We investigate the transmission of electrons between conducting nanoribbon leads oriented at multiples of $60\ifmmode^\circ\else\textdegree\fi{}$ with respect to one another, connected either directly or through graphene polygons. A mode-matching analysis suggests that the transmission at low energies is sensitive to…
A systematic and detailed investigation of the structure of As(x)Te(100-x) glasses (20<or=x<or=60) has been undertaken using a combination of structure-probing techniques including high energy x-ray diffraction, neutron diffraction, and x-ray absorption fine structure measurements at the As and Te K edges. The experim…
Two hydroxy-functional hyperbranched aliphatic polyesters based on 2,2-dimethylolpropionic acid (bis-MPA) and a partially aromatic conventional polyester have been studied as thermoset resins for solvent-borne thermally cured polyester cross-linked with melamine coatings for precoated sheet metal, i.e., coil coatings.…
Results are presented for the absolute bremsstrahlung yields at a backward angle of 135\ifmmode^\circ\else\textdegree\fi{} from $53\phantom{\rule{0.3em}{0ex}}\mathrm{keV}$ electrons on gold targets of thickness ranging from $66\phantom{\rule{0.3em}{0ex}}\text{to}\phantom{\rule{0.3em}{0ex}}28\phantom{\rule{0.2em}{0ex}}…
The complex [Dy(BA) 3 bipy] 2 (BA = benzoate; bipy = 2,2′-bipyridine) was obtained and characterized by elemental analysis, molar conductance, infrared spectra (IR), ultraviolet spectra (UV), single-crystal X-ray diffraction, thermogravimetry, and differential thermogravimetry (TG-DTG) techniques. The crystal is monoc…
A procedure to estimate the statistical uncertainties associated with free energies computed from thermodynamic integration using fitted data is described. The method involves generating synthetic data sets from the actual simulation data and performing an analysis of the resulting distribution of free energy values.…
We show, both heuristically and numerically, that three-dimensional periodic Lorentz gases-clouds of particles scattering off crystalline arrays of hard spheres-often exhibit normal diffusion, even when there are gaps through which particles can travel without ever colliding-i.e., when the system has an infinite horiz…
Air-stable single-source molecular precursor is applied for controlled size and morphology synthesis of one-dimensional and quasi-one-dimensional CdSe nanostructures. Two different growth approaches are compared to control the growth of nanostructures. When combined with well-defined Au colloidal catalysts, the use of…
Three new magnetic resonance imaging probes that target glutamine transporters have been synthesized. They consist of a Gd-DOTA-monoamide moiety (DOTA=1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) linked through a six carbon atom chain to a vector represented by a glutamine residue bound through alpha-carb…
Mn-doped CdS nanocrystals were synthesized via the modified reverse-micelle method and then a CdS/SiO 2 core–shell structure was prepared under hydrolysis of tetraethyl orthosilicate (TEOS) without any coupling agent. Basing on the method, four typical samples with different Mn 2+ ions concentrations were fabricated.…
Rapid expansion techniques (of supercritical solution (RESS) and into a liquid solvent (RESOLV)) with supercritical carbon dioxide are used to form chitin microstructures. The effect of the pre-expansion conditions, temperature (40−60 °C), pressure (104−208 bar), chitin concentration (1−6 mg/mL), and nozzle diameter (…

Nuclear quadrupole resonance (NQR) is a solid-state radio frequency (RF) spectroscopic technique that allows for the detection of many narcotics and highly explosive substances. Unfortunately, the practical use of NQR is often restricted by the presence of strong RF interference (RFI). In this letter, extending our re…
A large functionally graded single crystal has been synthesized by the Czochralski method. The resulting rod has a continuous composition range of Ba 8 Ga 16 (Si x Ge 1- x ) 30 going from x = 0.20(1) to 0.41(1). The exact composition was determined along the pulling direction by energy-dispersive X-ray spectroscopy (E…
A sandwich-type polyoxometalate, [Cu(4)(GeW(9)O(34))(2)](12-) (1a), in which two B-alpha-[GeW(9)O(34)](12-) ligands sandwich a rhomblike Cu(4)(8+) tetragon through alpha-Kappaeggin linkage, is first isolated as a [n-BuNH(3)](+) salt, [n-BuNH(3)](12)[Cu(4)(GeW(9)O(34))(2)].14H(2)O (1). A Cu(4)O(14) cluster for the rhom…
The aim of this publication is to present a general strategy to engineer more efficient photoluminescent dendritic molecules based on polyhedral oligomeric silsesquioxane (POSS) cores. A series of chromophores were grafted on POSS cores to form dendritic molecules for which steric hindrance was used as a trigger to tu…
Measurements of dc conductivity and ac magnetic susceptibility under pressure to 12 GPa as well as of the crystal structure under pressure were made on antiferromagnetic ${\text{LaMnO}}_{3}$ and ferromagnetic ${\text{LaMn}}_{0.5}{\text{Ga}}_{0.5}{\text{O}}_{3}$ crystals. Collapse of magnetic ordering in both crystals…
The ability to construct size- and shape-controllable architectures is essential for the exploration of nanoparticle-structured properties, and it is a good strategy of employing metal nanoparticles embedded in a polymer matrix in order to prepare new materials with particular properties. Herein, we found that adenosi…
Investigations on shape and chemical composition of one-dimensional magnetite nanostructures grown by a catalyst-assisted vapor phase procedure are reported. Intrinsic crystal chemistry (preferred growth of most stable surfaces) could be modulated by seeding the magnetite growth through Au nanoclusters, which led to e…
A near-infrared (NIR) fluorescence sensing strategy for glucose and xanthine has been developed based on the interaction between CdTe quantum dots (QDs) and biocatalytic generated Au nanoparticles. The fluorescence of CdTe QDs is modulated by changing concentration of AuCl4- and Au nanoparticles during the growth proc…
