Non-stick surface technology

By Hilda Kafui Nuworku [3min read] Non-stick is a surface engineered to reduce the ability of other materials to stick to it. Non-stick is often used to refer to surfaces coated with Polytetrafluroethylene (PTFE),  but in the 21st century other coatings have been marked as non-stick, such as anodized aluminum,  ceramics, cast iron, carbon steel and many others. Cast iron, carbon steel, cast aluminium and steel cookware may be seasoned by applying fat to the surface and heating to polymerize the fat. This produces a dry hard smooth, hydrophobic coating, which is non-stick when food is in it. Polytetrafluroethylene is a synthetic fluoropolymer or tetrafluoroethylene that has numerous applications. Its well known brand is Teflon® , by Chemours,  a polymer company. PTFE molecular structure. PC: susbtech.com Properties of PTFE: It's a fluorocarbon solid, with a high molecular weight. It's hydrophobic due to the high electronegativity of Fluorine. It ...

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 ...

THE WAIT

Illustration. Credit: HIOS The past they say hunts you down . But to get someone who overlooks all the past and says, ''Hey you deserve another shot'', has always been a one in a million event. We met in the weirdest of ways but we have grown to become the best of friends. If anyone had told me things would have grown this fast between us, I wouldn't have believed. Today I stare at your pictures and I can literally smell you. ''Am I getting mad?'', I ask myself. Maybe, no; probably yes. But if I would go mad because of the person who although I needed a new start due to my past transgressions, yet believed in me, then I wouldn't think twice about it. I guess the light I see in her is what she sees in me. We are taking things slow, not rushing a thing; trusting Your timing, not pushing when we need to pull--step by step, growth by growth--not  missing even a single nano-detail of the process. Am I mad to wait till you are ready?  For I...

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...
