Voltammetric pH sensor based on electrochemically modified pseudo-graphite.

A nanocrystalline graphite-like amorphous carbon (graphite from the University of Idaho thermolyzed asphalt reaction, GUITAR) shares morphological features with classical graphites, including basal and edge planes (BP, EP). However, unlike graphites and other sp2-hybridized carbons, GUITAR has fast heterogenous electron transfer (HET) across its basal planes, and resistance to corrosion similar to sp3-C and boron-doped diamond electrodes. In this contribution, quinoid modified BP-GUITAR (q-GUITAR) is examined as a sensor for pH determination.

Swimming Against the Current: A Qualitative Review of the Work Experiences and Adaptations Made by Employees With Arthritis.

Objective: To describe the experiences and strategies of employees with arthritis to maintain employment, and to use this information to build a conceptual model.

Methods: We conducted a systematic review of qualitative studies that examined the work experiences of employees with arthritis. Published studies on arthritis and employment were searched from electronic databases (1980-2017) and bibliographic reviews of relevant studies.
