A novel, simple and ultra-sensitive method, for rapid detection of trace malachite green (MG) in environmental water using cloud point extraction (CPE) coupled with surface-enhanced Raman scattering (SERS) is described. The colloidal gold nanoparticles (AuNPs) were synthesized by reduction of chloroauric acid (HAuCl4)…
The orientation factor κ(2) ranging from 0 to 4, which depends on the relative orientation of the transition dipoles of the energy donor (D) and the energy acceptor (A) in space, is one of the pivotal factors deciding the efficiency and directionality of resonance energy transfer (RET) in a D-A molecular system. In th…
New core–shell nanoparticles were synthesized by grafting a poly(acrylate amide) shell onto a cross-linked polystyrene nanoparticle (NP) via atom transfer radical polymerization (ATRP). The core–shell NPs self assemble into self-healing materials in which the dynamic hydrogen-bonding shell confers self-healing propert…
CeO(2) has been identified as an efficient catalyst for HCl oxidation in the temperature range of 623-723 K provided that the oxygen content in the feed mixture was sufficiently high to avoid bulk chlorination and thus deactivation. Here we characterise ceria in its fresh and post-reaction states by adsorption of CO(2…
A V-shaped cyanostilbene amide derivative (BPBIA) containing tert-butyl groups has been designed and synthesized. It was employed as building blocks to fabricate one-dimensional (1D) organic nano- or microstructures. BPBIA shows excellent self-assembling properties. First, it can readily self-assemble into gels with n…
Large area thin films of few-layered unfunctionalized graphene platelets are developed with fine control over the thickness. The thin films are obtained by a Langmuir-Blodgett assembly at the interface of graphene solution in N-methyl-2-pyrrolidone (NMP) and water, and their optoelectronic properties and conduction me…
A comprehensive investigation of the mechanical behavior and microstructural evolution of carbon nanotube (CNT) continuous fibers under twisting and tension is conducted using coarse-grained molecular dynamics simulations. The tensile strength of CNT fibers with random CNT stacking is found to be higher than that of f…
SnO2-CuO composite nanorods with a Janus structure were prepared by one-step flame spray pyrolysis. High-aspect-ratio SnO2 nanorods were positioned on one side of the spherical CuO powder. The mean length of the rod-shaped crystals decreased from 200 to 20 nm when the SnO2 content in the composite powders decreased fr…
The widely accepted approach for controlling polymer debonding/rebonding properties in responsive materials has been to purposefully engineer the functional end-groups responsible for monomer dynamic bonding. Here, however, we evidence that the debonding temperature of a polymer can also be tuned by changing the chain…
A simple and efficient method to prepare halogenated carbon quantum dots (CQDs) through solvent-thermal reaction was reported. The halogenated CQDs were synthesized and further surface functionalization with diamines was achieved based on the halogenated CQDs as intermediates. The halogenated CQDs provide an alternati…
Here, an oil-in-water emulsion method was used to assemble monodisperse noble metallic nanoparticles (NPs) in the oil phase into aggregates in the aqueous phase. The original size of the NPs is an essential factor in determining the final morphology: beyond the critical size, spherical aggregates with the original NPs…
Ferroelectric (FE) and ferromagnetic (FM) materials engineered in horizontal heterostructures allow interface-mediated magnetoelectric coupling. The so-called converse magnetoelectric effect (CME) has been already demonstrated by electric-field poling of the ferroelectric layers and subsequent modification of the magn…
Lanthanide dinuclear complexes involving tetrathiafulvalene-based ligands in their radical cation form were synthesised and crystallised by a galvanostatic procedure. Dynamic magnetic measurements reveal an unprecedented slow magnetic relaxation for the Dy(III) analogue in this kind of molecular edifice.
Understanding dynamic changes of catalytically active nanostructures under reaction conditions is a pivotal challenge in catalysis research, which has been extensively addressed in metal nanoparticles but is less explored in supported oxide nanocatalysts. Here, structural changes of iron oxide (FeO(x)) nanostructures…
Compared with the bulk, one-dimensional (1D) nanostructural materials exhibit enhanced thermoelectric performance. The figures of merit for most bulk materials used in practical devices are close to 1. However, the values for 1D nanostructural materials have reached 2.5 from experiments and could exceed 10 from theore…
SBA-16 silica with intact surface hydroxyl groups was quickly obtained (5 min) via a fast-microwave-assisted method, and further adopted as an efficient template for the synthesis of three-dimensional (3D) ordered mesoporous CuOx–CeO2 catalysts (htpCCx) through a simple and reproducible host–guest interaction. XRD, XP…
A mechanochemically driven solid-state Diels–Alder reaction is demonstrated via dry ball-milling graphite as the diene in the presence of maleic anhydride or maleimide as the dienophile. On the basis of various characterizations, the Diels–Alder adducts are edge-selectively functionalized and subsequently delaminated…
Investigations into the interaction between molecular hydrogen and molybdenum disulphide have been in increasing demand to improve the understanding of the hydrodesulphurisation process, especially the creation of sulphur vacancies which result in coordinatively unsaturated sites in MoS2. Here we present comprehensive…
Recent advances in nanotechnology have permitted the development of a wide repertoire of inorganic magnetic nanoparticles (NPs) with extensive promise for biomedical applications. Despite this remarkable potential, many questions still arise concerning the biocompatible nature of NPs when in contact with biological sy…
Nanotechnology in Agroecosystem: Implications on Plant Productivity and its Soil Environment Compared to conventional or other contaminants, nanoparticles pose some new environmental challenges for scientists and environmentalists worldwide. Nanotechnology will leave no field untouched including agriculture by its gro…
