Deflagration characteristics of freely propagating flames in magnesium hydride dust clouds

Defence Technology
The flame propagation processes of MgH2 dust clouds with four different particle sizes were recorded by a high-speed camera. The dynamic flame temperature distributions of MgH2 dust clouds were reconstructed by the two-color pyrometer technique, and the ...

Gamma-ray bursts and X-ray melting of material as a potential source of chondrules and planets [PDF]

, 2004
The intense radiation from a gamma-ray burst (GRB) is shown to be capable of melting stony material at distances up to 300 light years which subsequently cool to form chondrules.

High‐Entropy Alloy Design Toward Cobalt Substitution for High Hardness and Low Wear Rate Using X–Cr–Fe–Mn–Ni System

Advanced Engineering Materials, Volume 28, Issue 2, January 21, 2026.
This study explores the replacement of cobalt using the high‐entropy alloy design strategy for wear‐resistant components operating at high temperatures. Starting from the Cantor alloy, cobalt is substituted with Cu, Al, V, or Mo. Metallurgical and tribological analyses reveal that aluminum, vanadium, and molybdenum effectively strengthen the developed ...

Harnessing Outer Space for Improved Electrocaloric Cooling

Advanced Functional Materials, Volume 36, Issue 6, 19 January 2026.
A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

High‐Performance n‐type Organic Thermoelectric Aerogels Toward Flexible Energy Harvesting and Sensing Devices

Advanced Electronic Materials, Volume 12, Issue 2, 21 January 2026.
An n‐type organic thermoelectric aerogel PB@CNF, based on PBFDO, is fabricated by a two‐step freeze‐drying process with cellulose nanofiber (CNF) as substrate. The aerogels can be used not only as temperature sensing and piezoresistive sensing, but also to form a flexible organic thermoelectric generator with the p‐type aerogel (PH@CNF) based on PEDOT ...

Surface Temperature Measurement with Unknown Emissivity Using a Two-color Pyrometer Placed with a Reflector

IOP Conference Series: Materials Science and Engineering, 2018
An instrument for measuring surface temperature above 773 K has been developed. A gold-plated reflector is placed ahead of a two-color pyrometer. When the reflector is positioned facing the measured target, the received radiation is increased, and the difference between the effective emissivities of the two received wavelengths is shortened.
