MID functions

The syntax of the MID function is MID(fexf, start num, num characters) it returns a specific number of characters from a specified position in a text string. For example, if cell A1 contains H2S04, the expression MID(A1,3,1) returns S. 

REPLACE replaces unspecified characters at a specified position within a text string. Note that, except for the inclusion of a fourth argument, new text, its syntax is similar to that of the MID function. 

The code required for the first three steps was described in Chapter 14. We ll (i) use the ActiveCell keyword to obtain the string, (ii) use For... Next to create a loop and the Mid function to access each character within the... 

Prepare a spreadsheet similar to the one shown in Figure 3-7 for the gravimetric determination of nickel using dimethylglyoxime. See Section 37B-3 for details. Use the worksheet from Problem 3-9 to calculate the molar mass of Ni(DMG)2 if it is available. 3-4. Write an Excel formula using the FIND and MID functions to eliminate the square brackets and the uncertainty from the atomic mass of lithium in the lUPAC table and display the numeric characters of the atomic weight. 

Devise an Excel formula using the FIND and MID functions that will automatically display the uncertainties of the atomic masses in the lUPAC table. 3-7. Use the worksheet of Figure 3-15 to calculate the molar masses of the following compounds. 

Jeon et al. [66] investigated the effect of the interfaciai copolymer precursor structure on the reaction rate constant (k). The authors used PMMA chains end-functionalized and mid-functionalized with phthalic anhydride. Both were reacted with PS chains... 

Scheme 11 Synthesis of mid-functional polymers bearing a fluorescent molecule, a terminal double bond, or a RAFT agent by the Ugi-4CR [73]...

For the synthesis of highly defined and complex polymer architectures, the Ugi-4CR serves as conjugation method for two kinds of polymers benzaldehyde-terminated PMMA and aniline-terminated PEG 5000 (Scheme 11) [73], For this purpose, the remaining components, isocyanide and carboxyhc acid, were added in high excess (ten and five equivalents, respectively) to achieve full conversion of the parent polymers. Removal of the excess was accomplished via dialysis. Attractively, this approach not only combines two different polymers, but also facilitates the synthesis of mid-functionalized block copolymers by simple introduction of functional isocyanides or carboxylic acids. In this way, Tao and coworkers introduced a fluorescent molecule via the carboxylic acid (using dansylglycine) or a terminal double bond (using 2-acrylamido acetic acid) to obtain a mid-vinyl PMMA-Z -PEG polymer. Mid-reactive polymers are known to behave differently to their end-functionalized counterparts due to the umbrella-effect [74]. Therefore, it was... 

The contents of each MID feature are stated clearly and unequivocally in a profile. The elements that make up the profile are description, design, MID functions, and process-specific requirements. Essential aspects of the feature are summarized briefly in the description. Small pictograms illustrate the design of the feature. The MID function element refers to the developed MID design catalog, so it points to electronic and mechanical product functions implementable to a qualified extent with the feature. The process-specific requirements deal with issues that have to be taken into account in engineering implementation of the feature. The development of new features is currently a subject of research the feature used here byway of example is alignment. ...
