  • Making environmental sensors on plastic foil - Review article Making environmental sensors on plastic foil - Review article
    With the emergence of the printed electronics industry, the development of sensing technologies on non conventional substrates such as plastic foils is on-going.
  • Graphene in biosensing - Review article Graphene in biosensing - Review article
    Biosensing is paramount for improving the quality of human life. Biosensors and biosensing protocols are able to detect a wide range of compounds, sensitively and selectively, with applications in security, health care for point-of-care analyses of diseases, and environmental safety.
  • The role of palladium in a hydrogen economy
    We are facing accelerated global warming due to the accumulation of greenhouse gases. A hydrogen-based economy is one potential approach toward maintaining our standard of living while lowering carbon dioxide emissions. Palladium is a unique material with a strong affinity to hydrogen owing to both its catalytic and hydrogen absorbing properties.
  • Precious metal magic: catalytic wizardry Precious metal magic: catalytic wizardry
    Magic: “Influencing the course of events by using mysterious or supernatural forces.” Precious metals are alluring and magical because of their inactivity toward chemical reactions; they are extremely stable and hence are also termed “noble metals.” During the industrial revolution mankind realized that noble metals have the power to influence the course of chemical events – through catalysis. A catalyst is defined as a substance that facilitates a chemical transformation without itself being consumed in the process; this power has a mysterious, almost magic-wand character.

  • 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.
