Rotation-induced splitting of the otherwise degenerate photonic bands is predicted for a two-dimensional photonic crystal made of evanescently coupled microcavities. The symmetry-broken energy splitting is similar to the Zeeman splitting of atomic levels o ...
We present an in-detail description of the design, simulation, fabrication, and packaging of a linear micromirror array specifically designed for temporal pulse shaping of ultrashort laser pulses. The innovative features of this device include a novel comb ...
A complete characterization, based on fs pump-probe spectroscopy and mol. dynamics simulations, is presented of the ultrafast dynamics of electronic bubble formation in solid para-H2 upon impulsive excitation of impurity-doped sites, which correlate with t ...
We present a detailed analysis of the band structure of the root 3 x root 3 R 30 degrees BiAg2/Ag/Si(111) trilayer system by means of high resolution Angle Resolved Photoemission Spectroscopy (ARPES). BiAg2/Ag/Si(111) exhibits a complex spin-polarized elec ...
We investigated the localized rotational diffusion of the (BH 4)- anions in LiBH4/LiI solid solutions by means of quasielastic and inelastic neutron scattering. The (BH 4)- motions are thermally activated and characterized by activation energies in the ord ...
This paper presents low-profile torsional actuators applicable for mesoscale and microscale robots. The primary actuator material is thermally activated Ni-Ti shape memory alloy (SMA), which exhibits remarkably high torque density. Despite the advantages o ...
We are developing a linear array of micromirrors designed for optical, femtosecond laser pulse shaping. It is a bulkmicromachined device, capable of retarding or diminishing certain laser frequencies in order to perform phase and amplitude modulation withi ...
The Golgi complex (GC) represents the central junction for membrane trafficking. Protein and lipid cargoes continuously move through the GC in both anterograde and retrograde directions, departing to and arriving from diverse destinations within the cell. ...
We present an original concept of manipulation of magnetic microbeads in a microchannel. It is based on the dynamic motion of a self-assembled structure of ferrimagnetic beads that are retained within a microfluidic flow using a local alternating magnetic ...
A new global analysis of EPR, 17O NMR relaxation and chemical shift and 1H NMRD profiles with physically meaningful parameters for [Gd(DOTA)(H2O)]− and for [Gd(DTPA)(H2O)]2− in aqueous solution is presented (DOTA=1,4,7,10-tetraaza-1,4,7,10-tetrakis(carboxy ...
