The composition can be easily adjusted and modulated by multi-metals. In addition, the well-designed carbon nanocubes effectively promote electronic conductivity and buffer the volume change upon charge and discharge cycling, resulting in good capacity and long-term cycle life for both lithium-ion ...
Transition metals with similar atomic radii to the atomic radius of Zn can be easily doped into the ZnO lattice. Many transition metals, including Fe [3], Co [4], Ni [5], Mn [6], Cr [7], V [8], Cu [9], and Zr [10], have been doped into ZnO to narrow its bandgap [11]...

For instance, hydrogenolysis or oxidation of lignin β-O-4 model compounds catalyzed by transition metals affords monophenols for subsequent amination processes using organic or inorganic N-sources via one or multiple steps to produce different N-containing compounds (Routes 1–3 in Fig. 1). In ...
Transition metals are required trace nutrients that foster inter-microbial competition when limited, inhibit bacterial growth through host sequestration, or induce toxicity in excess. This review highlights recent evidence that transition metals influence multiple stages of C. difficile colonization and that...
