The nanoparticles of CaMoO(4) : Eu(3+) (Eu(3+) = 0, 1, 3, 5, 7, 10 at. %) are prepared at low temperature (150 °C for 3 h) using urea hydrolysis in ethylene glycol. These are characterized by X-ray diffraction (XRD), infrared spectroscopy (IR) and transmission electron microscopy (TEM). From XRD study, it was found th…
A biocompatible, seed-mediated synthesis of monodisperse ~60 nm gold nanostars, followed by hydrophilic stabilization with ethylene glycol-modified Raman reporter molecules, is presented. Their application as SERS labels for imaging of the tumor suppressor p63 in prostate biopsies by immuno-SERS microscopy is demonstr…
Stretchable conductive polymers have aroused extensive interest in research recently due to their hi-tech applications in the fields of novel electronics, particularly for flexible electronic displays, smart textiles, medical electronics, sensors and actuators. In this study, we describe a novel elastic conductive nan…
A new type of magnetically-recoverable catalyst was synthesized by the immobilization of H3PW12O40 on the surface of silica-encapsulated γ-Fe2O3 nanoparticles. This catalyst was characterized by transmission electron microscopy (TEM), a laser particle size analyzer, infrared spectroscopy (IR) and inductively coupled p…
Novel ZnO/TiO(2) composite nanofibers were fabricated by an electrospinning method and showed excellent antimicrobial activity against gram-negative Escherichia coli and gram-positive Staphylococcus aureus under UV irradiation and in the absence of light.
Nanopaper from wood-based nanofibrillated cellulose (NFC) offers vastly improved strength and strain-to-failure compared with plant fiber-based paper and plant fiber biocomposites. In the present study, unique nanostructural toughening effects are reported in cellulose nanofiber/hydroxyethylcellulose (HEC) biocomposit…
A Dy(2) single-molecule magnet was isolated using a mixed ligand strategy in which the Dy(III) ions adopt distinct coordination environments. This leads to two unique relaxation modes due to a single-ion type relaxation mechanism. Energy barriers were obtained from individually fitting the overlapping peaks.
In the supercooled regime at elevated pressure two forms of liquid water, high-density (HDL) and low-density (LDL), have been proposed to be separated by a coexistence line ending at a critical point, but a connection to water at ambient conditions has been lacking. Here we perform large-scale molecular dynamics simul…
Hydrolytic degradations of polylactic acid/rice hulls (PLA/RH) composites with various rice hulls contents due to water absorptions at 23, 51 and 69C were investigated by studying the thermal properties, chemical composition, molecular weight, and morphology of the degraded products. The results have attested that the…
We introduce chemical structures and reactivity of oxygen-centred radicals (O(-)˙) over transition metal oxide (TMO) clusters based on mass spectrometric and density functional theory studies. Two main issues will be discussed: (1) the compositions of TMO clusters that have the bonding characteristics of (or contain)…
Eu3+ doped red-emitting phosphors of double phosphates Ca9R(PO4)7 (R = Al, Lu) were synthesized by a general high temperature solid-state reaction. The phosphors were characterized by X-ray powder diffraction (XRD). The detailed luminescence properties, e.g., the emission spectra under the excitation of UV light, the…
We report the structural evolution and the diffusion processes which occur during the phase transformation of nanoparticles (NPs), ε-Co to Co2P to CoP, from a reaction with tri-n-octylphosphine (TOP). Extended X-ray absorption fine structure (EXAFS) investigations were used to elucidate the changes in the local struct…
Adhesion and excessive accumulation of atmospheric ice on the surface of exposed objects such as conductors of overhead power lines, cables and conductors in aluminum can have devastating economical and safety consequences as it was the case during the 1998 and 2007 ice storms in Canada and USA. Recent advances in the…
Peptide nanotubes are promising bio-inspired self-assemblies with a wide range of envisioned applications. The present review addresses the recent advances in their fundamental comprehension and mechanistic aspects of their latest downstream uses. Through well-documented examples, including the Lanreotide peptide mono…
Over the past five years, the use of pair distribution function (PDF) methods to study local structure has become increasingly prominent in the mainstream materials chemistry literature. Because the technique is sensitive not only to the average (long-range) material structure but also to any local distortions away fr…
Yellow-to-red emitting CuInS2/ZnS (CIS/ZnS) core/shell quantum dots (QDs) with a maximum photoluminescence quantum yield (QY) of ∼65% were facilely synthesized via a stepwise, consecutive solvothermal approach. The size-sorting experiments on CIS/ZnS QDs indicated that the ZnS shell was formed with a relatively unifor…
Single-crystalline hexagonal prism Zn(2)GeO(4) nanorods with different aspect ratios have been prepared via a solution phase route, which exhibits improved photocatalytic activities in overall water splitting and photoreduction of CO(2) due to the low crystal defects, high specific surface area and beneficial microstr…
Porous sulfur-doped carbon was synthesised by using a thienyl-based polymer network as a precursor. The sulfur amount varies from 5-23 m% while the materials show microporosity with BET surface areas of up to 711 m(2) g(-1).
Mesoporous carbon nitrides (MCN) were prepared by a nano-casting method using mesoporous silica as a template with different carbon and nitrogen sources like melamine only (MS-MCN), urea-formaldehyde (UF-MCN) and melamine-glyoxal (MG-MCN). These mesoporous carbon nitride materials possess nitrogen moieties which behav…
Wires and cables are essential to modern society, and opportunities exist to develop new materials with reduced resistance, mass, and/or susceptibility to fatigue. This article describes how carbon nanotubes (CNTs) offer opportunities for integration into wires and cables for both power and data transmission due to th…
