Electrode poisoning and interferences from complex biological environments are major challenges in the development of in-situ H2S sensors. To circumvent these issues, herein a robust electrode based on reduced graphene oxide-molybdenum disulfide nanohybrid (RGO-MoS2) polymerized o-phenylenediamine (POPD) is developed. The POPD/RGO-MoS2-modified catalyzed oxidation at minimized overpotential (+ ...

Nano-sized nickel oxide (nano-NiO) is a new nanomaterial that has shown great promise in many areas of application. Understanding its environmental fate and effects is critical for minimizing the potential environmental implications of this new material due to incidental and accidental releases in the future. In this study, we observed strong adsorption of tetracycline to nano-NiO and found tha...

The surface of magnetite nanoparticles as nano-sized solid support was modified with a molybdenum-Schiff base complex to prepare an easily separable heterogeneous catalyst for the epoxidation of olefins. Characterization techniques such as Fourier transform infrared and inductively coupled plasma optical emission spectroscopies, X-ray diffraction, vibrating sample magnetometry, scanning, an...

The activation of small alkane molecules originating from natural gas or renewable resources on metal oxide surfaces regains increasing scientific interest since direct utilization of saturated hydrocarbons will offer alternative pathways to higher value chemicals in a postpetroleum era. The focus of the project lies on oxidation catalysis of small alkane molecules including methane, ethane, pr...

In order to study the effects of bio fertilizers and zinc application on yield, variations of quantum yield, stomatal conductance and some physiological traits of triticale under water withholding conditions, a factorial experiment was conducted based on randomized complete block design with three replications. Experimental factors were included water withholding in three levels (normal irrigat...

Nano-sized particles of manganese oxides have been prepared by a very simple and cheap process using a decomposing aqueous solution of manganese nitrate at 100 °C. Scanning electron microscopy, transmission electron microscopy and X-ray diffraction spectrometry have been used to characterize the phase and the morphology of the manganese oxide. The nano-sized manganese oxide shows efficient cata...
