SnO2@TiO2 double-shell nanotubes have been facilely synthesized by atomic layer deposition (ALD) using electrospun PAN nanofibers as templates. The double-shell nanotubes exhibited excellent high rate cyclability for lithium ion batteries. The retention of hollow structures during cycling was demonstrated.
Reconfigurable and tunable frequency selective surfaces (FSSs) are of significant interest in applications such as tunable radomes and adaptive screening of unwanted wireless transmissions. Conventional FSSs require additional bias circuitry to tune the operating frequency or to change its characteristics. In this let…
Nitrogen-doped graphene nanosheets (N-GNSs) displayed a discharge capacity two times greater than their pristine counterpart, as well as superior electrocatalytic activity as a cathode material for sodium-air batteries. The enhanced performance of N-GNSs is attributed to the active sites introduced by nitrogen doping.
We report the template-free synthesis of Ta3N5 nanorod array films grown on Ta foil by a combination of a vapor-phase hydrothermal process and subsequent nitriding. The Ta3N5 nanorod array film modified with Co(OH)x when used as a photoanode in a photoelectrochemical cell for water splitting yields a stable photocurre…
Parkinson's disease is the most common neurodegenerative movement disorder. The motor impairments of Parkinson's disease are caused by the loss of dopaminergic neurons in the substantia nigra and associated with the appearance of fibrillar aggregates of α-synuclein (α-syn) called Lewy bodies. Approximately 90% of α-sy…
A new multifunctional nanovehicle for tumor therapy and cell imaging was fabricated by coating NIR light-responsive polymers (HAMAFA-b-DDACMM) onto the surface of octadecyltrimethoxysilane (C18)-modified hollow mesoporous silica nanoparticles (HMS@C18) via self-assembly. First, the targeting NIR light-responsive block…
Bi2MoO6-RGO composite nanoplates with good uniformity and highly oriented growth of the active lattice were successfully synthesized by a simple hydrothermal process with the assistance of graphene oxide. Reduced graphene oxide was observed to be formed on the surface of the Bi2MoO6 nanoplates after the hydrothermal t…
An Al(3+) selective ratiometric fluorescent probe (L) has been synthesized by condensation of 4,5-diaminopyrimidine with 1-pyrenecarboxaldehyde. The structure of L has been confirmed by single crystal X-ray analysis. In the presence of Al(3+), L exhibits a considerable excimer emission at 445 nm along with the decreas…
Highly-oriented ZIF-8 thin films with controllable thickness were grown on an -OH-functionalized Au substrate using the liquid phase epitaxy method at room temperature, as evidenced by SEM and PXRD. The adsorption-desorption properties of the resulting ZIF-8 thin film were investigated for various VOCs using the QCM t…
Many types of zeolites such as beta (hereinafter, *BEA), CHA, LEV, RUT, and MFI were successfully synthesized by interzeolite conversion of FAU, *BEA, and LEV type zeolites as starting materials under various hydrothermal synthesis conditions. The crystallization rates of zeolites using such starting zeolites were not…
Nanostructured TiO2 possesses unique optical and physical properties as well as exhibiting quantum confinement effects and has attracted much attention in energy conversion and storage research. The energy related applications of nanostructured TiO2 can be grouped into four main categories: lithium-ion batteries, dye-…
Polymeric carbon nitride (g-C3N4) films were synthesized on polycrystalline semiconductor CuInS2 chalcopyrite thin film electrodes by thermal polycondensation and were investigated as photocathodes for the hydrogen evolution reaction (HER) under photoelectrochemical conditions. The composite photocathode materials wer…
The thin films of Cu 2 ZnSnS 4 (CZTS) have been successfully deposited on soda lime glass by spin coating technique. CZTS films were prepared by spin coating of a solution prepared by dissolving of copper (II) chloride, zinc (II) chloride, tin (IV) chloride and Thiourea in 2-Methoxyethanol. The X-ray diffraction studi…
Linear supramolecular polymers were obtained in aqueous solution by employing cucurbit[8]uril-based host-guest interaction as the driving force. Water-soluble monomers were prepared through direct metal-coordination. The rigid and bulky terpyridine-Fe linker can effectively enhance the monomer's solubility and suppres…
Polymers of intrinsic microporosity, e.g. PIM-1, are attractive materials for gas separation and energy development, which is ascribed mainly to their superior permeability. The H2 and CO2 permeability of PIM-1 is about 1300–4000 Barrer and 3000–8000 Barrer, respectively. However, it has a relatively low H2/CO2 select…
In this work, a 21-carbon dicarboxylic acid (C21DA) and a 22-carbon tricarboxylic acid (C22TA) were prepared by the Diels–Alder addition of tung oil fatty acids with acrylic acid and fumaric acid, respectively, and subsequently converted to the corresponding di- and triglycidyl esters. There were no solvents used in t…
Bifunctional Au-loaded Fe3O4@C composite microspheres were controllably synthesized by coating of Au nanoparticles (NPs) on the surface of the poly(diallyldimethylammonium chloride) (PDDA) functionalized Fe3O4@C microspheres. The amount of Au loading can be effectively tuned by altering the feeding amounts of solution…
Zirconium oxide based Metal-Organic Frameworks were synthesised using a rapid and efficient microwave-assisted solvothermal method that produced purer phases and higher quality crystalline products in significantly (>95%) less time than the conventional heating method. A new amino-functionalised analogue has been synt…
Single crystalline SnO2 nanocrystals (~60 nm in size) with a uniform octahedral shape were synthesised using a hydrothermal method. Their phase and morphology were characterized by XRD and FESEM observation. TEM and HRTEM analyses identified that SnO2 octahedral nanocrystals grow along the [001] direction, consisting…
A three dimensional (3D) nanostructured nickel oxide (NiO) electrode was fabricated by an electrodeposition method employing nickel foam (NF) as a scaffold and used for glucose detection. Taking advantage of the synergetic effect of NF and NiO, the 3D NiO/NF electrode shows excellent performance in glucose detection.
