The effect of hygrothermal conditions (air temperature and relative humidity) on the dehydration of theophylline monohydrate was investigated. Firstly, the equilibrium states of theophylline were investigated. The data from gravimetric analysis at constant temperature and humidity were reported as desorption isotherms. The PXRD analysis was used to identify the different polymorphic forms of th...

The majority of contemporary insulation materials commonly used in the building industry is made from non-renewable raw materials; furthermore, their production often brings high energy costs. A long-term trend as far as sustainable development is concerned has been the reduction of energy and material demands of building material production. One of the solutions is the possibility of using eas...

In the present study, abrasive wear tests were conducted to investigate effect of hygrothermal ageing on friction and resistance glass/Polytetrafluoroethylene (PTFE) composites. Non-hybrid hybrid composites manufactured with PTFE coated two-dimensional plain weave (2D), three-dimensional knitted (3D), satin (SW) fabrics a steel metal mesh (MM). Hybrid glass MM by placing it top bottom laminate....

• Hygrothermal material properties of bio-based insulators were determined. Bio-based materials provide high thermal resistance and water vapour permeability. Properties insulations are comparable with conventional materials. performance buildings is one key element to the sustainable design, health, comfort indoor environment. Building sustainability depends on all associated lifespan stages, ...

The study investigates through hygrothermal modelling the effect of different boundary conditions and varying measured vapour diffusion resistivity values on performance five pliable membranes. Previously, this research quantified variable water properties building membranes were assessed under humidity using gravimetric wet dry cup test method. better represent experienced by materials in enve...
