In this study, the reduction-carbonization property of WO3 obtained by thermal decomposition of ammonium paratungstate (APT) under N-2 and air atmosphere in a fluidized bed was investigated. The decomposition property of APT in N-2 and air was analyzed by TG analyzer. Phase, morphology, deoxidation rate and carbonization rate of the decomposed prod...
A co-current flow rotating packed bed was applied to remove volatile organic compounds (VOCs) by sodium hypochlorite (NaClO) and surfactant (sodium dodecyl benzene sulfonate, SDBS) from air stream. Xylene was used as a model VOC herein. The effect of pH, concentration of NaClO and SDBS solution, liquid flow rate, gas flow rate and rotational speed ...
In this research Al2O3/ZnO nanolaminates were evaluated for possible application in the design of optical immunosensors. Total internal reflection ellipsometry (TIRE) was utilized to study the optical response during the formation of a bovine serum albumin (BSA) based monolayer on the surface of Al2O3/ZnO nanolaminates, which were pre-modified with...
With the improvement in sensor technologies, air quality is increasingly being monitored. Two major factors in obtaining relevant information are the optimal placement and the number of air quality sensors. Moreover, in cases of poor air quality, the information of the pollution level given by the deployed sensors is not sufficient. An advanced und...

Two observational campaigns were conducted, one in the Grenoble area (South Eastern France), for the MOCoPo project, near an urban freeway in 2011 and the other one in a Paris suburb, forthe TrafiPollu project, on a major surface street in 2014. PM10 concentrations were measured by Air Rhône-Alpes during the last 10 days of September 2011 for MOCoP...
Experiments have been carried out using the deposition-based Direct Thoron Progeny Sensors (DTPS) in a thoron experimental house. The objective was to study the thoron decay product characteristics such as the deposition velocities, spatial variability and dependence on aerosol particle concentrations. Since the deposition velocity is an important ...
In the present work, detailed experimental investigations have been carried out to understand the role of various spray parameters, such as fuel injection pressure, droplet size distribution, and velocity field on the stabilization of lifted spray flames with kerosene fuel. Six full cone pressure swirl nozzles N1-N6 (fuel flow rate, m(f) = 1.7-7.08...

In this work, a computational fluid dynamics (CFD) modelling has been performed to analyze pulverized coal combustion in a vertical pilot-scale furnace. The furnace with swirl burner is located at the Institute of Heat and Mass Transfer at RWTH Aachen University, where O-2/CO2 combustion environment was adopted to study pulverized coal combustion e...
