Covalent organic frameworks are 2D or 3D porous crystals built by organic molecules through covalent bonds. Due to the framework stability and accurate control at molecular-level, this type of material shows potential applications in gas adsorption/separation, energy storage and conversion, drug delivery and so on. Recently, a collaborative work by SPST Assistant Professors Zhang Yuebiao and Ma Ya...

Each summer, a band of foreign students arrive on ShanghaiTech’s campus for six to eight weeks of research. For science major students, there are fewer opportunities for study abroad than other disciplines, and yet they are no less eager to experience another culture. The summer research program allows students from partner institutions the chance to experience Chinese culture while gaining resea...

Organic-inorganic hybrid halide perovskites are emerging as a promising material in light-emitting diodes (LEDs) for their remarkable optoelectronic properties, including narrow full width half maximum (FWHM), high luminescence quantum yield (PLQY), and solution processability. The external quantum efficiency (EQE) of perovskites LEDs has exceeded 20% in just 5 years. However, the poor stability s...

Recently, an SPST team of researchers led by Professor Chen Yulin successfully demonstrated in-situ manipulation of surface Fermi arcs (SFAs) – the signature electronic structures of Weyl semimetal – and realized their topological Lifshitz transition via surface decoration in ultra-high vacuum environment. The study, “Topological Lifshitz transitions and Fermi arc manipulation in Weyl semimetal N...

The 2nd International Conference on Vibration and Energy Harvesting Applications (VEH 2019) was held in the School of Information Science and Technology (SIST) from July 13th to 15th, attracting 150 scholars, researchers, and students from universities and research institutions around the world such as Imperial College London, University of Paris-Sud, Virginia Polytechnic Institute, Stevens Instit...

Recently, SPST Dr. Liu Wei’s group reported new progress in fabricating high-performance electrode for lithium-ion batteries in a paper entitled “High-Performance, Low-Cost, and Dense-Structure Electrodes with High Mass Loading for Lithium-Ion Batteries” in the journal Advanced Functional Materials. The lithium-ion battery has now been widely used in portable electronics. However, their en...

In the 19th International Zeolite Conference in Perth, Australia, the Donald W. Breck award was given to CħEM Director Professor Osamu Terasaki, Assistant Professor Ma Yanhang and their collaborators for the discovery of enantiomerically enriched STW zeolite.Donald W. Breck of the Union Carbide Corporation was a major figure in the early development of synthetic molecular sieves and one of the fou...

Understanding adsorption behavior in porous crystals is critical for their rational design and performance optimization at the molecular level. A collaborative team led by ShanghaiTech University Professor Osamu Terasaki has developed “gas adsorption crystallography” for tracing adsorbates in each pore of porous crystals even with intricate pore structures.As a collective phenomenon, adsorption ...

SPST Dr. Mi Qixi’s group reported their new progress in lead-free perovskite materials in a paper entitled “Band Alignment Boosts Charge–Carrier Collection in Sn-Based Perovskite over Pb Counterparts,” published in the Journal of Physical Chemistry Letters and was highlighted as a cover illustration.The group previously discovered that CsSnBr3 (cesium tin bromide) has excellent semico...

SIST Assistant Professor Chen Baile’s group demonstrated high-speed photodetector at 2-micron waveband. This photodetector, operating at 2-micron wavelength band, has a high 3dB bandwidth up to 25 GHz, and achieves a clear eye pattern at 30 Gb/s. It is reportedly the fastest photodetector operating at 2-micron. Their achievement was recently published in Optica in an article entitled “High-...

Recently, SPST Lin Bolin’s group developed heterovalent doped 2D Ruddlesden-Popper organic lead halide perovskites and their work was published in Journal of Medicinal Chemistry in an article titled “Bi3+ doped 2D Ruddlesden-Popper Organic Lead Halide Perovskites.”Two-dimensional Ruddlesdan-Popper organic lead halide perovskites (2D RPPs) are a kind of semiconducting material that hav...

ASSIST 2019, ShanghaiTech’s annual information science and technology symposium , was held from June 30th to July 2nd.
