Shifting dynamics of Sino-American competition in multi-aligned Middle East.

The Middle East (ME) is one of the most volatile regions of the world where things can change in the blink of an eye. China, once an ordinary energy customer showing hardly any interest in the politics of the ME, has turned itself into a crucial player in rapidly transforming geopolitical landscape of the ME. The increasing footprints of China in the ME pose challenges to the US interests in the region.

Non-mechanical beam steering for high-speed optical wireless communications via electrowetting on dielectric.

Electrowetting on dielectric (EWOD) is used for non-mechanical optical beam steering (OBS) in optical communication systems. High-capacitance ion gel is used to construct an efficient electrowetting interface that facilitates dynamic OBS. This integration facilitates precise control of beam steering and data transmission efficiency in optical wireless communication systems.
