 | A ring Ti/dye laser was purchased from Coherent Laser, model 899-21. The laser has been used in experiments involving metastable atom beam cooling. During this work the investigators developed a method of measuring laser line width that can be directly related to the fundamental quantities time and distance. Two spectra taken with the ring laser are included with this report. |

|
| This project is aimed at probing electron transfer through a single molecule sandwiched between two electrodes ("source" and "drain") in an electrolyte. The electron flow is controlled by the bias voltage between the electrodes, the separations between molecule and the electrodes as well as by a third electrode ("gate") inserted into the electrolyte. The long-term goal of this project is to develop transistors and switches ... |

| The objectives of this project are to seek a better understanding of electron transport in single molecules and to develop a molecular electronic device that can communicate with the outside world in a more practical way than the existing methods. In order to reach the objectives, we have proposed to acquire and set up a thin film fabrication system and electronic characterization equipment. |

| Theoretical and computational work was carried out to investigate the underlying physical mechanisms that cause laser induced biological damage and material stress. In order to cause damage to the absorbing material, the electromagnetic energy of the laser pulse must be converted to thermo-mechanical energy. We have developed a computational model that allows the calculation of damage resulting from a laser pulse of any duration or energy due to temperature rise, ... |

 | The thermal decomposition of BDD has been observed in a TOF- quadrupole tandem mass spectrometer system. The major ion products observed were 30, 41, 43, and 46 amu. All of the data obtained in the present study indicate that, under vacuum, BDD thermally decomposes at temperature in the range of 160- 180 degrees centigrade to provide BDA and nitric acid. The nitric acid partially decomposes to produce nitrogen dioxide. Since ... |

| The funding provided in this grant has allowed the development of a comprehensive computational model for predicting the effect that any laser pulse will have on any spherical absorbing particle. This model is based upon fundamental principles an( therefore is capable of determining all thermomechanical responses (temperature rise, shock wave, explosive vaporization) and is applicable to a wide range of materials with unprecedented accuracy. This allows the assessment of potential ... |
