What is STIP?

The U.S. Department of Energy (DOE) Scientific and Technical Information Program (STIP) is a collaboration from across the DOE complex working to ensure that the results of DOE-funded research and development (R&D) and other science and technology activities are identified, disseminated, and preserved.

Why We're Here

STIP members, led by the DOE Office of Scientific and Technical Information (OSTI), work together to increase the availability and transparency of various types of scientific and technical information (STI).  This site provides background, guidance, and more to support the management and preservation of DOE-funded R&D results now and in the future.

Advanced Coal Conversion Process Demonstration: A DOE Assessment The objective of this project was to demonstrate a process for upgrading subbituminous coal by reducing its moisture and sulfur content and increasing its heating value using the Advanced Coal Conversion Process (ACCP) unit. The ACCP unit, with a capacity of 68.3 tons of feed coal per hour (two... Author(s): National Energy Technology Laboratory
Modal Testing Repeatability of a Population of Spherical Shells In this study, we investigated the variability in modal frequencies obtained from testing a set of hollow, almost spherical marine floats. We investigated four sources of variability: unit-to-unit variability, operator-to-operator variability, test repetition, and accelerometer placement. Because...

Dimensional Changes in Uranium Under Thermal Cycling Uranium undergoes permanent dimensional changes when thermal cycled in the alpha-temperature range without passing through any phase transformations. This deformation is attributed to the anisotropy of thermal expansion inherent in noncubic metals. Alpha uranium, which is orthorhombic, is... Author(s): Kelman, L. R. [Argonne National Lab.

SEPARATION OF OVERLAPPED ELECTROCHEMICAL PEAKS USING THE KALMAN FILTER A major limitation in the use of electrochemical techniques for the quantitative analysis of mixtures is the difficulty of resolving overlapped peaks. This problem is further complicated by the low signal-to-noise ratios often encountered in trace analysis and by the use of electrochemical... Author(s): Brown, T. F.; Brown, S. D.
Vertically Aligned Carbon Nanofiber based Biosensor Platform for Glucose Sensor Vertically aligned carbon nanofibers (VACNFs) have recently become an important tool for biosensor design. Carbon nanofibers (CNF) have excellent conductive and structural properties with many irregularities and defect sites in addition to exposed carboxyl groups throughout their surfaces. These...

Intersubunit communication in the dihydroorotase-aspartate transcarbamoylase complex of <i>Aquifex aeolicus</i>: Intersubunit... Aspartate transcarbamoylase and dihydroorotase, enzymes that catalyze the second and third step in de novo pyrimidine biosynthesis, are associated in dodecameric complexes in Aquifex aeolicus and many other organisms. The architecture of the dodecamer is ideally suited to channel the intermediate,...
