Nanoelectromechanical devices integrate mechanical elements, such as resonators, actuators, and sensors, with electronic circuits. ese elements consist of structures that come in numerous shapes and forms, ranging from single doubly clamped beams, disks, rings, gears, and squares to more elaborate geometries. Nanomec…
Various pharmaceutical nanocarriers, such as nanospheres, nanocapsules, liposomes, micelles, polymeric nanoparticles, dendrimers, nanotubes, cell ghosts, lipoproteins, and some others, are widely used for experimental (and even clinical) delivery of therapeutic and diagnostic agents (Gregoriadis 1988, Müller 1991, Rol…
Extreme ultraviolet (EUV) lithography extends conventional optical lithography to higher resolution because it utilizes an exceedingly short imaging wavelength (λ = 13.5 nm) and provides a larger depth of focus because it employs a small numerical aperture (NA = 0.25) imaging system. Although it has a number of simila…
Silicon, the second-most abundant element on earth (a§er oxygen) having superior mechanical and electronic properties, has become the principal material of the semiconductors industry from the dawn of microelectronics, and apparently will remain dominant in the foreseen future. Silicon is a semiconductor whose electri…
Di erent from scanning probe and electron microscopy-related techniques, optics is one of the oldest characterization techniques for materials science, being largely used long before nanoscience could even be imagined. In the age of nano, optics still sustains its kingdom. e advantages of optics for nanoscience relate…
Ferroic nanomaterials open the way to obtain a variety of new unique magneto-mechanical, electro-mechanical, electronic, and dielectric properties, a lot of which are useful for applications. For example, their ability to store and release energy in well-regulated manners makes them very useful for sensors and actuato…
The structure of the title compound, vanadium indium penta-deca-molybdenum nona-deca-selenide, V(1.42)In(1.83)Mo(15)Se(19), is isotypic with In(2.9)Mo(15)Se(19) [Grüttner et al. (1979 ▶). Acta Cryst. B35, 285-292]. It is characterized by two cluster units Mo(6)Se(i) (8)Se(a) (6) and Mo(9)Se(i) (11)Se(a) (6) (where i r…
Metal atoms adsorbed on few-layer graphenes condense to form nanometer-size droplets whose growth is size limited by a competition between the surface tension and repulsive electrostatic interactions from charge transfer between the metal droplet and the graphene. For situations where the work-function mismatch is lar…
Abstract Results of time‐dependent simulations of growth of bulk binary III–V crystals by current controlled liquid phase electroepitaxy (LPEE) are presented using GaAs as example. Without any electrical current the LPEE system is isothermal, kept at 1073 K, thus no growth occurs. The electric current density of 10 A/…
Whether a given material shows magnetism is delicately controlled by its structural and geometrical properties, such as the interatomic distances, coordination number (i.e., the number of nearest neighbors), and symmetry. e main consequences of the structural modi cations in nanostructured materials are the following…
Over the past decade, e orts have been made toward understanding and predicting the fate of nanomaterials in biological systems (Ke and Qiao, 2007) and, quite recently, in the environment (Colvin, 2003; Nel et al., 2006; Maynard et al., 2006). e motivations for making such e orts are twofold. First, it is desirable to…
Metal oxides have numerous technological applications and provide an excellent platform to study various fundamental physical processes and phenomena existing in the material systems. Metal oxides crystallize in a multitude of crystal structures and exhibit diverse properties. For example, several metal oxides have th…
Carbon nanotubes (CNTs) have attracted great enthusiasm among researchers due to their extraordinary mechanical, electrical, and thermal properties. e use of polymers lled with CNTs is especially interesting as an extension of research on composites. e number of publications on CNTs and CNT/ polymer composites has…
Graphene is a truly two-dimensional (2-D) crystal consisting of a honeycomb-like hexagonal lattice of carbon atoms, as illustrated in Figure 21.1a. e carbon atoms form strong covalent bonds by three in-plane sp2 hybridized orbitals, whereas the fourth valence electron of the 2s22p2 orbitals of carbon, assigned to the…
Abstract Co‐rich Co–Pt alloy films have been grown by electrodeposition on Au buffer layer. Detailed texture measurements have been performed in order to understand the dependence of magnetic properties on phase composition and texture. X‐ray analysis in Bragg–Brentano geometry shows that films seem to consist of hexa…
According to the classication made by International Union of Pure and Applied Chemistry (IUPAC) [1], porous materials can be divided into three main categories depending on their pore size, that is, the microporous materials with pore size under 2 nm, the mesoporous materials with pore size between 2 and 50 nm, and t…
Abstract New considerations of the stability problem of dewetting, as addressed in the initial paper [Cryst. Res. Technol. 39, 491 (2004)], show that, in the most general case, when dewetting occurs in microgravity it is necessarily stable. This explains why the phenomenon has been observed so many times during solidi…
A design method of electromagnetic (EM) cloaks which can change the scattering pattern of the concealed object to that of a reduced perfect electric conducting (PEC) line or ring (two-dimensional case) is proposed in this paper. It is based on the radial transformation method. The boundary of the concealed space is cr…
The energy scale ${\ensuremath{\Omega}}_{0}$ of the electron-boson spectral function in the heavy-fermion, $d$-wave superconductor ${\text{NpPd}}_{5}{\text{Al}}_{2}$ is predicted on the basis of Eliashberg theory calculations. Assuming a spectral function shape typical for antiferromagnetic spin fluctuations, and impo…
Several representative, interfacially active silver(I) nitrate alkylsulfide complexes were synthesized and characterized in detail. The complexes form extended structures in the solid state and in solution. Interestingly, a two-phase approach, in which aqueous silver nitrate is combined with organically dissolved sulf…
