Abstract: Cholesteric liquid crystals (CLCs), due to their structural rearrangement under external stimulation, offer the potential for various physical and chemical sensing applications. Herein, we ...

Researchers have succeeded in developing the smallest fully autonomous robot in history. It measures less than 1 millimeter and can swim underwater for months powered only by light.

Abstract: This paper presents the design and empirical modeling of a high-sensitivity microwave sensor based on a Rectangular Complementary Split Ring Resonator (RCSRR) integrated into a microstrip ...

But only in the last 70 years have we known for certain they were there. In 1956, physicists Clyde Cowan and Frederick Reines ...
