To handle serious underwater oil spills, we have designed a functionally integrated device which can continuously clean up spilled oil underwater or on the water's surface in a directional manner, guided by a magnetic field, collecting the oil into the interior of the device and recycling it. The collecting efficiency…
Research interest in dynamic assemblies of coordination polymers (CPs) has been rising in recent years for the similarity with life systems in their self-adaptable morphologies and properties. However, monitoring of the assembly process and elucidating the nature for the morphological transformation are very challengi…
Effects of intermetallic phases on the creep behavior of AZ91 magnesium alloy have been studied. Thermally stable intermetallic phases such as Mg2Si and Mg3Sb2 are introduced deliberately in AZ91 alloy by the adding Si and Sb (0.5% Si, 0.5% Sb and 0.5% Si+0.2% Sb, all are in wt %). Creep tests were carried out at 150…
A simple and scalable method was proposed to fabricate graphene papers, and the graphene sheets were prepared using conventional chemical vapor deposition (CVD) method. The CVD graphene papers possess much higher electrical conductivity of 1097 S cm−1, compared with other reported carbon-related papers (graphene, carb…
Metal borohydrides offer high theoretical storage capacity for solid state hydrogen storage. This work is aimed at the mechanochemical synthesis of Yb(BH4)3 from LiBH4 and YbCl3. Different synthesis routes resulted in three new compounds, LiYb(BH4)4−xClx, α-Yb(BH4)3 and β-Yb(BH4)3. Their crystal structures have been d…
Ultrathin BN nanosheets (BNNSs) were prepared at 300 °C by a new variable-pressure one-step chemical synthesis route. It was found that the thickness of BNNSs decreased from 8 nm to 3 nm with the pressure increasing from 10 MPa to 90 MPa, and all the BNNSs are triangular in shape with a zigzag edge. These BNNSs have h…
A photo/redoxactive hexa-peri-hexabenzocoronene-porphyrin conjugate with a direct connection between the two chromophores was synthesised using a formylated hexaphenylbenzene precursor.
Tilapia fish scale, which facilitates both surface adsorption by hydroxyapatite and electrostatic interaction by collagen after boiling in alkaline environment, was used to prepare an adsorbent for the removal of the hazardous azo dye, Ponceau 4R. The prepared adsorbent was characterized by SEM, FT-IR and physical ads…
In this work, a simple and rapid method to selectively sort semiconducting-SWCNTs (sc-SWCNTs) with large diameters using regioregular poly(3-dodecylthiophene) (rr-P3DDT) is presented. The absorption spectra and Raman spectra demonstrated that metallic species of arc discharge SWCNTs were effectively removed after inte…
A highly fluorescent fluorinated semiconducting polymer dot (Pdot) with a quantum yield of up to 49% was developed. The fluorinated Pdot was eight times brighter in cell-labeling applications than its non-fluorinated counterpart, and was rod shaped rather than spherical.
Functional nanocomposites comprising of biomaterials and non-biomaterials are one of the main subjects of recent research due to their wide range of potential applications. Here, we demonstrate that the porous DNA hydrogel (Dgel) can be an excellent template for combining carbon nanotubes (CNTs) and polyaniline (PANI)…
The investigation of sub-nanosecond exciton dynamics in HgTe colloidal quantum dots using ultrafast transient absorption spectroscopy is reported. The transmittance change spectrum acquired immediately after pumping is dominated by a bleach blue-shifted by ~200-300 nm from the photoluminescent emission band. Compariso…
A number of passive film growth models have been advanced in the past, each founded on different assumptions and providing different rate laws. A new, generalized growth model has been developed and the numerical simulation of the transient behavior of oxide film growth on metals and alloys is reported here. This mode…
We developed different-shaped drug nanocrystals with similar hydrodynamic sizes and surface charges, and found that nanorods exhibited much higher in vitro and in vivo anticancer efficacy than that of nanospheres.
The increasing demand for graphene's industrial application requires a new route for its mass production with high quality. Here, we report a facile, green, highly efficient and cost effective method for preparing a large amount of high quality graphene flakes, which is by the repeated microwave assisted exfoliation o…
This paper describes a generalizable approach to the synthesis of monolithic multiscale micro/meso/macro-porous polymers with potential use in catalysis, gas separations and gas storage. The model system is based on hyperbranched polyimides synthesized via an unconventional route from dianhydrides and triisocyanates.…
Ultraviolet and vacuum ultraviolet spectra are reported for Ce3+ and Eu2+ singly doped into the Sr5(PO4)3Cl lattice, synthesized by a solid-state process. The maxima of the emission intensities are at 346 nm (Ce3+) and 442 nm (Eu2+), with lifetimes of 25 ns and 494 ns, respectively. The Ce3+ excitation spectra exhibit…
A large number of gold nanoparticles (ca. 3.8 nm in diameter) were homogeneously and effectively incorporated into thiol-functionalized poly(N-isopropylacrylamide) (PNIPAM) microgels through the well-known Au–thiol chemistry. Here, the thiol-functionalized PNIPAM microgels were obtained by carbodiimide-mediated amide…
This paper describes the biological consequences of presenting electrospun fibrinogen (FBG) to endothelial cells as a spatially organized nanofibrous matrix. Aligned and randomly oriented FBG nanofibers with an average diameter of less than 200 nm were obtained by electrospinning of native FBG solution. Electrophoreti…
Bacterial microcompartments are large proteinaceous structures that act as metabolic organelles in many bacterial cells. A shell or capsid, which is composed of a few thousand protein subunits, surrounds a series of sequentially acting enzymes and controls the diffusion of substrates and products into and out of the l…
