Atmospheric ice nuclei in the Eyjafjallajökull volcanic ash plume [PDF]

, 2011
Explosive volcanism affects weather and climate. Primary volcanic ash particles which act as ice nuclei (IN) can modify the phase and properties of cold tropospheric clouds.

Major engineering breakthrough of Well XA‐1, the deepest ten‐thousand‐meter well in a global sedimentary basin

Deep Underground Science and Engineering, EarlyView.
Well XA‐1, completed at a true vertical depth of 11 156 m in the Shawan Sag of the Junggar Basin, is the deepest predominantly near‐vertical well drilled in a sedimentary basin. The figure shows the basin's tectonic framework and well location (a), a structural cross‐section spanning the Shawan Sag and adjacent uplifts (b), and the stratigraphic column

Een archeologisch bureau-onderzoek en een karterend inventariserend veldonderzoek door middel van boringen voor Oude Hoevenseweg 3 te Tricht, gemeente Geldermalsen (Gld): ARC-Rapporten 2011-87

, 2011
De onderzoekslocatie ligt in het rivierengebied, op de Beddinggordel van Schaik die actief was van 4137 tot 2880 v. Chr. Hierdoor heeft de onderzoekslocatie een hoge trefkans op archeologische resten uit de periode vanaf de Bronstijd. Op de beddinggordel

Constructed Red Phosphorus/BiVO4 S‐Scheme Heterojunction for Efficient Photocatalytic Overall Water Splitting

EcoEnergy, EarlyView.
An S‐scheme red phosphorus/BiVO4 heterojunction is presented, where red phosphorus served as the water reduction site, and BiVO4 functioned as the water oxidation site. Because it has a built‐in electric field that helps charge transfer and separation, red phosphorus/BiVO4 works very well in the photocatalytic overall water splitting process.

Een verkennend inventariserend veldonderzoek door middel van boringen voor de verbreding van de N31 te Harlingen (F): ARC-Rapporten 2011-71

, 2011
Het onderzoeksgebied ligt in het noordelijke zeekleigebied, in het westen van Westergo. Binnen Westergo zijn vanaf het begin van het Holoceen kwelderwallen ontstaan die vooral in de periode IJzertijd – Romeinse Tijd intensief zijn bewoond. In het noorden

Decorating Carbon Nitride via the Integration of Phosphorylation with Carbon Self‐doping toward Enhanced Photocatalytic Hydrogen Evolution

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The electron transfer from the grafted ATMP to the adjacent heptazine ring can induce the proton transfer of the hydroxyls on ATMP to Pt co‐catalyst nanoparticles. This coupling of proton transfer and electron transport also promotes the separation and transport of charge carriers and therefore advances the performance of photocatalytic hydrogen ...

From Dome to Disease: The Respiratory Toxicity of Volcanic Cristobalite [PDF]

, 2012
Exposure to fine-grained volcanic ash can potentially cause acute and chronic respiratory disease. The toxicity of ash is likely to vary depending on the type and style of eruption; eruptions at dome-forming volcanoes, in particular, can produce ash ...

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Carbon emissions along divergent plate boundaries modulate icehouse-greenhouse climates

Communications Earth & Environment
The exchange of carbon between oceanic plates, the deep Earth, and the atmosphere plays a significant role in modulating global climate. Icehouse-greenhouse climate fluctuations have been attributed to changes in palaeogeography and solid Earth degassing,
