Crown ethers as stabilising ligands for oxonium ions
Peter C. Junk,
New J. Chem., 2008, 32, 762
DOI: 10.1039/b800122g
Crown ethers can be used to isolate oxonium ions (H+·(H2O)n (n = 1, 2, 3, 4)). The structure and oligonuclearity of the oxonium ion depends on the hydrogen bonding acceptor properties of the immediate environment.

Michael P. Schramm, Julius Rebek and Jr.,
New J. Chem., 2008, 32, 794
DOI: 10.1039/b718595b
Two homotopic methyl groups become diastereotopic when encapsulated in a chiral hybrid assembly; remotely situated chiral centers at the base of the resorcinarene relay information through space, and these effects are shown to be a function of distance.

Ternary and quaternary co-crystals of 1,3-cis,5-cis-cyclohexanetricarboxylic acid and 4,4
-bipyridines
Balakrishna R. Bhogala and Ashwini Nangia,
New J. Chem., 2008, 32, 800

Co-crystals of 1,3,5-cyclohexanetricarboxylic acid·4,4-bipyridine1·bipyridine2 have hexagonal or square supramolecular network depending on the nature of methylene/ethene tether between the bipy groups. A self-assembly model to explain the formation of different network architectures from similar node and connector building blocks is proposed.

Pattern recognition based identification of nitrated explosives
Aravindan Ponnu, Nicola Y. Edwards and Eric V. Anslyn,
New J. Chem., 2008, 32, 848
DOI: 10.1039/b801589a
We report an effective approach for the identification of nitro explosives by the reaction of an electron-acceptor with an electron-donor with and without the addition of 
-cyclodextrin (-CD). Pattern recognition analysis was applied to analyze the data collected and it showed successful discrimination of the nitro explosives. This work represents the simplest colorimetric chemical sensor technique to be used in monitoring the range of common nitro explosives.
