In recent years, there has been increasing interest for the surface modification of biomaterials in order to improve their surface properties. The bare metal stents surface based on 3-dimethyl(methacryloyloxyethyl)ammonium propane sulfonate polymers has shown an excellent antifouling and blood compatibility by using s…
Double-wall carbon nanotubes (DWCNTs) with pyridyl units covalently attached to the external wall through isoxazolino linkers and carboxylic groups that have been esterified by pentyl chains are synthesized. The properties of these modified DWCNTs are then compared with an analogous sample based on single-wall carbon…
We derive the "conservation law" for nematic polymers in tensorial form valid for quadrupolar orientational order, in contradistinction to the conservation law in the case of polar orientational order. Due to microscopic differences in the coupling between the orientational field deformations and the density variation…
The control of enzymes by use of an external stimulus such as light enables the temporal and spatial regulation of defined chemical reactions in a highly precise manner. In this work we investigated and characterized the reversible photocontrol of a bacterial histone deacetylase-like amidohydrolase (HDAH) from Bordete…
Abstract A novel organic crystal, L‐lysine p‐nitrophenolate monohydrate (LLNP) has been grown successfully from an aqueous solution by the slow cooling method. Transparent single crystal of dimensions 22 × 12 × 12 mm 3 has been obtained. The single crystal X‐ray diffraction has shown that LLNP belongs to the orthorhom…
Photo-induced crystallization (PC) is studied in amorphous selenium (a-Se) films deposited on glass with and without intermediate layers of indium tin oxide or polymer material. The spatial profile of PC domains is examined by co-localized scanning atomic force microscopy and Raman mapping. We also explore the thermal…
Tempering is the final heat treatment applied to martensitic steels. In conventional martensitic stainless steels or in the newly developed supermartensitic grades, the mechanical properties are strongly influenced by tempering. In the present work, several tempering treatments were performed in a Ti alloyed supermart…
In this paper, we present ab initio calculations within density functional theory (DFT) to investigate structure, electronic and magnetic properties of Ru 2 CrZ ( Z = Si , Ge and Sn ) full-Heusler alloys. We have used the developed full-potential linearized muffin tin orbitals (FP-LMTO) based on the local spin density…
We introduce a simple theoretical model that describes the interaction of light with optical metamaterials in terms of interfering optical plane waves. In this model, a metamaterial is considered to consist of planar arrays of densely packed nanoparticles. In the analysis, each such array reduces to an infinitely thin…
Charge neutral bilayer graphene has a gapped ground state, as transport experiments have demonstrated. One plausible ground state is the layered antiferromagnetic spin density wave (LAF) state, where the spins in the top and bottom layers have the same magnitude with opposite directions. We propose that lightly charge…
In order to exploit the use of favorable electrostatic interactions between aromatic units in directing the assembly of donor-acceptor (D-A) dyads, the present work examines the ability of conjugated aromatic D-A dyads with symmetric side chains to exhibit solid-state polymorphism as a function of time during the soli…
Zinc hydroxystannate (ZHS) coated dendritic fibrillar calcium carbonate (ZHSCC-D) and ZHS coated cubic calcium carbonate (ZHSCC-C) were prepared in the water solution of cetyl trimethyl ammonium bromide (CTAB)/glycerin and in a pure water solution, respectively. Compared with the semirigid polyvinyl chloride (PVC) tre…
In a recent paper ('t Mannetje, D.; Banpurkar, A.; Koppelman, H.; Duits, M. H. G.; van den Ende, D.; Mugele, F. Electrically Tunable Wetting Defects Characterized by a Simple Capillary Force Sensor. Langmuir 2013, 29, 9944-9949), there are a few misconceptions regarding the interpretations of theories emanating from S…
Although homogeneity at the atomic level of CeO2-ZrO2 with a Ce/Zr atomic ratio close to unity is considered to be one of the main causes for the increased total oxygen storage capacity (OSC), the characterization approaches of homogeneity remain a major challenge. We propose a simple, yet effective method, to assess…
A new design for a quasi-solid-state Forster resonance energy transfer (FRET) enabled solar cell with unattached Lucifer yellow (LY) dye molecules as donors and CdS/CdSe quantum dots (QDs) tethered to titania (TiO2 ) as acceptors is presented. The Forster radius is experimentally determined to be 5.29 nm. Sequential e…
Research interest is growing in the potential to strategically mix selected polymers to modify properties and reduce the cost of resultant blends. Renewable resource-derived spinifex resin-based polyurethane (RPU) can be considered a potential bio-alternative to conventional petroleum-based polymers. However, its inhe…
In this paper, nanowire network anodized aluminum oxide (AAO) was fabricated by just adding a simple film-eroding process after the production of porous AAO. After depositing 50 nm of Au onto the surface, nanowire network AAO can be used as ultrasensitive and high reproducibility surface-enhanced Raman scattering (SER…
A new vanadium antimony selenite, VSb(SeO3)4, has been synthesized through a solid-state reaction by using V2O5, Sb2O3, and SeO2 as reagents. The crystal structure of VSb(SeO3)4 has been solved and refined by single-crystal X-ray diffraction. Whereas the starting V(5+) cation has been reduced to V(3+), the Sb(3+) cati…
Gel formation by low molecular mass gelators was investigated. The gelator was trans(RR)- or trans(SS)-N,N′-n-bromoalkanoyl-1,2-diaminocyclohexane (denoted as RR-CnBr or SS-CnBr, respectively; n = the number of carbon atoms in an alkanoyl group). When n was varied from 5 to 12, the gelators formed transparent or opaqu…
A compromise between competing forces dominates the diversity of material structures.
