Few-layer graphene (FLG) has been predicted to exist in various crystallographic stacking sequences, which can strongly influence the material's electronic properties. We demonstrate an accurate and efficient method to characterize stacking order in FLG using the distinctive features of the Raman 2D-mode. Raman imaging allows us to visualize directly the spatial distribution of Bernal (ABA) and...

Advances in the applications of thin-layer chromatography (TLC) and high-performance thin-layer chromatography (HPTLC) for the separation, detection, and qualitative and quantitative determination of pesticides, other agrochemicals, and related compounds are reviewed for the period 1998-2000. Analyses are covered for a variety of samples, such as food, biological, and environmental, and for res...

Quantized double layer (QDL) charging of a Au130(SR)50 nanomolecule is reported for the first time. In the past, QDL charging was known only for Au144(SR)60 and Au225(SR)75 nanomolecules, which intrigued much research in this field. Here, using differential pulse voltammetry, we demonstrate that Au130 shows QDL charging. Furthermore, 13 different oxidation-reduction waves corresponding to singl...

Sacrificial layer electrophoretic deposition (SLED) is a technique to assemble nanoparticles that yields free-standing, multilayered nanoparticle films with macroscopic lateral dimensions after the sacrificial layer is dissolved.

Large-scale growth of low-cost, efficient, and durable non-noble metal-based electrocatalysts for water splitting is crucial for future renewable energy systems. Atomic layer deposition (ALD) provides a promising route for depositing uniform thin coatings of electrocatalysts, which are useful in many technologies, including the splitting of water. In this communication, we report the growth of ...

Recently, magnetic split-flow thin (SPLITT) fractionation has been developed to separate macromolecules, colloids, cells and particles. However, the previous theory, developed for an infinitely long channel, needs to be improved to consider the flow transit regimes at both inlet and outlet. In this paper, we describe a new approach to optimising flow-rates for particle separation which consider...
