Real-time Collision-free Motion Planning for Next-generation Fiber Positioners in LAMOST
Multiobject fiber-fed spectrographs have thousands of fiber positioners packed on a focal plane with shared working space to move the fiber-ends in parallel, which maximizes observation time.

One‐Size‐Fits‐All: A Universal Binding Site for Single‐Layer Metal Cluster Self‐Assembly
A universal strategy enables the formation of single‐layer metal clusters (SLMC) across 21 elements by harnessing vacancy defects as binding sites. Crucially, synthesis occurs without reactive species, preventing site passivation and ensuring strong metal–surface bonding.

Ultra Low-Dispersion Spectroscopy with Gaia and Photographic Objective Prism Surveys
This paper discusses the ultra low-dispersion spectroscopy to be applied in the ESA Gaia space observatory and the ground-based objective-prism plate surveys. Although the dispersion in plate surveys is usually larger than in the Gaia BP/RP spectrometers,

Layer‐By‐Layer Approach to Improve the Capacitance of Conducting Polymer Films
This work describes the synthesis and characterization of a composite material based on poly(3,4‐ethylenedioxythiophene) (PEDOT) and poly(3,4‐ethylenedioxypyrrole) (PEDOP) deposited in a layer‐by‐layer approach. Due to the developed electroactive area coming from the presence of 3D nanostructures, PEDOT/PEDOP demonstrates superior areal capacitance ...
