Constraints on the Emission and Viewing Geometry of the Transient Anomalous X-ray Pulsar XTE J1810-197

open access: yes, 2008
The temporal decay of the flux components of Transient Anomalous X-ray Pulsar XTE J1810-197 following its 2002 outburst presents a unique opportunity to probe the emission geometry of a magnetar.

Beyond Water: Deep Eutectic Solvents Enable Dye‐Sensitised Photocatalytic Hydrogen Production

open access: yesChemSusChem, Volume 19, Issue 9, 14 May 2026.
Dye‐sensitised photocatalytic H2 evolution is demonstrated for the first time in deep eutectic solvents (DESs). Carbazole‐based dyes with different hydrophobicity sensitise Pt@TiO2, revealing that heterogeneous dye–DES combinations maximise activity. Interfacial solvation and charge transfer govern enhanced hydrogen production under visible light. This

Magnetic Scaling Laws for the Atmospheres of Hot Giant Exoplanets

open access: yes, 2011
We present scaling laws for advection, radiation, magnetic drag and ohmic dissipation in the atmospheres of hot giant exoplanets. In the limit of weak thermal ionization, ohmic dissipation increases with the planetary equilibrium temperature (T_eq ...

Using Lignin and Spent Coffee Grounds as Bio‐Additives in 3D‐Printable Poly Lactic Acid/Multi‐Walled Carbon Nanotube Composites for Advanced Electronic Applications

open access: yesPolymer Composites, Volume 47, Issue 9, Page 8261-8272, 10 May 2026.
Bio‐based additives derived from lignin and spent coffee grounds (SCG) are used to enhance MWCNT dispersion in PLA composites, enabling improved electrical conductivity and reliable in material extruded strain‐gauge sensors. ABSTRACT In this work, three bio‐based additives, lignin, spent coffee grounds (SCG), and oil extracted from SCG (Ox‐SCG) were ...

Influence of salinity on the physiological conditions in mussels, Perna perna and Perna viridis (Bivalvia: Mytilidae).

open access: yesRevista de biologia tropical, 2003
El género Perna es exótico en Venezuela. En la actualidad Perna perna y Perna viridis coexisten y son explotados comercialmente de sus bancos naturales. El objetivo de este trabajo es determinar el efecto de la salinidad sobre la condición fisiológica de P. perna y P. viridis, mediante la relación ARN/ADN y Proteínas/ ADN.

Salinity and temperature tolerances of the green and brown mussels, Perna viridis and Perna perna (Bivalvia: Mytilidae)

open access: yes, 2017
Estudios recientes han infonnado de alteraciones del hábitat del mejillón marrón, P. pema. por el mejillón verde, P. viridis, desde su aparición en las costas del Golfo de Paria en 1993. En la actualidad P. viridis está desplazando al mejillón P. perna de sus bancos naturales en La Esmeral­da, Guatapanare y El Morro de Chacopata, Estado Sucre, y a ...
