Porphyrins have been widely used for many years as functional materials for chemical sensors. Their outstanding chemical features are balanced by some restrictions in terms of transduction techniques. In particular, porphyrin layers are barely conductive, with the consequence that the fabrication of porphyrin based ch…
Abstract In this study, titanium dioxide (TiO 2 ) or nano titanium dioxide (nano‐TiO 2 ) was used as a cocatalyst in the flame‐retardant (FR) formulation of N ‐methylol dimethylphosphonopropionamide (Pyrovatex CP New, FR), melamine resin [Knittex CHN, crosslinking agent (CL)], and phosphoric acid (PA) for cotton fabri…
In this research, the effects of bamboo charcoal on soil contaminant accumulation, soil fertility and plant growth were investigated. The results indicated that sludge composted with bamboo charcoal (BCS) significantly increased plant growth and decreased the mobility of Zn, Cu and polycyclic aromatic hydrocarbons (PA…
The use of hollow/microporous yarns plays an important role in enhancing the thermo‐physiological comfort properties of fabrics. Depending on structural variations in hollow yarn, heat and moisture regulation behaviours of fabrics can be affected significantly. In this study, three types of hollow cotton yarn fabrics,…
In this paper, we proposed new structured metamaterials with multi-helical nanowires to construct circular polarizers with higher S/N ratios. Compared with the single-helical ones reported by J. K. Gansel et al. [Science 325, 1513 (2009), Opt. Express 18, 1059 (2010)], which has a lower S/N ratio (~10 dB) due to the h…
Helical inorganic nanostructures have received great attention due to their unique structures that could be interesting for both fundamental research and nanodevice applications. Using a tube-in-tube laser ablation chemical vapor deposition (CVD) method with gold nanoparticles as the catalysts, we reported the synthes…
Adding a small amount of an immiscible liquid to a suspension can change it from a viscous fluid to an elastic gel.
Abstract Gd 2 O 3 nanoparticles surface‐modified with IPDI were compounded with epoxy. IPDI provided an anchor into the porous Gd 2 O 3 surface and a bridge into the matrix, thus creating strong bonds between matrix and Gd 2 O 3 . 1.7 vol.‐% Gd 2 O 3 increased the Young's modulus of epoxy by 16–19%; the surface‐modifi…
We performed angle-resolved photoelectron spectroscopy (ARPES) studies on mechanically detwinned BaFe${}_{2}$${\mathrm{As}}_{2}$. We observe clear band dispersions, and the shapes and characters of the Fermi surfaces are identified. Shapes of two-hole pockets around the $\ensuremath{\Gamma}$ point are found to be cons…
A promising strategy for the selective growth of ZnO nanorods on SiO 2 /Si substrates using a graphene buffer layer in a low temperature solution process is described. High densities of ZnO nanorods were grown over a large area and most ZnO nanorods were vertically well-aligned on graphene. Furthermore, selective grow…
Fibrous materials experience compression in many important industrial and technical applications. They are known to undergo a viscoelastic response in such circumstances, exhibiting phenomena such as dependence on compaction velocity, stress relaxation and stress–strain hysteresis. In this paper, a model has been deve…
Poly(caprolactone- b -2-vinylpyridine) (PCL-P2VP) coated with folate-conjugated M13 (FA-M13) provides a nanosized delivery system which is capable of encapsulating hydrophobic antitumor drugs such as doxorubicin (DOX). The DOX-loaded FA-M13-PCL-P2VP assemblies had an average diameter of approximately 200 nm and their…
Oil palm empty fruit bunches (EFB)/woven jute fibres (Jw) reinforced epoxy hybrid composites were prepared by hand lay-up technique by keeping the EFB/ woven jute fibre weight ratios constant, i.e. 4:1. By combining oil palm EFB and woven jute fibre, it is possible to take advantage of both fibres while at the same ti…
AIMS: This research investigated the effect of sonication at frequencies of 20, 40 and 580 kHz and approximately the same acoustic intensity on the viability and declumping of two micro-organisms (Escherichia coli and Klebsiella pneumonia). METHODS AND RESULTS: Two analytical methods were employed; viable plate counts…
Novel urethane shape-memory polymers (SMPs) of significant industrial relevance have been synthesized and characterized. Chemically crosslinked SMPs have traditionally been made in a one-step polymerization of monomers and crosslinking agents. However, these new post-polymerization crosslinked SMPs can be processed in…
Magnetic resonance imaging (MRI) has become one of the most important diagnosis tools available in medicine. Typically MRI is not capable of sensing biochemical activities. However, recently emerged activatable MRI contrast agents (CAs), whose relaxivity is variable in response to a specific parameter change in the su…
Using the quasiparticle (QP) self-consistent $\mathit{GW}$ (QS$\mathit{GW}$) and local-density approximations, we calculate the $q$-dependent static dielectric function of undoped graphene and derive an effective two-dimensional (2D) dielectric function corresponding to screening of point charges. In the $q$$\ensurema…
Protein/surface interactions are well known to play an important role in various biological phenomena and to determine the ultimate biofunctionality of a given material once it is in contact with a biological environment. Control over the interactions between proteins and material surfaces are not only of great theore…
We study the electronic structure of diluted F atoms chemisorbed on graphene using density functional theory calculations. We show that the nature of the chemical bonding of a F atom adsorbed on top of a C atom in graphene strongly depends on carrier doping. In neutral samples the F impurities induce a ${\mathit{sp}}^…
We discuss artificial photonic antenna systems that are built by incorporating chromophores into one-dimensional nanochannel materials and by organizing the latter in specific ways. Zeolite L (ZL) is an excellent host for the supramolecular organization of different kinds of molecules and complexes. The range of possi…
