Influence of Anion and Cation Structure of Ionic Liquids on Carboxylic Acids Extraction
Frontiers in Chemistry, 2019 A recently proposed new mechanism and a model of reactive extraction of carboxylic acids by hydrophobic ionic liquids (ILs) was tested on five systems from published as well as from new equilibrium data on liquid-liquid extraction of butyric and lactic ...

Activity and Process Stability of Purified Green Pepper (Capsicum annuum) Pectin Methylesterase [PDF]
, 2004 Pectin methylesterase (PME) from green bell peppers (Capsicum annuum) was extracted and purified by affinity chromatography on a CNBr-Sepharose-PMEI column. A single protein peak with pectin methylesterase activity was observed.

Non-perturbative renormalization constants on the lattice from flavour non-singlet Ward identities [PDF]
, 1997 By imposing axial and vector Ward identities for flavour-non-singlet currents, we estimate in the quenched approximation the non-perturbative values of combinations of improvement coefficients, which appear in the expansion around the massless case of ...

Efficient construction of linear models in materials modeling and applications to force constant expansions [PDF]
, 2020 Linear models, such as force constant (FC) and cluster expansions, play a key role in physics and materials science. While they can in principle be parametrized using regression and feature selection approaches, the convergence behavior of these ...
