We propose a new bulk approach to the electromagnetic (EM) modeling of nanotubes (NTs) and nanowires (NWs) in arrays or bundles of arbitrary shape and size. The purpose of this model is to enable feasible and efficient EM analysis of electronics designs incorporating these novel materials by using the available softwa…
Abstract Besides their importance for quantum information processing, NV defects are crucial agents for the diffusion and aggregation of nitrogen in diamond. In the absence of transition metals, it is thought that the first stage of nitrogen aggregation, where close neighbour nitrogen pairs are formed, is mediated by…
Highly emissive ultraviolet ZnSeS nanocrystals (NCs), with a core-shell-like structure, were designed and synthesized via a one-step noninjection approach in 1-octadecene (ODE). These ultraviolet ZnSeS NCs exhibit bright bandgap emission with high color purity and little trap emission. With full width at half-maximum…
A comprehensive review of cutting-edge solid state research, focusing on its prominent example - quantum dot nanostructures - this book features a broad range of techniques for fabrication of these nano-structured semiconductors and control of their quantum properties. Written by leading researchers, the book consider…
Fully ab initio treatment of complex solid systems needs computational software which is able to efficiently take advantage of the growing power of high performance computing (HPC) architectures. Recent improvements in CRYSTAL, a periodic ab initio code that uses a Gaussian basis set, allows treatment of very large un…
Conformational sampling is one of the bottlenecks in fragment-based protein structure prediction approaches. They generally start with a coarse-grained optimization where mainchain atoms and centroids of side chains are considered, followed by a fine-grained optimization with an all-atom representation of proteins. It…
There exist experiments indicating that at certain conditions, such as an appropriate substrate, a gap of the order of 10 meV can be opened at the Dirac points of a quasiparticle spectrum of graphene. We demonstrate that the opening of such a gap can result in the appearance of a fingerprint bump of the Seebeck signal…
A new generation of entirely biodegradable and bioactive composites with polylactic acid (PLA) or poly-ε-caprolactone (PCL) as the matrix and bioplastic flax fibers as reinforcement were analyzed. Bioplastic fibers contain polyhydroxybutyrate and were obtained from transgenic flax. Biochemical analysis of fibers revea…
The role of core block size dispersity on the rate of molecular exchange in spherical micelles formed from 1% by volume poly(styrene- b -ethylenepropylene) (PS-PEP) diblock copolymers in squalane (C 30 H 62 ) was investigated using time-resolved small-angle neutron scattering (TR-SANS). Separate copolymer solutions (t…
We report a novel continuous and sensitive fluorescence turn-on assay for ACPs, which consists of a cationic conjugated polyelectrolyte (PPE4+) and a commonly used phosphatase substrate p-nitrophenyl phosphate (pNPP). The kinetics of the ACP catalyzed hydrolysis of the substrate pNPP was monitored by the fluorescence…
A noble metal (NM) can stabilize monolayer-dispersed surface oxide phases with metastable nature. The formed "oxide-on-metal" inverse catalyst presents better catalytic performance than the NM because of the introduction of coordinatively unsaturated cations at the oxide-metal boundaries. Here we demonstrate that an u…
Block copolymers with tunable compositions offer the ability to directly control the interaction strength between the two blocks and therefore polymer properties. The miscibility of an A–B block copolymer can be increased by introducing B or B-like comonomers into the A block, and literature has shown that both the am…
We systematically investigate the photoexcited (PE) quasiparticle (QP) relaxation and low-energy electronic structure in electron doped Ba(Fe${}_{1\ensuremath{-}x}$Co${}_{x}$)${}_{2}$As${}_{2}$ single crystals as a function of Co doping, $0\ensuremath{\le}x\ensuremath{\le}0.11$. The evolution of the photoinduced refle…
A series of nanostructured CeO2/Clinoptilolite catalysts with different loadings of ceria were prepared by redox reaction followed by wet impregnation method and tested for oxidation of xylene. The catalysts were characterized by XRD, FESEM, BET, FTIR, and TG‐DTG analysis. XRD data confirmed the formation of CeO2 as t…
We demonstrate wide-range diameter modulation of vertically aligned single-walled carbon nanotubes (SWNTs) using a wet chemistry prepared catalyst. In order to ensure compatibility to electronic applications, the current minimum mean diameter of 2 nm for vertically aligned SWNTs is challenged. The mean diameter is dec…
A simulation study of liquid drops on inclined surfaces is performed in order to understand the evolution of drop shapes, contact angles, and retention forces with the tilt angle. The simulations are made by means of a method recently developed for dealing with contact angle hysteresis in the public-domain Surface Evo…
Angiogenesis, the formation of new blood vessels by sprouting from pre-existing ones, is critical for the establishment and maintenance of complex tissues. Angiogenesis is usually triggered by soluble growth factors such as VEGF. However, geometrical cues also play an important role in this process. Here we report the…
In this study, the influence of coupling agent concentration (0 and 3 wt%), wood fiber content (50, 60, 70, and 80 wt%), and size (40–60, 80–100, and 160–180 mesh) on the mechanical properties of wood/high-density-polyethylene (HDPE) composites (WPCs) was investigated. WPC samples were prepared with poplar wood-flour,…
We demonstrate a direct fabrication of PbS nanocube supercrystals without size-selection pretreatment on the building blocks. Electron microscopic and synchrotron small angle X-ray scattering analyses confirm that nanocubes pack through a tilted face-centered-cubic (fcc) arrangement, that is, face-to-face along the <1…
In the present research work, biosynthesis of silver nanoparticles and its activity on bacterial pathogens were investigated. Silver nanoparticles were rapidly synthesized using Urospora sp. and the formation of nanoparticles was observed within 30 min. The results recorded from UV–vis spectrum, Fourier Transform Infr…
