Understanding the bonding trends within, and the differences between, the 4f and 5f element series with soft donor atom ligands will aid elucidation of the fundamental origins of actinide (An) versus lanthanide (Ln) selectivity that is integral to many advanced nuclear fuel cycle separation concepts. One of the princi…
Here we report a covalent bonding approach to fabricate a robust metal-organic framework ZIF-90 coating for solid-phase microextraction. The ZIF-90 bonded fiber exhibits high enhancement factors, wide linearity, excellent reproducibility, and good lifetime for the studied polar endocrine disruptors.
Electrocatalysts for anode or cathode reactions are at the heart of electrochemical energy conversion and storage devices. Molecular design of carbon based nanomaterials may create the next generation electrochemical catalysts for broad applications. Herein, we present the synthesis of a three-dimensional (3D) nanostr…
Poly(amidoamine) modified graphene oxide was prepared via a grafting-from method and characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and atomic force microscopy (AFM). Evaluation of its adsorption capacity for heavy metal ions…
Metal–organic frameworks (MOFs) have attracted interest as adsorbents in water-based adsorption heat pumps owing to their potential for increased water loading capacities and structural and functional tunability versus traditionally used materials such as zeolites and silica. Although pyrazolate-based MOFs exhibit exc…
Gelatin-stabilized copper sulphide nanoparticles with conjugated doxorubicin have been developed for combined photoacoustic imaging, enzyme-responsive drug release and photothermal therapy.
Umbilical cords as a source of stem cells are of increasing interest for cell therapies as they present little ethical consideration and are reported to contain immune privileged cells which may be suitable for allogeneic based therapies. Mesenchymal stem cells (MSCs) sourced from several different cord regions, inclu…
Ag@Pt nanoparticles with various dendritic Pt shells were successfully synthesized by using nonionic surfactants at room temperature. Our recent study demonstrated that the addition of nonionic surfactant plays an important key role in the synthesis of dendritic Pt nanostructures (J. Am. Chem. Soc., 2010, 132, 13636).…
Graphene oxide obtained by the Hummers method was discovered to be an efficient and recyclable acid catalyst for the conversion of fructose-based biopolymers into 5-ethoxymethylfurfural (EMF). EMF yields of 92%, 71%, 34% and 66% were achieved when 5-hydroxymethylfurfural (HMF), fructose, sucrose and inulin were used a…
A facile and scalable step-wise approach has been developed to fabricate graphene-based TiO2/SnO2 hybrid nanosheets (TiO2@SnO2@GN). With uniform staggered distribution of rutile SnO2 and TiO2 nanocrystals in a 2D mesoporous manner, TiO2@SnO2@GN with low content of graphene (∼5 wt%) manifests superior reversible capaci…
Advances in fermentation technologies have resulted in the production of increased yields of proteins of economic, biopharmaceutical, and medicinal importance. Consequently, there is an absolute requirement for the development of rapid, cost-effective methodologies which facilitate the purification of such products in…
A naturally abundant nickel-borate (Ni-Bi) complex is demonstrated to successfully catalyze the photoelectrochemical (PEC) water oxidation of BiVO4 electrodes at 1.23 VRHE with nearly 100% faradaic efficiency for oxygen evolution. Ni-Bi is electrodeposited (ED) and photodeposited (PD) for varying times on BiVO4 electr…
Graphene oxide wrapped gold nanoparticles (Au@NGO) were fabricated by a one-step synthesis. The surface enhanced Raman scattering (SERS) signal from Au@NGO was employed for intracellular Raman imaging in HeLa cancer cells. Anticancer drug doxorubicin was attached onto the nanoparticle surface through noncovalent inter…
Dielectric polymer nanocomposites with high dielectric constant have wide applications in high energy density electronic devices. The introduction of high dielectric constant ceramic nanoparticles into a polymer represents an important route to fabricate nanocomposites with high dielectric constant. However, the nanoc…
This review summarizes the most important advances made in studying mechanochemical activation of latent catalysts (“mechanocatalysis”) over the past few years. First, a historic overview of the development of polymer mechanochemistry is given, followed by a detailed discussion on the physical aspects involved in the…
Strongly adsorbed N atoms inhibit the ammonia decomposition reaction rate. Plasma-driven catalysis can solve this problem and increase the ammonia conversion from 7.8% to 99.9%. (15)NH(3) isotope tracing and optical emission spectroscopy show that gas-phase active species (NH(3)*, NH˙) in the plasma zone facilitate th…
This work provides a facile one-step sol-gel route to synthesize high-quality resorcinol-formaldehyde (RF) resin coated nanocomposites that can be further used to fabricate desired carbon nanostructures. Colloidal particles with different morphologies and sizes can be coated with high-quality RF resin shells by the pr…
As an emerging new polymerization technique, controlled/“living” radical precipitation polymerization (CRPP) involves the introduction of controlled/“living” radical polymerization (CRP) mechanism into the precipitation polymerization system and can be effectively implemented by simply replacing the initiator normally…
