β-Ni(OH)2 nanoflakes have been synthesized through a hydrothermal route with the assistance of ionic liquid 1-butyl-3-methylimidazolium bromide ([Bmim]Br). The β-Ni(OH)2 nanoflakes are about 100 nm in edge length and 50 nm in thickness. More importantly, [Bmim]Br plays a critical role for the formation of flake-like β-Ni(OH)2 by adsorbing on the OH- ions coordinated with Ni2+ ions on (001) planes. The β-Ni(OH)2 nanoflakes can be converted into NiO via a thermal decomposition process and the obtained NiO nanostructures exhibit a capacity of 1157.6 mAhg-1 at 0.1 C when employed as anode materials in lithium-ion batteries..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
