With the ever-increasing demand for power sources of high energy density and stability emergent electrical vehicles portable electronic devices, rechargeable batteries (such as lithium-ion batteries, fuel metal–air batteries) have attracted extensive interests. Among emerging battery technologies, (MABs) are under intense research development focus due to their theoretical level safety. Although significant progress has been achieved in improving performance past decade, there still numerous...
Bacterial cellulose (BC) is an exopolysaccharide with unique properties that has been applied in various fields. However, the dense and intertwined nature of BC fibers limits its use certain applications, including 3D printing scaffolds for bone regeneration. In this work, a controllable BC-based bio-ink was successfully prepared by modifying neat through maleic acid (MA) treatment, aiming to promote tissue To achieve homogeneous dispersions while preserving crystalline chemical properties,...
Reconfigurable intelligent surface (RIS) is considered as a promising technology, which can effectively control the phase of signals with low-cost reflective elements.
