We report results for the electrochemistry of the germanium(II) tri-halide anions, [GeCl3]?, [GeBr3]? and [GeI3]?, in supercritical difluoromethane containing 60?mm [NnBu4][BF4] at 19.1?MPa and 358?K. The voltammetry shows mass-transport-limited curr

We describe the assembly and characterisation of a reference electrode for use in supercritical difluoromethane (R32). The reference electrode is constructed from a europium doped lanthanum fluoride crystal contacted by silver loaded epoxy and encase

For the first time, a versatile electrolyte bath is described that can be used to electrodeposit a wide range of p-block elements from supercritical difluoromethane (scCH2 F2 ). The bath comprises the tetrabutylammonium chlorometallate complex of the

Single crystals of Cu2ZnSnS4 have been produced within sealed quartz ampoules via the chemical vapour transport technique using I2 as the transporting agent. The effects of temperature gradient and I2 load on the crystal habit and composition are con

A novel electro-deposition method based on a rocking disc system with π/3 amplitude and variable frequency is introduced. Uniform copper films were deposited from a 0.1 M CuSO4/3.0 M NaOH/0.2 M sorbitol bath directly onto 12.1 cm2 Mo/MoSe2 substrate

Focused ion beam (FIB) machining allowed a sub-micron trench to be cut through tin-doped indium oxide (ITO) film on glass to give a generator – collector junction electrode with narrow gap (ca. 600 nm). A layer-by-layer deposited film composed of a

Paper surfaces (Whatman filter papers, Kimwipes®, and Japanese Washi papers) were employed as support for gold nanoparticles (AuNPs) deposited by the seed-mediated growth method. The AuNP-modified paper or textile was brought into “weak” (or non

Polyaniline of low molecular weight (ca. 10 kDa) is combined with cellulose nanofibrils (sisal, 4–5 nm average cross-sectional edge length, with surface sulphate ester groups) in an electrostatic layer-by-layer deposition process to form thin nano-

Molecular layer-by-layer assembly from pre-saturated aqueous solutions of Fe3+ and phytate is employed to build up iron phytate deposits on tin-doped indium oxide (ITO) electrodes. Globular films with approximately 1 nm growth per layer are observed
