- A central endeavour in bioelectronics is the development of logic elements to transduce and process ionic to electronic signals. Motivated by this challenge, we report fully monolithic, nanoscale logic elements featuring n- and p-type nanowires as electronic channels that are proton-gated by electron-beam patterned Nafion. We demonstrate inverter circuits with state-of-the-art ion-to-electron transduction performance giving DC gain exceeding 5 and frequency response up to 2 kHz. A key innovation facilitating the logic integration is a new electron-beam process for patterning Nafion with linewidths down to 125 nm. This process delivers feature sizes compatible with low voltage, fast switching elements. This expands the scope for Nafion as a versatile patternable high-proton-conductivity element for bioelectronics and other applications requiring nanoengineered protonic membranes and electrodes.

- With consumers increasingly avoiding service brands due to a wide range of transgressions by organisations, it is surprising that research relating to service brand avoidance is lacking, with most studies focusing on positive brand associations. However, more recently researchers started exploring service brand avoidance by gaining insights into this phenomenon through qualitative research by identifying possible reasons as to why consumers would not only avoid service brands, but also terminate their relationships with brands. This paper furthers our understanding of service brand avoidance by being one of the first research studies to quantitatively explore the antecedents of service brand avoidance. Data were collected by means of convenience sampling from 299 South African cell phone users. Findings indicate that of those antecedents of service brand avoidance identified through previous qualitative studies, identity avoidance, moral avoidance, deficit-value avoidance and experiential avoidance predict service brand avoidance, whereas advertising avoidance does not.
