Experimental methods in chemical engineering: Cyclic voltammetry—CV

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Cyclic voltammetry (CV) is a foundational electroanalytical technique for investigating redox behaviour and evaluating material performance across fields such as molecular electrochemistry, electrocatalysis, sensing, and energy storage. Despite its widespread use, a gap remains between formal electrochemical theory and the practical data ...

Clinical Validation of Four Point‐of‐Care High‐Risk HPV Assays, Including Two Reduced‐Valency Assays, for Cervical Cancer Screening in Low‐Resource Settings

International Journal of Cancer, EarlyView.
High‐risk human papillomavirus (hrHPV) testing improves cervical cancer screening by facilitating earlier detection and prevention. In low‐resource settings, however, cost and increased referrals limit its use. At the same time, many new and more affordable assays lack validation.

An interlaboratory comparison on whole water samples [PDF]

Accreditation and Quality Assurance, 2016
The European Water Framework Directive 2000/60/EC requires monitoring of organic priority pollutants in so-called whole water samples, i.e. in aqueous non-filtered samples that contain natural colloidal and suspended particulate matter. Colloids and suspended particles in the liquid phase constitute a challenge for sample homogeneity and stability ...

Exploiting interlaboratory comparisons [PDF]

Accreditation and Quality Assurance, 2013
Many individuals and laboratory teams, respectively, experience some kind of surprise when they are starting to compare their own measurement results with the ones from other laboratories. It could be a positive astonishment, namely how well the results are matching for a given measurand and sample. More often the contrary is observed and the origin of
