The electrochemical behavior of colloidal solutions of graphene oxide (GO) is described here in detail. The GO reduction is shown to exhibit near-reversible electron transfer on Pt electrodes, based on E1/2 and ΔEp values. The observed peak current is found to depend linearly on the concentration of the GO and the squ…
When facing the challenges of critical dimension measurement of complicated nanostructures, such as of the three dimension integrated circuit, characterization of the focal depth of microscopes is important. In this Letter, we developed a method for characterizing the focal depth of a scanning helium ion microscope (H…
Understanding the mechanism of prenyltransferases is important to the design of engineered proteins capable of synthesizing derivatives of naturally occurring therapeutic agents. CloQ is a Mg(2+)-independent aromatic prenyltransferase (APTase) that transfers a dimethylallyl group to 4-hydroxyphenylpyruvate in the bios…
Abstract For better observation of the microstructure of cast aluminium alloys under an optical microscope, the contrast obtained for the different micro constituents was enhanced by making use of a copper phthalocyanine based colorant. The proposed method allows distinguishing structural details which would remain hi…
Phase behaviors induced by solvent annealing in poly(methyl methacrylate) (PMMA) and poly(styrene-ran-acrylonitrile) (SAN) blend ultrathin films have been investigated by atomic force microscopy and grazing incidence small-angle X-ray scattering. Our results indicate that both the phase separation within the blend and…
The structural and (13)C/(1)H NMR parameters of the four crystal forms (1α, 1·H2O, 1β, and 1γ) of the solid wheel-and-axle (WAA) metal-organic compound [(p-cymene)Ru(κN-INA)Cl2] have been studied by means of periodic DFT calculations. The quality of the results obtained strongly depends on a correct description of lon…
Two new Phen-Co(II) complexes bridged by a hydroxyl isophthalate ligand, {[Co(dimphen)(HIA)]·H2O}n (1) and {[Co(phen)(HIA)]·H2O}n (2) (dimphen = 2,9-dimethyl-1,10-phenanthroline, phen = 1,10-phenanthroline, HIA = 5-hydroxyisophthalic acid), have been synthesized by carefully tuning the basicity of the reaction medium.…
Examples of blends of carbazole- and bis(oxadiazole)benzene-based side-chain polymers have recently been reported to be efficient host materials for phosphorescent emitters in organic light-emitting diodes. Here, the properties and performance of a physical blend of polynorbornene homopolymers with triscarbazole and b…
In this study, the mechanical response of a single yarn pull-out from single layers of Kevlar® and Twaron® fabric under out-of-plane loading at dynamic rates was experimentally investigated, as ballistic applications typically occur at higher velocities and out-of-plane directions compared to previous literature. In o…
The fatigue response of electrodeposited Ni-W on low carbon steel substrate was studied. The considered Ni-W coatings are a promising substitute for toxic hard chromium coatings which, according to EU directives (2000/53/WE, 2011/37/UE), must be eliminated. Specimens of pure substrate and those covered by coating were…
We describe our technique for reconstructing the free right atrial wall and superior vena cava using CorMatrix (CorMatrix Alpharetta, GA, USA) extracellular matrix following resection of a large leiomyosarcoma. doi: 10.1111/jocs.12398 (J Card Surg 2015;30:351–354)
The dielectric properties of CaMgSi 2 O 6 glass-ceramics were investigated at microwave frequencies as a function of Cr 2 O 3 –Fe 2 O 3 –TiO 2 (CFT) content and heat-treatment method. The specimens with 0.5 wt % CFT heat-treated at 900 °C for 3 h showed the maximum degree of crystallization and a high quality factor (…
Abstract A heteroleptic ruthenium sensitizer (DV56) bearing a terpyridine ligand with an appended phenylanthracene moiety was synthesized and extensively characterized. The physicochemical properties of the light‐harvesting antenna were studied in solution and on sensitized TiO2 thin film electrodes using a variety of…
In this work, a new classical density functional theory is developed for group-contribution equations of state (EOS). Details of implementation are demonstrated for the recently-developed SAFT-γ WCA EOS and selective applications are studied for confined fluids and vapor-liquid interfaces. The acronym WCA (Weeks-Chand…
This study reports on the smoldering propensity of commercially available barrier fabrics in a small-scale mock-up configuration. Most barrier fabrics are smolder resistant when tested alone over a standard flexible polyurethane foam. However, when covered with a smolder-prone cover fabric, most barrier fabrics failed…
The stability, electronic, and optical properties of (6,5) single-walled carbon nanotubes (CNTs) functionalized with free-base tetraphenylporphyrin (TPP) molecules through π-stacking interactions are studied by ab-initio calculations. The stability and optical response of the CNT-TPP compounds for increasing CNT-surfa…
Inorganic oxides are recognized as attractive materials for developing anodes for wastewater treatment, potentially offering a cost effective solution for electro-oxidation. A key parameter in measuring the effectiveness of different anode materials is the oxygen over potential. In this paper, we study the role of Zn…
In the current study, human keratinocyte cell line was used as in vitro cell culture model to elucidate the effects of the fatty acid chain length of acylglutamate (amino acid-based surfactant) namely, sodium cocoyl glutamate, sodium lauroyl glutamate, and sodium myristoyl glutamate on their cytotoxicity and the ultra…
We investigate the spectral density of shot noise and current for the system of a quantum dot coupled to Majorana bound states (MBS) employing the nonequilibrium Green's function. The Majorana bound states at the end of the wire strongly affect the shot noise. There are two types of coupling in the system: dot-MBS and…
Three new branched peptides, namely, H-Gly-Dap(H-Gly)-Gly-NH2 (3G), H-His-Dap(H-His)-Gly-NH2 (2HG), and H-Gly-Dap(H-Gly)-His-NH2 (2GH), where Dap stands for the 2,3-diaminopropionic acid residue, were synthesized by solid phase procedures. Because of the junction at Dap these peptides have three available pending arms…
