Because it is a structure with a nonsymmetric center, if an external pressure is applied, the positive and negative charge centers can be disturbed, which will lead to a local dipole moment (Fan and Lu, 2005). Zinc oxide can also exhibit ferromagnetism by adding ferromagnetic or paramagnetic ...
This is due to the high loading of zinc oxide in the 5% sample causing the maximum perturbation of the electromagnetic field of the impedance sensor, due to the increased positive charge associated with the ZnO crystals. Figure 5 Impedance spectra of three different concentrations of ZnO nano-...
However, the charge inter- action between negative peptide and positive metal ions might also play a role in hydrogelation. According to the rheology results (Supplementary Fig. S2), though the value of G' was very low for the solution of Nap- GFFYGGGHGRGD, it was still larger than the ...

Motile Ulva-zoospores on SAMs showed a positive correlation between the attached number of spores and increasing hydrophobicity (Callow et al., 2000). A series of mono-, di-, and trisaccharide-functionalized alkanethiols were synthesized for use in fouling-resistant SAMs (Fyrner et al., 2011)...
(H+) resulting in a high positive surface charge on the surface of the adsorbent which repels the positively charged metal ions and subsequently low removal efficiency. However, due to dominant hydroxide ions (OH−) at a pH greater than 7, the adsorbent surface becomes negatively charged ...
Carbon structures for charge storage with their merits and shortages Full size image 2.1Types of carbon nanostructures as cathode materials 2.1.1One-dimension Carbon nanotube is the representative one-dimensional carbon nanostructure, owning a hollow tubular structure formed by bending one or more layers...
The stability of thin film transistors with zinc oxide as the channel layer is investigated using gate bias stressing techniques. It is found that the application of low positive and negative stress results in the device transfer characteristics shifting in positive and negative directions respectively....

coefficients (r) were positive, or negative with a P value 40.05 were discarded. To ensure maximum stringency, only genes that negatively correlated with all five metallothioneins were kept to form a master list of 867 genes (Supplementary Data 2). Of these 867, a total of 798 genes were ...
