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
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…
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
