In this work, we made an attempt to combine 2 materials of such kind (showing the desired electrochemical activ- ity), which (according to the information available to us) have not yet been tested as a closed battery system. In addi- tion to fullerenes in this experiment we chose lithium...
Recent advances in materials science have fueled tremendous interest in numerous potential biomedical applications of various nanomaterials. For example, fullerene C60 molecules are unique for their multi-functional uses in materials science and optics [1–4], and are considered for a variety of biologi...
