A series of sodium borosilicate glasses were synthesized with KR eO 4 or Re 2 O 7 , to 10,000 ppm (1 mass%) target Re, to assess effects of large concentrations of rhenium on glass structure and fto estimate solubility of 99 Tc , a radioactive component in low active waste nuclear glasses. Rhenium was used as a surrog…
Lisinopril is extensively used as an ethical anti-hypertensive drug in its dihydrate crystalline phase, where this phase undergoes dehydration to the metastable monohydrate and anhydrous phases upon being heated. The mechanistic aspects of this two-step dehydration process are successfully established from their cryst…
This paper reports the results of micro- to nanostructural and geochemical analyses of calcitic skeletons from extant deep-sea stalked crinoids. Fine-scale (SEM, FESEM, AFM) observations show that the crinoid skeleton is composed of carbonate nanograins, about 20-100 nm in diameter, which are partly separated by what…
Enzymes containing flavin cofactors are predominantly involved in redox reactions in numerous cellular processes where the protein environment modulates the chemical reactivity of the flavin to either transfer one or two electrons. Some flavoenzymes catalyze reactions with no net redox change. In these reactions, the…
We report the ferroelectric properties of single-crystalline BiFeO3 nanowires using piezoresponse force microscopy (PFM). The nanowires, synthesized by a hydrothermal approach, have a rhombohedral perovskite structure and a preferential growth of the (211) crystallographic plane perpendicular to the wire axis, as reve…
We report the high-resolution and broadband light-scattering spectroscopy of a single crystal of a prototypical relaxor ferroelectric, $\mathrm{Pb}({\mathrm{Mg}}_{1/3}{\mathrm{Nb}}_{2/3}){\mathrm{O}}_{3}$. A self-similar broad central peak, whose intensity is expressed as $I(\ensuremath{\omega})\ensuremath{\propto}{\e…
Stoichiometric reactions of YCl 3 (THF) 3 with potassium 2-((arylimino)methyl)quinolin-8-olates or 2-(1-(arylimino)ethyl)quinolin-8-olates in THF solution gave the mononuclear LYCl 2 (DMSO) 2 complexes 1 – 5 in the presence of DMSO and a representative dinuclear complex 6 in the absence of DMSO. All yttrium complexes…
The long‐term stability of direct carbon fuel cells, based on solid oxide fuel cells with molten Sb and Sb–Bi anodes, was examined for operation with activated charcoal, rice starch, and bio‐oil fuels at 973 K. With intermittent stirring of the fuel–metal anode interface, the anode performance was stable, and reasonab…
The effect of ferroelectric poling on the adsorption characteristics of water at lithium niobate surfaces is investigated by ab initio calculations. Thereby we model the adsorption of H${}_{2}$O monomers, small water clusters, and water thin films on the LiNbO${}_{3}$(0001) surface. The adsorption configuration and en…
A novel strategy for affinity-based surface modification of the conducting polymer, polypyrrole, (PPy), has been developed. A 12-amino acid peptide (THRTSTLDYFVI, hereafter denoted T59) was previously identified via the phage display technique. This peptide noncovalently binds to the chlorine-doped conducting polymer…
Transport and Kelvin probe force microscopy measurements were simultaneously conducted on epitaxial VO2 thin films. The sample's work function abruptly dropped from 4.88 eV to 4.70 eV during heating from 333 K to 353 K, suggesting a significant change in its electronic band structure spanning the metal insulator trans…
The (1− x ) NaNbO 3 –( x ) NaTaO 3 solid solution was investigated for x ≤ 0.4 in terms of new high‐temperature and high‐permittivity dielectric system that is suitable for base metal inner electrode capacitor applications. The addition of Ta significantly enhanced the resistivity of the dielectric, resulting in super…
Recent advances in micro- and nanotechnology have provided a variety of particles with highly controlled shapes, sizes, chemical composition, and interesting properties. In this work, a novel kind of heparin-functionalized polyurethane microsphere (Hep-PU MS) was synthesized by a single-step phase separation method. T…
A series of novel terbium tetracyanoplatinate compounds all incorporating tridentate 2,2':6'2″-terpyridine (terpy) or 4'-chloro-2,2':6'2″-terpyridine (terpy-Cl) were synthesized and used to investigate the phenomenon of dual-donor sensitization of Tb(3+). Judicious choice of the Tb(3+) salt and reaction conditions res…
Abstract This work identifies the influence of strain rate, temperature, plastic strain, and microstructure on the strain rate sensitivity of automotive sheet steel grades in crash conditions. The strain rate sensitivity m has been determined by means of dynamic tensile tests in the strain rate range 10 −3 –200 s −1 a…
The photooxidation of 9-anthraldehyde can be catalyzed by colloidal Au nanoparticles (AuNP) or diamond-supported Au nanoparticles (AuNCD) by using LED excitation at 530 nm. Visible irradiation of the plasmon band of AuNP in an acetonitrile solution of 9-anthraldehyde saturated with oxygen or air results in formation o…
A series of calcium complexes supported by NNO-tridentate ketiminate ligands have been synthesized and characterized. X-ray structural studies indicate that these complexes bear a mononuclear feature with hexa-coordinated calcium centers bonding to two ketiminate ligands. Polymerization of L-lactide catalyzed by these…
Advanced scaffold materials are required for liver tissue engineering, to improve primary hepatocyte activity and hepatic function in vitro. The nanotopography of the scaffold material plays an important role in the regulation of cell growth and function. Therefore, in the current study, we developed a novel scaffold…
In this study, a precipitation method was used to synthesise ZnO nanoparticles using suitable precursors. An efficient surface modification method was proposed in order to reduce the agglomeration among synthesised small sized ZnO nanoparticles using 2-aminothiophenol as a capping agent. This article briefly investiga…
