Building envelope such as external walls are still constructed from poor materials which results in higher heating and cooling loads thereby raising energy bills. Improving building efficiency with advanced technologies is being sought. In this context, a numerical study was conducted to solve the coupled heat transfers through standard wall structure used Libyan residential buildings. Differen...

When a commercial vehicle diesel engine works for an extended period of time at the torque spot, it can easily cause mechanical failure due to high temperature piston. In this paper, plug method was used measure piston maximum spot. order reduce caused by temperature, finite element analysis software Ansys in paper study effects different thicknesses ceramic coatings on surface substrate. The b...

This work evaluates the performance of cement-based composites made with rice husk and intended to be used in acoustic barriers as thermal insulating material a multilayer system. Because are exposed external conditions mechanical loads, wide range laboratory tests were performed evaluate mechanical, durability characteristics composites. Their specific heat capacity conductivity evaluated when...

An optically transparent and thermally insulating (OTTI) silica aerogel demonstrates promising results for various solar thermal applications, particularly concentrated power systems. Higher system efficiency can be achieved by integrating OTTI materials reducing heat loss at higher receiver temperature. However, the stability of aerogels has been one limiting factors. Here, we report that Al2O...

Sustainable coating solutions that function as a fire retardant for wood are still challenging topic the academic and industrial sectors. In this study, composite coatings of casein protein mixed with mica aluminum trihydroxide (ATH) were tested retardants plywood; degradation retardancy performance assessed cone calorimeter, thermogravimeter was used thermal stability measurement. The results ...

Colossal electroresistance (CER) has been observed in the ferromagnetic insulating (FMI) state of a manganite. Notably, the CER in the FMI state occurs in the absence of magnetoresistance (MR). Measurements of electroresistance (ER) and current induced resistivity switching have been performed in the ferromagnetic insulating state of a single crystal manganite of composition Nd0.7Pb0.3MnO3 (NPM...

On the basis of National Research University "MPEI", within framework project to create a busbar with polymer-gas insulation for transmission electricity from offshore wind turbines, study is being carried out develop insulating structures high-voltage busbars. The work devoted development and justification design special conductor combined (polymer-gas) laying in sea water electrical energy wh...

An innovative method against late frosts in vineyard has been developed at CIRIAF, University of Perugia. It consists an organic coating made by cotton candy and straw to prevent the vine shoots freezing due frosts. This technique already tested lab-scale with very encouraging results. paper aims experiment effect applied on young grapevine during artificially controlled frost events. A shoot c...
