Strategy to Solve This Problem

A strategy to solve this problem is to separate the core formation process from the reduction of metal ions in the cores as shown in Scheme 1, and use solvent (EG) and simple ions (OH , etc.) as the stabilizers [11]. In the first step of this process, metal salts hydrolyzed in the alkaline solution of EG to give rise to metal hydroxide or oxide colloids, which were then reduced by EG at elevated temperature to produce colloidal metal nanoclusters in the... [Pg.328]

The general strategies to solve this problem have been discussed extensively in the literature on mathematics [47]. Numerical Recipes [48] and other NMR literature [30, 31, 49] are a good introduction. Even though there are well-established algorithms for performing a numerical Laplace inversion [29-31], its use is not necessarily trivial and requires considerable experience. It is thus useful to understand the essential mathematics involved in the analysis as a better guide to its... [Pg.169]

The concept of de-PEGylation can be applied to the development of nanoparticle-based drug delivery systems. PEG is used for the modification of liposomes to increase their blood circulation time [38], However, it also prevents cellular uptake, resulting in a decrease in therapeutic efficiency thus, modifications of the liposome surface with PEG interfere with membrane fusion to the cell membrane and liposome decomposition [39]. One of the possible strategies to solve this problem is to cleave the PEG chains after the nanoparticle reaches the target site (Fig. 9). This system of de-PEGylation of liposomes is also useful in avoiding the immune... [Pg.123]

Strategy To solve this problem (1) Find the energy cost of a 1,3-diaxial interaction by using Table 4.1. (2) Convert this energy difference into a percent by using Figure 4.12. [Pg.80]

Strategies to solve this problem involve application of adsorptive porous layers on the dense membrane and of metal-oxide composites where the exchange reaction is catalysed by the metal. The study of these surface reactions and of ways to decrease their effect is important. [Pg.18]

One strategy to solve this problem was put forward by Pauling and often forms the basis for tabulated values. Pauling argued that on theo-... [Pg.20]

Strategy The key to solving this problem is to realize that because P, T, and V are the same in the two experiments, the number of moles ofAr and X effusing into the flask is the same ... [Pg.120]

Scheme 2.6 provides an overall view of our strategy towards solving this problem. As depicted, our late generation synthesis embraces three key discoveries that were crucial to its success. We anticipated that the difficult Cl-Cll polypropionate domain could be assembled through a double stereodifferentiating aldol condensation of the C5-C6 Z-metalloenolate system B and chiral aldehyde C. Two potentially serious problems are apparent upon examination of this strategy. First was the condition that the aldol reaction must afford the requisite syn connectivity between the emerging stereocenters at C6-C7 (by uk addition) concomitant with the necessary anti relationship relative to the resident chirality at C8 (by Ik diastereoface addition). Secondly, it would be necessary to steer the required aldol condensation to C6 in preference to the more readily enolizable center at C2. [Pg.18]

Strategy. Let us assume that the Earth s stratosphere is a large homogeneous compartment and that the flows of O2,0, and O3 are given by the four Chapman equations. The concentration of M (N2 and 02) is sufficiently high so that it is virtually a constant. To solve this problem, let us first set up the equations for the steady-state concentrations of O and 03 in other words, we will set up the equations for the rates of formation of O and O3 and set these rates equal to zero. Using these two expressions, we will then calculate the value of the 03 to... [Pg.82]

Strategy To solve this type of problem, read the problem carefully, word for word. Then try to interpret parts of the problem. For example ... [Pg.61]

Another drawback of this kind of sensor is its sensitivity to other active compounds (interferents) that can be present in the medium to be analysed, giving rise to an additional unspecific signal. Several strategies have been developed to solve this problem, but sometimes more than one approach is necessary, especially when the concentration of these interferents is quite high in comparison to those of the metabolites of interest. [Pg.232]
