Knowledge-based systems and geological survey [PDF]

open access: yes, 2005
This personal and pragmatic review of the philosophy underpinning methods of geological surveying suggests that important influences of information technology have yet to make their impact.

Volcano‐Inspired Dual‐Carbon Network Aerogel for High‐Performance Solar Evaporation With Edge‐Directed Salt Crystallization and Recovery

open access: yesAdvanced Science, EarlyView.
A volcano‐inspired dual‐carbon aerogel featuring hierarchical conduits and an outer carbon‐fiber shell directs rapid water transport, confines heat, and enables directional salt migration. Radial temperature gradients in the conical structure trigger Marangoni‐driven edge‐localized salt crystallization while maintaining an unobstructed photothermal ...

Assessing Photovoltaic Recycling Capacities and Policy Gaps in the European Union

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study maps photovoltaic recycling capacity in the EU and key global regions, highlighting gaps between growing waste volumes and available infrastructure. It combines survey insights and policy analysis to identify recycling bottlenecks and offers recommendations to boost circularity in the solar sector.

Sea-floor tectonics and submarine hydrothermal systems [PDF]

open access: yes, 2005
The discovery of metal-depositing hot springs on the sea floor, and especially their link to chemosynthetic life, was among the most compelling and significant scientific advances of the twentieth century. More than 300 sites of hydrothermal activity and

The Geography of Success: A Spatial Analysis of Export Intensity in the Italian Wine Industry

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper investigates the paradox of how Italy's fragmented, SME‐dominated wine industry achieves global export success. Moving beyond purely firm‐centric explanations, we test whether export intensity is spatially dependent, clustering geographically in regional ecosystems.

Geology of Rookery Creek zinc-lead showings, Cornwallis Island, Nunavut

open access: yes, 2002
Four zinc-lead showings are known from the Middle Ordovician Bay Fiord and Thumb Mountain formations at Rookery Creek on western Cornwallis Island. Mapping of the Rookery Creek area was updated at 1:50 000 scale. The geology is complex, with four fault sets superimposed on a broad anticlinorium.

Implications of convection in the Moon and the terrestrial planets [PDF]

open access: yes
The early thermal and chemical evolution of the Moon is discussed. The rubidium-strontium, neodymium-samarium, and uranium-thorium-lead systems were studied.

Evidence from Rb–Sr mineral ages for multiple orogenic events in the Caledonides of Shetland, Scotland [PDF]

open access: yes, 2015
Shetland occupies a unique central location within the North Atlantic Caledonides. Thirty-three new high-precision Rb–Sr mineral ages indicate a polyorogenic history.

3D investigation and modeling of the geometric effects on porosity in packed beds

open access: yesAIChE Journal, EarlyView.
Abstract In porous beds, physical boundaries restrict particle arrangement, leading to inhomogeneous porosity. This paper reports on the porosity profiles that are the result of geometric effects on monodisperse packed beds in cylindrical and cubic arrangements. Special focus is given to the influence of edges and corners in cubic geometries.
