Korea Institute of Energy Research posted this:Apparatus for producing silicon nanocrystals based on inductively coupled plasma.Researchers at the Korea Institute of Energy Research have developed a new apparatus for producing silicon nanocrystals based on inductively coupled plasma. Silicon nanocrystals have been widely investigated for several years because of their many interesting properties and potential use in several applications. Recently, silicon nanocrystals have been used in solar cells and light emitting device (LEDs). Silicon is an environmentally friendly material and is utilised for various applications in the field of electronic materials. The field of silicon nanocrystal production has grown enormously of late, in response to the observation of quantum confinement in porous silicon. Silicon is already widely used in the semiconductor industry, in large part because of its nontoxic properties and abundance, being the second most abundant element in the earth’s crust. Due to the high capacity of silicon paired with its relatively environmentally friendly properties it is an ideal material for use as a replacement to more commonly used environmentally costly materials. The common process of producing silicon nanocrystals can be classified into three distinct areas: solid-state reaction, liquid state reaction, and vapour state reaction. The solid-state reaction is the process whereby a thin film of SiO2, Si3N4 or the like containing excess Silicon (Si) is formed and subjected to heat treatment to enable the condensation of silicon and subsequent formation of silicon nanocrystals in a SiO2, Si3N4 or SiC matrix. In the liquid state reaction, silicon nanocrystals are prepared via a chemical reaction of silicon compounds, this is done through the application of variant methods, for example the high-temperature supercritical method. In the vapour state reaction, silicon nanocrystals are prepared by passing a silane compound gas through a high energy region such as laser or plasma. In the case of all three traditional silicon nanocrystals reaction methods (solid, liquid and gas) the process incurs significant cost due to the substantial need for heat energy and expensive deposition equipment. What’s more, in the liquid State reaction issues arise due to the severe difficulty in controlling particle size, which in turn leads to poor crystallinity quality. The vapour state reaction incurs further issues due to the extreme use of energy resulting in aggregated nanocrystals and the formation of secondary particles. To overcome the inherent issues of solid, liquid and vapour silicon nanocrystal reactions non-thermal plasma, such as inductively coupled plasma (IPC) has begun to be used. However, the conventional ICP-based apparatus has limitations and can result in issues pertaining to the management of the particle size of silicon nanocrystals, as well as extending reaction time and deteriorating silicon nanocrystal quality. To combat the aforementioned limitations in silicon nanocrystal production a new apparatus method has been designed, which can minimise plasma diffusion inside the reactor during production using ICP to improve the particle size characteristics and quality of the silicon nanocrystals.

Universidad de Alcalá-OTRI posted this:Intelligent regulation system of pedestrian crossings by monitoring the waiting areas and adaptive traffic light controlThe research group Intelligent Vehicles and Traffic Technologies of the Automation Department of the University of Alcalá has developed a system that allows the intelligent control of the opening and closing times of a traffic light that governs a pedestrian crossing, especially in urban areas. It is a road safety system that ensures that pedestrian traffic at pedestrian crossings is carried out safely, while optimizing the opening and closing times of traffic lights, achieving an improvement in traffic flow in urban areas. For this purpose, the monitoring of waiting areas for pedestrian crossings is carried out by means of a stereoscopic vision system with infrared illumination. The images provided by the stereoscopic vision system are processed by a computer, obtaining information regarding the presence of pedestrians in the waiting areas. This information is used to act on a traffic light that controls the pedestrian crossing. The group is looking for licensing agreements, technical cooperation agreements, manufacturing agreements and commercial agreements with technical assistance with companies in the sector of transport infrastructure and traffic safety as well as public institutions, such as municipalities and councils.

UNIVERSIDAD DE ALICANTE posted this:Production of briquettes for energy recovery of furniture waste with polyurethane foamsThe Research Group "Waste, energy, environment and nanotechnology" (WEEN) from the University of Alicante has developed a new compact material and a production process of briquettes of furniture waste. This process makes it possible to carry out the management and the energy recovery of this waste, avoiding the environmental problems associated with its landfilling and also making it easier to transport, handle and store. The briquettes obtained, show physicochemical characteristics similar to the conventional and they have a high energy density being able to be used as fuel for thermal power plants or industrial boilers. Companies in the waste treatment sector and the furniture industry that are interested in commercial exploitation of this technology through licensing agreements and / or technical cooperation are sought.

Moreover it doesn't cause boiler corrosion. Consequently it improves boiler thermal efficiency and fuel combustion effectiveness. That means lower costs of heating. It also modifies soot to be biodegradable, prevents releasing soot-related pollutions and isn't harmful to human health.
UNIVERSIDAD DE ALICANTE posted this:Noble metal-free ceria-based diesel soot combustion catalyst, suitable for gas purification in Diesel engine exhaustsThe developed catalyst does not use Pt, which leads to a cheaper product. The resulting catalyst shows equal or even better performance as Pt catalysts. Following the patented procedure of synthesis, the catalyst produced has a lower particle size. This leads to higher surface per particle and therefore, a better ratio yield when interacting in oxidation reactions, leading to a higher oxygen production rate.

Furthermore, the sintered ceramic substrate guarantees superior adhesion and resistance to fracture under high mechanical loads. The fabricated temperature sensitive diamond surface comprises well adhered ohmic contacts deposited on the backside of the dielectric ceramic substrate. This configuration prevents interaction between the temperature sensitive surface and the surrounding environment which is essential for biochemical devices applications. Furthermore, the planar geometry of the disclosed thermistor maximizes the contact region between the temperature sensitive surface and any solid flat surface on which it is placed. In this way, improved response times are obtained comparing to traditional round shaped thermistors.
