Thermo-elastic analysis of a functionally graded spherical shell with piezoelectric layers under the effect of thermo-electro-mechanical loading is carried out. Material properties of the shell are assumed to be graded in the radial direction according to a power law function, while the Poisson’s ratio is assumed to b…
The present study describes the synthesis and investigation of chimeric structures where 6-quinoline and 8-quinoline caging units are integrated in multipolar systems to yield “hybrid” molecular structures for two-photon uncaging. These systems were demonstrated to exhibit strikingly enhanced (up to more than 2 orders…
Three halogen bonded co-crystals between tetraphenylethylene derivatives with peripheral pyridine groups and 1,4- or 1,2-diiodotetrafluorobenzene have been characterized. Two crystalline networks prepared from 3-pyridyl-substituted tetraphenylethylene exhibit remarkably similar topologies, each featuring an open squar…
Zinc sulphide was obtained through hydrothermal decomposition of [Zn(S2CNEt2)] under different experimental conditions such as temperatures and reaction times. Hydrothermal reactions were carried out in a stainless steel autoclave at 160, 180 and 200 °C for 3, 6 and 24 hours. The obtained products were characterized u…
Fabrication of crimped fibers has been caught much attention recently due to remarkable improvement surface-to-volume ratio. The precise mechanism of the fiber crimp is, however, rare and preliminary. This paper finds that pulsation of fibers is the key factor for fiber crimp, and its configuration (wave formation) co…
The rutting of asphalt pavement structures during their exploitation is considered to be one of the main problems in Lithuania, as well as in the entire world. This kind of pavement distress makes a negative impact to the exploitation characteristics of the asphalt pavement, to the residual life of pavement structure,…
Single crystals of CdSiP2 (CSP) with the dimension of 8 mm in diameter and 40 mm in length were successfully grown using vertical Bridgman method. Optical observations showed the presence of macro-defects including flaws and inclusions in the as-grown crystals. The macro-defects can be restrained through controlling t…
The values of the parameters of the equivalent circuit model of the combination wave (surge) generator, which appears in the standard IEC 61000-4-5, are here derived so that open-circuit voltage and short-circuit current exactly meet the standard waveform requirements in terms of peak amplitude, front-time and duratio…
We have studied the relative stabilities of Bingel-Hirsch non-IPR endohedral metallofullerene monoadducts having one, two, or three adjacent pentagon pairs. The most stable addition always leads to an open adduct and never occurs on [5,5] bonds. Our results show that the thermodynamics of the addition is governed by t…
Pyramid-like GaN nanorods have been epitaxially grown on a [001]-oriented sapphire substrate. The as-synthesized GaN nanorods exhibited decent crystal quality and a strong luminescence in UV range.
Copper zinc tin sulfur (CZTS) thin films have been extensively studied in recent years for their advantages of low cost, high absorption coefficient (≥104 cm−1), appropriate band gap (~1.5 eV), and nontoxicity. CZTS thin films are promising materials of solar cells like copper indium gallium selenide (CIGS). In this w…
Protein fusion technology is one of the most commonly used methods to extend the half-life of therapeutic proteins. In this study, in order to prolong the half-life of Granulocyte colony stimulating factor (G-CSF), the domain III of human serum albumin (3DHSA) was genetically fused to the N-terminal of G-CSF. The 3DHS…
Fabrication of multifunctional ultrasound contrast agents (UCAs) has been recently addressed by several research groups. A versatile strategy for the synthesis of UCA precursors in the form of biodegradable vesicles with a biocompatible crosslinked polymer shell is described. Upon ultrasound irradiation, acoustic drop…
In the last few years electrode-organic layer-nanoparticle constructs have attracted considerable research interest for systems where in the absence of the nanoparticles the electrode is passivated. This is because it has been observed that if the organic layer is a good self-assembled monolayer that passivates the el…
This work provides structural evidence for different desulfurization processes in aqueous solutions of [CuL]+ derivatives (HL = pyridine-2-carbaldehyde thiosemicarbazone). Structural resolution has been achieved for the [{CuL(SH)}2] (1), [CuLCl]2[Cu(pic)2] (pic− = picolinato, pyridine-2-carboxilato) (2) and [Cu(HL)(NC…
Zinc doped tin oxide (Zn-doped SnO2) with three dimension (3D) cubic structure has been successfully grown on top of ZnO thin film. In this research, ZnO thin films prepared by rf magnetron sputtering and cubic structure of Zn-doped SnO2 developed by immersion method at low temperature are reported. The effects Zn dop…
Highly electron deficient pyrido[3',2':4,5]furo[2,3-b]pyridine (PFP) was developed as a core structure of a triplet host material and a derivative of PFP, 3-(3-(carbazole-9-yl)phenyl) pyrido[3',2':4,5]furo[2,3-b]pyridine (CzPFP), was synthesized as a bipolar host material. The CzPFP host material showed similar hole a…
Chemical looping combustion (CLC) is a second generation carbon capture process and is discussed as a potential breakthrough technology with respect to CO2 avoidance costs. The potential of CLC has already been successfully demonstrated at scales up to 140 kW power input, using gaseous fuels. The next stage of process…
The enclathration of benzene and toluene by Werner complexes has been described. In the case of toluene, time-lapse PXRD analysis reveals that solid-liquid and solid-vapour reactions proceed according to different pathways. These preliminary results suggest that solid-liquid reactions destroy the host structure, where…
The argon-oxygen-decarburization (AOD) process is a common metallurgical treatment to decarburize high-chromium steel melts using oxygen and inert gas injection through sidewall tuyeres and a toplance. AOD converters are characterized by a fast and efficient decarburization, whereby the oxidation of chromium is reduc…
