Improving the Cleanness of Low-Carbon Tube Steel Under Steel Plant Conditions

open access: yesAdvances in Materials Science and Engineering
Reducing the number of nonmetallic inclusions in high-quality steel rolled products is of great importance for all steel plants. One of the ways to decrease the size and quantity of alumina and silicate nonmetallic inclusions could be suppressing their ...

Nonmetallic inclusion removal of Si-Mn deoxidized steel by nitrogen absorption and release method

open access: yes工程科学学报, 2018
The micro nonmetallic inclusion and oxygen content in steel significantly affect its performance, and removing the inclusion involves a difficult process. A nitrogen absorption and release method has been developed with which nonmetallic inclusions and T[

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

open access: yesAdvanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Establishing a Model Precursor System: Over a Decade of Research on Carbon Dots from the Citric Acid‐Urea System

open access: yesAdvanced Functional Materials, EarlyView.
The citric acid/urea (CA‐Urea) precursor system offers a versatile, scalable route to carbon dots with tunable luminescence and multifunctionality. Mechanistic insights into precursor chemistry and reaction parameters have enabled doping, surface modification, and hybridization strategies, yielding CDs for luminescent devices, sensing, catalysis ...

Influence of nonmetallic inclusions on microbreaks formation in wheel steel and railway wheels [PDF]

open access: yesTransport Problems, 2008
It is well known that formation of defects of many types during railway wheels service somehow or other is connected to nonmetallic inclusions in wheel steel. Microbreakes connected with nonmetallic inclusions have different origin.

Effect of crowning radius on rolling contact fatigue strength for traction drive elements [PDF]

open access: yes, 2014
A simulation of the rolling contact fatigue strength of a traction drive element was developed. This simulation accounts for both the distribution of sizes of inclusions in the element material and the influence of traction forces at the element surface.
