Smart Firefighters PPE: Impact of Phase Change Materials

Nano-Encapsulated Smart Tunable Phase Change Materials

Phase change materials for smart textiles – An overview

Phase change materials (PCM) take advantage of latent heat that can be stored or released from a material over a narrow temperature range. PCM possesses the ability to change their state with a certain temperature range. These materials absorb energy during the heating process as phase change takes place and release energy to the environment in the phase change range during a reverse cooling pr...

[Risk perception, use of PPE and injuries among firefighters].

INTRODUCTION The present study, situated in the safety at work issue, is aimed to evaluate the risk perception and preventive behaviour (the use of individual protection devices) in the fire brigade work, with reference to the most typical risk for these workers: cylinder blast; fire and exhalation of toxic steam; road accidents; falls, cuts, contusions; stress and physical strain. To this end ...

Thermal Transport in Phase Change Memory Materials

Phase change memory uses brief pulses of electrical current to induce phase transitions in chalcogenide material regions with dimensions near or even far below 50 nm. The strongly differing electrical conductivities of the crystalline and amorphous phases allow data storage at densities in excess of terabits per square inch. Nanoscale conduction heat transfer governs the figures of merit in the...

Thermal Management Using “ Dry ” Phase Change Materials

The thermal response characteristic of a hybrid cooler that is charged with a “dry” solid-solid phase change compound is evaluated. A mathematical model that simulates the performance of a cooler/heat storage unit is formulated. A prototype heat sink that incorporates heat storage using a “dry” PCM is tested, and used to benchmark the simulation model. Different heating and cooling strategies a...
