Lithium extraction from salt‐lake brines using dicationic ionic liquids: ePC‐SAFT modeling and molecular mechanisms

open access: yesAIChE Journal, EarlyView.
Abstract This work proposes a novel strategy for enhancing Li+ extraction from salt‐lake brines with the high Mg2+/Li+ ratio using dicationic ionic liquid (DIL)‐based extractants. The ternary mixture of the DIL [DOMIM][Tf2N]2, tributyl phosphate (TBP), and dichloromethane (DCM) as a diluent achieved a higher single‐stage Li+ extraction efficiency (86 ...

Regulating Multifunctional Oxygen Vacancies for Plasma‐Driven Air‐to‐Ammonia Conversion

open access: yesAngewandte Chemie, EarlyView.
High defective Fe2O3 nanoparticles on Cu synthesis by plasma introduced multifunctional oxygen vacancies achieving 100% NH3 selectivity through a plasma‐electrochemical system capable of directly reducing air to gaseous NH3. Abstract Current ammonia (NH₃) synthesis is hindered by challenges including N₂ activation, NH₃ separation and process complexity.

Designing Memristive Materials for Artificial Dynamic Intelligence

open access: yesAdvanced Intelligent Discovery, EarlyView.
Key characteristics required of memristors for realizing next‐generation computing, along with modeling approaches employed to analyze their underlying mechanisms. These modeling techniques span from the atomic scale to the array scale and cover temporal scales ranging from picoseconds to microseconds. Hardware architectures inspired by neural networks

Univalence for free [PDF]

open access: yes, 2013
We present an internalization of the 2-groupoid interpretation of the calculus of construction that allows to realize the univalence axiom, proof irrelevance and reasoning modulo. As an example, we show that in our setting, the type of Church integers is equal to the inductive type of natural numbers.

Robot‐Assisted Measurement of the Critical Micelle Concentration

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The study introduces (SIMO) smart integrator for manual operations, a robotic platform for precise, repeatable determination of (CMC) critical micelle concentration in surfactants. SIMO reduces standard deviation by 80% compared to manual methods. Surfactant, dye, and diluent selection, robotic protocols, and data handling are detailed.
