Article discussing research on the correlation and prediction of partition coefficient between the gas phase and water, and the solvents dry methyl acetate, dry and wet ethyl acetate, and dry and wet butyl acetate.

Article discussing archiving web-published materials and a needs assessment of librarians, researchers, and content providers.

Article describing the life and career of Johan Gadolin. Tourist information regarding locations significant to his history is included.

Front cover of The Hexagon, featuring a painting by Beatrix Potter. In the painting, a mouse wearing glasses sits on the intake tube of a lit Bunsen burner and reads a red book. Behind this is a group of unpainted mice using chemistry equipment. "A Dream of Toasted cheese" is written to the left of the burner's flame, and a note concerning NH3 is written to the bottom left. Above these images is the title of the magazine. Above that are pictures concerning other articles. The inside cover features a table of contents, work credits, and an introductory editorial.

This article studies the hard X-ray spectral properties of 10 highly luminous radio-quiet active galactic nuclei at z = 1.3-3.2, including new XMM-Newton observations of four of these sources.

This article presents point-source catalogs for the ≈2 Ms exposure of the Chandra Deep Field-South.

Article describing the career of Robert Bunsen and the history of spectroscopy and its use in mineral analysis. The discovery of cesium and rubidium using spectroscopy on mineral water is included. In addition, the authors offer tourist information regarding locations pertinent to Bunsen and certain mineral water springs.

Article explaining the front cover of issue 3 of volume 99 of The Hexagon, which features a painting of mice around a Bunsen burner. James Marshall discusses the picture and how it relates to the history of chemistry.

Article describing the life and career of Martin Heinrich Klaproth, including his discoveries of uranium and zirconium. Tourist information regarding locations significant to his history is included.

This article presents Spitzer rest frame mid-infrared spectroscopy of 12z~2 millimeter-bright type 1 QSOs.

Article on multi-site genetic modification of monolignol biosynthesis in alfalfa (Medicago sativa) and the effects on lignin composition in specific cell types.

Article on heart rate variability characteristics in sedentary postmenopausal women following six months of exercise training.

Article on the characterization of noise in a flux qubit using macroscopic resonant tunneling between the two lowest lying states of a bistable rf SQUID. Analysis of these results indicates that the dominant source of low energy flux noise in this device is a quantum mechanical environment in thermal equilibrium.
