CIDETEC have been working with EGOKI HANDLES on developing new anti-adhesive finishes for metal parts for a number of different applications.
The aim of the project has been to achieve product enhancement, specifically to add a transparent and anti-adhesive protective coating to the TIRADORES EGOKI (EGOKI HANDLES) company range of decorative finishes for their metal.
From a technical perspective, two alternatives were initially put forward for obtaining organic protective coatings for zamac (Zn+Al+Mg+Cu alloy) handles: firstly, organic coatings by means of electropolymerisation and secondly, the application of a protective varnish with anti-adhesive characteristics, the latter being precisely the one which gave the desired results.
The key aspects worked on were the optimum adhesion of the varnish to the handle, getting good end properties for the coating and devising a method for the application which was useable on an industrial scale. To this end, new families of products were studied and which were based on special organic-inorganic hybrid varnishes with anti-adhesive properties, and which have recently appeared on the German market.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
