We report here a facile approach for flexible integration of high efficiency surface enhanced Raman scattering (SERS) monitors in a continuous microfluidic channel. In our work, femtosecond laser direct writing was adopted for highly localizable and controllable fabrication of the SERS monitor through a multi-photon a…
An effective single-walled carbon nanotube (SWNT) covalently loaded with unsaturated terbium emissive material was designed for specific and rapid (2-3 s) detection of calcium dipicolinate (CaDPA) (detection limit 1 μM). The nanoprobe was successfully assembled onto electrodes and its sensing abilities were investigat…
We perform a spin polarized density-functional theory (DFT) study of the electronic and magnetic properties of pristine and chemically doped germanene nanoribbons (GeNRs) with different widths. It is found that the Ge atom at the ribbon edge always prefers to be substituted by an impurity atom. Our study reveals that…
Two heterometallic [DyIII6MnIII12] clusters comprising of the same [MnIII8O13] fragment, four isolated MnIII ions and two linear [DyIII3] units have been synthesised. Except for the same composition, the main difference of these two cores lies in the coordination environment and the orientations of the linear [DyIII3]…
An oriented attachment and growth mechanism allows an accurate control of the size and morphology of Cu(2-x)S nanocrystals, from spheres and disks to tetradecahedrons and dodecahedrons. The synthesis conditions and the growth mechanism are detailed here.
Novel rare earth based 4,4′,4′′-benzene-1,3,5-triyl-tri-benzonate (RE-BTB) infinite coordination polymer (ICP) hollow microspheres have been successfully prepared via a facile surfactant-free mixed-solvothermal route, among which Tb-BTB was studied in detail. These as-prepared hollow microspheres using terbium as the…
A series of polyphosphoramides with high char residues were successfully synthesized using solution polycondensation and well characterized. The thermal properties and flammability were investigated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and microscale combustion calorimeter (MCC)…
Flexible graphene sheet (GS)/polyaniline (PANi) nanofibers composite paper was prepared via a facile and fast two-step route composed of electrostatic adsorption between negatively-charged poly(sodium 4-styrenesulfonate) (PSS) mediated GS (coded as PSS-GS) and positively-charged PANi nanofibers and the follow-up vacuum…
Membrane filtration is an attractive approach for soluble catalyst recycling. Applications of nanofiltration have demonstrated their great potential as a method for process intensification in enzyme, organo-, and homogeneous catalysis, both in laboratory practice and on an industrial scale. Selected, recent advances i…
In this paper we report on the one-pot transformation of glycerol into acrylic acid, catalyzed by W/V mixed oxides, with hexagonal tungsten bronze (HTB) structure. The reaction requires two different catalyst functions, i.e., an acid one, which is given by W oxide, and an oxidizing one, given by the V ions incorporate…
Selective disposition of nanocarriers into target tissue is an essential issue in drug delivery. Critical size of nanocarriers (∼150 nm) discriminating the permeability into normal and tumor tissues was determined by the use of size-tunable, polyion complex hollow vesicles (PICsome) as a ruler.
The electronic structure and magnetic properties of the graphene/Fe/Ni(111) system were investigated via combination of the density functional theory calculations and electron-spectroscopy methods. This system was prepared via intercalation of thin Fe layers (1 ML) underneath graphene on Ni(111) and its inert properti…
The interactions of proteins with the surface of cylindrical nanopores are systematically investigated to elucidate how surface curvature and surface chemistry affect the conformation and activity of confined proteins in an aqueous, buffered environment. Two globular proteins, lysozyme and myoglobin, with different ca…
Electrospinning is a simple and highly versatile method for generating ultrathin fibres with diameters ranging from a few micrometres to tens of nanometres. Although most commonly associated with textile manufacturing, recent research has proved that the electrospinning technology can be used to create organ component…
The ability to compare bovine and porcine skin gelatin based on their amino acid composition, polypeptides pattern, bloom strength, turbidity and foaming properties were investigated. Amino acid composition of both gelatin showed that the content of glycine, proline and arginine in porcine gelatin were higher than bov…
During the last decade, significant scientific research efforts have led to a significant growth in understanding of cancer at the genetic, molecular, and cellular levels providing great opportunities for diagnosis and treatment of cancer diseases. The hopes for fast cancer diagnosis and treatment were significantly i…
A new strategy of synthesizing hexagonal upconversion NaYF(4) at low temperature (down to 130 °C) based on Ti(4+) doping-induced cubic-to-hexagonal phase transition in a liquid-solid-solution reaction system is offered.
In this study, a systematic series of AuPd bimetallic particles were prepared by colloidal synthesis methods, in order to gain better control over the particle size distribution and structure. Particles having random alloy structures, as well as 'designer' particles with Pd-shell/Au-core and Au-shell/Pd-core morpholog…
α-Zirconium phosphate nanoplatelets have been alternatively combined with a cationic polyelectrolyte (polydiallyldimethylammonium chloride), a polyhedral oligomeric silsesquioxane or with alumina-coated silica nanoparticles, exploiting the layer-by-layer deposition. The obtained nanostructured assemblies have been app…
Photo-responsive biocompatible micelles were constructed from amphiphilic hyperbranched polyphosphate based polymer (denoted as HPHEEP-DNQ) and applied in the controlled release of coumarin 102. HPHEEP-DNQ was designed and synthesized by modification of hydrophilic hyperbranched polyphosphate (HPHEEP) with hydrophobic…
