Zinc-doped InP(Zn) colloidal quantum dots (QDs) with narrow size distribution and low defect concentration were grown for the first time via a novel phosphine synthetic route and over a wide range of Zn doping. We report the influence of Zn on the optical properties of the obtained quantum dots. We propose a mechanism…
Graphene continues to attract growing attention with its exceptional physical and mechanical properties, and more than one layer graphene structure with an orientation mismatch is often involved in practice. Using molecular dynamics (MD) simulations, we report the wettability of water droplet on a misoriented graphene…
Abstract Widespread lateritized ultramafic rocks in the southern part of the Muratdağı region of Turkey constitute a significant source of Ni-Cr-bearing ore with economic potential. However, no mineralogical or geochemical characterizations of these important materials have been performed previously. The aim of the pr…
Using in-situ Kelvin probe force microscopy (KPFM) to measure surface potential, we investigated the time-dependent work function evolution of solution-processed graphene oxide (GO) under ultraviolet (UV) irradiation. We found that the work function of GO exposed in UV shows a notable decrease with increasing irradiat…
The evolutions of phase constitutions and mechanical properties of a β-phaseTi–36Nb–5Zr (wt%) alloy during thermo-mechanical treatment were investigated. The alloy consisted of dual (β+α″) phase and exhibited a double yielding phenomenon in solution treated state. After cold rolling and subsequent annealing at 698 K f…
It has been newly discovered that by simply altering the applied voltage, the resultant electrospun prolamin protein fabrics can rapidly (within 30 s) form either flat sheets or self-rolled tubes when immersed in water. This phenomenon opens up many potential biomedical applications for drug delivery. The morphology a…
To investigate the shape and confinement effects of the terminal siloxane groups on the self-assembled behavior of molecular arrangements in hydrogen-bonded (H-bonded) bent-core complexes, four H-bonded bent-core complexes S1, P1, C4, and P8 with string-, ring-, and cage-like siloxane termini (i.e., linear siloxane un…
Athermal two-dimensional granular systems are exposed to external mechanical noise leading to Brownian-like motion. Using tunable repulsive interparticle interaction, it is shown that the same microstructure as that observed in colloidal suspensions can be quantitatively recovered at a macroscopic scale. To that end,…
X-ray absorption spectroscopy facilitated by state-of-the-art synchrotron radiation technology is presented as a powerful tool to study nanoscale systems, in particular revealing their static element-specific magnetic and electronic properties on a microscopic level. A survey is given on the properties of nanoparticle…
When two microemulsions are put in contact in the gravity field along a horizontal contact line, cross-diffusion can trigger the transport of one species in the presence of a gradient in concentration of another species. We show here theoretically that such cross-diffusion effects can induce buoyancy-driven convective…
Generating machines of electricity, using combustion engines and generate a great amount of residual thermal energy from the exhaust gases. This residual thermal energy can be converted into usable electricity using thermoelectric generator (TEG), which are manufactured cells with semiconductor materials employing the…
Undoped and Mn doped SnO2 prepared by co-precipitation method exhibits nanocrystalline nature with prominent peaks along ( All the prepared samples are nanocrystalline with crystallite size lying in the range of 4.85.6 nm. The prepared SnO2 nanoparticles exhibit single tetragonal crystalline phase. The high resolution…
Abstract In October of 2014, a meeting jointly organized by the EU Nanosafety Cluster and the COST Action TD 1204, was held on the beautiful island of Ortygia in Syracuse (Sicily). The meeting was specifically conceived to give the opportunity to young researchers in the field of nanotoxicology to present and discuss…
A new method to make SMA is developed by using SBS modified asphalt when the coarse aggregate steel slag and the fine basalt aggregate are selected respectively. The Mix Proportion is 1#(16-9.5mm, steel slag):2#(9.5-4.75mm, steel slag):3#(3-4.75mm, basalt):4#(3-0mm, basalt):5# (mineral powder)=38%:36%:8%:8%:10%.The op…
Knitted fabrics are preferred as clothing materials because of of their outstanding comfort quality. 16 plain knitted fabric samples were produced from 4 combed ring spun yarn of linear densities 29.5 Tex, 23.6, Tex 19.7 Tex and 17.4 Tex and 4 different stitch lengths from each yarn linear density were selected for th…
This paper describes the preparation of a piezoelectric glass ceramic material from potassium sodium niobate (K 0.5 Na 0.5 NbO 3 ; KNN) using a novel melting method. The effects of the subsequent heat-treatment on the optical, thermal, electrical, and mechanical properties of the material are carefully examined, and i…
In this paper the effect of different types of coatings on durability increase of the tool for surface plastic deformation is considered. Wide burnishing processing with coated tool was selected as such research was performed for the first time. The influence of the type of coating on the tool durability has been expl…
Grafting polymerization was a valuable method for the modification of the chemical and physical properties of polymer surfaces. In this paper, the grafting of cationic vinyl monomer with quaternary ammonium groups, methacryloxyethyltrimethyl ammonium chloride (DMC), onto the isotactic polypropylene (iPP) granule was p…
The aim of the research was to investigate the influence of strontium on the structure thin films La1-x SrxCoO3 (x=0; 0.1, 0.2). The LaCoO3 and LaCoO3 doped by Sr films were grown by pulsed laser deposition (PLD) on Si [100] substrate using an Excimer KrF (= 248 nm). To characterize the structure and morphology of th…
