Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

Advanced Materials, EarlyView.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Nonspherical hollow alpha-Fe2O3 structures synthesized by stepwise effect of fluoride and phosphate anions

, 2016
Despite the significant progress in making hollow structures, it is still a challenge to synthesize some specialized hollow structures. In the present work, we obtained a new hollow hematite structure, tube-in-dodecahedron, by using the stepwise ...

Flexural behaviour of concrete slabs reinforced with gfrp bars and hollow composite reinforcing systems [PDF]

, 2018
Solid concrete slabs are very important structural members in building and construction because traditional slabs reinforced with steel carry the load and transfer it to the beam.

Fabrication of hollow lithium titanate material by electrospinning

工程科学学报, 2019
Lithium titanate (Li4Ti5O12, LTO) is an important material to be used as an anode for LIBs (Li+ ion battery). LTO is a zero-strain material (i.e., no structural change occurs during Li insertion/extraction).
