We present a tensorial elastic network model (TNM) to describe the equilibrium fluctuations of proteins near their native fold structure. The model combines the anisotropic network model (ANM), bond bending elasticity, and backbone twist elasticity, and can predict both the isotropic fluctuations, similar to the Gauss…
Glutathione is a tripeptide capable of diminishing active oxygen species in living cells. The photocatalytic decomposition of glutathione and related amino acids in TiO(2) suspension was investigated with (1)H NMR spectroscopy. The results suggest that both glutathione in reduced and oxidative forms is adsorbed on the…
Monolayers of iron oxide nanoparticles of two different sizes, 9.6 nm and 16.5 nm, were fabricated through electrophoretic deposition. The arrangements of nanoparticles within the films were analyzed using the technique of Voronoi tessellations. These analyses indicated that the films possessed equivalent degrees of o…
OBJECTIVE: To evaluate the degree of conversion (DC), flexural strength (FS) and Knoop microhardness (KHN) of direct and indirect composite resins polymerized with different curing systems. MATERIALS AND METHODS: Specimens of direct (Z250, 3M/Espe) and indirect (Sinfony, 3M/Espe) restorative materials were made and po…
Chemical grouting in underground coal mines is related closely to the interaction between grouting materials and coal. In the present work, a novel adhesive with high properties and low cost, waterglass/polyurethane, has been developed for coal bonding, based on a room-temperature-curing process. To obtain a direct an…
We apply the second Born approximation and the BBK methods to study triple-differential cross sections for the ionization of valence orbitals of a thymine molecule by electrons and positrons. Calculations have been performed for a coplanar geometry at an incident energy of 250 eV and an ejected-electron energy of 20 e…
Abstract We report on the effects of monolayer (ML) thick skin-like octadecanethiol (ODT, CH3[CH2]17SH) on type-II InAs/GaSb MWIR photodetectors. Circumventing the ageing effects of conventional sulfur compounds, we use ODT, a self-assembling, long molecular chain headed with a sulfur atom. Photodiodes coated with and…
Abstract We studied a mixture of C12E5 microemulsion with an end-capped hydrophobically modified polymer (C12–PEO–C12). The end-capped polymer adsorbed on the core of the microemulsion, changed the bending properties of the interface and connected two nearby droplets. The core size and width of the structure factor of…
The changes in structural ordering, packing entropy, free energy, and film morphologies in the initial nucleation processes of pentacene (Pn), 6, 13-bis(t-butylethynyl) pentacene (t-Bu Pn), and 6, 13-bis(triisopropylsilylethynyl) pentacene (TIPS Pn) on the SiO(2) substrate were investigated, by using the molecular dyn…
Knowledge about the (inter)dependence of permeation kinetic parameters on the stoichiometry of H 2 -selective alloys is still rudimentary, although uncovering the underlying systematic correlations will greatly facilitate current efforts into the design of novel high-performance H 2 separation membranes. Permeation me…
First-principles calculations have been performed to study the electronic and magnetic properties of metal phthalocyanine molecules (MPc, M = Mn, Fe, Cu) on an Fe(100) surface. All of the three MPc molecules prefer their central atom on the top site and orientation with the M–N1 bond along the ⟨110⟩ direction. Similar…
Alles wird verstaut: Biphenyl-3,4′,5-tricarboxylat reagiert mit Cd(NO3)2 in Gegenwart von meso-Tetra(N-methyl-4-pyridyl)porphintetratosylat zu dem mikroporösen Metall-organischen Material (MOM) porph@MOM-11, das kationische Porphyrine und Lösungsmittel in abwechselnden offenen Kanälen einlagert. Porph@MOM-11 verfügt ü…
We consider crystal and magnetic chiral structures for MnSi and isostructural metal silicides, where a complete set of structural and magnetic measurements allows us to define both magnetic and structural chiral configurations. We show that magnetic symmetry inherits chirality from the crystal structure. We derive, wi…
Sealed structure of plant biomass resists assault on cellulose from enzymatic deconstruction. In this study, pretreatments of triploid poplar were conducted with 0.5 wt % H 2 SO 4 at various temperatures (100–200 °C) to loosen the intricate structure. The effect of temperature on cellulose structure and enzymatic dige…
CeB${}_{6}$ is a cubic heavy-fermion compound with a ${\ensuremath{\Gamma}}_{8}$ ground quartet for which an ESR signal was observed. All other Ce or Yb compounds displaying an ESR signal have strong magnetic anisotropy and ferromagnetic correlations among the spins. The role of the ferromagnetic correlations is to na…
RuO(2) films were deposited on SiO(2) (300 nm)/N++Si substrates using radio frequency magnetron sputtering at room temperature. As-deposited RuO(2) films were annealed at different temperatures (100, 300, and 500 °C) and ambients (Ar, O(2) and vacuum), and the resulting effects on the electrical and physical propertie…
Biomass represents an abundant and relatively low cost carbon resource that can be utilized to produce platform chemicals such as levulinic acid. Novel oligomeric flame retardants, the poly(MDP-PDCP-MA)s (PMPMs), were designed and synthesized using diphenolic acid as one of the raw materials, which is derived from lev…
Chemical trends within the periodic table are frequently used as guides for predicting reactivity, structure, and electronic properties of the elements. While these trends have been rigorously investigated for the transition metals, the understanding of trends within the actinide series is elementary in comparison. He…
With installation of the ITER-like wall in JET a major diagnostic upgrade to measure the neutral gas pressure and composition in the sub-divertor region has been completed, to characterise retention and outgassing of the new metallic first wall. The upgrade includes two new magnetically shielded systems consisting of…
New applications of carbon-based materials have been continuously developed in recent years. Carbon nanofibers (CNFs) with silane coatings were added into high density polyethylene (HDPE) to improve the tribological properties of the nanocomposite material. The nanocomposites were fabricated with various weight percen…
