Atomistic wear in a single asperity sliding contact.

Physical review letters

Gotsmann B, Lantz MA.
PMID: 18851384
Phys Rev Lett. 2008 Sep 19;101(12):125501. doi: 10.1103/PhysRevLett.101.125501. Epub 2008 Sep 16.

Abrasive wear of sharp silicon tips sliding distances of up to 750 m on a polymeric surface is studied using atomic force microscopy. The data cannot be explained by conventional macroscopic wear models. We present a new model in...

Probe based surface modification of polymers below 30 nm pitch.

Journal of nanoscience and nanotechnology

Knoll A, Wiesmann D, Pires D, Gotsmann B, Dürig U.
PMID: 21128454
J Nanosci Nanotechnol. 2010 Jul;10(7):4538-42. doi: 10.1166/jnn.2010.2367.

Heated probes are used to modify the surface of polymeric thin films by thermomechanical indentation and local evaporation of material. The resolution of the processes is discussed for probe-storage and surface patterning-applications. As storage densities exceed 1 Tbit/in2, the...

Assessing the psychometric properties and the perceived usefulness of the BasisRaadsOnderzoek (BARO) as a first-line screening instrument for juvenile offenders.

Child and adolescent psychiatry and mental health

Doreleijers TA, Boonmann C, van Loosbroek E, Vermeiren RR.
PMID: 21714910
Child Adolesc Psychiatry Ment Health. 2011 Jun 29;5:24. doi: 10.1186/1753-2000-5-24.

BACKGROUND: The aim of this study is to investigate the psychometric properties and the perceived usefulness of the BARO (Dutch: BAsisRaadsOnderzoek; Protection Board Preliminary Examination of Juvenile Suspects). The BARO is a first-line screening instrument for the identification of...

Trace2PS and FSA2PS: two software toolkits for converting trace and fsa files to PostScript format.

Source code for biology and medicine

Krawczyk J, Goesmann A, Nolte R, Werber M, Weisshaar B.
PMID: 19622158
Source Code Biol Med. 2009 Jul 21;4:4. doi: 10.1186/1751-0473-4-4.

BACKGROUND: Due to the advanced techniques in sequencing and fragment analysis, DNA sequencers and analyzers produce vast amounts of data within short time. To administrate the large data volume conveniently, efficient data management systems are used in order to...

Nanoscale frictional dissipation into shear-stressed polymer relaxations.

Physical review letters

Jansen L, Schirmeisen A, Hedrick JL, Lantz MA, Knoll A, Cannara R, Gotsmann B.
PMID: 19658951
Phys Rev Lett. 2009 Jun 12;102(23):236101. doi: 10.1103/PhysRevLett.102.236101. Epub 2009 Jun 09.

Sliding friction between a silicon tip and a highly cross-linked polyaryletherketone film is studied using friction force microscopy. The friction force as a function of temperature between 150 and 500 K shows distinctive maxima corresponding to alpha and beta...

Nanoscale three-dimensional patterning of molecular resists by scanning probes.

Science (New York, N.Y.)

Pires D, Hedrick JL, De Silva A, Frommer J, Gotsmann B, Wolf H, Despont M, Duerig U, Knoll AW.
PMID: 20413457
Science. 2010 May 07;328(5979):732-5. doi: 10.1126/science.1187851. Epub 2010 Apr 22.

For patterning organic resists, optical and electron beam lithography are the most established methods; however, at resolutions below 30 nanometers, inherent problems result from unwanted exposure of the resist in nearby areas. We present a scanning probe lithography method...

Relaxation kinetics of nanoscale indents in a polymer glass.

Physical review letters

Knoll A, Wiesmann D, Gotsmann B, Duerig U.
PMID: 19392238
Phys Rev Lett. 2009 Mar 20;102(11):117801. doi: 10.1103/PhysRevLett.102.117801. Epub 2009 Mar 17.

Nanometer scale indents have been written in a cross-linked polystyrene sample, and their relaxation has been studied at annealing temperatures well below the glass transition of the polymer. The indents represent a highly nonequilibrium state of the polymer which...
