The electrochemical behavior of 304-stainless steel in solutions with different pH values and chloride concentrations was investigated by potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and a nonlinear Mott-Schottky analysis method. The results showed that the corrosion behavior of 304-stai…
p-type NiO nanofibers have been synthesized from a simple electrospinning and sintering procedure. For the first time, p-type nanofibers have been electrospun onto a conductive fluorine doped tin oxide (FTO) surface. The properties of the NiO nanofibers have been directly compared to that of bulk NiO nanopowder. We ha…
Abstract Heteropoly compounds (HPCs) have already proved their high potential for the clean synthesis of commercially valuable chemicals. However, the use of HPCs for the transformations of terpenic substrates became a research topic only about 20 years ago. Terpenes, natural products available from essential oils, ar…
Biocompatible nanocarriers conjugated with magnetic nanoparticle, doxorubicin and poly(ethylene oxide) (PEG) motif have been designed ( PVLPEG-PVLDOXI-PCL-PHOS ) to create a magnetic vector under magnetic field. Acylhydrazine linker is used to release the drug exactly at the mild acidic conditions resembling the pH of…
Although gold nanorods (GNRs) have been investigated extensively for optical hyperthermia therapies, the synthesis of rods is far from ideal. In this report, we optimized the synthesis of gold nanorods using hydroquinone as a reducing agent. Compared with the GNRs prepared by traditional ways, the as-synthesized rods…
Abstract In situ X-ray synchrotron tomography is an excellent technique for understanding deformation behavior of materials in 4D (the fourth dimension here is time). However, performing in situ experiments in synchrotron is challenging, particularly in regard to the design of the mechanical testing stage. Here, we re…
This article reviews recent numerical studies of thermal transport in graphene, with a focus on molecular dynamics simulation, the atomistic Green’s function method, and the phonon Boltzmann transport equation method. The mode-wise phonon contribution to the intrinsic thermal conductivity (κ) of graphene and the effec…
Airborne formaldehyde, which is a highly problematic volatile organic compound (VOC) pollutant, is adsorbed by polymeric amine-incorporated silicas (aminosilicas), and the factors that affect the adsorption performance are systematically investigated. Three different types of polymeric amines 1) poly(ethyleneimine) br…
Although recognized as overly conservative, metoprolol is currently the common low/high BCS permeability class boundary reference compound, while labetalol was suggested as a potential alternative. The purpose of this study was to identify the various characteristics that the optimal marker should exhibit, and to inve…
Abstract BACKGROUND The present study explores the synthesis of chitosan–metal nanocomposites in view of their increasing application as antimicrobial material. RESULTS Chitosan nanoparticles were prepared by ionic gelation between chitosan and sodium tripolyphosphate. Copper sulphate hydrate ( CuSO 4 . 5H 2 O ) and z…
Nanosized particles can exhibit unexpected properties different from those of the original bulk material. The basic premise is that properties can dramatically change when a substance's size is reduced to the nanometre range. The applications of nanoparticles, e.g. carbon black or some finishing agents in the textile…
We propose a method for the synthesis of a colloidal ZnO solution with poly(N-vinylpyrrolidone) (PVP) as stabilizer. Stable colloidal solutions with good luminescence properties are obtained by using PVP as stabilizer in the synthesis of ZnO nanoparticles by a sol-gel method assisted by ultrasound. Nanoparticles with…
Two chromo-fluorogenic probes, each based on the boron dipyrromethene core, have been developed for the detection of nerve-agent mimics. These chemosensors display both a color change and a significant enhancement of fluorescence in the presence of diethylcyanophosphonate (DCNP) and diisopropylfluorophosphate (DFP). N…
Exploring thermal transport in graphene–polymer nanocomposite is significant to its applications with better thermal properties. Interfacial thermal conductance between graphene and polymer matrix plays a critical role in the improvement of thermal conductivity of graphene–polymer nanocomposite. Unfortunately, it is s…
We have investigated the structural, mechanical and lattice dynamical properties of ZrW2 and HfW2 compounds in cubic C15 (space group Fd-3m), hexagonal C14 (space group P63/mmc) and C36 (space group P63/mmc) phases using generalized gradient approximation within the plane-wave pseudo-potential density functional theor…
Molecular dynamics simulations are used to study CO adsorption on Ag nanoclusters ranging from 38 to 500 Ag atoms, supported on carbon nanotube. Each nanocluster was simulated under various pressures of CO gas at different temperatures. The absolute value of enthalpy of adsorption was calculated for all of the nanoclu…
In this study, it was aimed to investigate the mechanical, thermal, and morphological properties of PA6 hybrid composites containing talc and wollastonite. Talc and wollastonite filled single and hybrid composites were prepared with melt compounding in a twin screw extruder. The filler content was 40% by weight and th…
This paper presents an electrochemical review on the corrosion behavior of iron and steel in bicarbonate and carbonate solutions. The mechanisms of dissolution and passivation are at first consolidated. The significance of microstructure and alloying composition and those of bicarbonate, carbonate, and chloride, in ae…
This paper investigates the thermal conductivity of silicene nanosheets (SiNSs) via molecular dynamic simulation. It shows that the thermal conductivity of pristine SiNSs is about 25–30 W mK −1 and exhibits anisotropic behaviour. Moreover, it is found that isotopic doping is efficient in reducing the thermal conductiv…
Results of an experimental and computational study of CO 2 adsorption onto a CeO X (100) thin-film surface are reported. For both oxidized CeO 2 (100) and reduced CeO 1.7 (100), a 5 L dose of CO 2 at 180 K resulted in mainly carbonate ([CO 3 ] 2– ) on the surface with a minute amount of physisorbed CO 2 that desorbed…
