Dimethyl‐, Diethyl‐, and Propylene Carbonates: An Emerging Class of Green Solvents for Organic Synthesis

The Chemical Record, EarlyView.
This review highlights recent advances in the use of organic carbonates, dimethyl carbonate (DMC), diethyl carbonate (DEC), and propylene carbonate (PC), as solvents in organic synthesis. Based on over seventy studies from the past 6 years, it shows their application in different organic reaction types, emphasizing their role in safer and more ...

Comparative analysis of saturated–unsaturated shear strength under undrained loading: Experimental validation and ANN prediction of clayey soils

AIP Advances
Geotechnical designs and analyses of earth structures and foundations exclusively involve the assessment and consideration of unsaturated soil shear strength. The laboratory testing equipment and methods for predicting the unsaturated soil shear strength

Tributyltin Protumorigenic Effects Targeting Prostate Cancer Cell Metabolism, Proliferation, Migration, and Invasion

Environmental Toxicology, EarlyView.
ABSTRACT Prostate cancer (PCa) is an endocrine‐related cancer highly dependent on androgenic signaling. Beyond hormone dependence, extrinsic factors play a significant role in the risk of developing PCa, which raises concern about the influence of environmental compounds such as endocrine‐disrupting chemicals (EDCs). Tributyltin (TBT) is an EDC used in

Experimental unsaturated soil mechanics

, 2002
In this general report, experimental systems and procedures of investigating the hydro-mechanical behaviour of unsaturated soils are presented. The water retention properties of unsaturated soils are commented and linked to various physical parameters and properties of the soils.

Pollinator diversity and host specificity in threatened Encephalartos cycads and their implications for co‐extinction and species recovery

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The highly threatened African cycad genus Encephalartos faces severe threats such as habitat loss and poaching. In addition, the lack of sexual recruitment due to the absence of pollinators (pollinator collapse) has emerged as another major threat.

The performance of unsaturated shear strength models of silt soils using the soil water characteristics curve

Results in Engineering
Various studies have investigated soils' unsaturated shear strength properties using the modified triaxial testing machine, which is costly, and time-intensive for standard geotechnical procedures.

A pore network modeling approach to bridge void ratio‐dependent soil water retention and unsaturated hydraulic conductivity curves

Engineering Reports
In geotechnical engineering, understanding the relationship between soil permeability and deformation is essential, particularly for applications like earth dams, where compaction‐induced permeability reduction is crucial for performance optimization. In

An Archaeometric Approach to Reveal Organic Compounds via GC‐MS Analyses of Two Discovered Incense Burners at Daba Al‐Bayah

Archaeometry, EarlyView.
ABSTRACT This study focuses on two terracotta incense burners discovered in the Daba Al‐Bayah necropolis in the Musandam Peninsula (Oman), associated with an Iron Age collective tomb (LCG‐2). Through gas chromatography–mass spectrometry (GC‐MS), the organic residues preserved within these artifacts were analyzed to investigate their use and ...

Disentangling mechanisms that mediate soil fungal α and β diversity during forest secondary succession

Ecography, EarlyView.
Understanding the mechanisms controlling community diversity is a central, topic in ecology, particularly in microbial ecology. Although species pools and local assembly processes are believed to play non‐negligible roles in shaping the within‐community (α) and among‐community (β) diversity of microbial communities, their relative importance as ...
