Optical shrinkage curve characterization as a tool for assessing cyclic wetting-drying effects on hydraulic conductivity of fine-grained soils [PDF]

open access: yesE3S Web of Conferences
Understanding shrinkage behaviour in soft soils is essential for assessing structural and hydraulic stability under environmental stress. This study applies a shrinkage-curve-based method to evaluate soil behaviour before and after cyclic wetting-drying.

Comparative Study of Shrinkage and Non-Shrinkage Model of Food Drying [PDF]

open access: yesJournal of Physics: Conference Series, 2016
A single phase heat and mass model has always been used to represent the moisture and temperature distribution during the drying of food. Several effects of the drying process, such as physical and structural changes, have been considered in order to increase understanding of the movement of water and temperature.

Feasibility and Limitations of the Advanced Replica Process for Bioactive Glasses

open access: yesAdvanced Engineering Materials, EarlyView.
Periodic 3D‐printed Kelvin‐cell templates enable a controlled advanced replica process for fabricating highly porous glass lattices. Across P45K9, 45S5, and 13–93, material‐dependent differences in coating, burnout, and shrinkage lead to distinct strut morphologies, while comparable final porosities of 83%–88% are retained.
