The influence of an active positive charge group ( N(CH3)2) on the phase structure of the aforementioned IPNs was studied. The results show not only that the size of phase segregation zones varies with composition but also that the specific interfacial surface areas have a maximum when the ...
This study focused on how the local structures in pure [N(CH3)4]2ZnBr4 crystal are affected by the partial replacement of Zn2+ ions with Cu2+ ions. The structures and phase transition temperatures TC of perovskite-type [N(CH3)4]2Zn1-xCuxBr4 (x = 0,
8. Additionally, novel groups of perovskite materials, such as [(CH3)2NH2]Zn(HCOO)3, composed of an organic cation and a metal ion, have been discussed36,37,38,39,40,41,42. These materials show potential for application in memory manipulation devices and next-generation memory storage tech...
Further experimental results reveal that the Pb[N(CN)2]2 additives slowdown the formation process of the MAPbI3 crystallite thin film, of which the grain size reaches up to 900 nm with 0.2 M concentration of Pb[N(CN)2]2 additives in the MAPbI3 precursor solutions (1 M), accordant ...

This effect was most significant in the case of fibers with the addition of S iO2 particles. The spectrum of distribution of fibers collected on the collector during the ES process was the widest. The aging process also evidently led to a change in the direction of the fiber. Impact ...
Equation (26) ignores the effect of convection on droplet evaporation and shows that the steady-state evaporation rate depends only on the fuel material properties. However, heat and mass transfer, hence, the evaporation rate depend on Nu and Sh via Gr in the transient model, as shown by Eqs...
These mRNA changes are opposite of that induced by TCR signalling, which enhances branching25. Mgat1 has a ~250-fold higher affinity for UDP-GlcNAc than Mgat5 and over expression of Mgat1, particularly in the presence of reduced Mgat4 and Mgat5, decreases branching by limiting UDP- GlcNAc ...
The elemental analysis of the obtained PNVBA and different poly(NVBA-co-NVF) copoly- mers were in good agreement with the calculated values (Table 2). A representative 1H-NMR spectrum of poly(NVBA-co-NVF) (for that 973 m CH2 CH NH CO CH2 CH2 CH3 NVBA n CH2 CH + NH CO H NVF ...
