Interaction mechanisms between organic and inorganic phases in calcium silicate hydrates/poly(vinyl alcohol) composites [PDF]

, 2019
Poly (vinyl alcohol) (PVA) emulsion is commonly used in cement-based materials to obtain higher performance. The present work investigates the interaction mechanisms between PVA and calcium silicate hydrates (C-S-H) using ambient and high pressure X-ray ...

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

VIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.

Time‐resolved synchrotron X‐ray total scattering of alkali‐activated materials with high and low calcium contents

Journal of Synchrotron Radiation, EarlyView.
Synchrotron in situ high‐energy X‐ray total scattering/pair distribution function (PDF) analysis quantifies the time‐resolved structural evolution of high and low calcium alkali‐activated binders, with PDF peak evolution tracking reaction progress and correlating with calorimetry (R2 > 0.97).

Automated particle analysis of D.B. Cooper's tie

Journal of Forensic Sciences, EarlyView.
Abstract Automated particle analysis (APA) using scanning electron microscopy (SEM) and energy‐dispersive x‐ray spectrometry (EDS) is a well‐known method in forensics, especially as it is applied to gunshot residue analysis. Here we describe the analysis of particles lifted from D.B. Cooper's tie, which was left on the hijacked plane in 1971.

What Outcomes Matter in Vital Pulp Therapy? Current Concepts and Challenges

Australian Dental Journal, EarlyView.
ABSTRACT Vital pulp therapy (VPT) has re‐emerged as a practical and biologically sound alternative for managing deep caries and carious pulp exposures. Although its clinical use is now widespread, the outcomes used to judge the success of VPT remain inconsistent and often difficult to compare across studies.
