Abstract: A device provides for delivery and control of extremely high peak-intensity femtosecond pulses of light. The device transmits pulses from a femtosecond laser to an endovascular location via a suitable optical fiber and controls the light intensity distribution at the site of surgery. The extremely high intensity enables the instantaneous ablation of material (e.g. calcified plaque) inside the blood vessel, with minimal damage to surrounding tissue.

Abstract: The present invention relates to a method for identifying a chemical structure of a wide variety of low molecular weight compounds using mass-to-charge ratio and collision cross section of fragment ions of an analyte compound. The analyte compound is ionized and fragmented, and the fragment ions are measured by a mass spectrometer with an ion mobility spectrometry measurement device. According to the present method, it does not depend on any compound class-specific characteristics or structural features, therefore enabling determinations of any classes of low molecular weight compounds, which does not limit to a specific compound class. The present invention comprises three methods which share a common data structure and s data processing method.

Abstract: Systems and methods for generating extreme ultraviolet radiation from plasma are described herein. In an embodiment, gas is provided to a gas target within a vacuum chamber. A pulse laser or a pulse laser-driven wavelength conversion system provides a beam which is focused through a lens or microscope object onto the gas target to produce plasma. A collection mirror is then used to guide an extreme ultraviolet radiation beam from the plasma to a target location.

Abstract: A cyclopropanation method includes reacting an alcohol, an ester, or an aldehyde with a sulfone in an organic solvent containing a base providing a counter cation to form a cyclopropane; and isolating the cyclopropane. When using the alcohol or ester, the organic solvent further contains a catalyst having an alcohol dehydrogenation activity.

Abstract: A system and method for fabricating a perovskite film is provided, the system including a housing for use as a CVD furnace having first and second sections coupled with first and second temperature control units, respectively. The first and second sections correspond substantially to the upstream and downstream of gases, respectively. One or more substrates are loaded in the second section and controlled by the second temperature control unit, and an evaporation unit containing an organic halide material is loaded in the first section and controlled by the first temperature control unit. Each of the substrates is pre-deposited with a metal halide material. The inside of the housing is pumped down to a low pressure.
