THE REACTIONS OF (+)-2- AND (+)-3-CARENES WITH THE RETENTION OF THE BICYCLIC FRAMEWORK [PDF]
Chemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2010 Carane-type compounds have attracted attention in recent years due to their practical importance. This review is focused on describing the developments in the synthesis of trimethylbicyclo[4.1.0]heptanes and their unsaturated analogues from ...

Langmuir Adsorption on Fractal Surfaces
Adsorption Science & Technology, 2015 We developed two new methods for analyzing the fractal characteristics of adsorbents. In the first method, the fractal dimension of the adsorbent is determined based on the Hurst index (H) calculated for the random process of development of the Langmuir ...

Partition Coefficients of Chlorobenzenes in Heptane–Water and Heptane–Acetonitrile Systems [PDF]
Bulletin of the Chemical Society of Japan, 1982 Abstract Partition coefficients (KD) of benzene and 11 chloro derivatives of benzene were determined at 25 °C in two liquid-liquid partition systems: heptane/water and heptane/acetonitrile. Increase of KD with increase of the numbers of Cl atoms in the solute is discussed in terms of surface and cohesive energies. The small difference in

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes
Advanced Materials Technologies, EarlyView.We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

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 ...
