Tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. Photo degradation of Congo Red (azo dye) showed that photo catalytic property of the as-prepared WO3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. Photo degradation of Rhodamine B (...

Abstract Photo-voltaic inverts usually use LCL filter for filtering, and will bring resonance problems to the system. This paper focuses on invert-er side current feedback control (invert-er feedback, ICF). proposes a method suppressing of photo-voltaic clusters based capacitor voltage feed-forward. First, establish ICF mathematical model HPF CVF under weak grid, qualitatively analyze mechanism...

The purpose of the research described herein was to develop simple, precise and accurate isocratic stability indicating reversed phase HPLC assay method for determination of Tapentadol solid dosage forms. Isocratic RP-HPLC method was developed on Phenomenex Luna C8 150 4.6mm, 5μm column using mobile phase as methanol – 0.002 M potassium dihydrogen phosphate buffer pH 3.0 (60: 40 v/v) at a flow...

A nanostructured plasmonic photocatalyst, silver/silver thiocyanate (Ag@AgSCN), has been prepared by a simple precipitation method followed by UV-light-induced reduction. The ratio of Ag to silver thiocyanate (AgSCN) can be controlled by simply adjusting the photo-induced reduction time. The formation mechanism of the product was investigated based on the time-dependent experiments. Further exp...

Two routes to the thermal decomposition of poly(propylene carbonate) (PPC) have been consideredpolymer chain-end unzipping and random chain scission. The inhibition and catalysis of each mechanism has been studied. End-capping of low molecular weight (2 kDa) PPC has been achieved and confirmed with NMR analysis resulting in stabilization from unzipping. Citric acid was used as an additive and s...

Pure nano-Al13 and aggregates at various concentrations were prepared to examine the particle size effect of coagulation with inorganic polymer flocculant. The property and stability of various species formed were characterized using Infrared, 27Al-NMR, photo correlation spectroscopy (PCS), and Ferron assay. Results showed that concentration and temperature exhibited different roles on the stab...
