What Do Large Language Models Know About Materials?

open access: yesAdvanced 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 ...

A rapid and accurate direct measurement method of underground coal seam gas content based on dynamic diffusion theory

open access: yesInternational Journal of Mining Science and Technology, 2020
Coal seam gas content is frequently measured in quantity during underground coal mining operation and coalbed methane (CBM) exploration as a significant basic parameter.

Mathematical Modeling Of Horizontal Displacement Of Above-ground Gas Pipelines [PDF]

open access: yes, 2017
The modern geodetic equipment allows observations as soon as possible, providing high accuracy and productivity. Achieving high accuracy of measurement is impossible without taking into account external factors that create influence on an observation ...

Propagating elastic vibrations dominate thermal conduction in amorphous silicon [PDF]

open access: yes, 2017
Thermal atomic vibrations in amorphous solids can be distinguished by whether they propagate as elastic waves or do not propagate due to lack of atomic periodicity.

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

THE METHOD OF GAS-DYNAMIC CALCULATION OF NITROGEN CRYOSURGICAL APPARATUS

open access: yesHealth and Ecology Issues, 2015
The article considers the typical scheme of a nitrogen cryosurgical apparatus and describes the apparatus units such as the container with liquid nitrogen, capillaries to supply liquid and discard vapor phase of nitrogen, cryoprobe and operational tips. Methodologies for calculating hydraulic losses along the capillaries, local hydrodynamic resistances

Temperature dependence of the surface plasmon resonance in small electron gas fragments, self consistent field approximation

open access: yes, 2017
The temperature dependence of the surface plasmon resonance in small metal spheres is calculated using an electron gas model within the Random Phase Approximation. The calculation is mainly devoted to the study of spheres with diameters up to at least 10

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Dynamic structure function of a cold Fermi gas at unitarity [PDF]

open access: yes, 2014
We present a theoretical study of the dynamic structure function of a resonantly interacting two-component Fermi gas at zero temperature. Our approach is based on dynamic many-body theory able to describe excitations in strongly correlated Fermi systems.
