Ultrafast Synthesis of a Non‐Noble FeCoNiCrZn Multi‐Element Alloy Electrocatalyst for Alkaline Oxygen Evolution Reaction

open access: yesCarbon Energy, EarlyView.
A nanoporous carbon‐coated FeCoNiCrZn multi‐element alloy on carbon cloth (FeCoNiCrZn‐C@CC) is fabricated by ultrafast pulsed laser irradiation. It has excellent OER performance, achieving an overpotential of only 233 mV at 10 mA cm−2 and remarkable stability for 94 h at 250 mA cm−2, which is due to multiple factors.

Geochemistry and 40Ar/39Ar age of Early Carboniferous dolerite sills in the southern Baltic Sea [PDF]

open access: yesEstonian Journal of Earth Sciences, 2015
The Early Carboniferous magmatic event in the southern Baltic Sea is manifested by dolerite intrusions. The presumable area in which the dolerite intrusions occur ranges from 30 to 60 km in east–west direction, and is about 100 km in north–south ...

Thermal history of the Labrador rifted margin: Insights from apatite and zircon (U-Th)/He and apatite fission track thermochronology

open access: yes, 2021
A study of the thermal history of Mesozoic rifting in the Labrador Sea, providing low-temperature thermochronology data including apatite and zircon (U-Th)/He and apatite fission track data from the Labrador margin of the rift.The Labrador margin ...

Analogue and numerical modelling of continental rifting: New insights from quantitative deformation analyses [PDF]

open access: yes, 2022
Extension of the continental lithosphere leads to the formation of rift basins. If extension succeeds to the point of lithospheric rupture eventually, new oceanic basins form with the continental remnants as conjugate passive margins on either side.

Membrane‐Permeable Nucleoside T‐1106 Diphosphate and Triphosphate Analogues as Antiviral Pronucleotides

open access: yesChemistry – A European Journal, EarlyView.
Favipiravir (T‐705) and the non‐fluorinated counterpart (T‐1106) are antiviral agents that inhibit the RNA‐dependent RNA polymerase (RdRp) of various RNA viruses. The antiviral efficacy of nucleoside analogues is strongly dependent on their intracellular activation by cellular kinases to produce their corresponding triphosphate metabolites (T‐705‐RTP ...

Tectono-Thermal Evolution of the Red Sea Rift

open access: yesFrontiers in Earth Science, 2021
The Oligocene-Recent Red Sea rift is one of the preeminent examples of lithospheric rupture in the recent geological past, forming the basis for many models of how continental breakup occurs and progresses to the formation of new oceanic crust ...

Seismic structure of the continental margin of French Guiana: implications for the rifting and early spreading of the equatorial Atlantic [PDF]

open access: yes, 2007
Recent studies of passive continental margins suggest that the rifting process produces a variety of structural styles. The along-strike continuity of these rifted margins is punctuated by significant lateral offsets, known as transform margins.

Permeability of granite from a shallow buried mountain pipe gallery tunnel under unloading confining pressure

open access: yesDeep Underground Science and Engineering, EarlyView.
Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

open access: yesGeological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Analogue Modelling of Inverted Oblique Rift Systems [PDF]

open access: yes, 2005
The geometric evolution of brittle fault systems in inverted oblique and offset rift systems has been simulated using scaled sandbox analogue models. Dry fine-grained quartz sand was used to represent the brittle upper crust.
