The impact of nanosizing on the phase transition mechanisms of electrode materials is still not well understood. In this study, we reveal that nanosizing can lower the energy barrier and entropy changes associated with phase transformations, ultimately improving the electrochemical performance of nanoporous antimony electrodes in comparison to microsized antimony.

Arrays of thermoelectric nanowires embedded in organic films are attracting increasing interest to fabricate flexible thermoelectric devices with adjustable dimensions and complex shapes, useful for sustainable power sources of portable electronic devices and wireless sensor networks. Here, we report the electrochemical synthesis of interconnected bismuth-antimony (Bi Sb ) nanowires (with 0.06 < < 0.

We report reversible switching of oxazine, cyanine, and rhodamine dyes by a nanoporous antimony-doped tin oxide electrode that enables single-molecule (SM) imaging of electrochemical activity. Since the emissive state of each fluorophore is modulated by electrochemical potential, the number of emitting single molecules follows a sigmoid function during a potential scan, and we thus optically determine the formal redox potential of each dye. We find that the presence of redox mediators (phenazine methosulfate and riboflavin) functions as an electrochemical switch on each dye's emissive state and observe significantly altered electrochemical potential and kinetics.

The emergence of drug-resistant strains of the parasite infecting dogs and humans represents an increasing threat. genomes are complex and unstable with extensive structural variations, ranging from aneuploidies to multiple copy number variations (CNVs). These CNVs have recently been validated as biomarkers of concerning virulence, tissue tropism, and drug resistance.
