Measurement of the inclusive and differential t(t)over-bar gamma cross sections in the dilepton channel and effective field theory interpretation in proton-proton collisions at root s=13 TeV

Matthias Finger, Varun Sharma, Olivier Martin, Ian Smith, Jean-François Carlin, Arvind Shah, Rakesh Chawla, Thomas Mountford, Chao Wang, João Miguel das Neves Duarte

The production cross section of a top quark pair in association with a photon is measured in proton-proton collisions in the decay channel with two oppositely charged leptons (e(+/-)mu(-/+), e(+)e(-), or mu(+)mu(-)). The measurement is performed using 138 ...

Probing fibronectin-antibody interactions using AFM force spectroscopy and lateral force microscopy

Andrzej Kulik, Kyumin Lee

The first experiment showing the effects of specific interaction forces using lateral force microscopy (LFM) was demonstrated for lectin-carbohydrate interactions some years ago. Such measurements are possible under the assumption that specific forces stro ...

Fibrogenic fibroblasts increase intercellular adhesion strength by reinforcing individual OB-cadherin bonds

Andrzej Kulik, Jean-Jacques Meister, Boris Hinz, Kyumin Lee, Philippe Pittet

We have previously shown that the switch from N-cadherin to OB-cadherin expression increases intercellular adhesion between fibroblasts during their transition from a migratory to a fibrogenic phenotype. Using atomic force microscopy we here show that part ...

Surface-bound nanostructures : mechanical and metrological studies

Kyumin Lee

This thesis looks at surface-bound nanowires and nanoparticles, the mechanical and the metrological properties of which are of practical importance in the realization of nanometer-scale electronics. Atomic force microscope (AFM) was the main instrument of ...

Preparation, stabilization and characterization of TiO2 on thin polyethylene films (LDPE): Photocatalytic applications

Albert Renken, Philippe Buffat, Lioubov Kiwi, Juan Kiwi, Andrzej Kulik, Danièle Laub, Kyumin Lee

An innovative way to fix preformed nanocrystalline TiO2 on low-density polyethylene film (LDPE-TiO2) is presented. The LDPE-TiO2 film was able to mediate the complete photodiscoloration of Orange II using about seven times less catalyst than a TiO2 suspens ...

Uniformly Dispersed Deposition of Colloidal Nanoparticles and Nanowires by Boiling

Jürgen Brugger, László Forró, Arnaud Magrez, Andrzej Kulik, Sylvia Jeney, Jin Won Seo, Kyumin Lee, Martial Duchamp, Gerit Kulik, Ravi Shankar Sundaram

Uniformly dispersed deposition of various nanoparticles (gold and silver of 20?50 nm) and nanowires (ZnO and VOx) on different surfaces (Si, GaAs, mica, and steel) was obtained by boiling colloid drops on preheated substrates. Our results suggest a deposit ...

Diameter-Dependent Elastic Modulus Supports the Metastable-Catalyst Growth of Carbon Nanotubes

László Forró, Arnaud Magrez, Andrzej Kulik, Jin Won Seo, Branimir Lukic, Kyumin Lee

We measured the elastic modulus of individual multiwalled carbon nanotubes (MWCNTs) grown by catalytic chemical vapor deposition (CVD) over a broad diameter range (10-25 nm). Alternating current (ac) dielectrophoresis was used for efficient tube deposition ...

Catalytically grown carbon nanotubes: from synthesis to toxicity

László Forró, Arnaud Magrez, Jin Won Seo, Kyumin Lee, Mirko Milas

Catalytic chemical vapour deposition (CCVD) is currently the most promising technique to produce carbon nanotubes (CNTs) on a specific site as well as on a large-scale. Here, we review our recent experimental studies on CNTs grown by CCVD. The yield as wel ...
