Various tandem cell configurations have been reported for highly efficient and spontaneous hydrogen production from photoelectrochemical solar water splitting. However, there is a contradiction between two main requirements of a front photoelectrode in a tandem cell configuration, namely, high transparency and high photocurrent density. Here we demonstrate a simple yet highly effective method t...

Chemical ionization mass spectrometry (MS) and tandem mass spectrometry (MS/MS) experiments have been performed for the structural characterization and isomeric differentiation of two series of C- and O-linked arylglycosides with potential antioxidant activity. Different amines have been used for producing gas phase chemical ionization. Depending on their proton affinity and steric hindrance, a...

PAGE gel, individual proteins were either visualized by Coomassie Brilliant Blue stain excised and subjected to an in-gel tryptic digest (digests were performed as described (Shevchenko et al, 1996), or the eluted CenH3 particles were precipitated with 10% trichloroacetic acid, washed once with acetone, dried, re-dissolved in de-ionized water, and digested in solution with Arg-C protease. For C...

Abstract In the world of oil and gas, there will definitely be a structure for either production process, exploration so on. The consists three types, namely fixed structure, floating moored structure. Floating structures can best option in terms cost time. Things that interfere with when operating are environmental loads. One example its operation is offloading, it offloading side by or tandem...

Early in its mission, the Landsat-7 spacecraft was temporarily placed in a ‘‘tandem’’ orbit very close to that of the Landsat-5 spacecraft in order to facilitate the establishment of sensor calibration continuity between the Landsat-7 Enhanced Thematic Mapper Plus (ETM+) and Landsat-5 Thematic Mapper (TM) sensors. The key period for the tandem configuration was June 1–4, 1999, during which hund...

Abstract The paper presents an experimental investigation of air flow around bluff bodies in tandem configurations. first one concerns two square cylinders and the second a triangular cylinder was used as upstream object. Experiment performed for different Reynolds number fixed distance between bodies. To have insight into fluid flow, particle image velocimetry method used. Particular attention...

Interferometric satellite synthetic aperture radar (SAR) data was acquired from an area on Spitsbergen, Svalbard, during the European remote sensing satellite (ERS) Tandem mission in 1995–1996. Analyzing these data sets shows that the estimated SAR coherence is highly dependent on the satellite baseline length, and that corrections for this decorrelation effect is necessary if the baseline is a...

Kesterite Cu2ZnSn(SxSe1−x)4 has tunable band-gap values in the range 1 to 1.5 eV depending upon Sulphur/Selenium stoichiometry. We analyze proposed tandem configuration of kesterite absorber family using SCAPS-1D for device performance. Pure sulphide Cu2ZnSnS4 (CZTS) bandgap is utilized as top cell and a sulpho-selenide (CZTSSe) 1.1 bottom stacked configuration. utilize script file capability S...

A silicon detector with a fast electronics chain is used for the dosimetry of protons in range 0.5–5 MeV at Centro Nacional de Aceleradores (CNA) 3 MV Tandem laboratory Seville, Spain. In this configuration, measurements can be performed pulsed mode, using digitizer to record event-by-event proton energy depositions. The distributions deposited were obtained thanks calibration an alpha source. ...
