A white-light-emitting Eu( iii ) coordination polymer based on a 1,8-naphthalimide-derivative was synthesized, and three primary colours are well balanced by controlling energy transfer efficiency from fluorophore to Eu( iii ) ions.
ZnO ultrathin films with varied thicknesses of 7-70 nm were prepared at 200 °C on Si and fused quartz substrates by atomic layer deposition (ALD). The impact of film thickness and annealing temperature on the crystallinity, morphology, optical bandgap, and photocatalytic properties of ZnO in the degradation of methyle…
We report the green electrochemical synthesis of size-controlled AgNPs by tuning the flow velocity in a continuous flow system, and an improved multi-electrode design for increasing the synthesis yield in unit time.
In several experimental studies, room temperature ferromagnetism in Gd-doped ZnO nanostructures has been achieved. However, the mechanism and the origin of the ferromagnetism remain controversial. We investigate the structural, magnetic, and electronic properties of Zn48O48 nanowires doped with Gd, using density funct…
A yellow-orange emitting garnet phosphor Mg 2 Y 2 Al 2 Si 2 O 12 :Ce 3+ was prepared through combination substitution, and a high colour rendering index white LED lamp was achieved.
Gold nanoparticles (AuNPs) have demonstrated increasingly wide applications in drug delivery due to their unique physicochemical and optical properties as well as low toxicity. Compared to the organic nanocarriers for therapeutic agents, AuNPs have shown superior performance as drug delivery vectors, including the ine…
A dynamic covalent crosslinking approach is used to crosslink supramolecular peptide gels. This novel approach facilitates tuning viscoelastic properties of the gel and enhances mechanical stability (storage modulus exceeding 10(5) Pa) of the peptide gels.
We investigated the dependence of the surface-enhanced Raman scattering (SERS) activity of densely arranged two-dimensional assemblies of spherical Au(core)-Ag(shell) nanoparticles (Au/AgNSs) on the nanoparticle diameter. The size-controlled Au/AgNSs were synthesized using the Au nanosphere seed-mediated growth method…
Innovative carbon coating on nano-porous anodic aluminum oxide templates enables coatings on dense self-supported nanostructured arrays in a reverse manner for applications in energy devices ( e.g. , supercapacitors).
A novel luminescence probe based on mono-6-amino-β-cyclodextrin (NH2-β-CD) functionalised gold nanoclusters (β-CD-AuNC) was designed for dopamine (DA) detection. The NH2-β-CD molecules were conjugated onto the surface of 11-mercaptoundecanoic acid capped AuNCs (11-MUA-AuNC) via a carbodiimide coupling reaction. The in…
In a size regime where every atom counts, rational design and synthesis of optimal nanostructures demands direct interrogation of the effects of structural divergence of individuals on the ensemble-averaged property. To this end, we have explored the structure-function relationship of single quantum dots (QDs) via pre…
In this study, to approach the scalable fabrication of super-hemocompatible and antibacterial membranes, surface engineered 3D heparin-mimicking coatings were designed by layer by layer (LBL) assembly of water-soluble heparin-mimicking polymer (WHP) and quaternized chitosan (QC). The low cost and scalable WHP was synt…
The fabrics used for active sportswear are specially constructed in terms of the geometry, packing density and structure of the constituent fibres in yarn as well as their construction in order to achieve the necessary dissipation of heat and moisture. Performance of player can be enhanced by specialised sportswear li…
An alternative and facile strategy to fabricate conducting reduced graphene oxide/polyaniline (rGO/PANI) hybrid composites with highly enhanced thermoelectric properties is introduced. rGO and PANI were homogeneously mixed by cryogenic grinding.
V 1−x W x O 2 (M/R) nanorods with superior doping efficiency (103 °C per at% W) and thermochromic property ( T vis = 60.6%, Δ T sol = 10.3%) were synthesized using a one-step hydrothermal method.
Maintaining the long-term stability of superhydrophobic surfaces is challenging because of contamination from organic molecules and proteins that render the surface hydrophilic. Reactive oxygen species generated on a photocatalyst, such as TiO2, could mitigate this effect by oxidizing these contaminants. However, inco…
The ultimate scaling limit and device physics of aggressively scaled phosphorene MOSFETs are examined by self-consistent multiscale quantum transport simulations. The MOSFET structure can effectively suppress the ambipolar conduction and decrease the leakage current, and thereby, is more scalable than the Schottky bar…
In this study, we report high catalytic activity for acetylene hydrochlorination by post-treatment of active carbon (AC) with polyaniline (PANI) followed by pyrolyzation at high temperature.
The catalytic properties of the single-Pd-doped Cu 55 nanoparticle toward propane dehydrogenation have been systemically investigated by first-principles calculations, and the possible reaction mechanisms and effects of the single and multiple Pd doping on the catalytic activity have been discussed. Calculations revea…
This paper presents the Hencky bar-chain model (HBM) for buckling and vibration analyses of Euler–Bernoulli beams with elastic end restraints. The Hencky bar-chain comprises rigid beam segments (of length a = L/n where L is the total length of beam and n the number of beam segments) connected by frictionless hinges wi…
