Synthesis and high-throughput testing of multilayered supported ionic liquid catalysts for the conversion of CO 2 and epoxides into cyclic carbonates
Multilayered covalently supported ionic liquid catalysts achieve excellent TON and productivity in the reaction of CO 2 with various epoxides to produce cyclic carbonates.
The pursuit of electrically-driven organic semiconductor lasers
Organic semiconductors have many favourable and plastic-like optical properties that are promising for the development of low energy consuming laser devices. Although optically-pumped organic semiconductor lasers have been demonstrated since the early days of lasers, electrically-driven organic lasers have not been re…
Chitosan-based biopolysaccharide proton conductors for synaptic transistors on paper substrates
The chitosan-based paper synaptic transistors were successfully used as artificial synapses for emulating biological synaptic functions, including excitatory postsynaptic current, paired-pulse facilitation, dynamic filtering and spatiotemporally correlated signal processing.
Polyhedral LiNi 0.5 Mn 1.5 O 4 with excellent electrochemical properties for lithium-ion batteries
Polyhedral LiNi 0.5 Mn 1.5 O 4 exhibiting superior rate and cyclability represents the first experimental evidence for lattice-plane anisotropy.
Highly versatile p(MAc)–M (M: Cu, Co, Ni) microgel composite catalyst for individual and simultaneous catalytic reduction of nitro compounds and dyes
Poly(methacrylic acid) (p(MAc)) microgels were synthesized by inverse suspension polymerization and used as a template for copper, nickel, and cobalt nanoparticle preparation.
Assessing long-range corrected functionals with physically-adjusted range-separated parameters for calculating the polarizability and the second hyperpolarizability of polydiacetylene and polybutatriene chains
The use of physically-adjusted range-separated parameter (μ) together with long-range corrected exchange-correlation functionals is shown not to be reliable for calculating the polarizability (α) and the second hyperpolarizability (γ) of large π-conjugated systems. This statement has been substantiated by calculating…
Microwave Synthesis of Zinc Oxide/Reduced Graphene Oxide Hybrid for Adsorption-Photocatalysis Application
This work reports on synthesis of zinc oxide/reduced graphene oxide (ZnO/rGO) nanocomposites in the presence of diethylenetriamine (DETA) via a facile microwave method. The X-ray diffraction (XRD) patterns of the nanocomposites correspond to the ZnO hexagonal phase wurtzite structure. The high-resolution transmission…
Sortilin mediates the release and transfer of exosomes in concert with two tyrosine kinase receptors
The transfer of exosomes containing both genetic and protein materials is necessary for the control of the cancer cell microenvironment to promote tumor angiogenesis. The nature and function of proteins found in the exosomal cargo, and the mechanism of their action in membrane transport and related signaling events ar…
From ionic-liquid@metal–organic framework composites to heteroatom-decorated large-surface area carbons: superior CO2 and H2 uptake
For the first time, high surface area uniformly nitrogen (N)- and boron-nitrogen (BN)-decorated nanoporous carbons have been successfully fabricated by impregnation of ionic liquids (ILs) within a metal-organic framework (MOF), MIL-100(Al), followed by carbonization, which exhibit remarkable CO2 and H2 adsorption capa…

An optimised scalable synthesis of H 2 O@C 60 and a new synthesis of H 2 @C 60
New high-yielding synthetic routes to the small-molecule endofullerenes H2O@C60, D2O@C60 and H2@C60 are described. The use of high temperatures and pressures for the endohedral molecule incorporation are avoided. A new partial closure step using PPh3, and final suturing using a novel Diels-Alder/retro-Diels-Alder sequ…
Ultrasound-Mediated Local Drug and Gene Delivery Using Nanocarriers
With the development of nanotechnology, nanocarriers have been increasingly used for curative drug/gene delivery. Various nanocarriers are being introduced and assessed, such as polymer nanoparticles, liposomes, and micelles. As a novel theranostic system, nanocarriers hold great promise for ultrasound molecular imagi…
Novel pH switchable gelatin based hydrogel for the controlled delivery of the anti cancer drug 5-fluorouracil
A gelatin based pH responsive composite hydrogel has been synthesised by grafting β-cyclodextrin (β-CD) to gelatin (Gel) and crosslinking with oxidised dextran (OX-Dex). This pH sensitive β-CD grafted Gel crosslinked with OX-Dex (β-CD-g-Gel/OX-Dex) or composite hydrogel (CHG) was used to investigate the colon delivery…
Comparative density functional theory study on the electronic and optical properties of BiMO4 (M = V, Nb, Ta)
By means of density functional theory computations, we investigated the electronic structures and optical properties of BiMO4 (M = V, Nb, Ta) in order to understand their different photocatalytic activities. BiNbO4 and BiTaO4 are direct band gap semiconductors, while BiVO4 has an indirect minimum band gap, and at the…
