A Review of Basic Concepts in Comprehensive Two-Dimensional Gas Chromatography [PDF]

open access: yesJournal of Chromatographic Science, 2002
The technique of comprehensive two-dimensional gas chromatography (GCxGC) is reviewed. A description of technical aspects of the method illustrates how the GCxGC result is achieved through the use of dual-coupled columns and the modulation of capillary chromatographic peaks. This review presents an expanded section dealing with the relationship between

Genetically Programmed Shape‐Morphing of Engineered Living Materials

open access: yesAdvanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with
