Abstract Although helical nanofibrous structures have great influence on cell adhesion, the role played by chiral molecules in these cells behavior has usually been ignored. The chirality of nanofibers is inverted odd–even effect methylene units from homochiral l ‐phenylalanine derivative during assembly. An increase adhesion left‐handed and weak behaviors right‐handed are observed, even though both were derived derivatives. Weak negative influences was also observed for left‐ d...

Initial stress (σi) of a room-temperature deposited FePt films was manipulated to study the order-disorder transformation. We observed that, while σi increased from −1.01 (compressive) 0.18 GPa (tensile), phase transformation activation energy decreased 0.387 0.23 eV/atom. This causes reduction in ordering temperature about 100 °C. also found that densification induces an increase tensile 1 before ordering. In with small σi, strong tension facilitates nucleation L10 FePt; however, if highly...

Single-layered FePt thin films were deposited on glass substrates and subsequently annealed at 800 °C for various times in a rapid thermal annealing (RTA) furnace. Near-fully-L10-ordered obtained after RTA. The accumulation of the intrinsic tensile stress is mainly contributed by densification reaction, which leads to development (001) preferred orientation. relief predominantly stems from microstructural variation (from continuous interconnected network state), resulting reduction texture....
