Curatives and their resulting thermosets and other crosslinked polymers can reduce thermal expansion mismatch between an encapsulant and objects that are encapsulated. This can be accomplished by incorporating a negative CTE moiety into the thermoset resin or polymer backbone. The negative CTE moiety can be a thermal contractile unit that shrinks as a result of thermally induced conversion from a twist-boat to chair or cis/trans isomerization upon heating. Beyond CTE matching, other potential uses for these crosslinked polymers and thermosets include passive energy generation, energy absorption at high strain rates, mechanophores, actuators, and piezoelectric applications.

Crosslinked polymers with tunable coefficients of thermal expansion

The present invention relates to encapsulated microfluidic packages and methods thereof. In particular embodiments, the package includes a device, a cradle configured to support the device, and a lid having a bonding surface configured to provide a fluidic seal between itself and the device and/or cradle. Other package configurations, as well as methods for making such fluidic seals, are described herein.

Viruses and other bioagents are of high medical and biodefense concern and their detection at concentrations well below the threshold necessary to cause health hazards continues to be a challenge with respect to sensitivity, specificity, and selectivity. Ideally, assays for accurate and real time detection of viral agents and other bioagents would not necessitate any pre-processing of the analyte, which would make them applicable for example to bodily fluids (blood, sputum) and man-made as well as naturally occurring bodies of water (pools, rivers). We describe herein a robust biosensor that combines the sensitivity of surface acoustic waves (SAW) generated at a frequency of 325 MHz with the specificity provided by antibodies and other ligands for the detection of viral agents. In preferred embodiments, a lithium tantalate based SAW transducer with silicon dioxide waveguide sensor platform featuring three test and one reference delay lines was used to adsorb antibodies directed against Coxsackie virus B4 or the negative-stranded category A bioagent Sin Nombre virus (SNV), a member of the genus Hantavirus, family Bunyaviridae, negative-stranded RNA viruses. Rapid detection (within seconds) of increasing concentrations of viral particles was linear over a range of order of magnitude for both viruses, although the sensor was approximately 50&#xd7;10-fold more sensitive for the detection of SNV. For both pathogens, the sensor's selectivity for its target was not compromised by the presence of confounding Herpes Simplex virus type 1. The biosensor was able to detect SNV at doses lower than the load of virus typically found in a human patient suffering from hantavirus cardiopulmonary syndrome (HCPS). Further, in a proof-of-principle real world application, the SAW biosensor was capable of selectively detecting SNV agents in complex solutions, such as naturally occurring bodies of water (river, sewage effluent) without analyte pre-processing.

The present invention relates to functionalized polymers useful for coating surfaces, such as the internal bore of a column. In particular embodiments, such functionalized polymers provide a selective stationary phase useful for separating and detecting organophosphorous agents. Methods of using such polymers are also described herein.

Functionalized coating polymers and uses thereof

A membrane assembly is provided. The membrane assembly includes a non-metallic, porous substrate. A graphene oxide membrane is formed over the non-metallic, porous substrate. A chemical linker interface covalently binds the graphene oxide membrane to the non-metallic, porous substrate.

Filtration membranes

The various technologies presented herein relate to formation of carbon micromechanical systems (CMEMS), wherein the CMEMS comprise multiple layers of carbon structures and are formed using a plurality of photoresist precursors that are processed to form carbon. The various embodiments can be utilized in producing a plurality of CMEMS with full production level fabrication, e.g., 6 inch wafers can be processed. A pyrolyzed layer of carbon is lithographically defined after pyrolysis, wherein the post-pyrolysis etch process can produce carbon structures having repeatable and accurate device geometries, with straight sidewalls. A sacrificial layer can be applied to facilitate separation of a first carbon layer from a second carbon layer, wherein, upon pyrolysis to form the second carbon layer and lithography thereof, the sacrificial layer is removed to form a CMEMS comprising a first carbon layer (e.g., comprising bottom contacts) located beneath a second carbon layer (e.g., a mechanical layer).

Fabrication of multilayered carbon MEMS devices

Various technologies presented herein relate to forming one or more heat dissipating structures (e.g., heat spreaders and/or heat sinks) on a substrate, wherein the substrate forms part of an electronic component. The heat dissipating structures are formed from graphene, with advantage being taken of the high thermal conductivity of graphene. The graphene (e.g., in flake form) is attached to a diazonium molecule, and further, the diazonium molecule is utilized to attach the graphene to material forming the substrate. A surface of the substrate is treated to comprise oxide-containing regions and also oxide-free regions having underlying silicon exposed. The diazonium molecule attaches to the oxide-free regions, wherein the diazonium molecule bonds (e.g., covalently) to the exposed silicon. Attachment of the diazonium plus graphene molecule is optionally repeated to enable formation of a heat dissipating structure of a required height.

Graphene heat dissipating structure

A patterned graphene or graphitic body is produced by providing a three-dimensionally patterned carbonaceous body; coating the body with a catalytic metal whereby is formed a coating having an inner surface proximal the body and an outer surface distal the body; and annealing the coated body under time and temperature conditions effective to form a graphene or graphitic layer on the outer surface of the catalytic metal coating.

A purification method that uses ion-selective ceramics to electrochemically filter waste products from a molten salt. The electrochemical method uses ion-conducting ceramics that are selective for the molten salt cations desired in the final purified melt, and selective against any contaminant ions. The method can be integrated into a slightly modified version of the electrochemical framework currently used in pyroprocessing of nuclear wastes.

Electrochemical ion separation in molten salts

A microporous carbon scaffold is produced by lithographically patterning a carbon-containing photoresist, followed by pyrolysis of the developed resist structure. Prior to exposure, the photoresist is loaded with a nanoparticulate material. After pyrolysis, the nanonparticulate material is dispersed in, and intimately mixed with, the carbonaceous material of the scaffold, thereby yielding a carbon composite structure.
