Surface electromigration patterns in a confined adsorbed metal film: Ga on GaN.

Chemphyschem : a European journal of chemical physics and physical chemistry

Barinov A, Gregoratti L, Kaulich B, Kiskinova M.
PMID: 12516212
Chemphyschem. 2002 Dec 16;3(12):1019-23. doi: 10.1002/cphc.200290003.

The mass transport of gallium adatoms in a confined gallium bilayer on GaN(0001) is studied with photoelectron spectromicroscopy with the goal to identify the diffusing species and their lateral distribution during directional surface electromigration and/or "random" thermal diffusion. It...

Beam-shaping condenser lenses for full-field transmission X-ray microscopy.

Journal of synchrotron radiation

Jefimovs K, Vila-Comamala J, Stampanoni M, Kaulich B, David C.
PMID: 18097086
J Synchrotron Radiat. 2008 Jan;15:106-8. doi: 10.1107/S0909049507047711. Epub 2007 Dec 18.

A new type of diffractive X-ray optical elements is reported, which have been used as beam-shaping condenser lenses in full-field transmission X-ray microscopes. These devices produce a square-shaped flat-top illumination on the sample matched to the field of view....

Delayed Mesoderm and Erythroid Differentiation of Murine Embryonic Stem Cells in the Absence of the Transcriptional Regulator FUBP1.

Stem cells international

Wesely J, Steiner M, Schnütgen F, Kaulich M, Rieger MA, Zörnig M.
PMID: 28588622
Stem Cells Int. 2017;2017:5762301. doi: 10.1155/2017/5762301. Epub 2017 May 15.

The transcriptional regulator far upstream binding protein 1 (FUBP1) is essential for fetal and adult hematopoietic stem cell (HSC) self-renewal, and the constitutive absence of FUBP1 activity during early development leads to embryonic lethality in homozygous mutant mice. To...

A Sub-Microanalysis Approach in Chemical Characterisation of Gold Nanorods Formed by a Novel Polymer-Immobilised Gold Seeds Base.

Nanomaterials (Basel, Switzerland)

Abyaneh MK, Araki T, Kaulich B.
PMID: 29035310
Nanomaterials (Basel). 2017 Oct 16;7(10). doi: 10.3390/nano7100331.

Gold nanorods (GNRs) have been fabricated by a novel polymer-immobilised seed mediated method using ultraviolet (UV) photoreduced gold-polymethylmethacrylate (Au-PMMA) nanocomposites as a seed platform and characterised at sub-micron scale regime with synchrotron-based techniques; near-edge X-ray absorption fine structure (NEXAFS)...

The conserved family of Transmembrane channel-like (TMC) proteins has attracted significant interest since two members appear to be key components of the mammalian hair cell mechanotransducer involved in hearing.

Computational prediction of CRISPR-impaired non-coding regulatory regions.

Biological chemistry

Baumgarten N, Schmidt F, Wegner M, Hebel M, Kaulich M, Schulz MH.
PMID: 33660495

Genome-wide CRISPR screens are becoming more widespread and allow the simultaneous interrogation of thousands of genomic regions. Although recent progress has been made in the analysis of CRISPR screens, it is still an open problem how to interpret CRISPR...

Differential interference contrast x-ray microscopy with twin zone plates.

Journal of the Optical Society of America. A, Optics, image science, and vision

Kaulich B, Wilhein T, Di FE, Romanato F, Altissimo M, Cabrini S, Fayard B, Susini J.
PMID: 11934173
J Opt Soc Am A Opt Image Sci Vis. 2002 Apr;19(4):797-806. doi: 10.1364/josaa.19.000797.

X-ray imaging in differential interference contrast (DIC) with submicrometer optical resolution was performed by using a twin zone plate (TZP) setup generating focal spots closely spaced within the TZP spatial resolution of 160 nm. Optical path differences introduced by...

Diffractive optical elements for differential interference contrast x-ray microscopy.

Optics express

Di Fabrizio E, Cojoc D, Cabrini S, Kaulich B, Susini J, Facci P, Wilhein T.
PMID: 19471336
Opt Express. 2003 Sep 22;11(19):2278-88. doi: 10.1364/oe.11.002278.

In this paper we introduce phase diffractive optical elements (DOEs) that beside simple focusing, can perform new optical functions in the range of x-rays. In particular, the intensity of the wavefront can be distributed with almost complete freedom. We...

Soft X-ray spectromicroscopy using ptychography with randomly phased illumination.

Nature communications

Maiden AM, Morrison GR, Kaulich B, Gianoncelli A, Rodenburg JM.
PMID: 23575673
Nat Commun. 2013;4:1669. doi: 10.1038/ncomms2640.

Ptychography is a form of scanning diffractive imaging that can successfully retrieve the modulus and phase of both the sample transmission function and the illuminating probe. An experimental difficulty commonly encountered in diffractive imaging is the large dynamic range...

Condenser for Koehler-like illumination in transmission x-ray microscopes at undulator sources.

Optics letters

We report on a novel condenser for full-field transmission x-ray microscopes that use synchrotron radiation from an undulator source. The condenser produces a Koehler-like homogeneous intensity distribution in the sample plane and eliminates object illumination problems connected with the...
