Abstract : At the nanoscale, the optical, electrical, and catalytic properties of a material depend on its size and shape. Therefore, synthesis of nanoparticles with controlled size and shape is important for their application in biosensors, photonics, and other optoelectronic devices. Whereas the effect of size on th…
Optoelectronic functional molecules are usually used as films or aggregates. The discovery of aggregation induced emission (AIE) molecular systems supplies a novel method to solve the problem of aggregation-induced fluorescence quenching (ACQ). In this paper, we summarized a series of AIE molecules developed in our gr…
In this study, unsaturated polyester resin (UPE) and Natural rubber (NR) were used to prepared binary polymer blend (UPE/ NR) with weight ratio (95/5) %. The present paper investigates the diffusion behavior of three environmental groups , the first group is different types of water included (distilled water, tap wate…
A comparative study of the defect formation and changes in the lifetime of nonequilibrium minority charge carriers in silicon while gettering the iron impurity with the use of a combined getter “porous silicon layer + aluminum film” is carried out. It is shown that, while annealing specimens with no getter layer, iron…
Structural, optical, and electrical properties of InSe and GaSe single crystals diffusely intercalated with ethanol have been studied. The X-ray analysis confirmed that ethanol molecules become introduced into the interlayer space of samples. The dependences of the energy position of the main exciton maximum and a hal…
Films of Poly Methyl Methacrylate (PMMA) doped by (1%) Potassium Iodide (KI) have been prepared using casting method at room temperature. Optical properties were investigated for different thicknesses by using spectrophotometeric measurement of absorption reflection transmission in the wave length range (200-800) nm.…
We demonstrate theoretically and experimentally that electrically gated single-layer graphene can be used to inductively tune the infrared optical response of Fano-resonant meta-surfaces. Several implementations will be introduced: graphene of the meta-surface, graphene directly under the meta-surface, and graphene se…
The treatment of waste gases as well as solid and liquid wastes is important activity for environmental protection. Recently, with the tightening emission limits, the pressure to reduce emissions, especially the volatile organic compounds (VOCs), has increased. The reason is not only the impact of these emissions on t…
The presented paper was focused on the experimental investigation of a promising combustion technology, namely the oxygen-enhanced combustion (OEC). This technology is used in those industrial heating applications that require increased productivity, higher heat transfer efficiency, improved flame characteristics, red…
The exposition of concrete and cement composites to the aggressive environment is resulting in damages in the structures before the expected service life. Prolonging the service life of concrete composites through enhancing the mechanical and durability properties has gained great importance in recent years. It is pos…
The present study focuses on the characterization and evaluation of mechanical properties and resistance to impact of composites reinforced with flax fibres combined to an epoxy or PPMA matrix. A better understanding of this behaviour allows the prediction of long-term properties to assess the viability and long-term…
The influence of yarn construction parameters (yarn count and yarn twist) and quality of cotton fibres in terms of HVI parameters on yarn hairiness has been studied. The Uster Tester 4 and Zweigle G 567 are used for yarn hairiness investigation. The statistical methods (correlation analysis and principal component ana…
The reactive brilliant blue was chosen as the probe pollutant. Fe(NO3)3 concentration, MnSO4 concentration, urea concentration, water bath temperature, calcined temperature and time were as influencing factors, the process parameters of homogeneous precipitation method was optimized for the preparation of bimetallic h…
The transcellular process of coumarin 6 (C6) loaded poly(ethyl ethylene phosphate)-co-poly (epsilon-caprolactone) (PEG-PCL) micelles on Madin-Darby Canine Kidney (MDCK) epithelial cells was investigated. C6 loaded PEG-PCL micelles were prepared using the thin-film hydration method. The size of the micelles was charact…

A blow-off tool has allowed for the measurement of the cumulative distribution of charged toner particle adhesion to a polymer belt. The tool methodology and design are described. The tool is calibrated to obtain the adhesion force using two different techniques, and the measured values agree well with published value…
The turning on and off of a convex scatterer can be used to store information in digital versatile disc (DVD) or Blu-ray technology. In addition, the distance between scatterers can be used as information, if it is precisely measured. Using a recently developed method, a single Fourier transformation of a diffraction…
Abstract An increasing variety of different nanostructured materials including bionanomaterials are used. During synthesis, but also during use of nanostructured materials along their life-cycle, nanostructured materials and engineered nano-objects (ENO) – may be released into the environment. They will follow differe…
