Simulations using classical molecular dynamics are reported on the binding of the protein Ovocleidin-17 to calcite stepped surfaces. vicinal surfaces ({31.8} and {31.16}) are used to obtain acute and obtuse steps. The simulations demonstrate that binding is greater at the obtuse step. A range of analytical methods is…
A Gd complex based on a polyphosphonated pyridyl ligand shows a very high stability in aqueous solution (log K(EuL) = 25.7), a high relaxivity (8.5 mM(-1) s(-1) at 25 °C and 20 MHz) and a marked and selective relaxivity enhancement (37%) in the presence of Mg(2+), opening interesting perspectives for the design of cat…
Programmed biomolecular self-assembly is a powerful method for the construction of designed supramolecular materials. Here, we show that branched ∼8 kDa subunits composed of α-helical coiled-coil protein domains cross-linked at their midpoints by an organic bridging group can form defined supramolecular polymer assemb…
We report a protein-stabilized mechanism to understand the formation of molecular hydrogels from hydrophobic compounds.
The facile synthesis of halogenated multi-walled carbon nanotubes with Cl, Br and I under high pressure and high temperature was reported, and the unique photoluminescence of the halogenated carbon nanotubes was investigated by means of experimental and theoretical approaches. The one-step and facile method to incorpo…
Large area silicon nitride (SiN(x)) nanoporous surfaces are fabricated using poly(ether-ether-ketone) (PEEK) nanorod arrays as a template. The procedure involves manipulation of nanoporous anodic aluminum oxide (AAO) templates in order to form an ordered array of PEEK nanopillars with high temperature resistant charac…
We present the simple procedure of the vapor-phase bromination of multiwall carbon nanotubes (MWNTs) at moderate temperatures. MWNTs with average diameter 9±3 nm were treated with Br2vapors at 250°C to produce Br-functionalized product. Transmission electron microscopy analysis was used to prove low damage of MWNT wal…
Among the large number of applications of montmorillonite and halloysite, low attention has been devoted to the photostabilization effect of these matrices on photounstable agents and no studies have been performed concerning their employment for drug photostability improvement. Herein we report the preparation of nov…
We use computer simulations to study the phase separation behavior of amphiphilic linear gradient copolymer solution under poor solvent conditions. Using the bond fluctuation model and parallel tempering algorithm, we explore the influence of the gradient strength (the largest difference in the instantaneous compositi…
One carbon atom is too many. Two subphthalocyanine-extended TTF electron donor-acceptor conjugates were synthesized and characterized. Their photophysical properties prompt the remarkable impact that one extra carbon between the two constitutents exerts on photoinduced processes, that is, charge recombination dynamics…
Some new and obtained earlier experimental data on the elastic precursor decay and rise times of plastic shock waves in several metals and alloys at normal and elevated temperatures are discussed. The time range available for measurements has been expanded to picoseconds that allows approaching ultimate shear and tens…
We report the syntheses and characterizations of the first polyoxothiometalate complexes isolated from the reaction of the oxothiocationic [Mo(V)(2)O(2)S(2)](2+) precursor and bisphosphonate ligands H(2)O(3)PCR(OH)PO(3)H(2) (R = C(4)H(5)N(2), zoledronic acid; R = C(3)H(6)NH(2), alendronic acid). [(Mo(2)O(2)S(2)(H(2)O)…
In this study, polymeric nanocapsules of PCL containing the herbicide atrazine were prepared. In order to optimize the preparation conditions, a 23 factorial design was performed using different formulations of nanocapsules, which investigated the influence of three variables at two levels. The factors varied were the…
A novel technology has been developed for the synthesis of thioglycolic acid (TGA)-capped CdTe quantum dots (QDs) in aqueous medium. The reaction was carried out in air atmosphere with one-pot by using Na 2 TeO 3 to replace Te or Al 2 Te 3 . The mechanism for the formation of CdTe QDs is elucidated. The influences of…
We investigated the thermoelectric properties of titanium sulphene, namely, few-layered TiS(2) nanosheets, by using density functional theory and the Boltzmann transport equations. The Seebeck coefficient of titanium sulphene was found to increase if the thickness fell below 14 triple layers (~8 nm) and for the monola…
Light controllable release of antinflammatory zinc ions by a smart multifunctional material composed of spiropyrans and single walled carbon nanotubes (SWNTs) is demonstrated. The exploitation of a number of complementary characterization techniques allows the investigation of both composition and performance of the m…
Two ferritic stainless steel (FSS) sheets were produced to display different recrystallization textures. The in-plane variation of the Lankford parameter R(α) was calculated from the sheet textures and compared to the R-values determined experimentally. The textures of the FSS sheets were further decomposed into a num…
A second polymorphic form of a 1 : 2 : 3 pamoate : DABCO : water salt has been obtained by liquid-assisted grinding, and it is shown that interconversion between this salt and a salt with 1 : 1 : 2 stoichiometry is facile via liquid-assisted grinding with additional amounts of pamoic acid (to generate the 1 : 1 : 2 sa…
Controlled reductive assembly of capped Keggin anions [PMo(12)O(40)(ML(m))(n)](3-) has been achieved by reduction of [PMo(12)O(40)](3-) with sodium-mercury amalgam in the presence of metal halides, as exemplified by the rational syntheses of mono-capped [PMo(12)O(40){Co(MeCN)(2)}](3-) and bi-capped [PMo(12)O(40)(VO)(2…
The filling of hierarchical branched porous anodic alumina (PAA) templates with magnetic and metallic nanowires using pulsed electrodeposition is here addressed in detail. We show that the electrodeposition potential (and current) reveals clear anomalies when each generation of branched pores created by steady-state o…
