We have developed a technique for the printing of fine copper lines using solutions of a metal organic precursor, copper hexanoate (CuHex). Liquid ribbons 500 μm wide, deposited on a glass substrate either by ink-jetting or capillary writing, are observed to split into two or four finer lines depending on the solution concentration. Surface profiles indicate that the thickness, width and number...

The resonance Raman spectra of (IAuI)~-anions in the organic superconductor Y?-(BEDTTTF)2IAUI as well as in the electrolyte salt n-Bu4AuI2 are investigated. In contrast to /?-(BEDT-TTF)2I3 in the crystals of /?-(BEDT-TTF)2IAuI at low temperature only one Raman line at 120 cm" 1 corresponding to the symmetrical stretching mode of the (IAuI)"-anion is observed. No distinct change in the Raman spe...

Since the advent of Fourier transform methods in high resolution NMR, the organic chemists and, to a lesser extent, the biochemists, have exploited the immense promise of carbon-13 spectroscopy. But to do this effectively they needed a reliable method of broadband proton decoupling, for this makes the carbon-13 spectra very much simpler to interpret and it increases the sensitivity by gathering...

The recent ban on cow slaughtering in India has brought into debate highly emotive and contentious issues to the forefront The meat industry is characterized by controls across the entire value-chain of production and sale, which not only hampers its efficiency but also exacerbates the. The growth and development in meat industry in particular and the country in general has multiple linkages wi...

Although membrane vesicle studies have established the driving forces that mediate renal organic anion secretion and the organic anion transporter Oat1 has now been cloned in several species, its stoichiometry has remained uncertain. In this study, we used electrophysiology, kinetic measurements, and static head experiments to determine the coupling ratio for Oat1-mediated organic anion/dicarbo...

A prototype analyser incorporating commercial analytical instrumentation has been used to monitor the sucrose contamination of boiler feed water. The instrument has been designed to use a commercially available pulsed amperometric detector and incorporates a short chromatographic column. This allows the choice of flow-injection or chromatographic mode of operation. The former is simpler, but no...

In this paper, the results of imaging experinents with the interfacial region~ of representative solid material joints, ~1ng a transmission-type scanning acoustic microscope operating at 150 HHz, are reported. Voids and flaws in specially made joints as well as production-line silicon solder bonds (die bonded headera' have been detected using the transmission~de of operation of the microscope. ...

Spin transport properties in the organic conductor (perylenyls)+ Xwere studied in the temperature ran e of 4-300 K. Being constant in the Q -1 “metallic” range (01, = 1.8(2) cm s , the diffusion constant Dl, exhibits a temperature activated behaviour in the low temperature range, at variance with the prediction invoking the model of an intrinsic semiconductor. A low-temperature divergence of th...

The electroanalytical techniques of pulse polarography, stripping voltammetry and on-line electrochemical detection have been used for the identification and determination of trace concentrations of a wide variety of environmentally significant organic molecules, usually after the application of sample pretreatment procedures, certain separation techniques and, in some cases, derivatisation. Cl...
