The technology concerns planar optical antennas composed of thin metal films and dielectric materials for the efficient direction of the light emitted by light sources, such as fluorescent molecules and bio-markers. They consist of a reflector layer, adjacent to the substrate, and a director, semi-reflective, between which the emitter is positioned, integrated into a homogeneous dielectric layer.

We developed an hybrid organic-inorganic composite consisting of a 2D perovskite and a copolymer. At room temperature the composite is highly transparent in the visible region with transmittance > 90%. At higher temperatures, the movement of the polymer chains releases the precursors, allowing the perovskite formation, which results in a colored film. The color changes according to the ‘n’ value of the PVK. PVK with n=1 starts coloring at 70°C, achieving a ∆Tmax = 91.5% at 510 nm.
The invention is a synthetic method to prepare colloidal nanomaterials of V-VI-VII semiconductors that do not contain toxic elements. This is the first method for the synthesis of mixed anion nanomaterials without toxic elements at large, which permitted to obtain, among others, bismuth chalcohalide nanocrystals that are arguably considered as one of main candidates to be the next big thing for light energy conversion.
The prototype uses soil moisture sensors which, through a measurement of dielectric permittivity, estimate the soil moisture based on which irrigation is started through relay-controlled solenoid valve. The system was developed using Open Source technologies. Specifically, for the hardware components, a small sized board computer Raspberry PI 3B + was used together with a 4G LTE Wi-Fi router and a Modbus rs485 / USB converter.
The Q-PLL is a nonlinear circuit which can maintain a locked state when forced by two incommensurate frequencies.
The locked state is a third frequency parametrically selected among those prescribed by the theory of three-frequency resonances in dynamical systems.
In particular, the locked frequency forms a three-frequency resonance with the frequencies of the quasi- periodic input and is closely related to the pitch perception of complex sound in humans.
Recently, it has been demonstrated that Raman spectroscopy can play a fundamental role in assisting the work of the anatomopathologist by allowing classification of oncological samples with practically 100% accuracy in oncological diagnosis.
Polymer development is approaching to a new stage of advancement in which new functionalities especially in combination with conductive polymers and nanomaterials are more effective. In this context the study of new composites is the key to enable the development of disruptive technologies as additive manufacturing. Increasing electrical conductivity open the way to a new class of objects to be prototyped rapidly at low cost with a high level of customization.
Electrochromism is an optoelectronic characteristic of particular interest because it can be exploited in the creation of technologies such as smart windows (Smart Windows) to promote energy efficiency, automotive, sensor or visualization devices. Electrochromic materials change their optoelectronic characteristics, showing different colors depending on the applied electric field.
The technology refers to a system for the safety and control of the mobility of vehicles, pedestrians, and mass transport users, in conventional and advanced contexts and is suitable for use as an infrastructure for the production/sharing of information and data, aimed at monitoring and intervention in critical areas by offering specific functions concerning the detection of potentially dangerous situations or the optimization of resources.
uManager is a management game designed to foster the development of young students' entrepreneurial skills and abilities. The game offers the opportunity to manage a tourist village, stimulating the skills of decision making and problem-solving in a simulated scenario adhering to the real one. uManager is suitable for use in the classroom or at a distance, in formal and informal contexts.
VOLIS is an online platform that contains various tests for assessing Italian Sign Language (LIS) comprehension skills in signing children, from 4 to 11 years of age. The consequences of some difficulties such as deafness, cognitive impairments and autism spectrum disorder may affect learning, social interaction and broad communicative skills. The use of LIS may support children that have difficulties in acquiring and using a using spoken languages.
