Tungsten oxide nanowires are a fantastic one-dimensional material, which is rarely introduced on academic websites. It may not be known to many that tungsten oxide nanowires can also be used as absorbing materials for radar electromagnetic waves, such as stealth fighter coatings, strategic missile concealment and so on.

In the field of energy, supercapacitor is a new type of energy storage device with rapid development in recent years. Its performance is between traditional capacitor and secondary battery. It has the characteristics of high power, fast charging and discharging rate, long cycle life, wide operating temperature range, good safety performance and economic and environmental protection. They are widely used.

Quantum dots are zero-dimensional nanomaterials consisting of a small number of atoms. In recent years, quantum dots (QDs), as a new type of nanomaterials with unique physical properties, have attracted extensive interest of researchers at home and abroad. Their research contents involve physics, chemistry, materials and other disciplines, and have become a new interdisciplinary subject.

Supercapacitors are energy storage devices between batteries and traditional capacitors. Because of its high charging and discharging efficiency, high power density, long cycle life and friendly environment, it is widely used in transportation, mobile communications, information technology, aviation, aerospace and national defense science and technology.
