Multi-Walled Carbon Nanotubes Composites for Microwave Absorbing Applications
Applied Sciences, 2019 The response of materials to impinging electromagnetic waves is mainly determined by their dielectric (complex permittivity) and magnetic (complex permeability). In particular, radar absorbing materials are characterized by high complex permittivity (and

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore
Advanced Functional Materials, EarlyView.To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Logarithmic derivative complex permittivity spectrometry
Measurement Science and Technology, 2003 A frequency domain method for the advanced dielectric spectrometry of liquids is proposed. It utilizes the feasibility of simultaneously measuring the input admittance or reflection coefficient of the specimen cells and the derivative of these cell parameters with respect to frequency using modern input impedance or network analysers.
