The synthesis of bifunctional Au/Pt/Au nanoraspberries for use in quantitative in situ monitoring of platinum-catalyzed reactions by surface-enhanced Raman scattering (SERS) is presented. Highly convolved SERS spectra of reaction mixtures can be decomposed into the contributions of distinct molecular species by multiv…
The band structure of PbTe can be manipulated by alloying with MgTe to control the band degeneracy. This is used to stabilize the optimal carrier concentration, making it less temperature dependent, demonstrating a new strategy to improve overall thermoelectric efficiency over a broad temperature range.
Piezoresponse force microscopy (PFM) detects the local piezoelectric deformation of a sample caused by an applied electric field from the tip of a scanning force microscope. PFM is able to measure deformations in the sub-picometre regime and can map ferroelectric domain patterns with a lateral resolution of a few nano…
Abstract The use of natural fibers to reinforce polymers is a well‐established practice, and biocomposites are increasingly used in sectors such as automotive and construction. Green composites are a specific class of biocomposites, where a bio‐based polymer matrix is reinforced by natural fibers, and they represent a…
A 3D graphene architecture can be prepared via an in situ self-assembly of graphene prepared by a mild chemical reduction. Fe(3) O(4) nanoparticles are homogeneously dispersed into graphene oxide (GO) aqueous suspension and a 3D magnetic graphene/Fe(3) O(4) aerogel is prepared during the reduction of GO to graphene. T…
Distortions of the electronic density of states (DOS) are a potent mechanism to increase the thermopower of thermoelectric semiconductors, thereby increasing their power factor. We review band-structure engineering approaches that have been used to achieve this, resonant impurity levels, dilute Kondo effects, and hybr…
We are delighted to present a special issue on the subject of functional residues of proteins. Finding focused articles within the time frame of a special issue is always challenging, which is further compounded by authors' reluctance in making their contributions to new journals. We have been fortunate enough that so…
Abstract The foaming of PVC (poly(vinyl chloride)) plastisols is a complex combination of simultaneous processes, involving the curing and structural changes of the plastisol, the gas generation and the foam formation. Our comprehensive study of such processes and of the influence of plasticizer on the foam quality ha…
Pd(II)/Fe(II)-mediated three-dimensional bimetal-organic multilayers have been constructed on the substrate surfaces with the use of a polymeric ligand of terpyridine-contained poly(vinylpyridine) (PVPTPy) derivative as a linker as well as inorganic salts of Na2PdCl4 and Fe(BF4)2 as connectors. The assembly process wa…
Abstract The structural and thermal characteristics of poly( L ‐lactic acid)/layered‐silicate hybrid materials that were produced via two different routes, namely by solvent casting and by melt mixing, were compared in association with the degree of clay modification. Investigation of the produced materials' structure…
SUMMARY Thermoplastic composites demand constant improvements in fire retardant and mechanical properties to fulfil their full market potential, especially in demanding sectors such as rail, aerospace and infrastructure, where fire performance is critical. The aim of this work is to understand the effect of reinforcin…
Several experimental studies have shown the presence of spatially inhomogeneous phase coexistence of superconducting and non-superconducting domains in low dimensional organic superconductors. The superconducting properties of these systems are found to be strongly dependent on the amount of disorder introduced in the…
Peanut shaped PbS nanocrystals are synthesized and their self-assemblies have been studied by means of solvent evaporation. Multi-scale ordered self-assemblies of PbS nanopeanuts have been achieved by solvent evaporation route and interparticle interactions in the solution phase. The self-assembly mechanism produces c…
We propose a VHDL-AMS model for a dual gate bilayer graphene field effect transistor (GFET). The GFET model in consideration is based on closed analytical derivations for a graphene device model. The analytical derivations describe the I-V characteristics of the transistor operating at the various regions. An up-kick…
Weak localization is studied in two high-quality epitaxial graphene samples grown on silicon-faced 6H-SiC substrates. Following the methodology of Kozikov et al (2010 Phys. Rev. B 82 075424), we measured the temperature dependence of carrier conductivity at zero and low magnetic ( B ) fields. In both samples, a logari…
Abstract Biocomposites were successfully prepared by the reinforcement of soy protein isolate (SPI) with different weight fractions of woven flax fabric. The flax‐fabric‐reinforced SPI‐based composites were then arylated with 2,2‐diphenyl‐2‐hydroxyethanoic acid (DPHEAc) for 4 h to obtain arylated biocomposites. A new…
We have synthesized CdSe nanocrystals (NCs) possessing a trioctylphosphine surface passivation layer and modified with amphiphilic molecules to form a surface bilayer. The NCs covered with single amphiphiles are not stable in aqueous solution, but a mixed amphiphilic system is shown to provide stability in solution ov…
Problem statement: The characterization of smectitic clays has been traditionally made using physical and chemical methods which are time-consuming and require costly equipment. Adsorption of methylene blue by these clays has been introduced as a quick and cheap method for the estimation of cation exchange capacity an…
In this paper, we present the pore formation on inorganic–organic hybrid material, ORMOCER©, by reactive ion etching. ORMOCERs are composed of inorganic backbone where organic side groups are attached by cross-linking. Etching of ORMOCER in oxygen plasma generates porous materials with different pore sizes depending o…
In order to understand the origin of the tacticity splitting in the NMR spectra of poly(lactic acid), monomer and dimer model compounds were synthesized and their 1 H and 13 C NMR chemical shifts were observed. Two stable conformations were obtained from Ramachandran map calculated as a function of the internal rotati…
