DOI: 10.1140/epjst/e2007-00197-4 THE EUROPEAN PHYSICAL JOURNAL SPECIAL TOPICS Universal non-equilibrium phenomena at submicrometric surfaces and interfaces
"... Abstract. The recent widespread interest in processes occurring at micro and nanometric scales has increased the physical relevance of the surfaces and inter-faces constituting system boundaries, both at and far from equilibrium. In the latter case, universal properties occur, such as scale invarian ..."

invariance (surface kinetic roughening), surface pattern formation or domain coarsening. However, descrip-tions of these systems feature limited predictive power when based merely on universality principles. We review examples from Materials Science at nano and submicrometric scales, that underlie
Specific Effects and Deconvolution in Submicrometre EPMA: Application to Binary Diffusion
"... Electron probe (X-ray) microanalysis (EPMA) is nowadays a classical and well-established method for qualitative and (semi)quantitative evaluation of the elemental composition of the (near)surface of a sample on the micrometre scale. This technique can be used to determine concentration profiles due ..."

AC Electrokinetics: A Review of Forces in Microelectrode Structures
- Journal of Physics D: Applied Physics
, 1998
"... Abstract. Ac electrokinetics is concerned with the study of the movement and behaviour of particles in suspension when they are subjected to ac electrical fields. The development of new microfabricated electrode structures has meant that particles down to the size of macromolecules have been manipul ..."

manipulated, but on this scale forces other than electrokinetic affect particles behaviour. The high electrical fields, which are required to produce sufficient force to move a particle, result in heat dissipation in the medium. This in turn produces thermal gradients, which may give rise to fluid motion
Free-standing graphene at atomic resolution
- Nat. Nanotechnol
"... Research interest in graphene, a two-dimensional crystal consisting of a single atomic plane of carbon atoms, has been driven by its extraordinary properties, including charge carriers that mimic ultra-relativistic elementary particles. Moreover, graphene exhibits ballistic electron transport on the ..."

on the submicrometre scale, even at room temperature, which has allowed the demonstration of graphene-based field-effect transistors and the observation of a room-temperature quantum Hall effect. Here we confirm the presence of free-standing, single-layer graphene with directly interpretable atomic-resolution imaging
Membrane nanodomains in T-cell antigen receptor signalling
, 2015
"... Abstract The organization of the T-cell's plasma membrane continues to nourish the curiosity of immunologists, cell biologists and biophysicists. The main reason is the biological and biomedical interest to understand the workings of the cell-cell communication network activated by T-cells dur ..."

. Many T-cell membrane proteins act as receptors to carry out and finely tune these complex tasks. However, the TCR (T-cell receptor) holds a decisive hegemony for its crucial contribution in steering T-cell function and fate. An emerging notion is that TCR proximal signalling occurs at submicrometre-scale

Modelling and simulation of freeform surface generation in ultra-precision raster milling
, 2006
"... Abstract: Optical freeform surfaces are large-scale surface topologies with shapes generally possessing non-rotational symmetry with submicrometric form accuracy and nanometric surface finish. Due to the geometrical complexities, the prediction of form accuracy in ultra-precision raster milling of u ..."
