Since the first experimental demonstration of the negative-refractive-index metamaterial by Shelby et al. in the early 2000s, metamaterials have experienced great interest from research community, resulting in an increasingly large number of publications. Truly three-dimensional (3D) metamaterials, which are able to i…
Research of possibility of management of morphological parameters of arrays nanoparticles Au (form, the size, density of superficial distribution) of the thin films of ZnO received on a surface by method of the pulse laser deposition (PLD) with subsequent annealing in the inert atmosphere was conducted. It was experim…
Silicon (Si) based nanomaterials have the potential to revolutionize the microelectronics industry by introducing desirable nanoscale properties into electronic components without compromising the material composition. They have also been proposed as a greener alternative for many Group III-V and II-VI semiconductors.…

SMILE un Femto LASIK ir jaunās operāciju metodes, ko visbiežāk pielieto mūsdienu refraktīvā ķirurģijā. Operāciju laikā tiek pielietoti divi dažādi lāzeru veidi, ja tie bojātu radzenes endotēlija slāni, tad pacientiem pēc operācijas periodā pastāvētu iespēja attīstīties radzenes tūskai un redzes asuma samazināšanai.\n…
Razpoke razlicnih oblik in velikosti sodijo med najbolj razsirjene poskodbe na bitumeniziranih voziscih. Osnovni vzrok za nastanek razpok v bitumenizirani plasti je narascanje nateznih in strižnih napetosti vse do tocke prekoracitve trdnosti materiala. Eksperimentalni del disertacije zacenjamo z laboratorijskimi presk…
Several series of quaternary chalcogenides were synthesized by high temperature reactions and their crystal structures were determined by X-ray diffraction methods. Differences in electronic structure were examined by X-ray photoelectron spectroscopy (XPS) and X-ray absorption near-edge spectroscopy (XANES). For some…
Hemolytic uremic syndrome (HUS) is a potential life-threatening condition caused by infection with Shiga toxin-producing Escherichia coli O157:H7. There are two major types of Shiga toxins, namely, Shiga toxin 1 (Stx1) and Shiga toxin 2 (Stx2), of which, Stx2 is clinically most closely associated with enterohemorrhagi…
The aim of this study is to examine structural and magnetic properties of Ni50Mn34-xCuxIn16 (x = 1.3 and 1.5) Heusler alloys obtained for both bulk and ribbon and the magnetocaloric properties based on the results of the magnetic characteristics. It is expected that the magnetization and the martensitic transition tem…
以城市污水处理厂产生的污泥为原料,对其进行焚烧得到污泥焚烧灰。在对污泥焚烧灰进行表征的基础上,研究了利用污泥焚烧灰对水中Cd^2＋的吸附。结果表明,吸附效率随吸附时间、污泥焚烧灰投加量和初始pH的增加而增加;而温度的影响不明显。在吸附时间为80 min,污泥焚烧灰投加量为10 g/L,初始pH为5～7,温度为30℃的最佳工艺条件下,当Cd^2＋浓度低于10 mg/L,污泥焚烧灰对水中Cd^2＋的去除率可达99%以上。废水中的Cu^2＋会对Cd^2＋的吸附产生抑制作用,而Cr^6＋影响微弱。污泥焚烧灰对Cd^2＋的吸附过程符合Langmuir吸附等温式,吸附过程主要是物理吸附,吸附量可达17.94 mg/g。
Lot of experimental work has been done on the polytypism of CdI2 and a vast structural data is now available, It is a theoretical fact that all polytypes consist of basic structures 2H and 4H.In this paper, it has been established that how the impurities present in the starting material are responsible for “why some o…
Zirconium alloys are widely used in nuclear power plants as cladding material to contain the fission fuel in the reactor cores. A limiting factor for fuel longevity is the corrosion property of the zirconium alloys. The main corrodent in the reactor core is water. Ideally, the oxidation process of zirconium alloys wit…
Uporaba biorazgradljivih prirodnih ili sintetskih polimera kao ambalažnih za okolis prihvatljivih materijala sve je vise u porastu. Netoksicnost i visoka elasticnost omogucuje im siroku primjenu u prehrambenoj industriji u cilju zastite kvalitete hrane, u medicini za izradu medicinskih pomagala, u farmaceutskoj indust…

Pd/TiO2 particles were prepared by wet impregnation for aerobic benzyl alcohol oxidation. Catalysts were prepared by the impregnation of 10 wt% palladium on TiO2 after calcination at various temperatures. The surface areas of the catalysts were changed with calcination temperature. The catalyst calcined at 300 °C poss…
The kinetics of the thermal decomposition of Athabasca vacuum residue (AVR) has been studied by thermogravimetric analysis. Three heating rates of 0.5, 10 and 25 K/min were used to investigate the consistency of kinetic parameters. The Weibull and Gaussian distribution functions were found to be the best distribution…

Verkleinert man den Durchmesser von Fasern bis in den Nanobereich, so verändert man ihre Eigenschaften. Die offensichtlichste ist die Vergrösserung der Faseroberfläche, die sich zur Steuerung von Vorgängen an Oberflächen nutzen lässt – von der Benetzbarkeit über die kontrollierte Abgabe und Aufnahme von Geruchsstoffen…
Visible absorption and circular dichroism measurements of the title compounds, conducted in aqueous solution at neutral pH, showed that both ligands maintained their “glycine-like” configuration, i.e. they were bonded to Cu(II) via the amino nitrogen and carboxylato oxygen atoms, and formed bis-complexes.[1] This coor…
Bone tissue is a complex structure with the capacity to self-regenerate and responsible for different functions in our body. However, when bone integrity is disturbed, its self-regenerative capacity is lost. The available treatments are based on bone grafts and other bone substitutes which possess several limitations.…
