Shell parts

Soot deposited on the chamber wall contained mostly carbonaceous particles, where no MWNTs were contained. The deposits on the cathode consist of two portions the inside is black fragile core and the outside hard shell. The inside include MWNTs scad poljd ral graphitic nanoparticles. The outer-shell part ojnsisted of the crystd of graphite. [Pg.750]

In summary the simultaneous reduction method usually provides alloyed bimetallic nanoparticles or mixtures of two kinds of monometallic nanoparticles. The bimetallic nanoparticles with core/shell structure also form in the simultaneous reduction when the reduction is carried out under mild conditions. In these cases, however, there is difference in redox potentials between the two kinds of metals. Usually the metal with higher redox potential is first reduced to form core part of the bimetallic nanoparticles, and then the metal with lower redox potential is reduced to form shell part on the core, as shown in Figure 2. The coordination ability may play a role in some extent to form a core/shell structure. Therefore, the simultaneous reduction method cannot provide bimetallic nanoparticles with so-called inverted core/ shell structure in which the metal of the core has lower redox potential. [Pg.54]

The best insight into the relaxation behavior of star polymers in dilute solution can be expected if, in addition to the whole star system, different parts of the star are considered separately. This can be achieved easily by neutron scattering techniques on systems where not only the entity of arms, but also single arms, the core or shell parts are labelled by proton deuterium exchange. With respect to the core-shell labelling it is convenient to build up the arms as diblock copolymers of A-B type with protonated or deuterated but otherwise chemically identical A and B blocks. [Pg.90]

For simpUcity, let us return to the true isoenergetic triplet functions given by Eq. (23) involving just the two electrons outside the closed-shell part. [Pg.17]

ONs. All electron spins corresponding to the closed-shell part are then paired (rip = n p= tip) and thus they are coupled as a pure singlet. By the help of the following result (last term in Eq. (84)),... [Pg.414]

Benzene has a closed bonding shell of delocalized tt electrons. This closed bonding shell partly accounts for the stability of benzene. Benzene is more stable than the Kekule structure suggests. The stability of benzene can be shown as follows. [Pg.119]

Shell parts are assembled and positioned in the final mold where casting of the liquid metal takes place. [Pg.284]

The phenolic binder is carbonized in the casting process but the resistance of the shell part is enough to enable the formation of a solid metal skin before the shell part disintegrates. The metallic part is removed from the mold and the remaining sand with the burnt resin is brushed aside. [Pg.284]

In other situations, the neutral oxygen atom may share electrons with one or more other atoms, in order to act as though it has a complete valence shell part of the time. These shared electrons represent covalent bonds and result in the formation of molecular compounds, as shown here ... [Pg.116]

The relativistic many-electron theory can then be formulated in just the same way as in the non-relativistic case above the relativistic x can be obtained and various shells and electron groups separated in it. Because of their strong Z (effective nuclear charge) dependence, relativistic effects will then be confined mainly to the inner shells and will cancel out in the calculations of molecular binding energies and other vedence electron properties. Further approximations may then be made in the formal relativistic theory for the outer shell parts of Xrei and rei to get the non-relativistic equations of this article. [Pg.406]

Notice that the integration over the intermediate momenta k in Eqs. (1) and (2) extends from zero to infinity. For intermediate states with k q, energy is not conserved and the nucleons are off their energy shell ( off-shell ). The off-shell part of the potential (and the T-matrix) is involved. Thus, in the integral term in Eqs. (1) and (2), the potential (and the T-matrix) contributes essentially off-shell. [Pg.26]

Spinning is used to produce axisymmetric shell parts with diameters up to 10 m and with work-pieces up to 25 mm in thickness. Almost aU parts made by spinning could be made by other processes, including deep drawing, but the advantages of spinning are ... [Pg.867]

In the case of PPy as the conductive core material, a PPy-poly(methyl methacrylate) (PMMA) core-shell nanosphere with an average diameter of several tens of nanometers was synthesized via a two-step microemulsion polymerization procedure (Fig. 4) [213]. The size of core and shell parts was easily tuned by adjusting the amount of surfactant and monomer. The shell thickness was maintained in nanometer-scale to minimize the loss of electrical conductivity. [Pg.210]

A PPy-chitosan hollow nanosphere (core diameter 20 3 nm, shell thickness 15 4 nm) has been fabricated by using AgCl nanoparticle as a sacrificial core at 2 °C [221,222]. The core and shell were sequentially formed in the same reaction medium. During the synthetic process, chitosan stabihzed the AgCl nanoparticle and prevented the aggregation of PPy. In addition, the PPy hollow nanosphere was stable in acidic aqueous media and insoluble in basic media due to the presence of chitosan in the shell part. [Pg.212]

Here the indexes c and s are introduced to mark the resonant frequencies and dispersions of core and shell parts respectively. The coefficients A(R) and B(R) are proportional to the volumes of nanoparticles core and shell, the latter has AR size. They are defined by normalization condition / /(go, R)d(i> = 1, that yields... [Pg.146]

With respect to the fact that f(R) has maximum at 7 = Ro, it is easy to see, that for narrow size distribution function the only one line remains in the spectrum. In this case, the conditions AR/Ro < C 1 and AR/Ro 1 correspond to bulk ferroic (core part) or to the surfaee layer (shell part) respectively. In the intermediate case the spectrum consists of two lines if cOc — oo (/ ) > (A + Aj)/2. The above criteria have been confirmed by the detailed numerical calculations of integral (3.98) in Ref. [100]. It has also been shown that the linewidth increases with the size decrease that makes it difficult to meet the criteria of core and shell lines simultaneous observation. The approximate calculations of I((o) by Laplace method [100] for Rq/o > k/(RoAs) lead to the following analytical expression ... [Pg.147]
