Experimental verification of the dominant influence of extended carbon networks on the structural, electrical and magnetic properties of a common soot
Autor: T Jones, P F Nolan, L J Dunne, A D Hudson, J Munn, P Kathirgamanathan, Mauricio Terrones, J Fernandez
Publikováno v: Journal of Physics: Condensed Matter. 9:10661-10673
Common soots are disordered carbonaceous materials containing several per cent of heteroatoms. A question of some importance is to what extent pure carbon networks dominate the properties of common soots. Here, we report the results of a comparative

Electrical, magnetic and structural characterization of fullerene soots
Autor: P Kathirgamanathan, J Munn, Harold W. Kroto, U. Heinen, L J Dunne, A. D. Clark, D. G. Reid, A. K. Sarkar, J. P. Hare, J Fernandez
Publikováno v: Journal of Physics: Condensed Matter. 8:2127-2141
Although it is some five years since fullerenes were extracted in macroscopic quantities from the black, superficially amorphous sooty deposits produced by a carbon arc under helium, little is known in detail about the structure of the deposit or its

Continuous Phase Transitions and Orientational Ordering in Monolayers of Zwitterionic Amphiphilic Molecules at Fluid Interfaces
Autor: P. Katbamna, W. Ford, D. A. Lavis, B. W. Southern, L. J. Dunne
Publikováno v: physica status solidi (b). 178:335-342
Experimental and theoretical evidence is presented which shows that orientational ordering of highly polar head groups in monolayers of amphiphilic molecules (zwitterionic 2 amino-tetradecanoic acid) at fluid interfaces produces a smooth continuous p

The condensate fraction in high-Tccuprate superconductors
Autor: T P Spiller, L J Dunne
Publikováno v: Journal of Physics: Condensed Matter. 4:L563-L566
Although it is some years since the discovery of high-Tc cuprate superconductors, the nature and doping dependence of the condensate in such materials is still uncertain. There is no consensus as to whether the supercurrent is carried by a macroscopi

The Relative Energies of Ionic Structures for the High-Tc Superconductor YBa2Cu3O7 and Implications for the Superconducting Mechanism
Autor: L. J. Dunne, J. N. Murrell, N. Floros
Publikováno v: physica status solidi (b). 159:781-786
Madelung potentials are calculated for several choices of formal oxidation states of the ions in the high temperature superconductor YBa2Cu3O7. For p-type CuO2 planes a slightly lower energy is found for a lattice with holes localised on copper (Cu3+

Excited-State Molecular Superconductivity
Autor: L. J. Dunne, A. Tang Kai
Publikováno v: physica status solidi (b). 157:657-666
The possibility of non-equilibrium excited state molecular superconductivity is discussed and applied to the problem of photosynthetic electron transfer. Die Moglichkeit von angeregter Nichtgleichgewichts-Molekularsupraleitung wird diskutiert und auf

Molecular graphics and the classical adiabatic and nonadiabatic dynamics of small polyatomic reactions
Autor: N. L. Bourner, L. J. Dunne
Publikováno v: Journal of Molecular Graphics. 5:129-132
A molecular graphics system for displaying the classical trajectories of small polyatomic molecule dynamics has been developed. The system can be used in adiabatic and nonadiabatic dynamic studies. Applications to the photodissociation of water at 10

Statistical mechanics of anomalous thermal effects in monolayers
Autor: L J Dunne, G M Bell
Publikováno v: Journal of Physics C: Solid State Physics. 12:4137-4149
The monolayer is represented here by a two-dimensional lattice model in which a molecule in the singly bound state is a 'monomer' occupying one lattice site while a molecule in the doubly bound or 'extended' state is a 'dimer' occupying two neighbour

Electronic Degeneracies, Inelastic Processes, and Bohm-Aharonov Magnetoresistance Oscillations in Ordered Normal-Metal Rings
Autor: L. J. Dunne
Publikováno v: physica status solidi (b). 154:727-731
A model is presented for magnetic flux dependent inelastic scattering processes in cyclic systems. This goes beyond previous work which assumes flux independent scattering processes. It is suggested that the model is of relevance to the interpretatio
