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.
The improvement of high-repetition-rate Nd:YAG laser performances is still a long-standing challenge, although many novel architectures of the laser have been developed. High concentrations of Nd3+ crystals will bring serious thermal effects, possible concentration quenching at strong pump power. However, the high conversion efficiency is difficult to obtain for crystals with low concentrations of Nd3+.
