The article deals with studying the effect of lignin on the thermal conductivity of the finished phenolic foam. Lignin was introduced at the mixing stage when obtaining phenolic foam. The properties of the phenol-formaldehyde resin and lignin used in the work as well as a method for determining the thermal conductivity of a thermal insulation mater...

This experimental study provides complete datasets of hygrothermal properties of numerous hemp-clay with density ranging from 200 to 350 kg m-3 for building thermal insulation. In addition, attention is also paid on protocols and methods, on the measurements repeatability and on the influence of conditioning temperature and relative humidity: mean ...
Appropriate sand for construction is getting scarce in many countries leading to a growing interest in the use of wastes from several origins in mortar and concrete production. This paper investigates the performances of mortar containing the industrial wastes of vegetable synthetic sponges (VSS) as natural sand replacement. After preparation, diff...

The high-pressure (HP) turbine and compressor blades are subjected to severe aero-thermal loads either caused by high inlet temperature resulting from the combustion chamber or by the shock wave at the blade surface. In this paper, a partitioned conjugate heat transfer (CHT) approach is used to assess 3D cases with high temperature gradient. On one...
During the last decades, mid-infrared (3-12 μm) laser sources using crystals with nonlinear optical properties have attracted a particular attention due to their potential applications in different fields such as optical countermeasures and remote chemical sensing. As transparency of common oxide crystals is limited to about 4 μm, many researches h...

This paper reviews the thermal conductivity (TC) enhancement of transparent and flexible polymer composites. Poly-dimethyl siloxane (PDMS), polyethylene terephthalate (PET), and polyimides (PI) are considered. The physical properties of these polymers reinforced with many highly conductive fillers have been investigated by both experimental and num...
