CMs (nonspherical clusters of a small number of particles) have potential applications in coatings, material self-assembly, biomedical diagnostics. The sphere has the smallest surface area under a certain volume, that is, the total Gibbs free energy of the surface is the lowest. Therefore, most nanoparticles exhibit spherical shape, leading to difficult preparation of non-spherical CMs.
Recently, a collaborated team led by Professor SU Fuhai from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), successfully Identified the ultrafast dynamics in monolayer MoS2/ReSe2 heterostructures.
Although many diseases have no obvious symptoms in the early diagnosis, it’s proved that human body would defend itself through the immune system in the early stage of disease. Corresponding signals, such as sweat, urine, tears, blood, exhaled breath, are usually sent out for early warning.
Human telomeric DNA consists of a tandem array of the G-rich repeat unit d(GGGTTA). A four-stranded helical structure adopted by G-rich sequences was named G-quadruplex (GQ) under physiological condition. The final 3'-terminal residue of the telomeric DNA G-overhang is inherently less precise.
China's 12th Arctic scientific expedition, organized by the Ministry of Natural Resources, returned to Shanghai on Sept. 28 on board XueLong 2. The team set sail from Shanghai on July 12, covering a total distance of 14,000 sea miles in 79 days.
