Pencil beam all-optical ultrasound imaging
A miniature, directional fibre-optic acoustic source is presented that employs geometrical focussing to generate a nearly-collimated acoustic pencil beam. When paired with a fibre-optic acoustic detector, an all-optical ultrasound probe with an outer diameter of 2.5 mm is obtained that acquires a pulse-echo image line at each probe position without the need for image reconstruction. B-mode imag...
متن کاملPlastic waste is all at sea
Washed up: Litter found on a beach near Tromsø, Norway. (Photo: © Bo Eide.) In the 18th century, when James Cook explored the Pacific on the Endeavour, there were large islands still unknown to European civilisation for him to discover. When Darwin visited the Galápagos Islands with HMS Beagle in 1835, a wealth of biological diversity awaited scientific analysis. The most recent expedition sett...
متن کاملCortical Cliques: A Few Plastic Neurons Get All the Action
Adjustments in neural activity can drive cortical plasticity, but the underlying circuit components remain unclear. In this issue of Neuron, Barnes et al. (2015) show that visual deprivation-induced homeostatic plasticity invokes specific changes among select categories of V1 neurons.
متن کاملAll graphene-based thin film transistors on flexible plastic substrates.
High-performance, flexible all graphene-based thin film transistor (TFT) was fabricated on plastic substrates using a graphene active layer, graphene oxide (GO) dielectrics, and graphene electrodes. The GO dielectrics exhibit a dielectric constant (3.1 at 77 K), low leakage current (17 mA/cm(2)), breakdown bias (1.5 × 10(6) V/cm), and good mechanical flexibility. Graphene-based TFTs showed a ho...
متن کاملPencil it in: pencil drawn electrochemical sensing platforms.
Inspired by recent reports concerning the utilisation of hand drawn pencil macroelectrodes (PDEs), we report the fabrication, characterisation (physicochemical and electrochemical) and implementation (electrochemical sensing) of various PDEs drawn upon a flexible polyester substrate. Electrochemical characterisation reveals that there are no quantifiable electrochemical responses upon utilising...
