Plasmonics: Fundamentals and Applications

The surface science of titanium dioxide

Self-assembly is the autonomous organization of components into patterns or structures without human intervention. Self-assembling processes are common throughout nature and technology. They involve components from the molecular (crystals) to the planetary (weather systems) scale and many different kinds of interactions. The concept of self-assembly is used increasingly in many disciplines, with a different flavor and emphasis in each.

Self-assembly at all scales.

Recent developments have greatly improved the sensitivity of optical sensors based on metal nanoparticle arrays and single nanoparticles. We introduce the localized surface plasmon resonance (LSPR) sensor and describe how its exquisite sensitivity to size, shape and environment can be harnessed to detect molecular binding events and changes in molecular conformation. We then describe recent progress in three areas representing the most significant challenges: pushing sensitivity towards the single-molecule detection limit, combining LSPR with complementary molecular identification techniques such as surface-enhanced Raman spectroscopy, and practical development of sensors and instrumentation for routine use and high-throughput detection. This review highlights several exceptionally promising research directions and discusses how diverse applications of plasmonic nanoparticles can be integrated in the near future.

Biosensing with plasmonic nanosensors

The formation of a (bulk) phase between hydrogen and a metal proceeds through the interaction of H2 molecules with the surface. Conversely, thermal decomposition of a hydride includes recombination of H atoms at the surface as an important step. The schematic one-dimensional potential diagram of Fig. 1 illustrates how a hydrogen molecule approaching a solid passes through the shallow minimum of a molecular \"precursor\" state (H.2,ad) across a possible activation barrier E* into the dissociatively chemisorbed state (rlad), from where eventually penetration into the bulk (through the intermediate formation of\" subsurface\" species) and formation of hydride may take place.

Interaction of Hydrogen with Metal Surfaces

The influence of adsorbed hydrogen on the structure of the surface regions of Ni (110) and Pd (110) was derived from dynamical LEED I/ V -analyses of the clean, (2×1) H covered and (1×2) “row pairing” reconstructed surfaces as reported in earlier publications (see references) In this article the resulting modification of the oscillatory contraction / relaxation of the topmost interlayer spacings of the clean surfaces is discussed in terms of the electrostatic forces acting between these layers The extension of the reconstruction into deeper layers is related to the relief of lattice strain which is shown to be a general phenomenon for reconstructed surfaces

A newly designed analyzer system for measuring the energy distribution of field emitted electrons (FEED) is presented. A Kuyatt–Simpson type lens system is combined with a two‐stage 127° analyzer. A resolution of 15 meV is obtained with a transmission energy of 0.5 eV.

On July 29, 1823, J.W. Doebereiner, professor of chemistry at the University of Jena, informed his minister, J.W. Goethe, about his observation that finely divided platinum causes hydrogen to react with oxygen “by mere contact”, whereby the platinum even starts to glow due to the heat evolved in this process [1.1]. This discovery was a sensation in the scientific world (perhaps comparable to the turmoil about recent reports about the so-called “cold fusion”, with the essential difference that Doebereiner’s effect was real!) and prompted many researchers to further investigations in this field, for which somewhat later Berzelius coined the term “catalysis” [1.2]. A tentative explanation was offered by Faraday [1.3] who speculated: 
“dependent upon the natural conditions of gaseous elasticity combined with the exertion of that attractive force possessed by many bodies …; by which they are drawn into association more or less close, … and which occasionally leads to the combination of bodies simultaneously subjected to this attraction”.
