One of Material Science's main challenges is constantly searching for new versatile materials. In this sense, nanocomposites have emerged as an alternative to new substrates due to their unique properties. These hybrid systems are made up of organic polymers with inorganic components. This ideal "tandem" is made up of organic polymers (for example,...

Conductive polymers (CP), such as poly(3,4-ethylenedioxythiophene) (PEDOT), exhibit exceptional physical, chemical, and electrical properties [1] that position them as effective alternatives for the manufacture of electrode materials for energy storage applications [2]. In order to increase the stability of the polymer, and thus extend the lifespan...

The urgent need for a decarbonized power sector has been one of the most important motivations to get a full transition from the fossil-fuel energy sources to a sustainable energy future based on renewable energy alternatives. In this regard, energy conversion and storage devices, such as batteries, fuel cells and supercapacitors, play a key role i...

Cobalt oxide (Co3O4)-based nanostructures have the potential as low-cost materials for lithium-ion (Li-ion) and sodium-ion (Na-ion) battery anodes with a theoretical capacity of 890 mAh/g. Here, we demonstrate a novel method for the production of Co3O4 nanoplatelets. This involves the growth of flower-like cobalt oxyhydroxide (CoOOH) nanostructures...

Conducting polymers (CPs) find applications in energy conversion and storage, sensors, and biomedical technologies once processed into thin films. Hydrophobic CPs, like poly(3,4-ethylenedioxythiophene) (PEDOT), typically require surfactant additives, such as poly(styrenesulfonate) (PSS), to aid their aqueous processability as thin films. However, e...

A solution-based synthesis of well-ordered Cu-rich silicide nanoarchitectures, consisting of a pair of layered cups and stems (ρ-Cu15Si4), is demonstrated. The as-grown ρ-Cu15Si4 typically exhibits distinct interconnected 1D stems consisting of a stack of nanorods (∼300 nm in length) terminated with concave hexagonal 3D cups that evolve through a s...

The investigation of electrochemical processes at the interface of two immiscible electrolyte solutions (ITIES) is of great interest for sensing applications, and serves as surrogates to study biological transport phenomena, e.g. ion channels. Besides e-beam lithography, focused ion beam (FIB) milling is an attractive method to prototype and fabric...

The direct experimental characterization of diffusion processes at nanoscale remains a challenge that could help elucidate processes in biology, medicine and technology. In this report, two experimental approaches were employed to visualize ion diffusion profiles at the orifices of nanopores (radius (ra) of 86±6 nm) in array format: 1) electrochemi...

Electrochemical methods of chemical analysis have been widely used for many years, most especially the trusty pH electrode and conductivity meter, but also in the mass-manufactured glucose test strips which place electrochemical measurements into the hands of non-scientists. The purpose of this volume is to address advances that will enable new mea...

We report here a way for improving the stability of ultramicroelectrodes (UME) based on hexacyanoferrate-modified metals for the detection of hydrogen peroxide. The most stable sensors were obtained by electrochemical deposition of six layers of hexacyanoferrates (HCF), more specifically, an alternating pattern of three layers of Prussian Blue and...
