2D/2D BiSe/SnSe heterostructure with rapid NO gas detection.

Heterostructure engineering is crucial for enhancing gas sensing performance. However, achieving rapid response for room-temperature NO sensing through rational heterostructure design remains a challenge. In this study, a BiSe/SnSe 2D/2D heterostructure was synthesized by hydrothermal method for the rapid detection of NO at room temperature.

Effects of Zr-Cu Alloy Powder on Microstructure and Properties of Cu Matrix Composite with Highly-Aligned Flake Graphite.

Highly-aligned flake graphite (FG) reinforced Cu matrix composites with high thermal conductivity and adaptive coefficient of thermal expansion were successfully prepared via the collaborative process of tape-casting and hot-pressing sintering. To overcome the problem of fragile interface, Zr-Cu alloy powder was introduced instead of pure Zr powder to enhance the interfacial strength, ascribed to the physical-chemical bonding at the Cu-FG interface. The results indicate that the synthetic ZrC as interfacial phase affects the properties of FG/Cu composites.

Challenges and future perspectives on microwave absorption based on two-dimensional materials and structures.

The widespread use of electronic equipment, such as computers, cell phones, communication devices and wireless facilities, has increased electromagnetic radiation, which can cause cancer and other diseases in humans. Furthermore, there is an urgent need for excluding the interferences in the aircraft and other precise instruments in military aspects. Therefore, minimizing and attenuating electromagnetic waves are critical issues.
