Crystal structure prediction (CSP) studies are not limited to being a search for the most thermodynamically stable crystal structure, but play a valuable role in understanding polymorphism, as shown by interdisciplinary studies where the crystal energy landscape has been explored experimentally and computationally. CS…
The importance of dynamics to biomolecular function is becoming increasingly clear. A description of the structure-function relationship must, therefore, include the role of motion, requiring a shift in paradigm from focus on a single static 3D picture to one where a given biomolecule is considered in terms of an ense…
Hydrogel products constitute a group of polymeric materials, the hydrophilic structure of which renders them capable of holding large amounts of water in their three-dimensional networks. Extensive employment of these products in a number of industrial and environmental areas of application is considered to be of prim…
Gradient scaffolds are needed for interface tissue regeneration. In this study, a technique combining electrospinning and electrospraying was developed for preparing poly(L-lactide- co -glycolide) (PLGA) fiber-microsphere scaffolds for loading bioactive substances in gradient amounts. The gradient fiber-microsphere sc…

800x600 CALCULATION OF THE NEED FOR COOLING TOWER ON DESIGN OF STRAND TEST RESEARCH REACTOR CONTROL SYSTEM . Cooling tower on the strand test engineering research reactor control system functioning as a heat transfer medium from the heat exchanger to air. To get the transfer of heat or cooling is maximal then the dete…
The influence of sliding speed on the unlubricated tribological behaviors of silicon nitride–boron nitride (Si3N4-hBN) composites was investigated with two modes in air by a pin-on-disc tribometer. Using the upper disc–on–bottom pin test mode, as the sliding speed increased, the friction coefficient of the sliding pai…
Epoxidised soybean oil (ESBO) is widely used as a plasticiser and stabiliser mainly in food contact materials on the base of polyvinylchloride (PVC), especially in the gaskets of jar lids. PVC gaskets containing 10-37% of ESBO were prepared by the baking of PVC plastisols at various process temperatures (180-240°C) in…
We have developed submicron-sized liposomes modified with a mucoadhesive polymer to enhance peptide drug absorption after oral administration. Liposomal behavior in the gastrointestinal tract is a critical factor for effective peptide drug delivery. The purpose of this study was to prepare quantum dot- (QD-) loaded su…
Abstract A simple thermodynamic system model for the analysis and evaluation of possible SOFC system concepts with regard to reachable electric efficiency is presented. All reforming concepts, various available fuels and anode off‐gas recirculation are included in the model. Furthermore, the model allows the character…
It is shown that the ferroelectric phase transitions in the mixture compounds PbZr1−xTixO3 (PZT), Pb(Mg1/3Nb2/3)1−xTixO3 (PMN-PT), and Pb(Zn1/3Nb2/3)1−xTixO3 (PZN-PT) are described by a twelfth-order expansion of the Landau potential in terms of the phenomenological order parameter. Classical Poincaré transformation i…
Bi3.4La0.6Ti3O12/CoFe2O4 bilayer films were synthesized by chemical solution method and deposited by spin coating on Pt (Pt/TiO2/SiO2/Si) substrate. X-ray diffraction of the bilayer system revealed the composite-like structure. The leakage current is less than 10−7 A at electric field below100 kV/cm, and it shows the…
Novel bis- and tris-fused tetrathiafulvalene (TTF) analogs possessing [5]radialene with quintuple 1,3-dithiol-2-ylidene moieties (2-4) were successfully synthesized. Cyclic voltammetry and differential pulse voltammetry revealed that they exhibited a simultaneous four- or eight-electron transfer process. It is suggest…

Abstract In this study, the performances of single micro‐tubular solid oxide fuel cells based on the NiO–YSZ/YSZ/LSM system with two different current‐collection architectures were compared. In the first case, a straight Ni wire was inserted within the hole of the cell before the electrochemical testing, and in the se…
Electrical rectification in graphene-based three-terminal nanojunctions is simulated using the finite element method. The model is based on diffusive charge carrier transport in a field-effect transistor configuration. The influence of device geometry, temperature, and electric potential disorder on the rectification…
Abstract Silver nanoparticles (AgNPs) were obtained by a redox reaction, using a glucose-containing cyclosiloxane as a reduction agent and stabilizer. Then the AgNPs aqueous solution was used as the reaction medium for the sol-gel process, starting from tetraethylorthosilicate (TEOS) as silica precursor. The nanocompo…
Color images of steady state water vapor condensing on smooth and nanostructured hydrophobic surfaces are presented. Figure 1a shows a snapshot of classical filmwise condensation on hydrophilic copper. A thin liquid film forms on the high surface energy substrate and acts as a conduction barrier for heat transfer. Fig…
In this article, we present a theoretical framework that provides predictable results on band gap modifications due to the addition of dopants into CdSe quantum dots (QDs). A theoretical model is developed that predicts a lowering of the conduction band minimum (CBM) due to hybridization. We then use x-ray absorption…
A recently proposed method to calculate the a parameter of the unit cell of layered double hydroxides from the fraction of trivalent cations is extended to Zn- and Co-based phases. It is shown to be useful as a sanity test for extant and future structure determinations and computer-simulation studies.
