Infrared Imaging As A Non-Invasive Tool For Documenting Maggot Mass Temperatures, Aidan P. Johnson, James F. Wallman
Infrared Imaging As A Non-Invasive Tool For Documenting Maggot Mass Temperatures, Aidan P. Johnson, James F. Wallman
Faculty of Science, Medicine and Health - Papers: part A
Forensic entomology relies on the ability to predict the temperatures to which maggots have been exposed, due to the resultant impact on their growth rate. Mercury thermometers and electrical temperature sensors have traditionally been used to record temperatures of maggot masses, cadavers and the surrounding soil and air. However, these techniques are limited to one measurement at a time and thus may not accurately describe the complexities of the thermal environment of the cadaver. Infrared imaging has gained increasing popularity because of its resolution, affordability and portability. Using decomposing pig carcasses, the current study showed that surface temperature measurements recorded …
Ambient Ionisation Mass Spectrometry For The Characterisation Of Polymers And Polymer Additives: A Review, Martin R. L Paine, Philip J. Barker, Stephen J. Blanksby
Ambient Ionisation Mass Spectrometry For The Characterisation Of Polymers And Polymer Additives: A Review, Martin R. L Paine, Philip J. Barker, Stephen J. Blanksby

The purpose of this review is to showcase the present capabilities of ambient sampling and ionisation technologies for the analysis of polymers and polymer additives by mass spectrometry (MS) while simultaneously highlighting their advantages and limitations in a critical fashion. To qualify as an ambient ionisation technique, the method must be able to probe the surface of solid or liquid samples while operating in an open environment, allowing a variety of sample sizes, shapes, and substrate materials to be analysed. The main sections of this review will be guided by the underlying principle governing the desorption/extraction step of the analysis; …
Desorption Electrospray Ionisation Mass Spectrometry Of Stabilised Polyesters Reveals Activation Of Hindered Amine Light Stabilisers, Martin R.L Paine, Ganna Gryn'ova, Michelle L. Coote, Philip J. Barker, Stephen J. Blanksby

The use of hindered amine light stabilizers (HALS) to retard thermo- and photo-degradation of polymers has become increasingly common. Proposed mechanisms of polymer stabilisation involve significant changes to the HALS chemical structure; however, reports of the characterisation of these modified chemical species are limited. To better understand the fate of HALS and determine their in situ modifications, desorption electrospray ionisation mass spectrometry (DESI-MS) was employed to characterise ten commercially available HALS present in polyester-based coil coatings. TINUVIN® 770, 292, 144, 123, 152, and NOR371; HOSTAVIN® 3052, 3055, 3050, and 3058 were separately formulated with a pigmented, thermosetting polyester resin, cured …
