ions, the probe displayed apparent fluorescence changes from non-emission to strong green fluorescence. C1 gave response to hydrogen sulfite with high sensitivity and the detection limit was determined to be as low as 3.0 μM. In addition to its high selectivity for hydrogen sulfite rather than other common anions, C1…
A facile and straightforward approach is developed for the construction of graphene-based hollow spheres. An electron rich sodium-ammonia solution is used to effectively restore the π-conjugation of graphene. The hollow spheres exhibit excellent electrocatalytic activity towards oxygen reduction without catalyst deact…
Tailorable synthesis of plasmon enhanced catalysts with high solar-light harvesting and energy-conversion efficiency has attracted wide interest due to its scientific and technological importance. In this paper, novel SiO2–Ag–SiO2–TiO2 multi-shell photocatalysts with wide-spectral-response were systematically designed…
Solid-state combinatorial chemistry (combi-chem) has been proven to be a versatile tool for the discovery of novel phosphors in the multi-compositional (oxy)nitride search space. Since the advent of a unique solid-state combi-chem technique involving heuristic optimization strategies such as a non-dominated sorting ge…
Americanae nace como un proyecto conjunto que surge dentro de la Red Europea de Información y Documentación sobre América Latina (REDIAL), y que ha afrontado la Biblioteca de la Agencia Española de Cooperación Internacional para el Desarrollo (AECID). Esta nueva biblioteca virtual hace más accesibles los libros digita…
Performance of thin film photovoltaics largely relies on photon absorption capability. Here, we introduce a novel substrate with patterned aluminum nanodent arrays with unique light management capability. Hydrogenated amorphous silicon thin film solar cells have been fabricated on the nano-texturized substrate for opt…
Four porous heterometallic coordination polymers were synthesized via a metalloligand strategy. All of them contain the [Pd(diimine)Cl(2)] moiety, which has good catalytic activity, and present remarkable versatility for catalysing Suzuki-Miyaura and Heck reactions.
Five protective garments (light summer clothing L, high visibility clothing HV, military clothing MIL, climber coverall CLM and firefighting clothing FIRE) were assessed on eight unacclimated male subjects at two environments: moderate warm environment with high humidity (MWH, 20.0°C, 86% relative humidity) and warm e…
Passerini three-component reaction and multicomponent polymerization (MCP) were demonstrated to be facile methods for the preparation of photo-cleavable polymers, photo- and redox-dually cleavable polymers, as well as block copolymers.
Highly sensitive and selective NO2 sensing performances were realized with the networked SnO2 microrods functionalized with Ag nanoparticles by applying γ-ray radiolysis. The Ag nanoparticles were transformed into nanoparticles of the Ag/Ag2O phase by thermal heating. The NO2 sensing characteristics of the Ag-function…
We report new solution processable electron transport layers for organic photovoltaic devices based on composites of metal oxides and reduced graphene oxides. Low bandgap polymer cells fabricated using these nanohybrid transport layers display power conversion efficiencies in the range of 7.4–7.5% which is observed to…
Due to the chemical stability and easy fabrication by atomic layer deposition (ALD), TiO2 nanotubes are regarded highly useful in constructing branched nanostructured electrodes for solar conversion and electrochemical energy storage devices. Here we present a facile and scalable fabrication of metal oxide nanobranche…
A polymer analogous reaction was carried out to generate a porous polymeric network with N-heterocyclic carbenes (NHC) in the polymer backbone. Using a stepwise approach, first a polyimine network is formed by polymerization of the tetrafunctional amine tetrakis(4-aminophenyl)methane. This polyimine network is convert…
In order to enrich the variety of zinc oxide (ZnO), well-defined ZnO hollow microspheres self-assembled by a mass of nanoparticles were successfully synthesized through a facile solvothermal process employing polyethylene glycol 400 (PEG 400) as the solvent. PEG 400 played a crucial role as a nonionic surfactant in th…
Hypochlorite is one of the biologically important reactive oxygen species (ROS). Herein, a BODIPY-based fluorescent probe (BOD-OXIME) has been designed and synthesized for fluorescence detection of hypochlorite in aqueous media and imaging in live cells. Incorporating hydrophilic carboxyl and hydroxyl moieties makes t…
The direct hydroamination of alkynes driven by visible light can be achieved in high yield and selectivity at ambient temperature using supported gold nanoparticles (AuNPs) as photocatalysts. Aniline molecules interact with visible light activated AuNPs meanwhile alkynes could be activated at active sites on the suppo…
An ICT-based fluorescent turn-on probe for hydrogen sulfide with high selectivity has been designed and synthesized. It exhibits up to 62-fold switch-on response toward H2S at given concentrations and can detect H2S in living cells with high sensitivity.
Co3O4/onion-like carbon (OLC) nanocomposites with a high surface area of 222.83 m2 g−1 were synthesized by a simple solvothermal method for application as an anode material in lithium ion batteries (LIBs). The electrochemical properties of the hybrid nanocomposites were investigated by a half-cell LIB configuration wi…
Bi2WO6 superstructures have attracted extensive attention in the photocatalytic field, but their practical application has been limited by drawbacks such as an unsatisfactory visible-light photoresponse range. To address these drawbacks, we have developed a simple strategy by surface decoration of Bi2WO6 superstructur…
BACKGROUND: Carbon nanotubes (CNT) can induce lung inflammation and fibrosis in rodents. Several studies have identified the capacity of CNT to stimulate the proliferation of fibroblasts. We developed and validated experimentally here a simple and rapid in vitro assay to evaluate the capacity of a nanomaterial to exer…
