Interactions between cadmium and lead with acidic soils: Experimental evidence of similar adsorption patterns for a wide range of metal concentrations and the implications of metal migration [PDF]

open access: yes, 2012
The importance of high- and low-affinity surface sites for cadmium and lead adsorption in typical European and Asian soils was investigated. Adsorption experiments on surface and deep horizons of acidic brown (Vosges, France) and red loess soils (Hunan ...

Complex tangents of real surfaces in complex surfaces

open access: yesDuke Mathematical Journal, 1992
Let \(M\) be a closed real surface, and let \({\mathcal M}\) be a complex manifold of complex dimension two. Let \(\pi:M\to{\mathcal M}\) be an immersion or embedding of \(M\) into \({\mathcal M}\). A point \(p\in M\) is a complex tangent if \(\pi_ *(T_ pM)\) is a complex 1-dimensional subspace of \(T_{\pi(p)}{\mathcal M}\).

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Unraveling natural aging-induced properties change of sludge-derived hydrochar and enhanced cadmium sorption site heterogeneity

open access: yesBiochar, 2022
Highlights Aged hydrochar undergoes surface oxidation, mineral complexation, and leaching. Ash content and SSA play the essential role in enhancing Cd sorption and site heterogeneity.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Magnetic Biochar–Nanoscale Zero-Valent Iron Composites for Arsenic Immobilization and Magnetically Assisted Separation From Aqueous Matrices in Mining-Impacted Environments

open access: yesDigest Journal of Nanomaterials and Biostructures
A magnetic biochar–nanoscale zero-valent iron (MBC-nZVI) composite was synthesized from pine bark via an in-situ liquid-phase reduction method to immobilize arsenic in mining-impacted soils.

Reversible aqueous Zn battery anode enabled by a stable complexation adsorbent interface

open access: yesEcoMat, 2022
Rechargeable aqueous Zn batteries (RAZBs) are highly promising for grid‐scale energy storage systems. Nevertheless, strong water molecule adsorption on Zn electrode provokes undesired corrosion reactions and electrode polarization/dendrite growth ...
