X-type

W-type inks use water, or mixtures of water and alcohol, as the solvent. Inks which are not of a recognized type are classified as X-type. The solvent required is specific to the ink formula and the ink maker makes proper recommendations. 

The 2eohte sodium X (type 13X) has a crystallographic aperture of 0.74 nm. This compares well with the adsorbate value of 0.81 nm. ZeoHte calcium X exhibits a smaller apparent pore si2e of 0.78 nm (lOX). This difference is probably due to some distortion of the aluminosihcate framework upon dehydration and calcium ion migration. 

Films may be formed only ia dowastroke (X-type, Fig. 4b). The depositioa speed may affect the depositioa mode (16,17). If depositioa occurs only when films are formed ia upstroke Z-type films result (Fig. 4c). These are cases where the head group is aot as hydrophilic, eg, COOCH (18), or where the alkyl chain is termiaated by a weak polar group, eg, NO2 (19). la both cases the iateractioas betweea adjaceat moaolayers are...

In tbe first attempt to prepare a two-dimensional crystalline polymer (45), Co y-radiation was used to initiate polymerization in monolayers of vinyl stearate (7). Polymerization at the air—water interface was possible but gave a rigid film. The monomeric monolayer was deposited to give X-type layers that could be polymerized in situ This polymerization reaction, quenched by oxygen, proceeds via a free-radical mechanism. 

Figure 3-8 is a plot of Ca, Cb, Cq, and Cd for a hypothetical system of the Scheme X type. An interesting feature is the time delay after the start of the reaction before the final product, D, appears in significant concentrations. This delay in product appearance is called an induction period or lagtime. In order to observe an induction period it is only necessary that the system include several relatively stable intermediates, so that the bulk of the material balance is temporarily stored in these prior forms. An experimental measurement of the induction period requires an arbitrary definition of its length. 

The zeolites with applications to FCC are Type X, Type Y, and ZSM-5. Both X and Y zeolites have essentially the same crystalline structure. The X zeolite has a lower silica-alumina ratio than the Y zeolite. The X zeolite also has a lower thermal and hydrothermal...

Improvement of Mm(Ni - Co - A1 - Mn)x type alloys has been achieved in various ways. It was reported that alloys with a nonstoichiometric composition [Mm(Ni - Co - Mn - Al), 4.5 < jc < 4.8] had a larger discharge capacity than those with stoichiometric alloys [26-27J. Using X-ray diffraction analysis, it was found that the larger capacity is dependent on an increase in the unit cell volume of alloys with x=4.5-4.8. It was also reported that annealing treatment improved the durability of this type of alloy. 

Here Nx is the active center deactivated by X and P is the polymer molecule. 02, C02, C2H2 appear to be X-type inhibitors. 

Multiayer L-B films can be prepared in both methods, by repeated deposition of monolayer on the substrate, with the molecular direction changing alternatively after each deposition (Y-type), or keeping the same molecule direction in all monolayers (X-type or Z-type).

It should suffice to point out that the shifts In the g value, the number of spin centers, the line widths, and analysis of the EPR Lorentzlan-Spectra confirmed In general the Interpretations deduced from the magnetic X type characterization.
