It is established that a Cr 2 Co 3 O 6 · 10H 2 O hydrocomplex precipitates in the Cr(III)-Co(II) -NO 3 - H 2 O system at pH = 3.0 –10.5 and is dehydrated at 940°C. The compound obtained can be used as a pigment for preparing overglaze paints and color glazes for ...
Spinel oxides: NiCo2O4[61,62], ZnCo2O4[63,64], ZnIr2O4[63] and ZnRh2O4[65,66], etc.; (vii) Others: SnSeO [67], Ba2BiTaO6[68], SrCu2O2[69,70,71], [Cu2S2][Sr3Sc2O5] [72] or La2/3Sr1/3VO3[73]. From a general point of view, these materials have failed to full...

In general, chemical and physical modification of adsorbents by surfactants aims to enhance the ability of these adsorbents to remove pollutants and achieve higher efficiency50. Cetyl trimethyl ammonium bromide (CTAB) is a cationic detergent, soluble in H2O, less toxic, highly biodegradable surfactant ...
3. Electrochemical dissolution of the oxide (Reactions 2, 3, 4, and 5) dominates over chemical dissolution (e.g., NiO + 2H+⇌Ni2+ + H2O, Cr2O3 + 6H+⇌2Cr3+ + 3H2O)43. This assumption holds for all pH ranges for which dissolution requires an applied voltage...
2 μl of the solution was taken for tagmentation with 1 μl Tn5 stock solution and 1.6 μl reaction buffer (50 mM TAPS, 25 mM MgCl2, 40% PEG 8k; final concentration 8% PEG, 5 mM MgCl2, 10 mM TAPS) and 3.4 ml H2O (final vol- ume 8 μl), incubated ...
样品制备过程如下:按照表 1 的配 比将 NH3.H2O 加入一定量的无水乙醇中配成 0.6 mol/L 的沉淀剂 溶液备用 。将片状铝粉加入 400 mL 乙醇溶液 中,超 声震荡使铝粉颜料均匀分散,依次加入 Cr(ON3)3.9H2O 和 SDBS,待原料完全溶解后,在恒 温水浴(6O℃) 、磁力搅拌环境下慢速(2.5 mL/min)滴 入沉淀剂。
