This paper outlines the centralized design and production of ultra-high-vacuum sidearm laser-stabilization systems for AION Ultra-Cold Strontium Laboratories. Commissioning data on residual gas steady-state pressures in chambers, magnetic field quality, laser stabilization, loading rate 3D magneto-optical trap are presented. Streamlining stabilization enabled Collaboration to build equip parallel five state-of-the-art Laboratories within 24 months by leveraging key expertise collaboration....
Most recommended methods for visualising fingermarks on paper rely chemical developers that target and react with amino acids. Traditionally, these are sprayed onto substrates in solutions of per- polyfluoroalkyl substances (PFAS), but now those same PFAS chemicals undergoing phaseout or phasedown, which threatens to undermine forensic capabilities. This situation provides an opportunity pivot towards greener approaches fingermark visualisation. The ideal methodology would be a water-based...
Water-based fingermark development treatments for paper have long been held back by loss of ridge detail due to diffusion. Viscous hydrogels (≥2224 cP) show promise as a green method delivering chemical developers that inhibits diffusion, thereby preserving detail. This is demonstrated here with starch and xanthan gum applied iodine-fumed fingermarks.
A 4- tpt fingerprint powder exhibiting long-lived phosphorescence has been developed to suppress background fluorescence. This is demonstrated using standard forensic equipment on challenging surfaces while eschewing specialized imaging techniques.
A facile route to spiro-γ-lactams containing fused seven- and five-membered rings is showcased here in a multicomponent reaction harnessing glycine. Four were characterised, including by X-ray diffraction techniques, showing...

A global phase-out of the hydrochlorofluorocarbon solvent AK-225 (HCFC-225), a carrier used in certain all-in-one iodine solutions, has mandated reassessment HFE-7100 as an alternate solvent. Direct substitution for failed owing to incompatible solubility, prompting evaluation blends containing both heptane and dichloromethane. This heterogenous formulations yielded new solution, modified α-naphthoflavone fixing developer solution with stability ~4 hours. The blended spray reagent delivers...
