New 'Artificial Leaf' That Converts Carbon Dioxide Into Fuel

Scientists have created an “artificial leaf” to fight climate change by inexpensively converting harmful carbon dioxide (CO2) into a useful alternative fuel. The new technology, outlined in a paper published on November 4, 2019, in the journal Nature Energy, was inspired by the way plants use energy from sunlight to turn carbon dioxide into food. “We call it an artificial leaf because it mimics real leaves and the process of photosynthesis,” said Yimin Wu, an engineering professor at the University of Waterloo who led the research. “A leaf produces glucose and oxygen. We produce methanol and oxygen.” Making methanol from carbon dioxide, the primary contributor to global warming, would both reduce greenhouse gas emissions and provide a substitute for the fossil fuels that create them. The key to the process is a cheap, optimized red powder called cuprous oxide. An hour-long chemical reaction creates the engineered red powder that is the key to new technology to tur...

Alternate Building Materials Used in The Construction Industry

PC: theconstructor.org Alternate building materials are those which can be used economically by replacing the conventional building materials. Alternate building materials are made from waste products and thus they minimize environmental pollution. These alternate building materials can be used when they meet their respective specifications in the code of practice. Here are some novel construction materials and technology, with some briefly discussed: Aluminum Bitumen Materials Soil Conditioning Agents Tempered Glass Crumb Rubber Fiber Reinforced Polymer Glass Fiber Reinforced Plastics Bamboo reinforced plastics Ferro-cement Polyester Fibers ALUMINIUM sound-proof-aluminium-construction. PC: theconstructor.org More than 3000 commercialized applications. 35 percent aluminum produced is used in construction. Non-Corrosive. High durability and low maintenance. Can be alloyed. Ductile and malleable. Aesthetically attractive. Applications of Aluminum In...

Personality of the Week: Mr Andrew Kyeremanteng Anokye

Mr Anokye, MATESA PTW For this week, our Personality Dialogue dial falls on a stalwart of the Department, Mr Andrew Kyeremanteng Anokye , a level 300 Materials Engineering student. He has great interest in Writing and is specially interested in Foundry Technology. Enjoy the 'ride' with him. Who is Mr Andrew Anokye?  Mr Anokye is a Christian gentleman who believes that as humans we have the greatness within to do more! What was your experience like in secondary school? Secondary school was a great place to be. I enjoyed every bit of my stay in PRESEC-Legon, where I chalked some successes. It was not just a good experience, but a great one. Materials Engineering. Were you given the programme or you really wanted to do it? What informed your decision if you chose it?  I wanted to be a Civil Engineer. My Uncle inspired me and that was my dream program. I was given Materials Engineering and at the beginning, the interest for the program wasn't there. I developed ...

Be A Survivor -- A Poem By F. Agyemang

Many across the globe are bearing the brunt of Covid19. Some who haven't experienced it can't really imagine its consequences on people and economies. Let us thus relieve ourselves of the stress with this exhilarating poetic piece by @cocajuana_pens You can call me Covid I'm more dangerous than conflict I have no limit And I kill without mercy Cos I have no vaccine Just don't dare me I might end your destiny I'm so wicked! But you can avoid me Stay at home Give a distance And do no hommies For instance If you have to sneeze or cough Just cover it off Don't do it raw Else it'll be an issue So kindly use a tissue Hand washing should be regular That's the normal routine Do it with soap under running water Even if you haven't eaten Wondering how to keep clean? Use a hand sanitizer Just like many diseases I know I won't last forever A vaccine will be made And I will be slayed Until then, you have to be a survivor ...

Vibranium - The Wonder of Wakanda

Black Panther wearing Vibranium suit. PC: ucf.edu If you've ever thought that the Vibranium metal used in the Black Panther movie is a real material, you're possibly mistaken. What is Vibranium? Sourced from a meteorite that landed in Wakanda many centuries ago, Vibranium provides the superpower in the main character’s suit, absorbing energy and redistributing it. Vibranium (/vaɪˈbreɪniəm/) is a fictional metal appearing in American comic books published by Marvel Comics, noted for its extraordinary abilities to absorb, store, and release large amounts of kinetic energy. Mined only in Wakanda, the metal is associated with Black Panther, who wears a suit of vibranium, and with Captain America, who bears a vibranium-steel alloy shield which has never been reproduced. Real-world Material In 2016, Hyperloop Transportation Technologies developed a real-world smart composite material that they named Vibranium. The lightweight carbon fiber material for the Hyperloop ...

The 'thinking metal': Shape Memory Alloy

Nitinol wires. PC: Wikpedia By Francis Agyemang, Member of the Editorial Team, MATESA KNUST We are the intelligent metal alloys !!! Yes! People prefer to call us shape memory alloys and it is the name we well deserve. We never forget our shape when thermal or mechanical load is exerted on us. Once the load is removed, we regain our pre-deformed shape. Our thermal deformation is very unique, unlike other metals, we deform under low temperatures and regain our shapes upon heating. Our effect (shape memory effect) was first discovered in an alloy of gold and cadmium (AuCd) by Swedish physicist Arne Olander in 1932. 2D view of nitinol's crystalline structure during cooling/heating cycle The two most prevalent smart alloys are copper-aluminium-nickel (CuAlNi) and nickel-titanium ( Nitinol). Though we have many uses and potential applications, we are commonly used in mending broken bones and making of dental braces. A nitinol paperclip bent and recovered aft...

WHAT MINDSET HAVE YOU?--By Isaac Asiedu

As Henry Ford said, ‘‘W hether you think you can or you think you can’t, you’re right ’’ . Whatever your mindset is, it affect s  you. Your mindset is the lens through which you perceive the world. And th is lens affect s  how you live and the choices you make every day. The quality of your life is defined by the quality of your mindset. Your life can never get any better than your mindset. Your mind is a powerful thing and the stories you tell yourself and the things you believe about yourself can either prevent change from happening or allow new skills to blossom. According to Carol Dweck, a researcher at Stanford University, there are two types of mindset and the difference between these two mindsets and how they impact our performance are explained below : The first mindset is the fixed mindset .   S tudents with this mindset believe that their basic abilities, their intelligence, their talents are just fixed traits. They have a certain amount and that is that, and th...

The Natural Polymer That Controls Life - DNA!

Some life-forms on earth. PC: Micro [5 min read] In today's post on MATESA TODAY , we want to learn about a natural polymer (giant molecule) that controls all life-forms on Earth - in plants, animals, micro-organisms, etc. This wonderful material carries the instructions that are associated with the transmission of genetic information: the shape of your nose, the colour of your eye, people's height, their skin colour, etc.  This publication gives us some basic insight into  DNA . Sounds quite biochemical, but it has got the Materials Science aspect too - Polymers; though materials scientists primarily deal with synthetic polymers. But we usually take inspiration from nature to do new stuff, more technically, develop novel products. After all, we call it genetic material ! BASIC TERMS DEFINED Polymer means "many parts" and designates a large molecule made up of smaller repeating units. Monomer is a molecule that combines with other molecules of the same ...
