“…1500 mW m À2 with SS or copper) remained higher than the best result of 1310 mW m À2 at cycle 11 (20 days of operation, 100 mM phosphate buffer) using neutral hydrophilic binders [15]. Completely replacing the Nafion binder with PTFE has been shown to result in a very low power production of 549 mW m À2 [13], which was less than one third of power production that obtained here using the PDMS binder (although a brush anode was used in this study, as opposed to a carbon cloth anode). The use of PDMS binder does not require heating, compared to the PTFE binder that needs to be heated to 370 C after application for fusing of the PTFE emulsion particles.…”

“…Mixtures of PTFE and Nafion have been examined, and power decreased as the amount of PTFE was increased in the binder mixture. With only the PTFE binder, the maximum power was 549 mW m À2 , compared to 1060 mW m À2 obtained using only Nafion [13]. Comparison of sulfonated and non-sulfonated poly (-sulfone) showed that the non-ionic binder had better electrochemical performance and the lowest charge transfer resistance, suggesting that the ionic binder resulted in ionic gradients that impeded proton transfer [14].…”

“…Efforts have been made to find alternatives to Nafion, because it is a very expensive polymer which costs $667 per m 2 . Low-cost hydrophobic polytetrafluoroethylene (PTFE) has been tested as the binder in several studies [12,13]. Replacing Nafion with PTFE in a MFC decreased power generation from 480 AE 20 mW m À2 to 360 AE 10 mW m À2 , although the PTFE binder showed less degradation in performance over time [12].…”

“…[165] However, where cracks initiate within brittle components, it is likely that continued strain cycling will lead to crack propagation, delamination, and eventual failure. [79] While this is not a concern for wearable devices, it is unsuitable for implantable electronics.…”

Traditionally, conductive materials for electrodes are based on high modulus metals or alloys. Development of bioelectrodes that mimic the mechanical properties of the soft, low modulus tissues in which they are implanted is a rapidly expanding field of research. Many polymers exist that more closely match tissue mechanics than metals; however, the majority do not conduct charge. Integrating conductive properties via incorporation of metals and other conductors into nonconductive polymers is a successful approach to producing polymers that can be used in electrical interfacing devices. When combining conductive materials with nonconductive polymer matrices, there is often a tradeoff between the electrical and mechanical properties. This review analyzes the advantages and disadvantages of approaches involving coating or layer formation, composite formation via dispersion of conductive inclusions through polymer matrices, and in situ growth of a conductive network within polymers.

S U M M A R YIchthyophthirius multifiliis is a widespread, ciliated protozoan ectoparasite of fish. In the present study, we investigated the effects of metal nanoparticles on the reproduction and infectivity of free-living stages of I. multifiliis. We determined that ∼50% of theronts could be killed within 30 min of exposure to either 20 ng mL −1 gold, 10 ng mL −1 silver or 5 ng mL −1 zinc oxide nanoparticles. Silver and zinc oxide nanoparticles at concentration of 10 and 5 ng mL −1 killed 100 and 97% of theronts, respectively and inhibited reproduction of tomonts after 2 h exposure. Gold nanoparticles at 20 ng mL killed 80 and 78% of tomonts and theronts 2 h post exposure, respectively. In vivo exposure studies using rainbow trout (Oncoryhnchus mykiss) demonstrated that theronts, which survived zinc oxide nanoparticles exposure, showed reduced infectivity compared with control theronts. No mortalities were recorded in the fish groups cohabited with theronts exposed to either nanoparticles compared with 100% mortality in the control group. On the basis of the results obtained from this study, metal nanoparticles particularly silver nanoparticles hold the best promise for the development of effective antiprotozoal agents useful in the management of ichthyophthiriosis in aquaculture.
