Physical functionalization of multi-walled carbon nanotubes for enhanced dispersibility in aqueous medium
(
Springer Nature
, 2020 , Article)
Noncovalent functionalization of multi-walled carbon nanotubes (MWCNTs) by anionic surfactants (sodium dodecylbenzene sulfonate; SDBS and sodium cholate; SC) results in stable aqueous dispersions. SDBS showed better ...

High-frequency viscoelastic measurements of fluids based on microcantilever sensing: New modeling and experimental issues
(
Elsevier
, 2013 , Article)
In general, microrheology is carried out using active or passive particle-tracking techniques. In the present paper, a novel technique based on the out-of-plane bending vibrations of a microcantilever beam immersed into a ...
Facile Microwave Synthesis of Hierarchical Porous Copper Oxide and Its Catalytic Activity and Kinetics for Carbon Monoxide Oxidation
(
American Chemical Society
, 2022 , Article)
The synthesis of copper oxide (CuO)-based nanomaterials has received a tremendous deal of interest in recent years. Particularly, the design and development of novel CuO structures with improved physical and chemical ...
Co oxidation at near-ambient temperatures over tio2-supported pd-cu catalysts: Promoting effect of pd-cu nanointerface and tio2 morphology
(
MDPI AG
, 2021 , Article)
Significant improvement of the catalytic activity of palladium-based catalysts toward carbon monoxide (CO) oxidation reaction has been achieved through alloying and using different support materials. This work demonstrates ...
Integrated lab-on-a-chip optical biosensor using ultrathin silicon waveguide soi mmi device
(
MDPI AG
, 2020 , Other)
Waveguides with sub-100 nm thickness offer a promising platform for sensors. We designed and analyzed multimode interference (MMI) devices using these ultrathin platforms for use as biosensors. To verify our design ...
Tailoring the reducibility and catalytic activity of CuO nanoparticles for low temperature CO oxidation
(
Royal Society of Chemistry
, 2018 , Article)
Copper oxide (CuO) nanoparticles have received considerable interest as active and inexpensive catalysts for various gas–solid reactions. The CuO reducibility and surface reactivity are of crucial importance for the high ...
Microstructure and mechanical behavior of hot extruded aluminum/tin-bismuth composites produced by powder metallurgy
(
MDPI AG
, 2020 , Article)
In this study, Al-BiSn composites were synthesized by a combination of microwave sintering and hot extrusion processes. The structural, morphological, mechanical, and thermal properties were investigated to elucidate the ...
