The authors show that superhydrophilic TiO2 can be obtained without irradiation of the surface with ultraviolet (UV) light and concomitant excitation of electron-hole pairs. The authors demonstrate that the treatment of TiO2 surfaces with reactive oxygen species generated by air plasma removes the surface organic cont…
CONTEXT: Triosephosphate isomerase (TIM) is a ubiquitous enzyme that has been targeted for the discovery of small molecular weight compounds with potential use against Trypanosoma cruzi, the causative agent of Chagas disease. We have identified a new selective inhibitor chemotype of TIM from T. cruzi (TcTIM), 1,2,4-th…
Synthetic macromolecular diblocks sorting into mutivesicular bodies (MVBs) and their fluorophore encapsulation pathways were reported. Renewable resource based diblocks having hydrophobic units and flexible hydrophilic polyethylene glycols (PEG) were custom designed for the above purpose. Single crystal structure was…
A selective liquid/solid displacement reaction has been used, for the first time, to convert non‐oxide ceramic solid solutions into composites comprised of intragranular metal nanoparticles embedded within non‐oxide ceramic microcrystals. The reaction of ( Zr x W 1− x ) C microparticles with a Zr – Cu liquid at 1300°C…
Ordered phases on curved substrates experience a complex interplay of ordering and intrinsic curvature, commonly producing frustration and singularities. This is an especially important issue in crystals as ever-smaller scale materials are grown on real surfaces; eventually, surface imperfections are on the same scale…
The pressure dependence of bulk properties for the group 12 chalcogenides MX (M = Zn, Cd, Hg; X = S, Se, Te) from density functional theory are presented. Energy-volume and corresponding enthalpy-pressure relationships are determined to obtain the transition paths and properties of various high-pressure phases. The in…
Two new coordination polymers, [Zn(p-CH3C6H5SO3)2(bpp)2] n (1) and [Cu2(SCN)2(NO3)2(bpp)4] n (2) (bpp = 1,3-bis(4-pyridyl)propane), have been synthesized and characterized. Single crystal X-ray diffraction analysis reveals that 1 and 2 exhibit 2-D layer networks composed of alternate left-handed and right-handed bpp-c…
We examine the complexation behavior of polyelectrolyte stars on oppositely charged colloidal particles with similar sizes by means of computer simulations employing the molecular dynamics approach. In particular the overcharging phenomenon is considered and its dependence on the charge and functionality of the stars.…
Auf der Oberfläche: Eine Bibliothek von organisch-anorganischen Palladium-Nanokristallen wurde in einem Mikrofluidiksystem unter überkritischen Bedingungen synthetisiert. Die Nanokatalysatoren zeigten je nach Art der Liganden mittlere bis exzellente Aktivitäten in CAr-B- und CAr-CAr-Kupplungen.
4-Alkylaryl layers were electrodeposited on Au surface via formation in situ of diazonium cations and the subsequent electroreduction in solution of 4-alkylanilines (4-CH 3 (CH 2 ) n C 6 H 4 NH 2, n = 5–13). The electrodeposited layers were characterized with X-ray photoelectron spectra (XPS), an atomic force microsco…
The purpose of this investigation is to determine whether a large oligomeric protein, inorganic pyrophosphatase (IPPase) from Thermococcus thioreducens with quaternary structural complexity, would have distinguishable dynamic characteristics compared to those of the small simple monomeric model protein, lysozyme. In t…
The temperature (T)-pressure (P) phase diagrams are reported for the tetragonal layered compounds CeRu(2)Al(2)B, CeRu(2)Ga(2)B, and CeRu(2)Ga(2)C, studied by magnetization, specific heat and electrical resistivity. These systems exhibit localized 4f magnetic ordering with ferromagnetic ground states at T(C) = 12.8 K,…
A suite of novel high-resolution spectroscopic imaging diagnostics has facilitated the identification and localization of molybdenum impurities as the main species during the formation and lifetime of m = 1 impurity-induced snake-modes on Alcator C-Mod. Such measurements made it possible to infer, for the first time,…
We present a review of the recent progresses in solution processing graphene thin films and highlight some of the uses of graphene and graphene thin films in the construction of organic solar cells. We demonstrate a simple phenomenological model to describe the relationship between sheet conductivity and transmittance…
TiO 2 was loaded on Cr-MCM-4s8 and Cr-KIT-6 mesoporous silica matrixes (TiO 2 /Cr-MCM-48 and TiO 2 /Cr-KIT-6) synthesized in alkaline and acidic conditions to achieve visible-light driven photocatalytic activity. The influences of pore ordering, Cr species, and content of mesoporous matrixes to the photocatalytic acti…
A novel [¹⁸F]-labeled cholesteryl ether lipid probe was prepared by synthesis of the corresponding mesylate, which was [¹⁸F]-fluorinated by a [¹⁸F]KF, Kryptofix-222, K₂CO₃ procedure. Fluorination was done for 10 minutes at 165°C and took place with conversion between 3 and 17%, depending on conditions. Radiolabelling…
Two mononuclear copper(II) complexes, [Cu(C(15)H(16)NO(2))(2)] (1) and [Cu(C(6)H(9)N(2)O(4))(2)·3H(2)O] (2·3H(2)O), were synthesised and structurally characterised by single-crystal X-ray analysis. The copper(II) atom adopts a square-planar environment in complex 1, while the geometry in 2·3H(2)O could be described as…
The second osmotic virial coefficient is in principle obtained from the second-order term in the expansion of the osmotic pressure Π or solute activity z(2) in powers of the solute density ρ(2) at fixed solvent activity z(1) and temperature T. It is remarked that the second-order terms in the analogous expansions at f…
It is well known that the Poisson-Nernst-Planck (PNP) theory and the classical Gouy-Chapman theory are inconsistent at a high applied voltage. For solving this problem, we propose an ion-conserving Poisson-Boltzmann theory, which shows remarkable agreement with the numerical PNP solutions, even at a high applied volta…
A general problem in tissue engineering is the poor and insufficient blood supply to guarantee tissue cell survival as well as physiological tissue function. To address this limitation, we have developed an in vitro vascularization model in which a decellularized porcine small bowl segment, representing a capillary ne…
