Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction

steel research international, EarlyView.
Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in

The Combined Effect of Gas Phase and Condensed Phase Mechanisms in Flame Retardancy of Polybutylene Succinate

Journal of Vinyl and Additive Technology, EarlyView.
A combination of DOPO and APP flame‐retardants results in a V‐0 UL 94 rating. ABSTRACT In this study, we addressed the challenge of eliminating, during combustion, the flaming dripping behavior of polybutylene succinate flame retarded with ammonium polyphosphate, a key barrier to achieving a V‐0 rating in the UL 94 flammability test without excessive ...

Analytical study of initial flame kernel in laser ignition

Journal of Thermal Science and Technology
The formation process of an initial flame kernel in laser ignition was analytically examined for understanding its experimentally-observed hugeness. First, we evaluated the thermodynamic state of the laser-heated plasma by examining the laser-absorption ...

A Low‐Cost Multifunctional PDMS Sponge Based on Boron Compounds and Waste‐Derived Candle Soot for Flame‐Retardancy, Oil–Water Separation, and Self‐Cleaning

Journal of Vinyl and Additive Technology, EarlyView.
A multifunctional PDMS sponge modified with boron compounds and candle soot exhibits superhydrophobicity, flame retardancy, and efficient oil adsorption. The porous structure enables rapid oil uptake, stable self‐cleaning behavior, and improved fire resistance, highlighting its potential for environmental remediation and safe oil–water separation ...

HiPER: The European path to laser energy

EPJ Web of Conferences, 2013
While for decades, energy production relying on laser inertial fusion has been a strong motivation for the development in Europe of a few high-energy laser facilities and dedicated scientific programs, the HiPER initiative launched in 2004 fostered an ...
