Fossilised geothermal surface features of the Whitianga Volcanic Centre (Miocene), Coromandel Volcanic Zone, New Zealand: Controls and characteristics
(Elsevier Science, 2019-09)
The Late Miocene Whitianga Volcanic Centre of the Coromandel Volcanic Zone, North Island, New Zealand, is host to 18 known, siliceous and intensely silicified deposits including: silicified volcanics; sediments of inferred ...
Superficies fotográficas: el resto, el trazo y las imágenes en crisisPhotographic surfaces: the rest, the trace and the images in crisis
(Universidad de Malaga. Facultad de Ciencias de la Comunicación, 2021-01)
Este artículo toma, por un lado, como punto de inflexión la crisis argentina de 2001 para enhebrar ciertas obras de la fotografía artística argentina que cruzan arte y política, evocando una de las experiencias de aquel ...
Superficial self-diffusion coefficient in Ih-ICE
(Masaryk University, 2020-07)
The evolution of the grain boundary groove in a bicrystalline ice sample was studied in this work. The groove is formed by the intersection of the grain boundary with the free surface. The bicrystalline ice sample had an ...
Density Functional Theory Study of the Adsorption of Au Atom on Cerium Oxide: Effect of Low-Coordinated Surface Sites
(American Chemical Society, 2009-03)
Periodic density functional calculations within the LDA+U and GGA+U formalisms have been carried for slabs representing the CeO2(111) surface and a stepped model surface. The surface active sites have been determined and ...
Intermolecular conical intersections in molecular aggregates
(Nature Publishing Group, 2021-01)
Conical intersections (CoIns) of multidimensional potential energy surfaces are ubiquitous in nature and control pathways and yields of many photo-initiated intramolecular processes. Such topologies can be potentially ...
Unified theory of adsorption, pore-filling and wetting
(American Physical Society, 2007-12)
Gases adsorb readily on surfaces and inside porous materials when there exists a sufficiently strong attraction provided by these materials. In the extreme opposite situation, little or no adsorption occurs when the ...
Effect of Temperature and Potassium Chloride Impurity on the Relative ⟨101̅0⟩ Tilt Grain Boundary and Surface Free Energies in Ice
(American Chemical Society, 2014-09)
The ratio of the grain boundary free energies relative to the surface free energies γgb/γs can be determined by measuring the root angles of the grooves formed at the intersection of the grain boundary with the free surface. ...
Classification of dispersion equations for homogeneous, dielectric-magnetic, uniaxial materials
(Optical Society of America, 2006-12)
The geometric representation at a fixed frequency of the wave vector (or dispersion) surface ω(k) for lossless, homogeneous, dielectric-magnetic uniaxial materials is explored for the case when the elements of the relative ...
Polar caps during geomagnetic polarity reversals
(Wiley Blackwell Publishing, Inc, 2019-02)
Changes in the Earth’s magnetic field can deeply modify the polar caps and auroral zones, which are the regions of most frequent precipitation of energetic particles. The present field is characterized by a dominant dipole ...
Improved Sea Surface Height from Satellite Altimetry in Coastal Zones: A Case Study in Southern Patagonia
(Institute of Electrical and Electronics Engineers, 2017-08)
High-resolution 20-Hz Jason-2 satellite altimetry data obtained from crossing tracks numbered 52 and 189 in San Matias Gulf, Argentina, are compared with a 22-month-long time series of sea level measured by a bottom pressure ...
