We describe plasmonic interactions in suspended gold bowtie nanoantenna leading to strong electromagnetic field (E) enhancements. Surface-enhanced Raman scattering (SERS) was used to demonstrate the performance of the nanoantenna. In addition to the well-known gap size dependence, up to 2 orders of magnitude additiona…
ModBase (http://salilab.org/modbase) is a database of annotated comparative protein structure models. The models are calculated by ModPipe, an automated modeling pipeline that relies primarily on Modeller for fold assignment, sequence-structure alignment, model building and model assessment (http://salilab.org/modelle…
The valence-band electronic structure of a decagonal Ni-rich Al–Co–Ni quasicrystal, Al72Co8Ni20, was investigated using soft X-ray photoelectron spectroscopy. In particular, the energy distributions of the transition metal 3d bands were determined from the Co and Ni 2p–3d resonance photoemission and compared with thos…
We present a method to synthesize submicrometer germanium dioxide on porous silicon (PS) by electrochemical deposition. The PS was electrochemically prepared in HF based electrolyte. was directly hydrolyzed by hydrogen peroxide to produce pure and then electrochemically deposited on PS. The scanning electron microscop…
Abstract Infiltration of regioregular poly(3‐hexyl thiophene) (RR P3HT) polymer into ordered TiO 2 nanotube arrays is confirmed by UV–Vis absorption spectrometer measurement, time‐of‐flight secondary ion mass spectrometer (TOF‐SIMs) depth profiling and transmission electron microscopy (TEM), and scanning electron micr…
Natural fibre composites were manufactured with epoxidized hemp oil (EHO) and epoxidized linseed oil (ELO) blended with a commercial epoxy resin. Randomly orientated short hemp fibres were used as the reinforcing fibres. The effects of EHO/ELO addition, fibre weight fraction and alkali treatment of the hemp fibre were…
Kinetic inductance is an important property of carbon nanotubes (CNTs) in high-frequency applications. However, disagreements exist in whether the kinetic inductance of CNTs is present in the diffusive transport regime. In this paper, we fabricated the horizontally aligned multiwalled nanotube (MWNT) arrays on silicon…
The inhibition of the corrosion of zinc in 0.4 M HCl by (Z)-2-(2-(4-methoxyphenyl)hydrazono)-3-(5,6,7,8-tetrahydrocarbazol-9-yl)-3-oxopropanenitrile(1),(Z)-2-(2-(4-chlorophenyl)hydrazono)-3-(5,6,7,8-tetrahydrocarbazol-9-yl)-3-oxopropanenitrile(2),(Z)-2-(2-phenylhydrazono)-3-(5,6,7,8-tetrahydrocarbazol-9-yl)-3-oxopropa…
A method to fabricate low reflectivity poly-crystalline Si (poly-Si) surface structures for solar cells has been developed by use of catalytic activity of a metal film. Immersion of Si contacted with platinum (Pt) films in hydrogen peroxide plus hydrofluoric acid solutions results in etching of Si only in the contacte…

Abstract The synthesis of oxidorhenium(V) complexes with tridentate and potentially tetradentate ligands of the type [ReOX 2 (L)] {X = Cl or Br; L = 2‐[CH 2 N(Me)CH 2 CH 2 OCH 3 ]‐4,6‐di‐ t Bu‐phenolate, 2‐[CH 2 N(Me)CH 2 CH 2 SCH 2 CH 3 ]‐4,6‐di‐ t Bu‐phenolate, 2‐[CH 2 N(Me)CH 2 CH 2 N(CH 3 ) 2 ]‐4,6‐di‐ t Bu‐phenol…
Threonine synthase (TS), which is a pyridoxal 5'-phosphate (PLP)-dependent enzyme, catalyzes the elimination of the γ-phosphate group from O-phospho-L-homoserine (OPHS) and the subsequent addition of water at Cβ to form L-threonine. The catalytic course of TS is the most complex among the PLP enzymes, and it is an int…
We report the destabilization of the lattice collapsed phase of ${\text{LaCo}}_{2}{\text{Ge}}_{2}$ due to $X\text{\ensuremath{-}}X$ $(X={\text{Ge}}_{1\ensuremath{-}x}{\text{P}}_{x})$ dimer breaking in the ${\text{LaCo}}_{2}{({\text{Ge}}_{1\ensuremath{-}x}{\text{P}}_{x})}_{2}$ solid solution. The magnetic properties of…
According to data from the World Health Organization (WHO), one billion adults that are approximately overweight currently exist in the world, of which three hundred million are obese. These numbers led to the finding that obesity appears as a major global epidemic, affecting countries in all stages of development. In…
The isostatic jamming limit of frictionless spherical particles from Edwards' statistical mechanics [Song et al., Nature (London) 453, 629 (2008)] is generalized to arbitrary dimension d using a liquid-state description. The asymptotic high-dimensional behavior of the self-consistent relation is obtained by saddle-poi…
The Meissner effect has been studied in $\text{Ba}{({\text{Fe}}_{0.926}{\text{Co}}_{0.074})}_{2}{\text{As}}_{2}$ and ${\text{Ba}}_{0.6}{\text{K}}_{0.4}{\text{Fe}}_{2}{\text{As}}_{2}$ single crystals and compared to well known, type-II superconductors ${\text{LuNi}}_{2}{\text{B}}_{2}\text{C}$ and ${\text{V}}_{3}\text{S…
Abstract BODIPY–subporphyrin hybrids bridged by a 1,4‐biphenylene or 1,4‐diphenylethynylene spacer were synthesized either by the palladium‐catalyzed Suzuki–Miyaura reaction or the Sonogashira reaction. Their structural and optical properties were examined with respect to the bridge and BODIPY structures. In all cases…
Abstract The synthesis and characterizations of fluorinated telomers based on vinylidene fluoride (VDF) by iodine transfer polymerization (ITP) are presented. These telomers were prepared in the presence of ω‐iodoperfluorinated functional chain transfer agents, C 6 F 13 I or C 4 F 9 I. ITPs were initiated by thermal d…
The outstanding properties of single-walled carbon nanotubes (CNTs) are often impaired by the presence of structural defects, such as vacancies, as consequence of peculiar growth techniques or electron irradiation. However, the changes in the electronic structure due to the presence of defects can also induce the form…
A simple and efficient route to prepare supported nanocrystalline oxides is presented. The synthesis procedure, i.e. in situ autocombustion of a glycine complex, allows the production of nanocrystals in a porous matrix presenting larger pore size. An example of successful formation of 2-5 nm nanocrystals is given for…
