A new method of extracting effective permittivity and permeability of metamaterials has been developed in this paper. Scattering parameters are used to represent effective wave impedance and refractive index of the metamaterials. Considering analytical continuation of effective refractive index of the metamaterials in…
Various systems containing the [ML5NO] molecule, where M = Fe, Ru, ... and L = F, Cl, ..., exhibit switching under continuous light (CW) irradiation between the ground-state nitrosyl (GS), isonitrosyl (MSI), and side-on (MSII) configurations. The metastable populations, however, are often limited to a few percent. The…
Although polyhydroxyalkanoate (PHA) accumulation and mobilization are one of the most general mechanisms for haloarchaea to adapt to the hypersaline environments with changeable carbon sources, the PHA mobilization pathways are still not clear for any haloarchaea. In this study, the functions of five putative (R)-spec…
Abstract CuCr 0.93 Mg 0.07 O 2 thin films with improved optoelectronic properties were deposited by reactive magnetron sputtering on fused quartz substrates. The influence of annealing temperature under vacuum on optoelectronic properties of the films was investigated. The amorphous films annealed under vacuum at temp…
We have studied copolymer dendrimer structure: carbosilane dendrimers with terminal phenylbenzoate mesogenic groups attached by poly(ethylene) glycol (PEG) spacers. In this system PEG spacers are additional tuning to usual copolymer structure: dendrimer with terminal mesogenic groups. The dendrimer macromolecules were…
Hydrogen permeation of two kinds of ferritic steel with different level of 2nd phase particles are compared utilising electrochemical permeation technique evaluated under various loads. This study indicates that tensile stress in plastic domain induces expansion of the interface between the 2nd phase particles and ste…
CdSe nanoparticles were synthesized by green route and chemical route methods. In the green route method the samples were capped by starch and in the chemical route method the samples were capped by mercaptoacetic acid (MAA). The samples were characterized by powder X- ray diffraction (XRD) and transmission electron m…
We demonstrate the deposition of crystalline palladium nanoparticles on graphene nanoplatelets (Pd/graphene) via atmospheric pressure atomic layer deposition (ALD) carried out in a fluidized bed reactor. The nucleation and growth of Pd nanoparticles on the inert graphene surface was enabled by applying an ozone pretre…
Chitosan is known for its hemostatic and antimicrobial properties and might be useful for temporary coating of removable dentures or intraoral splints to control bleeding after oral surgery or as a supportive treatment in denture stomatitis. This study investigated a new method to adhere chitosan to polymethyl methacr…
We experimentally verify a new class of coherent absorbers based on guided-mode resonance effects in periodic thin films. We design a silicon-based resonant absorber that is fabricated and tested near the 1300-nm wavelength. Implementing phase control, the device can, in principle, be switched between full absorption…
The objective of this research is to evaluate the effect of the addition of lemongrass essential oil (LGO) on the characteristics and antimicrobial properties of cassava starch based ï¬lms. Edible films were prepared from a mixture of cassava starch and glycerol. LGO was added to edible films as natural antimicrobial…
3D cube-shaped composites and carbon microparticles with hierarchically porous structure are prepared by a facile template-free synthesis route. Via the coordination of zinc acetate dihydrate and squaric acid, porous 3D cubic crystalline particles of zinc squarate can be obtained. These are easily transformed into the…
Research focused on assessing potential consumer exposure to nanoparticles released from nano-enabled food-contact materials (FCMs) has often reached conflicting conclusions regarding the detection of migrating nanoparticles. These conflicting conclusions, coupled with the potential for nanoparticles to be unstable in…
Following the implantation of biodegradable vascular grafts, macrophages and fibroblasts are the major two cell types recruited to the host-biomaterial interface. In-vitro biocompatibility assessment usually involves one cell type, predominantly macrophages. In this study, macrophage and fibroblast mono- and co-cultur…
The interaction between amphiphiles and polyelectrolytes has been widely investigated in recent years due to their potential application in industry and medicine, with special focus on gene therapy. The cationic lipid dioleoyl trimethylammonium propane, DOTAP, and the oppositely charged polyelectrolytes, sodium poly(a…
A key element of materials discovery and design is to learn from available data and prior knowledge to guide the next experiments or calculations in order to focus in on materials with targeted properties. We suggest that the tight coupling and feedback between experiments, theory and informatics demands a codesign ap…
The electrical dc transport properties of hexagonal magnetic equiatomic alloys of nominal composition ${\mathrm{Mn}}_{1\ensuremath{-}x}{\mathrm{Fe}}_{x}\mathrm{NiGe}$ $(x=0.2\phantom{\rule{4pt}{0ex}}\text{and}\phantom{\rule{4pt}{0ex}}0.25)$ have been investigated experimentally as well as theoretically using first-pri…
Background/Objectives: Nanoparticles possess unique properties due large surface to volume ratio and quantum confinement effect. ZnO is suitable for laser diodes, LEDs and Photodetectors due to wide direct band gap, high melting point, high thermal conductivity etc. Methods/Statistical analysis: Pure Zinc oxide and Al…
The FP7 Sanowork project was aimed to minimise occupational hazard and exposure to engineered nanomaterials (ENM) through the surface modification in order to prevent possible health effects. In this frame, a number of nanoparticles (NP) have been selected, among which zirconium (ZrO2) and titanium (TiO2) dioxide. In…
In this review, we survey recent advances in the field of molecular plasmonics beyond the traditional sensing modality. Molecular plasmonics is explored in the context of the complex interaction between plasmon resonances and molecules and the ability of molecules to support plasmons self-consistently. First, spectros…
