The myozenin family of proteins binds calcineurin, which is involved in myocyte differentiation of skeletal muscle. Moreover, gene expression of myozenin is closely related to meat quality. To further understand the functions and effects of myozenin2

Mode selection and power extraction are the core of single-mode semiconductor lasers, but generally, they restrict each other. A large gain area with high radiation efficiency is necessary for high output power but will induce more competitive modes

Wide gamut and angle-insensitive structural colors are highly desirable for many applications. Herein, a new type of lithography-free, planar bilayer nanostructures for generating structural colors is presented, which is basically composed of a deep-

We report the control of an emission direction in two-dimensional (2D) angular space for the terahertz master-oscillator power-amplifier quantum cascade lasers. The device exploits a rhombohedral array of subwavelength air slits as the wave coupler.

We report the realization of terahertz quantum cascade laser based on an antenna array, in which each unit contains two dipole antennas with slightly different widths. The device operates in single mode around 3.2THz, and the radiation efficiency can
