Amido‐Amine Co(II) Precursor‐Based Atomic/Molecular Layer Deposition Processes for Cobalt‐Organic Thin Films and Their Thermal Conversion to CoO Thin Films

Advanced Materials Technologies, EarlyView.
Three new atomic/molecular layer deposition processes are developed for Co‐organic thin films using a promising all‐nitrogen‐coordinated cobalt precursor. The study examines film growth, reaction mechanisms, chemical stability, and decomposition pathways of the resulting films through extensive characterization techniques and DFT calculations ...

Subordination properties of P-valent functions defined by integral operators

International Journal of Mathematics and Mathematical Sciences, 2006
By applying certain integral operators to P-valent functions we define a comprehensive family of analytic functins. The subordinations properties of this family is studied, which in certain special cases yield some of the previously obtained results.

MOx/Rh Metallene with Energetic Interfaces as Efficient Bifunctional Electrocatalyst for Durable Water Splitting

Advanced Science, EarlyView.
 . ABSTRACT Developing excellent activity and stability bifunctional electrocatalysts for alkaline water splitting remains challenging. This work constructs ultrathin MOx/Rh metallene heterostructures (M = Fe, Co, Ni) via atmosphere‐controlled solvothermal synthesis, achieving uniform MOx nanoclusters on Rh metallene with optimized interfaces. The FeOx/
