We present nanophotonic light harvesting crystalline silicon c Si thin films on glass exhibiting ten fold transversely quasicrystalline lattice geometry on 6 x 8 mm2 area. The c Si architectures with a nearest neighbor distance of 650 nm are fabricated by nanoimprinting the desired quasicrystalline geometry into sol g…
The main aim of this study was to design novel pentablock (PB) (PLA–PCL–PEG–PCL–PLA) polymer to prepare nanoparticles (NP) in order to achieve sustain delivery of pazopanib with minimal burst effect for the treatment of ocular neovascularization. Another purpose was to evaluate the effect of pazopanib loaded NP to byp…
β-nuclear magnetic resonance (NMR) spectroscopy is highly sensitive compared to conventional NMR spectroscopy, and may be applied for several elements across the periodic table. β-NMR has previously been successfully applied in the fields of nuclear and solid-state physics. In this work, β-NMR is applied, for the firs…
Processing solvents and conditions have unique importance in the performance of bulk heterojunction organic solar cells. In the present work, we have investigated the role of a primary solvent and solvent additive in the device performance of two benzobisthiazole (BBTz)-based push–pull type polymers. In an inverted ce…
Discrete self-assembly of two Re(I) squares was achieved by a simple and efficient strategy where the complexes, [Re(4-pytpy-κ(2)N)(CO)3Br] and [Re(4-pytpy-κ(3)N)(CO)2Br], act as their own ligands. The photophysical and electrochemical properties of the assemblies and their precursors are described along with solid-st…
The geometric and electronic structure of the MIL-47(V) metal-organic framework (MOF) is investigated by using ab initio density functional theory (DFT) calculations. Special focus is placed on the relation between the spin configuration and the properties of the MOF. The ground state is found to be antiferromagnetic,…
The growth of ordered arrays of InGaN/GaN nanocolumnar light emitting diodes by molecular beam epitaxy, emitting in the blue (441 nm), green (502 nm), and yellow (568 nm) spectral range is reported. The device active region, consisting of a nanocolumnar InGaN section of nominally constant composition and 250 to 500 nm…
Bismuth oxide was synthesized via simple, rapid and energy efficient solution combustion synthesis (SCS) by employing sucrose as a fuel. This SCS-Bi2O3 was characterized by analytical techniques such as PXRD, SEM, EDX, UV-Visible and BET surface area measurement. Using the prepared SCS-Bi2O3, several classes of hetero…
Molybdenum carbide is a promising material for replacing the hydrogenation catalysts used in industry. It has been synthesized using different sources of molybdenum oxides and carbon, such as molybdenum heptamolybdate, molybdenum oxides, glucose, alkanes, and toluene. Nonstoichiometric material is produced, normally f…
Abstract Das Aufkommen von ionischen Flüssigkeiten (ionic liquids, ILs) als umweltfreundliche und vielversprechende Reaktionsmedien eröffnete neue Möglichkeiten im Bereich der elektrochemischen Energiespeicherung. Über ihre Verwendung als Elektrolytbestandteile in Batterien und Superkondensatoren hinaus zeigen ILs ein…
C10H18N2Na2O10 (ethylenediaminetetra-acetic acid disodium salt) inhibition and adsorption mechanism on the corrosion of steel-reinforcement corrosion in concrete immersed in corrosive environments were investigated in this paper. For this, seven different concentrations ranging from 0% to 0.667% C10H18N2Na2O10 per wei…
It has been shown in vitro that melanocyte proliferation and function in palmoplantar skin is regulated by mesenchymal factors derived from fibroblasts. In this study, we investigated in vivo the influence of mesenchymal-epithelial interactions in human tissue-engineered skin substitutes reconstructed from palmar- and…
We have synthesized four new uranyl complexes. Their photoluminescence was characterized and their photocatalytic properties were studied in detail.
We herein describe a coordination polymer system built upon the reactions of a W/Cu/S cluster precursor [Et4N][Tp*WS3(CuBr)3] (1, Tp* = hydridotris(3,5-dimethylpyrazol-1-yl)borate) with three equivalents of CuCN through solvent modulation. Four coordination polymers, namely, [Tp*WS3Cu3(μ3-DMF)(CN)3Cu(Py)] (2), [Tp*WS3…
Highly ordered hierarchical TiO2 nanotube (HTNT) arrays are obtained with a facile and low-cost approach, which can be applied in flexible fiber-type dye-sensitized solar cells (DSSCs). To achieve the HTNT arrays, smooth TiO2 nanotube (STNT) arrays are fabricated by a two-step anodization process followed by hydrother…
The synthesis of thiazole(Tz)-based regioisomer materials using selective direct arylation to avoid any protection steps has been developed. A series of trimers in which the Tz groups sandwich either an electron-rich or an electron-deficient unit, with a regioselective orientation of the respective Tz unit, has theref…
Dual-modal imaging contrast agents with unique X-ray computed tomography (CT) and optical imaging capabilities have attracted much attention in recent years. Herein, the new silica hybrid nanocomposites containing Au nanoparticles and FITC dyes (FITC–Au@SiO2) were investigated as this kind of contrast agent. TEM chara…
In situ sum frequency generation vibrational spectroscopy (SFG) was used to monitor the reductive desorption of decanethiol (DT) and octadecanethiol (ODT) self-assembled monolayers (SAMs) grown on evaporated gold on silica. At negative potentials, the alkyl chains of both monolayers became disordered as monitored by t…
We present the structural and spectroscopic characterization of six uranyl tetrachloride compounds along with a quantified analysis showing the influence of both the crystallographic phase and the lattice solvent upon the vibrational properties of the uranyl moiety. From the uranyl symmetric and asymmetric stretching…
