Vehicle Fires: Significant Fire Hazard in Transportation Infrastructure

open access: yesFire and Materials, Volume 50, Issue 8, Page 927-940, December 2026.
ABSTRACT Vehicle flammability poses a critical threat to transportation infrastructure, with recent fires in depots, tunnels, and car parks highlighting systemic vulnerabilities. These incidents often result in the total loss of vehicles and buildings, revealing the inadequacy of current fire safety standards for vehicle materials.

Synthesis of functionalized polyolefins in a new continuous bench‐scale reactor apparatus

open access: yesAIChE Journal, Volume 72, Issue 9, September 2026.
Abstract In‐reactor functionalized polyolefins (FPOs), produced by molecular catalysts, are a new class of polymer materials with applications ranging from high performance adhesives to bitumen compatibilization. In this work, we disclose a procedure for the synthesis of FPOs in a new Continuous Bench‐scale Reactor Apparatus (COBRA).

Rasterized Infrared Curing of Aromatic Polyester Vitrimers for Additive Manufacturing and Thin Films Enabled by Dynamic Bond Exchange

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 9, September 2026.
A novel advancing‐front rasterized infrared curing method was developed for an Aromatic Thermosetting Copolyester (ATSP) vitrimer, employing feedback‐controlled thermal pulses to drive the progressive evolution of a dynamic covalent network. Thermogravimetric analyses established a predictable relationship between tunable cure profiles and cure ...

Stiffness of cold-recycled mixtures under variable deformation conditions in the IT-CY test

open access: yesCase Studies in Construction Materials, 2023
Stiffness modulus belongs to the most important properties describing the cold-recycled mixtures (CRM) in terms of their usability in road pavement structures. Previous research proved that this property is strongly dependent on the scheme and conditions

Bitumen Foaming Optimisation Process on the Basis of Rheological Properties

open access: yesMaterials, 2018
This article discusses the results of bitumen foam properties optimisation with respect to three factors: air pressure, bitumen temperature and amount of water. The test materials were unmodified bitumen 50/70 and bitumen 50/70 modified with 2.5% synthetic wax. The experiment was designed according to the 3(3−1) fractional factorial design.

PFAS Destruction and Air Emissions During Full‐Scale Thermal Reactivation of PFAS‐Laden Granular Activated Carbon From Industrial Sources

open access: yesRemediation Journal, Volume 37, Issue 1, Winter 2026.
ABSTRACT Granular activated carbon (GAC) is widely recognized as a best available technology (BAT) for the removal of per‐ and polyfluoroalkyl substances (PFAS) from both drinking water and wastewater—capable of achieving the low nanogram per liter (ng/L) effluent concentrations required for regulatory compliance.

Hybrid Amyloid–Boron Nitride Aerogels for Lightweight Sound Insulation

open access: yesAdvanced Materials, Volume 38, Issue 47, 21 August 2026.
Amyloid fibrils template the mild formation of boron nitride–rich hybrid aerogels with hierarchical porosity, enhanced BN‐like ordering, and fibril‐reinforced mechanics. These ultralight materials combine thermal stability with strong sound absorption and transmission loss, offering a sustainable bio‐assisted route toward lightweight acoustic shields ...

Foamed Bitumen Characterization Techniques

open access: yes, 2020
In soil stabilization and pavement recycling, the expansion ratio and half-life parametershave been considered to defne foamed bitumen quality relatively well. However, when applyingfoamed bitumen technology in the production of warm mixtures, these properties are determinedto be insufcient to characterize the foam and guarantee complete aggregate ...
