Advanced Science, EarlyView.Inspired by natural amino acid polymer‐melanin systems, this study strategically incorporated tellurocysteine to develop advanced radiation‐shielding materials. This approach transformed the primary interaction mechanism between melanin‐based materials and incident photons from Compton scattering to the photoelectric effect. Tellurocysteine‐polymerized

Helical Electron Beam Micro‐Bunching by High‐Order Modes in a Micro‐Plasma Waveguide
Advanced Science, EarlyView.ABSTRACT Electron acceleration by a high‐power Laguerre‐Gaussian pulse in a micro‐plasma waveguide is investigated. When the incident laser travels in the waveguide, electrons on the wall are extracted into the vacuum core and accelerated by the longitudinal field of the waveguide mode.

Astronomy Education in Universities of China [PDF]
Transactions of the International Astronomical Union, 2001 AbstractIn China, more than twenty universities have astronomy education and research work. In four key universities, a complete series of educational programs of undergraduate, master’s, doctoral and postdoctoral levels has been formed. After four-year study at the undergraduate stage, students can be enrolled in master degree specialties. Three years

Imaging Electric Polarization Switching in Multilayer Graphene
Advanced Science, EarlyView.Domain wall sliding‐induced electric polarization switching is directly observed for the first time in multilayer graphene, enabled by a novel optical readout method. The polarization switching is realized upon application of global and local electric fields, and mechanical forces between neighboring polar domains of opposite out‐of‐plane polarizations
