3D printing technology provides a unique platform for rapid prototyping of numerous applications due to its ability produce low cost printed platforms. Herein, graphene-based polylactic acid filament (graphene/PLA) has been fabricate range disc electrode (3DE) configurations using conventional RepRap fused deposition moulding (FDM) printer, which requires no further modification/ex-situ curing step. To provide proof-of-concept, these architectures are characterised both electrochemically and...
Screen-printed electrochemical sensing platforms, due to their scales of economy and high reproducibility, can provide a useful approach translate laboratory-based electrochemistry into the field. An important factor when utilising screen-printed electrodes (SPEs) is determination real surface area, which allows for benchmarking these SPEs an parameter in quality control. In this paper, we consider use cyclic voltammetry chronocoulometry allow area highlighting experimentalists various...
Fluorine doped tin oxide (FTO) coatings have been prepared using the mid-frequency pulsed DC closed field unbalanced magnetron sputtering technique in an Ar/O2 atmosphere blends of and fluoride powder formed into targets. FTO were deposited with a thickness 400 nm on glass substrates. No post-deposition annealing treatments carried out. The effects chemical composition structural (phase, grain size), optical (transmission, band-gap) electrical (resistivity, charge carrier, mobility)...
An electron-emitting probe has been used to measure the temporal evolution of plasma potential Vp along a line from target (Ti) substrate above racetrack in high-power impulse magnetron sputtering discharge pulsed at 100 Hz. The 20 ns time-resolution allowed us observe highly dynamic nature as voltage waveform develops, with large negative values (−210 V) and strong gradients existing magnetic trap region first 6 8 µs. After 55 60 µs, is elevated towards ground (0 bulk electric field...
2D molybdenum disulphide nanosheets are explored as an electrocatalyst towards the hydrogen evolution reaction (HER) using modified carbon based electrodes.
Using an energy-resolved mass spectrometer and a time-resolved Langmuir probe, the distribution of bombarding ion energies, their fluxes energy at substrate in asymmetric bi-polar pulsed DC magnetron have been determined. The discharge was operated Ar pressure 0.53 Pa with Ti target frequencies 100 350 kHz range duty cycles (from 50 to 96%). At kHz, Ar+and Ti+ time-averaged functions (IEDFs) reveal three peaks, which are low (<10 eV), mid-range (20-50 eV) high (60-100 eV). We correlate these...
It is well established that the microstructure of a thin film strongly influences its physical and chemical properties. Microstructure, in turn, determined by number deposition process parameters which control energy delivered to growing film. The closed-field unbalanced magnetron sputtering (CFUBMS) has now been developed stage where it can be routinely used deposit very high quality, adhered coatings wide range metals ceramics. A key factor success this ability transport large ion currents...
Abstract Herein, we report the fabrication and application of Li‐ion anodes for utilisation within batteries, which are fabricated via additive manufacturing/3D printing (fused deposition modelling) using a bespoke graphene/polylactic acid (PLA) filament, where graphene content can be readily tailored controlled over range 1–40 wt. %. We demonstrate that 20 % exhibits sufficient conductivity critically, effective 3D printability rapid manufacturing printed freestanding (3DAs); simplifying...
An internal standard protocol is utilised to simultaneously characterise and utilise carbon-based electrode materials during their implementation.
The marked difference in behaviour between HiPIMS and conventional DC or pulsed-DC magnetron sputtering discharges with changing magnetic field strengths is demonstrated through measurements of deposition rate.To provide a comparison techniques the same circular was operated three excitation modes at fixed average power 680 W pressure 0.54 Pa nonreactive titanium.The total strength B cathode surface middle racetrack varied from 195 to 380 G. show expected that rates fall decreasing (here by...
