Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 76006-33-2, Name is 3-Bromo-2-methylbenzoic acid, molecular formula is , belongs to bromides-buliding-blocks compound.

Self-supported nickel cobalt carbonate hydroxide nanowires encapsulated cathodically expanded graphite paper for supercapacitor electrodes
The self-standing electrode materials with large surface area and high electronic conductivity have attracted intensive attention in energy storage devices. Herein, the expanded graphite paper (EGP) is fabricated via a controlled cathodic expansion in acetonitrile with tetrabutylammonium bromide at 10 V. The as-prepared EGP exhibits a three-dimensional porous structure with large specific surface area and high electronic conductivity, which is a favorable support for in situ growing nickel cobalt carbonate hydroxide (NiCo-CH) nanowires via a simple hydrothermal method. The as-prepared NiCo-CH@EGP composite achieves high areal capacity of 2.55 C cm(-2) at 0.5 mA cm(-2), and still remains 1.38 C cm(-2) even at 60 mA cm(-2) . The assembled NiCo-CH@EGP//activated carbon asymmetric supercapacitor exhibits the maximum energy density of 0.30 mWh cm(-2) at a power density of 0.92 mW cm(-2) , and a suitable cyclic stability with the capacity retention of 78.1 % after 10,000 cycles at 20 mA cm(-2). The results indicate that the self-standing NiCo-CH@EGP is a potential electrode material for energy storage devices. (C) 2020 Elsevier Ltd. All rights reserved.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 76006-33-2, in my other articles.
