Scientists analyzed how surface structures like wrinkles and folded networks affect nanoscale friction in multi-layered graphene. Their findings could pave the way for graphene-based solid lubricants and micro/nano-scale mechanical devices.
Intense mid-infrared excitation has been demonstrated as a powerful tool for controlling the magnetic, ferroelectric and superconducting properties of complex materials. Nonlinear phononics is key to this end, as it displaces specific atoms away from their equilibrium positions to manipulate microscopic interactions.
Avoiding complicated preprocessing steps of CVD graphene growth and the required high temperatures of plasma-enhanced CVD (PECVD), researchers have demonstrated the feasibility of direct growth of graphene on gold thin films by PECVD at low temperature.
Researchers have designed and synthesized novel multi-layered, multi-functional nanoparticles that enable a combination of radiotherapy and photodynamic therapy for deep cancer tissue. An initial pre-clinical evaluation of the particles has demonstrated their therapeutic potential.
The huge variety of vdW layered 2D materials provides a large potential for advanced 2D nanoelectronics. However, for scalable applications, all vdW layered 2D materials face a common challenge: transitioning from micrometer-scale 2D flakes to wafer-scale. This is necessary for scaling up 2D vdW materials application in the high-end semiconductor industry. A new review describes the structures, properties, wafer-scale growth methods, and applications of a number of representative vdW ...
