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 <italic>Escherichia coli</italic> showed inactivation kinetics for PHMB capsules consistent with <italic>in vitro</italic> 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…
Adding multi wall carbon nanotubes to Mg <sub>2</sub> Si <sub>0.877</sub> Ge <sub>0.1</sub> Bi <sub>0.023</sub> led to an increased power factor <italic>via</italic> energy filtering as well as a lowered thermal conductivity <italic>via</italic> increased phonon scattering, and thus an enhanced thermoelectric performa…
In the fight against antibiotic resistance, gold nanoparticles (AuNP) with antibiotics grafted on their surfaces have been found to be potent agents. Ampicillin-conjugated AuNPs have been thus reported to overcome highly ampicillin-resistant bacteria. However, the structure at the atomic scale of these hybrid systems…
Highly monodispersed Ag embedded SiO <sub>2</sub> nanostructured thin films have been synthesized and their sensitivity towards SERS investigated.
In H-aggregation, BOXD-6 adopts a linear conformation and forms a one-dimensional layered structure; in J-aggregation, it adopts a Z-shaped conformation and forms a more ordered two-dimensional layered structure.
Zn-doped Zintl compounds of Sr <sub>5</sub> In <sub>2</sub> Sb <sub>6</sub> show enhanced thermoelectric efficiencies, reaching <italic>zT</italic> of ∼0.4 at 750 K for Sr <sub>5</sub> In <sub>1.9</sub> Zn <sub>0.1</sub> Sb <sub>6</sub> .
Metal dodecaborates M2/nB12H12 are among the dehydrogenation intermediates of metal borohydrides M(BH4)n with a high hydrogen density of approximately 10 mass%, the latter is a potential hydrogen storage material. There is therefore a great need to synthesize anhydrous M2/nB12H12 in order to investigate the thermal de…
Using the nonequilibrium Green’s function method combined with spin-polarized DFT, we investigate the spin-resolved electronic transport properties of devices made of poly-(terphenylene-butadiynylene) (PTB) between zigzag graphene nanoribbon (ZGNR) electrodes.
Supramolecular heterometallic gels with synergistic properties were prepared for the first time using ligand with Co(2+) and Ni(2+), and their macroscopic self-healing has been achieved by improving the unfavorable viscoelasticity of each monometallic gel.
ZnO 3D hierarchical structures with different morphologies can be selectively synthesized at room temperature by using potassium hydroxide and citric acid as an etchant and capping agent, respectively.
