Abstract Following the conventional carbon allotropes of diamond and graphite, fullerene, carbon nanotubes (CNTs) and graphene as 0D, 1D and 2D graphitic macromolecules have been discovered recently in succession, declaring the unlimited potential of carbon-based nanomaterials and nanotechnology. Although CNTs exhibit…
Molecular and nanoparticulate gold precursors for application in inkjet printing onto flexible substrates are discussed. The choice of stabilising ligands and the size of the nanoparticles influence the solution stability of the ink and their ability to form decorative or conductive functional films.
The electronic band structures of InN, GaN, and a hypothetical ordered ${\text{InGaN}}_{2}$ compound, all in the wurtzite crystal structure, are calculated using the quasiparticle self-consistent GW approximation. This approach leads to band gaps which are significantly improved compared to gaps calculated on the basi…
Abstract Hierarchical assemblies of nanofibres are ubiquitous in nature. Mineralized type I collagen is the basic building block of hierarchically organized, highly complex structures of bone tissue. As a biomaterial, collagen is widely utilized in biomimetic nanofibrous matrix fabrication due to its inherent biocompa…
Azo-phenol based receptors, having an azo core incorporated with naphthol and substituted (−H, −NO 2, −CH 3, and −OCH 3 ) benzothiazole units have been synthesized and their detailed optical properties have been investigated in different media. The nitro substituted azo derivative, 2, has shown, categorically, promisi…
Surface permanent magnet (SPM) machines can be designed with fractional slot-concentrated windings (FSCW) to achieve extended speed ranges. High-speed operation can lead to significant levels of proximity losses in the stator windings due to substantial spatial harmonic magnetic fields in the air-gap as well as the hi…
A method to determine tortuosity in a fibrous porous medium is proposed. A new approach for sample preparation and testing has been followed to establish a relationship between air permeability and fiberweb thickness which formed the basis for the determination of tortuosity in fibrous porous media. An empirical relat…
Due to the rapid development and growing societal role of nanoscience andnanotechnology (NST), these emerging fields are also growing ineducational importance. The demands for incorporating NST-related issuesinto curricula are often expressed with reference to the goals of scientificand technological literacy. This pa…
The management of voltage unbalance in a power system is supported by the knowledge on the contribution of a single unbalanced load/source to the total level of voltage unbalance observed at a Point of Common Coupling (PCC) in an interconnected power system with unbalanced loads distributed all over. The theoretical r…
New developments in the realm of skin rejuvenation such as phytotherapy are at an astounding increasing pace in the cosmeceutical market. Yet, many of these products that are classified as cosmeceuticals are tested less vigorously and do not have to be approved by the Food and Drug Administration to establish efficacy…
Nanotechnology has enabled a renaissance in the diagnosis of cancers. This is due, in part to the ability to develop agents bearing multiple functionalities, including those utilized for targeting, imaging, and therapy, allowing for the tailoring of the properties of the nanomaterials. Whereas many nanomaterials exhib…
With the purpose of studying the effect of stabilizing film morphology on polymer photovoltaic cell performance, the morphology and characteristics of bulk heterojunction devices fabricated using binary blends of an azide-functionalized graft copolymer of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C 61 -butyric ac…
Coacervate is defined as a polymer-rich dense phase, which remains in thermodynamic equilibrium with its low concentrated phase called the supernatant. The effect of ionic strength (I = 0-0.1 M NaCl) on the mechanism of surface patch binding-induced protein-polysaccharide interaction leading to complex coacervation, b…
Two series of pyrochemical reprocessing tests for oxide fuels, consisting of pretreatment, electrolytic reduction, and electrorefining processes, were conducted using ~100 g of UO2. In the pretreatment process, UO2 pellets of the starting material were oxidized into U3O8 powder, which simulated fuel decladding by volo…
Ozone is a strongly oxidative gas that is generally used in medical sterilization and decolorization of the effluent of textile spent dyebaths. Recent studies have reported the use of ozone to bleach textile fabrics. In this study, ozone was utilized in cotton preparation for greige, desized and scoured 100% cotton fa…
A theoretical formulation for modeling photoinduced nonequilibrium proton-coupled electron transfer (PCET) reactions in solution is presented. In this formulation, the PCET system is described by donor and acceptor electron-proton vibronic free energy surfaces that depend on a single collective solvent coordinate. Die…
A general symmetry analysis of the optical conductivity or scattering tensor is presented and used to rewrite the conductivity tensor as a sum of linear independent spectra multiplied by simple functions depending on the local magnetization direction. This allows one to describe the full, magnetization directional dep…
Surprisingly the strength of wet paper is still poorly understood. Here we show that the traditional explanation of the strength of wet paper is incorrect. Observations that the capillary force in fiber crossings in wet paper approaches zero as the water is evaporated show that they are not responsible for the strengt…
RNA interference is a post-transcriptional gene-silencing pathway induced by double-stranded small interfering RNA (siRNA). The potential use of siRNA as a therapeutic agent has attracted great attention as a novel approach to the treatment of several intractable diseases. Despite the rapid progress in the therapeutic…
Glycopolymers with a four-arm star architecture were prepared from poly(vinyl benzyl chloride) (PVBC) star polymers as reactive scaffold and 1-thio-β- d -glucose sodium salt. The star polymer was prepared via RAFT polymerization using 1,2,4,5-tetrakis(thiobenzoylthiomethyl)benzene as a rate-retarding RAFT agent at a p…
