Mineral Deposition From Liquid Precursors Triggered by Complementary Polyelectrolytes

Advanced Functional Materials, EarlyView.
Polyelectrolyte additives can delay or prevent crystal nucleation in supersaturated solutions of insoluble mineral salts such as calcium carbonate. This work reports that adding a second, oppositely‐charged polyelectrolyte leads to immediate mineral crystallization from such metastable solutions.

Chemical Control of Space Charge Barriers and Grain Boundary Resistances in Polycrystalline Ionic Conductors

Advanced Functional Materials, EarlyView.
Grain boundaries (GBs) in polycrystalline materials often block charge transport and drive degradation. Using Gd‐doped CeO2 as a model electrolyte used in fuel/electrolysis cells, we developed a core‐shell infiltration method to selectively modify GB chemistry and space charge potential, achieving orders‐of‐magnitude ionic conductivity changes.

InfraRed NDT for cured prepreg carbon specimens

Proceedings of the 2020 International Conference on Quantitative InfraRed Thermography, 2020
Prepreg laminated composite plates with Teflon inserts and sandwich panel with damaged Coremat were subjected to InfraRed Non-Destructive Testing. Every sample was recorded by means of reflected thermography and raw data were processed by various algorithms: Thermal Signal Reconstruction, Fast Fourier Transformation and Principal Component Analysis.

Encoded Cell‐Material Interactions to Reroute Cytokine Signaling for Regenerative Medicine

Advanced Healthcare Materials, EarlyView.
We present native MATRIX (Material Activated To Regulate Inducible gene eXpression), a co‐engineered material‐cell platform. Surfaces functionalized with antibodies for endogenous soluble ligands (e.g., IL‐1β or IL‐6) capture and immobilize ligands for presentation to a cognate, engineered synthetic Notch receptor, releasing a transcription factor (TF)

Effect of Carbon Dioxide Curing on the Carbonation Durability of Concrete

Frontiers in Sustainable Development
Concrete structures generate a large amount of carbon dioxide(CO2) during the production and construction of raw materials, exacerbating environmental problems such as greenhouse effect. In order to achieve low-carbon and environmentally friendly construction projects, a large number of new technologies and products have been developed to reduce carbon

Tomographic Printing in a Chip: A Versatile Platform for Biomimetic 3D Organ‐on‐Chip

Advanced Healthcare Materials, EarlyView.
A novel light‐based bioprinting approach, TVAM‐in‐a‐chip, enables rapid, contactless fabrication of biomimetic 3D organ‐on‐chip devices directly within preassembled microfluidic platforms. This strategy supports diverse materials, including cell‐laden resins, and eliminates post‐assembly steps.

Preliminary exploration of the hydration-carbonation coupling mechanism of low-carbon calcined clay-carbide slag-cement composites

Journal of CO2 Utilization
To reduce the environmental impact of cement production and carbon emissions, the use of supplementary cementitious materials to replace part of the clinker and carbonation curing are two of the most effective strategies for reducing carbon dioxide ...
