A 91×91 complete energy matrix of 4f2configuration ion Pr3+in triagonal crystal fieldC3hhas been constructed based upon the combination of Racahs irreducible tensor with Slaters wavefunctions. Thus, the Stark energy levels of Pr3+in trichlorides LaCl3have been calculated. The calculation result shows that the complete…
Monodisperse porous polystyrene microspheres were prepared with the mixed solution of ethanol and water as dispersion medium and poly (vinylpyrrolidone) was used as dispersant. The even size of microspheres prepared at optimal process was about 1μm. Photochromic microspheres were obtained using polystyrene microsphere…
Proflavine wool with silk ‘tie-overs’ is used commonly to secure a skin graft. Our new strategy employs a surgical steel wire suture that can be twisted down to secure the graft without the need for multiple ties. Figure 1A shows the graft over the defect, and Figures 1B and 1C show the steel sutures used as simple lo…
We report on the reduction of the thermal conductivity in ultra-thin suspended Si membranes with high crystalline quality at room temperature. A series of membranes with thicknesses ranging from 9 nm to 1.5 μm was investigated using Raman thermometry, a novel contactless optical technique for thermal conductivity dete…
Several kinds of rubbers used for fabric expansion joints were studied by Thermogravimetric analysis under inert atmosphere before and after artificial accelerated thermal aging. The results showed that because of the difference of the chemical structures, the rubber aging is different. And the thermal stability of Po…
An innovative experimental equipment allowing to study the sputtering induced by ion beam irradiation is presented. The sputtered particles are collected on a catcher which is analyzed in situ by Auger electron spectroscopy without breaking the ultra high vacuum (less than 10(-9) mbar), avoiding thus any problem linke…
The nature of doping acid play important role on the stability of conductive polyaniline (PANI). Many recent investigations have focused on different organic acids. Most organic acids are expensive and difficult to synthesize. According to industrial application, it is important to quantify the stability of conductive…
Chromium slag is a hazardous waste, and its high‐value‐added comprehensive utilisation would be advantageous. High refractive index thin films were prepared on glass substrates by a hydrothermal method from chromium slag with different mineralisers. The samples were characterised by inductively coupled plasma, X‐ray d…
We present the comparative study of EM interference shielding effectiveness (EMI SE) in Ka-band (26-37 GHz) provided by (i) epoxy resin composites filled with low concentration (0.25-2.0 wt.%) of carbons of high surface area (such as single-walled and multi-walled carbon nanotubes, exfoliated graphite, carbon black);…
In this paper, a highly-selective filter based on the composite right/left-handed transmission line (CRLH-TL) theory is presented .It is realized by replacing the traditional shunt inductive loading with a series LC resonator to ground. An attenuation-pole can be introduced by replacing the shorted-stub with a open st…
Multi-extreme THz ESR measurements have been performed on Cr-jarosite, which is an ideal model substance of highly frustrated kagome antiferromagnet. The analysis of antiferromagnetic resonances observed at 1.9K revealed the Dzyaloshinsky-Moriya interaction, which plays an important role on the ground state.
Abstract We developed an 8‐in. VGA flexible OLED display by integrating IGZO‐TFTs and novel highly efficient phosphorescent OLEDs. The emitting layers in red OLEDs using a beryllium complex as a host material and a platinum complex as a guest material exhibited low driving voltage, high luminous efficiency, and high s…
From June 3–5, 2013, the Swiss Federal Laboratories for Materials Science and Technology (EMPA) and the Swiss Light Source held an international workshop on soft X-rays and electrochemical energy storage and converters at EMPA in Dübendorf, Switzerland. A total of 30 scientists from Europe, India, Korea, and the Ameri…
Coupling of localized surface plasmon resonances results in singular effects at the void space between noble metal nanoparticles. Here, we present an approach that allows to produce raspberry-like nanoclusters in which metal nanoparticles are in close interaction. Two types of architectures based on isotropic or aniso…
This paper reviews the history of discovery and the study of the nature of the high-quality natural modes existing on periodic arrays of sub-wavelength scatterers as specific periodically structured open resonators. Here, the arrays can be finite and infinite, and their elements can be dielectric and metallic. These g…
In order to obtain a novel liquid crystal compound with trifluoromethyl substitutent, Sonogashira coupling reaction was used to synthesize the mesogenic compound based on tolane. Firstly, 1-iodo-4-trifluoromethyl-benzene was modified with acetylene groups, and then coupled with iodo amyl biphenyl through Sonogashira r…
Discotic liquid crystals (DLCs) are typically described as disc-shaped molecules with rigid aromatic core and flexible peripheral chains. However, many nondiscoid molecules such as halfdisc shaped have been studied considerably in an attempt to develop new types of core architecture for forming columnar mesophases. He…
In this work we analytically derive the expression of the dipole matrix elements for the photoionization process of a singe phosphorus donor atom embedded in silicon upon irradiation by linearly polarized optical pulses at different incidence angles relative to the bulk crystallographic axes. The derived expressions e…
This paper introduces a method to obtain the excitation characteristics of instrument voltage transformers without parasitic influences from secondary side measurements. The effective winding capacitance of instrument voltage transformers (IVT) is modeled and measured. The capacitive current is subsequently subtracted…
Octyl trimethyl ammonium chloride (OTMAC) is a very efficient accelerant for reactive dyes on dyeing silk. In order to understand the accelerating mechanism, the interaction between dye molecules and OTMAC molecule was studied in this paper. The results showed that the DTMAC made the dye molecules assembled and the pa…
