**: Data treasure.
The Year of the Dragon is off to a good start! There are new discoveries in graphene nanomaterials.
On the first trading day after the Spring Festival in the Year of the Dragon, the A** field ushered in a good start. Shanghai Composite Index**156%, rushing to 2900 points, the daily line to achieve four consecutive yang.
On the disk, more than 4,200 ** are red, of which nearly 300 shares have risen by more than 10%, and 2 Beijing Stock Exchange ** Tianfang Standard and Yunchuang Data have gained a 30cm price limit.
Stimulated by a series of good news during the Spring Festival holiday, science and technology themes broke out across the board, with multimodal AI, AIGC, CPO, CHATGPT, computing power leasing and other sectors leading the gains.
The performance of the multimodal AI concept is the most eye-catching, and many stocks such as concept stocks such as Chinese**, Xuanya International, Huina Technology, Yidiantianxia, and Danghong Technology have gained a 20cm price limit.
There are new discoveries in graphene nanomaterials.
There is also good news on the new materials. According to Science & Technology**, British researchers have published an important finding: the first clinical trial of tightly controlled exposure in humans has shown that inhalation of certain types of graphene does not have short-term adverse effects on lung or cardiovascular function. This means that graphene, a nanomaterial, can be safely further developed without posing a significant risk to human health. Related** was published Feb. 16 in the journal Nature Nanomaterials.
In this human trial, ultra-pure graphene oxide nanosheets (a material that blends with water) were used. Researchers from the University of Edinburgh and the University of Manchester recruited 14 volunteers who participated in the study under tightly controlled exposure and clinical monitoring conditions. The results showed that inhalation of ultra-pure graphene oxide had no adverse effects on lung function, blood pressure, or most other biological parameters.
The researchers noted that there were slight indications that inhaling the substance might affect the way blood clots, but the effect was very small. However, further investigation is needed to determine the potential effects of higher doses and prolonged exposure to graphene.
Nanomaterials such as graphene are promising, but they must be manufactured in a safe way to be more widely used in life, the researchers said. A big step forward in understanding how graphene affects the human body by exploring the safety of this unique material in human volunteers. This discovery could open the door to the development of new devices, advanced means and monitoring technologies.
Graphene is expected to leverage the trillion-level industrial chain.
Graphene, known as the "king of new materials", is one of the thinnest nanomaterials in nature, with the highest hardness and the best thermal and electrical conductivity.
In recent years, a number of breakthroughs have been made in the research of graphene materials. At the beginning of January this year, CCTV Finance reported that a research team composed of Georgia Institute of Technology and Tianjin University in the United States created the world's first functional semiconductor made of graphene. Measurements show that graphene semiconductors have 10 times the mobility of silicon, and its birth opens a new door to break through the performance limits of traditional silicon-based semiconductors.
According to Science and Technology**, in November 2023, physicists at the Massachusetts Institute of Technology in the United States turned graphite or pencil leads into "** materials" by separating 5 layers of ultra-thin graphene flakes stacked in a specific order, and by adjusting the resulting material, it can show 3 important properties that have never been seen in natural graphite, including insulation, magnetism or topology.
In April 2023, according to China Science News, Andre Geim and colleagues at the University of Manchester in the United Kingdom found that graphene has unprecedented magnetic resistance at room temperature.
In the context of a new round of industrial upgrading and scientific and technological revolution, the new materials industry is regarded as the cornerstone and forerunner to promote the development of high-tech industries in the future, and will have a broad and profound impact on the development of the global economy, science and technology, environment and other fields.
According to the official website of the Chinese Academy of Sciences, Liu Zhongfan, an academician of the Chinese Academy of Sciences, has said that the "versatile" nature of graphene makes people have endless imagination of its broad application prospects, and some scientists believe that one of the biggest disruptive events of the future technological revolution may be graphene instead of silicon to become the basic material of information technology, and graphene may also shine in the fields of energy, transportation, aerospace, flexible electronics and health care. China is a big country in graphite resources, and it is also one of the most active countries in graphene research and application development.
A number of graphene concept stocks have high growth potential.
According to Databao, up to now, a total of 60 graphene concept stocks have disclosed their 2023 performance express reports and performance forecast data. According to the performance express report and the lower limit of the forecast net profit, the net profit of 10 shares doubled, including Xiongsu Technology, General Motors, China Super Holdings, Huakong SEG, Tianfu Energy, etc.
Xiongsu Technology's net profit growth rate ranks first, and the company expects a net profit of 0$2.3 billion to 03.1 billion yuan, a year-on-year turnaround; During the reporting period, the company's raw materials decreased year-on-year, accounts receivable were better, and the impairment of accounts receivable decreased year-on-year.
From the perspective of future growth potential, according to the consensus of 5 or more institutions**, there are 21 concept stocks that are expected to have a net profit growth rate of more than 20% in 2024 and 2025.
As of February 19**, among these concept stocks, Aiko shares, Shanshan shares, Silicon Treasure Technology, and Megmeet have a rolling P/E ratio of less than 20 times.
Compared with the latest ** price and the institutional consensus ** target price, the space of 11 shares ** is more than 50%, of which the German Nano, Aiko shares, and Stitch ** space are more than 100%.
