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 ...

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

Advanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Single‐Step Synthesis of In‐plane 1T'‐2H Heterophase MoTe2 for Low‐Resistance Contacts

Advanced Functional Materials, EarlyView.
A single‐step CVD method is developed to synthesize seamless in‐plane 1T'‐2H MoTe2 heterophase junctions with precise phase control and uniform large‐area coverage. The resulting transistors, incorporating 1T' MoTe2 contacts and 2H MoTe2 channels, exhibit ultralow contact resistance, offering a scalable solution to the long‐standing challenge of ...

The microbiomic signature of hemorrhoids and comparison with associated microbiomes

Frontiers in Microbiology
Hemorrhoids are a common ailment that can cause significant disruptions to one’s daily life. While some researchers have speculated about a potential link between hemorrhoid development and gut microbes, there is currently insufficient evidence to ...

Ultrahigh Strength with Suppressed Flow Instability at Liquid Helium Temperature via Coherent Nanoprecipitation in a Medium‐Entropy Alloy

Advanced Functional Materials, EarlyView.
It is demonstrated that severe lattice distortion and coherent nanoprecipitates overcome the strength–ductility dilemma and mitigate discontinuous plastic flow (DPF) at 4.2 K. Such microstructural design enhances both thermal and athermal stress components, leading to exceptional mechanical performance.

Features of treatment of haemorrhoids in overweight patients

Амбулаторная хирургия, 2023
Hemorrhoidal disease is one of the most common proctological diseases in the population, covering, according to a number of authors, from 4 to 86% of the population over the age of 40 years. In addition, the problem of metabolic syndrome and accompanying

Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation

Advanced Functional Materials, EarlyView.
The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.
