Fatty Acids Analysis of Four Pistacia Species by Gas Chromatography Coupled With Mass Spectrometry via Multivariate Chemometrics

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Pistacia species are widely used in traditional medicine, particularly for wound healing. This study investigated the fatty acid composition of fruits from four Pistacia species collected from various regions of Algeria. Dried fruits of Pistacia lentiscus L. were extracted using hexane in a Soxhlet apparatus.

3D structural model of the Polish Basin

open access: yesTectonophysics, 2005
Abstract A 3D structural modelling of the Permian–Mesozoic Polish Basin was performed in order to understand its structural and sedimentary evolution, which led to basin maturation (Permian–Cretaceous) and its tectonic inversion (Late Cretaceous–Paleogene).

Thermodynamic and structural aspects of the potential energy surface of simulated water

open access: yes, 2000
Relations between the thermodynamics and dynamics of supercooled liquids approaching a glass transition have been proposed over many years. The potential energy surface of model liquids has been increasingly studied since it provides a connection between

Cracking the Code of RuO2 Corrosion: A Theoretical Exploration of Potential‐Driven Switches Between Oxidative and Reductive Pathways

open access: yesChemElectroChem, EarlyView.
Applied potential dictates RuO2 corrosion pathways—favoring either full oxidation or hydroxylated species. Dopants reshape stability windows, guiding selective dissolution and enhancing durability. Ruthenium dioxide (RuO2) is a benchmark catalyst for the oxygen evolution reaction (OER) in acidic media but suffers from slow dissolution under operating ...

Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor

open access: yesCytoskeleton, EarlyView.
ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

Paleogeographic and structural evolution of northwestern Africa and its Atlantic margins since the early Mesozoic

open access: yes, 2017
The geological evolution of northwestern Africa and its continental margins is investigated in the light of nine Meso-Cenozoic paleogeological maps, which integrate original minimal extent of sedimentary deposits beyond their present-day erosional limits.

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

open access: yesThe Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.
