An in situ estimation of the thermal properties bio-sourced building wall insulation components is critical importance improving both energy efficiency buildings and development construction materials with a smaller environmental footprint. Depending on weather conditions, passive methods are not always feasible; they require time to conduct lengthy testing may lead significant uncertainties. T...

According to both the actual energy context and the latest laws meeting EU requirements about energy certification schemes for buildings, carrying out an energy performance diagnosis is mandatory, notably when buying or selling buildings. Indeed, invisible defaults could have a detrimental effect on their insulating qualities. An in-situ estimation of thermophysical properties allowing to locat...

The purpose of this paper is to experimentally study the thermal resistance (RSI value) building insulation materials made mainly from natural fiber. Natural fibrous or renewable resources and their reinforcement composites are currently being used in construction as a potential solution significantly reduce load energy consumption. RSI value describing efficiency insulating material an analysi...

We propose a type of thermal interface materials incorporating insulating nanowires with partially metallic coating in polymer matrix. Large conductivity can be obtained due to percolation while the electrical insulation is maintained by controlling CM?<?ce and ?>?cth, where ? volume fraction fillers, CM fraction, ?ce ?cth are thresholds, respectively. The such composite further r...

Switches and rectification devices are fundamental components used for controlling the flow of energy in numerous applications. Thermal and acoustic rectifiers have been proposed for use in biomedical ultrasound applications, thermal computers, energy- saving and -harvesting materials, and direction-dependent insulating materials. In all these systems the transition between transmission states ...

Using recently calculated analytic models for the thermal structure of ultramagnetized neutron stars, we estimate the thermal fluxes from young (t ∼ 1000 yr) ultramagnetized (B ∼ 10 G) cooling neutron stars. We find that the pulsed X-ray emission from objects such as 1E 1841-045 and 1E 2259+586 as well as many soft-gamma repeaters can be explained by photon cooling if the neutron star possesses...
