dodecyltrimethylammonium bromide(the main carbon chain of the ammonium has 12 carbon atoms, C12) and cetyltrimethylammonium bromide. They are labeled as MCM-41 (C12) and MCM-41 (C 16), respectively. The other two are commercial porous silicas (Kieselgel 60 and silica gel 40 Ǻ from ...
It may be that the surface of sheet ADN is rough and angular, so the force between the coating material and ADN is weak, which makes the coating effect not obvious. Table 2. Moisture absorption rates of ADN with different shapes and different coating materials. SamplesCoating amount/%Moisture...
however, the limited pressure-sensitivity and large hysteresis of phase transition hinder the colossal barocaloric effect accomplished reversibly at low pressure. Here we report reversible colossal barocaloric effect at low pressure in two-dimensional van-der-Waals alkylammonium halides. Via introducing long...
Although the adjuvant, DDA, promotes a strong cross-reactivity in DH between heterologous hapten-carrier complexes, the antibody-forming cells produced 4 days after challenge showed relatively high specificity for the immunizing hapten. This indicates only weak cross-reactivity at the antibody-forming ...
Yue Wang1, Wei Wu2, Tao Jing1, Surong Mei1 &Yikai Zhou1 In this work, we fabricated an electrochemical sensor based on trimethyloctadecylammonium bromide and multi-walled carbon nanotubes-Fe3O4 hybrid (TOAB/MWCNTs-Fe3O4) for sensitive detection of tetrabromobisphenol A (TBBPA)....
The molecules of TBAB/BNP and TPAB/BNP are held in their aggregates by strong hydrogen bond (O-H…Br) and weak hydrogen bonds; C-H…O, C-H…Br, and C-H…π. The packing structures are different from each other, as well as those observed in tetrabutylammonium bromide with planar ...
it was too large to support the transfer of the surface alignment to the LC molecules, due to the weak anchoring nature of HTAB. We also showed the phase-change characteristic of the LC mixture related to [HTAB] for the design of RF devices driven by light or heat. This study may ...
In this reaction, ordinary reagents used to produce quaternary ammonium compounds can be used, examples of which include linear or branched alkyl halides having 1 to 12 carbon atoms such as methyl iodide, ethyl iodide, butyl bromide, isobutyl bromide, hexyl bromide, octyl bromide, decyl bromide ...
And for red fluorescence of Cyto C, except for weak signal diffused in the cytoplasm, most of the strong spot signal was retained in the mitochondria.DMAE-CB impacts the morphologies and functions of mitochondria We further examined mitochondria morphology in cells exposed to DMAE-CB, in the ...
The weak to medium intense peaks at 1393 and 1319 cm−1 indicates the existence of –CH-NH2+ group that causes stretching frequency vibrations of C-N bond [54–56]. The strong signal at 919 and 780 cm−1 is attributed to Cr-O bond asymmetric and symmetric stretching vibrations, ...
