What Do Large Language Models Know About Materials?
Advanced Engineering Materials, EarlyView.If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Can Ti‐Based MXenes Serve as Solid Lubricants for Brake Applications? A Tribological Study
Advanced Engineering Materials, EarlyView.This study explores the first implementation of Ti‐based MXenes materials in brake pad friction composite material. The resulting composite material exhibits a 48% reduction in the wear rate; alongside significant improvements are observed for thermal and mechanical properties.

Advanced Engineering Materials, EarlyView.This study proposes a new methodology for producing metal matrix nanocomposites in the solid state. The process involves the plasma‐assisted thermochemical treatment of metallic alloy powders. As a proof‐of‐concept, TiN nanoparticles are synthesized directly on the surface of FeTi intermetallic powder particles, enabling the development of the ...

Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Direct Demodulation of Optical BPSK/QPSK Signals without Digital Signal Processing [PDF]
Radioengineering, 2018 We experimentally demonstrate the coherent detection of 5-Gbd/s BPSK/QPSK signal by direct phase compensation of the phase noise without using a sophisticated digital signal processing algorithm.
