“…The maximum density of FT‐Man 1 on the V2 surface was estimated by critical aggregation concentration (CAC) measurements (Figure 3 b and Figures S5 and S6, Supporting Information) 13. Thus, an aqueous solution of 1 shows a CAC value of 19.1±1.4 m M , which increased by 5.0±1.9 m M to 24.1±1.3 m M when the same experiment was performed in a solution of V1 (1.0 m M for F8K ).…”

The calcination of magnesite and dolomite is a state of the art technology step in minerals processing. The concomitantly produced carbon dioxide (CO2) is released into the flue gas, with all its negative effects on the global carbon balance. Reductive calcination of magnesite and dolomite to carbon monoxide (CO) and methane would open a window to reuse CO2 and produce value‐added carbonaceous products. The conversion of more than 70 % of the CO2 emitted during reductive calcination of the magnesite content of a mixed magnesite/dolomite (1:1 mol/mol) to CO at moderate temperature is feasible without admixture of catalyst.

“…[13] Thus, an aqueous solution of 1 shows a CAC value of 19.1 AE1.4 mm, which increased by 5.0 AE 1.9 mm to 24.1 AE 1.3 mm when the same experiment was performed in a solution of V1 (1.0 mm for F8K). We ascribe the CAC increase to the loss of 1 from the aqueous solution because of adsorption on V1, and hence conclude that V1 adsorbs up to five molecules of 1 per F8K.…”

Ligand display on self-assembled nanostructures is an important tool in generating bioactive materials. Here, we demonstrate the display of sugar and biotin molecules on sub-100 nm-sized capsules with a high surface coverage, which was achieved by the use of noncovalent fluorous interactions between a fluorous-tagged ligand molecule and a fullerene vesicle covered with fluorous chains. Even after the high-density ligand display and protein binding, the vesicle stably maintains its spherical structure because the fluorous binding of the sugar does not affect the structural integrity of the vesicle that originates from strong fullerene-fullerene interactions.

73(4) A marked decrease in the rates of all these reactions is observed as the carbon chain became longer (from 6 to 10 carbon atoms). This is postulated to be due to steric hindrance.(5) The rate of the initial reaction between the olefin and the acid to form the monoalkyl sulphate exhibits a dependence upon the speed of stirring indicating that this reaction was at some stage heterogeneous.(6) On the basis of these results it is possible to select conditions for the accurate measurement of the heat evolved during the formation of a monoalkyl sulphate from an a-olefin and aqueous sulphuric acid. The conditions are selected on the basis of a maximum yield of monoalkyl sulphate coupled with a convenient rate of reaction. Hexene-1 appeared to be the most suitable olefin for the purpose: higher molecular weight members when reacted with 79.57% acid reached not only a lower maximum yield of monoalkyl sulphate, but also had inconveniently slow rates of reaction. The conditions shown in Table I (j) were finally selected as being the most suitable for two reasons: (1) under these conditions the maximum percentage yields of monoalkyl sulphate were achieved; (2) these conditions enabled an ice-calorimeter to be used, for by this technique the effect of the consecutive hydrolysis reaction could be estimated.l and the Dept. of Physical Chemistry in this University for helpful advice.Surface tension, interfacial tension and wetting, emdsifying, foaming, and suspension characteristics of ionic and non-ionic surfactant solutions have been determined and evaluated in absence, and in presence, of electrolytes and non-ionogenic additives. Considerable insight has been gained about the factors governing the surface and bulk properties of surfactant solutions and as regards how these are influenced by additives.
