Well-studied examples of nanoscale systems include semiconductor nanocrystals, carbon nanotubes (CNTs), organic conjugated polymers, and molecular aggregates, shown in Figure 23.1. e excitons in quantum dots and CNTs are closely related to molecular excited states; however, the size of the nanoscale systems has force…
According to the International Union for Pure and Applied Chemistry (IUPAC) (Work et al., 2004), a composite material is dened as “a multicomponent material comprising multiple different (non-gaseous) phase domains in which at least one type of phase domain is in a continuous phase.” IUPAC also extends its denition…
Carbon nanotubes (CNs) are thin hollow cylinders made entirely out of carbon atoms (see Figure 2.1). ere are many types of CNs and CN-like structures. e most basic ones are multiwall nanotubes (with diameters, dt, of order ∼10 nm) and single-wall nanotubes (SWNT) (dt ∼1 nm). Multiwall carbon nanotubes were discovered…
Printing holds a particular attraction as a potential manufacturing method because it is scalable, has good throughput, and short design-to-production turnaround time. It is also an additive processing method in which the material is placed exactly where it is required. is provides a fundamentally more eÀcient use of…
We would like to start by stating that this is not meant to be a complete account of all di erent aspects of the fullerene fragmentation eld of study. e subject is far too wide for that, and instead we focus on few aspects that, in our view, are central to the problem of fullerene fragmentation including discussions o…
Nanostructured materials can be regarded as articially synthesized materials that have constituent grain structures or morphological features modulated on a length scale less than 100nm. e principal impetus toward fabricating nanostructured materials lies in the promise of achieving unique properties and superior pe…
SWCNTs are the one-dimensional allotropes of carbon, completing the list of zero-(the fullerenes (Kroto et al. 1985) ), two-(the graphene (Novoselov et al. 2004) ), and three-dimensional (graphite and diamond) carbon allotropes. An interesting property of SWCNTs is that all constituent carbons are equivalent and close…
Of course, the chapter does not cover all aspects of sp2 single layers. Topics like free-standing layers (Geim and Novoselov, 2007), edge structures of ribbons (Enoki et al., 2007; CervantesSodi et al., 2008), topological defects (Coraux et al., 2008), or mechanical and chemical properties are not covered.
The title complex, [Ni(C(12)H(8)N(2))(2)(H(2)O)(2)][Ni(CN)(4)]·C(4)H(8)O·H(2)O, consists of a cationic [Ni(C(12)H(8)N(2))(2)(H(2)O)(2)](2+) unit, an anionic [Ni(CN)(4)](2-) unit, one uncoordinated water and one tetra-hydro-furan mol-ecule. In the cationic unit, the Ni(2+) atom is coordinated by four N atoms and two O…
Recent advances in the RF atomic iodine generator for oxygen-iodine lasers are presented. The generator is based on the RF discharge dissociation of a suitable iodine donor immediately before its injection to the flow of singlet oxygen. The discharge is ignited directly in the iodine injector, and the configuration is…
We present theoretical and experimental results of nanohole fabrication on a silicon substrate by plasmonic near field around multiple gold nanoparticles excited by oblique incidence of femtosecond laser. Using the enhanced near field around a gold nanoparticle, nanohole can be fabricated on the substrate surface even…
An extensive analytical and numerical study on a class of growth processes with spatiotemporally correlated noise in arbitrary dimension is undertaken. In addition to the conventional investigation on the interface morphology and interfacial widths, we pay special attention to exploring the characteristics of the slop…
The possibility of developing compact all solid-state lasers for short-wavelengths based on laser diode pumped single fluoride crystals is considered. The paper reviews our work and important data from the literature.
Mikroporöse Gerüste aus starren organischen Baueinheiten können in Lösung durch Sol-Gel-Verfahren prozessiert werden. In ihrer Zuschrift auf S. 9694 ff. beschreiben J.-W. Park und Mitarbeiter, wie molekulare organische Gerüste unter Bildung von Nanopartikeln wachsen, die in stabilen Organosolen dispergiert sind. Durch…
The most recent fundamental research results to investigate surface erosions of nuclear fusion candidate chamber materials are described in short. We used a commercial surface profiler with a red semiconductor laser. Various material surfaces ablated and eroded by a rather short pulse electron beam and a short pulse A…
Offen für Zusammenschluss: Hydrophob modifizierte Molecular Beacons wurden in Lipidnanopartikel eingeführt. Bei Zugabe der Ziel-DNA zu einer Lösung der Lipidnanopartikel erfolgte eine irreversible Nanopartikelaggregation (siehe Bild), die aus der Öffnung der Molecular Beacons resultiert.
Although the choice of monometallic nanoclusters is the most common, bimetallic particles have also been investigated because they are used for several industrial catalyzed reactions. e physical and chemical properties of bimetallic particles are found to be di erent from their single metal counterparts, and they are…
Based on a series of ab initio simulations, Boustani proposed an “Au au Principle,” stating that the most stable boron clusters can be constructed using two basic units: pentagonal and hexagonal pyramids, B6 and B7, respectively [11].
Nanotechnologies and nanomaterials are arguably the most actively and extensively developing research areas at the beginning of this century. e number of publications in scienti c periodicals and conference proceedings, fully or partially devoted to nanotechnologies and nanomaterials, is rapidly increasing. However, t…
Biology has evolved elegant pathways, molecular structures, and complex machinery at the nanoscale to power sophisticated cell functioning. However, control of molecular processes requires extensive knowledge about the physical and chemical properties of molecules and assemblies that constitute cell machinery. Control…
