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

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

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.

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
