Michelia alba leaves extract was first reported as a general highly-efficient inhibitor for acid corrosion of different steels.
Variational calculus is employed to determine the folding behaviour of a single graphene sheet.
Six Ln III –furan-biradical tri-spin complexes have been synthesized, they exhibit interesting magnetic properties. Dy III complex shows frequency-dependent ac magnetic susceptibilities, which suggests the presence of slow magnetic relaxation.
Co-based bimetallic nanocrystals with one-dimensional (1D) branches were synthesized by the heterogeneous nucleation of Co atoms onto prenucleated seeds, such as Pd or Cu, through a facile wet-chemical route. The peripheral branches (rod-like) of the Co-Pd and Co-Cu nanocrystals were outspread along the (001) directio…
“High quality sub-10 nm graphene nanoribbons by on-chip PS- b -PDMS block copolymer lithography”, SEM image of sub-10 nm graphene nanoribbons fabricated using a brushless lamellar PS- b -PDMS (5k–5.5k) block copolymer and its Raman spectra.
Silicon carbide nano-fibers with high aspect ratio improve the EMI shielding effectiveness of epoxy at low concentration.
Rationally designed reduced graphene oxide/Mn 3 O 4 (GM) was achieved and GM showed long-stability capacitance after 5000 cycles at 1 A g −1 .
The La-doped SmBaFe 2 O 5+δ series of materials were investigated systematically to determine whether they may serve as effective cathodes.
Oxides with the tetragonal tungsten bronze (TTB) structure are well-known ferroelectrics that show a large flexibility both with respect to chemical composition and cation ordering. Two of the simplest compounds in this family are lead metaniobate (PbNb2O6 or PN) and strontium barium niobate (SrxBa1-xNb2O6 or SBN). Wh…
Surface functionalization by glutaraldehyde effectively enhanced hydrophilicity of polyaniline nanofibers (PNFs) rendering them with improved biocompatibility as revealed by MTT assay and membrane stability test.
Currently, the design and construction of an intelligent stimuli-responsive gel system is still a significant challenge. We present here a new gel system from which the formation of heat-set gels, conventional gels and irreversible heat-set gels can be achieved in aromatic solvents. This gel system is based on two-com…
Silica capsules with PHMB were produced through a water/oil emulsion. Antimicrobial studies against a recombinant luminescent strain of Escherichia coli showed inactivation kinetics for PHMB capsules consistent with in vitro studies at pH 7.4.
Pd-doped Beta exhibits excellent catalytic performance for selective synthesis of isobutane from synthesis gas while Pd-free Beta could not.
The reflection loss of PVP/MWNTs and PEI/MWNTs hybrids in paraffin; the mass fractions of hybrids in the absorbents are different.
Data derived from a voltammetric and spectroscopic study of the V(V/IV) couple associated with the initial reduction of the Wells-Dawson-type mono vanadium-substituted polyoxometalates, 1- and 4-[S2V(V)W17O62](5-) in CH3CN as a function of CF3SO3H acid concentration have been obtained. (51)V NMR (V(V) component) and E…
Chitin – a naturally occurring biopolymer – was employed for the first time as a binder for carbon electrodes and studied in electrochemical capacitors.
X-ray diffraction methods in general provide a representation of the average structure, thus allowing only limited chemical selectivity. As recently shown [D. Chernyshov, et al., Acta Crystallogr., Sect. A: Found. Crystallogr., 2011, 67, 327], some structural information on a subset of atoms can be obtained using the…
We report the coexistence of stress-bearing percolation with arrested phase separation in a colloidal system of thermoresponsive nanoemulsions spanning a broad range of volume fractions (0.10 ≤ ϕ ≤ 0.33) and temperatures (22 °C ≤ T ≤ 65 °C). Here, gelation is driven by short-range interdroplet polymer bridging at elev…
GO coating on Ag nanoparticles enhances SERS signals and improves the long term stability of Ag.
The objective of present study was to develop an optimized polymeric nanoparticle system for the antiretroviral drug tenofovir. A modified nanoprecipitation method was used to prepare Eudragit RS PO nanoparticles of the drug. The effect of amount of polymer, surfactant concentration, and sonication time on particle si…
