Opis:
Over the last few years there have been many studies of GaAs layers grown at low temperatures (180-300°C), so called LT GaAs. The interest in LT GaAs was motivated by the potential application of 600oC annealed LT GaAs in microwave and fast optoelectronic devices because of its short photocarrier lifetime, reasonable mobility and high resistivity. These properties are associated with the nonstoichiometry of LT GaAs. Recently, studies of comparable material, nonstoichiometric GaAs produced by arsenic ion implantation have been initiated. There is still a strong controversy as to whether the arsenic antisite (As$\text{}_{Ga}$) or arsenic precipitates are responsible for unique electrical properties of both materials. This paper presents the results of structural and electrical studies of high energy As implanted GaAs and comments on relationships between the structure and the resulting electrical properties.

Opis:
Gold films of thicknesses 150-300 Å were deposited on quartz substrata using vacuum evaporation technique. Spectrophotometric measurements of transmission T and reflection R at normal incidence were performed in the range 0.4-3.0 µm. The real and imaginary parts of the complex refractive index ñ were determined using a developer algorithm bashed on Murmann's exact equations. The accuracy in the determined n and k was found to be ±6.0% and ±1.6%, respectively. The dispersion curve of n slowed an anomalous dispersion in the visible region characterized by a peak at λ = 0.840 µm. The dielectric constants were calculated and presented. The Drude model parameters ω$\text{}_{p}$ and ω$\text{}_{τ}$ and d.c. conductivity were determined and compared. The results showed that such parameters could be obtained from free-electron analysis for the near IR experimental results and the intraband transition contributes significantly to the dielectric functions.

Opis:
The studies of transport and optical properties of GaAs implanted with high arsenic doses were performed. As-implanted samples showed hopping conductivity and the exponential absorption tail in the near-IR region. Both effects were probably caused by the amorphization of implanted layer. Using EPR measurements it was found that arsenic antisite defect with high local strain field was created during implantation. Annealing of implanted layers at 600°C led to substantial removal of amorphization, decrease in absorption coefficient and hopping conductivity leading to resistive samples. The possible model of such behaviour may be similar to the one of suggested for low temperature GaAs layers.

The measurements of cold rolled nickel alloys with 1 at.% of Ge, Zn, In, Zr, Pb and additionally Ti and Sb by positron lifetime and Doppler broadening techniques have been done. Monovacancies were a dominating type of defects in the alloys. The authors of the present paper connect the differences between the annihilation parameters of the investigated samples with the existence of the vacancy-impurity atom pairs. A direct proportionality between the vacancy lifetime and the product of vacancy-impurity binding energy and atomic radius of impurity atom has been found.

The analysis of low and middle momentum parts of Doppler spectra for investigated alloys reflects the annihilation of positrons with admixture electrons. There is no distinct signal of annihilations with admixture electrons from the positron lifetime data for well-annealed samples.

Electrorheological (ER) fluids belong to the broadly studied class of so called "intelligent materials" whose properties are sensitive to external stimuli. The ER fluids increase their viscosity upon application of an electric field. This paper reports the results of electrorheological experiments and describes a synthetic procedure leading to an ER suspension exhibiting predetermined characteristics. The fluid was designed for application in a prototype ER clutch.
Ciecze elektroreologiczne (ER) należą do intensywnie badanej grupy tak zwanych inteligentnych materiałów, których właściwości można modyfikować za pomocą czynników zewnętrznych. Cechą charakterystyczną cieczy ER jest gwałtowny i odwracalny wzrost lepkości pod wpływem przyłożonego pola elektrycznego. Niniejsza praca zawiera wyniki eksperymentów elektroreologicznych i opis syntezy prowadzącej do otrzymania zawiesiny elektroreologicznej spełniającej określone parametry użytkowe.

Opis:
We report the synthesis of PbF2:Er3+ particles using a hydrothermal method. The structure and upconversion emission properties of the products are investigated by scanning electron microscopy, X-ray diffractometer, Raman spectrophotometer and fluorescence spectrometry. An increase in Er3+ concentration in the crystals changes the PbF2 structure from a mixed phase to a cubic phase and decreases the grain size to nanoscale levels. Enhanced upconversion efficiency is achieved after annealing resulted from the formation of the cubic phase and the increase of grain size. The optimal Er3+ concentration is found to be 4% after annealing, and applied to the back of a bifacial silicon solar cell, maximum external quantum efficiencies of 0.38% and 0.79% are respectively obtained under 0.77 W/cm2 laser excitation (1560 nm) and AM1.5 + laser co-excitation.

Pulsed laser ablation in ethanol at room temperature with laser fluence 4.62 J/cm2 was employed to synthesize pure zinc oxide (ZnO) and Er- doped ZnO nanocolloidal suspension. The structural properties were determined by using x-ray diffraction (XRD) method and was confirmed its hexagonal wurtzite structure. The photoluminescence spectra (PL), AFM and FTIR measurement of the synthesized pure and Er-doped ZnO is carried out. The photoluminescence spectra measurements show that all the samples have ultraviolet emission and green emission and the surface granular morphology. The FTIR spectra indicate the existence of Zn-O, Er-O-Er and Er-O stretching modes. Al/ZnO/P-Si/Al and Al/Er-ZnO/P-Si/Al photodetectors hetrojunction has two peaks of response located at 650 nm for and 790 nm and the first peak shifted to 550nm for the doped hetrojunction with max sensitivity 0.7A/W. The maximum specific detectivity is 4.3×1012 W-1•cm•Hz-1 and 3×1012 W-1 •cm•Hz-1 for undoped and doped hetrojunctions respectively. The values of the built-in potentials 0.9 volt for Al/ZnO/P-Si/Al heterojunction and 0.6 volt for Al/Er-ZnO/P-Si/Al hetrojunction.

Opis:
The Dayet Er Roumi lake located in the biogeographic zone of the central meseta belonging to the province of Khemisset, constitutes the only permanent natural lake of low altitude in Morocco. The lake’s water body is the essence of the existence of this natural and environmental space. The objective of the present study was on the one hand to evaluate the current state of the bacteriological quality of the waters lake Dayet Er Roumi, and on the other hand to define the risks of the pollution waters lake, and its origin. In order to carry out this work well, the evolution of the bacteriological parameters of the waters lake during the period from October 2020 until September 2021 was studied at the level of four stations of sampling. The obtained results showed that the waters of Dayet Er Roumi are confronted with a strong pressure generated by the discharges of domestic waters of the neighbouring agglomerations and also by activities of natural, agricultural and tourist origin. Indeed, the bacterial load is expressed by a high load of bacteria indicative of fecal contamination which varies between 50 and 346∙103 CFU/1 ml for total aerobic mesophilic flora (TAMF) at 22 °C, 6 and 72∙103 CFU/1 ml for TAMF at 37 °C, 15 and 62∙103 CFU/100 ml for total coliforms (TC), 0 and 4350 CFU/100 ml for faecal coliforms, 0 and 16 350 CFU/100 ml for faecal streptococci, 1 and 13∙103 CFU/20 ml for sulphite-reducing anaerobes, 38 and 22 680 CFU/100 ml for Staphylococcus aureus and between 160 and 33 600 CFU/100 ml for Pseudomonas aeruginosa. These results largely exceed the Moroccan standards for the water intended for irrigation. They could be the cause of possible contamination of irrigated crops as well as groundwater in the region, and consequently have repercussions on human health.

Opis:
Holmium, erbium and lutetium citrates can be synthesized by transforming freshly precipitated holmium, erbium and lutetium hydroxides in the citric acid solution under the hydrothermal conditions (above 100 ℃) after 3 days of reaction. In this paper in order to determine the synthesis conditions, the hydroxide and citrate stability areas of selected lanthanides were compared. The studies of the structure of the obtained holmium citrate, erbium and lutetium samples showed that these compounds crystallize in a monoclinic system. The crystallite sizes determined by the HalderWagner method were 67.8 ± 8.0nm, 103.7 ± 4.5nm and 68.1 ± 4.2nm, respectively for the holmium citrate, erbium citrate and lutetium citrate samples. The shifts of the hydroxyl and carboxyl groups of citric acid in the FTIR spectrum indicate the interactions of both groups with holmium, erbium and lutetium cations. Then the obtained samples were subjected to the analysis of composition, and their particle size distribution was determined.

Opis:
Yb3+/Er3+/GZO ceramics have been synthesized with high temperature solid-state method. The phase and structure of the Yb3+/Er3+/GZO ceramics were characterized by X-ray diffraction (XRD). The XRD pattern that following ions Yb3+, Er3+ and Ga3+ were well doped into the ZnO lattice. Effi cient visible up-conversion (UC) red and green emission were observed under 980 nm excitation. The mechanism of the UC luminescence is investigated on the basis of the UC luminescence emission spectra, the power curve and energy level diagram. The infl uence of doping ions to the intensity ratio of red to green is analyzed and high purity of red light (red/green = 29.9) is fi nally obtained.

Opis:
Erbium oxide (Er₂O₃) coating is one of the promising methods to restrict tritium permeation and the magneto hydrodynamic pressure drop for advanced breeding blanket systems. Er₂O₃ coating layer on large interior surface area of metal pipe is deposited by using metal organic chemical vapor deposition process. In this work, the influence of Cu²⁺ ion irradiation on microstructure of Er₂O₃ coating layer on stainless steel 316 (SUS 316) substrate by metal organic chemical vapor deposition methods was investigated using scanning electron microscopy, transmission electron microscopy observation and X-ray diffraction analysis. Microstructure observation of Er₂O₃ coating was carried out after 0.00-1.50 dpa Cu²⁺ ion irradiation at 298 K and 773 K. Scanning electron microscopy observation of the surface area on Er₂O₃ thin film revealed the crack generation on surface after Cu²⁺ ion irradiation. X-ray diffraction peaks were identified in Er₂O₃ after Cu²⁺ ion irradiation transmission electron microscopy observations, the formation of interlayer between Er₂O₃ coating and SUS substrate was confirmed. According to transmission electron microscopy-energy dispersive spectroscopy, the interlayer includes Fe and Cr.

Opis:
There is an increasing interest in effective methods for building consumer involvement on a mass scale. This paper offers an interdisciplinary theoretical framework for consumer involvement analysis and forwards an anthropological approach to this issue. It uses categories of play and communitas to examine cultural dynamics underlying consumer involvement. It summarizes and extends theoretical understanding of the topic and provides numerous examples from contemporary marketplace such as Heineken Open’er Festival and Volkswagen ‘Fun Theory’ initiative. Several research propositions are formulated for future empirical endeavors and implications for practice are defined.
