Tailoring behavior

A 5 year randomized clinical trial in the United States found that in spite of the availability of hypertensive medication, awareness promotions, and guidelines, only a third of all the hypertensive patients have their blood pressure under effective control due to noncompUance in medication. More tailored behavioral management intervention may help to improve compliance and achieve better control. 

Tailoring block copolymers with three or more distinct type of blocks creates more exciting possibilities of exquisite self-assembly. The possible combination of block sequence, composition, and block molecular weight provides an enormous space for the creation of new morphologies. In multiblock copolymer with selective solvents, the dramatic expansion of parameter space poses both experimental and theoretical challenges. However, there has been very limited systematic research on the phase behavior of triblock copolymers and triblock copolymer-containing selective solvents. In the future an important aspect in the fabrication of nanomaterials by bottom-up approach would be to understand, control, and manipulate the self-assembly of phase-segregated system and to know how the selective solvent present affects the phase behavior and structure offered by amphiphilic block copolymers. 

It is well known that LCB has a pronounced effect on the flow behavior of polymers under shear and extensional flow. Increasing LCB will increase elasticity and the shear rate sensitivity of the melt viscosity ( ). Environmental stress cracking and low-temperature brittleness can be strongly influenced by the LCB. Thus, the ability to measure long chain branching and its molecular weight distribution is critical in order to tailor product performance. 

Precisely, this behavior is found for the host 26 (see Sect. 4.1), another properly tailored carboxylic add (cf. Sect. 4.5). The crystal structure of the 1-butanol associate of 26 (Fig. 18 b) shows the same 12-membered H-bond pattern around a center of symmetry as found for the inclusions of I with MeOH, EtOH, and 2-PrOH and exactly the same building principle (dimeric host and 12-ring formation) as in the 1-PrOH aggregate of 1. Thus, they both belong to the same type lib of building blocks (Fig. 19). 

Some of the results obtained by differential centrifugation showed enzyme distribution between different cell fractions which were difficult to interpret. Enzymes like carbamoyl phosphate synthase or isocitrate dehydrogenase were found both in mitochondria and in the soluble fraction of the cell. This led to detailed kinetic studies with purified enzymes which indicated there might be populations of enzymes with slightly different properties (isozymes) catalyzing similar reactions in different compartments or in different cell types. Variations in kinetic behavior appeared to tailor the enzyme appropriately to the particular compartment or cell where the reaction took place. 

Besides the practical application, the diversity of nanostructured carbon allotropes makes nanocarbon also an ideal model system for the investigation of structure-function correlations in heterogeneous catalysis. Nanocarbons can be tailored in terms of their hybridization state, curvature, and aspect ratio, i.e., dimensions of stacks of basic structural units (BSU), Chapters 1 and 2. The preferred exposition of two types of surfaces, which strongly differ in their physico-chemical behavior, i.e., the basal plane and prismatic edges, can be controlled. Such controlled diversity is seldom found for other materials giving carbon a unique role in this field of basic research. The focus of this chapter is set on the most prominent representatives of the... 

Carbon nanotubes inevitably contain defects, whose extent depends on the fabrication method but also on the CNT post-treatments. As already seen, oxidizing treatments, such as acid, plasma or electrochemical, can introduce defects that play an important role in the electrochemical performance of CNT electrodes. For instance, Collins and coworkers have published an interesting way to introduce very controlled functionalization points or defects on individual SWNTs by electrochemical means [96]. Other methodologies to introduce artificial defects comprise argon, hydrogen and electron irradiation. Under this context, a number of recent works have appeared with the goal of tailoring the electrochemical behavior of CNT surfaces by the controlled introduction of defects [97, 98].
