Manganese dioxide exhibits the ideal capacitive behavior in aqueous electrolytes containing alkaline-earth cations ( , , or ). A specific capacitance value as high as was obtained in electrolyte at . The ideal capacitive behavior, high specific capacitance, good coulombic efficiency, and rate ability of manganese diox…
In vitro studies with particles are a major staple of particle toxicology, generally used to investigate mechanisms and better understand the molecular events underlying cellular effects. However, there is ethical and financial pressure in nanotoxicology, the new sub-specialty of particle toxicology, to avoid using an…
Abstract—We review the research progress in reversed Cherenkov radiation in double-negative metamaterials (DNMs) starting from the first experimental verification of the DNMs reported in 2001, including theories, numerical computation and simulation and experiments. We also discuss the potential applications to partic…
Asymmetrical supercapacitors with aqueous electrolytes were fabricated from carbon nanotubes (CNTs) individually coated with and as the negative and positive electrodes, respectively. The nanocomposite is used as the negative electrode material in an asymmetrical supercapacitor. The physicochemical properties of the a…
Molecule-based spin-transportation coexisting systems that exhibit negative giant magnetoresistance and techniques for accessing these molecular systems are introduced as a basis for the construction of molecule-based spintronics.
Zwitterionic hydrogels, including poly(sulfobetaine methacrylate) (polySBMA) and poly(carboxybetaine methacrylate) (polyCBMA), and co-polymeric hydrogels of CBMA and 2-hydroxyethyl methacrylate (HEMA) (poly(CBMA-co-HEMA)) were prepared. Their in vitro and in vivo properties were evaluated and compared with those of po…
Non-spherical silica Janus colloids are prepared by asymmetric wet-etching at the Pickering emulsion interface, and a variety of non-spherical hybrid silica/PS Janus colloids are derived with tunable polymer volume fraction and morphology.
A novel gated photochromic compound Nap-Pip-DTE was prepared to mimic a soft gear-shift based on alternative UV/Vis irradiation, protonation/deprotonation and copper (II) ion complexation/dissociation. The fluorescence and absorption spectra were used as output signals. Copper (II) ion was introduced to mimic the park…
In this paper, we have reported a facile method for the synthesis of ordered magnetic core–manganese oxide shell nanostructures. The process included two steps. First, manganese ferrite nanoparticles were obtained through a solvothermal method. Then, the manganese ferrite nanoparticles were mixed directly with KMnO4 s…
The fluorescence sensing of amine vapor was largely enhanced upon using ultrathin nanofibers, which were fabricated from N-(1-hexylheptyl)perylene-3,4,9,10-tetracarboxyl-3,4-anhydride-9,10-imide by a new self-assembly approach.
Abstract—The design, simulation and fabrication of a left-handed metamaterial (LHM) structure is presented. The combination of the modified square rectangular Split Ring Resonator (SRR) and the Capacitance Loaded Strip (CLS) were used to obtain the negative value of permeability, µ and the negative permittivity, ε. Ni…
Pyrenyl-functionalized distyryl-Bodipy sensitizer attached non-covalently to SWNTs was shown to generate singlet oxygen when excited at 660 nm with a red LED array; this work emphasizes the potential of SWNT as a viable alternative carrier of bioactive agents, including photodynamic therapy sensitizers.
BACKGROUND: The silkworm, Bombyx mori, is an important insect in the textile industry and its pupa are used in Chinese cuisine and traditional Chinese medicine. The silk, urine and dander of silkworms is often the cause of allergies in sericulture workers and the pupa has been found to be a food allergen in China. Rec…
At the onset of dissolution in water, cubic MgO smoke crystals present (110) cuts of the edges of the cubes. Next, (111) facets progressively dominate the shape of the crystallites, which finally transform into truncated octahedra. The morphology of the crystallites that are derived from surface energies computed with…
V2O5 xerogel films were fabricated by casting V2O5 sols onto FTO glass substrates and annealing at 300 °C for 3 hours in nitrogen and air. The films annealed in nitrogen and air possessed different grain size and crystallinity. Optical absorption measurements and electrochemical impedance analyses revealed a reduced o…
Nearly monodisperse alloyed (CuInS2)x(ZnS)1-x nanocrystals with cubic and hexagonal phases were successfully synthesized for the first time, and the band gaps of these alloyed nanocrystals can be tuned in the broad range of 1.5 to 3.7 eV by changing the ratio of CuInS2 to ZnS.
Various types of “intelligent” self-healing anticorrosion coatings using stimuli-responsive behaviour of polyelectrolyte/inhibitor complexes are presented. Flat nanocomposite multilayers as well as colloidally-templated micro- and nanocarriers with incorporated inhibitor are employed as main building blocks for the fo…
A fundamental issue that remains to be solved when approaching the nanoscale is how the size induces transformation among different polymorphic structures. Understanding the size‐induced transformation among the different polymorphic structures is essential for widespread use of nanostructured materials in technologic…
As consumer demands for specific attributes in their textiles increase and global competition intensifies, it is important that the industry finds ways of engineering certain performance requirements into textiles and apparel. This book reviews how fabrics and garments can be engineered to meet technical performance a…
A terbium complex has been designed that may be used to sensitise formation of singlet oxygen (phi(em) 12%), allowing the creation of a ratiometric sensory system for pO(2) (versus the insensitive Eu analogue) and the definition of a reactive probe that can be used to cause local damage to cells loaded with the comple…
