Mass-loss from Red Giants
(2007)Although much is known about the nature of winds from hot stars and giants and supergiants with spectral types earlier than K, there is still much to be learned regarding the mass-loss process in cool, late-type stars. ... -
Materials and devices for organic electronics
(2011)Organic electronics have attracted much attention in recent years due to their multiple advantages such as high flexibility, easy processing, low fabrication cost, and large area fabrication. These unique advantages make ... -
Measurement of Degree of Order in Mixed Polarised Fluorescent Polymer Liquid Crystal Films
(1998)Raman spectroscopy is used to investigate the degree of order found in in situ photopolymerised films exhibiting polarised emission. Studies indicate that the mixed system shows differing degrees of order for its two ... -
Measurement of electric-field intensities using scanning near-field microwave microscopy
(2003)In this paper, we propose methods for the measurement of electric intensities of a microwave field above the surface of microwave circuits. Using miniaturized coaxial antennas, we measure all spatial components of the ... -
Measurement of electron temperature and state of ionization in laser-produced plasmas by use of dielectronic satellite lines
(American Physical Society, 1989) -
Measurement of fast-electron energy spectra and preheating in laser-irradiated targets
(American Physical Society, 1979)Fast electrons produced by the irradiation of plane-layered targets with 20-J, 100-ps, 1015-W.cm-2, neodymium-laser pulses have been diagnosed by the K? emission which they cause at various depths in the targets. The ... -
Measurement of Foam Density Profiles Using AC Capacitance
(EDP Sciences, 1995)The dynamics of foam drainage (free, forced and pulsed) is monitored by the determination of local liquid density using a vertical array of capacitors. Liquid profiles are obtained for various drainage experiments. The ... -
Measurement of nanotube content in pyrolytically generated carbon soot
(2000)Carbon nanotubes can be efficiently separated from impurity material in carbon soot using a conjugated polymer filtration system as monitored by EPR, allowing the calculation of purity of the crude carbon soot. -
Measuring Dynamic Structural Changes of Nanoparticles at the Atomic Scale Using Scanning Transmission Electron Microscopy
(2020)We propose a new method to measure atomic scale dynamics of nanoparticles from experimental high-resolution annular dark field scanning transmission electron microscopy images. By using the so-called hidden Markov model, ... -
Measuring the lateral size of liquid-exfoliated nanosheets with dynamic light scattering
(2013)We have developed an in-situ method to estimate the lateral size of exfoliated nanosheets dispersed in a liquid. Using standard liquid exfoliation and size-selection techniques, we prepared a range of dispersions of graphene, ... -
Mechanical aspects of nanoimprint patterning
(IEEE, 2003)Nanoimprinting is a high resolution, parallel nanopatterning technique where, typically, a rigid stamp is brought into contact with a thin polymer film and pattern transfer achieved by the application of force and heat. ... -
Mechanical properties of individual electrospun polymer-nanotube composite nanofibers
(2009)Singlewalled carbon nanotube/polyvinylalcohol composite nanofibers were electro-spun onto a silicon surface pre-patterned with trenches. These nanofibers were prepared with different loadings of SWCNTs and had radii between ... -
The mechanics of liquid foams: history and new developments
(2011)The story of some recent developments in foam rheology is related at key points to the remarkable early contributions of Henry Princen, who pioneered the rigorous modern development of the subject. His general approach of ... -
Mechanism for the failure of the Edwards hypothesis in the Sherrington-Kirkpatrick spin glass
(2006)The dynamics of the Sherrington-Kirkpatrick model at T=0 starting from random spin configurations is considered. The metastable states reached by such dynamics are atypical of such states as a whole, in that the probability ... -
Mechanisms of Imprint Effect on Ferroelectric Thin Films
(2005)We have developed a single/double layer model to explain horizontal shifting of measured D-E hysteresis loops (imprint) for ferroelectric thin films. Such phenomenon can be explained by considering three mechanisms or their ... -
Mechanisms of Liquid Phase Exfoliation for the Production of Graphene
(2020)Liquid- phase exfoliation (LPE) is the principal method of producing two-dimensional (2D) materials such as graphene in large quantities with a good balance between quality and cost and is now widely adopted by both the ... -
Mechanochromic and Thermochromic Sensors Based on Graphene Infused Polymer Opals
(2020)High quality opal-like photonic crystals containing graphene are fabricated using evaporation-driven self-assembly of soft polymer colloids. A miniscule amount of pristine graphene within a colloidal crystal lattice ... -
Metal Nanoparticle Film Deposition by Femtosecond Laser Ablation at Atmospheric Pressure
(2020)Nanoparticle gold films were deposited using femtosecond laser ablation in argon at atmospheric pressure in an arrangement where a flat Au target was irradiated through a transparent substrate in close proximity. Spatially ... -
Metal surface enhanced emission from CdTe quantum dots
(IEEE, 2005)In this paper the enhancement in emission from CdTe quantum dots (QDs) on Au island film as a function of CdTe-Au distance is reported. The observed enhancement can be partially explained by increased absorption cross ...
