King Faisal University’s inventions attracted the attention of international companies participating in the International Exhibition of Inventions (IEI), which was held in Switzerland, during the period from April 17 to 21, with the participation of more than 1,000 inventions from 45 different countries.
The university explained that the gold medal-winning invention represented a new technology for generating electrical energy from environmentally friendly wastewater, and included the use of wastewater containing urea as fuel in urea fuel cells, which holds great potential to meet the growing demand for energy, as it is a new source. And sustainable renewable energy.
She pointed out that this invention can play an important role in addressing energy and environmental challenges by providing an effective and environmentally friendly solution to convert urea waste into valuable energy resources, as new nanostructured materials have been manufactured and characterized, and the results of this project can easily be transferred to applied research. Through the direct production of the university’s new type of high-efficiency electro-oxidation catalyst, high-efficiency catalysts can be produced in the laboratory for urea fuel cells. The project will give insight into energy awareness and its global importance, especially in the Kingdom of Saudi Arabia.
The silver medal-winning invention was based on creating an environmentally friendly natural material to stabilize sand dunes using innovative cellulose extract from palm waste, which effectively prevents the movement of sand resulting from the wind and improves stability. These sustainable solutions reduce the environmental impact, reuse agricultural waste and provide an alternative to traditional methods. The composite materials were mixed with sand to increase stability and prevent movement caused by wind.
The technology for treating the Coronavirus using sustainable and environmentally friendly aerosols also won a silver medal, which was that treating the Coronavirus using sustainable and environmentally friendly aerosols aims to develop environmentally friendly nanometer sprays that can be applied in closed spaces and have the ability to bond with Coronavirus particles. on its surface, and then; These aerosols can be disposed of using methods such as electrostatic attraction or adsorption, with the aim of reducing respiratory distress syndromes and preventing coronavirus infection in indoor spaces. The use of sustainable and environmentally friendly aerosols is of paramount importance in the fight against coronavirus and provides targeted and effective solutions while minimizing environmental damage.
The university stated that a new technology for using the digital compass for initial access to users in millimeter-wave cellular networks won the silver medal, as the patent included the use of a digital compass in millimeter-wave wireless communications technology for the first time, allowing the caller connected to the network to share his location with others for the purpose of Connecting them to the network in order to overcome the problem of lack of connection that millimeter communications suffer from in the event of indirect communication between the communication tower and the caller.
The invention of a double-headed tool to close wounds after surgical operations won a bronze medal, as laparoscopic surgery is one of the most common operations, and it is very important to close wounds in the abdominal wall after completing the surgical intervention in order to avoid any possible complications. A double-headed tool was invented to close wounds. After surgical operations, this tool is designed to close wounds accurately, quickly and safely, in order to prevent surgical complications in wounds, God Almighty willing.
The innovation of a multi-purpose energy system based on the conversion of biomass by flexible gas technology to the field of electrical generation also won a bronze medal, specifically in the field of power generation resulting from solid fuel gas with heating and cooling applications, where waste heat from the HCCI engine is used to implement applications. Multiple cooling in a combined exhaust refrigeration cycle and a dual-range refrigeration cycle, in addition to process heating and energy production by turbine.
