube profilesThis removable connection system can be adapted to the size of the section, by adjusting the length of the connecting bolts, using the same flanges. Is usable for a wide range of standard profiles, which avoids the need for a flange size for each profile section.
University of Vigo posted this:Removable system for continuous connection of square tube profilesThe removable system allows mounting on each profile separately, joining then in continuity with plates at the head of each of the flanges. The use of anti-buckling clamps prevents local buckling of the walls of the profiles, associated with tightening of flanges. Flanges have nerves to reduce stresses. The same flanges are valid for connecting different sized sections of square tube profiles.

The treatment is applied using an electrochemical deposition technique, allowing for the development of conformal coatings, irrespective of design complexity. Layer thicknesses are low (10-100nm) but resistance in corrosive marine environments indicate corrosion rates comparable to technologies currently employed by the aerospace and automotive industries. Corrosion rates are reduced by between 103 and 105 times, dependant on the nature of the porous coating. Tests on metallic coatings indicated a reduction in corrosion rates of approximately 103-104 while tests on ceramic coatings indicated a reduction in corrosion rates of approximately 105. By applying the hybrid treatment as a sealant treatment onto a porous wear resistant coating, concerns regarding the effect of mechanical damage are dramatically reduced. In addition, surface roughness levels are similar to electropolished finishes.
Brunel University London posted this:Magnesium Alloys with Improved CastabilityMagnesium alloys are lightweight and so provide the best solution for reducing weight in the transport sector. However increasing the use of these alloys to replace steel has been hampered by their lack of ductility and low yield strength. This is due to the large grain structure, defects and inter‑metallic particles formed during casting. New magnesium alloys produced using a novel Magnesium Boride grain refiner have a much finer structure with fewer defects, resulting in improved ductility and strength in addition to reduced defects during casting and ease of casting complex shapes.
Brunel University London posted this:Zagblade: Reduction of aero acoustic pollution by introducing novel serrated trailing edgesAn aerofoil blade design that reduces trailing edge noise by means of a saw-tooth serration filled with a porous material. The serration and porous material work constructively with each other to significantly improve the aero-acoustic performance. An optimal choice of the porous materials has been identified, where it can achieve broadband noise reduction whilst completely suppressing the vortex shedding tone. This new device is more industrially-ready than the conventional “add-on” type serration due to its superior structural integrity. In addition it produces an aerodynamic performance similar to that of the baseline aerofoil. Applicable to a wide range from applications from drones, UAVs, aircraft engines, wind turbines and fan blades.
