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.

This technology particularly relates to a method of preparing an anionic binder in the form of nanosized powder after crosslinking. The prepared anomic binder exhibits enhanced durability to electrochemical reactions and enables the easy fabrication of electrodes.

UNIVERSIDAD DE ALICANTE posted this:Stand-alone system for the purification of brackish water directly powered by photovoltaic solar energyThe Applied Electrochemistry and Electrocatalysis Research Group at the University of Alicante has developed an Stand-alone system for the desalination and disinfection of water by Electrodialysis (ED) and the necessary water pre- and post-conditioning steps. The developed system is sustainable and environmentally-friendly being directly powered by a photovoltaic solar plant without using battery racks. This new system substantially decreases both the investment and maintenance costs by eliminating the batteries. Also, it can be adjusted to be used in water from very different sources like seawater, brackish water wells, wastewater treatment plants, industrial processes water, etc. being of particular interest for remote areas isolated from the electric grid. The Research Group has a demonstration Pilot Plant with the capacity to produce up to 1m3 of drinking water per day. The Group is looking for companies interested in the commercial exploitation of this technology through licensing agreements and/or technical cooperation.

Advantage of cooling the Photovoltaic System generating more power under high Global radiationSchwimmfähige Photovoltaikanlage / Floatable Photovoltaic System to produce Electric Energy using floatable Aluminum- plates in thermal contact with Photovoltaic Elements. Weather dependend heating of the Photovoltaic Elements will reduce their efficiency in producing Electric Energy. Cooling the Photovoltaic System (PV) down to receive Electric Power more effiently when exposed under high Global radiation. High Global Radiation (W/m²) could heat up PV e.g. to 60° C and result in a so called "Voltage drop". The Photovoltaic System combined in thermal contact with cooling elements could be used on air. Further Research on this matter is planned.
