uacoopera posted this:Low Cost Minimum Quantity of Lubricant SystemA group of researchers from a Portuguese university has developed a system of "Minimal Quantity of Lubricants" fully functional and automated. The term MQL, "Minimal Quantity of Lubricant", refers to the use of a low lubricant flow (10 to 100 mL / hr) through a high pressure fluid (compressed air). This system is an alternative to most lubrication systems used in machining operations, with both economically and ecological level advantages, contributing to sustainable manufacturing. This system stands out for its optimal functioning, automation, low cost and good portability. It allows a good lubrication and a good cooling of the machined piece, dry chips, a cleaner desktop, thus ensuring a higher yield and environmental improvement.

DIT Hothouse posted this:iSeal: Advanced Surface Treatment for Protection against TribocorrosionThis invention is based on the application of a hybrid organic/inorganic treatment onto an exposed surface – either as a stand-alone treatment or as a sealant. 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.

The functionality is incorporated into the structure of the titania being protected thereby.
Universidad de Alicante posted this:New family of dyesThe main innovative aspects of this technology regarding current methods of synthesis are: • The indolizine dyes are obtained in one step from commercially available materials, unlike current procedures, which involve multiple steps. This is an advantage in the production process, as it reduces costs, increases the final yield and less waste is generated. • The procedure is based on a very simple treatment which produces indolizine dyes in yields higher than 70%. • The present invention does not require the use of inert atmosphere, dry solvents or physical activation (heat or radiation) to obtain the final product. • Unlike other methodologies for preparing indolizine dyes (requiring temperatures around 100°C), this process is carried out at room temperature and atmospheric pressure, which simplifies the method and decreases production costs. • This is an environmentally friendly technology because it does not use solvents such as dioxane, pyridine, chloroform or benzene, which are used in other methods and are characterized by their high toxicity and demonstrated carcinogenicity. • The selectivity of the reaction is very high. The indolizine dye is obtained with absolute control, obtaining a single isomer of the ten possible.
