In this paper, the effects of the molecular weight of a polycarbonate (PC) matrix on the phase morphology and optical properties of a PC/styrene-co-acrylonitrile (SAN) blend were investigated. A scanning electron microscope is used to analyze the phase morphology of the blends, and Mie scattering theory is used to ana…
This research considered cementitious composites reinforced with macroscale, microscale and nanoscale fibres. Ten test groups including a combination of the multiscale fibres (steel fibres, polyvinyl alcohol (PVA) fibres and carbon nanofibres (CNFs)) were studied. An experimental programme was developed to determine t…
Despite the fact that silicon material can be synthesized from various sources, deriving them from silica resources is of strategic significance for the industrial processing. Here a low-cost nano/micro structure of Si–CNT was derived from nano-SiO2 and multiwall carbon nanotubes (MWCNTs) with simple methods. By emplo…
We report the use of epsilon near zero (ENZ) metamaterial to control spontaneous emission from Zinc-Oxide (ZnO) excitons. The ENZ material consists of alternating layers of silver and alumina with subwavelength thicknesses, resulting in an effective medium where one of the components of the dielectric constant approac…
Cocoons of Antheraea assamensis (muga) silkworm were treated with different classes of natural-acidic (Citrus limon and Dillenia indica) and alkaline (Musa balbisiana) materials with the aim to elucidate their effectiveness as degumming agents. The tensile strength of silk fibers increased significantly after bio-degu…
BACKGROUND: There are still numerous protein subfamilies within families and superfamilies that do not yet have conclusive empirical experimental evidence providing a specific function. These proteins persist in databases with the annotation of a specific 'putative' function made by association with discernible featur…
The actual grinding result of ceramics has not been well predicted by the present mechanical models. No allowance is made for direct effects of materials microstructure and almost all the mechanical models were obtained based on crystalline ceramics. In order to improve the mechanical models of ceramics, surface grind…
Abstract A highly electron‐deficient C3‐symmetric tris(bipyridyl) ligand was prepared in four steps and used for the coordination of Fe(OTf)2, thereby resulting in the homochiral assembly of a new family of robust tetrahedral M4L4 cages. This homochiral T‐symmetric cage containing a relatively large cavity of 330 Å3 i…
ZnIn2S4 (ZIS) crystalline thin film was prepared by novel spray pyrolysis technique. The as-deposited ZIS film was characterized by X-ray diffraction technique, ultraviolet–visible–near infrared spectroscopy, field emission scanning electron microscopy and energy dispersive analysis by X-rays. X-ray diffraction patter…
A phytochemical investigation of the whole plants of Adonis multiflora Nishikawa & Koki Ito. resulted in the isolation and identification of two new cardenolides--adonioside A (1) and adonioside B (6)--as well as four known cardenolides: tupichinolide (2) oleandrine (3), cryptostigmin II (4), and cymarin (5). Their st…
Abstract Tendon injuries occur commonly in sports and workplace. Tendon-derived stem cells (TDSCs) have great potential for tendon healing because they can differentiate into functional tenocytes. To grow TDSCs properly in vivo, a scaffold is needed. Silver nanoparticles (AgNPs) have been used in a range of biomedical…
In this study, Cu/TiO2 and Cu/g-C3N4 catalysts were tested for CO2 reduction to methanol. The catalysts were prepared by the wet impregnation method and, characterized by XRD and FESEM. The product identification and yield were determined using a GC with FID. The CO2 photoreduction process was performed in each of the…
The surface properties of fibers can be regarded as instrumental toward innovative functional textiles as applied in many high-end industries. Accordingly, not only the modification of surface chemistry, but also of the physical and morphological properties is an important objective in modern materials science and tec…
The preferential solvation parameters (δx1,3) of indomethacin (IMC) in 1,4-dioxane + water binary mixtures were derived from their thermodynamic properties by means of the inverse Kirkwood–Buff integrals method. δx1,3 is negative in water-rich and 1,4-dioxane-rich mixtures but positive in cosolvent compositions from 0…
For a ternary alloy system promising for obtaining the so-called bulk metallic glasses (BMGs), the first priority issue is to predict the favored compositions, which could then serve as guidance for the appropriate alloy design. Taking the Al-Ni-Y system as an example, here we show an atomistic approach, which is deve…
We propose a scheme using cooperative interaction of antiphase resonance modes to enhance optical trapping in plasmonic nanostructures. This is implemented with a subwavelength array of asymmetric binary nanogrooves (e.g. different depths) in metal. When damping and inter-coupling of antiphase fields in the nanogroove…
Tourmalines with Al 3+ , Mg 2+ , Fe 3+ , Fe 2+ , Mn 2+ , V 3+ , and Cr 3+ cation disorder at the two octahedrally coordinated sites ( Y , Z ) have recently been described. Their complete structural and compositional description enabled a detailed statistical study of Mg 2+ , Al 3+ , and Fe 2+ disorder reactions. The s…
Cadaverine has the potential to become an important platform chemical for the production of nylon. Previously, a system that overexpresses the Klebsiella oxytoca lysine decarboxylase in Escherichia coli was engineered. The system was optimized by codon optimization, and tuning the expression level of the gene by testi…
This paper presents a green and cost-effective recipe for the synthesis of blue-emitting ZnO nanoparticles (NPs) using cellulose bio-templates. Azadirachta indica (neem) leaf extract prepared in different solvents were used as biological templates to produce nanostructures of wurtzite ZnO with a particle size ~12-36 n…
We examine the fracture of a quasi-two-dimensional surfactant-laden aqueous foam under an applied driving pressure, using a network modelling approach developed for metallic foams by Stewart & Davis (J. Rheol., vol. 56, 2012, p. 543). In agreement with experiments, we observe two distinct mechanisms of failure analogo…
