Background: Enhancement of heat transfer rate is one of the most important aims in industrial applications. The conventional fluids including oil, water and ethylene glycol have poor thermal properties compared to those of most solids. With this information, it leads to the idea that, if we disperse very small particles and let them suspend stably in base fluids, thermal conductivities of that base fluids should be higher. In pr Read More

Background: Although pristine and modified manganese oxides were used as adsorbent for dyes removal from aqueous solutions, their applications were limited to the removal of single dye components. From the practical viewpoint, it is necessary to investigate the adsorption behavior of dyes on manganese oxide adsorbents in multi-component systems. Herein, the present work investigated the performance of core-shell mag Read More

Background: Quantum-dot (QD) superlattice solar cells can attain quite high energy conversion efficiencies. The formation of epitaxial QD superlattice is very difficult since extremely delicate control is required for the QD stacking during the growth to avoid QD deformation and dislocation generation. It is well known that CQDs are self-assembled to form superlattice in electron microscope area after sedimentati Read More

Background: Arsenic considered as one of the most frequent and most toxic heavy metals. The WHO guideline value for arsenic in drinking water was lowered to 10 ppm. But nevertheless, surface water with arsenic concentrations 200 ppm has also been reported. The presence of arsenic in water resources causes various diseases including cancer, blood pressure, symptoms of skin and etc… several methods have been cons Read More

Background: Nanofluids have huge applications in many areas wherever heat transfer is concerned. The most profits of nanofluids exhibit superior heat transfer characteristics and great energy saving. The nanofluid thermal conductivity depends on several factors like particle size, particle material type, particle volume fraction, particle shape, operating temperature, base fluid material and type of additives. Method: In the Read More

Background: Porous carbon materials are promising candidate supports for various applications. Different approaches have been applied for preparation of various types of porous carbon materials which in the most of them; disordered structures as well as relatively broad pore size distribution are obtained. The most reliable method for preparing of the ordered carbon mesoporous is nano-casting using mesoporous Read More

Background: Despite the progress realized in low-dimensional semiconductors, significant researches are still required for them before they can be used at a large scale mainly with the recent emergence of the surface states and the engineering of two dimensional nanomaterials. The ultra-thin quantum dots are characterized by thickness on the atomic scale, possess high flexibility and multi-functionality in optoelectronic applic Read More

Background: Gold nano-clusters (Au-NCs) are non-toxic bio-markers, with higher potentials as compared to quantum dots, and hence the present work was focused on the synthesis of Au- NCs using Cysteine (Cys) as the reducing and protecting agent. Method: The properties of the resulting Cys-Au-NCs were evaluated through scanning electron microscopy (SEM), as well as FT-IR, fluorescence and UV–Vis spectroscopy. Synth Read More

Background: Mercury pollution has become a serious and enduring threat to the environment. It has affected the organisms along the food chain, including humans. Thus, it is necessary to design an effective mercury removal system to overcome the huge threat of mercury pollution. Our study aim is to optimize the anodization duration of as-prepared WO3-loaded TiO2 nanotubes for improving their photocatalytic mercur Read More

Background: The combination of anticancer drugs in nanoparticles has great potential as a promising strategy to maximize drug efficacies. Gemcitabine (GEM), a nucleoside analogue, and atorvastatin (ATV), a cholesterol lowering agent, have shown anticancer effect with some limitations. Objective: The study aimed to evaluate antitumor activity of the combination therapy of GEM and ATV encapsulated in nanod Read More

Background: The research on use of nanofluids for machining applications has gained more attention for over the past two decades. However there is limited review/data, available on the basis of individual nanoparticles performance, when added as an additive to coolant (cutting fluids)/ lubricant used for machining applications. Hence, this article meticulously attempts to come up with an individual nanoparticle wise revi Read More
