We conducted simultaneous high-pressure $(P)$ and high-temperature $(T)$ unit-cell volume $(V)$ measurements of ${\text{H}}_{2}\text{O}$ ice VII in an externally heated diamond anvil cell using in situ synchrotron x-ray diffraction technique with an angle-dispersive system. Isothermal unit-cell volume of ice VII was c…

Abstract In this article, we report on the viscoelastic and thermal properties of agarose–polyacrylamide (PAAm) interpenetrating polymer hydrogels (IPHs) and semi‐IPHs as a function of agarose concentration and PAAm crosslinking degree. The results demonstrated that the agarose is able to gel in the presence of crossl…

Protein quality control pathways rely upon ATP-dependent proteases, such as Escherichia coli ClpAP, to perform maintenance roles in the cytoplasm of the cell. ATP-dependent proteases remove misfolded and partially synthesized proteins. This action is particularly important in situations where an unregulated accumulati…

Heat shock protein 90 (Hsp90) is a prime target for antitumor therapies. The information obtained by molecular dynamics (MD) simulations is combined with NMR data to provide a cross-validated atomic resolution model of the complementary interactions of heat shock protein 90 with a peptidic (shepherdin) and a non-pepti…

PEG/CD polyrotaxane was prepared under seven conditions with different temperature and presence/absence of different types of end-capping molecules (adamantanamine or diphenylethylamine). The polyrotaxane was synthesized even without the addition of end-capping molecules, via undesirable esterification between termina…

Highly aligned single crystal SnO 2 (101) nanowires were epitaxially grown on TiO 2 (101) substrates by thermal evaporation via Au-catalyzed vapor−liquid−solid (VLS) growth. The orientation relationship and interface structure between the nanowires and the substrate were determined by X-ray pole figure and high resolu…

Noncovalent interactions between protonated porphyrin and fullerenes (C₆₀ and C₇₀) were studied with five different meso-substituted porphyrins in the gas phase. The protonated porphyrin-fullerene complexes were generated by electrospray ionization of the porphyrin-fullerene mixture in 3:1 dichloromethane/methanol con…

Studies aimed at elucidating the unknown Mg2+ binding site in protein farnesyltransferase (FTase) are reported. FTase catalyzes the transfer of a farnesyl group to a conserved cysteine residue (Cys1p) on a target protein, an important step for proteins in the signal transduction pathways (e.g., Ras). Mg2+ ions acceler…

In the past decade, significant progress has been made in protein structure prediction. However, refining models to a level of resolution that is comparable with experimental results and can be used in studies like enzymatic activity still remains a major challenge. We have previously demonstrated that our modular pro…

Density functional theory is used to evaluate activity and stability properties of shell-anchor-core structures. The structures consist of a Pt surface monolayer and a composite core having an anchor bilayer where C atoms in the interstitial sites lock 3d metals in their locations, thus avoiding their surface segregat…

Solid acid catalysts based on zirconia materials were investigated for the first time as catalysts for regioselective organic synthesis under environmentally benign and mild conditions. The novel TiO 2 −ZrO 2 mixed oxide catalyst led to two distinct products by the formation of an N−C bond (β-amino alcohols) and a C−C…

The crown ether 21-crown-7 was found to be effective as a crystal habit modifier of zeolite L. The function of the template was to facilitate the bridging of cancrinite columns on the {101̅0} face and hence increase the crystal diameter while hindering growth in the long axis of the crystal. The rational selection of…

Homogeneous core–shell structured cuprous oxide (Cu2O) is fabricated through a facile reduction reaction at room temperature (20–25 °C). Ostwald ripening processes are proposed to explain the growth mechanism of the homogeneous Cu2O core–shell structure. The electrochemical impedance spectrum (EIS), cyclic voltammetry…
