“…However, neither this paper nor preceding proceedings articles − that described the use of SXPHFA provided the synthetic procedures or characterization. A series of subsequent proceedings papers, such as Polymer Preprints or PMSE Preprints , provided synthetic methods and characterization for various hydrogen-bond polymers prepared by this group − and described polycarbosilanes with hexafluoroalcohol groups derived from the reaction of hexafluoroacetone with alkenyl-substituted linear polycarbosilanes (isolated as yellow oils). , One of these, PMSFA, is also shown in Scheme .

Irvine, he joined the Naval Research Laboratory in 1984, moving to PNNL in 1992. He spent a sabbatical at the Scripps Research Institute prior to joining PNNL. His research has focused on chemically interactive polymers and nanomaterials, chemical vapor sensors, radiochemical separations and sensing, and bioanalytical fluidics for biothreat detection. His work integrates aspects of the chemical sciences, material sciences, and measurement sciences into new microanalytical principles, methods, and systems. He is noted for developing a rational approach to understanding vapor sorption and polymer design as it relates to chemical detection with polymer-coated sensors. He has published over 100 papers in peer-reviewed journals and numerous book chapters and is author or coauthor on over a dozen patents, several of which have been licensed. He received an R&D 100 Award in 2004 for his work in developing a rationally designed polymer for chemical threat detection and an American Chemical Society Regional Industrial Innovation Award in 2007.

Hyperbranched polymers (HPs) are a subclass of dendritic polymers, having globular and highly branched structure, containing a number of functional groups emerging from a core. The core contains more than two functional sites where the growing branches are connected, resulting in the formation of a 3D macromolecule comprising a large number of peripheral groups. Their versatile properties and facile structural modifications have attracted considerable attention of researchers. HPs have been used in various applications such as coatings, drug delivery, nanotechnology, additives, sensors, solar cells, an so forth. Thus, this review emphasizes recent structural modifications of HPs that result in enhancement of existing or newly emerging properties. In addition, these modifications have broadened the use of HPs in various advanced technologies such as biological applications, storage devices, energy convertors, catalysis, and so forth, which have not been covered in earlier reviews. Furthermore, this article discusses the limitations associated with their fabrication and application in various fields.

Detection of explosives vapors is an extremely difficult task. The sensitivity of currently constructed detectors is often insufficient. The paper presents a description of an explosive vapors concentrator that improves the detection limit of some explosives detectors. These detectors have been developed at the Institute of Optoelectronics. The concentrator is especially dedicated to operate with nitrogen oxide detectors. Preliminary measurements show that using the concentrator, the recorded amount of nitrogen dioxide released from a 0.5 ng sample of TNT increases by a factor of approx. 20. In the concentrator an induction heater is applied. Thanks to this and because of the miniaturization of the container with an adsorbing material (approx. 1 cm 3 ), an extremely high rate of temperature growth is achieved (up to 500 °C within approx. 25 s). The concentration process is controlled by a microcontroller. Compact construction and battery power supply provide a possibility of using the concentrator as a portable device.
