Investigating an Inkjet Printer for Standardized Sample Preparation

Holthoff E.L., Farrell M.E., Marcus L.S., Pellegrino P.M., US Army Research Laboratory, US

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

Farrell M.E., Holthoff E.L., Marcus L.S., Pellegrino P.M., US Army Research Lab, US

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

Vader S., Vader Z., Vader S., Vader Z., Karampelas I.H., Furlani E.P., SUNY-Buffalo, US

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

Karampelas I.H., Alali F., Furlani E.P., SUNY-Buffalo, US

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 [...]

An Integrated Biometric Platform for Evaluation of Targeted Drug Delivery

Liu Y., Thomas A., Uhl C., Wang S., He R., Lehigh University, US

In order to develop in vitro methods, which more closely resemble in vivo environments, a novel technology involving the use of microfluidic devices, which more closely mimic blood vessels has been developed. The technology has [...]

Bottom-up Nanofabrication of Crystalline Structures of Magnetic Nanoparticles

Xue X., Furlani E.P., SUNY at Buffalo, US

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 [...]

Microfluidics for multiplexing of core needle biopsies

Mojica W.D., Oh K.W., Lee H., Xue X., Furlani E.P., University at Buffalo, US

Image guided biopsies for the procurement of diagnostic tissue has proven to be safe, cost effective and useful. However, the amount of tissue obtained is often diminutive and may be exhausted for conventional diagnostic purposes. [...]

A Simple Method for Fabrication of Microarrays and Microfluidic Device Using PDMS Stamp

Lee H., Koh D., Oh K.W., SUNY at Buffalo, US

We describe a simple micro-fabrication method by using polydimethylsiloxane (PDMS) stamp on a glass substrate. While the microwells used previously facilitated the cell-to-cell formation by PDMS stamping method, not only should it be carefully controlled [...]

Wireless, One-way, Sensor to Base Station Monitoring System for Explosive and Non-hazardous Environments

Jensen S.L., NASA - Stennis Space Center, US

The technology developed is a monitoring system that includes a base station and at least one sensor unit mounted at some distance away, which is in wireless, one-way communication with the base station. The sensor [...]
