In the Lilliputian world of nanofabrication, where billions of microscopic circuit elements are sculpted or imprinted on a fingernail-sized silicon chip
We use acoustic techniques in gases to measure the thermodynamic temperature of a gas in a spherical or cylindrical cavity, the optical absorption in gases and aerosols (in collaboration with NIST’s Chemical Sciences Division) the quantity of gas in a large vessel or tank, and gas flow into/from a
We apply our expertise in micro/nanofabrication, electrokinetics and cell-based assays to develop bioelectronic sensors in microfluidic platforms. We are working on a platform that entraps cells for electrochemical monitoring in an environment that has mechanical properties more similar to those
The dynamic properties of bulk fluids remain a challenge to predict. Predicting the dynamic properties of confined fluids represents a greater scientific and engineering challenge. Developing simple heuristics or even robust correlations will be helpful in developing and understanding technologies
With appropriately validated assays, digital polymerase chain reaction (dPCR) determines the number of DNA targets (copies) per reaction partition, without the need for a standard curve. Reaction partitions can be in the form of fixed chambers in a microfluidic device, referred to as chamber digital

Rod-like particles are efficient rheology modifiers and are commonly found in a variety of biological and industrially relevant suspensions, from biofilaments
We develop a rheological model to approximate the nonlinear rheology of wormlike micelles using two constitutive models to represent a structural transition at
Applications often expose wormlike micelle solutions to a very wide range of shear and temperature conditions. The two-species model presented in Part I

Polyolefins, including high density polyethylene (HDPE) and isotactic polypropylene (iPP), account for over half of the worldwide plastics market and have wide
