King’s Hub: Videos You Should Watch

Posted Leave a commentPosted in Biology, blog, blogs, Chemistry, Environment, Health, Health Sciences, Mathematics, Physics

Here is a selection of short, fun and interesting videos recommended by the King’s Hub. There is something for every scientist, with maths, physics, biology and chemistry related content. Although they are great to watch purely as entertainment, the King’s Hub also loves these videos because they show the wonderful (and slightly weird) knowledge that science […]

How can we distribute electricity more efficiently?

Posted Leave a commentPosted in blog, Chemistry, Engineering, Physics

Magnesium diboride superconducting cables! A new superconducting prototype cable has been developed to aim to create superconducting transmission lines for improved efficiency and less of an environmental impact for the electricity grid. To meet future energy demands, all the electricity grids throughout Europe will need to be upgraded and expanded for higher transmission capacity. For […]

Carbyne: Officially the strongest material in the world

Posted Leave a commentPosted in Chemistry, Engineering, Nanotechnology, Physics

Scientists in Vienna have successfully created a stable form of carbyne, the world’s strongest material. Carbyne is a linear acetylenic carbon – an infinitely long carbon chain. It can be considered as a one-dimensional allotrope of carbon. Carbyne has a chemical structure with alternating single and triple bonds: (−C≡C−)n. This structure of carbon gives an […]

Chemistry and Light

Light and Chemistry are more linked than you might think. There are lots of reactions which give out light as a product. We use chemistry and light in communication, electronics, medicine and entertainment. Photochemists are working for a brighter and cleaner future – essentially trying to harness the sunlight, converting it into useful energy and […]

Particle Size Optimisation of Sand to Improve Water Treatment Efficiency

Posted 1 CommentPosted in Chemistry, Issue 14

More efficient treatment methods must be developed for ensuring the future availability of drinking water. The purpose of this project was to determine how particle size composition can be optimized to improve the performance of sand as a natural, inexpensive, sustainable water filtration media.
Calibrated sieves were used to selectively remove specific particle size fractions from all-purpose sand. Permeation times, together with pH and calcium concentrations of filtered water samples were used to prove that the water filtration rate of sand can be increased by 65% by removing the <150 micron particle size fraction (11.3% by weight), while maintaining pH buffering performance.

Paramagnetic fluids optimization of the chemical synthesis of magnetite ferrofluids

Posted Leave a commentPosted in Chemistry

Abstract Ferrofluids are paramagnetic liquids. The fluid is made up from a stable suspension of magnetic nanoparticles. This study investigates the synthesis of magnetite based ferrofluids with focus on the parameters of the precipitation of magnetite particles using iron(II), iron(III) and ammonium ions. Under the hypothesis that the precipitation speed and pH value had major […]
