Synthesis of Anomeric Methyl Fructofuranosides and Their Separation on an Ion-exchange Resin  Erkki Nurminen, Päivi Poijärvi, Katja Koskua, and Jari Hovinen
Treatment of d-fructose with methanol in the presence of acid as a catalyst gives a mixture of methyl--d-fructopyranoside, methyl-a-D-fructofuranoside, and methyl--d- fructofuranoside, which are separated on an ion exchange column and characterized polarimetrically.

Demonstrating Encapsulation and Release: A New Take on Alginate Complexation and the Nylon Rope Trick  Andrienne C. Friedli and Inge R. Schlager
Three variations on a classroom demonstration of the encapsulation of droplets and evidence for release of the interior solution are described. The first two demonstrations mimic biocompatible applications of encapsulation. A third encapsulation exercise exploits the irreversible interfacial polymerization of diamine and diacid chloride to form membranes and illustrates the detection of diamine release from the capsule using an indicator.

A New Method To Convert the Fischer Projection of Monosaccharide to the Haworth Projection  Qing-zhi Zhang and Shen-song Zhang
The D,L-configuration of a sugar in Haworth projection can be directly determined by designating the R,S-configuration of the highest-numbered asymmetric carbon; that is, the most distant carbon from the anomeric carbon. The R-configuration at this carbon corresponds to the D-family, and S- to the L-family.
