Fullerene chemistry is a field of organic chemistry devoted to the chemical properties of fullerenes. Research in this field is driven by the need to functionalize fullerenes and tune their properties. For example, fullerene is notoriously insoluble and adding a suitable group can enhance solubility. By adding a polymerizable group, a fullerene polymer can be obtained. Functionalized fullerenes are divided into two classes: exohedral fullerenes with substituents outside the cage and endohedral fullerenes with trapped molecules inside the cage.

Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China, as well as inland waters of the larger part of central Asia. They can be distinguished from other genera of Nemacheilidae by marked sexual dimorphism, including the development of nuptial tubercles on breeding males. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera, but as Wikipedia follows Fishbase for fish species all but Hedinichthys have been treated as subgenera in Wikipedia, although Kottelat in his revision of the loaches did recognise them as valid. FishBase, however, includes these in Triplophysa without specifying subgenera and treats the names given by Kottelat as synonyms.

Xiaoliang Sunney Xie is a Chinese biophysicist well known for his contributions to the fields of single-molecule biophysical chemistry, coherent Raman Imaging and single-molecule genomics. In 2023, Xie renounced his U.S. citizenship in order to reclaim his Chinese citizenship.
Family with sequence similarity 20, member C also known as FAM20C or DMP4 is a protein which in humans is encoded by the FAM20C gene. Fam20C, a Golgi localized protein kinase, is a serine kinase that phosphorylates both casein and other highly acidic proteins and members of the small integrin-binding ligand, the N-linked glycoproteins (SIBLING) family at the target motif SerXGlu.
The Tiaojishan Formation is a geological formation in Hebei and Liaoning, People's Republic of China, dating to the middle-late Jurassic period. It is known for its exceptionally preserved fossils, including those of plants, insects and vertebrates. It is made up mainly of pyroclastic rock interspersed with basic volcanic and sedimentary rocks. Previously, the Tiaojishan Formation was grouped together with the underlying Haifanggou Formation as a single "Lanqi Formation." The Tiaojishan Formation forms a key part of the Yanliao Biota assemblage, alongside the Haifanggou Formation.
The Yixian Formation is a geological formation in Jinzhou, Liaoning, People's Republic of China, that spans about 1.6 million years during the early Cretaceous period. It is known for its fossils, listed below.

Li Jiayang is a Chinese agronomist and geneticist. He is Vice Minister of Agriculture in China and President of the Chinese Academy of Agricultural Sciences (CAAS). He is also Professor and Principal investigator at the Institute of Genetics and Development at the Chinese Academy of Sciences (CAS).
Sinotaia quadrata is a species of a freshwater snail with a gill and an operculum, an aquatic gastropod mollusk in the family Viviparidae. It is widely distributed and common species in China and in northern Vietnam inhabiting various shallow freshwater habitats, where it can reach high densities. It is a keystone species in its habitat and can significantly affect water quality and phytoplankton communities. It is commonly used in Chinese cuisine.
CKLF-like MARVEL transmembrane domain-containing protein 3, also termed chemokine-like factor superfamily 3, is a member of the CKLF-like MARVEL transmembrane domain-containing family of proteins. In humans, CMTM2 protein is encoded by the CMTM3 gene located in band 22.1 on the long arm of chromosome 16. This protein is expressed in a wide range of tissues, including fetal tissues. It is highly expressed in the male reproductive system, particularly testicular tissues and may play a role in the development of this tissue. It is also highly expressed in the immune system including circulating blood cells, i.e. B lymphocytes, CD4+ T lymphocytes, and monocytes. However, CMTM3 protein is weakly expressed or unexpressed in the malignant tissues of several types of cancers. In many but not all of theses cancers, this decreased or lack of expression appears due to methylation of the GpC islands in the promoter region, and thereby the silencing, of the CMTM3 gene.
Metapristone is the major metabolite of mifepristone and a selective progesterone receptor modulator (SPRM) which itself was never marketed. It is formed from mifepristone in the liver by the enzyme CYP3A4 via monodemethylation, and circulates at concentrations higher than those of mifepristone. The metabolite retains partial but considerable affinity for the progesterone receptor (PR) and the glucocorticoid receptor (GR). On the basis of actions that are apparently independent of its hormonal activity, metapristone is being researched as a potential cancer metastatic chemopreventive agent.

In chemistry, a pentazolate is a compound that contains a cyclo-N5− ion, the anion of pentazole. In 2017, researchers prepared the first salt (N5)6(H3O)3(NH4)4Cl containing pentazolate anion starting a substituted phenylpentazole, m-CPBA and iron(II) glycinate. A series of metal and nonmetal pentazolates were subsequently synthesized according to their work.
The Sinopharm WIBP COVID-19 vaccine, also known as WIBP-CorV, is one of two inactivated virus COVID-19 vaccines developed by Sinopharm. Peer-reviewed results show that the vaccine is 72.8% effective against symptomatic cases and 100% against severe cases. The other inactivated virus COVID-19 vaccine developed by Sinopharm is the BIBP vaccine (BBIBP-CorV) which is comparably more successful. 1 billion doses are expected to be produced per year.
