INTRODUCTION: Point of care diagnostics aimed at low-resource settings need to be relatively simple, robust and low-cost. The most commonly-used diagnostic platform in these settings is the lateral flow assay (LFA). LFAs are paper-based immunoassays designed to perform on-strip binding ... Read More

The pore sizes of many membranes being studied for separating the components in gas mixtures are on the scale of nanometers. Depending on the specific gases and pressures being used, this scale will put the flows in the Transition between Slip Flow and Knudsen regime. The differential ... Read More

Introduction The constitutive behavior of Polyethylene, like most polymers, is nonlinear, temperature, and strain-rate dependent. It cannot be accurately represented with standard elastic-plastic or hyperelastic material models [1]. The focus of this work is on Medium Density ... Read More

An analysis to quantify the flow inside the narrow channels of an ISS (International Space Station) CDRA (Carbon Dioxide Removal Assembly) adsorbent bed is presented. The CDRA contains two pelletized adsorbent beds to remove CO2 respired by the crew. Heaters and associated fins inside ... Read More

Electroporation is a biotechnological technique which subjects cells to strong (~kV/cm), short (~ms) electric field pulses that open pores on the cells’ plasma membranes. Under the appropriate conditions, the pores mediate the passage of exogenous material into cells. If the pores ... Read More

Electrospray propulsion is a contemporary type of thruster technology that electrostatically drives particles through an extractor grid without the need of a pump. The basis of this propulsion system is the coalescence of propellant into a Taylor cone and through a charged extraction ... Read More

Introduction: Single-photon detectors capable of ensuring high fidelity read-out of quantum information delivered via photons of specific polarization are crucial in QIP [1]. Our previous studies have shown that different types of one dimensional plasmonic structures enhance the ... Read More

Uncertainty appears in many aspects of physical simulations including stochastic design parameters, hard-to-specify input distributions, probabilistic boundary and initial conditions, and unknown geometries. Uncertainty Quantification (UQ) has emerged as the science of quantitative ... Read More

Combustion instability modeling of Solid Rocket Motors (SRM) remains a topic of active research. Many rockets display violent fluctuations in pressure, velocity, and temperature originating from the complex interactions between the combustion process, acoustics, and steady-state gas ... Read More

The primary interest of the VC (Vacuum Characterization) test is to experimentally characterize the adsorption and vacuum desorption of CO2 and water vapor of a pelletized sorbent bed in a large diameter column. The VC test article is shown in Figures 1 and 2. The aluminum canister is 3” ... Read More
