Diffusion-reaction model for alkali-silica reaction in concrete [PDF]

, 2013
A new diffusion-reaction model for the potentially deleterious Alkali-Silica Reaction (ASR) process in concrete is presented. The model involves three coupled diffusion processes, two in-goingand one out-goingfrom the aggregate viewpoint. Alkali (Na+ and

3D Concrete Printing of Triply Periodic Minimum Surfaces for Enhanced Carbon Capture and Storage

Advanced Functional Materials, EarlyView.
A 3D‐printable and carbon‐capturing concrete is developed by replacing cement with diatomaceous earth (DE), which enhances rheology, provides hierarchical porosity, and serves as a nucleation site for carbonation. Maximum absorption of 488.7 gCO2 kgcement−1 is achieved in 7 days, a 142% increase over conventional concrete, and the triply periodic ...

The use of Bioceramics as root-end filling materials in periradicular surgery: a literature review [PDF]

, 2018
Introduction: Periradicular surgery involves the placement of a root-end filling following root-end resection, to provide an apical seal to the root canal system. Historically several materials have been used in order to achieve this seal.

The Deepest Blue: Major Advances and Challenges in Deep Blue Emitting Quasi‐2D and Nanocrystalline Perovskite LEDs

Advanced Materials, EarlyView.
In this review, the recent development of deep‐blue (≤465 nm) perovskite light‐emitting diodes (PeLEDs) are summarized, using different perovskite nanomaterials, including nanocrystals (NCs), quantum dots (QDs), nanoplatelets (NPLs), quasi‐2D thin film, 3D bulk thin film, as well as lead‐free perovskite nanomaterials.

Untangling the Role of Capping Agents in Manipulating Electrochemical Behaviors Toward Practical Aqueous Zinc‐Ion Batteries

Advanced Materials, EarlyView.
Inspired by the critical role of capping agents in nanomaterials synthesis and bulk crystal growth, the role of capping agents in manipulating the electrochemical behaviors of AZIBs is untangled. The multifunctional role of the capping agents in terms of the Zn anode, electrolyte, and cathode validates stable and practical AZIBs. Abstract Long‐standing

Raman spectroscopic study of the mineral xonotlite Ca6Si6O17(OH)2 - A component of plaster boards [PDF]

, 2012
The mineral xonotlite Ca 6Si 6O 17(OH) 2 is a crystalline calcium silicate hydrate which is widely used in plaster boards and in many industrial applications. The structure of xonotlite is best described as having a dreierdoppelketten silicate structure,

A Bio‐Inspired Perspective on Materials Sustainability

Advanced Materials, EarlyView.
This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...

Order and disorder in calcium–silicate–hydrate [PDF]

The Journal of Chemical Physics, 2014
Despite advances in the characterization and modeling of cement hydrates, the atomic order in Calcium–Silicate–Hydrate (C–S–H), the binding phase of cement, remains an open question. Indeed, in contrast to the former crystalline model, recent molecular models suggest that the nanoscale structure of C–S–H is amorphous.
