Method for quantification of the speed of printing of continuous fibers in processes of near-field electrospinning and electrohydrodynamic jet printing for microfabrication The offered invention allows controlling the process of electrohydrodynamic (EHD) jet printing in which an ink is printed on a substrate as a continuous line or fiber, forming predesigned 2D patterns and 3D structures. This is also known as near-field electrospinning (NFES). The offered technology allows determining the speed at which the EHD ink jet approaches the substrate before it collects transforming into a printed fiber. The knowledge of its speed of approach is critical for controlling the process of printing and create high-resolution patterns and structures, and, ultimately, for ensuring the desired performance of the printed fibers (device). In this invention, the jet trajectory is oscillated electrostatically at a known frequency, resulting in a repeating printed pattern. The speed is obtained from macroscopic, easily quantifiable features of the printed pattern, such as width on a serpentine track (2D pattern), or diameter of a cylinder (3D structure). A patent is pending for this technology.

3D printing of continuous fibers for microfabrication, such as flexible electronics and biofabrication A versatile 3D printing technology is offered in which electrostatic control is used to form a continuous electrohydrodynamic ink jet and to precisely position it on a substrate forming a predefined pattern made of solid fiber with fiber diameter typically in the few-micron or submicron ranges. The technology uses electrostatic forces to deflect the trajectory of the fast-moving jet in its flight toward the substrate, in a time-varying fashion. This technology is capable of printing predefined 2D patterns and 3D microstructures with submicrometer resolution and unprecedented speed of up to 2000 fiber layers per second, resulting in total printing time of up to about 1 second per 3D structure. A patent is pending for this technology.

PLA/PP pure polymer or composite powder for 3D printing application: easy and cost-effective manufacturing with scale-up potential 1. Pure polymer and composite powders with scale-up manufacturing potential for powder-based 3D printing applications 2. Cheap, simple and straightforward manufacturing methodology 3. The proposed composite powder can easily be manufactured into composite filament for filament-based 3D printer. 4. No requirement of additional mixing or blending of filler materials with polymer, as the powder itself the blend of polymer and fillers. 5. The application of these nanocomposite powders will not only be limited to 3D printing applications but also can be used for cold-spray coating, extrusion mouldable composite materials processing where the dispersion of filler materials is challenging.

Kits for cell culture based on hydrogel coatings CSIC and Complutense University of Madrid have developed new kits for cell culture based on cytocompatible hydrogels coated onto stiff substrates. Due to the excellent adhesion of the hydrogel to these substrates is possible to have mechanically robust platforms, easy to handle as required in a cellular biology laboratory. These new kits have been successfully tested showing an excellent cellular proliferation on the surface of the hydrogel. Besides, this technology allows the detachment of a cell monolayer without the need of chemical or biological agents preserving the viability of cell harvesting. Industrial partners from the biotechnology with expertise in cell culture are being sought to collaborate through a patent license agreement. An offer for Patent Licensing

Photoinitiators for visible-light induced living polymerization A new class of photoinitiators of living polymerization induced by visible light has been developed and is made available for testing (under MTA) and/or licensing. The developed initiators trigger the curing of resins by irradiation with low-intensity visible light, while providing polymers with good control of chain length. In addition, through decomposition of the initator, the cured material presents a different colour than the uncured resin.

3D printer for the in-situ building of habitable modules with a raw mixture of binders and the soil of Mars A student of the University of Aveiro did the “spin-in” of an invention that started to be developed with the collaboration of teachers and investigators of several departments. The invention, that’s been arising interest in the business sector, locally and nationally, aims at the production of habitable modules using the soil in inhospitable locations, and it was specifically thought for Mars. The advantages of this process are the total automation, and it distinguishes itself from other solutions proposed until now for providing a closed construction, airtight, with total habitability, safe against cosmic radiation with other devices, and the possibility of holding distinctive functions. He University is looking for partners that may be interested in financing the development of this tool.

Zagblade: Reduction of aero acoustic pollution by introducing novel serrated trailing edges An 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.
