Chemists in academic institutions utilize a variety of resources and strategies to remain current and to track scholarly information, patents, and news. To explore how chemists in academic institutions remain current, librarians at four Canadian university institutions surveyed 231 and interviewed 14 chemistry faculty, staff, and graduate students on their information seeking behaviors and attitudes. According to survey results, a minority of chemists (13.9 percent) acknowledged that they were successfully keeping up to date, while 50.6 percent indicated that they were somewhat successful. However, a significant number of chemists (35.5 percent) indicated that they were unsuccessful and could do better in remaining current with information. Investigators analyzing focus group data identified three emergent themes related to remaining current: (1) there is “too much information – and not enough time.” No single information seeking strategy works; (2) “patents are important – but
messy.” Chemists find themselves largely suspicious about the value and credibility of patents; and (3) chemists “could do
better” in keeping up to date with new and emerging technologies. Chemists continue to be open to new tools and resources
yet readily acknowledge that they are too often not sure which information seeking behaviors, resources, or strategies work
best. This study helps to shed light on opportunities to identify and meet chemists’ evolving information needs.

Handling chemicals that require specific safety precautions and protections generates the need for hazardous waste removal and transportation costs. With the growing effort to reduce both cost per analysis and the environmental footprint of research, we report an effective alternative to the widely used methanol/acetic acid gel fixation solution. 1.0 M citric acid dissolved in 5% acetic acid (C3A) provides comparable results following both SDS-PAGE and two-dimensional gel electrophoresis, while also eliminating waste removal costs. •Citric acid dissolved in acetic acid replaces current gel fixative solution.•Cost per analysis is reduced and hazardous waste removal costs eliminated.•Environmental footprint of research is reduced.

cis-Diene diol obtained from the microbial oxidation of bromobenzene was used as a substrate for the chemoenzymatic acetylation and epoxidation with lipases. The model studies showed that the regiochemistry of the acetylation is solvent-dependent. The chemoenzymatic epoxidation followed the expected regiochemistry when compared to the chemical epoxidation with m-CPBA, but with the unexpected formation of bromoconduritol-C, an important intermediate whose electrochemical reduction led to the synthesis of (-)-conduritol-C. Experimental and spectral data are provided for all new compounds.
