Quantifying the Form‐Flow‐Saltation Dynamics of Aeolian Sand Ripples
Journal of Geophysical Research: Earth Surface, Volume 130, Issue 10, October 2025.Abstract Ripples are the most fundamental and ubiquitous aeolian bedforms formed on sandy surfaces, but their small size and fast response times make them inherently difficult to measure. However, these attributes also make ripples excellent flow indicators, and they have been used extensively in planetary locations for this purpose.

Sand Dune Dynamics Exploiting a Fully Automatic Method Using Satellite SAR Data
Remote Sensing, 2020 This work presents an automatic procedure to quantify dune dynamics on isolated barchan dunes exploiting Synthetic Aperture RADAR satellite data. We use C-band datasets, allowing the multi-temporal analysis of dune dynamics in two study areas, one ...

Bubble Printing of Anisotropic Clay Nanotubes
Advanced Optical Materials, Volume 13, Issue 25, September 3, 2025.Bubble printing patterns of lyotropic liquid crystal nanotubes form toroidal or linear patterns depending on laser movement and colloidal stability. Long nanotubes create radial filament bundles, while poor electrostatic repulsion hinders deposition.

ChemistrySelect, Volume 10, Issue 34, September 8, 2025.Investigation of flavonoid extract of Hyoscyamus albus L. Abstract The current study aimed to determine the phytochemical composition of the flavonoid‐rich extract of Hyoscyamus albus L. (FEHA), collected from the Khenchela region, and to investigate its multiple bioactivities. Phytochemical profiling was explored using LC‐MS and FTIR.

Pioneering Evidence of the Dynamics of Water Vapor and CO2 Fluxes in Sahara Desert Soils
Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 9, September 2025.Abstract Soil CO2 flux (Fc) is a major component of the global carbon balance. It is often overlooked in arid regions as low soil moisture restricts microbial and root respiration. Studies in the last decades challenge this paradigm, reporting an anomalous diurnal cycle of Fc in arid regions. This diurnal cycle is thought to be initiated by geochemical

Dynamic Evaluation of Barchans in Band-e-Rig Kashan in the Period 2013 to 2019 [PDF]
کاوشهای جغرافیایی مناطق بیابانی, 2022 IntroductionWind erosion and the formation of sand dunes are common phenomena in many arid regions around the world. More than 100 types of sand dunes have been classified by geomorphologists based on shape and size criteria (Lancaster, 1995). One of the

A model of Barchan dunes including lateral shear stress
, 2005 Barchan dunes are found where sand availability is low and wind direction quite constant. The two dimensional shear stress of the wind field and the sand movement by saltation and avalanches over a barchan dune are simulated.
