King’s Hub: Videos You Should Watch

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?

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

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 […]

History of Arabic Alchemy

alc

While reading Jim Al-Khalili’s book “Pathfinders: The Golden Age of Arabic Science” it became apparent that scientific collaboration is essential to achieve meaningful progress. Great advances were made in the medical profession during the Golden Age. The Golden Age occurred during the Abbasid rule which was between the 8th century and the 12th century CE. […]

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 […]

Exploring Epigenetics: DNA methylation and cancer

We all know the environments physical effects upon an organism are apparent, but have you ever considered what effect it has upon us on a genetic level. This is a difficult concept that has intrigued many scientists and encouraged them research into it further. It is only recently that our basis of knowledge and the technological advancements […]

Nanomedicine – What are the risks?

There are many arguments against nanomedicine due to the issue of toxicity. Elements  at a microscopic level have different properties than they have at their standard conditions and every nano particle is completely unique so they each have different properties. These leads to the possibility of the nanoparticles having a serious effect on our health. […]

The Real Meaning of Science with Liz Bonnin

On Thursday 6th November, I had the pleasure of interviewing BBC Television presenter Liz Bonnin. Liz has presented many TV programmes over her career, from BBC Bang Goes the Theory since it first aired in July of 2009 and Operation Snow Tiger to specials like the BBC Horizon Series to BBC Stargazing Live. She’s used her […]

Science Bites

sci bites cover final big

For a few months now, I’ve been working on my eBook – Science Bites. Tomorrow it reaches the Amazon Kindle Store for £1.51. The idea behind the eBook was to make science fun and interesting – by using small, manageable pieces of information.  The eBook is about 180 pages long and covers topics from life […]

Particle Size Optimisation of Sand to Improve Water Treatment Efficiency

Fig1 (1)

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
