Rediscovering Sodium Ionophores as Selective Agents for Lithium Recognition and Extraction
Angewandte Chemie, EarlyView.Long‐classified sodium ionophores unexpectedly prefer lithium and act as efficient extractants in solid–liquid extraction (SLE). Readily prepared from catechol and haloacetamides, these hosts recover hydrated LiCl from multicomponent salt mixtures via a hydration‐assisted O···Li+ binding mode, enabling scalable lithium separation with Li/Na, Li/K, and ...

Lotus leaf extract can attenuate salpingitis in laying hens by inhibiting apoptosis
Poultry Science, 2023 : This study aimed to determine whether the lotus leaf extract (LLE) had the effect of treating salpingitis in laying hens. First, the salpingitis model was established by the method of bacterial infection.

Constraints on the Neighborhood Size in LLE
IEICE Transactions on Information and Systems, 2011 Locally linear embedding (LLE) is a well-known method for nonlinear dimensionality reduction. The mathematical proof and experimental results presented in this paper show that the neighborhood sizes in LLE must be smaller than the dimensions of input data spaces, otherwise LLE would degenerate from a nonlinear method for dimensionality reduction into a

Application of the Genetic Algorithm to Calculate the Interaction Parameters for Multiphase and Multicomponent Systems [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2007 A method based on the Genetic Algorithm (GA) was developed to study the phase behavior of multicomponent and multiphase systems. Upon application of the GA to the thermodynamic models which are commonly used to study the VLE, VLLE and LLE phase ...
