Pushing the Frontiers: Artificial Intelligence (AI)‐Guided Programmable Concepts in Binary Self‐Assembly of Colloidal Nanoparticles

open access: yesAdvanced Science, Volume 12, Issue 28, July 24, 2025.
Colloidal nanoparticles self‐assembly advances towards intelligent, customized assembly through precise control of binary co‐assemblies. This review explores the evolution from monolithic to binary assemblies, highlighting how the AI‐guided programmable assembly approach has the potential to shift from passive assembly to active intelligent design.

Oued Chebeika 002: A new CI1 meteorite linked to outer solar system bodies

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 7, Page 1441-1479, July 2025.
Abstract CI1 chondrites are rare meteorites with high scientific value. In fact, they are the most chemically primitive meteorites and show evidence of intense parent‐body aqueous alteration. They also share strong similarities with samples from Ryugu and Bennu asteroids returned by the JAXA Hayabusa2 and NASA's OSIRIS‐REx missions.

Thermo‐Mechanical Degradation Kinetics of a High‐Density Poly(Ethylene) Using a Closed‐Cavity Rheometer

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 17, May 5, 2025.
A time and material saving method to investigate multiple processing of polyolefins is developed. A commercial rheometer is used to emulate a thermo‐mechanical treatment of the polymer during processing. A kinetic model is suggested to predict the change of the molecular weight as a function of time, temperature and in‐phase shear stress.

Ancient and historical cooking pots and food: an eternal communion. A topical review

open access: yesArchaeometry, Volume 67, Issue 1, Page 219-234, February 2025.
Abstract This contribution provides a topical view at and review of traditional clay‐based utilitarian cooking pots that were used for millennia to prepare, serve, display, and distribute foodstuff. Key mechanical and thermal properties of ceramic cooking vessels will be discussed and strategies of property optimization outlined.

Intelligent vehicle scheduling in open-pit mines based on 5G antenna and improved Dijkstra algorithm

open access: yesGong-kuang zidonghua
Complex terrains such as deep pits and high slopes in open-pit mines cause physical signal blockage and multipath fading. Furthermore, existing path-planning algorithms tend to result in unstable vehicle trajectories or congestion due to local optima ...
