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...

Recently, a research group led by SPST Assistant Professor Liu Xuerong discovered delocalized dimer orbitals in an iridate material Ba5AlIr2O11 using resonant inelastic x-ray scattering (RIXS). They observed delocalized states resulting from the competition between the intersite hopping and strong spin-orbit coupling (SOC) of the electrons. Their study opens new directions to study the electr...

School of Physical Science and Technology Assistant Professor Liu Wei’s research group recently published a review tilted “Practical challenges and future perspectives of all-solid-state lithium metal batteries” in the internationally famous journal Chem.As energy storage devices, lithium-ion batteries have become fundamental building blocks of modern society for their high energy density, supe...

Recently, Assistant Professor Li Tao’s research group from School of Physical Science and Technology (SPST) reported a generalizable approach to construct MOF@polymer functional composites through surface-initiated atom transfer radical polymerization (SI-ATRP) in Chemical Science, the flagship journal of the Royal Society of Chemistry (RSC).Grafting polymers onto nanoparticle (NP) surfaces is a ...

Recently, Dr. Ling Shengjie's research group and their collaborators developed an environmentally friendly and scalable “partial dissolution and physical dispersion” strategy to exfoliate silk fibers into different mesostructures. On the basis of the advantages of these mesosilks in tunable sizes, sharp size distributions, high modulus, excellent redispersibility, as well as versatile proces...

The Zhong group in SPST's Materials and Physical Biology Division has recently made important progress in the development of living functional materials based on engineered Bacillus subtilis biofilms.
