Six metal-organic frameworks, namely, [Cd(μ(2)-HDMPhIDC)(Py)](n) (H(3)DMPhIDC = 2-(3,4-dimethylphenyl)-1H-imidazole-4,5-dicarboxylic acid, Py = pyridine) (1), [Sr(μ(2)-HDMPhIDC)(H(2)O)](n) (2), {[M1(3)(μ(3)-DMPhIDC)(2)(H(2)O)(6)]·2H(2)O}(n) (M1 = Zn (3), or Mn (4)), [M2(μ(2)-HDMPhIDC)(H(2)O)(2)](n) (M2 = Mg (5), or Ca…
Nitrogen/sulfur co-doped anatase TiO2 nanocrystals with a high specific surface area and a high percentage of {001} facets were synthesized by a solvent-thermal process followed by the calcination with thiourea at an optimum heat treatment temperature. Under current experimental conditions, the optimum heat treatment…
Lipid asymmetry, the difference in inner and outer leaflet lipid composition, is an important feature of biomembranes. By utilizing our recently developed MβCD-catalyzed exchange method, the effect of lipid acyl chain structure upon the ability to form asymmetric membranes was investigated. Using this approach, SM was…
The formation mechanism and crystal growth of TiO 2 in high-temperature high-pressure fluids were studied using HCl or H 2 SO 4 as additives. In situ synchrotron radiation powder X-ray diffraction reveals that phase-pure rutile TiO 2 nanoparticles can be formed using HCl as additive, whereas phase-pure anatase TiO 2 i…
Arbitrary spatial distributions of the electric field of light are formed through the interference of individual wavenumber mode fields with appropriate amplitudes and phases, while the maximum wavenumber in the far field is limited by the wavelength of light. In contrast, localized surface plasmons (LSPs) possess the…
Novel, high "turn-on" Hg(2+) and O(2)(-) fluorescence behaviour (∼25-fold) with probes bearing [S(thi)N(py)] and [S(thi)N(py)N(py)] binding receptors, joined by oxidizable sulphides, may involve S-bound transient ROS species; such optical O(2)(-) behaviour operates moderately in neuroblastoma.
Many materials properties are conditioned by the relative arrangement of metal ions in the solid state. Supramolecular architectures such as helicates may be designed with controlled metal to metal spacing in their midst. However, shorter distances and more extensive electronic communication may be achieved between in…
BACKGROUND: Purine nucleotides exhibit various functions in cellular metabolism. Besides serving as building blocks for nucleic acid synthesis, they participate in signaling pathways and energy metabolism. Further, IMP and GMP represent industrially relevant biotechnological products used as flavor enhancing additives…
Silicon substrates have been a fascinating topic of fundamental and applied research for well over 50 years. They have attracted even more attention over the last couple of decades with advances in chemical functionalization that made oxide-free silicon surfaces a reality. Fundamentally new electronic properties and c…
A Blatter radical is oxidized to benzotriazin-7(H)-one which after amination and subsequent acyl- and aroylation gives N-(benzotriazin-6-yl)carboxamides that undergo ring closure with P(2)S(5) to afford the corresponding thiazolo[5',4':4,5]benzo[1,2-e][1,2,4]triazin-4-yls. These highly delocalized radicals are air sta…
Abstract Two common methods for recording absolute photoluminescence quantum yields using integrating spheres are discussed. These methods are developed from a theoretical standpoint, with a discussion of the assumptions made in each and their principle differences, and practical comparisons between the two are made u…
Abstract As CrO x catalysts supported on the SBA‐15 support (Cr/Si) are highly active, they represent potentially promising catalysts for the oxidative dehydrogenation of propane with CO 2 (ODHP). However, reduction of the active sites (Cr 3+ ) during the reaction is known to lead to severe deactivation. The findings…
Optical trapping techniques have been used to investigate fundamental biological processes ranging from the identification of the processive mechanisms of kinesin and myosin to understanding the mechanics of DNA. To date, these investigations have relied almost exclusively on the use of isotropic probes based on collo…
In recent years, 1-butyl-3-methylimidazolium carboxylates ionic liquids (ILs) have been reported to be powerful solvents for the dissolution of cellulose and chitosan. However, very few studies have been conducted to investigate their basic physicochemical properties such as viscosity and conductivity. In this work, w…
Two electron-deficient truxenone derivatives are designed and synthesised for organic photovoltaic applications. The promise of this class of compounds as acceptor materials is illustrated by the fabrication of efficient bilayer solar cells with a subphthalocyanine (SubPc) donor, clearly outperforming reference cells…
For the first time an external magnetic field has been used for the spatial control of a single amino functionalized mixed component metal–organic framework doped with cobalt nanoparticles. The potential applications as an active material for miniaturized devices (e.g. microchannels and microfluidic circuits) are illu…
Aluminum alloy (Al/3.25Cu/8.5Si) composites reinforced with fly ash particles of three different size ranges (53–75, 75–103, and 103–150 μm) in 3, 6, 9, and 12 weight percentages were fabricated using a stir-casting technique. Pin-on-disc wear tests were conducted with 20, 30, and 40 N loads and sliding speeds of 2, 3…
A heated SiC microtubular reactor has been used to decompose acetaldehyde and its isotopomers (CH(3)CDO, CD(3)CHO, and CD(3)CDO). The pyrolysis experiments are carried out by passing a dilute mixture of acetaldehyde (roughly 0.1%-1%) entrained in a stream of a buffer gas (either He or Ar) through a heated SiC reactor…
A pleated filter bag is often used to treat exhaust gas in many industrial applications, due to its fairly high dust collection efficiency and relatively low pressure drop. This work deals with the optimum pleating geometries of a pleated filter made with a newly developed PTFE/glass composite filter. It was found tha…
The products from slow pyrolysis of birch hardwood are promising to be used for various purposes, in addition to conventional charcoal. To evaluate their utilization, knowledge about their polycyclic aromatic hydrocarbons (PAHs) is needed. The content and distribution of the PAHs in the different products were determi…
