Off to @WykeCollege this afternoon to talk about the amazing #chemistry that goes on in Hull, and the opportunities for chemists & chemical engineers in the region 🧵🪡 #Careers
@ThisIsReckitt have their R&D headquarters in Hull, they make nurofen, detol, gaviscon and lots more
@CrodaSTEM manufacture lubricants, adhesives, skin care ingredients. You find one of their products in bottle lids, without it you’d struggle to open and close you drink container. crodasmartmaterials.com/en-gb/applicat…
Tronox manufacturer titanium dioxide used in sunscreen, paper whiteners and more
These companies, and more in the Humber create 1000s of jobs in the region and form the 2nd largest cluster of chemical industry in the UK. Together many of these companies have formed @ZC_Humberzerocarbonhumber.co.uk

Bad news, #COVID has reached chez Lorch, via the plague pits that are our schools.
Good news, I get to do some experiments with #LFTs & +ve samples
Experiment number 1, how does swabbing influence LFT results? 🧵 🪡 1/n
The left LFT was carried out as per instructions. I wasn’t sure if I could see a T line, so I immediately repeated the test & doubled the rotations up each nostril. & left the swab in buffer for 5 min. Now the T line (right) is clearly present 2/n
Whilst doing the 2nd test I noticed the T line on the 1st test was getting stronger. At 30min I wasn’t sure if I could see it, but after 2hrs it had developed into a faint but clear line. 3/n
Citizen-led sampling to monitor phosphate levels in canals and rivers using a simple paper microfluidic device 1/n chemrxiv.org/articles/prepr…
We (& that's the academic 'we' which means it was mostly done by PhD student @__SamRichardson) developed a paper-based analysis device & a 3 minute sampling workflow that requires just a container, a test device and a smartphone app. 2/n
Reaction zones are wax printed onto filter paper. This produces a 2D barrier to contain the reactants (think of them as 2D 'flask' printed onto paper). In the presence of phosphates the zones turn blue via formation of a phosphomolybdenum blue complex. 3/n
