A chloride ion selective thin film sensor is proposed for measuring chloride ion concentration, which is an environmental parameter correlated to corrosion. In this work, electrochemical polymerization of Polypyrrole (PPy) doped with chloride ions was achieved on the top of a carbon nanotube (CNT) thin film as a worki…
Flexibility is an important property of porphyrins, both natural and synthetic. We applied two synchrotron-based techniques, nuclear resonance vibrational spectroscopy and inelastic X-ray scattering, to quantify this property by measuring the bulk modulus of a protein active-site mimic [chloro(octaethylporphyrinato)ir…
X-ray diffraction from protein crystals is routinely measured at cryogenic temperatures, primarily to minimize radiation damage. Protein crystals and the surrounding mother liquor have high water content, which can lead to ice formation when samples are cooled to cryogenic temperatures. Cryoprotectants are added to th…
Of the factors that mainly affect the efficiency of the wing during a special flow regime, the shape of its airfoil cross section is the most significant. Airfoils are generally designed for a specific flight condition and, therefore, are not fully optimized in all flight conditions. It is very desirable to have an ai…
Abstract Three tripodal ligands H3L1–3 containing imidazole rings were synthesized by the reaction of 1,10‐phenanthroline‐5,6‐dione with 1,3,5‐tris[(3‐formylphenoxy)methyl]benzene, 1,3,5‐tris[(3‐formylphenoxy)methyl]‐2,4,6‐trimethylbenzene, and 2,2′,2"‐tris[(3‐formylphenoxy)ethyl]amine, respectively. Trinuclear RuII p…
In this paper we investigate the Jahn–Teller distortion and magnetic property in parent and doped anisotropic triangular compound NaxMnO2. We first determine the Jahn–Teller distortion modes of the MnO6 octahedra by minimizing the potential energy. Then we demonstrate by the cluster self-consistent field method that t…
Shape Memory Alloy (SMA) spring has great potential as a component of compact actuating system. Trade-off between recovery force and deformation range due to phase transformation is possible through the control of spring design parameters such as spring diameter. Deformation behavior of SMA spring is complicated funct…
An appropriate continuum theory to predict the behavior of flexible magnetic or electrically polarized materials undergoing large deformations is explained. The formulation treats the angular momentum as an explicit complementary principle including net-couples from magnetic resp. electric fields. As a consequence non…
The anaerobic cellulolytic rumen bacterium Eubacterium cellulosolvens produces a large array of cellulases and hemicellulases that are responsible for the hydrolysis of plant cell-wall polysaccharides. One of these enzymes, endoglucanase Cel5A, comprises two tandemly repeated novel carbohydrate-binding modules (CBMs)…
Surface electromagnetic waves at the interface of a semi-infinite isotropic medium and a one-dimensional photonic crystal consisting of alternating optically active layers of a planar 3m, 4mm, or 6mm symmetry class are considered. The layers differ only in the sign of the antisymmetric magnetoelectric pseudotensor tha…
Despite the valuable contributions of robotics and high-throughput approaches to protein crystallization, the role of an experienced crystallographer in the evaluation and rationalization of a crystallization process is still crucial to obtaining crystals suitable for X-ray diffraction measurements. In this work, the…

In this report, we grow MnCr2O4 (124) films, and Mn2CrO4 (214) films, for comparison, on MgO and SrTiO3 (STO) substrates by oxygen-plasma-assisted molecular beam epitaxy and also carry out the measurements of the magnetization as a function of temperature (5–200 K) and external field (0–5 T) of these films. The result…
Current strategies in modeling shape memory alloy (SMA) behavior follow either the concept of classical irreversible thermodynamics or the methodology of phenomenological approaches at the micro as well as at the macro space scale. The objective of the present study is to show a new approach in modeling SMA's by using…
A hybrid composite based on the intercalation of methotrexate (MTX) into the layered double hydroxides (LDHs) has been synthesized by the ion exchange technique. The influence of layer charges, altered by the molar ratio of Mg element to Al, on the property of MTX/LDH compounds has been studied. It was found that the…
The gene product of the sas2203 ORF of Staphylococcus aureus MSSA476 encodes a 30 kDa molecular-weight protein with a high sequence resemblance (29% identity) to tetrameric inositol monophosphatase from Thermotoga maritima. The protein was cloned, expressed, purified to homogeneity and crystallized. Crystals appeared…
Oxidization of diamond in the sintering process of diamond/glass composites results in uncontrolled expansion with many irregular pores and low bending strength of the tools. In this paper, Al powder was used as oxygen getter due to its excellent affinity with oxygen. Its oxidization product, Al 2 O 3 , entered into g…
Harvested vibration energy is typically considered as an alternative power source for sensors' networks for health and usage monitoring in civil and mechanical structures. The longevity, and hence the efficacy, of these sensors is severely limited by the levels of generated power. Piezoelectric vibration harvesters ha…
From automobile industry to aerospace, thermoformed composites are more and more in use. Thermoplastics offer a number of attractive applications in commercial use like short production times, tailored solutions, recyclability and lower cost. The thermoforming process allows for producing carbon fiber-reinforced parts…
A synthetic route to prepare fullerene [60] polyvinyl pyridine composites (FPVPC) in supercritical carbon dioxide (scCO2) is presented. The synthetic route involve 2, 2'-azobisisobutyronitrile (AIBN) initiated free radical polymerization of vinyl pyridine (VPY) in presence of fullerene [60] (C60) under various conditi…
