Electronic nose (EN) systems play a significant role for gas monitoring and identification in gas plants. Using an EN system which consists of an array of sensors provides a high performance. Nevertheless, this performance ...

Engineering the morphology of rare-earth doped NaYF4-based upconversion nanoparticles (UCNPs) can effectively tune their upconversion luminescence emission (UCLE) properties. Herein, we rationally synthesized a new class ...

The use of microsimulation to model the vehicles movement and pedestrian movements within a traffic network is widely undertaken to test and evaluate operational performance of a traffic network under different traffic ...

In this study, a novel system for contacting gases and liquids, which may be suitable for many applications involving gas-liquid contact or gas-liquid reactions, has been developed and characterized. The system consists ...

This study investigates the characterization and the ability of polyvinyl alcohol (PVA) gel to be used in the area of wastewater treatment as biomass immobilization matrix. The PVA matrix was prepared through the ...

Carbon dioxide (CO2), as one of the major greenhouse gas emissions, has attracted much attention in the world. Magnetite Fe3O4 nanoparticles have a tendency to aggregate in solution to reduce their surface energy due to ...

CO2 is one of the main greenhouse gases that causes global warming, leading to a global detrimental impact on the environment, economy, and society as a whole. Carbon capture is regarded as an important and effective ...

A comparison of properties of electrodeposited Ni-B and Ni-B-ZrO2-Al2O3 nanocomposite coatings is presented to explain the benefits of addition of mixed nanoparticles of ZrO2 and Al2O3 into Ni-B matrix. A comparative study ...

Development of secondary batteries based on abundant and inexpensive elements are vital. Amongvarious alternative choices, sodium-ion batteries (NIBs) are promising because of plentiful resourcesand low costs of sodium ...

Ni-B coatings have high hardness and high wear resistance which make them suitable for automotive, aerospace, petrochemical, textile and electronics industries. Further improvement in properties (especially the corrosion ...
