Toward Decarbonization of the Titanium Industry via Hydrogen Plasma Smelting Reduction

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
Hydrogen plasma smelting reduction enables direct, zero‐carbon conversion of low‐grade ilmenite into steel‐grade iron and a titania‐rich precursor for pigment production. The single‐step process merges smelting and refining, sharply lowers silica content, and offers a breakthrough path for sustainable, high‐value extraction from abundant mineral sands.

Research Status and Development Trend of Macromolecular Structure and Model Construction of Different Coals

open access: yesAsia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT Coal is a natural macromolecular substance composed of complex organic molecules and a small amount of minerals. Its chemical composition and microstructure are highly complex and variable, and no unified definition exists. This inherent structural complexity underscores the theoretical significance of constructing accurate macromolecular ...

Recycling of Spent Cathode Carbon from Aluminum Electrolysis: Detoxification Approaches, Resource Utilization, and Environmental Perspectives

open access: yesChemElectroChem, Volume 13, Issue 1, January 2026.
This review outlines the recycling of spent cathode carbon from aluminum electrolysis. Detoxification strategies, including molten salt roasting and ultrasonic‐assisted leaching, are depicted as effective approaches for removing hazardous components. The recovered carbon is further directed toward resource utilization, such as in lithium‐ and carbon ...
