Special Issue Information

Dear Colleagues,

Low-dimensional materials are those that have at least one dimension small enough at the nanoscale. Examples include quantum dots, nanowires, nanotubes, 2D materials, and 2D polymers. Their geometrical characteristics and mechanical performances, along with rich mechanical-physical-chemical coupling mechanisms have opened up new applications ranging from electronics and energy harvesting to drug delivery. By manipulating their structural or geometric patterns, low-dimensional materials can be further engineered or assembled into low-dimensional structures. Notable examples include defect-engineered 2D materials and twisted van der Waals layered structures. Due to the dimensional constraints, their mechanical performances exhibit drastic contrast with bulk materials. For instance, low-dimensional materials typically are capable of large deformation, which provides excellent opportunities to take advantage of the diverse multiphysics coupling mechanisms between mechanical strains and other physical fields, enabling the design of unconventional functionalities.

This Special Issue aims to present comprehensive research progress on the fundamental understanding of the mechanical performance and the deformation-coupled physical-chemical properties of low-dimensional materials and structures, as well as the rational design strategies to create or enable their novel functionalities. Original research articles or review articles covering theoretical analysis, computation, and experimental approaches are all welcomed.

This paper presents the concrete design of nanowires under the precise size and morphology that play a crucial role in the practical operation of the micro/nano devices. A straightforward and operative method termed as nib-assistance coaxial electrohydrodynamic (CEHD) printing technology was proposed. It extracts the essence of a nib-assistance electric field intensity to enhance and lessen the internal fluid reflux of the CEHD jet. The experiments were performed to add microparticles into the inner liquid to indicate the liquid flow consistency within the coaxial jet. The reflux in the coaxial jet was observed for the first time in experiments. The nanowires with a minimum size of 70 nm were printed under optimum experimental conditions. The nanopatterns contained aligned nanowires structures with diameters much smaller than the inner diameter of nozzle, relying on the coaxial nib-assisted technique. The printed results revealed that the nib-assisted CEHD printing technique offers a certain level high quality for application of NEMS system. Full article
