The oxidation of adsorbed CO is a key reaction in electrocatalysis. It has been studied extensively on both extended model surfaces and on nanoparticles; however, correlation between the two is far from simple. Molecular insight into the reaction is often provided using in situ IR spectroscopy; however, practical challenges mean in situ studies on nanoparticles have yet to provide the same leve...

An operationally simple, user and eco-friendly synthetic protocol for the synthesis of [Rh(acac)(CO)(NHC)] complexes is described. Insights into mechanism are provided using operando spectroscopy. The spectroscopic fingerprints these correlated to NHCs reported electron-donating descriptor values, highlighting a new strategy evaluate carbenes’ electronic properties. assessment in catalytic appl...

Magnetic circular dichroism ~MCD! has been measured for ferromagnetic CoS2 in the S 2p , Co 2p and 3p core absorption regions. MCD in the S 2p region is discussed in terms of the exchange splitting of the unoccupied band. The Co 2p MCD has revealed that the orbital angular momentum of the Co 3d state remains finite in spite of its low-spin configuration. This situation is confirmed by a simple ...

Self-assembly between simple unsymmetrical ligands, such as 1-(3-pyridyl)-2-(4-pyridyl)ethene (L(1)) and 1-methyl-1'-(3-pyridyl)-2-(4-pyrimidyl)ethene (L(2)), and Co(NCS)(2) affords the unprecedented two-dimensional grid coordination polymers [Co(L(1))(2)(NCS)(2)](infinity) (1) and [Co(L(2))(2)(NCS)(2)](infinity) (2), respectively, with novel topological features which cannot be achieved using ...

In this paper we present a framework in which issues such as mobility and security in the presence of firewalls can be studied. The framework is based on a simple language where mobility is expressed as atomic actions and the behaviour of a firewall is described as logical formulae. We also separate the role of co-ordinators from normal user processes. Co-ordinators can reconfigure firewalls ba...

The main purpose of the paper is to study hyperkähler structures from the viewpoint of symplectic geometry. We introduce a notion of hypersymplectic structures which encompasses that of hyperkähler structures. Motivated by the work of Kronheimer on (co)adjoint orbits of semi-simple Lie algebras [10] [11], we define hyper-Lie Poisson structures associated with a compact semi-simple Lie algebra a...
