an aqueous medium and is such that the surface treating agent has at least a functional group capable of forming an ionic bond; and the functional group and a charge control agent form an ionic bond; and the developer contains the above toner; the image forming method is carried out by ...
The exposure, development and curing steps were carried out in the same manner as in Example 1, except that no ester bond type photosensitive polyimide precursor layer was formed and only an ionic bond photosensitive polyimide precursor composition was applied in a thickness of 10 μm. Consequently...
It is demonstrated that even the molecules possessing high ionization potentials (such as SiO(2), NH(3), CHCl(3), CCl(2)F(2)) should form stable and strongly bound ionic compounds when combined with a properly chosen superhalogen system (acting as an oxidizing agent). The conclusion is ...
An improved siloxane-based composition for use as a low &kgr; dielectric material in integrated circuit applications is provided, the composition exhibiting desirable thermal mechanical stability compared to conventional siloxane-based l... EA Chandross,VJ Kuck - US 被引量: 46发表: 2001年 Study ...
Obviously, in the case of reactions with methane there is no CC bond to break, so an alternative mechanism must necessarily operate. One difference in the bond-forming reactivity exhibited by the three systems relates to the facility for the stripping of H− from the organic molecule by O22...
Global warming and urbanization are likely to increase fires in natural and urbanized areas, requiring advanced fire management techniques such as the use of aqueous film forming foams. However, these foams contains in particular toxic fluorinated compounds that belongs to the class of the so-called...
atomically flat SrTiO3 (Nb 0.5 wt %; SrTiO3:Nb) or quartz glass chips, Figure 8 Sensors based on LbL films of inorganic nanostructures: (a) an LbL film of mesoporous carbon CMK-3; (b) an LbL film of mesoporous carbon capsule and (c) an LbL film of graphene nanosheet and ionic ...
They form the apatite when they take an anatase-like structure even though they do not contain CaO. These results indicate that a specific structure of the titanium oxide is more important for the apatite nucleation than the magnitude of the ionic activity products of the apatite in the ...
Suzuki cross-coupling reactions of aryl halides in phosphonium salt ionic liquid under mild conditions The Suzuki1cross-coupling reaction has become a standard method for carbon–carbon bond formation between an sp2or non-β-hydride containing elect... J Mcnulty - 《Chemical Communications》 被引量...
Sectional porous carriers may be constructed from inorganic materials as various alkali element or related conjugated salts present in a carrier solvent (e.g. water, etc.). Such conjugated salts may exist in an ionic mixture where cations may include ammonium (NH4−), hydronium (H3O+) and me...
