Quarkonium production from d + Au to Au + Au collisions

open access: yesThe European Physical Journal C, 2005
The PHENIX experiment measured J/ $\psi$ production in pp, d + Au and Au + Au reactions at $\sqrt{s_{NN}}$ = 200 GeV over a wide range of rapidity and transverse momentum ...

Flexible low‐cost cardiovascular risk marker biosensor for point‐of‐care applications

open access: yesElectronics Letters, Volume 51, Issue 22, Page 1746-1748, October 2015., 2015
The detection and quantification of protein on a laser written flexible substrate for point‐of‐care applications are described. A unique way of etching gold on polyethylene terephthalate (PET) substrate is demonstrated by reducing the damage that may be caused on PET sheets otherwise. On the basis of the quantity of the C‐reactive protein (CRP) present

Some Recent Results on Pair Correlation Functions and Susceptibilities in Exactly Solvable Models

open access: yes, 2006
Using detailed exact results on pair-correlation functions of Z-invariant Ising models, we can write and run algorithms of polynomial complexity to obtain wavevector-dependent susceptibilities for a variety of Ising systems.

Surface plasmon resonant splitting and merging due to infrared incidence through thermal imaging lens

open access: yesElectronics Letters, Volume 51, Issue 15, Page 1170-1172, July 2015., 2015
In previous work, the present authors discovered the resonant splitting phenomenon of a plasmonic perforated gold film (PGF), as the incident light comes in the polar angle. However, in reality, the light through the imaging lens could be incident on the PGF not only in the polar angle but also in the azimuth angle.

Fine and super‐fine gold in mine waste from a coastal placer in southern New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 68, Issue 2, Page 327-341, June 2025.
ABSTRACT Reprocessing of mine wastes is a growing procedure around the world, in order to extract more resources from already‐mined rocks. Mineralogical and geometallurgical investigations are useful for planned reprocessing, and in this study at Round Hill placer gold mine we characterise fine (<100 µm) and super‐fine (micron‐scale) particulate gold ...

Colloque « Au théâtre, au cinéma : au féminin » [PDF]

open access: yesLabyrinthe, 2000
Le Centre d’etudes feminines de l’Universite de Paris-VIII est le seul lieu institutionnel dote d’une equipe doctorale qui propose de reflechir aux problematiques de la difference sexuelle, et des differences en general. Les etudes feminines ont recemment organise, sous la direction de Mireille Calle-Gruber, un colloque sur les rapports du theâtre et ...

Redistribution of fine gold from hydrothermal sources to sedimentary sinks, Rakaia River, Canterbury, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 68, Issue 2, Page 282-303, June 2025.
ABSTRACT The Rakaia River in the South Island of New Zealand is a unique catchment in which to trace active detrital gold transport, deformation and concentration from near‐coeval orogenic sources. The catchment hosts widespread small late Cenozoic hydrothermal alteration zones, some of which are gold‐bearing, in actively rising and eroding mountain ...

Synergistic Metal‐Support Interactions in Au/GaN Catalysts for Photoelectrochemical Nitrate Reduction to Ammonia

open access: yesSmall, Volume 21, Issue 11, March 19, 2025.
A solar‐driven photoelectrochemical system is presented for sustainable NH3 production via NO3− reduction, addressing the energy demands of conventional processes. In this system, Au nanoclusters on GaN nanowires enable a tandem catalysis mechanism: NO₃⁻ reduces to NO2− on GaN, followed by NH3 synthesis on Au.
