Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Quantitative Insights into Atomic Scale Oil–Clay Adhesion Governing Shale Oil Retention and Mobility

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Atomic force microscopy reveals a clear adhesion hierarchy between shale oil and clay minerals, governed by nanoscale surface chemistry. Strong interactions on chlorite and illite arise from abundant polar sites and cation bridging, whereas weaker coupling on montmorillonite limits interfacial binding.

Depositional Ice Nucleation on NX illite and Mixtures of NX illite with Organic Acids [PDF]

open access: yes, 2014
Mineral dust particles are efficient ice nuclei (IN). NX illite, a new atmospheric dust surrogate, has been suggested to better represent atmospheric dust.

Infrared Spectroscopic Predictions of Soil Properties for Agricultural Monitoring: Statistical and Soil Spectroscopic Considerations

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Pseudo‐independent validation (PIV) using regional datasets is common in visible‐to‐near‐infrared (vis–NIR) and mid‐infrared (MIR) spectroscopy studies and produces accurate predictions but is relevant only to regional‐scale monitoring of known sites.

DIFFERENTIATION AND BALANCE OF MINERALS DURING TRANSFORMATION OF THE OPEN SURFACE OF ARABLE SOILS UNDER THE IMPACT OF RAIN

open access: yesБюллетень Почвенного института им. В.В. Докучаева, 2019
During the model experiment the changes in the mineralogical composition of the open surface of arable soil (leached chernozem, gray forest soil, sod-podzolic soil) under the impact of raindrops under fallow conditions were studied.

Perspectives of High‐Resolution Mass Spectrometry in Soil Science

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Soil biogeochemical research requires specific, sensitive, and accurate methods to identify and quantify organic molecules in order to trace biochemical processes and assess element cycling in complex, heterogenous systems. High‐resolution mass spectrometry (HRMS) has evolved into a transformative tool for unraveling the complex chemical ...

Bio‐Derived Carbon Nanoparticles: A Green Amendment for Alleviating Heavy Metals in Soil–Plant Systems

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Heavy metal (HM) contamination of soil–plant systems poses persistent ecological and health risks, driving interest in nanoparticle‐based remediation. Although conventional chemically synthesized nanoparticles (CSNPs) are effective, their energy‐intensive production and residual toxicity limit sustainable deployment.
