This proposed project is concerned with the design, fabrication, and demonstration of a new class of plasmonic nanostructures for single molecule surface-enhanced Raman spectroscopy for biological and chemical sensing applications. A complete design of the plasmonic nanostructures with large local field enhancements (E/E0>100) will be formulated, and the fabrication procedures will be developed fo ...

In the past few years, there have been promising demonstrations of new approaches to short-gate (i.e., sub-nanosecond) operation of single-photon avalanche diodes (SPADs) with gating frequencies as high as 2 GHz. However, these demonstrations have had limitations, including operation at just a single fixed frequency, fairly high residual afterpulsing levels, and the lack of industrialization req ...

The chloroperoxidase enzyme from the filamentous fungus Caldariomyces fumago has applications in industrial chemical synthesis and the detection and inactivation of chemical warfare agents. Chloroperoxidase is capable of regio- and enantioselective oxygenations and halogenations of organic substrates. When performed chemically, these reactions typically require aggressive reagents and reaction c ...

In this STTR program, Structured Materials Industries, Inc. (SMI) and partners will develop high efficiency, switchable RF filters. The technical approach is based on thin films of paraelectric BaxSr1-xTiO3 and SrTiO3, which can show piezoelectric behavior under an applied DC bias. When integrated into resonator structures, these materials can act as both an RF filter and an RF switch. Combinin ...

The ability to direct the wound pathways following injury could provide a critical path in wound care at crucial times during the progression of healing. A promising field of study in wound healing is epigenetics; alterations in gene expression caused by mechanisms other than changes in DNA sequence. Identification of epigenetic factors and their manipulation may result in the development of nov ...

ABSTRACT: The CTI/SU team proposes the Cyber Cross-Layer Optimization Publish-Subscribe (CYCLOPS) framework for design, prototyping and assessment of innovative methods for creating cognitive network architectures and protocols to achieve autonomous network resiliency in contested Radio Frequency spectra. Within this framework, the team will design metrics for estimating the benefits, costs and r ...

ABSTRACT: This work proposes the design of a complete, compact, hybrid atom chip system for producing ultracold atoms, allowing subsequent control and manipulation of ultracold atoms using both optical and magnetic fields. Its emphasis is on optical lattice potentials and also complex potentials imposed by spatially varying magnetic and optical fields. Atom chips that incorporate optical windows ...

ABSTRACT: This proposal details an ambitious effort to develop Virtualization-based secure application Containers and Controlled Communication System (VC3S). The VC3S provides secure application/module isolation, mediation of inter-application/module communication, as well as dynamic/intelligent exposure to the Internet. The proposed approach is three-pronged and enables the application of the pr ...

ABSTRACT: We propose to develop modeling and initial concept feasibility demonstration for MWIR lasers that span the 2.4-4 um wavelength span. The laser active region design is based on a novel quantum well design that is grown on InP substrates. The laser will leverage our team's recent advances and demonstrations in quantum well design be use Princeton Lightwave's laser fabrication pl ...

ABSTRACT: Mycotoxins are lipophilic agents derived from fungus that pose a significant public health problem around the world. The effects of mycotoxins include loss of human and animal life, increased healthcare and veterinary costs, reduced livestock production, and disposal of contaminated foods and feeds. Mycotoxins, such as aflatoxin and T-2 mycotoxins, have been reported to be weaponized as ...
