Gold nanorods (NRs) in different arrangements represent the most plausible system for the creation of negative refractive index materials (NIMs) in the optical frequency range. Among other challenges, one of the major limitations of present day NIMs is their large amount of energy dissipation which frustrates the rest…
Wetting properties of polyethylene terephthalate (PET) and low-density polyethylene polymers have been investigated after treatment with a microwave (MW) plasma discharge at low pressure and a dielectric barrier discharge at atmospheric pressure. Experiments have also been carried out in situ with an atom source insta…
We report nanosecond time-resolved photoluminescence measurements on the isoelectronic series of oxygen deficient centers in amorphous silica related to silicon, germanium and tin atoms, which are responsible of fluorescence activities at approximately 4 eV under excitation at approximately 5 eV. The dependence of the…
This study was to decided the proper garment pressure level on the human body parts. Six volunteers (female: 30-40years) put on the same types of bands, a brief, and a non-woven gown. Garment pressure was measured in regular order with the elastic band on the human body parts such as the upper arm, the waist, the thig…
Herein, we show that current methodologies in atomistic simulations can yield reliable standard free energy values in aqueous solution for the transition from the dissociated monomeric form to the triple-helix state of collagen model peptides. The calculations are performed on a prototypical highly stable triple-helic…
The buildup mechanism of polypeptide multilayers prepared by the layer-by-layer deposition of a polyanion (poly(L-glutamic acid) (PGA)) and polycations (poly(L-lysine) (PLL), poly(D-lysine) (PDL), and copoly(DL-lysine)(PDLL)) was reinvestigated by using in situ ATR-IR spectroscopy. A difference spectral technique appl…
Abstract Some diamide derivatives have been prepared, characterized, and investigated as photostabilizers for plasticized poly(vinyl chloride) (PVC), containing dioctyl phthalate and dibutyl phthalate in a concentration of 30% by weight of the polymer. The stabilizing efficiency of the prepared diamides was evaluated…
The brain is one of the least accessible organs of the body, thus making the delivery of neurotherapeutics almost a challenge. Despite its relatively high nutrient support and exchange requirements, the uptake of any compound is strictly regulated by the blood brain barrier (BBB). As a consequence, BBB prevents effect…
The imaging properties of a uniaxial anisotropic slab lens, where the dielectric tensor components are of the opposite sign, are studied as a function of the structure parameters. While hypothetical parameters yield various levels of performance, a design principle to achieve good subwavelength resolution is suggested…
Gene rv0802c from Mycobacterium tuberculosis encodes a 218-amino-acid protein and is annotated as a hypothetical protein with homology to GCN5-related N-acetyltransferases. The structure of Rv0802c was determined in an unliganded form to 2.0 A resolution utilizing single-wavelength anomalous dispersion from a samarium…
Vertical ZnO nanowires were uniformly fabricated on a tin-doped indium oxide (ITO) glass substrate by low-temperature thermal decomposition. The morphology and structure of ZnO nanowires were analysed by scanning electron microscopy, x-ray diffraction (XRD) and transmission electron microscopy (TEM). The diameter and…
This paper deals with the preparation and optical analysis of Er3+ (0.2 mol%) boro-fluoro-phosphate glasses in the following glass compositions: Series A: 69.8 B2O3–10 P2O5–10(ZnO/CdO/TeO2)–10 AlF3 Series B: 69.8 B2O3–10 P2O5–10(ZnO/CdO/TeO2)–10 LiF Measured Vis-NIR absorption spectra of Er3+:boro-fluoro-phosphate gla…
The transition from the atomically ordered B2-phase to the chemically disordered A2-phase and the concomitant deformation-induced ferromagnetism have been investigated in bulk polycrystalline Fe 60 Al 40 (at.%) alloys subjected to compression processes. A detailed correlation between structural, magnetic and mechanica…
A great deal of attention has been focused on exploiting novel methods to fabricate thin carbonaceous capsules from multiple components for advanced materials. A layer-by-layer (LbL) method is therefore being introduced to synthesize thin and multi-carbon nanotube (CNT)-based hollow capsules from CNT complexes with ca…
Polymorphic transformation of pravastatin sodium in a mixture of isopropanol and water was studied by use of online focused beam reflectance measurement (FBRM) and particle vision measurement (PVM). It is shown that the form A polymorph transformed to the stable polymorph, form B. It was speculated that in the transfo…
We derive the structural principles of polyhedral allotropes of phosphorus, introducing three distinct families of black phosphorus nanostructures. The predicted tetrahedral, octahedral, and icosahedral phosphorus cages can also be considered as phosphorus fullerenes. Phosphorus cages up to P(888) are systematically i…
Amphiphilic scorpion-like macromolecules (AScMs), that self-assemble as nanocarriers, were evaluated for intracellular delivery. To qualitatively examine the intracellular fate of AScMs in human umbilical vein endothelial cells (HUVECs), representative polymers (M 12 P 5 ) were labeled with a fluorescent dye, fluoresc…
Irradiation of 2-diazo-3-oxochlorins (200 W, lambda > or = 345 nm, 10 degrees C) in the presence of nucleophilic and biomimetic substrates 1-butanol, tosylhydrazine, or tetrahydrofurfuryl alcohol generates Wolff-rearranged, pyrrole ring-contracted azeteoporphyrinoids in 11-34% yield, with the corresponding hydroxyporp…
The synthesis of highly ordered monolayers of metallic nanoclusters by a buffer-layer assisted growth (BLAG) route is introduced and investigated. The focus is on clusters of Co deposited onto mechanically stable, periodically corrugated boron-nitride layers by repeated BLAG cycles. The approach combines the advantage…
In this paper, the dynamic assembly of toroidal micelle structures of amphiphilic triblock copolymers in dilute solution has been investigated using dissipative particle dynamics simulations. The amphiphilic molecule is represented by a coarse-grained model, which contains hydrophilic and hydrophobic particles. Some m…
