Investigating an Inkjet Printer for Standardized Sample Preparation
Hazard detection systems must be evaluated with appropriate test material concentrations under controlled conditions in order to accurately identify and quantify unknown residues commonly utilized in theater. The existing assortment of hazard reference sample preparation [...]
Depositing Explosives and Chemical Materials on Relevant Surfaces using Inkjet Technology for Calibration Test Standards
Moon R.P., Fountain III A.W., Guicheteau J.A., Christesen S.D., Green N., Hung K., Tripathi A., US Army, US
Materials deposited on manmade or natural surfaces are frequently utilized as calibration standards for chemical or explosive detecting systems. The U.S. Army Edgewood Chemical Biological Center (ECBC) has redesigned a standard inkjet printer to be [...]
Characterization of Inkjet-printed Explosive Materials
The requirement to detect hazardous materials at both point and standoff distances has led to the development of laser-based hazard detection systems with immediate application for the security and safety of the US military, national [...]
Magnetohydrodynamic Liquid Metal Jet Printing
We present a novel method for drop-on-demand (DOD) printing of molten metal droplets into 3D objects. This method involves the use of heating to pre-melt a solid metal structure (e.g. rod) to form a reservoir [...]
Plasmonic Nanocages as Photothermal Transducers for Laser Induced Heating and Bubble Generation
A series of new computational models is introduced to demonstrate several photonic and thermo-fluidic details of the photothermal process associated with nanosecond-pulsed, laser-heated gold nanocages. Such models can be used to simulate energy conversion within [...]
Guidelines for choosing an appropriate turbulence model when simulating blood flows in cardiovascular devices
A systematic and detailed comparative study of computational results with validating experimental data has helped define the turbulence models that are most appropriate for predicting the velocity fields and shear forces in blood flows. The [...]
Low-cost spin-coatable, Transferable, and High-k Ion Gel Dielectric for Flexible Eletrowetting
Electrowetting-on-dielectric (EWOD) is an emerging liquid-handling technology, enabling the wettability modulation of a liquid on a solid surface with an applied electric field. Recently, EWOD has been attractively used on flexible substrates to show potential [...]
Bottom-up Nanofabrication of Crystalline Structures of Magnetic Nanoparticles
A bottom-up approach to the nanofabrication of three-dimensional (3D) crystalline structures of magnetic core-shell nanoparticles is presented. The approach is based on self-assembly and involves the use of soft-magnetic template elements to guide the assembly [...]
