Optofluidic Temperature and Pressure Measurements with Fiber Bragg Gratings Embedded in Microfluidic Devices

Cooksey G.A., Wright J.D., Ahmed Z., National Institute of Standards and Technology, US

(INTRODUCTION) The integration of photonic sensors into microfluidic devices provides opportunities for dynamic measurement of chemical and physical properties of fluids in very small volumes. Microfluidic platforms provide sub-microliter control of fluid transport and mixing [...]

MedeA: An environment for ICME starting with atoms, and what we can learn from it

Saxe P., Materials Design, Inc., US

ICME is a grand vision, but there is an enormous amount of work needed to bring together experiment and simulation across the entire spectrum of length- and time-scales to go from atoms to cars, airplanes, [...]

Resonance transmission of the electron wave through the nanofilms containing a magnetic quantum well

Sahakyan A.S., Movsesyan R.M., Kocharian A.N., California State University Los Angeles, US

The transmission of an electron wave through so called a magnetic resonance diode is considered in semiconductor nanofilms consisting of two nonmagnetic barriers separated by a quantum (magnetic) well subjected to an external magnetic field. [...]

Nonholonomic Ab Initio Molecular Dynamics for Computational Materials Design

Fahrenthold E., University of Texas at Austin, US

Nanocomposites research attempts to design new materials with unique or optimized properties, by forming composites at the nanoscale. Previous work has demonstrated the ability to significantly modify the mechanical, electrical, magnetic, thermal, or chemical properties [...]

Multiscale Modeling of Organic-Inorganic Semiconductor Materials: Opportunities and Challenges

Stevenson J., Saathoff J., Clancy P., Cornell University, US

Many of the most interesting new materials that show promise for solar photovoltaics, involve atomic species, like lead and selenium, that are non-traditional from the point of view of computational modeling. This poses a problem [...]

Nanofabrication with Lanthanum Hexaboride (LaB6) for Nanoscale Vacuum Electronics

Mankin M.N., Pan T.S., Modern Electron, US

We present the first nano- and microfabrication of vacuum microelectronic components incorporating lanthanum hexaboride (LaB6), a refractory low work function material with high electron emissivity. We design novel fabrication processes which yield ultra-low fill factor [...]

Advances in Magnetohydrodynamic Molten Metal Jet Printing

Vader S., Vader Z., Vader S., Vader Z., Karampelas I.H., Furlani E.P., University at Buffalo (SUNY), US

At present, most metal 3D printing applications involve deposited metal powder sintering or melting under the influence of an external energy source such as a laser (e.g. Selective Laser Sintering (SLS) [1] and Direct Metal [...]

Continuous Preparation of Polymer Nanocomposites for Applications in Novel Substrates, Multilayered Materials, and 3D Printing

Barry C., Kazmer D., Mead J., University of Massachusetts-Lowell, US

Polymer nanocomposites are composed of a nanofiller, such as nanoclay, carbon nanotubes, graphene, and nanosilver, in a polymer matrix. Depending on the choice of filler, these nanocomposites exhibit unique material properties, including improved barrier properties, [...]

Effect of β-Silicon Carbide Size and Shape on the Properties and Microstructure of PMMA Matrix Nanocomposites

Watt M.R., Gerhardt Ro.A., Georgia Institute of Technology, US

The objective of this research is to fabricate, beginning with screen printing, electrically conductive glass nanocomposite films and optimize their properties. By discovering an optimum thickness and nanoparticle spacing within the glass matrix, we may [...]

Reviving natural product and drug discovery pipelines with fungal artificial chromosome (FAC) technology

Clevenger K., Bok J.W., Ye R., Miley G., Velk T., Chen C., Yang K.H., Gao P., Lamprecht M., Thomas P., Islam M.D., Keller N., Kelleher N., Wu C., Intact Genomics, Inc., US

We have developed the fungal artificial chromosome [FAC, or autonomously replicating E. coli- fungal shuttle bacterial artificial chromosome (BAC)] vector and system. The FAC technology enables unbiased capturing of 263 full-length large secondary metabolite (SM) [...]
