Fingerprints left at crime scenes are one of the tools used to incriminate or eliminate suspects. However, they’re not always visible, and investigators will often rely on chemical techniques in order to visualise them. There are a large number of techniques that can be used to do this; here, we take a look at four of the most common.

This Week in Chemistry – Partial Lead Water Pipe Replacement Risks, and All About that (Super)base

July 24th, 2016|

Here’s the weekly summary of both new chemistry research and studies that have been in the news. This week features news on a new record holder for strongest base ever, why partial replacement of lead water pipes may be riskier than not replacing them at all, and more. As always, links to further articles and original research papers are provided below, as well as further studies of interest not included in the graphic.

Today in Chemistry History – The Trinity Nuclear Bomb Test

July 16th, 2016|

Today marks 71 years since the first nuclear weapon detonation. Codenamed ‘Trinity’ it was detonated on July 16, 1945, in the Jornada Del Muerto desert in New Mexico. This graphic takes a brief look at the device itself, and also at trinitite, the pale green glass left behind as a remnant of the test.

Anyone who’s studied chemistry will be overly familiar with titrations. It’s an analytical technique that can be used to find the concentration of a solution (the amount of a solute dissolved in it). I put this graphic together primarily to remind my A level students of some of the key aspects of titrations, but as well as being a handy guide for them, it’s a useful introduction to the technique for non-chemists too!
