Sn NPs with well-defined sizes in the range 20–100 nm have been synthesized using a chemical reduction route of metal acetylacetonate by a dimethylamine–borane Lewis complex.
Integrative and comparative analyses of biomaterials systems offer the potential to reveal conserved elements that are essential for mechanical function. The approach also affords the opportunity to identify variation in designs at multiple length scales, enabling the delineation of a range of parameters for creating…
Using methods which are applied for estimating strength and toughness of composites reduces rate of trial-and-error in their design. One of the mechanisms for strengthening and increasing toughness of composites is application of reinforcement pull-out mechanism. Interface strength of reinforcement with matrix and eff…
We have studied the interaction of H2 with Pt-Sn nanoalloys supported on Sn-Ce mixed oxide films of different composition by means of synchrotron radiation photoelectron spectroscopy and resonant photoemission spectroscopy. The model catalysts are prepared in a three step procedure that involves (i) the preparation of…
Deposition of Pd–Fe nanoparticles onto carbon spheres with controllable diameters and catalytic activity for CO oxidation.
Double-walled carbon nanotube (DWNT)-CdSe heterostructures with the individual nanoscale building blocks linked together by 4-aminothiophenol (4-ATP) have been successfully synthesized using two different and complementary routes, i.e. covalent attachment and non-covalent π-π stacking. Specifically, using a number of…
Tin dioxide (SnO2) and graphene are versatile materials that are vitally important for creating new functional and smart materials. A facile, simple and efficient ultrasonic-assisted hydrothermal synthesis approach has been developed to prepare graphene-SnO2 nanocomposites (GSNCs), including three samples with graphen…
Research in solar energy conversion and the associated photoactive materials has attracted continuous interest. Due to its proper electronic band structure, high quantum efficiency, and photonic and chemical innerness, TiO 2 has been demonstrated as a versatile oxide semiconductor capable of efficiently utilizing sunl…
The reduction of graphene oxide by Zn can also result in power-output for a Zn/GO primary cell.
Abstract Porphysomes are an emerging class of photonic nanoparticles formed from the self-assembly of porphyrin-lipid conjugates. They retain the multifunctional properties of their porphyrin building-blocks but also have unique properties emerging from the nanostructure itself. Porphysomes are able to act in a number…
An intestine-like nanoporous carbon was fabricated and used for size-selective separation of cytochrome c.
Dear pss readers, As the previous year approached its end, news on three excellent prize winnings and nominations of pss authors and editors reached us: Gerhard Abstreiter of TU Munich will receive the Stern–Gerlach Medal 2014, the highest prize of the German Physical Society for experimental physics, honoring his wor…
The alloying of Pt with Au did not alter the dehydrogenation of methanol on the Pt sites but affected the scission of the C–O bond of methanol.
Nb and F co-doped anatase TiO2 layers were deposited by low pressure chemical vapor deposition (LPCVD) at pressure of 3 mtorr using titanium-tetra-iso-propoxide (TTIP), O2 and NbF5 as precursor, oxidant and dopant respectively. Resistivity beyond 100 Ωcm for undoped layer was decreased with increasing supply of the do…
Cellulose was extracted from torch ginger stems through alkali and bleaching treatments. The material obtained after each stage of the treatments was carefully characterised and its chemical composition was determined. Structural analysis was carried out by Fourier transform infrared (FTIR) spectroscopy. The results i…
This paper examines the influence of different warp densities on changes of relevant physical-mechanical properties of coated fabrics. Coating process of cotton fabric was performed by polyurethane coating.In order to examine the impact of polyurethane coating on the properties of multi-component materials, with a fab…
The self-association equilibrium constants, Kass, for the dimerization of some small oligothiophenes in acetone, acetonitrile and chloroform were measured by (1)H NMR spectroscopy. The gas phase interaction energies for some oligothiophene dimers were determined by computational quantum chemistry. The (1)H NMR results…
MnO2 as a material for supercapacitors is generally predicted to insert only one cation per unit cell. However, it is shown here to reversibly insert more than one cation in an organic electrolyte; however, in an aqueous electrolyte, the insertion ion is actually shown to be a combination of protons and cations.
Single crystal X-ray structures of two polymorphs of (2-fluoro-3-pyridyl)(2,2'-biphenyl)borinic 8-oxyquinolinate: orthorhombic (space group Pca21), and triclinic (space group P1̄) have been established and analysed. A fast rate of crystallization results in the orthorhombic polymorph, whereas slow crystallization give…
Calcium borohydride, Ca(BH4)2, one of the promising candidates for efficient hydrogen storage, has been synthesized successfully by the metathesis reaction between magnesium chloride and sodium borohydride in tetrahydrofuran in which the insoluble byproduct sodium chloride can be easily removed. And the hydrogen stora…
