Summary: In recent years, practical engineering applications such as fiber-optic gyroscope, wavelength division multiplexing, and optical coherence tomography have put forward higher requirements on light sources due to the rapid development of military, optical communication, biological imaging, and other fields. Amplified spontaneous emission (ASE) light source has become an excellent candidate due to its advantages such as suitable bandwidth, low coherence, and high power. This review analyzes the principle of the ASE effect, summarizes the optical gain properties of various gain materials and different structural types of electrically pumped ASE devices, and prospects the development of new ASE light-emitting devices integrated with high-gain materials and low-cost structures.

Summary: The combination of acoustically levitated droplets, mid-IR laser evaporation, and subsequent post-ionization by secondary electrospray ionization was used to monitor the enzymatic digestion of various proteins. Acoustically levitated droplets provide a wall-free model reactor for compartmentalized microfluidic trypsin digestions. Time-resolved interrogation of the droplets provides real-time information on the reaction progress and insights into reaction kinetics. Importantly, the experimental setup can be used for the real-time investigation of chemical reactions and uses only a fraction of the typically applied amounts of solvent, analyte, and trypsin, making it a green analytical chemistry alternative to batch reactions.

Summary: In this study, CsPbBr3 perovskite light-emitting diodes (PeLEDs) were successfully fabricated on n-Si substrates by tailoring the interfaces of perovskite layers. The use of ZnO nanofilms modified with ethoxylated polyethyleneimine (PEIE) as electron transport layers and polyvinylcarbazole (PVK) layers as hole transport layers resulted in high brightness and good stability of green electroluminescence. This approach of making perovskite-based LEDs on silicon substrates holds great potential for integration with microelectronics and for the commercialization of low-cost perovskite materials and printed electronic devices.
