Coronoids are polycyclic aromatic compounds formed by annulated benzene rings that enclose a cavity in the center. They can be regarded as nanoporous graphene molecules whose electronic properties are critically dependent on the size and topology of their outer and inner peri...

A critical factor in next-generation energy storage systems is that all-solid-state lithium-metal batteries are expected to provide better safety and higher energy density than traditional lithium batteries which contain liquid materials inside which can be unsafe, flammable and hard to recycle. The significant difference in all-solid-state lithium-metal batteries is the solid electrolytes which r...

In natural silk spinning process, the molecular assembly synergistically realizes the complex and ordered mesoscopic hierarchies. Inspired by this, SPST Ling Shengjie's group cooperated with Yao Yuan's group from ZJU-Hangzhou Global Scientific and Technological Innovation Center, to combine the “molecular-supramolecular assembly” and “phase transition-induced mechanical training” ...

On May 7, the results of the 2021 Young Chemistry Award of the Chinese Chemical Society were announced. SPST Associate Professor Ji Quanjiang won this award for his developing a novel gene editing system that is easy to use in disease treatment. Prof. Ji Quanjiang is mainly engaged in the research of Cas nuclease mining, mechanism, and molecular evolution, and is committed to developing ...

Photoswitches are a class of molecules that can change their structural geometry after light exposure, and have wide applications in light-responsive materials, ion transport, and biomedicine. The speed at which the photoswitch changes structural geometry (i.e. thermal relaxation rate) is an important factor that determines its application scenarios, so the regulation of this performance is of gre...

Compared with traditional solar cells, perovskite solar cells have the characteristics of high efficiency and low cost, and are considered to be the most promising next-generation solar cells. However, the widely used lead perovskite material has a wide band gap, which limits its theoretical maximum efficiency. In recent years, tandem solar cells based on the superposition of wide-bandgap and narr...

The quantum anomalous Hall (QAH) effect, an important research direction in the field of condensed matter physics, is generated by the spontaneous magnetization of the material itself without relying on a strong magnetic field. When a perpendicular magnetic moment is introduced into the host topological insulators, the broken time-reversal symmetry lifts the spin degeneracy and gives rise to ...

Recently, Clarivate Analytics released the list of Highly Cited Researchers for the year of 2021. A total of 6,602 scientists from more than 70 countries have been selected. The highly cited papers of the selected scientists on the list have a cited frequency in the top 1% of their disciplines, reflecting their significant academic influence among their peers. Assistant Professor Liu Wei of SPST w...

The real-world deployment of the organic-inorganic hybrid perovskite solar cells is hindered by their instability to external stimuli such as heat and moisture. The low-dimensional perovskite (LDP), consisting of layered perovskite slabs separated by large organic spacers, is a promising candidate to address the stability issues while maintaining the remarkable optoelectronic properties. Much effo...

On June 1, 2020, ShanghaiTech University and the Publications Division of the American Chemical Society (ACS) announced their first publishing collaboration to create a new journal for the worldwide research community - Accounts of Materials Research. This important journal launch marks the first global publishing partnership for the two organizations, supporting both their missions and their...

Recently, Ning Zhijun's research group from School of Physical Science and Technology has reported a new type of infrared up-conversion photodetector based on colloidal quantum dots (CQDs) with low-cost and high-efficiency (Figure 1). The results was published in Nature Electronics with the title "Solution-processed up-conversion photodetectors based on quantum dots". ...

Recently, Professor Yu Yi's research group from School of Physical Science and Technology, in collaboration with the research team of Purdue University, have made important progress in the research of novel semiconductor heterostructures. For the first time, two-dimensional halide perovskite lateral epitaxial heterostructures have been successfully synthesized and characterized. On April 29, 2...

Research teams led by SPST Assistant Professor Ji Quanjiang and Fudan University Professor Gan Jianhua recently used structural biology, biochemical, and cell-based genome editing experiments to reveal the mechanisms of the PAM expansion and fidelity enhancement of a new evolved Cas9 nuclease xCas9. Their work, “Molecular basis for the PAM expansion and fidelity enhancement of an evolved Cas9 nuc...

Liquid sorbents, such as water, polyethylene glycol (PEG), and organic amine solutions, are widely used in many industrial processes for acid gases removal. This process is called wet scrubbing. However, most liquid sorbents have high vapor pressure and are sometimes even corrosive to the equipment. These undesirable features greatly increase the cost of separation and complicate facility design. ...
