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...

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...

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...

Many natural biological systems—such as biofilms, shells and skeletal tissues—create multifunctional and environmentally responsive multiscale assemblies of living and non-living components. Such living materials grow, self-repair, and adapt to the environment, possessing many living attributes that are unattainable for most artificial materials. Taking inspiration from nature and leveraging the p...

Recently, SPST Yang Xiaoyu’s group have achieved highly enantioselective synthesis of tertiary 2-amidoallylic alcohols, and their research was published in Angewandte Chemie International Edition with the title of “Kinetic Resolution of Tertiary 2-Alkoxycarboxamido-allylic Alcohols by Chiral Phosphoric Acid Catalyzed Intramolecular Transesterification.”Chiral alcohols are important building blo...

Gao Hanwen, a senior from Shandong Province, remembers visiting ShanghaiTech as a high school senior for Open Campus Day. In a one on one interview with professors, he asked them about scientific research. “All of the physics I knew was from the exam, was from the book and that's totally different from the research. So, in the one hand, I am very interested in physics. I was confused whe...

SPST scientists Professor Osamu Terasaki, Dr. Peter Oleynikov, Dr. Alvaro Mayoral and Dr. Ma Yanhang, have collaborated with Professor Kyung Byung Yoon to report a new layered vanadosilicate for removal of 90Sr from highly Na+-rich liquid nuclear waste. The paper was published in Energy & Environmental Science with the title of “Removal of 90Sr from highly Na+-rich liquid nuclear waste w...

Cancer is one of the biggest killers threatening human life and chemotherapy, which kills cancer cells with molecular drugs that are toxic to cells, is one of the main ways to treat cancer. For metastatic tumors, chemotherapy is the most effective method. However, chemotherapy drugs can also kill a large number of normal cells, causing severe toxic side effects and seriously damaging the physical ...

SPST Assistant Professor Liu Wei’s research group recently published an article titled “High-rate and large-capacity lithium metal anode enabled by volume conformal and self-healable composite polymer electrolyte” in Advanced Science.Lithium-metal batteries can provide a major leap in energy density for the applications of electric vehicles and smart grid, in light of growing demands for large-...

Recently, SPST Assistant Professor Zhang Yuebiao’s group reported a guest-dependent dynamic Covalent Organic Frameworks (COFs). In this Issue, they developed a facial and scalable method to produce homogeneous and highly-crystallinity COFs. For the first time, scientists discovered the crystal contraction and expansion of COFs based on gases and guest molecules. Their study, “Guest-Dependent Dyn...
