Abstract Three metal–dicyanamide (dca) coordination polymers combined with isonicotinamide (4‐nic) terminal co‐ligand, namely, [Mn(dca)2(4‐nic)2]n (1), [Co(dca)2(4‐nic)2]n·2nCH3OH (2) and [Mn(dca)2(4‐nic)2]n (3) were synthesized at room temperature. X‐ray single crystal diffraction reveals that complexes 1 and 2 have…
The NMR structure of the protein NP_247299.1 in solution at 313 K has been determined and is compared with the X-ray crystal structure, which was also solved in the Joint Center for Structural Genomics (JCSG) at 100 K and at 1.7 Å resolution. Both structures were obtained using the current largely automated crystallog…
The pressure and energy behavior of the Gaussian core model (GCM) fluid as a function of strain-rate are obtained from nonequilibrium molecular dynamics simulations for a wide range of thermodynamic state points. An analytical dependence of pressure on strain-rate is observed which is in agreement with a Taylor series…
In the title complex, [Ni(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)]·4H(2)O, the Ni(II) ion is coordinated in a slightly distorted octa-hedral environment formed by two bis-chelating H(2)pimda (H(3)pimda is 2-propyl-1H-4,5-dicarb-oxy-lic acid) ligands and two coordinated water mol-ecules. In the crystal structure, a three-dimens…
Cardiovascular disease is one of the leading causes of death in the United States, and new treatments need to be developed in order to provide novel therapies. Tissue engineering aims to develop biologic substitutes that restore tissue function. The purpose of the current study was to construct cell-based pumps, which…
Thermal reliability of nickel (Ni) and copper (Cu) gate AlGaN/GaN high electron mobility transistors (HEMTs) is investigated. Though the current-voltage characteristics of as-deposited Cu gate AlGaN/GaN HEMTs is superior to those of Ni gate AlGaN/GaN HEMTs, severe degradation was observed after aging at 220°C. This in…
At any pressure sensitive quantum critical point (QCP) the thermal expansion is more singular than the specific heat leading to a divergence of the Grüneisen parameter. For a magnetic field sensitive QCP, the complementary property is the magnetic Grüneisen ratio which equals the magnetocaloric effect. Here we use bot…
Abstract Four three‐dimensional heterometallic coordination polymers, [Ln2Cu4I3(IN)7(H2O)]n (1, 2) and [LnCu3.5I3(IN)3.5(H2O)3]n·nH2O (3, 4) [HIN = isonicotinic acid, Ln = Nd (1), Gd (2), La (3), Eu (4)] were hydrothermally synthesized by using lanthanide oxides, isonicotinic acid, copper chloride, and potassium iodid…
The heteroscorpionate N(2)S(2) donor ligand bis(3,5-tertbutylpyrazol-1-yl)dithioacetate (L) was prepared as a Li(+) trinuclear complex, which co-crystallizes with tetrahydrofuran (THF) solvent molecules: [Li(L)](3) x (2.25)THF. When [Li(L)](3) was reacted with AgBF(4) or [Cu(CH(3)CN)(4)]BF(4), the oligonuclear species…
Based on the polarization curves and electrochemical impedance spectroscopy (EIS) in the case of four commercial dental alloys (Wirolloy, Heraenium, NicromalSoft and VeraSoft) maintained in 0.1M NaCl solution, it was established the type and the intensity of the corrosion process by means of the corrosion currents val…
Playing a dual role as a catalyst that destabilizes Fe nanoparticles to form soluble precursors in situ and as a catalytic center for nanorod growth allows Pd nanoparticles to transform Fe nanoparticles and a P source into Fe2P nanorods (see scheme). The diameter and length of the Fe2P nanorods can be fine-tuned by me…
Abstract In this paper, we describe the results from an experimental campaign, focused on vertical upward flame spread over a charring material. First, for validation purposes of simulation tools, we report on cone calorimeter results for square (9.8cm×9.8cm), 1.65 cm thick, medium density fibre samples, mounted horiz…
An exhaustive analysis of all H-bond networks for finite elements of ice nanotubes formed by up to 32 water molecules (3,660,732 configurations in total) is performed. The results constitute a unique database and demonstrate the H-bond network formation and changes with the growth of the ice nanotube. The statistical…

A number of experimental and theoretical studies have suggested that the surface of water−ice is liquidlike. Ions in a liquidlike layer should be hydrated, whereas they are included in a salt crystal if the surface of ice is solidlike. Thus, the local structure of an ion can be a useful probe for the state of the ice…
The processes of etching and diffusion of atomic oxygen on the reconstructed Si(100)-2 × 1 surface are investigated using an embedded cluster QM/MM (Quantum Mechanics/Molecular Mechanics) method, called SIMOMM (Surface Integrated Molecular Orbital Molecular Mechanics). Hopping of an oxygen atom along the silicon dimer…
Abstract BACKGROUND: The present work aims to gain further insight on the use of Fusarium solani pisi cutinase from a Saccharomyces cerevisiae strain for the synthesis of short chain ethyl esters, a group of important fruit flavor compounds, in a non‐conventional environment. Synthesis is promoted by cutinase in organ…
Lithium−manganese ferrite LiFeMnO 4 was prepared using two different methods: a conventional ceramic high-temperature solid-state reaction technique (Cer) and thermal decomposition of metal nitrate salts (NTD). The characterization of the compounds was carried out by SEM/EDX, XRD, XPS, Fe K- and Mn K-edge XANES, and M…
Leukotriene A4 hydrolase (LTA4H) is a key enzyme in the inflammatory process of mammals. It is an epoxide hydrolase and an aminopeptidase of the M1 family of the MA clan of Zn-metallopeptidases. We have solved the crystal structure of LTA4H in complex with N-[3(R)-[(hydroxyamino)carbonyl]-2-benzyl-1-oxopropyl]-L-alani…
Abstract The curing behavior of the dicyanate ester of bisphenol‐A (DCBA) modified with poly(hydroxy ether of bisphenol‐A) (phenoxy) is studied by differential scanning calorimetry in dynamic and isothermal tests at temperatures between 120 and 240°C. The addition of phenoxy to DCBA produces an increase in the reactio…
