Catalyzing the carbonization of a polymer itself to form a protective carbonaceous layer has attracted tremendous interest in the flame retardancy of polymers, but the efficiency of this strategy was largely limited to polymers containing heteroatoms within their backbone. In this study, a novel type of combined catal…
We present an environmentally benign, energy efficient and readily scalable approach to synthesize photoluminescent carbogenic nanoparticles directly from soft tissue biomass. Our approach relies on the pyrolytic decomposition of grass that gives rise to the formation of well-defined nanoparticles. The carbogenic nano…
The reaction between 1,3,5-tris(4-hydroxyphenyl)benzene and benzene-1,3,5-tricarbonyl trichloride leads to polyester condensation and formation of a novel COF on an Au(111) surface. The characterization performed in situ by means of variable temperature STM and XPS reveals the formation of an array of hexagonal caviti…
Conducting polymer polypyrrole (PPy) was revisited as cathode material for lithium-ion battery. Synthesis condition, microstructure, doping effect and electrochemical performance were systematically investigated. Chemical polymerization was employed to synthesize PPy with sodium p-toluenesulfonate (pTSNa) as anionic d…
A template-free solvothermal combined with precursor thermal transformation method has been developed for the preparation of flower-like Fe3O4 nanostructured hollow microspheres. The reaction mechanism and the self-assembly evolution process were studied, and it was found that the synthetic conditions for the precurso…
The green natural compounds, tea polyphenols (TP), were introduced to synthesize well-dispersed Au nanoparticles (AuNPs) in polyacrylonitrile (PAN) nanofibers by combining an in situ reduction approach and electrospinning technique. The AuNPs were firstly synthesized in aqueous solution to test the reducibility of the…
A novel dodeca-ligated undecagold cluster having a nonagold core plus two exo-attached gold atoms was synthesized. Unlike the conventional icosahedron-based "core-only" isomer, the [9+2] cluster showed an intense visible absorption band. Theoretical calculation showed the involvement of the exo gold atoms in the gener…
We describe a facile room temperature solution-phase chemical approach for large scale synthesis of sub-15 nm ultralong crystalline CuO nanowires with an average diameter of about 8 nm and lengths of up to several tens of micrometers. The results indicated that Cu(OH)2 nanowires were first formed and subsequently serv…
ZnO nanodisks consisting of nanocrystallines were successfully synthesized via a simple chemical hydrolysis method in the dimethyl sulfoxide (DMSO)–H2O system. The growth mechanism of the nanodisks were studied by time-dependent experiments, and the morphology of these nanodisks could be readily tuned by simply adjust…
Dissipative particle dynamics (DPD) simulations were performed to study the stability of Pickering emulsions. Two droplets covered by nanoparticles were forced to coalesce. The simulated experiment was systematically repeated for a number of conditions. Decane droplets in water as well as water droplets in decane were…
A novel switchgrass (Panicum virgatum) extract mediated green process was demonstrated for the synthesis of silver nanoparticles from silver nitrate solution at ambient temperature. UV-visible spectroscopic analysis indicates the rapid reduction of silver (Ag+) ions by swithgrass extract. The silver nanoparticles bega…
Improved positively charged nanoparticles are described to provide a simplified SERS substrate for DNA detection. Complete flocculation of the nanoparticles is prevented due to the controlled analyte induced aggregation. This provides a stable aggregation state which significantly extends the analysis window simplifyi…
Conventional methods of environmental analysis can be significantly improved by the development of portable microscale technologies for direct in-field sensing at remote locations. This report demonstrates the vast potential of gold nanoparticle-based microfluidic sensors for the rapid, in-field, detection of two impo…
Nephrogenic Systemic Fibrosis is a rare condition appearing only in patients with severe renal impairment or failure and presents with dermal lesions and involvement of internal organs. Although many cases are mild, an estimated 5% have a progressive debilitating course. To date, there is no known effective treatment…
The excitation spectra of linear atomic chains of silver and gold with various sizes have been calculated using time-dependent density functional theory. Silver chains show longitudinal and transverse peaks as well as a low-intensity d-band. The longitudinal peak, corresponding to the HOMO-LUMO transition (along the m…
Controlling the electrical transport properties of II–VI nanostructures is vital to their practical applications. Here, we report the synthesis of n-type ZnS nanowires (NWs) by using aluminium (Al) as a dopant via a simple thermal co-evaporation method. The conductivities of the ZnS:Al NWs were greatly enhanced upon A…
In this article, we present a new, facile and efficient electrochemical method for the production of a stable aqueous dispersion of a graphene–metal phthalocyanine hybrid material. The material has been prepared by electrolytic exfoliation of graphite in an electrolyte containing copper phthalocyanine-3,4′,4′′,4′′′-te…
An air-stable photoresponsive viologen molecular system is constructed based on a three-fold accordion interpenetrating packing arrangement. The fluorescent modulation process is coupled with a photochromic reaction via energy and electron transfer between the adjacent donor and acceptor groups.
An indium trimesate metal–organic framework (JUC-120) which possesses a cubic zeolitic MTN topology, as a new analogue to MIL-100(Al, Fe or Cr) compounds, has been successfully synthesized. Its structure exhibits a mesoporous cage (26 Å) and high thermal stability. The assembly of nitrobenzospiropyran derivatives (BSP…
BACKGROUND: A critical disadvantage for successful chemotherapy with paclitaxel (PTX) is its nontargeting nature to cancer cells. Folic acid has been employed as a targeting ligand of various anticancer agents to increase their cellular uptake within target cells since the folate receptor is overexpressed on the surfa…
