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.

Microwave limb sounder [PDF]

open access: yes, 1981
Trace gases in the upper atmosphere can be measured by comparing spectral noise content of limb soundings with the spectral noise content of cold space. An offset Cassegrain antenna system and tiltable input mirror alternately look out at the limb and up

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.

Review of conceptual and empirical approaches to characterize infiltration

open access: yesVadose Zone Journal, Volume 24, Issue 1, January/February 2025.
Abstract Infiltration regulates the movement and storage of water at the soil–atmosphere interface and is, therefore, a key component of many related physical and biogeochemical processes. Numerous studies have examined infiltration over the past two centuries.
