Recently a new form of ultra-thin flexible waveguide consisting of a conducting comb-like structure with a thickness of the order of 1/600(th) of the operating wavelength was presented. However, whilst the thickness of the guide was massively sub-wavelength, the remaining dimensions (the height and period of the comb)…
Abstract Ceria nanoparticles (nanoceria) are well known as a superoxide scavenger. However, inherent superoxide‐scavenging ability has only been found in the nanoceria with sizes of less than 5 nm and with very limited shape diversity. Reported herein is a strategy to significantly improve the superoxide‐scavenging ac…
X-ray structural analysis, together with steady-state and transient optical spectroscopy, is used for studying the morphology and optical properties of quantum dot superlattices (QDSLs) formed on glass substrates by the self-organization of PbS quantum dots with a variety of surface ligands. The diameter of the PbS QD…
Covalently linked donor–acceptor dyads involving palladium(II) and platinum(II) porphyrins as triplet sensitizers and fullerene as an acceptor have been newly synthesized. These dyads were characterized by optical absorbance, emission, and electrochemical methods. In contrast to the earlier reported zinc(II) porphyrin…
We describe a simple and general approach to conjugate nanoparticles on pristine graphene. The method takes advantage of the high reactivity of perfluorophenyl nitrene towards the C[double bond, length as m-dash]C bonds in graphene, where perfluorophenyl azide-functionalized nanoparticles are conjugated to pristine gr…
Skin loss is one of the oldest and still not totally resolved problems in the medical field. Since spontaneous healing of the dermal defects would not occur, the regeneration of full thickness of skin requires skin substitutes. Tissue engineering constructs would provide a three dimensional matrix for the reconstructi…
Based on a recent experimental study on the Ni3 C12 S12 sheet [J. Am. Chem. Soc. 2013, 135, 2462] and a theoretical study on the Mn3 C12 S12 sheet [Nanoscale- 2013, 5, 10404], by using density functional theory combined with a thermodynamic model, it is shown that when sulfur atoms are replaced by NH groups the resu…
Abstract Hydrothermal crystal growth can be described as a low temperature process under pressure using an aqueous solution as the solvent. The temperature gradient controls the transport phenomenon from the nutrient to the seeds. The solvothermal term is generally used when the solvent is a non‐aqueous solution. Diff…
The influence of solid-liquid adhesive property on liquid slippage at solid surfaces has been investigated using experiment approach on well-defined model surfaces as well as theoretical analysis. Based on a classical molecular-kinetic description for molecular and hydrodynamic slip, we propose a simple theoretical mo…
Perfectly defined, monodisperse fusion protein block copolymers of a thermoresponsive coil‐like protein, ELP, and a globular protein, mCherry, are demonstrated to act as fully biosynthetic analogues to protein‐polymer conjugates that can self‐assemble into biofunctional nanostructures such as hexagonal and lamellar ph…
Three halogen-free, phosphorus-based flame retardant monomers were synthesized with good yields and characterized using FT-IR, 1 H NMR, and 31 P NMR. Two of the monomers were novel phosphoramides and the third was derived from cyclotriphosphazene. Each monomer was coated onto cotton substrates with the aid of a UV flo…
Crown-jewel-structured (IrPd)/Au trimetallic nanoclusters are prepared by a galvanic replacement reaction using Ir/Pd nanoclusters with a structure of Ir rich in the core and Pd rich in the shell as mother clusters. The catalytic activity of the top Au atoms for aerobic glucose oxidation of the trimetallic nanocluster…
INTRODUCTION: The increase in the development of novel nanoparticle drug delivery systems makes the choice between micro- and nanoscale drug delivery systems ubiquitous. Changes in physical and chemical properties between micro- to nanosized particles give them different properties that influence their physiological,…
In this paper, magnetic core–shell nanoflower Fe 3 O 4 @MnO 2 were fabricated via a solvothermal method.
A simple and inexpensive chemical bath deposition method was employed for the preparation of lead sulfide (PbS) thin films.
Urchin-like hollow boehmite and alumina microspheres were fabricated via Triton X-100 assisted hydrothermal synthesis.
Hexagonal boron nitride (h-BN) is often prepared by epitaxial growth on metals, and stability of the formed BN/metal interfaces in gaseous environment is a key issue for physicochemical properties of the BN overlayers. As an illustration here, the structural change of a BN/Ru(0001) interface upon exposure to O2 has be…
The characteristics of the gate electrode have significant effects on the behavior of organic electrochemical transistors (OECTs), which are intensively investigated for applications in the booming field of organic bioelectronics. In this work, high specific surface area activated carbon (AC) was used as gate electrod…
Here, we demonstrate novel carbon-nitrogen quantum dots (CNQDs) by the hydrothermal method using melamine and glutaraldehyde. CNQDs are uniformly dispersed with particle diameters of 3-8 nm. These prepared CNQDs show excellent luminescence properties and the photoluminescent quantum yields of CNQDs with 365 nm emissio…
Activated carbon (AC) was produced via phosphoric acid (H3PO4) and zinc chloride (ZnCl2) chemical activation methods at 500 °C for 3 h. Tropical peat soil was used as a carbon precursor. The effects of activating agent concentrations on the microstructure and chemical properties of activated carbon were studied. Activ…
