Abstract A new type of layered zirconium glycine‐N,N‐dimethylphosphonate (ZGDMP), with enlarged interlayer d‐spacing and a polar carboxylate group (COO–), was prepared and characterized by Fourier transform infrared (FTIR) spectroscopy, X‐ray diffraction (XRD), and scanning electron microscopy (SEM). ZGDMP was interc…
We present a general method for calculating the genus distributions of those infinite families of graphs that are obtained by iteratively amalgamating copies of some base graphs along their root-edges . We presume that the partitioned genus distributions of these base graphs are known and that their root-edges have 2-…
The chiral [Cu(cyd) 4 ] 6− anion acts as a multiarmed complex-ligand toward auxiliary copper(II) centers leading to the first example of cytidinate-bridged three-dimensional (3D) coordination polymer of formula [Cu 6 (H 2 O) 7 (ClO 4 ) 3 Cu(cyd) 4 ](ClO 4 ) 3 ( 1 ). Single crystal X-ray analysis of 1 shows a unique 3D…
This article discusses calibration issues for shallow depth nanoindentation experiments with Berkovich tips with respect to the accurate measurement of the diamond area function (DAF). For this purpose, two different calibration procedures are compared: (i) the direct measurement of the DAF through atomic force micros…
The use of nanoscale x-ray probes overcomes several key limitations in the study of materials up to multimegabar (> 200) pressures, namely, the spatial resolution of measurements of multiple samples, stress gradients, and crystal domains in micron to submicron size samples in diamond-anvil cells. Mixtures of Fe, Pt, a…
2-[5′- N -(3-triethoxysilyl)propylurea-2′-hydroxyphenyl]-benzothiazole (HBTNH2) was covalently bonded to the inner surface of amorphous silica nanoparticles and unmodified and Al-doped mesoporous structured silicate, MCM-41 and (Al)MCM-41, respectively. The photodynamics of these materials was investigated using stead…
Active packaging of fruits and vegetables uses films that absorb molecules from or contribute molecules to the produce. The pilot application developed in this paper has resulted in the deposition of film to apples. A prospective application relates to replacing hot wax that is expensive and that lowers the textural q…
In Corynebacterium glutamicum, the unphosphorylated 15-kDa OdhI protein inhibits the activity of the 2-oxoglutarate dehydrogenase complex (ODHc) by binding to OdhA, which in corynebacteria and mycobacteria is a large fusion protein with two major domains exhibiting structural features of E1o and E2 proteins. Using cop…
Multiscale methods are quickly becoming a new paradigm in many branches of science and engineering. This includes computational engineering, and to underline the growing importance of the subject the Editors of the International Journal for Numerical Methods in Engineering have decided to publish a Special Issue on Mu…
For the numerical simulation of non-linear piezoelectric material behavior, we use a constitutive relation that is based on a decomposition of the physical quantities dielectric displacement and mechanical strain into a reversible and an irreversible part. Therein, we set the irreversible part of the dielectric displa…
A thorough understanding of the growth and surface properties of calcium−phosphate nanocrystals is essential for uncovering the mechanism by which their nanostructure interacts with other molecules. Herein, we reported a facile wet-chemical approach using cetyltrimethylammonium bromide (CTAB) for the oriented growth o…
We previously reported a novel drug delivery system, drug-linker-Phe-Phe-Arg-methylketone (FFR-mk)-factor VIIa (fVIIa). The method utilizes tissue factor (TF), which is aberrantly and abundantly expressed on many cancer cells. The advantage of this delivery system is its ability to furnish a potent anticancer drug spe…
Sequential crystallization of succinate buffer components in the frozen solution has been studied by differential scanning calorimetry and X-ray diffractometry (both laboratory and synchrotron sources). The consequential pH shifts were monitored using a low-temperature electrode. When a solution buffered to pH < pK(a)…
Nanoscale ferromagnetic inclusions of YFeO 3 have been incorporated into pulsed laser deposited YBa 2 Cu 3 O 7 − δ (YBCO) thin films. The poisoning of the YBCO through the addition of the magnetic material is minor, with 1 mol% doping resulting in an unsuppressed superconducting transition temperature of 90 K. The cri…
We applied hot pressing to in situ powder-in-tube-processed (PIT-processed) MgB 2 tapes. We enhanced the superconducting properties by adding nanometer-sized SiC powder and ethyltoluene (C 9 H 12 ) to the mixed powder. Hot pressing was performed at 100 MPa and 630 °C in an Ar gas atmosphere for 2–10 h. Hot pressing re…
Air-annealing Pt (15 nm)/Ti (5 nm) gate Si-metal–oxide–semiconductor field-effect transistors (Si-MOSFETs) at 400 °C for 2 h revives and enhances the hydrogen sensing activity of nearly all the inert sensor characteristics of the Pt (15 nm)/Ti (5 nm) gate Si-MOSFETs. The sensing amplitudes are changed from 0.0–0.16 V…
The treatment of wastewater containing methyl orange was investigated experimentally using a three-dimensional electrode reactor coupling ultrasonics and the effect of ultrasonics on the degradation was studied. The effects of cell voltage, original concentration of methyl orange, pH value and the concentration of ele…
This paper reports the design and fabrication of high-aspect-ratio needlelike silicon structures that can have complex geometry. The structures are hundreds of micrometers tall with submicrometer-sharp protrusions, and they are fabricated using a series of passivated and unpassivated deep reactive-ion etching (DRIE) s…
The anisotropy of the critical current density (Jc) and its influence on measurement of irreversibility field (Birr) has been investigated for high quality, in-situ MgB2 strands. Comparison of transport and magnetization measurements has revealed the onset of a regime where large differences exist between transport an…
Due to its simple construction and excellent mechanical/thermal stress withstanding capability, induction motor with solid-rotor structure is widely used in many high-speed, high pressure application fields. In this paper, a novel solid-rotor induction motor with skewed slits in both radial and axial directions is pre…
