Abstract: Fluorinated cyclopentene moieties and fluorinated cyclopentene functionalized silica materials are provided. The fluorinated cyclopentene functionalized silica materials include a silica material having the fluorinated cyclopentene moiety covalently bonded thereto. Exemplary silica materials include a polysilsesquioxane, a nanosilica, a microsilica, a silica gel, a silica aerogel, or combinations thereof. The fluorinated cyclopentene moieties are based on a modification of perfluorocyclopentene (i.e., 1,2,3,3,4,4,5,5-octafluoro-1-cyclopentene) by nucleophilic substitution with an appropriate nucleophile having a reactive functional group. Methods for preparing fluorinated cyclopentene moieties and the corresponding fluorinated cyclopentene functionalized silica materials are also provided.

Abstract: A beam ionization gauge (BIG) detector is disclosed for use in spectroscopy and configured to receive an analyte beam along a beam path. The BIG detector includes a filament configured to emit electrons and a grid. The grid is positioned substantially adjacent to the filament and configured to produce ions by directing the electrons to collide with the analyte beam along the beam path. A collector is positioned substantially adjacent to the grid to define the beam path therebetween and configured to detect the ions produced by the collisions of electrons with the analyte beam.

Abstract: A system for improving port isolation of a three port circulator device includes a power splitter having a power splitter input and two power splitter outputs. A first circulator has a first circulator first port, a first circulator second port, and a first circulator third port, and the first circulator first port is electrically coupled to the first of the two power splitter outputs. A second circulator has a second circulator first port, a second circulator second port, and a second circulator third port, and the second circulator first port is electrically coupled to the second of the two power splitter outputs. A first trimmer is electrically coupled to the first circulator third port and a second trimmer is electrically coupled to the second circulator third port.

Abstract: An apparatus for interconnecting a radio communication equipment connector with non-Original Equipment Manufacturer (OEM) accessories includes a pass through portion including a first connector and a second connector having the same type and an opposing gender with respect to the first connector. A conversion portion is coupled adjacent the pass through portion and is configured to electrically interface with one of the plurality of the contacts of the first connector or the second connector. The conversion portion is further configured to transmit a signal from one of the plurality of contacts of the first connector or the second connector to a non-OEM accessory. Additionally, the apparatus is configured to concurrently maintain the functionality between an OEM accessory and a radio connected thereto.
