Abstract Durch die Auslegung von Extraktionskolonnen basierend auf Experimenten im Labormaßstab und Simulationen lassen sich Zeit und Kosten sparen, da die heute üblichen, teuren Technikumsexperimente entfallen. Das Verhalten einzelner Tropfen bzw. Tropfenschwärme wird im Labormaßstab untersucht. Systemspezifische Par…
The effect of temperature during solvent annealing on the microdomain orientation of block copolymer ultrathin films was investigated using symmetric polystyrene- block -poly(methyl methacrylate) diblock copolymers. When acetone solvent annealing was performed at low temperatures, 2 °C, 38% of samples exhibited a patt…
Abstract Crystallization of strontium carbonate is performed in aqueous solution using Gum Acacia (GA) as crystal growth modifier. A novel study of hierarchical assembly, specifically interacting inorganic and natural component without introduction of other additives was studied. SrCO 3 structures exhibiting the morph…
The overexpression of BI-1 induces an acidic extracellular pH due to alterations of mitochondrial function, leading to cancer metastasis through anaerobic glucose metabolism. In this study, ion transporters such as sodium hydrogen exchangers (NHE) and monoamine carboxylate transporters (MCTs) were studied in BI-1-over…
Hydrogen is a promising energy source for the future economy due to its environmental friendliness. One of the important obstacles for the utilization of hydrogen as a fuel source for applications such as fuel cells is the storage of hydrogen. Hydrogen has high gravimetric energy content but low volumetric energy dens…
It is no accident that the start of the 21st century has seen significant growth in the field of nanotechnology across all the sciences. The nanoscale is the realm of the molecule, where physics, chemistry and biology meet, and where the potential for engineering control of structures containing tens to thousands of a…
Lithium-doped ZnO films were deposited by radio frequency magnetron sputtering on Corning 1737 glass substrates. The Li content in the films varied from 0 to 10 at. %, as determined by wavelength-dispersive X-ray analysis and inductively coupled plasma mass spectrometry. The effect of Li content on the microstructure…
The solubility data of azadirachtin in supercritical carbon dioxide were measured at several temperatures (308.15, 313.15, 318.15, 323.15, 328.15, and 333.15 K) and at pressure between (10 and 26) MPa. The measurement of solubility data was conducted in static mode. The experimental results were correlated by Chrastil…
Abstract Synthesis of linked ZnO micro rods by microwave radiation and its characterization is presented in this report. In this simple microwave assisted solution phase route zinc nitrate and hexamethylenetetramine has been used as the starting materials for the synthesis of linked ZnO rods. Linked ZnO rods with vari…
In this research, the cell morphology and physico-mechanical properties of HDPE/EVA/Rice hull hybrid foamed composites were investigated. For this aim, composites were prepared via melt mixing and then foamed using a compression molding method. Mechanical properties such as tensile strength, tensile and flexural modul…
We have performed an angle-resolved photoemission spectroscopy study of the iron-based superconductor (SC) ${\mathrm{Sr}}_{2}{\mathrm{VFeAsO}}_{3}$. While V $3d$ orbitals are found to be in a Mott-insulating state and show an incoherent peak at $~1 \mathrm{eV}$ below the Fermi level, the dispersive Fe $3d$ bands form…
In this study, we report the synthesis and characterization of nanohydroxyapatite (nHAp) in gelatin-starch matrix via biomimetic method. Characterization of the samples was performed using X-ray diffraction (XRD) and Fourier Transform infrared spectroscopy (FT-IR). The Size and morphology of the nHAp samples were dete…
Resistance and magnetic torque measurements at low temperatures under high magnetic fields have been performed for a magnetic organic conductor (Me-3,5-DIP)[Ni(dmit)${}_{2}$]${}_{2}$ to investigate the electronic state. This conductor contains two types of Ni(dmit)${}_{2}$]${}_{2}$ anion layers, layers I and II. Shubn…
The influence of the degree of saturation (DOS) of a gas in a solution on the intensity of multibubble sonoluminescence (MBSL) excited by ultrasound with a frequency of 261 kHz is investigated at various ultrasonic powers and with different concentrations of ethanol, which is added as a volatile solute. At relatively…
Light-driven intramolecular electron transfer (ET) and energy transfer (EnT) processes in two rotaxanes, the first containing two free base porphyrins and C(60) fullerene moieties incorporated around a Cu(I)bisphenanthroline core ((H(2)P)(2)-Cu(I)(phen)(2)-C(60)) and a second lacking the fullerene moiety ((H(2)P)(2)-C…
We derive equations for the quasiclassical Green's functions $\mathrm{g\ifmmode \check{}\else \v{}\fi{}}$ within a simple model of a two-band superconductor with a spin density wave (SDW). The elements of the matrix $\mathrm{g\ifmmode \check{}\else \v{}\fi{}}$ are the retarded, advanced, and Keldysh functions, each of…
Abstract VO 2 exists in four phases, among which, the M/R phase VO 2 is well known for its reversible metal‐semiconductor phase transition at about 68 °C, and VO 2 (B) is a promising candidate cathode material to be applied in aqueous lithium‐ion battery owing to its proper electrode potential and layered structure. I…
The Pb(2)Fe(2)O(5) compound with a layered intergrowth structure has been prepared by a solid-state reaction at 700 °C. The incommensurate compound crystallizes in a tetragonal system with a = 3.9037(2) Å, c = 3.9996(4) Å, and q = 0.1186(4)c*, or when treated as a commensurate approximant, a = 3.9047(2) Å, c = 36.000(…
In this work, the solubility of carbamazepine–succinic acid cocrystals in ethanol and acetone were measured at (298.15 and 308.15) K at atmospheric pressure. The solubility product ( K sp ) which reflects the strength of cocrystal solid-state interactions of carbamazepine (CBZ) and succinic acid (SUC) relative to inte…
One of effective ways to reduce pollution from cigarette butts is introduced by recycling the cigarette butts. Inhibitor from recycled cigarette butts shows good inhibition properties, but we do not know whether CuCl can help to improve the inhibition efficiency. So, in this study, the impact of CuCl on recycled cigar…
