Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

Sedimentology, Volume 73, Issue 6, Page 2381-2416, October 2026.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...

Direct Steam Generation in Parabolic Trough Collectors

Energy Procedia, 2014
Existing commercial parabolic trough power plants use thermal oil as a heat transfer fluid, with working temperatures in the region of 400ºC. In order to achieve more efficient generating systems, a second generation of parabolic troughs that operate at temperatures higher than 400ºC is being developed.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Indoor thermal loss test on small-size solar receiver (UF-RT01) for process heat application

Solar Energy Advances, 2021
The parabolic trough collector is one of the most promising technologies for medium temperature application. The energy of solar radiation is directed by parabolic mirrors into cylindrical receivers and transmitted to a heat transfer fluid.

Thermal Behavior of Radiative Darcy–Forchheimer Nanofluid Flow With Heat Source/Sink Effects

Engineering Reports, Volume 8, Issue 9, September 2026.
Radiative Darcy–Forchheimer nanofluid flow in a porous medium is numerically analyzed with heat source/sink effects. Radiation enhances heat transfer and boundary layer thickness, while increasing Forchheimer resistance suppresses velocity, providing insights for optimizing thermal management in high‐temperature porous systems.
