Antibacterial hand sanitizers could play a prominent role in slowing down the spread and infection of bacterial pathogens; luteolin (LUT) is potentially useful as an antibacterial component. Therefore, this study elucidated mechanism LUT against Escherichia coli (E. coli) Staphylococcus aureus (S. aureus) developed sanitizer. The results showed that had excellent activity both E.

Abstract Nonvolatile electrical control of magnetism is crucial for developing energy‐efficient magnetic memory. Based on strain‐mediated magnetoelectric coupling, a multiferroic heterostructure containing an isolated magnet requires nonvolatile strain to achieve this control. However, the magnetization response interacting remains elusive. Herein, Co/MgO/CoFeB tunnel junctions (MTJs) exhibiting dipole interaction ferroelectric substrates are fabricated. Remarkably, voltage resistance in...
Magnetic tunnel junction (MTJ) as a key spintronics device can be used for the high-sensitivity magnetic field sensor and high-density non-volatile random access memory (MRAM).
