Behavior of high strength self compacted concrete deep beams with web openings

open access: yesHeliyon, 2019
Deep beams transfer loads through loading face to supports in an inclined direction and mostly fail in shear. These beams are with a small span-to-depth ratio. Openings are used to facilitate the passage of utility pipes and service ducts.

Mechanistic Insights into the Structural Evolution of ZIF‐67 via Electrospinning Strategy Toward High Electromagnetic Wave Absorption Performance of ZIF‐67‐Derived Carbon Nanofibers

open access: yesAdvanced Science, EarlyView.
With 5G and AI robotics rising, electromagnetic radiation risks signal security and health. This work investigates the electromagnetic wave absorption of Co/CNF composites via in situ and ex situ electrospinning strategies. The in situ synthesized sample exhibits superior absorption properties due to enhanced structural uniformity, improved Co ...

Hydrolyzable Bio‐Based Bisphenols Enabled by the Tishchenko Reaction for Polyurethane Vitrimers with Closed‐Loop Recyclability

open access: yesAdvanced Science, EarlyView.
This study employs the Tishchenko coupling reaction to obtain bio‐based bisphenols containing degradable ester bonds with 100% atom utilization. Based on these bio‐based bisphenols, a fully bio‐based polyurethane Covalent Adaptable Networks are constructed, while simultaneously endowing the material with closed‐loop recyclability, degradability, and ...
