Are the three hydroxyphenyl radical isomers created equal? – The role of the phenoxy radical –
We have investigated the thermal decomposition of the three hydroxyphenyl radicals (˙C6H4OH) in a heated microtubular reactor. Intermediates and products were identified isomer-selectively applying photoion mass-selected threshold photoelectron spectroscopy with vacuum ultraviolet synchrotron radiation. Similarly to t…
Liquid–solid spinodal decomposition mediated synthesis of Sb 2 Se 3 nanowires and their photoelectric behavior
The convenient synthesis of one-dimensional nanostructures of chalcogenide compounds with a visible band-gap is an essential research topic in developing next-generation photoelectronic devices. In particular, the design of a theoretically predictable synthesis process provides great flexibility and has a considerable…

Ni–Fe layered double hydroxide (LDH) nanosheets and hierarchical Ni–Fe LDH@MnO 2 spheres are synthesized by a facile and cost-effective approach for highly efficient ethanol electro-oxidation.
Ferro- and piezo-electric properties of a poly(vinyl fluoride) film with high ferro- to para-electric phase transition temperature
Excellent ferro- and piezo-electricity is observed for the first time in poly(vinyl fluoride) with a ferro- to para-electric transition at 168 °C, a coercive electric field of 120 MV m −1 and a relatively large piezoelectric coefficient of −11 pC N −1 .
Preparation of anti-fouling silicone elastomers by covalent immobilization of carboxybetaine
The surface-grafted carboxybetaine (CB) layer could enhance the biocompatibility of polydimethylsiloxane (PDMS) and reduce the adsorption of protein and adhesion of bacteria efficiently.

Composite of ultrathin SnS 2 and SnO 2 nanoflakes with conducting multiwalled carbon nanotube matrix as superior anode materials for lithium-ion batteries.
Thermoelectricity at the molecular scale: a large Seebeck effect in endohedral metallofullerenes
Single molecule devices provide a unique system to study the thermoelectric energy conversion at an atomistic level and can provide valuable information for the design of organic thermoelectric materials. Here we present a comprehensive study of the thermoelectric transport properties of molecular junctions based on C…
Supramolecular bimetallic assemblies for photocatalytic hydrogen generation from water
A series of supramolecular assemblies of the type [Ru(L-L)2(L'-L)MX2)](n+) are reported where L-L is 2,2'-bipyridine (bipy), 4,4'-di-tetra-butyl-bipyridine (tbbipy) or 4,4'-diethoxycarbonyl-2,2'-bipyridine (dceb), L-L' is tetrapyrido[3,2-a:2',3'-c:3'',2''-h:2''',3'''-j]phenazine (tpphz), 2,2':5',2''-terpyridine (2,5-b…
Axis-dependent magnetic behavior of C 60 and C 60 10+ . consequences of spherical aromatic character
The magnetic response of C60 has been studied and compared to its spherical aromatic counterpart C60(10+), focusing on the overall and local shielding tensors. A high axis dependence behavior at the outside region of the structure is characterized, unravelling a characteristic pattern of the local chemical shift aniso…
