Using Metadynamics to Reveal Extractant Conformational Free Energy Landscapes [PDF]

open access: yesarXiv, 2023
Understanding the impact of extractant functionalization in solvent extraction is essential to guide the development of better separations processes. Traditionally, computational extractant design uses electronic structure calculations to determine the metal binding energy of the lowest energy state.

Phenolics extraction from sweet potato peels: modelling and optimization by response surface modelling and artificial neural network [PDF]

open access: yes, 2016
Sweet potato peels (SPP) are a major waste generated during root processing and currently have little commercial value. Phenolics with free radical scavenging activity from SPP may represent a possible added-value product for the food industry.

Polymeric Assembly of Gluten Proteins in an Aqueous Ethanol Solvent [PDF]

open access: yesJ. Phys. Chem. B 2014, 118, 11065, 2014
The supramolecular organization of wheat gluten proteins is largely unknown due to the intrinsic complexity of this family of proteins and their insolubility in water. We fractionate gluten in a water/ethanol (50/50 v/v) and obtain a protein extract which is depleted in gliadin, the monomeric part of wheat gluten proteins, and enriched in glutenin, the

Mass Transfer Performance Comparison between Conventional Solvent Extraction and Supported Liquid Membrane with Strip Dispersion for Indium Recovery from Waste Stream

open access: yesChemical Engineering Transactions, 2022
Solvent extraction is one of the most popular methods to recovery indium from wastewater. Multistage operation of conventional solvent extraction requires many extraction and stripping stages which leads to large foot print requirement and large amount ...

Nanoextraction based on surface nanodroplets for chemical preconcentration and determination [PDF]

open access: yes, 2022
Liquid-liquid extraction based on surface nanodroplets, namely nanoextraction, can continuously extract and enrich target analytes from the flow of a sample solution. This sample preconcentration technique is easy to operate in a continuous flow system with low organic solvent consumption and a high enrichment factor. In this review, the evolution from

Ultrasound increases the aqueous extraction of phenolic compounds with high antioxidant activity from olive pomace [PDF]

open access: yes, 2018
Olive pomace is a waste produced by the olive oil industry in massive quantities each year. Disposal of olive pomace is difficult due to high concentrations of phenolic compounds, which is an environmental concern.

The dual nature of TDC – bridging dendritic and T cells in immunity

open access: yesFEBS Letters, EarlyView.
TDC are hematopoietic cells combining dendritic and T cell features. They reach secondary lymphoid organs (SLOs) and peripheral organs (liver and lungs) after FLT3‐dependent development in the bone marrow and maturation in the thymus. TDC are activated and enriched in SLOs upon viral infection, suggesting that they might play unique immune roles, since

Dissolution Dynamics of a Binary Switchable Hydrophilicty Solvent -- Polymer Drop into an Acidic Aqueous Phase [PDF]

open access: yesarXiv, 2022
Switchable hydrophilicity solvents (SHSs) are solvents defined by their ability to switch from their hydrophobic form to a hydrophilic form when put in contact with an acidic trigger such as $CO_2$. As a consequence, SHSs qualify as promising alternatives to volatile organic compounds during the industrial solvent extraction processes, as greener and ...
