Novel acoustic wave device and filter for its use in high frequency applications An acoustic wave device with one or more dielectric compensating layers that compensates the spurious signals by substantially temperature-independent nonlinearities occurring within the device has been developed. A direct application of this device has been the development of a novel acoustic filter. Partners to further develop the system and/or to establish commercial agreements with technical cooperation are sought.

Ultrasonic capillary reactor with temperature control and homogeneous vibration The Photochemistry and Semiconductor Electrochemistry (GFES) research group of the University of Alicante has developed an ultrasonically-enhanced capillary reactor which achieves homogeneous, efficient and temperature-controlled multiphase flow. The reactor features a capillary tube in a helicoidal probe that homogenizes the acoustic field generated without the appearance of longitudinal nodes and antinodes. Continuous and/or oscillatory reactions including crystallization phenomena are enabled, allowing the handling of solids and/or the improvement of heterogeneous mixtures in capillary tubes of variable diameter and length with optimum temperature control. Therefore, this reactor provides an advantage in flow chemistry and process intensification which is common in the pharmaceutical industry, fine chemistry, and in sonochemistry. The invention is protected by a patent application. The research group has a prototype on a laboratory scale. Companies interested in the commercial exploitation of this technology are sought through patent licensing agreements or technical cooperation agreements (R&D Projects).

Vibroacoustic spectrometry system for the non-destructive analysis of materials The research group "Radiation and Sensing Group" of the University of Alcalá presents a system of non-destructive analysis of materials and structures, by spectral study of the indirect vibroacoustic excitations of the materials analyzed. By means of this system it is possible to perform in situ the analysis of materials and structures without previous treatments, solving with that the need to use coupling liquids that the current ultrasonic based systems currently use. The group seeks to reach licensing agreements, collaboration agreements or commercial agreements with technical assistance, with companies from the agrofood, pharmacy, construction, ceramics, wood, cork and other materials sectors.

Acoustic propagation model and location systems for underwater environments GEINTRA, a research group from the Department of Electronics of the University of Alcalá, provides a model for studying the acoustic propagation in underwater environments. This model is useful for communications and positioning systems. The proposed model provides the channel response for the usual environmental phenomena. The model simulate how these phenomena affect a particular acoustic signal, and therefore, the performance of an underwater system based on acoustic signals can be evaluated previously to its deployment. The model has been tested for the case of underwater localization systems. GEINTRA is looking for companies working in telecommunications and IT sectors or performing works related to exact science and physics to achieve technical cooperation agreements.

Vibration-assisted ball burnishing: A solution for Surface enhancement through acoustoplasticity An innovative system to modify the surface integrity, i.e. surface texture and roughness, hardness and residual stress, of previously milled workpieces has been developed. The system can be easily integrated in real manufacturing environments, but should be tested with that aim. Partners to further develop the system and/or to establish commercial agreements along with technical cooperation are sought.

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.
