Non-specular Reflective Optics

Kavli Affiliate: Richard Foster | First 5 Authors: Timir Datta, Ming Yin, Yunjin Wang, Michael Wescott, Richard Foster | Summary: Geometrically decorated two-dimensional (2D) discrete surfaces can be more effective than conventional smooth reflectors in managing wave radiation. Constructive non-specular wave scattering permits the scattering angle to be other than twice that of incidence and […]

Magnetic Domains and Surface Effects in Hollow Maghemite Nanoparticles

Kavli Affiliate: Paul Alivisatos | First 5 Authors: Andreu Cabot, A. Paul Alivisatos, Victor F. Puntes, Lluis Balcells, Oscar Iglesias | Summary: In the present work, we investigate the magnetic properties of ferrimagnetic and noninteracting maghemite (g-Fe2O3) hollow nanoparticles obtained by the Kirkendall effect. From the experimental characterization of their magnetic behavior, we find that […]

Origin of undesirable cracks during layer transfer

Kavli Affiliate: Harry Atwater | First 5 Authors: Laurent Ponson, Kenneth Diest, Harry Atwater, Guruswami Ravichandran, Kaushik Bhattacharya | Summary: We investigate the origin of undesirable transverse cracks often observed in thin films obtained by the layer transfer technique. During this process, two crystals bonded to each other containing a weak plan produced by ion […]

3D vortex formation of rigid and flexible plates in impulsively starting motion

Kavli Affiliate: Morteza Gharib | First 5 Authors: Daegyoum Kim, Morteza Gharib, , , | Summary: This fluid dynamics video shows three-dimensional vortex formation process for plates in impulsive motion which is investigated experimentally by using defocusing digital particle image velocimetry (DDPIV). Rigid and flexible plate cases are compared in order to study the effect […]

Stability of additive-free water-in-oil emulsions

Kavli Affiliate: Jos Zwanikken | First 5 Authors: Jos Zwanikken, Joost de Graaf, Markus Bier, RenĂ© van Roij, | Summary: We calculate ion distributions near a planar oil-water interface within non-linear Poisson-Boltzmann theory, taking into account the Born self-energy of the ions in the two media. For unequal self-energies of cations and anions, a spontaneous […]

New CTI Correction Method for the Spaced-Row Charge Injection of the Suzaku X-Ray Imaging Spectrometer

Kavli Affiliate: Gregory Prigozhin | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: The charge transfer inefficiency (CTI) of the X-ray CCDs on board the Suzaku satellite (X-ray Imaging Spectrometers; XIS) has increased since the launch due to radiation damage, and the energy resolution has been degraded. To improve the CTI, we have […]

Telescope Optics and Weak Lensing: PSF Patterns due to Low Order Aberrations

Kavli Affiliate: Paul Schechter | First 5 Authors: Mike Jarvis, Paul Schechter, Bhuvnesh Jain, , | Summary: In weak lensing investigations, galaxy shapes are deconvolved for the effects of the point spread function (PSF) using stellar images. In this paper we use physical models of the telescope optics to understand the spatial variation of the […]
