Organization from European Union posted this Technology CallSeeking hyperbranched, non charged, short molecules/dendrimers able to be coupled to keratinous surfacesWe are seeking for molecules/compounds/materials which are chemically composed of two opposite parts (see Fig.). The first part of such molecules has a hyperbranched/dendrimer-like/fork shape. The second part (which is geometrically opposit to the first) is a moiety which will favour attachement. The attachment on the skin or hair surface could be generated by adhesion, covalent bonding, electrostatic attachment etc. For instance such latter moieity could react with free amines present on the hair fibers (more attachment points on the skin and hair could be considered, e.g. hydroxyl groups). Lactone groups are an example reported in literature of a reactive moiety which upon heat application can bound to the free amine of the hair. Once bounded to the skin/hair such molecules will work as molecular spacers. The molecules need to be neutrally charged, rigid, branched and have a low particle density (number of atoms in a physical volume). They will therefore decrease the interaction (e.g. Van der Walls attactions) between external particles (such as sand or dust) and the functionalized surface. Example: N-Glycans are an example of such molecular spacers and an example of desired geometrical structure. Glycan with 5 Mannose units for instance will occupy a Volume of 2.25 x 1.65 x 1.24nm with 162 atoms, which lead to a particle density of 35 x 10(^27) atoms/m^3. Such lower particle density will lead to a reduction of the Hamaker-interaction coeffiecint between the funcitonalized surface and an approaching particle. Such molecule will therefore lead to a decrease of the friction coefficient and adhesion forces.

Beiersdorf AG posted this Technology CallSeeking technologies to jellify fluids (water or oil) without using polymeric molecules or surfactant systems.The main goal is to find a technology to jellify a fluid without using macromolecules or concentrated surfactant systems. The fluid in question may be water or oils (eg. hydrocarbons, triglycerides, fatty acids and esters - mostly saturated). The concentration of the gelling agent should be below 5% w/w. (preferentially < 2% w/w).
ERTRAC Global Competitiveness Working Group posted this Technology CallSeeking research & innovation centres of excellence in advanced functional materialsIn the context of sustainable mobility, research on environmental sustainable lightweight solutions must be continued in an integrated, systemic approach taking into account the application-oriented development of novel material systems. We are seeking information from research centers-of-excellence capable of performing future material development respecting environmental sustainability and circular economy requirements, including: • Natural and bio-based materials as well as recyclable & recycled materials • Materials for energy storage • Materials alternatives to rare and high demand materials • Material repair, reuse and disposal and offering specific functionalities including, for example: • Conductive and piezoresistive polymers, • New surface and coating solutions e.g. for self-cleaning, self-healing or anti-corrosion, • Reversible adhesives and joints, • Materials for noise abatement and aesthetical improvements. Appropriate cost- and energy-efficient manufacturing and assembly strategies will need to be addressed.
