Investigation of heterozygousity of yeast plasmid
… found in the yeast species, specifically the 2-micron plasmid found in the yeast species. It explains the materials and methods used during this research, including the GATK software used to sequence the plasmid genome. An extensive table of results was made, listing the strain name, if the …

Towards personal fabrications : tabletop tools for micron and sub-micron scale functional rapid prototyping
Three tools for the rapid prototyping of micron and sub-micron scale devices are presented. These tools represent methods for the manufacture of PEMS, or Printed micro Electro Mechanical Systems, and are enabled because they exploit the novel properties of nanocrystalline materials and their …

Development of a Humidity-Resistant Coating to Impart High Oxygen Barrier Performance to Food Packaging Films
… resins. In this work, we demonstrate a 1 – 2 micron thick oxygen barrier coating, prepared on a 12 micron poly(ethylene terephthalate) substrate, that has oxygen transmission rates as low as 1.44 cc m<sup>-2</sup> day<sup>-1</sup> under standard conditions and can maintain similar oxygen …

Limits of long wavelength High Harmonic Generation
… driver pulse duration for 400 nm, 800 nm and 2 micron driver pulses for a given harmonic for hydrogen.

High speed photodiode and 90° optical hybrid for 2 µm optical communication systems
In order to maximize the capacity using these C-band wavelengths, more and more efforts have to be exerted by the equipment providers to increase capacity and suppress cross talk between adjacent channels. To overcome this capacity saturation around 1.55 µm, the next generation optical networks …

Device integration for silicon microphotonic platforms
… 0.01 dB/turn loss has been measured for 2 micron radius silicon bends. Polarization dependent loss was also observed; the bending loss of a TM mode was, as expected, much larger than that of a TE mode. The splitting losses for two-degree Y-split was 0.15 dB/split. A 1x16 multi-mode …

Broadband Coherent Perfect Absorption in One-Dimensional Optical Systems
… this model through a computational study of a 1-micron-thick silicon layer in a cavity formed of dispersive mirrors with aperiodic multilayer design. We confirm that one may achieve 100% absorption in this thin silicon layer (whose intrinsic absorption is only ~ 3%) in the near-infrared. We then …

Development of the Evanescent Wave Atomic Force Microscope
… used to determine probe-surface separation. Sub-micron sized dielectric and metallic probes show exponential scattering profiles, micron sized polystyrene and borosilicate microspheres show non-exponential profiles when they are affixed beneath the cantilever tip. By affixing the microspheres to …

Tracing meteorite source regions through asteroid spectroscopy
… spectra identically in the calculation of 1-micron and 2-micron geometric band centers and their band area ratios (BARs). Using these identical numerical parameters we quantitatively compare the spectral properties of S-, Sq-, Q- and V-type NEOs with the spectral properties of the meteorites …

Nanoscale BioFETs for ultrasensitive pH and biomolecular detection
… differences in source-drain current for a 2 micron wide nanoplate device compared to a 100 nm wide nanowire device, the pH amplification scheme was shown to theoretically enable the detection of extremely low pH changes, down to 0.002 pH units. The devices were then used for the detection of …

Multiscale Structures and Mechanics of Biomineralized Lattices in Hexactinellid sponges and Echinoderms
… 1) amorphous nanoparticular biogenic silica; 2) micron-sized fibrous spicule with cylindrically laminated silica layers separated by organic interfaces; 3) spicule bundles where the individual spicules merged by secondary silica deposition; 4) a centimeter-sized Voronoi-like cellular dome known …

Interfacial and Physical Confinement Effects on the Structure and Properties of Aligned Carbon Nanotube Architectures
… substrate in Regimes I & II, or break leaving ∼2-micron long CNTs attached to the substrate in Regimes II & III. Morphological and chemical analyses indicate that in all regimes, the Fe catalyst remains on the substrate after CNT array pull-off, and the CNT array structural quality is maintained; …
