Spin resolved bandstructure imaging with a high resolution momentum microscope.

Ultramicroscopy

Tusche C, Krasyuk A, Kirschner J.
PMID: 25840475
Ultramicroscopy. 2015 Dec;159:520-9. doi: 10.1016/j.ultramic.2015.03.020. Epub 2015 Mar 24.

We present a spin resolving "momentum microscope" for the high resolution imaging of the momentum distribution of photoelectrons. Measurements of the band structure of a Au(111) single crystal surface demonstrate an energy resolution of ΔE=12 meV and a momentum...

Distractor-Induced Blindness: A Special Case of Contingent Attentional Capture?.

Advances in cognitive psychology

Winther GN, Niedeggen M.
PMID: 28439320
Adv Cogn Psychol. 2017 Mar 31;13(1):52-63. doi: 10.5709/acp-0206-5. eCollection 2017.

The detection of a salient visual target embedded in a rapid serial visual presentation (RSVP) can be severely affected if target-like distractors are presented previously. This phenomenon, known as distractor-induced blindness (DIB), shares the prerequisites of

A low energy ion source for electron capture spectroscopy.

The Review of scientific instruments

Tusche C, Kirschner J.
PMID: 24985812
Rev Sci Instrum. 2014 Jun;85(6):063305. doi: 10.1063/1.4884900.

We report on the design of an ion source for the production of single and double charged Helium ions with kinetic energies in the range from 300 eV down to 5 eV. The construction is based on a commercial...

Effects of enriched postoperative housing conditions on spatial memory deficits in rats with selective lesions of either the hippocampus, subiculum or entorhinal cortex.

Restorative neurology and neuroscience

Galani R, Coutureau E, Kelche C.
PMID: 12671278
Restor Neurol Neurosci. 1998;13(3):173-84.

Long-Evans male, adult rats received selective and bilateral lesions of either the hippocampus, subiculum or lateral entorhinal cortex, and were then housed for 30 days in either enriched or standard conditions. Rats were then tested in the eight-arm radial...

Airborne high spectral resolution lidar for measuring aerosol extinction and backscatter coefficients.

Applied optics

Esselborn M, Wirth M, Fix A, Tesche M, Ehret G.
PMID: 18204721
Appl Opt. 2008 Jan 20;47(3):346-58. doi: 10.1364/ao.47.000346.

An airborne high spectral resolution lidar (HSRL) based on an iodine absorption filter and a high-power frequency-doubled Nd:YAG laser has been developed to measure backscatter and extinction coefficients of aerosols and clouds. The instrument was operated aboard the Falcon...

Direct evidence for conduction pathways in a solid electrolyte.

Physical review letters

Escher C, Latychevskaia T, Fink HW, Pohl DW.
PMID: 17026057
Phys Rev Lett. 2006 Sep 29;97(13):136601. doi: 10.1103/PhysRevLett.97.136601. Epub 2006 Sep 26.

The emission of silver ions from the apex of an amorphous electrolyte tip has been investigated by field ion microscopy. The ion emission patterns show discrete nanometer-sized spots. We present evidence that they represent the termination of bulk ion...

Polymerization of w/o microemulsions for the preparation of transparent SiO2/PMMA nanocomposites.

Langmuir : the ACS journal of surfaces and colloids

Palkovits R, Althues H, Rumplecker A, Tesche B, Dreier A, Holle U, Fink G, Cheng CH, Shantz DF, Kaskel S.
PMID: 15952859
Langmuir. 2005 Jun 21;21(13):6048-53. doi: 10.1021/la050630k.

Reverse w/o microemulsions composed of methyl methacrylate (MMA) forming the oil phase, nonionic surfactants, and water are used for the synthesis of transparent SiO2/PMMA nanocomposites. An inorganic precursor, tetraethoxysilane (Si(OEt)(4), TEOS), is hydrolyzed in the reverse micelles containing aqueous...

Microkinetic videomicroscopic analysis of olefin polymerization with a supported metallocene catalyst.

Preventive intervention for school-age deaf children: the PATHS curriculum.

Journal of deaf studies and deaf education

Greenberg P, Kusche C.
PMID: 15579857
J Deaf Stud Deaf Educ. 1998;3(1):49-63. doi: 10.1093/oxfordjournals.deafed.a014340.

This study examined the effectiveness of the PATHS (Promoting Alternative THinking Strategies) Curriculum on the social, cognitive, and behavioral status of elementary school-age deaf children. PATHS, a school-based preventive intervention model, was designed to improve children's self-control, emotional understanding,...
