The present invention relates to a device that enables the in-situ deposition of materials at different growth angles from a single evaporation source. The oblique-angle growth of thin-film materials facilitated by this device is based on physical vapor deposition (PVD) processes and is achieved by gradually varying the orientation angle of the substrate surface relative to the material flow from the evaporation source. This device allows for the modification of the growth structure of various materials at the nanoscale and microscale, opening the possibility of studying the influence of these microstructures on the mechanical, optical, thermal, electrochemical, and other properties of thin-film materials.
This device for dynamic testing of seismic isolator prototypes in a real-world environment allows for the application of uniaxial shear, compression, or a combination of both loads. The device enables controlled vertical compression and lateral deformation of the seismic isolator specimens under test. The configuration of the device’s components allows for automated testing, subjecting the specimens to successive cycles of varying or increasing amplitude in both directions until limit states are reached without the need to reposition the specimens between tests. Through the controlled application of forces and deformations via vertical compression and horizontal tension-compression mechanisms, the seismic isolator specimens are loaded and deformed in both directions, generating the actual stress conditions under service conditions as would occur during a real seismic event in a structure.
A novel device for testing structural elements with varying characteristics. The device’s component configuration allows for the application of bending moments to evaluate behavior under rotation, shear forces in one or two directions to assess behavior under lateral displacement, vertical compressive forces to represent the structure’s gravitational loads, or a combination of these three types of time-varying stresses. The device features a lateral load application mechanism supported by a reaction frame and a vertical load application mechanism also supported by the same reaction frame. These mechanisms enable the simultaneous and controlled vertical and lateral deformation of the structural element specimens under test, through the inclusion of hydraulic actuators and electrohydraulic servo valves for precise control of the hydraulic flow supplied to the device by a hydraulic power system.
Technology developed for the efficient separation of corpuscles and groups of living cells, such as pancreatic islets that can be recovered from the pancreas of cadaveric donors or animals such as pigs.
A technology is available that allows the production of green hydrogen from wastewater using low-cost photoelectrochemical processes. Unlike conventional systems, the water used for hydrogen production does not require pretreatment. Instead, the wastewater is treated with oxidizing agents, which convert the water into hydrogen and oxygen. The water then passes through a device where oxidation-reduction reactions take place, converting it into gas. The gases are then separated by another device.
