Robert Wethman, Associate Scientific Director, has spent more than two decades at Bristol Myers Squibb working at the intersection of analytical science and manufacturing, where the discipline plays both a foundational and increasingly strategic role in pharmaceutical development. A career…
a Ring closure of the linear precursor. b–e Ring expansion polymerization. f Living ring expansion polymerization of palladacycle for the synthesis of well-defined cyclic poly(aryl isocyanide). R, R’, R1, R2 = Substituents, L = Ligand, n = Number of ligands attached to the metal…
Technology Networks Tiny magnetic probes can be used to investigate the chemical forces at work inside the pores of molecular framework compounds Until now, this had only been possible to a limited degree Developed by a team at Martin Luther…

Figure 2 shows the structure of cellulose triacetate and the IR spectra of cellulose acetate and cellulose triacetate. Note that the alcohol O-H stretch at 3484 is bigger in cellulose acetate than in the triacetate because in the triacetate more of the…
The role of the quality control (QC) department is to check the quality of a final product and, in the case of the pharmaceutical industry, there are two key aspects that the QC department will monitor: These analyses can be…
An experimental and simulation study found that two surface histidines form a proposed pendulum-like proton relay in Group A -hydrogenases, while zinc inhibits the enzyme through a specific binding site. Researchers at Ruhr University Bochum reported that a histidine-mediated, pendulum-like…
