The cation deficient complex oxides of (Ca/Sr)MoO4 - BiVO4 Bi2Mo3O12 triple system are promising photocatalysts and pigments. Compounds with general formula Ca1−1.5x-yBix+yФxMo1-yVyO4 Sr1−1.5x-yBix+yФxMo1-yVyO4 were synthesized byconvention solid state technique in the range 550–720 °C. Two wide regions solutions (ordinary superstructured scheelite-type phases respectively) found for each syste...

A new, rapid methodology for trace analysis using solid-phase extraction is described. The two-step methodology is based on the concentration of an analyte onto a membrane disk and on the determination by diffuse reflectance spectroscopy of the amount of analyte extracted on the disk surface. This method, which is adaptable to a wide range of analytes, has been used for monitoring ppm levels of...

The determination of the band gap energy (Eg) semiconductors powder materials can be performed from diffuse reflectance spectroscopy (DRS) measurements. For this purpose, classical theory proposed by Kubelka and Munk (K-M) so-called plot Tauc, both discussed here, have been largely employed. We investigate Eg values anatase TiO2 particles synthesized precipitation titanyl sulphate in presence 5...

The worldwide increase in generation of solar based electricity prompts the essentiality research efforts on development energy storage systems. In this regard, self-powered photocapacitors are keen interest as they can directly convert and store form electrical a single device. This study reports photoelectrochemical capacity novel photocapacitor fabricated with FTO/Activated Carbon (AC)/Ag2Cr...

We present a prediction model for digital printers and more specifically for electrophotographic devices. On the one hand, we propose an electrophotographic simulation model which estimates the microscopic structure of any printed toner layer based on its input halftone bitmap. Applying BOUGUER–BEER–LAMBERT’s law, the obtained spatial toner arrangement yields the spectral transmittance distribu...
