In the present study, the effects of particle size (20 nm or 70 nm) and surface charge (negative or positive) on the pharmacokinetics, tissue distributions, and excretion of ZnO nanoparticles were examined following the administration of a single oral dose to rats. Pharmacokinetic profiles and biodistributions were no…
Although smectite clays have gained much interest in recent years as potential sustained local drug delivery vehicles, they have not been yet utilized or assessed as a local drug delivery device for treatment of periodontal disease. In this paper we showed that unique nanostructure and gel-formation ability of clay ho…
We report the synthesis of a dithienylethene–tetraphenylethene (DTE–TPE) conjugated photochromic fluorophore which simultaneously exhibits aggregation-induced emission and reversible fluorescence switching. Photochromic DTE–TPE turns cyan-blue after 5 s of UV irradiation and exhibits a strong green emission at 520–540…
Herein we describe a low-cost method for fabricating high-performance flexible supercapacitors based on 10 nm-scale MnO2 nanoparticles as active electrode materials. The as-fabricated supercapacitor possesses an electrochemical capacitance as high as 645 F g−1 at a discharge current density of 0.5 A g−1, as well as go…
Nanoparticles are considered as powerful tools in nanotechnological applications. Due to their unique physicochemical properties, their interactions with different biological systems have been shown. Nanomaterials have been successfully used as coating materials or treatment and diagnosis tools. Nevertheless, toxic ef…
The shear rheology of soft particle systems becomes complex at large density because crowding effects may induce a glass transition for Brownian particles or a jamming transition for non-Brownian systems. Here we successfully explore the hypothesis that the shear stress contributions from glass and jamming physics are…
A series of α-Al2O3-supported Ni catalysts with different Ni particle sizes (5–10, 10–20, and 20–35 nm) were prepared and applied in the CO methanation reaction for the production of synthetic natural gas (SNG). The catalytic tests showed that the Ni nanoparticles influenced the catalytic performance in the CO methana…
Nanoparticles (NPs) in the biological environment are exposed to a large variety and concentration of proteins. Proteins are known to adsorb in a 'corona' like structure on the surface of NPs. In this study, we focus on the effects of surface compositional and structural heterogeneity on protein adsorption by examinin…
Due to the extremely low surface tension of oils, the elaboration of superoleophobic surfaces implies the development of well-defined strategies to impede their tendency to spread. Usually, these strategies combine the presence of re-entrant structures (overhang, mushroom-like, T-like structures, etc.) with perfluorin…
The temporal growth of dynamic response during the aging of hectorite clay suspensions containing NaCl with different poly(ethylene glycol) (PEG) concentrations was measured. For each PEG concentration, the dynamic responses at different waiting times were shifted into a master curve against the rescaled frequency, wh…
In this study we investigated the effect of the nozzle type as one of the most important parts of the open-end rotor spinning system on yarn quality. 100% Urfa Region cotton was used for the production of yarns of 20 tex. Experimental studies were made on ten spinning units of a Rieter R1 machine. Five different ceram…
The properties of vortex yarn made from 100% polyester fibre with different fibre finenesses and spinning speeds were studied. Four different fibre finenesses (0.9, 1.1, 1.3 and 1.5 dtex) were used to produce yarns of 20 tex polyester vortex yarn with five different delivery speeds (320, 340, 360, 380 and 400 m/min),…
This research is focused on the analysis of adsorbed CH4 intermediates at oxidized Pd9 nanoparticles supported on γ-alumina. From first-principle density functional theory calculations, several configurations, charge transfer and electronic density of states have been analyzed in order to determine feasible paths for…
In the present experimental study, the precipitation of basic yttrium nitrate from aqueous solutions allowed the optimization of conditions for the preparation of loosely aggregated Y2(OH)5NO3 1.5H2O, the thermal decomposition of which, under controlled annealing, permitted the synthesis of yttria nanoparticles with d…
The aim of the paper is to present the basic concepts of advanced high strength dual phase steels for automotive applications, including the design of chemical composition, microstructure and mechanical properties development during thermo-mechanical processing as well as characterization production technology and the…
The article presents a comparative analysis of the properties of cotton yarn spun on three pneumatic compact spinning systems Rieter® K-44, Suessen® Elite and Toyota® RX-240. Combed compact cotton yarn with a linear density of 10 tex was spun on these compact spinning systems using medium staple cotton. The roving pro…
We have prepared various non-aqueous systems of emulsions, foams, liquid marbles and polymeric materials stabilised solely by either dichlorodimethylsilane (DCDMS)-modified amorphous silica or organo-modified Laponite clay nanoparticles.
The strength development of self-compacting mortars (SCM) containing calcined silt (CS) and ground brick waste (GWB) was investigated. The variables are the nature of addition (CS and GWB) in the binder and the heat curing at different temperatures (20 ºC and 60 ºC) at 7 and 14 days of curing. Two temperatures 20 and…
Indigenous design and fabrication horizontal of electrospinning set up was developed to facilitate with double drum conveyor belt system to make ease in harvesting nanofibers rapidly. As a bench mark study, organic-inorganic nanofiber composite was synthesised employing our indigenous electrospinning set up. The aqueo…
New environmental laws have restricted the use of hardwood trees in overhead power lines structures, such as, poles and cross-arms, leading companies to seek alternative materials. Reforested wood coated with polymeric resin has been proposed as an environmental friendly solution, with improved electrical properties a…
