Transport characteristics of organic solvents through carbon nanotube filled styrene butadiene rubber nanocomposites: the influence of rubber–filler interaction, the degree of reinforcement and morphology
The transport behaviour of some aromatic and aliphatic solvents through carbon nanotube filled styrene butadiene rubber composites has been investigated. The aim of the present work is to investigate the role of the sorption technique in analysing the compatibility and the reinforcing effect of MWCNTs as a filler in t…
Effect of steam on high temperature oxidation behaviour of alumina-forming alloys
Alternative light water reactor fuel cladding materials are being investigated to replace Zircaloy for enhanced accident tolerance, which involves oxidation resistance to steam environments at ≧1200°C for short times. As chromia-forming alloys and Ni-containing alloys are both undesirable for this application, the foc…
Three-dimensional Fe- and N-incorporated carbon structures as peroxidase mimics for fluorescence detection of hydrogen peroxide and glucose
could be detected with a linear range from 0.1 to 100 μM. Meanwhile, by integrating glucose oxidase on the Fe-Phen-CFs composite, sensitive detection of glucose is also achieved with a linear range from 0.5 to 200 μM and a limit of detection of 0.19 μM. Most importantly, such a novel TA/Fe-Phen-CFs system can be succe…
Under the lens: carbon nanotube and protein interaction at the nanoscale
The combination of the very different chemical natures of carbon nanotubes (CNTs) and proteins gives rise to systems with unprecedented performance, thanks to a rich pool of very diverse chemical, electronic, catalytic and biological properties. Here we review recent advances in the field, including innovative and ima…
A new and efficient red phosphor for solid-state lighting: Cs 2 TiF 6 :Mn 4+
A new red phosphor Cs 2 TiF 6 :Mn 4+ has been prepared by a facile cation exchange route, which can absorb the broad blue band and emit intense red light efficiently, and can be a potential candidate for application in indoor lighting WLEDs.
Three tetracoordinate Co( ii ) complexes [Co(biq)X 2 ] (X = Cl, Br, I) with easy-plane magnetic anisotropy as field-induced single-molecule magnets
Three mononuclear complexes [Co(biq)X2] (biq = 2,2'-biquinoline; X = Cl, Br, I) were prepared by a solvothermal method and characterized by single-crystal X-ray diffraction. In all three complexes the Co(ii) atom is tetrahedrally coordinated by one biq ligand bonded in a chelate manner and two halogenido ligands. Hydr…
Raman studies of A 2 MWO 6 tungstate double perovskites
The Raman spectra of seven A(2)MWO(6) tungstate double perovskites are analysed. Ba(2)MgWO(6) is a cubic double perovskite with Fm3[combining macron]m symmetry and its Raman spectrum contain three modes that can be assigned in a straightforward manner. A fourth mode, the asymmetric stretch of the [WO(6)](6-) octahedro…
Microwave shielding properties of Co/Ni attached to single walled carbon nanotubes
Cobalt and nickel nanoparticles attached to single-walled carbon nanotubes were prepared by the dc-arc discharge technique and showed a microwave shielding effectiveness value of 24 dB for a 1.5 mm thick sample in the frequency range 12.4–18 GHz.
Single-ion magnet behaviour of heptacoordinated Fe( ii ) complexes: on the importance of supramolecular organization
Supramolecular organization of a metal complex may significantly contribute to the magnetization dynamics of mononuclear SMMs. This is illustrated for a heptacoordinated Fe(II) complex with rather moderate Ising-type anisotropy for which a slow magnetization relaxation with significant energy barrier was reached when…
A soft–hard template approach towards hollow mesoporous silica nanoparticles with rough surfaces for controlled drug delivery and protein adsorption
layers, and the removal of the inner carbon core and CTAB to produce HMSNs. The obtained HMSNs possess spherical morphology, a mesoporous shell, and crumpled surfaces. The controlled experiments prove that the addition of 3-ammonia propyl triethoxy silane (APTES) is very crucial for the formation of desired HMSNs. The…

The singlet excited state of BODIPY promoted aerobic cross-dehydrogenative-coupling reactions under visible light
In contrast to previous studies, we disclose for the first time that the singlet excited state ((1)PS*) of BODIPY rather than the triplet excited state ((3)PS*) can drive C-H bond activation to form C-C and C-P bonds smoothly, which offers new methods to promote organic transformation under visible light irradiation.
