المملكة: Pictures | Rotation of coffee waste and fast car charging … research creations and sustainable solutions for “talent” students

“Today” monitored inspiring models of student ideas, which transformed the challenges into solutions, including innovations that contribute to the recycling of organic waste to generate electricity, the use of 3D printing to make environmentally friendly radioactive protectors, as well as innovative engineering designs that address the difficulties of charging electric cars in unconventional ways and research in cancerous tumors.
This came during the closing ceremony of the “Talent” research program in the engineering sciences, presented by the King Abdulaziz Foundation and his men for talent and creativity, “Talent” in partnership with King Abdulaziz University.

Gifted support

First of all, the director of the Innovation and Entrepreneurship Center at King Abdulaziz University d. Saud Wali that the university hosts this year 19 talented students from various cities of the Kingdom, participating in work on six advanced research paths, including renewable energy, electric cars, environmental sustainability, medical engineering, nuclear engineering, and biochemistry.
He added that these research programs come within the university’s efforts to empower the talented and provide a scientific environment incubating creativity and innovation, by harnessing the capabilities, overcoming all difficulties, and providing facilities and equipment, as well as specialized research cadres to embrace such programs in the various corridors of the university.
He pointed out that these initiatives come within the framework of the university’s vision to devote knowledge as a tool for development, and to enable young minds to contribute to facing national and global challenges through scientific research and technical innovation.

The student, Omar Al -Mitwalli, said in the first secondary stage: It is working on a research project aimed at developing radiation protectors used in hospitals and centers that are exposed to radiation in abundance, and it is a safe and more sustainable alternative to traditional lead condoms.
He stated that the materials currently used in the production of radiological condoms are largely dependent on the element of lead, which is a heavy and toxic substance and causes health damage, in addition to being high cost and difficult to get rid of them in a safe way.
He continued: My project focuses on the production of radioactive protectors using natural materials made with 3D printing technology, which makes them formed in different sizes, less expensive, lighter, in addition to being environmentally friendly.
He pointed out that the motivation behind the idea came from his personal experience with his father, who works as a doctor in orthopedics, adding: My father always has to wear heavy radiological protectors during the rays, and he told me about the extent of exhaustion he caused, and from here came the idea of developing a more comfortable and safe alternative.

Project development

He stated that he aspires to expand the scope of the use of this technique in the future, to include protective -covered condoms, used in radiology rooms, nuclear factories and other highly exposed environments, stressing that the project is still in its early stages, but it seeks to develop it in cooperation with researchers and specialists in the medical and engineering fields.
For his part, the student Badr Bukhari said, in the second secondary grade: The global problem of cancer is a defect in the “DNA”, or the “Epi-Henetics” in the cell, and it has few solutions, but there is difficult of them and there is harmful, and an example of the difficult laser, and the harmful is a chemical medicine and is called Doxorubicin “Dox”.
For his part, the student Badr Bukhari said, in the second secondary grade: The global problem of cancer is a defect in the “DNA”, or the “Epi-Henetics” in the cell, and it has few solutions, some of which are difficult and some are harmful, most notably a chemical drug called “dox”.

He pointed to the choice of the “sage plant” used in alternative medicine in abundance, because it is a useful herb, and the polar substances were extracted from them on 3 types of cancer, namely “colon, liver and breast”, and the experiment proved that the effect of the sage was equivalent to the impact of the Dox on cancer.
He continued: Our future goal is to make sure of its effectiveness by re -experiment more than once, and to try their effect on normal cells, and to know exactly what the extract that affected the cancer cells.
The student, Abdullah Melbari, indicated that he is working on an innovative project aimed at solving one of the most prominent obstacles facing electric car users, which is a problem of slow charging and limited to provide charging stations in public places, where it works to find wireless charging in the paths of rapid demand “Drive-thetru”, to convert it to an effective charging of electric cars, and that his project depends on a wireless magnetic field, installed in the floor The track, the car picked up and turns into an electrical energy stored in the battery while waiting.

Sustainable ideas

He said: One of the most important results of his research is to convert car waiting in paths in which it spends from 5 to 45 minutes, until a time to charge cars, where the car can be charged nearly 1 kilowatts in 10 minutes and it is sufficient to travel by the electric car a distance between 5 to 7 kilometers, depending on the type of car, which is a good achievement for a quick charging during the short stop.
The student “Hamza Baaboud” pointed out that his love for coffee led him to a research to exploit coffee waste in generating electricity, for sustainability and clean energy, as his project works to recycle coffee residue after its use, a substance that is consumed in huge quantities globally, where some statistics reach that the world produces about 50 million tons of coffee residue annually, while only 33% of them are recycled, which opens, which opens The way for innovative ideas to take advantage of them instead of throwing them.

He added that his idea is to use heat and humidity to stimulate coffee residue to produce electricity, especially since the resulting voltage was weak at room temperature, but it increased gradually with increased temperature, until it reached 5 volts at 200 degrees Celsius, which is a promising result.
He stressed that the project contributes to converting organic waste into a clean energy source, and reflects its commitment to contribute to achieving sustainable environmental development, thanking King Abdulaziz University for its full support during the project implementation period.
