1 Miller, Jan D.Bubble generation in swirl flow during air-sparged hydrocyclone flotationAir-sparged hydrocyclone (ASH) flotation is a new, promising technology, and, since its conception, numerous applications have been successfully tested. Nevertheless, research and development efforts have continued to improve the technology with respect to operating conditions and design considerati...Air-sparged hydrocyclone flotation; Bubble size; Process variables1996
2 Miller, Jan D.; Lin, Chen-LuhCapillary network model for filter cake based on pore structure analysisDewatering of fine coal by continuous filtration involves filter cake formation and removal of surface moisture by drawing air through the capillaries of the cake. In order to gain a better (understanding of the complex transport phenomena that occur in the filter cake, analysis of the effect of t...Pore geometry; Transport properties; Microtomography1996
3 Jewell, PaulCirculation, salinity, and dissolved oxygen in the Cretaceous North American seawayCritical paleoceanographic problems regarding the maximum transgressive phase of the Cretaceous North American seaway have been studied with a three-dimensional ocean circulation model. Four simulations employing minimum and maximum solar insolation winds from the Cretaceous and a wide range of pre...Cretaceous North American Seaway1996
4 Miller, Jan D.; Lin, Chen-LuhFine coal washability-liberation analysis by cone-beam X-Ray microtomographyA new method based on cone-beam x-ray microtomography is described for direct determination of the three-dimensional liberation spectrum of multiphase particles 100 microns in size or less. Such a technique may provide the basis for more detailed and accurate washability analysis in fine coal chara...Spectrum; Sink-float; Density1996
5 Miller, Jan D.Hydrophobicity and elemental composition of laser-printed toner filmsLaser-printed toner films on a polymer support were treated with alkaline (NaOH) aqueous solutions at elevated temperature (80-85° C). These toner films were examined with a sessile-drop contact-angle measurement technique in order to establish the hydrophobicity of the toner surface. Also, X-ray p...Ink; Fibers; Deinking1996
6 Miller, Jan D.Interaction forces between ink particles, cellulose fibers and mineral fillers as determined by AFMRecycling of wastepaper is an important industrial activity for the conservation of our natural resources. Wastepaper is mostly generated from newspaper and office waste (from photocopiers and laser printers) [1]. One important step in wastepaper recycling is the separation of ink from cellulose...Solution; Wastepaper; Chemistry1996
7 Miller, Jan D.Mercury control in the cyanidation of gold oresThe control of mercury during gold cyanidation is of particular interest to the gold mining industry. Typically, mercury(II) is released as cyano complexes during leaching and follows gold through the solution concentration and purification step (carbon adsorption and electrowinning or zinc cementat...Gold cyanidation; solvation extraction; selective cementation1996
8 Chandran, RaviMicrostructure and thermal conductivity of thermal barrier coatings processed by plasma spray and physical vapor deposition techniquesThe temperature dependence of the thermal conductivity of multilayer coatings made by a plasma spray technique as well as some coatings made by physical vapor deposition (PVD) was investigated. The multilayer coatings consisted of a varying number of layers of AI2O3 and Zr02 stabilized by 8%Y203. Pl...Thermal barrier coatings; Multilayer coatings; Plasma spray technique1996
9 Miller, Jan D.Toner ink particle morphology in air-sparged hydrocyclone flotation deinkingA series of pulping and flotation deinking tests were performed using a pilot-scale air-sparged hydrocyclone (ASH) flotation cell and a toner ink printed furnish. Microscopy studies indicate ink particles in both the flotation accepts and rejects are relatively flat. Many of the ink particles ap...Elongation; Cyclone; Particles1996
10 Miller, Jan D.Water at interfaces - some recent experimental results from surface spectroscopyFundamental aspects of interfacial phenomena in aqueous systems are determined by the properties of interfacial water It has become evident that interfacial water must be characterized spectroscopically in order to explain the recently identified non DLVO forces observed by atomic force microscopy a...Interfacial water; Surface spectroscopy; Hydrophobic surfaces; Hydrophilic surfaces; Hydrogen bonding; FTIR/IRS; SFG; Spectroelectrochemistry; Non-DLVO forces; Atomic force microscopy1996
