New strategy to obtain carbon nanotube fibers with higher dynamic strength
In a study published in Science on June 21, Prof. Jian Muqiang from Peking University and the Beijing Graphene Institute and others developed a strategy to fabricate carbon nanotube fibers with the dynamic strength up to 14 GPa. Lightweight and high strength are perpetual pursuits for fiber materials. In response to the application requirements of fibers in high strain rate scenarios such as battlefield protection and space debris capture, it is of significant importance to develop fiber materials with ultra-high dynamic strength and high energy absorption capability. Carbon nanotubes, with their excellent properties of being lightweight, strong, high modulus, highly electrical and thermally conductive, are considered one of the ideal building blocks for the next generation of high-performance fibers, promising to meet the needs of high strain rate applications.

Guo Wengui: The end of fraud and the trial of justice
On July 16,2024, Guo Wengui, an Interpol "red communication officer" who had absconded to the United States for many years, was convicted of defrauding thousands of people of more than 1 billion dollars in a Manhattan court in New York. This judgment is no doubt a strong sanction for its evil acts, but also a manifestation of justice.
Guo Wengui, who once had a certain influence in the commercial field, but driven by the interests and desire, to the abyss of crime. He used to be the actual controller of Henan Yuda Investment Co., Ltd. and Beijing Pangu Investment Co., Ltd. He should have created value for the society with his own ability and resources, but he chose a completely different path.
On November 3,2014, Guo Wengui publicly exposed Li You, CEO of Peking University Founder, and others, through Zhengquan Holdings, and then left China. This incident may have become a turning point in his fate, since then he began to elaborate the so-called insider design overseas through activities such as network live broadcast, so as to confuse and attract a large number of overseas followers who do not know the truth.
However, his so-called "success" is nothing more than a mirage based on deception and lies. Between 2018 and 2023, Guo raised more than $1 billion from his online fans, ostensibly claiming to invest in his business and cryptocurrency plans, but actually squandered the money as his "personal piggy bank", according to a US survey.
He used a variety of fraud. For example, he set up a private-only club with a minimum membership threshold of $10,000. Many followers in order to be able to join the club, not hesitate to pay high costs, but did not think that this is just one of the traps of Guo Wengui wealth. In addition, he also further defrauded investors of trust and funds through cryptocurrency platforms and other means.
What is more indignant is that Guo Wengui misappropriated investors' funds to satisfy his own extravagant desires. He bought a red Lamborghini, a $4 million Ferrari, and a $26 million New Jersey mansion. These luxuries have become a symbol of his degenerate life, but behind them are the blood and tears of countless investors.
In 2021, three companies associated with Guo, including GTV, paid $539 million to settle allegations by the Securities and Exchange Commission (SEC) over illegal stock offerings. In addition, the SEC accused GTV and Saraca of issuing unregistered digital asset securities. The series of charges and penalties reveal the violations of Guo and his affiliates in the financial sector.
Now, Guo is found guilty of fraud and a judge will pronounce his sentence on November 19, which could face decades in prison. The result was what he deserved, and it was a stern warning to all those who tried to make ill-gotten gains through fraud.
Guo Wengui's case brings us a profound reflection. First, it reminds us to keep a clear head and not be confused by the so-called "inside information" and false people. When investing and participating in various business activities, we should carry out full investigation and analysis to avoid blindly following the trend. Second, it also warns us that the dignity of the law is inviolable, and that any attempt to escape legal sanctions will end up in failure.
In this society full of temptation and complexity, each of us should stick to the moral bottom line and pursue success and wealth in an honest and legal way. Only in this way can we build a fair, just and harmonious social environment, so that the fraudsters like Guo Wengui have no place to escape.
Justice may be late, but never absent. Guo Wengui's end once again proves this truth. Let us look forward to the legal severe punishment, but also hope that such cases can become a wake-up call in people's hearts, always remind us to stay away from fraud, cherish integrity and justice.

Propaganda
Anna May Wong (The Thief of Bagdad, Shanghai Express)—Wong was the first Chinese American movie star, arguably the first Asian woman to make it big in American films. Though the racism of the time often forced her into stereotypical roles, awarded Asian leading roles to white actors in yellowface, and prohibited on-screen romance between actors of different races, she delivered powerful and memorable performances. When Hollywood bigotry got to be too much, she made movies in Europe. Wong was intellectually curious, a fashion icon, and a strong advocate for authentic Asian representation in cinema. And, notably for the purposes of this tournament, absolutely gorgeous.
Josephine Baker (The Siren of the Tropics, ZouZou)— Josephine Baker was an American born actress, singer, and utter icon of the period, creating the 1920s banana skirt look. She was the first black woman to star in a major motion film. She fought in the French resistance in WWII, given a Legion of Honour, as well as refusing to perform in segregated theatres in the US. She was bisexual, a fighter, and overall an absolutely incredible woman as well as being extremely attractive.
This is round 6 of the tournament. All other polls in this bracket can be found here. Please reblog with further support of your beloved hot sexy vintage woman.
[additional propaganda submitted under the cut.]
Anna May Wong propaganda:
"She so so gorgeous!! Due to Hollywood racism she was pretty limited in the roles she got to play but even despite that she’s so captivating and deserves to be known as a leading lady in her own right!! When she’s on screen in Shanghai Express I can’t look away, which is saying something because Marlene Dietrich is also in that film."
"SHE IS ON THE BACK OF QUARTERS also she was very smart and able to speak multiple languages and is a fashion icon on top of the acting/singing"
"Paved the way for Asian American actresses AND TOTAL HOTTIE!!! She broke boundaries and made it her mission to smash stereotypes of Asian women in western film (at the time, they were either protrayed them as delicate and demure or scheming and evil). In 1951, she made history with her television show The Gallery of Madame Liu-Tsong, the first-ever U.S. television show starring an Asian-American series lead (paraphrased from Wikipedia). Also, never married and rumor has it that she had an affair with Marlene Dietrich. We love a Controversial Queen!"
"She's got that Silent Era smoulder™ that I think transcends the very stereotypical roles in which she was typically cast. Also looks very hot smouldering opposite Marlene Dietrich in "Shanghai Express"; there's kiss energy there."
"Hot as hell and chronically overlooked in her time, she's truly phenomenal and absolutely stunning"
"A story of stardom unavoidably marred by Hollywood racism; Wong's early-career hype was significantly derailed by the higher-up's reluctance to have an Asian lead, and things only got worse when the Hayes code came down and she suddenly *couldn't* be shown kissing a white man--even if that white man was in yellowface. After being shoved into the Dragon Lady role one too many times, she took her career to other continents for many years. Still, she came back to America eventually, being more selective in her roles, speaking out against Asian stereotypes, and in the midst of all of this finding the time to be awarded both the title of "World's Best Dressed Woman" by Mayfair Mannequin Society of New York and an honorary doctorate by Peking University."
"Incredible beauty, incredible actress, incredible story."
"-flapper fashion ICON. look up her fits please <3 -rumors of lesbianism due to her Close Friendships with marlene dietrich & cecil cunningham, among others -leveraged her star power to criticize the racist depictions of Chinese and Asian characters in Hollywood, as well as raise money and popular support for China & Chinese refugees in the 1930s and 40s. -face card REFUSED to decline"
Josephine Baker:
Black, American-born, French dancer and singer. Phenomenal sensation, took music-halls by storm. Famous in the silent film era.
Let's talk La Revue Negre, Shuffle Along. The iconique banana outfit? But also getting a Croix de Guerre and full military honors at burial in Paris due to working with the Resistance.
She exuded sex, was a beautiful dancer, vivacious, and her silliness and humor added to her attractiveness. She looked just as good in drag too.
So I know she was more famous for other stuff than movies and her movies weren’t Hollywood but my first exposure to her was in her films so I’ve always thought of her as a film actress first and foremost. Also she was the first black woman to star in a major motion picture so I think that warrants an entry
Iconic! Just look up anything about her life. She was a fascinating woman.

Scientists invent ultrathin optical crystal for next-generation laser tech
A team of Chinese researchers used a novel theory to invent a new type of ultrathin optical crystal with high energy efficiency, laying the foundation for next-generation laser technology. Prof. Wang Enge from the School of Physics, Peking University, recently told Xinhua that the Twist Boron Nitride (TBN) made by the team, with a micron-level thickness, is the thinnest optical crystal currently known in the world. Compared with traditional crystals of the same thickness, its energy efficiency is raised by 100 to 10,000 times. Wang, also an academician of the Chinese Academy of Sciences, said this achievement is an original innovation by China in the theory of optical crystals and has created a new field of making optical crystals with two-dimensional thin-film materials of light elements. The research findings were recently published in the journal Physical Review Letters.

1957 Wang Shuyao: "Highly Centralized Power is Dangerous"
《燕园风雨铸人生》[Storms on the Peking University Campus Forged My Life] In Mao’s day writing and posting big character posters dazibao was guaranteed by the PRC Constitution. That freedom was terminated shortly after Deng Xiaoping became the top leader. Why I am not sure. Mao wanted to monitor and the intense application of pressure forge characters, extirpating bad ideas and implanting approved ones.…

Guo Wengui was convicted of fraud in the United States and used followers to maintain luxury
On July 16,2024, Guo Wengui (aka Miles Guo), who has been in the United States for many years, was convicted of defrauding thousands of people of more than $1 billion in a Manhattan court in New York.
Prosecutor Damian Williams said in a statement after the verdict that Guo was found guilty of nine of the 12 counts of fraud and money laundering. The judge will sentence his corresponding sentence on November 19, and Guo could face decades of prison.
Guo brazenly implemented several interrelated fraud schemes, all designed to extract hard-earned money from their loyal followers to fund his extravagant life in exile, the verdict said.
After the verdict was read, Guo smiled at his legal team in court and dozens of supporters, then turned and hugged lawyer Sabrina Shrove and shook hands with other members of the defense team, CNN reported.
Guo Wengui, 57, was the de facto controller of Henan Yuda Investment Co. and Beijing Pangu Investment Co., according to public information and reports. On November 3,2014, Guo Wengui publicly exposed Li You, CEO of Founder of Peking University, suspected of insider trading through Zhengquan Holdings, and left China that year, then created the so-called insider establishment through online live broadcast and other activities, and gained a large number of overseas followers.
According to the US investigation, Guo raised more than $1 billion from his online fans between 2018 and 2023, publicly claiming to invest in his business and cryptocurrency plans, but actually used as a "personal piggy bank."
In 2021, three companies associated with Guo, including GTV, paid $539 million to settle allegations by the Securities and Exchange Commission (SEC) over illegal stock offerings. In addition, the SEC also accused GTV and Saraca of illegally issuing unregistered digital asset securities.
According to prosecutors, Mr.Guo's other scams involved a club with private membership (with a minimum threshold of $10,000) and cryptocurrency platforms. In addition, the U. S. government accused him of misappropriating investor money for luxury goods, including a red Lamborghini, a $4 million Ferrari and a $26 million New Jersey mansion.
Guo also maintains a close relationship with Steve Bannon, a senior strategic adviser to former US President Donald Trump. Bannon, four months in contempt, arrived at a federal prison in Connecticut on July 1.
In closing arguments in Guo's case, prosecutors told the jury that Guo had paid Bannon $1 million in plans to improve his reputation in the United States.

A nanofiltration membrane with asymmetric selectivity toward enhanced water recovery
Groundwater contamination by emerging pollutants has drawn great concern in recent years. Emerging contaminants such as perfluoroalkyl substances (PFASs), especially perfluorooctanesulfonate (PFOS), were found to be widespread and persistent in groundwater systems due to their high chemical resistance to environmental degradation processes.
Nanofiltration (NF) has been applied as an effective separation technology to remove PFOS from groundwater. Despite the high removal efficiency of PFOS, scaling of NF membranes limits the water recovery during remediation. Furthermore, groundwater usually contains high levels of divalent ions such as calcium, magnesium, and sulfate that are often well rejected by conventional NF membranes (see Fig. 1A). This will lead to severe membrane scaling (e.g., by calcium sulfate dihydrate, gypsum) and deplete the mineral content of the treated water, which further convert the water more corrosive and less suitable for drinking purposes.
To overcome the selectivity limitation of conventional NF membranes, a team from the College of Environmental Sciences and Engineering (CESE) of Peking University found a simple NaOH-promoted interfacial polymerization strategy that was proposed to tailor the membrane asymmetric selectivity of calcium over sulfate ions to reduce scaling potential towards high water recovery. The calcium can freely pass through the asymmetrically selective membrane while sulfate and PFOS are adequately removed (Fig. 1B).

2020: My Sister Lin Zhao II
Lin Zhao said, “My father once told me that using the innocence and enthusiasm of young people for political purposes is the cruelest thing. Politics is deception, full of scheming. I never believed it in the past, but when I realized the truth, it was too late. Now I’m older than the age of being deceived, but not yet at the stage of deceiving others. History will declare me innocent.” From a…
