Control of pyrite surface chemistry in physical coal cleaning. Final report

Description: In Part I, Surface Chemistry of Coal Pyrite the mechanisms responsible for the inefficient rejection of coal pyrite were investigated using a number of experimental techniques. The test results demonstrate that the hydrophobicity of coal pyrite is related to the surface products formed during oxidation in aqueous solutions. During oxidation, a sulfur-rich surface layer is produced in near neutral pH solutions. This surface layer is composed mainly of sulfur species in the form of an iron-polysu… more

Older muons are wiser: Using time information in {mu}LCR spectroscopy

Description: For {mu}LCR with slow polarization transfer, the weak resonance signals can be strengthened by delaying the positron observation period, for pulsed and chopped muon beams. Furthermore, the sensitivity to drifts can be reduced or eliminated by using the ratios of late to early e{sup +} counts. These possibilities for using time information are discussed quantitatively.

A lower cost development path for heavy ion fusion

Description: If two features of the inertial fusion process are exploited successfully, they can lead to significantly lower costs for demonstrating the feasibility of commercial electric power production from this source of energy. First, fusion capsule ignition and burn physics is independent of reaction chamber size and hydrodynamically-equivalent capsules can be designed to perform at small yield, exactly as they do at large yield. This means that an integrated test of all power plant components and fea… more

Advanced, soluble hydroliquefaction and hydrotreating catalysts. Quarterly reports No. 10 and 11, January 1, 1993--May 30, 1993

Description: The purpose of the present program is to develop soluble analogs of surface confined catalysts that can be impregnated directly into the coal structure at low temperatures. This approach should avoid problems related to surface area dependence, a two phase (surface-liquid) reaction system and, mass transport limitations. Heteropolyanions (HPAs) offer the opportunity to develop soluble forms of surface confined catalysts. HPAs, are inexpensive, well-characterized, water soluble metal oxide clust… more

The use of computer vision and force sensing for tight tolerance assembly

Description: Computer vision and force control provide feedback for robot manipulation during the assembly of objects. Both techniques have weaknesses, but their complementary strengths enable them to work well together, achieving assembly with tight tolerances. For instance, camera resolution limits the accuracy of computer vision, but it can locate approximately where the part should be placed and is an excellent choice for coarse placement of the part. Force control senses the force induced by object con… more

The Delaney Dilemma: Regulating Pesticide Residues in Foods -- Seminar Proceedings, March 16, 1993

Description: A provision in the Federal Food, Drug, and Cosmetic Act, the Delaney Clause, appears to lower risks in the setting of tolerances for pesticide residues. It prohibits any substance from being added to processed foods if it induces cancer in man or animals. In reality, the provision created a dilemma because the zero-risk statute makes it difficult to regulate pesticides. Because of the prescription of Delaney, tolerances (legal limits) are established differently for carcinogens and non-carcinog… more
