Furthermore, we realize dependable n-type and ambipolar transistors based on liquid metals with charge transport efficiencies that are comparable to our p-type counterparts, thus providing a foundation for manufacturing integrated circuits and complementary logic gates on flexible substrates. This study ...
Types of Materials材料的类型 Materials may be grouped in several ways. Scientists often classify materials by their state: solid, liquid, or gas. They also separate them into organic (once living) and inorganic (never living) materials.
In general, printing of metals falls into two material formats: building models by fusing metal powders or by the use of metal filaments (wire). The “liquid” origin materials are less common but are still bonded-powder based. While the development has been fast, metal 3D printers are expen...
Study on the form partitioning and content of heavy metals in soil particles with different sizes is crucial for preventing and controlling heavy metals pollution, but few studies regard soil contaminated by heavy metals as a homogeneous body. In this study (Fig. 1), goat manure, lime and phos...
A financial asset is a non-physical, liquid asset that represents—and derives its value from—a claim of ownership of an entity or contractual rights to future payments. Stocks, bonds, cash, and bank deposits are examples of financial assets.

Certain commodities, such as precious metals, are purchased as a hedge against inflation, and the broad set of commodities themselves are an alternative asset class used to help diversify a portfolio. Because the prices of commodities tend to move inversely to stocks, some investors also rely on...
Money market funds are moreliquidthan other investments, meaning you can write checks out of money market accounts just as you would with a checking account. However, once you start writing checks on a money market account, you’ve erased much of its value as an investment. ...
