Bench-scale synthesis of nanoscale materials

A novel flow-through hydrothermal method used to synthesize nanoscale powders is introduced by Pacific Northwest Laboratory. The process, Rapid Thermal Decomposition of precursors in Solution (RTDS), uniquely combines high-pressure and high-temperature conditions to rapidly form nanoscale particles. The RTDS process was initially demonstrated on a laboratory scale and was subsequently scaled up to accommodate production rates attractive to industry. The process is able to produce a wide variety of metal oxides and oxyhydroxides. The powders are characterized by scanning and transmission electron microscopic methods, surface-area measurements, and x-ray diffraction. Typical crystallite sizes are less than 20 nanometers, with BET surface areas ranging from 100 to 400 sq m/g. A description of the RTDS process is presented along with powder characterization results. In addition, data on the sintering of nanoscale ZrO2 produced by RTDS are included.

The levels of edit, second edition

The editorial process is analyzed, and five levels of edit are identified. These levels represent cumulative combinations of nine types of edit: Coordination, Policy, Integrity, Screening, Copy Clarification, Format, Mechanical Style, Language, and Substantive. The levels and types of edit, although developed for specific use with external reports at the Jet Propulsion Laboratory, cover the general range of technical editing, especially as it applies to an in-house technical publications organization. Each type of edit is set forth in terms of groups of actions to be performed by editor. The edit-level concept has enhanced understanding and communication among editors, authors, and publications managers concerning the specific editorial work to be done on each manuscript. It has also proved useful as a management tool for estimating and monitoring cost.

Controlled flexibility in technical editing - The levels-of-edit concept at JPL

The levels-of-edit concept, which can be used to specify the amount of editorial effort involved in the preparation of a manuscript for publication, is discussed. Nine types of editing are identified and described. These include coordination edit (preparing estimates, gathering cost data, monitoring production processes), policy edit, integrity edit (making sure that parts of a publication match in a physical or numerical sense), screening edit (ensuring that the quality of camera-ready copy is sufficient for external publication), copy clarification edit, format edit, mechanical style edit, language edit, and substantive edit (reviewing the manuscript for content coherence, emphasis, subordination and parallelism). These functions are grouped into five levels of edit. An edit-level number is assigned to each manuscript, providing a quantitative and qualitative indicator of the editing to be done which is clearly understood by authors, managers, and editors alike. In addition, clear boundaries are drawn between normal and extraordinary editing tasks. Individual organizations will group various edits in different ways to reflect their needs and priorities; the essential element of the system is unambiguous definition and coding of the types and amount of work to be done.

Creative revision - From rough draft to published paper

The process of revising a technical or scientific paper can be performed more efficiently by the people involved (author, co-author, supervisor, editor) when the revision is controlled by breaking it into a series of steps. The revision process recommended here is based on the levels-of-edit concept that resulted from a study of the technical editorial function at the Jet Propulsion Laboratory of the California Institute of Technology. Types of revision discussed are Substantive, Policy, Language, Mechanical Style, Format, Integrity, and Copy Clarification.

The levels of edit

The editorial process is analyzed, and five levels of edit are identified. These levels represent cumulative combinations of nine types of edit: (1) coordination, (2) policy, (3) integrity, (4) screening, (5) copy clarification, (6) Mechanical Style, (7) Language, and (9) substantive. The levels and types of edit, although developed for specific use with external reports at the Jet Propulsion Laboratory, cover the general range of technical editing, especially as it applies to an in-house technical publications organization. Each type of edit is set forth in terms of groups of actions to be performed by the editor. The edit-level concept has enhanced understanding and communication among editors, authors, and publications managers concerning the specific editorial work to be done on each manuscript. It has also proved useful as a management tool for estimating and monitoring cost.
