Columnist David W. Ball discusses the pioneering work of Erwin Schrodinger, whose work on wave mechanics forms the basis of the modern understanding of subatomic behavior.

First developed in the mid-1980s, matrix assisted laser desorption ionization (MALDI) added a complementary mass spectrometry ionization technique to others that were already on the market, such as electrospray ionization (ESI).

In this "Focus on Quality" column, we will look at the overall GMP changes and then ask the following question: Why has the laboratory not been included in the proposed changes?

The study of the photophysical and optoelectronic properties of a functioning conducting polymer device is complicated and is hampered by the complex nanostructure and morphology of the conducting polymer materials in these devices. Here we discuss an approach to investigate this issue in terms of bulk-heterojunction organic photovoltaic devices.

Speciation analysis has grown rapidly and has expanded to a variety of markets, including environmental, clinical, food, nutraceutical, and bioanalytical. This growth has resulted from the realization that knowing the total amount of an element does not always provide adequate information for assessing health and environmental effects, but knowing which form of the element is present presents a much more comprehensive picture.
