Definition of the Transfer Coefficient

The transfer coefficient α is a quantity that is commonly employed in the kinetic investigation of electrode processes. An unambiguous definition of the transfer coefficient, independent of any mechanistic consideration and exclusively based on experimental data, is proposed. The cathodic transfer coefficient αc is defined as —(RT/F)(dln jc/dE), where jc is the cathodic current density corrected for any changes in the reactant concentration on the electrode surface with respect to its bulk value, E is the applied potential and R, T and F have their usual significance. The anodic transfer coefficient αa is defined similarly, by simply replacing jc with the anodic current density and the minus sign with the plus sign. This recommendation aims at clarifying and improving the definition of the transfer coefficient reported in the 3rd edition of the IUPAC “Green Book.”

Glossary of Terms Used in Medicinal Chemistry Part II

The evolution that has taken place in medicinal chemistry as a result of major advances in genomics and molecular biology has carried with it an extensive additional working vocabulary that has become both integrated and essential terminology for the medicinal chemist. Some of this augmented terminology has been adopted from the many related and interlocked scientific disciplines with which the modern medicinal chemist must be conversant, but many other terms have been introduced to define new concepts and ideas as they have arisen. In this supplementary glossary we have attempted to collate and define many of the additional terms that are now considered to be essential components of the medicinal chemist’s expanded repertoire.

Terminology of Metal-Organic Frameworks and Coordination Polymers

A set of terms, definitions and recommendations is provided for use in the classification of coordination polymers, networks and metal-organic frameworks. A hierarchical terminology is recommended where the most general term is coordination polymer. Coordination networks are a subset of coordination polymers and metal-organic frameworks (MOFs) a further subset of coordination networks. One of the criteria a MOF needs to fulfill is that it contains potential voids but no physical measurements of porosity or other properties are demanded per se. The use of topology and topology descriptors to enhance the description of crystal structures of MOFs and 3D-coordination polymers is furthermore strongly recommended.

Glossary of Terms used in Computational Drug Design, Part II

Computational drug design is a rapidly changing field that plays an increasingly important role in medicinal chemistry. Since the publication of the first glossary in 1997 (Pure Appl. Chem., 1997, Vol. 69, No. 5, pp. 1137–1152. http://dx.doi.org/10.1351/

pac199769051137), substantial changes have occurred in both medicinal chemistry and computational drug design. This has resulted in the use of many new terms and the consequent necessity to update the previous glossary. For this purpose a Working Party of eight experts was assembled. They produced explanatory definitions of more than 200 new and revised terms.
