Autonomous Solar Metallurgy for High‐Purity Gold Recovery from Electronic Waste

open access: yesAdvanced Science, EarlyView.
Inspired by microbial strategies for metal uptake and biomineralization, defect‐rich copper sulfide (Cu31S16) functions as a solar metallurgical platform that unifies Au(III) capture, reduction, and self‐separation. The bioinspired design enables ultrafast gold recovery from electronic‐waste leachates and the spontaneous formation of millimeter‐scale ...

Effects of freeze-drying and use of artificial seawater on phosphorus exchange isotherms in brackish water sediments

open access: yesSN Applied Sciences, 2022
This study reports results on the estimated magnitude of changes in P sorption isotherms in clayey mud sediments when performed using (1) freeze-dried instead of fresh sediment samples and (2) artificial sea water (ASW) instead of ambient near-bottom ...

A physico-chemical model of the water vapour sorption isotherm of hardened cementitious materials

open access: yes, 2012
This paper reports on the recent development of a physico-chemical model for the water retention characteristic of porous media and its application to the prediction of water vapour sorption isotherm of cementitious materials.

Application of Kinetic and isotherm models to the Sorption of Copper (II) on to superabsorbent polymer in powder form [PDF]

open access: yes, 2014
Equlibrium sorption of the sodium polyacrylate (PANa) in powder form was studied. The Elovich model and the Pseudo-second order model both provided a high degree of correlation with the experimental data for most of the sorption process.

Programmable Guest‐Induced 5‐Phase‐Transition Topological Reconstructions of Cobalt Formate Metal–Organic Frameworks

open access: yesAdvanced Science, EarlyView.
A reversible five‐phase topological cycle is achieved in a minimalist cobalt formate metal–organic framework. The amorphous phase functions as a programmable reactive hub, selectively reconstructing into four distinct crystalline architectures through cationic templates, humidity, or CO2.

Effect of Soil Organic Matter and Humates on Adsorption and Desorption Chemistry of Iodide in an Aridisol

open access: yesJournal of Agricultural Sciences, 2020
The translocation of iodine (I) from soil to food chain is largely determined by its adsorption/desorption reaction in soils. In this study, the effects of commercial humates (HA) applied on an Aridisol and indigenous soil organic matter (SOM) on the ...

Effect of sorption isotherm type on predictions of solute mobility in soil

open access: yes, 1994
Partitioning of a species between aqueous solution and sorbed phases is commonly described as an equilibrium process and modeled by a sorption isotherm. These sorption models may be derived from the cumulative effect of many underlying specific reactions.

Ultrasound‐Activated Nanoinhibitors Blocking the Chemo‐Immune Checkpoint to Overcome Chemotherapy‐Induced Immune Resistance

open access: yesAdvanced Science, EarlyView.
A sono‐responsive chemo‐immune checkpoint nanoinhibitor (Sono‐TT8) co‐delivering TPZ chemotherapy and siXkr8 simultaneously kills tumor cells and blocks PS externalization, reversing chemotherapy‐induced immunosuppression and enhancing antitumor immunity. ABSTRACT Breast cancer features an immunosuppressive tumor microenvironment following chemotherapy
