TL;DR: In this article, the removal of heavy metal from solutions using biosorption in cork powder is described, along with the effect of different variables, such as the solid-liquid ratio, temperature and pH on the removal efficiency of the metals.

TL;DR: In this article, the authors analyze the longevity of foreign entrants explicitly considering two possible ways of exit: firm closure and capital divestiture, and find that entry and post-entry strategies affect the lifetime of firms and of foreign equity holdings, but in different manners.
Abstract: We analyze the longevity of foreign entrants explicitly considering two possible ways of exit: firm closure and capital divestiture. We find that entry and post-entry strategies affect the longevity of firms and of foreign equity holdings, but in different manners. While the ownership arrangements and organizational structure affect the likelihood of divestment, they exert no significant effect upon closure. The entry mode exerts opposite effects on the two modes of exit, greenfield entrants being more likely to shutdown, but less likely to be divested. Only human capital affects closure and divestment in the same manner. Firms with large endowments of human capital are less likely to exit, irrespective of the exit mode considered.

TL;DR: The features of the solid-liquid phase transition were analyzed, namely the glass transition temperature and the heat capacity jump associated with the transition from the non-equilibrium glass to the metastable supercooled liquid.
Abstract: More than 50 ionic liquids were prepared by using imidazolium, quaternary ammonium, and guanidinium cations and various anions. In these series, different cationic structures such as 1-benzyl-3-methylimidazolium [Bzmim]+, 1,3-dibenzylimidazolium [BzmiBz]+, 1-octyl-3-methylimidazolium [C8mim]+, 1-decyl-3-methylimidazolium [C10mim]+, tricapryl-methylammonium [Aliquat]+, benzyltriethylammonium [BzTEA]+, phenyltrimethylammonium [PhTMA]+, and dimethyldihexylguanidinium [DMG]+ were combined with anions, p-toluenesulfonate [TSA](-), dicyanoamide [DCA]-, saccharine (2-sulfobenzoic acid imide sodium salt) [SAC]-, trifluoroacetate [TFA]-, bis(trifluoromethanesulfonyl)imide [Tf2N]-, trifluoromethanesulfonate [TfO]-, and thiocyanate [SCN]-. Important physical data for these ionic liquids are collated, namely solubility in common solvents, viscosity, density, melting point and water content. Apart from the viscosity, the Newtonian and non-Newtonian behavior of these ionic liquids is also disclosed. Stability of these ionic liquids under thermal, basic, acidic, nucleophilic, and oxidative conditions was also studied. The features of the solid-liquid phase transition were analyzed, namely the glass transition temperature and the heat capacity jump associated with the transition from the non-equilibrium glass to the metastable supercooled liquid. A degradation temperature of each ionic liquid was also determined. Comparisons of the properties of various ionic liquids were made.
