Electronics 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
New 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 ...

New 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 ...

Small, 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.

Rapidity equilibration in d + Au and Au + Au systems [PDF]
The European Physical Journal A, 2006 In a Relativistic Diffusion Model (RDM), the evolution of net-proton rapidity spectra with sqrt(s_NN) in heavy systems is proposed as an indicator for local equilibration and longitudinal expansion. The broad midrapidity valley recently discovered at RHIC in central Au + Au collisions at sqrt(s_NN)= 200 GeV suggests rapid local equilibration which is ...

Menstrual experience of adolescents in the USA: protocol for a scoping review
BMJ Open, 2021 Introduction In recent years, there has been a growing desire to address issues related to menstruation, particularly for adolescent girls. In low-income and middle-income countries, prior literature review of the adolescent menstrual experience suggests

Small Science, Volume 4, Issue 2, February 2024.This article reports a porous Fe3O4 core–Au satellite nanocomposite prepared using a selective etching strategy for realizing advanced oxidation processes under visible light. The porous structure of the synthesized nanomaterial considerably enhances its photocatalytic activity, surface area, and light absorption.

Revista Facultad de Ingeniería Universidad de Antioquia, 2017 Los fotocatalizadores Pt-TiO2 y Au-TiO2 se prepararon por fotodeposición del metal noble sobre el TiO2 sulfatado. Se encontró que las propiedades ópticas, el estado de oxidación y el tamaño de partícula de las especies metálicas (Pt o Au) juegan un papel
