  • Enhancement of magnonic frequency combs by exceptional points
    Optical frequency comb, composed of discrete spectral lines, derives the name from its presenting a uniform and comb-like distribution of signals in the frequency domain. Frequency dimension has its significance as emphasized by Nobel laureate Arthur Schawlow’s quote, “Never measure anything but frequency”. The optical frequency comb significantly enhances the precision of freque...

  • Highly efficient tin-based tandem solar cells based on “surface freezing” strategy
    Perovskite is currently the most promising new type of solar cell material. Perovskite-based ultra-efficient solar cells have been rated as one of the “Top 10 Breakthrough Technologies of 2024” by MIT Technology Review. The commonly used lead perovskite solar cells have achieved high photoelectric conversion efficiency, but they still have shortcomings in terms of environmental friendliness and ...

  • Beyond nanolithography: a 3D printing paradigm shift
    **This article is provided by Prof. Feng Jicheng, and is originally published on the Materials Community of Springer Nature on August 16High-performance electronics requires billions of transistors, but their downsizing and interconnections, and materializations impose technological limits. Three-dimensional (3D) printing at nanoscale can probably provide a solution. Convergence between ...

  • A natural sweetener serves as the new carbon source for Escherichia coli growth
    Erythritol is a C4 sugar alcohol that naturally exists in some vegetables, fruits, mushrooms, and fermented foods. Because of its stable physical and chemical properties, low price, high biological safety, and the fact that it cannot be metabolized by the human body, erythritol is widely used in the food industry as a natural sugar substitute (such as in sugar-free sodas). Due to the lack of eryth...

  • Advances in high performance circularly polarized light detection by ShanghaiTech
    The rosy clouds of dawn, the sunset glow, the hazy moonlight and the rainbow are all forms of light found in nature.From an optical point of view, natural light, which does not directly show polarization, is isotropic. When natural light passes through a linear polarizer, it becomes linearly polarized. Through a quarter-wave plate, the linearly polarized light then becomes circularly polarized. Ci...

  • Progress made in the research of pressure-induced superconductivity in thallium-based topological materials
    The discovery of topological states and topological phase transitions has reshaped our understanding of physics and materials over the past few years. The topological transition from a normal insulator to a topological insulator (TI) can be realized by chemical or mechanical pressure. The topological transition was first predicted and demonstrated in Tl-based chalcogenides TlBi(S1−xSex)2 by i...

  • New synthetic strategy for phosphorus-based polycyclic aromatic molecules
    Organic π-conjugated molecules (OCMs) have become promising candidates in the fields of organic catalysts, bio-imaging/sensing, and organic optoelectronics. Recently, introducing main-group elements (such as B, N, S, Si, P, etc.) into molecular backbones has become a powerful strategy for fine-tuning photo-physics, redox characteristics, molecular organizations, and optoelectronic functionalities...

  • Novel electronic structures of magic-angle twisted trilayer graphene studied by nano-ARPES
    Rich and tunable physical properties could emerge from the moiré superlattice constructed from two-dimensional multilayers. The magic-angle twisted bilayer graphene (MATBG) is one of the most distinguished examples, which exhibits unconventional superconductivity, correlated physics, ferromagnetism, and nontrivial topology far beyond monolayer graphene. Recently, magic-angle twisted trilayer grap...

  • Several promising progress made to move forward to solid-state lithium-metal batteries
    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...
