From batteries to medical applications of graphene in life

   Graphene is known as a "wonder material" due to its excellent properties such as high electrical conductivity, high thermal conductivity, and high strength, and it may revolutionize a large number of applications, including light bulbs, chips, batteries, touch screens, and smartphones and new energy sources. There are countless fields in which graphene can be competent. Let's take a look at the various uses of graphene!

graphene integrated circuits

  Due to graphene's super-strong transmission properties and very good thermal conductivity, graphene is also considered to be a material to replace silicon raw materials. Graphene should not be unexpectedly able to become the next generation of circuit board materials. As early as 2011, a foreign team developed a state-of-the-art "graphene transistor" and integrated the newly researched transistor into a new electronic circuit for experiments. Some of the scientific teams at the company developed the world's first "low noise amplifier monolithic integrated circuit" to fill the gap.

graphene battery

  In the production of batteries, the high-end material that can be used as positive and negative electrodes is none other than graphene. Graphene can also be used as a conductive "additive" added to the positive and negative electrodes to improve the efficiency of the battery and increase the graphene-based battery. In general, the overall efficiency of the battery can be improved. The charging time and charging efficiency of traditional batteries have not been effectively solved, because the development of traditional lead-acid batteries and general traditional lithium batteries has encountered "problems", and new graphene batteries can break through this limitation. At the auto show, some car companies launched graphene lithium titanate batteries, which can achieve fast flash charging within 15 to 20 minutes, and graphene batteries can also be continuously charged and discharged for more than 50,000 times. Cars generally have a cruising range of about 900 kilometers!

Graphene cameras are able to pick up more information from objects around us, allowing us to see things by detecting infrared light.

Graphene touch screen

  The key component of a smartphone is an electrically conductive and very transparent touchscreen. Due to the extremely good flexibility and excellent electrical conductivity of graphene, and its outstanding optical transparency, graphene can be used in the production of mobile phone screens, and graphene is also more efficient than the current material indium tin oxide. for excellent. A foreign research team has developed a flexible screen composed of many layers of graphene and polyester materials. Using this technology, it is also possible to make graphene batteries, controllers such as touch sensors, as well as tablets, as well as materials such as advanced light-emitting diodes.

Graphene Super Material

  American researchers turned soft graphite into a strong "rebar". The process is to convert graphene into a graphene foam material with a three-dimensional structure, and then strengthen the carbon nanotube material with strong mechanical properties and high electrical conductivity to make "enhanced graphene". Researchers in China have used tiny tubular graphene to form cellular foams. It's as light as a balloon but as strong as metal. In the future, it can be used to make bulletproof vests, tank armor, etc.

Graphene memory

  Foreign researchers have been developing storage systems for graphene. Why develop this system? Because the graphene-based storage material system has the characteristics of low manufacturing cost, light weight, low energy consumption, relatively small volume, and large storage space. For example, there is a memory made of graphene titanium dioxide, which is only 55 nanometers long and 7 nanometers thick, and reads and writes almost instantaneously (that is, 5 nanoseconds). With the continuous development of electronic devices such as graphene-based touchscreens and memory, flexible, fully transparent smartphones will become a future reality.

Graphene "artificial throat"

  As we all know, the human throat can only produce sound, but cannot perceive sound. If we can have a material that can both perceive and sound, and has a certain degree of "flexibility", such as making it an "artificial throat", We may be able to solve the language problems of muscle-wasting patients like the late scientist Hawking and even some deaf people. In recent years, scientific researchers in our country have developed this "acoustic device" using graphene research. It emits sound through the thermoacoustic effect and receives the sound signal through the piezoresistive effect.

Versarien's headphones are made with a graphene coating called NaneneGraphene-Enhanced Audio.

Early diagnosis of cancer

  Chinese researchers have discovered for the first time that graphene can help in the early diagnosis of cancer. When abnormal conditions occur in the body, the content of the nucleic acid molecule biomarker cmocrRNA in serum, urine and saliva will also change, but it is difficult to capture by general detection methods. Due to the strong adsorption of graphene, the detection sensitivity can be greatly improved. Through a comprehensive analysis of the captured cmocrRNA, it can be concluded whether the human body has cancer and what kind of cancer, which is of great significance for the early diagnosis and treatment of various cancers.

graphene light bulb

  Now traditional incandescent light bulbs have been gradually replaced by white LEDs. Although LED light sources have various advantages, the price of LED light sources is relatively high, and rare earths are required as manufacturing materials. In the UK, scientists have developed a new graphene light bulb that is stronger and less expensive than LEDs, extending the life of the bulb and reducing energy consumption by a further 10%.

Graphene decontamination sponge

  Researchers use the properties of graphene "sponges" to remove and adsorb various toxic and harmful substances. The adsorption capacity can reach hundreds of times its own weight. After adsorption, it can be recycled after treatment. Chinese scientists evenly wrapped a graphene coating on the surface of ordinary sponges and used its conductivity, hydrophobicity and lipophilicity to absorb oil slicks that leaked on the sea surface.

Seawater Desalination Membrane

  So far, the cost of desalinating seawater is extremely expensive, requires a lot of resources, and causes certain pollution to the environment. British researchers are working on relatively inexpensive graphene oxide membranes for desalination. This is a selective membrane that allows water molecules to pass through and salt ions to filter out. It does not require high temperatures and pressures, making it a low-cost alternative to desalination.



Zeigarnik effect

  As a freelancer, you have to fight procrastination every day. "I've made up my mind many times, but I just can't change it. Is it because I'm slow or slow?". In fact, many procrastinations are irrational. Many obstructions are imagined by myself. So distract, postpone, avoid confrontation. It's cool to procrastinate, and it's cool to procrastinate all the time, so I can't do it. Concentration is also related to physical strength. When the physical strength is exhausted, it is even more difficult to concentrate. You’ll tell yourself: I’m too tired to do this—okay, another perfect procrastination.   In 1927, Bruma Zeigarnik's senior research found that people are more likely to care about unfinished and interrupted work than completed work. This is the Zeigarnik effect. For example, we often don't care much about what we have got, but we will especially cherish what we have worked hard but haven't got. Therefore, the TV series will tell you

Moroccan football team: "The most familiar stranger"

   When I was still in college ten years ago, I led a sightseeing group of more than 30 Moroccan students. Before meeting them, my general impression of the Moroccans was that they are from North Africa but closer to the Arab world. They have religious beliefs, are used to worship, and are inextricably linked with France.   When I saw the real person, I realized that the North Africans in front of me were actually a group of children playing with each other and having fun in time. They were about the same age as me at the time. I have all kinds of nicknames and nicknames. During the process of taking them to Badaling, the Summer Palace and Houhai, two classmates and I, together with more than 30 Moroccan students, realized "cultural integration" and "world unity" in the small group to some extent.   During the World Cup in Qatar, I was surprised to find that the little-known Morocco team, which was eliminated in the group stage of the last World Cup, after miraculou
