Laser Absorption Shock Tube Study of C1 to C4 n‐Alkyl Formate Pyrolysis

International Journal of Chemical Kinetics, Volume 58, Issue 5, Page 199-209, May 2026.
ABSTRACT n$n$‐Alkyl formates are considered as potential alternative fuels or fuel additives. While their oxidation chemistry has been investigated intensely, their pyrolysis chemistry requires more experimental insights. The present work utilizes shock tube experiments in combination with infrared laser absorption measurements to obtain information ...

Effect of Matrix Properties on Quasi‐Static and Fatigue Properties of Thermosetting Polyurethane and Its GFRP Composites

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1929-1943, May 2026.
ABSTRACT In this study, the influence of resin cross‐link density on thermomechanical properties and fatigue behavior of polyurethane resins and glass fiber‐reinforced polyurethane (PUR‐GFRP) composites was investigated. This material is a candidate for renewable energy applications like rotor blades in wind turbines.

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

Advanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed
