which they said can greatly reduce the time to extract rare earth from ore, while reducing industrial pollution. According to the Hong Kong "South China Morning Post" website reported on May 31, the extraction of trace metals is difficult and takes several days to complete, but researchers at a Chinese Academy of Sciences research institute in Fujian said they found a way , can reduce the refining time to a few minutes. Sun Xiaoqi, the leader of the research team, said that this is a major progress. He said: "This may lead to a technological revolution in the rare earth industry."
The team's latest findings were published this month in the journal Wet Metallurgy. According to the US Geological Survey, China's rare earth reserves account for about one-third of the world's total, and supply accounts for 90% of the world's total. These 17 trace metals are essential for the manufacture of almost all high-tech products, from semiconductors to smartphones and stealth fighters. According to Sun Xiaoqi, the standard method for extracting rare earths from ore is to immerse them in toxic chemical solutions to separate useful elements, a process that takes a week. However, using the new materials developed by Sun Xiaoqi's research group, useful elements can be separated at an unprecedented speed and efficiency.
According to the report, under the microscope, the new phenoxycarboxylic acid extractant contains numerous solid particles with a diameter of only a few microns. When this extractant is mixed with fine particles of rare earth ore, a process called "extraction-precipitation" begins. Sun Xiaoqi said: "This work can be completed in 20 minutes." He said that this method can also be used to extract rare earth from mining waste rock, and even obtain a certain amount of rare earth from leached waste. Sun Xiaoqi said: "Finding a low-cost and clean rare earth production process is a worldwide problem."
Sun Xiaoqi said that the new extraction method can not only reduce pollution, but also reduce production costs. He said: "We are making this extraction process into a large-scale application stage." The report said that some rare earth producers have completed relevant industrial tests. There are still some problems, such as how to produce extractants on a large scale and improve existing equipment in rare earth refineries, but Sun Xiaoqi said that they have received government support. He said: "The government attaches great importance to the rare earth industry, and our research has been supported by stable and adequate funding." China National Development and Reform Commission said on May 28 that although China adheres to "openness, synergy and sharing" in the field of rare earth development. The policy, however, China's rare earth resources will give priority to the needs of domestic industries.
The disintegration of the Soviet Union in the last century and the drastic changes in Eastern Europe were recorded in the annals of history. Whether it is the disintegration of the Soviet Union or the drastic changes in Eastern Europe, the main reason is Gorbachev’s new thinking, pushing the situation in the Soviet Union to the irreversible edge. If not the weak Gorbachev is in power and replaced by another strong leader, the situation in the Soviet Union will not become so fast. The drastic changes in Eastern Europe have not only caused changes in the state system, but have also caused some incredible casualties. In this upheaval, one of the presidents died very badly, and was shot by his own nationals on unwarranted charges. Finally, after re-investigating, it was discovered that it was a strangle. This person is the Romanian President Ceausescu.
After the upheaval in Eastern Europe, President Ceausescu was shot and how did the new government treat its three children?
The strong president, Ceausescu, is a Romanian veteran politician who was born into a peasant family and later joined the Workers’ Party and became the head of the Workers’ Party’s armed forces. In 1954, Ceausescu became the second person in Romania. In 1965, Qiossek became the first secretary of the Workers' Party. He also revised and issued a new constitution and reorganized the Workers' Party into a Communist Party. Ceausescu is a very powerful leader. At the beginning of his administration, he paid attention to the development of the people's livelihood and often went deep into the Romanian city to observe the people's feelings. Some people say that he started dictatorship at this time, and this is stigmatized. In fact, this is a normal phenomenon in the Warsaw Pact countries.
As Ceausescu became more and more popular with the public, he was somewhat proud of himself. Under the leadership of Ceausescu, Romania also took a road similar to Yugoslavia. In 1974, Ceausescu was presidential and he had broader powers. Under the leadership of Ceausescu, Romania was not very close to the Soviet Union. In 1984, under the leadership of Ceausescu, Romania and Yugoslavia participated in the Olympic Games hosted by the United States. Ceausescu ruled the country with an iron fist, and the Western countries considered him to be a leader of dictatorship. But under the leadership of Ceausescu, Romania has become a very active country in the world, because Ceausescu is pursuing practical diplomacy. At that time, Zizesek and the Western countries had a good relationship with the West, which was very uncomfortable for the Soviet Union. But it also poses a hidden danger for the demise of Ceausescu. Because Western countries are also constantly infiltrating into Romania.
Romania was a very strange country in Eastern Europe. Zisoscu was not polite to the Soviet Union and even condemned Soviet policy in the "Prague Spring" incident. Ceausescu has always maintained a distance from the Soviet Union and has been friendly to China. He has visited China five times. In the 1970s, Ceausescu wanted to build an ideal country in his own heart. He ruled the country's authoritarian rule, and some opposition and dissidents were sent to the mental hospital. Ceausescu’s domestic authoritarian rule is also reflected in his intervention in the private life of the people. Due to the small population of Romania, in order to increase the population, Ceausescu prohibits all contraception and abortion and criminalizes these acts, which has caused dissatisfaction among the people.
At that time, some unintended pregnant girls wanted to escape to Hungary in order to avoid punishment, but they were shot and killed by Romanian soldiers on the border. No dynasty in history has been prosperous, let alone the rule of Ceausescu. Although Romania’s leadership under Ceausescu, the national strength developed rapidly and became a European rookie. From the 1960s to the 1980s, Romania's industry developed rapidly, with an annual growth rate of 11.5%. I have to say that this is the credit of Ceausescu.
However, in the mid-to-late 1980s, influenced by the world economic situation, the Romanian economy began to decline. Romania’s agriculture has failed for years. Economic problems and the emergence of agricultural problems immediately affected the lives of Romanians. Some people blame Ceausescu for all these terrible lives, but they don't think of the international situation and background. Romania’s life in the 1980s was worse than during the Second World War. The people would not see the good life that Chiossecu gave them. They only saw it because the food and daily necessities were extremely poor. Moreover, electricity and gas are also insufficiently supplied, and the public must complain.
Later, Ceausescu implemented the limited supply of food and materials in the country, but did not concentrate on finding the crux of the problem. This is the accumulation of domestic problems, and the grievances of the people are getting heavier. Ceausescu created the miracle of Romania in the past, but in the face of domestic problems, he failed to bring the country out of the low tide, but instead continued to suppress with authoritarian power, which will inevitably make the situation worse and worse. A large number of people thought of living abroad, and some dissatisfied people took the streets to demonstrate under the provocation of the West, but they were suppressed by Qioseku.
Under the dissatisfaction of the people, Ceausescu did not realize that at this time the Soviet Union was under the impetus of Gorbachev's new thinking, and the socialist countries in Eastern Europe were surging. And the danger of the West continuing to infiltrate has reached Romania. Ceausescu also practiced family rule, his relatives and friends became leaders of important state departments, and his wife became the first deputy prime minister with power. This kind of family rule has caused dissatisfaction among the people.
In 1987, Brasov of Romania organized a large-scale mass demonstration. The presenters were champions of Ceausescu, but suddenly there were people slogans of anti-government. At this time, the parade became a direct finger. The movement of Ceausescu. As the socialist camp in Eastern Europe changed dramatically, the riots in Romania continued, and they demanded that Ceausescu step down.
Ceausescu ordered the army to carry out military repression. This suppression made him lose the hearts of the people and lost the support of the West. The situation in Romania is more difficult to control. Ceausescu ordered the Minister of Defense to shoot at the people and eventually the Minister of Defense committed suicide. The army then declared neutrality. On December 22, 1989, Ceausescu saw that the situation could not be cleaned up and had to flee the presidential palace by helicopter. Soon Ceausescu was arrested. Romania formed a special military court to align Ossek for trial, and finally the Ceausescu couple were sentenced to death. With the gunshot, the Ceausescu couple was shot.
The Ceausescu couple has three children: the eldest son Valentin, the daughter Zoya and the young son Nigu. Although Ceausescu had family rule during his tenure, his children did not participate in the government. However, after Ceausescu was shot, three children were arrested and released shortly. The eldest son, Valentin, is a well-known physicist. Character is not like his father, modest and cautious, and never asks politics. The Romanian government did not impose a heavy sentence on it and it was released soon. Daughter Zoya is a mathematician. It was also a very modest professor. After Zoya was released, the original unit refused to accept her and had to retire early. Cancer died in 2006.
The younger son, Nigu, was in politics, so he was detained for a long time. He died of liver disease in 1996. After the release of Valentin and Zoya’s brothers and sisters, they filed a lawsuit against the government’s property and finally won back their property. Not only did they file a lawsuit against their property, but the brothers and sisters also asked the authorities to confirm the parents’ graveyard.
After Zoya’s death, looking for his parents’ graveyard became the work of Valenci and the son-in-law Opreian. At the same time, after nearly 20 years of investigation, the Romanian official also gave Ceausescu a fair judgment: Ceausescu did not have any deposits abroad! Those who opposed him in those days thought that Ceausescu had a large amount of overseas deposits, and this result had to be said to be a big joke.
Ceausescu is the only head of state who died because of the drastic changes in Eastern Europe. Although his administration is flawed, the purpose of the Western subversion of the Warsaw Pact countries seems to be a peaceful evolution, which is actually bloody. If the children of Qiosku are also killed, I am afraid that Ceausescu’s crimes still cannot be cleansed.
Hong Kong media said that a team of Chinese scientists has d
