An improved moisture diffusivity model for porous building materials [PDF]
, 2007 A parametric diffusivity model is proposed to describe accurately the nonlinear diffusivity of porous building materials. To identify the parameters of the diffusivity model, moisture profile measurements during capillary absorption, a global drying ...

Study on Drying Kinetics of Paddy Rice: Intermittent Drying [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2016 The intermittent drying characteristics of an Iranian popular paddy rice variety were experimentally investigated to determine the drying kinetics and obtain the effective moisture diffusivity. A lab-scale fluidized bed dryer was designed and constructed

Advanced Engineering Materials, EarlyView.Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Advanced Engineering Materials, EarlyView.PUF/ENB microcapsules were synthesized based on a sequential factorial design and incorporated into an epoxy matrix. Their anticorrosive action, associated with the self‐healing mechanism, demonstrated that the addition of microcapsules to the coating improved anticorrosive performance compared to pure epoxy coatings, particularly when the encapsulate ...

Determining of moisture diffusivity and activation energy in drying of apricots
Research in Agricultural Engineering, 2009 In this study, Fick's second law was used as a major equation to calculate the moisture diffusivity for apricot fruit with some simplification. Drying experiments were carried out at the air temperatures of 40, 50, 60, 70, and 80°C and the drying air ...

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Evaluation of moisture diffusivity in copra at different drying condition
, 2017 Copra is one of the major traditional products processed from coconuts and is used primarily as a source of coconut oil. It is the kernel of coconut after reducing the moisture content from about 50% (dry basis) to about 6% (dry basis) by drying ...
