Environment-friendly antisolvents are critical for obtaining highly efficient, reproducible, and sustainable perovskite solar cells (PSCs). Here, we introduced a green mixture antisolvent of ethyl ...

For 3D walking control of a biped robot we analyze the dynamics of a 3D inverted pendulum in which motion is constrained to move along an arbitrarily defined plane. This analysis yields a simple ...

In this communication, a broadband circularly polarized slot antenna with an inverted-F-shaped microstrip feed line and two linked rectangular slots in the ground plane is proposed.
