Upcycling Printed Circuit Board E‐Waste to High‐Strength, Multifunctional, and Reprocessable Sulfur Composites via Thiocracking

ChemSusChem, Volume 19, Issue 7, 14 April 2026.
Thiocracking, the one‐pot reaction of elemental sulfur with printed circuit board waste, converts unrecyclable laminates into high‐sulfur composites. The most practical material prepared herein combines cement‐like strength with 100% strength retention after 10 melt–recast cycles, low thermal conductivity (0.37 W m−1 K−1), and antimicrobial efficacy ...

A Level Set Approach for a Premixed Flame Based on a New Concept of Flame Speed

Journal of Thermal Science and Technology, 2011
In this paper we propose a new level set approach to describe not only a flame's surface but also to the flame's spatial distribution. First, we derived the mathematical formulation for a one-dimensional laminar premixed flame, where the steady

Applications of Hydrogenous Species for Initiation of Carbon Monoxide/Air Premixed Flame

Energies
Carbon monoxide (CO) is classified as a simple fuel that contains one carbon and one oxygen atom. The oxidation of CO with an oxidizer is relatively unusual, with the oxidation of CO having a slow reaction time.

Low‐Dimensional MOF Nanoarchitectonics: Progress in MOF‐2D Material Hybrid Architectures for Energy Conversion and Storage

Advanced Materials, Volume 38, Issue 19, 1 April 2026.
This review highlights the integration of metal‐organic frameworks (MOFs) and two‐dimensional (2D) materials through dimensional interface engineering. By addressing intrinsic limitations like poor conductivity and agglomeration, these hybrid architectures optimize interfacial charge and mass transport.

Theoretical Model of Transient Regression of Thermoplastic Materials During Flame Spread: Vaporization; Permanent Mass Loss; Surface Shape

Fire and Materials, Volume 50, Issue 3, Page 227-240, April 2026.
ABSTRACT This article examines a transient, one‐dimensional model of surface regression during opposed flow flame spread over finite thickness, non‐charring thermoplastics. Gas to solid conductive transfer from the flame drives sample heating. The solid degrades into volatile fuel molecules in two stages: (1) the pre‐vaporization heat‐up stage and (2 ...
