Spatio‐Temporal Modeling of Land‐Use/Land‐Cover Change and Land Surface Temperature Using SVM and CA–Markov in Dilla Town, Ethiopia

open access: yesGlobal Challenges, Volume 10, Issue 4, April 2026.
Multi‐temporal Landsat imagery (2001, 2011, 2021) was used to map land use/land cover and retrieve land surface temperature, quantify change, and model future scenarios. Results indicate rapid expansion of built‐up land accompanied by declining mixed forest and cropland and increasing thermal hotspots.

Reconstruction of Core‐Surface Flows During the Last 3,300 Years

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Understanding the Earth's magnetic field evolution requires examining the fluid flow at the core‐mantle boundary that drives the changes over different timescales. The inversion process to derive core‐surface flow velocities from secular variation data encounters non‐uniqueness issues, necessitating a priori assumptions that yield different ...

Influence of annealing on the hydrogen bonding and the microstructure of diamondlike and polymerlike hydrogenated amorphous carbon films [PDF]

open access: yes, 1995
The influence of hydrogen incorporation on the microstructure of hydrogenated amorphous carbon (a-C:H) films has been studied in detail by applying several complementary methods, i.e., elastic recoil detection analysis (ERDA), hydrogen evolution, and ...

Evidence for Missing Geomagnetic Reversals From Geomagnetic Reversal Frequency Model Using Adaptive Kernel Density Estimation

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The existence of missing geomagnetic reversals has been proposed, with potential for new magnetostratigraphic age controls. We estimate geomagnetic reversal frequency from 0 to 155 Ma using adaptive‐bandwidth kernel density estimation (AKDE) to evaluate data sparseness and to assess how reversal frequency changes when recently identified ...

Tailored Nickel Oxide Interfacial Layers Unlock Enhanced Charge Dynamics in LaTiOxNy Thin Film Photoanodes

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 4, 17 February 2026.
This study highlights the importance of designing photoanode architectures for solar water splitting that align intrinsic material properties with functional interfaces to optimize the extraction of photogenerated charges. The incorporation of NiOx surface layers in LaTiO2.5N0.5 (LTON) thin film photoanodes exemplifies this approach by leveraging band ...

Thickness‐Driven Modulation of Electronic Transport in SnSe2‐grown Films by Low‐Temperature Atomic Layer Deposition

open access: yesAdvanced Electronic Materials, Volume 12, Issue 2, 21 January 2026.
Low‐temperature ALD enables scalable growth of SnSe2 films with precise thickness and crystallinity control, essential for nanoelectronics. Using a reactive Se precursor, films transition from nearly defect‐free single crystals (∼20 nm) to polycrystalline (∼100 nm) with thickness, directly impacting transport properties.

Modelling the Effects of Urban Growth on Land Surface Temperature and Carbon Emissions Through Geospatial and Machine Learning Techniques in Gazipur, Bangladesh

open access: yesGeo: Geography and Environment, Volume 13, Issue 1, January‐June 2026.
Short Abstract This study analyses the impact of rapid urban expansion on seasonal land surface temperature (LST) and carbon emissions in Gazipur, Bangladesh, from 2003 to 2023, with projections to 2043 using geospatial and machine learning models. Results indicate a significant increase in built‐up area and LST, as well as strong correlations between ...
