From fundamental science to product: a bottom-up approach to sunscreen development

Posted on 5. April, 2018.

Ultraviolet (UV) radiation from the Sun is categorised as UVC (100–280 nm), UVB (280–315 nm) and UVA (315–400 nm). Stratospheric ozone prevents any significant amount of highly destructive UVC radiation from reaching the Earth’s surface, as well as absorbing a significant portion of UVB radiation.

Free for 24 hours - Problems and resolutions in dealing with waste disposable paper cups

Posted on 21. March, 2018.

Disposable paper cups used for serving coffee, tea and other drinks contain high quality virgin cellulose fibre board (95 wt%) combined with a thin internal polyethylene (PE) coating (5 wt%). They are typically employed where washing and sanitising of reusable cups is awkward, such as in hospitals, in the entertainment and transportation sectors, and for occasional use by large numbers of people in short time intervals which makes reusable cup service practically impossible.

The scientific dating of standing buildings

Posted on 12. March, 2018.

Over recent years, our understanding of building history has been transformed by the use of scientific dating techniques. This has been particularly significant for the innumerable modest buildings of Britain – houses, barns, mills, etc., that are described as ‘vernacular’.

Mathematical models of microbial growth and metabolism: a whole-organism perspective

Posted on 7. March, 2018.

Life on Earth can be divided into several kingdoms, with the prokaryote domains of the Archaea and the Bacteria standing out by dint of their vast metabolic diversity and versatility which is belied by the paltry morphological variation encountered in these domains.

Moonlighting proteins – nature’s Swiss army knives

Posted on 22. February, 2018.

The human body is an amazingly complex machine with billions of cells that work together to perform a vast number of biochemical processes, each requiring hundreds or thousands of protein machines to serve as the structures and to synthesise the components, convert food to the chemical energy, break down old components, regulate all these processes and coordinate with other components, cells, and organs.

Photosynthesis, pigment–protein complexes and electronic energy transport: simple models for complicated processes

Posted on 18. December, 2017.

Essentially all the accessible energy for life in the Earth’s biosphere is made available through the process of photosynthesis, the conversion of light energy from the Sun into storable chemical energy for metabolism. The process itself has been the subject of remarkable evolution throughout Earth’s history.
