Imaging technique enables studies on the dynamics of nanocatalysts at unprecedented spatial, temporal resolution
(PhysOrg.com) — Tiny catalyst materials may take part in a rich variety of very fast physical and chemical processes which can now be revealed more precisely thanks to a new imaging mode for dynamic transmission electron microscopes (DTEMs) developed by US scientists.

Electrochemical studies of single-wall carbon nanotubes as nanometer-sized activators in enzyme-catalyzed reaction

Description:
Chronoamperometry based on the ”controlling-diffusion layer” concept of the convective system was used to assay the activity of lactate dehydrogenase (LDH) on a bare glassy carbon (GC) electrode and a GC electrode modified by a single-wall carbon nanotube (SWNT) film. The effects of lanthanum ion, oxalic acid, and nicotine on the LDH activity were monitored. Analysis of the experimental results revealed that the single-wall carbon nanotubes could markedly increase the activity of LDH. The activation and inhibition were characterized by three quantities: the real initial reaction rate (V”0) and the maximum reaction rate (V”m”a”x) of the enzyme-catalyzed reaction and the Michaelis-Menten constant (K”m). Tapping mode atomic force microscopy (AFM) images and the Raman spectra unambiguously demonstrated that the single-wall carbon nanotubes could interact with the enzyme LDH while the SWNT-modified electrode was under the potential control. In this case, the activation of SWNT was attributed to the interaction of SWNTs with the enzyme.

Research in Science and Technology Studies, Volume 13: Knowledge and Technology Transfer

Product Description
Hardbound. Volume 13 of Knowledge and Society documents the various ways in which knowledge and technology transfer happen in practice. In reporting on the travel of thoughts and things, the authors in the volume undermine commonly held ideas about technology transfer. Their story shows how the process of transfer transforms and reshapes the object that travels. More importantly, they show how the travel of knowledge and technology results in new socio-technical arrangements, as well as in new socio-technical objects.

These stories also relate how the authors themselves take part in achieving such processes of transfer and transformation. As anthropologists, consultants, and science studies researchers we do not stand outside the transfers that we describe. The volume is, therefore, a commentary not only on the practice of knowledge and technology transfer, but also on the practice of observation and intervention.
