Abstract: Two-dimensional (2-D) array sets with good 2-D correlation properties have received considerable attention in wireless communication systems. This paper focuses on 2-D Z-complementary array ...

Researchers from the University of Hong Kong studying the structure of electrons in 2D materials have predicted new types of phase transitions that have yet to be seen in experiments Illustration of ...

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you’ll ...

Here’s what you’ll learn in this story: Time might actually have 3 dimensions. But it also means that the space would actually be one-dimensional, instead of the three dimensions we’re familiar with.

In a groundbreaking experiment, researchers from Tsinghua University have proven that two-dimensional (2D) semiconductor materials can withstand the harsh conditions of space. The team, led by ...

In April 1982, Prof. Dan Shechtman of the Technion–Israel Institute of Technology made the discovery that would later earn him the 2011 Nobel Prize in Chemistry: the quasiperiodic crystal. According ...
