Physico-mechanical and microstructural behaviour of high-water-content dredged sediment treated by vacuum preloading coupled with alkali-activated materials

Case Studies in Construction Materials
High-water-content dredged sediment (HWDS) solidification via the physico-chemical combination method (PCCM) shows potential for land reclamation. Traditional cement-lime-based PCCM demonstrates limitations of high cost and carbon emissions. Fly ash (FA),

Metagenomic analysis of rhizosphere microflora of oil-contaminated soil planted with barley and alfalfa. [PDF]

PLoS ONE, 2018
The role of rhizosphere microbial communities in the degradation of hydrocarbons remains poorly understood and is a field of active study. We used high throughput sequencing to explore the rhizosphere microbial diversity in the alfalfa and barley planted

Strength development of dredged sediment stabilized with nano-modified sulphoaluminate cement

Soils and Foundations
Sulphoaluminate cement (SAC) is considered a low-carbon and energy-saving cementitious material, compared with ordinary Portland cement. However, the stabilization efficiency and improvement measures of SAC for dredged sediment (DS) are still unclear ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...
