Design, synthesis and applications of functional zirconium-based metal-organic frameworks

In a review led by Prof. Zhijie Chen's group from Department of Chemistry at Zhejiang University, an overview of recent progress in the development of Zr-MOFs is provided. The article titled "Design, synthesis and applications of functional zirconium-based metal-organic frameworks" is published in the journal Science China Chemistry. The authors summarize how reticular chemistry can be applied to the design, synthesis, and applications of some representative Zr-MOFs. Furthermore, the authors also provide an outlook on the future development of Zr-MOFs. The authors first introduce reticular chemistry and how it can be applied to the rational design and synthesis of Zr-MOFs to achieve the targeted structure and/or properties. Synthetic strategies, including isoreticular expansion, linker functionalization, node functionalization, post-synthetic modification, and defect engineering, are then discussed in the context of applications.

New proof for black hole spin

The supermassive black hole at the heart of galaxy M87, made famous by the first picture of a black hole shadow, has yielded another first: the jet shooting out from the black hole has been confirmed to wobble, providing direct proof that the black hole is spinning. Super massive black holes, monsters up to billions of times heavier than the Sun that eat everything around them including light, are difficult to study because no information can escape from within. Theoretically, there are very few properties that we can even hope to measure. One property that might possibly be observed is spin, but due to the difficulties involved there have been no direct observations of black hole spin. Searching for evidence for black hole spin, an international team analyzed over two decades of observational data for the galaxy M87.  This galaxy located 55 million light-years away in the direction of the constellation Virgo harbors a black hole 6.5 billion times more massive than the Sun, the same black hole which yielded the first image of a black hole shadow by the Event Horizon Telescope (EHT) in 2019. The supermassive black hole in M87 is known to have an accretion disk, which feeds matter into the black hole, and a jet, in which matter is ejected from near the black hole at close to the speed of light. The team analyzed data for 170 time frames collected by the East Asian VLBI Network (EAVN), the Very Long Baseline Array (VLBA), the joint array of KVN and VERA (KaVA), and the East Asia to Italy Nearly Global (EATING) VLBI network. In total, more than 20 radio telescopes across the globe contributed to this study. The results show that gravitational interactions between the accretion disk and the black hole’s spin cause the base of the jet to wobble, or precess, much the same way that gravitational interactions within the Solar System cause the Earth to precess. The team successfully linked the dynamics of the jet with the central supermassive black hole, providing direct evidence that the black hole does in fact spin. The jet’s direction changes by about 10 degrees with a precession period of 11 years, matching theoretical supercomputer simulations conducted by ATERUI II at the National Astronomical Observatory of Japan (NAOJ). "We are thrilled by this significant finding," says Yuzhu Cui, lead author on the paper summarizing the research she started as a graduate student at NAOJ before moving to Zhejiang Lab as a postdoctoral researcher. "Since the misalignment between the black hole and the disk is relatively small and the precession period is around 11 years, accumulating high-resolution data tracing M87 structure over two decades and thorough analysis are essential to obtain this achievement.” "After the success of black hole imaging in this galaxy with the EHT, whether this black hole is spinning or not has been a central concern among scientists," explains Dr. Kazuhiro Hada from NAOJ. "Now anticipation has turned into certainty. This monster black hole is indeed spinning." “This is an exciting scientific milestone that was finally revealed through years of joint observations by the international researchers team from 45 institutions around the world, working together as one,” says Dr. Motoki Kino at Kogakuin University, the coordinator of the East Asian VLBI Network Active Galactic Nuclei Science Working Group. “Our observational data beautifully fitted to the simple sinusoidal curve bring us new advances in our understanding of black hole and jet system.”

In their paper published in Proceedings of the National Academy of Sciences, the group describes testing the myriapods under various scenarios to learn how they sense sunlight.

Venomous Chinese red-headed centipedes have long, black segmented bodies, yellow legs and a large, eyeless head with long antennae and a mouth capable of biting and injecting venom into prey, predators and humans that happen to step on them.

Prior research has shown that the centipede actively avoids sunlight, though it is not known if this is to avoid predators or prevent overheating. Prior research has also shown that in addition to having no eyes, the pencil-size bugs also have no photoreceptors, raising the question of how they know when the sun is shining on them.

To find out, the researchers conducted experiments that involved placing specimens in clear containers, some of which were covered with black tape. They then studied how the centipedes moved when exposed to differing amounts of light. They also used thermal cameras to record changes in body temperature during sunlight exposure. They found that the temperature of the antennae rose almost immediately when exposed to sunlight, and did so rapidly. Readings showed temperature increases of up to 9°C within seconds.

What If Cetrion Is A Human In Liu Kang's New Timeline

We all know that Raiden was reborn as human in Liu Kang's New Timeline.So, what if my favorite MK11 Cetrion was reborn as human instead of Elder God?

Cetrion is a newcomer Romanian foreigner university student who studies agriculture in Zhejiang University.She comes to Fengjian for studies related working & she met Raiden & Kung Lao while she appreciates the aesthetic of Fengjian village

Despite both of Raiden & Cetrion didn't know each others,they felt deja-vu as they used to meet each others but don't know where & how (Also, Kung Lao felt jealous)

A sweater made from new aerogel fiber tests warmer than one made from down

A team of chemical engineers and materials scientists at Zhejiang University in China has developed a new type of aerogel fiber that has proven to be warmer than down when woven into a sweater. In their paper published in the journal Science, the group describes the inspiration for their fibers, how they were made and how well they worked when tested in a cold environment. Zhizhi Sheng and Xuetong Zhang, with the Chinese Academy of Sciences, have published a Perspective piece in the same journal issue outlining the work done by the team on this new effort. Aerogels are types of gels where the liquid is replaced by air. They were invented in the 1930s and have been used for a variety of applications, including NASA space vehicles. Because of their positive thermal properties, materials scientists have been trying to make fibers using them that could be used to create warm textiles. Thus far, such attempts have mostly failed, however, due to a lack of moisture permeability and strength. In this new study, the research team in China has found a way to overcome both problems.

Mercury pollution of soil and water is a worldwide threat to public health. This new work suggests Metarhizium could provide an inexpensive and efficient way to protect crops grown in polluted areas and remediate mercury-laden waterways.

The study, which was conducted by UMD professor of entomology Raymond St. Leger and researchers in the laboratory of his former post-doctoral fellow, Weiguo Fang (now at Zhejiang University in Hangzhou, China),was published in Proceedings of the National Academy of Sciences (PNAS) on November 14, 2022.

"This project, led by Dr. Fang, found that Metarhizium stops plants from taking up mercury," said St. Leger. "Despite being planted in polluted soil, the plant grows normally and is edible. What's more, the fungus alone can quickly clear mercury from both fresh and saltwater."

Metarhizium is a nearly ubiquitous fungi, and previous work by the St. Leger laboratory had shown that it colonizes plant roots and protects them from herbivorous insects. Scientists have known that Metarhizium is often one of the only living things found in soils from toxic sites like mercury mines. But no one had previously determined how the fungus survived in mercury polluted soils, or if that had implications for the plants the fungus normally lives with.

St. Leger and other colleagues had previously sequenced the genome of Metarhizium, and Fangnoticed that it contains two genes that are very similar to genes present in a bacterium known to detoxify, or bioremediate, mercury.

For the current study, the researchers ran a variety of laboratory experiments and found that corn infected with Metarhizium grew just as well whether it was planted in clean soil or mercury-laden soil. What's more, no mercury was found in the plant tissues of corn grown in polluted soil.

The researchers then genetically modified the fungi, removing the two genes that were similar to those in mercury remediating bacteria. When they replicated their experiments, modified Metarhizium no longer protected corn plants from mercury-laden soil, and the corn died.

To verify that the genes were providing the detoxifying qualities, the researchers inserted them into another fungus that does not normally protect corn from mercury. The newly modified fungus performed like the Metarhizium, protecting the plants from mercury-laden soil.

Microbiological analyses revealed that the genes in question expressed enzymes that break down highly toxic organic forms of mercury into less toxic, inorganic mercury molecules. Lastly, the researchers genetically engineered Metarhizium to express more of the detoxifying genes and increase its production of the detoxifying enzymes.

In their final experiment, the researchers found they could clear mercury from both fresh and salt water in 48 hours by mixing in Metarhizium.
