Research progress on methane combustion catalysts

能源环境保护, 2023
Methane as the main component of natural gas, has been widely used in power plants, natural gas automobiles, and the synthesis of numerous compounds. However, the leakage and emission of methane can induce severe environmental issues due to its strong ...

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

A new large‐volume equilibration method for high‐precision measurements of dissolved noble gas stable isotopes

, 2023
Rationale Noble gases are widely used as physically based climate proxies, notably in dissolved water samples as tracers of past recharge temperature in groundwater and air–sea gas exchange processes in seawater. Recent advances in measuring large-volume

Characteristics of noble gases in the large Gaoshiti-Moxi gas field in Sichuan Basin, SW China

Petroleum Exploration and Development, 2014
Taking the large Gaoshiti-Moxi gas field of Sichuan Basin as an example, the total composition contents and isotopes of noble gases in the natural gases from the Sinian Dengying Formation and Cambrian Longwangmiao Formation are analyzed, and then their ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Position resolution limits in pure noble gaseous detectors for X-ray energies from 1 to 60 keV

Physics Letters B, 2015
The calculated position resolutions for X-ray photons (1–60 keV) in pure noble gases at atmospheric pressure are presented. In this work we show the influence of the atomic shells and the detector dimensions on the intrinsic position resolution of the ...

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Plasma control of the emission spectrum of mercury-noble-gas discharges [PDF]

, 2000
For certain applications, it would be convenient to be able to change the colour temperature and the luminous flux of artificial lighting independently. A promising candidate for this purpose is the fluorescent lamp.

Bulk Viscosity of Dilute Gases and Their Mixtures

Fluids, 2023
In this work, we use the Green–Kubo method to study the bulk viscosity of various dilute gases and their mixtures. First, we study the effects of the atomic mass on the bulk viscosity of dilute diatomic gas by estimating the bulk viscosity of four ...
