Toward decarbonization of the titanium industry via hydrogen plasma smelting reduction

Advanced Science, EarlyView.
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.

Transition‐Metal‐Free Zeolite Composites for Tandem Catalytic Conversion of Methane to Light Olefins

Advanced Science, EarlyView.
Light olefins can be produced from methane using a cascade catalytic system that combines transition‐metal‐free (FER zeolite with an acidic zeolite, such as SAPO‐34, under relatively mild conditions. In this tandem process, methane is first oxidized to methanol over the FER zeolite and then converted to olefins via the MTO reaction on the acidic ...

Dual Regulation on Structure‐Interface Enables Coal‐Tar‐Pitch‐Based Hard Carbon Anodes with High Rate and Storage Performance for Sodium Ion Batteries

Advanced Science, EarlyView.
This study utilizes coal tar pitch (waste product generated during the coal conversion process) as a raw material. The core concept of synergistic “structure‐interface” regulation, an innovative system from molecular design to microcrystalline optimization, pore reconstruction, and interface regulation is proposed.

Trifunctional DOPO‐Engineered Polypropylene Separator With Li⁺‐Concentrating Interfaces for High‐Safety Lithium‐Ion Batteries Under Extreme Conditions

Advanced Science, EarlyView.
A DOPO‐based cross‐linked polymer creates a multifunctional separator for lithium‐ion batteries. It concurrently addresses safety (flame retardancy, thermal stability) and performance (enhanced Li+ transport, capacity retention), pioneering a novel approach to high‐performance battery design. Abstract This study develops a cross‐linked polymer modified
