Recently, the Zhao Zhigang group of the Suzhou Institute of Nanotechnology and Nano-Bionics of the Chinese Academy of Sciences has developed a smart supercapacitor electrode that can acquire the ability to interact with people without complicated circuit design.
Due to its high power density and long cycle life, supercapacitors are considered to be the most promising new energy storage devices. They have great application value and market in many fields such as transportation, power, communication, national defense and consumer electronics. potential.
In recent years, people continue to improve the performance of supercapacitors through new material development, and give them new features and functions, such as lightweight, flexible, woven, etc., so that it can be better applied to real life and production. A bold and inspiring idea was born: Can an innovative supercapacitor be developed and given new intelligence?
The smart supercapacitor electrode exhibits changes in its energy storage state by alternating the pattern and background color.
Supercapacitors can only perform the function of pure energy storage. After being intelligent, they can realize interaction with people. For example, the performance data is converted into graphics or images and displayed on the screen, and interactive processing is performed. This smart supercapacitor developed by Zhao Zhigang's research group can achieve this.
It is reported that the smart supercapacitor is made of tungsten oxide nanowire and polyaniline as electrode active materials, and is formed by patterning. The tungsten oxide is composed of SINANO and polyaniline.
This electrode has a rich color change and excellent capacitance performance, and its energy storage state can be exhibited by the interaction of its pattern and background color - when one component is colored, the other component is transparent. As the energy storage and release process proceeds, the pattern and background color interact accordingly.
According to reports, these studies combine the function of ordinary supercapacitor energy storage with the visible change of electrochromism, giving intelligent new features to supercapacitors, opening a new path for the future development of supercapacitors.
Dressing tables initially started as small portable cosmetic boxes that were filled with little perfume flasks, combs, nail files, tiny scissors, etc.. Women of high status would have their maids carry them out when the Madame would ask for a comb. The French called these ornate boxes `necessaires` (must-haves).
It wash`t until the late 1700s that finally someone placed the box on a table and drew up a chair.
The Dressing Table, as we know it today, was developed in Europe in the beginning of the 17th century. By the 18th century, it became known as a mark of social standing as well as an object of fine design and craftsmanship.
A makeup vanity with drawers can be more than just a space to get dressed. Place your vanity next to your bed and add a chic table lamp for a stylish Bedside Table.
For people who work from home, a makeup vanity with drawers can double as a desk. Just ensure that the vanity is wide enough to accommodate a laptop, and use cable ties to manage cords and wires to keep your room clutter-free. The drawers offer the ideal space for storing office supplies and important documents.
If you have limited space but still want a dedicated area to add the finishing touches to your outfit, a makeup vanity with drawers makes a stunning console for your entryway.Store your makeup and jewelry in the drawers, and keep a beautiful bowl on top of the table as a catch-all for phones, wallets, and keys.
