Title:Atomic Scale Simulations of Manufacturing Processes and Tribology

Abstract:

Molecular Dynamics (MD) simulation is an extremely powerful technique for investigating atomic phenomenon. Almost all physical phenomena when considered at the fundamental level can be attributed, directly or indirectly, to the forces acting between the atoms that constitute the material. Atomic or molecular dynamics (MD) simulations are playing an increasing important role in the fields of materials science, physics, chemistry, tribology, engineering, biology to name some. This is because there is really no alternate approach to MD simulation capable of handling such broad ranging problems at the required level of details, namely, atomistic level. MD simulations are providing new data and exciting insights into ultraprecision machining that cannot be obtained readily in any other way - theory or experiment. In this presentation some examples of MD simulation of nanometric cutting and tribology will be presented.

Title:Widely Tunable Mid-IR Lasers and Their Use in Molecular Spectroscopy

Abstract:

Mid-infrared lasers made from IV-VI compound semiconductors exhibit tuning ranges of over 200 cm-1. In addition to allowing detection of a variety of molecular species with a single laser, such wide tunability enables detection of large molecules with broad absorption bands. This seminar will describe results from detailed measurements of IV-VI diode laser emission obtained using an automated Fourier transform infrared (FTIR) spectrometer testing system. Single-mode emission frequencies were determined for different combinations of heat sink temperature and injection current. These data were then used to design and perform molecular spectroscopy experiments in which laser emission wavelength was modulated by either current or temperature tuning. Injection current tuning over narrow spectral regions (up to 3 cm-1) allowed detection of various small to medium sized molecules such as carbonyl fluoride, nitric! oxide, carbon disulfide, and benzene, but failed to detect larger molecules such as toluene. Temperature tuning over at least 50 cm-1, however, enabled detection of large molecules such as toluene. This new technique extends the use of mid-infrared laser spectroscopy to measurement of large molecules that do not have resolvable ro-vibrational structure. This talk will also describe new IV-VI semiconductor materials and laser fabrication methods presently under development at OU. Recent accomplishments include demonstration of above-room-temperature cw mid-IR photoluminescence from PbSrSe/PbSe multiple quantum well (MQW) structures grown by molecular beam epitaxy (MBE) and development of a new substrate removal laser fabrication technique that should enable cw laser operation at room temperature.

Abstract:

The ever-more-stringent requirements for the accurate measurement of the radiation doses absorbed by humans, and the ever-increasing complexity of the radiation environments in which humans operate, continuously drives research to develop more sensitive, versatile and cheap radiation monitoring devices and procedures. Recent advances in instrumentation, materials and the understanding of the physics of radiation-induced luminescence from solid materials has led to an expansion of capability in the radiation monitoring community.

Title:Narrow-Line Seyfert 1 Galaxies: A Key for Understanding Active Galactic Nuclei

Abstract:

About 10% of galaxies have in their central regions very luminous emission that is at least as bright as the integrated star light in the galaxy. These galaxies are called "Active Galaxies", and their brilliant nuclear emission is thought to be powered by the extraction of the gravitational potential energy of gas falling (accreting) onto a "supermassive" black hole that is between 1 million and 1 billion times the mass of our sun.

While there are many similarities among AGNs, there is also a large dispersion among their properties. But a black-hole powered system is ideally rather simple, having only a few intrinsic parameters that can control what we see: the black hole mass, the black hole spin, the orientation of the line-of-sight to the symmetry axis, and the rate of accretion onto the black hole.

Early in the 1990's, a strong correlation among properties of AGNs was discovered. The properties involved represent emission from regions on size scales spanning 106 orders of magnitude. We now think that this correlation is driven by the rate of accretion. Narrow-line Seyfert 1 galaxies (NLS1s) lie at one end of this correlation and are inferred to experience relatively high rates of accretion. NLS1s provide in a sense a lever arm for understanding this correlation and the effect of accretion rate on active galaxies in general.

In this talk, I will describe how the accretion rate paradigm explains the properties of Narrow-line Seyfert 1 galaxies, and describe some recent results of the OU NLS1 research program.

Title:Solar Neutrinos

Dr. K.S. Babu will discuss "Solar Neutrinos" partially based on

The discussion will be held Monday, October 22, 2001 at 3:30 pm in Room 110 PS II

Abstract:

Neutrinos are weakly interacting particles emitted in radioactive decays. They are produced abundantly in the solar core as products of nuclear fusion reactions. Several experiments carried out recently in deep underground laboratories on Earth have observed these solar neutrinos. This talk will review what we have learned from these experiments. Recent experiments have confirmed the "solar neutrino puzzle" that has persisted for many years. The observed flux of neutrinos on Earth is less than half of what is expected from the standard solar model. This puzzle can be explained if we suppose that neutrinos have tiny masses---contrary to the standard elementary particle physics lore that neutrinos are strictly massless. Such tiny masses will enable one type of neutrino to "oscillate" into another type and therefore remain hidden. Current status of this neutrino oscillation phenomenon will be reviewed.

Title:The Search For Extra Dimensions

Abstract:

The possibility of existence of extra spatial dimensions has been fascinating physicists for many decades. After a brief review of the history, I describe the recent theoretical ideas about the possible existence of large extra dimensions. These new theories may lead to remarkable consequences at low-energy experiments as well as to astronomical and cosmological implications, and thus open new avenues to searching for extra dimensions. More recent theoretical conjectures in the context of large extra dimensions and low-scale quantum gravity will also be discussed.

Title:The Higgs Challenge

Abstract:

The most important goal of future high energy colliders is to discover the Higgs bosons or to prove their nonexistence. In the Standard Model, one Higgs boson provides the mechanism by which elementary particles acquire mass. In the extensions of the Standard Model there are more Higgs bosons. I will briefly review the triumph of gauge symmetries from quantum electrodynamics to the Standard Model. Then, I will discuss the strategies to search for Higgs bosons of the Standard Model and the Minimal Supersymmetric Standard Model at the Fermilab Tevatron Collider, and the CERN Large Hadron Collider (LHC). In addition, I will discuss Higgs bosons in supergravity unified models and future challenges for particle physics.

Title:Quartz Crystals vs. Their Environment:
Time Bases or Sensors?
(Keeping The World On Time and Your Tanks Full of Gas)

Abstract:

Keeping accurate time in the presence of acceleration and temperature changes has been a problem for centuries. This talk starts with a review of the longitude problem for sailors in the 18th century and the novel solution provided by John Harrison. Some of the inventions he developed to provide a stable frequency source in a harsh environment have parallels in modern quartz crystal oscillators.

Modern telecommunications applications require performance standards for quartz crystals that are far above those of 18th century clocks. Performance has improved over recent years through extensive research on how to reduce quartz crystal reactions to environmental influences such as acceleration, force, and temperature transients, as well as to a host of manufacturing process variations. Some recent accomplishments and remaining challenges in the frequency control field will be presented.

During research on environmental influences, it became clear that instead of minimizing the influence of certain environmental effects, it was possible to maximize the influence. The field of quartz crystal sensors emerged. Examples that will be presented include high precision temperature and pressure transducers. These sensor applications are used in a variety of situations ranging from benign laboratory environments to the hostile environments at the bottom of an oil well.

The talk will conclude with a brief description of reliable oscillator circuitry used at temperatures as high as 225 °C.

Title:Limits and Limitations from Casimir Force Measurements

Abstract:

The archetypal Casimir force leads to an attractive force between two uncharged parallel metal plates placed in vacuum. The calculation of the exact value of this force is non-trivial as there are corrections due to the skin depth of the metal (conductivity correction), the smoothness of the metal surface (roughness correction) and the thermal photons that are present (temperature correction). The last correction is even controversial. Nevertheless the Casimir force measurements place some of the best limits, at some distance ranges, on the existence of exotic particles and extra dimensions that are hypothesized by modern unification theories.

Title:Shedding New Light on Protein Folding

Abstract:

To catch a glimpse of the complete molecular picture of a protein folding reaction is one of the major challenges for protein biophysicists and chemists. A central problem lies in clarification of the early folding events which occur within a few milliseconds and are un-resolvable in the past with conventional stopped-flow systems. In our laboratory, we have developed a rapid solution mixer with a dead-time of 100 microseconds, which is more than one order of magnitude faster than that of a stopped-flow instrument. With this state-of-the-art sub-millisecond mixer, combined with resonance Raman and infrared spectroscopy, we have resolved the folding reaction of cytochrome c into two phases. In the first phase, the conformational space is dramatically reduced through a kinetically controlled rapid condensation of the polypeptide chain without fine-tuning of the protein structure. It is followed by a second phase in which the secondary structure is formed and the tertiary structure is reached through a thermodynamically controlled reaction. This biphasic mechanism guarantees that the protein folds into its unique native conformation with high efficiency and fidelity.

Abstract:

Optical whispering-gallery modes of fused-silica microspheres have resonant frequencies that tune with temperature and they also have transverse profiles with evanescent components outside the sphere. These properties, in conjunction with the very high quality factors of these modes, are exploited in making sensitive measurements of the thermal conductivity and optical absorption coefficient of the surrounding medium. Novel methods for measuring thermal accommodation coefficients, trace-gas density, and chemical concentration in solution will be presented. Several related investigations, both fundamental and applied, will also be described.
