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 ...

Kinetic selectivity in metal-organic framework chemical sensors

open access: yesNature Communications
Selective detection of specific volatile organic compounds (VOCs) is crucial for health, safety, and environmental applications, but current sensors suffer from poor selectivity and struggle to measure specific VOCs in the presence of interfering ...

The effect of surfactant concentration, salinity, temperature, and pH on surfactant adsorption for chemical enhanced oil recovery: a review

open access: yesJournal of Petroleum Exploration and Production Technology, 2020
Enhanced oil recovery (EOR) processes have a great potential to maximize oil recovery factor of the existing reservoirs, where a significant volume of the unrecovered oil after conventional methods is targeted.

Improper Estimation of Thermodynamic Parameters in Adsorption Studies with Distribution Coefficient K D (q e/C e) or Freundlich Constant (K F): Considerations from the Derivation of Dimensionless Thermodynamic Equilibrium Constant and Suggestions

open access: yesAdsorption Science & Technology, 2022
Adsorption processes often include three important components: kinetics, isotherm, and thermodynamics. In the study of solid–liquid adsorption, “standard” thermodynamic equilibrium constant K Eq o ; dimensionless) plays an essential role in accurately ...

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

Upcycling polyethylene into closed-loop recyclable polymers through titanosilicate catalyzed C-H oxidation and in-chain heteroatom insertion

open access: yesNature Communications
Polyolefins are the most widely produced type of plastics owing to their low production cost and favorable properties. Their polymer backbone consists solely of inert C-C bonds, making them resistant and durable materials.

Removal of ibuprofen and paracetamol from water using a blend activated carbon from paper waste and avocado seeds

open access: yesGreen Analytical Chemistry
The presence of pharmaceuticals in water is a major problem worldwide. To alleviate this, this study produced carbon blends from avocado seeds and paper waste and activated them with hydrogen peroxide (H2O2), nitric acid (HNO3) and potassium permanganate

Adsorption of Methylene Blue in Water onto Activated Carbon by Surfactant Modification

open access: yes, 2020
In this paper, the enhanced adsorption of methylene blue (MB) dye ion on the activated carbon (AC) modified by three surfactants in aqueous solution was researched.

C9orf72 ALS‐causing mutations lead to mislocalization and aggregation of nucleoporin Nup107 into stress granules

open access: yesFEBS Letters, EarlyView.
Mutations in the C9orf72 gene represent the most common genetic cause of amyotrophic lateral sclerosis (ALS), a fatal neurodegenerative disease. Using patient‐derived neurons and C. elegans models, we find that the nucleoporin Nup107 is dysregulated in C9orf72‐associated ALS. Conversely, reducing Nup107 levels mitigates disease‐related changes.
