Investigation of plastic shrinkage cracking in fiber-reinforced concrete and shrinkage-compensating cement concrete [PDF]

open access: yes, 2020
Excessive pore water pressure development in early-age concrete may lead to plastic shrinkage cracking in a restrained concrete specimen. As the water evaporation rate exceeds the bleeding rate, negative capillary pressure builds in concrete while it is ...

3D‐Printed Titanium Gyroid Scaffold Structure Integrated With Tough Hybrid Materials for Cartilage Replacement

open access: yesAdvanced Engineering Materials, EarlyView.
This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.
