2D Excitons as Primary Energy Carriers in Organic Crystals: The Case of Oligoacenes
(American Physical Society, 2010-05)A number of organic crystals show anisotropic excitonic couplings, with weak interlayer interactions between molecules that are more strongly coupled within the layers. The resulting energy carriers are intralayer 2D ... -
2D full-waveform modeling of seismic waves in layered karstic media
(Society of Exploration Geophysicists, 2016-03)We have developed a new propagator-matrix scheme to simulate seismic-wave propagation and scattering in a multilayered medium containing karstic voids. The propagator matrices can be found using the boundary element method. ... -
2D material based field effect transistors and nanoelectromechanical systems for sensing applications
(Elsevier BV, 2021)Sensors are ubiquitous in modern society because of their wide applications in healthcare, security, forensic industries as well as environmental protection. Specifically, sensors which can be microfabricated employing ... -
2D protrusion but not motility predicts growth factor–induced cancer cell migration in 3D collagen
(Rockefeller University Press, The, 2012-06)Growth factor–induced migration is a critical step in the dissemination and metastasis of solid tumors. Although differences in properties characterizing cell migration on two-dimensional (2D) substrata versus within ... -
2D-defocusing nonlinear Schrödinger equation with random data on irrational tori
(Springer US, 2020-05-07)Abstract We revisit the work of Bourgain on the invariance of the Gibbs measure for the cubic, defocusing nonlinear Schrödinger equation in 2D on a square torus, and we prove the equivalent result on any tori. -

2D-Visualisierung des zellulären Sauerstoff verbrauchs in Mikrofluidiksystemen
(Springer Berlin Heidelberg, 2014-11)A new imaging system allows visualizing oxygen distributions in 2D. Combining sensor foils with microfluidic devices enables online monitoring of cellular oxygen consumption in whole chip areas. Furthermore, suitable device ... -
2DEG electrodes for piezoelectric transduction of AlGaN/GaN MEMS resonators
(Institute of Electrical and Electronics Engineers (IEEE), 2013-07)A 2D electron gas (2DEG) interdigitated transducer (IDT) in Gallium Nitride (GaN) resonators is introduced and demonstrated. This metal-free transduction does not suffer from the loss mechanisms associated with more commonly ... -
A 2km-size asteroid challenging the rubble-pile spin barrier – A case for cohesion
(Elsevier BV, 2015-12)The rubble pile spin barrier is an upper limit on the rotation rate of asteroids larger than ~200-300. m. Among thousands of asteroids with diameters larger than ~300. m, only a handful of asteroids are known to rotate ... -
2MASS J06164006-6407194: THE FIRST OUTER HALO L SUBDWARF
(American Astronomical Society, 2009-04)We present the serendipitous discovery of an L subdwarf in the Two Micron All Sky Survey (2MASS) J06164006–6407194, in a search of the 2MASS for T dwarfs. Its spectrum exhibits features indicative of both a cool and metal ... -
2MASS J20261584–2943124: AN UNRESOLVED L0.5 + T6 SPECTRAL BINARY
