The invention relates in various embodiments to a composite useful as e.g. a medical implant device, and a method of treating fouling, including biofouling as may occur on an implant. The composite comprises a matrix phase and a patterned phase that comprises an energetically activatable wire intermixed with the matrix phase, the wire when energetically activated, which includes thermal activation, causes modification of at least a portion of the matrix phase to treat fouling that might otherwise occur. The method of treating biofouling may be practiced on a patent while the medical implant of the invention is in situ.

Local thermal actuation of material surfaces via micro- and nanowire heating for the prevention of cellular attachment and biological fouling

A vapor particle separator including a temperature controlled chamber for desorbing vapors from the particulates of an exhaust gas and a separation chamber including a micro porous membrane. The micro porous membrane provides an interface between at least one particle passageway and at least one vapor passageway through the separation chamber. The particle passageway extends from an entrance to the separation chamber to a particle exit from the separation chamber. The vapor passageway extends from the micro-porous membrane to a vapor exit from the separation chamber that is separate from the particle exit from the separation chamber.

Membrane based apparatus for measurement of volatile particles

Apparatus for detecting an electronegative species comprises an analysis chamber, an inlet communicating with the analysis chamber for admitting a sample containing the electronegative species and an ionizable component, a radioactive source within the analysis chamber for emitting radioactive energy for ionizing a component of the sample, a proportional electron detector within the analysis chamber for detecting electrons emitted from the ionized component, and a circuit for measuring the electrons and determining the presence of the electronegative species by detecting a reduction in the number of available electrons due to capture of electrons by the electronegative species.

A method for analyzing a gaseous electronegative species comprises the steps of providing an analysis chamber; providing an electric field of known potential within the analysis chamber; admitting into the analysis chamber a gaseous sample containing the gaseous electronegative species; providing a pulse of free electrons within the electric field so that the pulse of free electrons interacts with the gaseous electronegative species so that a swarm of electrically charged particles is produced within the electric field; and, measuring the mobility of the electrically charged particles within the electric field.
