Atomic Layer Etching of Titanium Nitride With O3 and NbCl5

ChemNanoMat, Volume 12, Issue 5, May 2026.
TiN is etched with ALE using O3 and NbCl5 at 200–350 °C. Surface roughening is minimal and even smoothing is observed at 200 °C. Four‐point probe measurements show little effect on the resistivity even at low thicknesses. XPS shows that very small amount of residue is left from the etchant.

Progress Toward Efficient Wide‐Gap Cu(In,Ga)(S,Se)2 Thin‐Film Solar Cells

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 5, Page 567-588, May 2026.
Wide‐gap Cu (In,Ga)(S,Se)2 thin‐film solar cells are studied in view of their performance, limitations, and opportunities for further optimization. Different sources of open circuit voltage limitations were discussed and weighted. Interface recombination appears the main recombination channel, which however can be influenced heavy alkali treatment ...

Application of CFD to sonic boom near and mid flow-field prediction [PDF]

A 3-D parabolized Navier-Stokes (PNS) code was used to calculate the supersonic overpressures from three different geometries at near- and mid-flow fields. Wind tunnel data is used for code validation.

Modeling of water infiltration in hydrophobic‐over‐wettable two‐layer columns

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract This paper presents a new piecewise model for simulating one‐dimensional infiltration curves in two‐layer finite columns consisting of a hydrophobic layer overlaying wettable soil. The model combines a physics‐based equation for infiltration in water‐repellent substrates with an analytical framework for ponded conditions.

Anisotropic Permeability Pathways Controlled by Intraslab Stress Heterogeneity in the Philippine Sea Slab Beneath the Ryukyu Arc

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Intermediate‐depth intraslab earthquakes in the Philippine Sea Plate occur at depths of 100–200 km beneath the Ryukyu Arc and are widely interpreted as manifestations of slab dehydration; however, the spatial variability in continuity of the volcanic front and the asymmetric distribution of volcanic activity are poorly explained by existing ...

Block‐in‐Matrix Deformation and Veining in Alpine Subducted Oceanic Metasediments at Blueschist Facies Conditions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract In subduction zones, the locked seismogenic zone is bordered by an upper and a lower transition zone. In these transition zones, deformation is primarily accommodated by an interplay of diffuse viscous deformation within a weak matrix and brittle deformation in stiffer bands and blocks.

Unraveling the Mystery of Melt Migration in Migmatites: From Channeling Instability to Pattern Formation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Melt migration in partially molten rocks is commonly described by porous flow models controlled by the hydro‐mechanical compaction length, which effectively explains melt extraction at mid‐ocean ridges. However, this framework cannot account for the paradoxical accumulation of small melt fractions into rhythmic leucosome–melanosome bands in ...

Enhancing 2D Hydrodynamic‐Based Flash Flood Simulations in Mountain Catchments: Analytical Insights From a Novel Steep‐Slope Shallow Water Framework

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Flash floods frequently occur in steep mountainous catchments, where topographic gradients play a crucial role in concentrating and accelerating runoff processes. Two‐dimensional (2D) shallow water equations (SWE) are widely used to simulate such events; however, these equations are classically derived assuming small bottom slopes, typically ...
