Traditional applications of transmission electron microscopy focus on examining the microstructure or microchemistry at a specific instance in time. However, it is possible to incorporate an experimental laboratory inside the microscope that permits the evolution of processes and reactions to be followed in real time and at the spatial and spectroscopic resolution of the electron microscope. A key challenge is the design and construction of the laboratory such that it can be accommodated within the limited volume that is available. Solutions involve modification of the electron microscope column or incorporating the laboratory on the specimen rod. Significant progress has been made in laboratory design by using microlithographic and MEMs techniques to miniaturize and add functionality to the laboratories. In the near future, advances in microscope design to include full aberration correction will allow significant increase in space and resolution, and result in greatly enhanced in situ capabilities. This focus issue is dedicated to dynamic experimentation in the electron microscope and builds on previous sessions at MRS meetings and Journal of Materials Research articles. Topical Areas Focus Issue Co-Editors Submission Information Instructions for manuscript preparation and submission can be found at www.mrs.org/publications/jmr. When submitting, please be sure to select “In Situ TEM Focus Issue” as the manuscript type so that it can be routed to the Focus Issue co-editors. All manuscripts will be reviewed in a normal but expedited fashion. The top 30-40 manuscripts will appear in the special focus section of the July 2005 issue. Other manuscripts that are acceptable but cannot be included in the July 2005 issue will be scheduled for publication in a subsequent issue of JMR. Advertise in This Issue
