Electrochemical Strain Microscopy of Li-ion Conductive Materials for Energy Generation & Storage
Electrochemical strain microscopy (ESM) is a novel scanning probe microscopy (SPM) technique available exclusively for the Cypher™ and MFP-3D™ atomic force microscopes (AFMs) from Asylum Research that is capable of probing electrochemical reactivity and ionic flows in solids with unprecedented resolution. Only with understanding of electrochemical functionality on the level of individual nanoparticles or structural defects can practical, knowledge-driven energy storage research and development proceed. ESM’s capabilities are invaluable for investigating and improving performance for a broad range of energy technologies, including batteries and fuel cells for electric vehicles and grid storage, the viability of which hinges on advances in energy storage densities and lifetimes. ESM has the potential to aid in these advances with two major improvements over other current technologies: (a) the resolution to probe nanometer-scale volumes and (b) imaging capability extended to a broad range of spectroscopic techniques. This note explains how ESM works and describes applications of this new technique for Li-ion electrolytes and cathode and anode materials, including imaging and spectroscopic methods – this note is recommended reading for all those working on improving battery and fuel cell performance.
Graphene in biosensing
We describe how biosensors and biosensing systems can employ graphene.
Rapid synthesis of Pb5(VO4)3I, for the immobilisation of iodine radioisotopes, by microwave dielectric heating
Rapid synthesis of Pb5(VO4)3I, a potential immobilisation host for iodine radioisotopes, was achieved in an open container by microwave dielectric heating of a mixture of PbO, PbI2, and V2O5 at a power of 800 W for 180 s (at 2.45 GHz). The resulting ceramic bodies exhibited a zoned microstructure, differentiated by inter-granular porosity and phase assemblage, as a consequence of the inverse temperature gradient characteristic of microwave dielectric heating.
Evaluating the characteristics of multiwall carbon nanotubes
During the past 20 years, multiwall carbon nanotubes (MWCNTs) have become an important industrial material. Hundreds of tons are produced each year. This review is a survey of the scientific literature, motivated by industrial requirements and guidelines for environment, health and safety compliance.
Materials-based hydrogen storage: Attributes for near-term, early market PEM fuel cells
Although hydrogen is widely recognized as a promising energy carrier for the transportation sector, widespread adoption of hydrogen and fuel cell technologies depends critically on the ability to store hydrogen at adequate densities, as well as release hydrogen at sufficient rates (among other requirements) to meet PEM fuel cell power plant requirements.
