Seater of The Week: Mr Abdul Latif Abubakar

Meet our Sports Personality of the Week, Mr Abdul-Latif Abubakar: a hard working gentleman and the current MATESA electoral commissioner. Mr.Latif - SOTW Who is Mr.Latif Abubakar?(Relationship status:dating, broken up, gnashing) Well, this question is a bit difficult to answer since day in and day out, people change and grow. But I will say Abdul Latif Abubakar is a young hard working gentleman who believes in self-discipline. Ha-ha, sure I’m dating. Share with us your experience in secondary school.What is the worst you ever did in school you really regret. I attended T.I. Ahmadiyya Senior High School, Kumasi (Real Amass). My SHS life was very fun and nice. I will say, I didn’t really struggle over there; and because I was a very hard working and discipline guy, everyone liked me. Oh not really (on the worst thing) but I think my only regret was forcing some mates to adhere to the school rules and regulations since I was a prefect. Why did you choose KNUST over t...

Researchers Discover New Useful Nanostructure for Composite Material

Biwu Ma, professor of chemistry and biochemistry  Florida State University researchers have discovered a novel structure for organic-inorganic hybrid materials that shows potential for more efficient technologies. Professor of Chemistry and Biochemistry, Biwu Ma, and his team have published a new study in the journal Science Advances, that explains how they created a hollow nanostructure for metal halide perovskites that would allow the material to emit a highly efficient blue light. Metal halide perovskites are materials that have shown great potential for photon-related technologies such as light-emitting diodes and lasers, but scientists have still been working to make them more efficient and effective. "The fabrication of new-generation color displays and solid-state lighting requires luminescent materials and devices of the three primary colors: red, green and blue (RGB)," Ma said. "Although multiple ways of color tuning have been demonstrated for perov...

History of Man As Determined by The Prevailing Materials Technology of a Particular Era

Compiled by Abena Osei-Anane   [5 min read] The ages of materials technology - PC: pininterest.cl Earth’s beginnings can be traced back 4.5 billion years ago, but human evolution only counts for a tiny speck of its history. The pre-history period where there was no documentation of human activities roughly dates from about 2-5 million years ago to 600BC and is categorised in three archaeological periods: the Stone Age, Bronze Age and Iron Age . These periods are characterised by the prevailing Materials Technology present at a particular time. STONE AGE Getty images The Stone Age was the first age and the longest, from 30,000BC to 3,000BC. This era was marked by the use of stones to make tools and weapons . During the paleolithic period, early humans lived in small caves and were mostly hunters. They used basic stone tools as well as stone axes for hunting birds and other wild animals. They were the first to leave behind art by carving small figurines from stones,...

The Quality of Locally-manufactured Cornmill Grinding Plates

Corn mill A KNUST research has revealed people who consume corn-related foods risk contracting all kinds of cancers According to the research, the locally manufactured machine used to grind the corn into dough food wears off faster into the dry maize, thus contaminating it. A study by two lead researchers at the Kwame Nkrumah University of Science and Technology (KNUST) has revealed that consumers of corn-related foods risk contracting all kinds of cancers. The research was undertaken by Prof. Kwofie, who is the Dean of the Faculty of Mechanical and Chemical Engineering (former) of the College of Engineering, and Dr. Anthony Andrews (now Professor) , the Head of Department (former)  for Materials Engineering . The study found that the metals used for the milling plates usually wear off when the food products are being grinded. This, the study said, opens consumers to the risk of contracting cancer, since the metals contain 'iron overloads' which are poisonous. ...

Sports Seater of The Week: Raphael Kwasi Sarfo Gyebi

Ralph Gyebi (SOTW) Meet Ralph on Sports Seat today, a fine gentleman and prospective metallurgist. Certainly the crush of many MATESA ladies (Hahaha).  Please tell us about yourself. (Relationship status: Gnashing, dating broken up, crushing, etc). Well, I'm Raphael Kwasi Sarfo Gyebi, a 3rd year Metallurgical engineering student. An old boy of Mfantsipim school. I love sports and arts. I find humour in almost anything. And I'm single, hahaha. Share with us your experience in secondary school. Secondary school was fun, having attended a boys school. The learning and church service and craziness that came with entertainment made SHS worthwhile. In the long run, it built our persona in every aspect of our lives, Mentally, emotionally, and spiritually hei, devotion on weekdays and morning and evening service on Sunday no be joke. Metallurgical Engineering, were you given the programme or you chose it? I chose it as my last choice and It was given to me. But I...

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 ...

Material Manufacturing from Particles Takes a Giant Step Forward

A scanning electron micrograph shows a fishnet structure formed by nanocellulose that has bound 1.15 micrometers of silica particles together. Credit: Bruno Mattos / Aalto University Tiny fibrils extracted from plants have been getting a lot of attention for their strength. These nanomaterials have shown great promise in outperforming plastics, and even replacing them. A team led by Aalto University has now shown another remarkable property of nanocelluloses: their strong binding properties to form new materials with any particle. Cohesion, the ability to keep things together, from the scale of nanoparticles to building sites is inherent to these nanofibrils, which can act as mortar to a nearly infinite type of particles as described in the study. The ability of nanocelluloses to bring together particles into cohesive materials is at the root of the study that links decades of research into nanoscience towards manufacturing. The research reveals the universality of coh...

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...
