Spectral analysis of total suspended solids mixtures for solids composition determination
Total Suspended Solids (TSS) analysis provides an initial and very basic measure for study and characterization of water quality. The present tedious procedures used for the identification of different solids constituents present in TSS and for the classification or insight into the origins of …

Spin dynamics in solids
The work described in this thesis falls into two largely unrelated categories. Part I of the thesis reports unusually fast 13C spin diffusion in adamantane. A calculation of the 13C spin-diffusion rate from first order perturbation theory is presented and compared to the experimental data. There is …

Chemical pressures in crystalline solids
… pressure (CP) in molecules (H2 , CO2 , S8 ) and solids exhibiting all kinds of chemical interactions: covalent (graphene, diamond), ionic (alkali halides and hydrides), metals (group 1 and group 15 elements), van der Waals (solid CO2 and S8 , graphite) and hydrogen bonds (ice-I). From the …

Shock Physics in Compressible Solids
… and tensile shock waves in compressible solids, focusing on thermoelastic (TE) and thermoviscoelastic (TVE) materials with and without rheology. Shock phenomena in compressible solids are inherently complex, involving nonlinear wave interactions, dissipation mechanisms, and …

The Flow of Fluidised Solids
The design and construction of a large test rig comprising an open sloping channel along which fluidised particulate materials may flow is described. A large number of experiments have been performed in this rig, aimed at establishing the rheological properties of a bed of flowing sand under a wide …

Reactive solids under shock compression
In this dissertation chemically reactive solids, such as thermites and energy absorbing molecular materials, under shock compression are explored. To drive shock waves into target materials, an apparatus to launch and monitor laser-driven flyer-plates was developed. This was coupled to a home built …

Ultrasonic hot spots in solids
… An important example of such phenomena in solids is the mechanical initiation of explosions, which has long been speculated to result from ‘hot spot’ generation at localized microstructures in the energetic material (EM). Direct experimental evidence of such hot spots, however, is …

Robust Microporous Metalloporphyrin Framework Solids
… in its pores. No other porphyrin framework solids where catalysis occurs in the pores have been reported in the literature to date, even though this is the most often cited application for the research. Another impressive feature of PIZA-5 is that it hydroxylates cycloalkanes in a size- and …

Ion Implantation Damage in Solids
Ion induced surface smoothing and roughening processes were studied using Molecular Dynamics (MD) computer simulation. The simulations on self-ion bombarded W showed the effect of the surface on defect production and the roughening of the surface. The simulations on the CuTi, Ag and Ni with …

Mixing for Suspension of Solids
The power required to suspend several solid materials in a circular fully baffled tank was studied. A single 45 degree pitched blade impeller was used to produce downward flow. Sand, wheat straw, corn stover, activated carbon, and activated carbon-sand mixture were studied in this system. Several …

The microwave digestion of solids
Microwave ovens have been available for domestic cooking since 1956. This method of heating is very efficient compared to conventional cooking methods. As a result many applications have arisen particularly in the field of analytical chemistry. Most routine analysis of biological and chemical …

Practical electron cloaking in solids
… scattering centers from conducting electrons in solids is discussed theoretically. The wavelength of conducting electrons in solids is of the order of a few nanometers, rendering the transformation optics technique impractical in this circumstance. Instead, a method based on the expansion of …

ICP Analysis of Solids/Waste Slurries
The direct injection of solids/water slurries into an inductively coupled plasma (ICP) spectrometer offers a rapid and easy method for the analysis of major, minor, and trace elements in coal, coal ash, cements, and refractory materials. In this study aqueous slurries of 6 coals were prepared by …

Defects and Rearrangements in Disordered Solids
… from extended vibrational modes in disordered solids. This method augments particle interactions with an artificial potential that acts as a high-pass filter: it preserves small-scale structures while pushing extended vibrational modes to higher frequencies. The low-frequency modes that remain …
