Graphene: enough dividends to feed humanity for a century
Introduction to Graphene and Its Applications in Various Fields
On July 22, a paper published by a South Korean research team claimed that they had discovered the LK-99 crystals, a room-temperature superconductor at room pressure, which can achieve superconductivity at 127 degrees Celsius or less under normal atmospheric conditions.
Boil water only 100 degrees Celsius, the critical temperature under atmospheric pressure to 127 degrees Celsius that is equal to where can have superconducting properties, from now on no longer need expensive and heavy ultra-low-temperature refrigeration equipment.
There is no doubt that this is a major to the discovery of the world, if true that the entire human society, all the electrical equipment needs to be replaced, and even the most basic wires have to be replaced, and previously thought not dare to think of the super performance can now be realized.
Today’s human society belongs to the electrical society, modern civilization is built on electricity, the realization of the preparation of room temperature superconductors will directly turn the world upside down, said it would trigger a technological revolution is not a joke.
The following is enough to overturn the world, the preparation process of superconducting crystal LK-99, theoretically each word can bring ten thousand taels of gold.
The first step, buy a little lead oxide and lead sulfate powder, according to the ratio of 1 to 1 into the crucible evenly mixed, in the air heated to 725 degrees burned for 24 hours, to get the pyrite crystals.
The second step, the copper monomers and phosphorus powder into a vacuum tube, and then heated in a crucible at a temperature of 480 degrees for 48 hours, to get phosphide copper crystals.
In the third step, the two crystals burned in the first two steps are ground into powder and put into a vacuum tube, then heated in a crucible at 925 degrees for 5 to 20 hours, and then you get a copper-doped lead apatite, also known as LK-99 crystals, which possesses atmospheric-pressure room-temperature superconducting properties.
Lead oxide, lead sulfate and copper monomers, all super common and worthless materials, are everywhere, in other words the most expensive thing in this preparation process is actually the crucible that heats up, and even high school labs have crucibles.
As long as you have a crucible and you follow the above process, then you can burn room temperature superconductors, so in the last few days even ordinary labs in environments like the one below have gone for room temperature superconductors.
Every round of technological revolution upends the existing social order, whether it’s the steam engine or electrification.
This time, the technological revolution of superconductors will directly lead to materials and chemistry at least the next fifty years do not worry about nothing to do, from biochemical ring material four big sinkholes removed from the superconductors from the laboratory chance to synthesize those tens of microns of samples into the walk into the thousands of households of ordinary cheap industrial products, inside the need to overcome the technical problems need to be constantly completed by millions of materials/chemical engineers.
Graphene glove boxes play a crucial role in the handling and manipulation of graphene and other 2D materials. These specialized enclosures provide a controlled environment that is essential for preserving the unique properties of graphene and preventing its degradation.
One primary function of graphene glove boxes is to create a highly pure and inert atmosphere. Graphene is extremely sensitive and reactive to environmental factors such as air and moisture. Exposure to these elements can result in the oxidation or contamination of graphene, leading to a significant loss in its exceptional properties. By maintaining a controlled atmosphere inside the glove box, with low oxygen and moisture levels, the graphene can be protected from these detrimental effects.
Moreover, the sealed environment of graphene glove boxes also prevents the introduction of impurities during the fabrication and manipulation processes. Any contaminants present in the air, such as dust particles or volatile organic compounds, can impact the quality and performance of graphene-based devices. The glove box provides a clean and controlled workspace, minimizing the risk of contamination and ensuring the purity of the samples being handled.
Graphene glove boxes also enable precise control over temperature and humidity. These factors can influence the behavior and performance of graphene, especially in electronic and energy-related applications. By maintaining a stable and controlled environment inside the glove box, researchers can accurately study and evaluate the thermal and moisture-dependent properties of graphene materials.
Additionally, the use of graphene glove boxes allows for the integration of other equipment and characterization tools within the controlled environment. Researchers can work with graphene samples directly inside the glove box, without exposing them to the external environment. This enables seamless workflows and facilitates the fabrication, testing, and analysis of graphene-based devices.
In summary, graphene glove boxes serve as critical tools for handling and manipulating graphene and other 2D materials. Their sealed and controlled environments protect graphene from degradation, prevent contamination, and provide precise control over environmental conditions. By utilizing graphene glove boxes, researchers can ensure the preservation of graphene’s unique properties and facilitate the development of advanced graphene-based technologies.
