Heterogeneous ice nucleation correlates with bulk-like interfacial water

Science Advances, 2019
Bulk-like interfacial water, a sub-ensemble of interfacial water, can be a predictor for heterogeneous ice nucleation. Establishing a direct correlation between interfacial water and heterogeneous ice nucleation (HIN) is essential for understanding the ...

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

Molecular Templating Enables Precise CeNiC2/Ni Heterostructures for Efficient Alkaline Hydrogen Oxidation

Advanced Functional Materials, EarlyView.
A series of Bi‐TMCs‐based heterostructures (CeNiC2/Ni‐x%) have been precisely constructed through a “molecular‐template”‐assisted strategy, which exhibits remarkable alkaline HOR performance derived from the strong synergy between Ni and CeNiC2 components.

A comprehensive study of impact of solid particles on scaling formation and inhibition in oilfield water

Desalination and Water Treatment
Oilfield production water is a multiphase complex system, and the scaling process should be influenced by other components. However, current research on scaling and scale inhibition has been conducted while neglecting other components, which may lead to ...

Heterogeneous Nucleation in and out of Pores

Physical Review Letters, 2006
We study the nucleation of a new thermodynamic phase in pores and find that the nucleation often proceeds via two steps: nucleation of pore filling, and nucleation out of the pore. These two rates have opposing dependencies on pore size, resulting in a pore size at which the nucleation rate of the new phase is maximal.

Understanding the Role of Superhydrophobicity and Superhydrophilicity in Salt‐Spray Corrosion of Nanosecond Pulsed Laser‐Textured AA2024 Alloy

Advanced Functional Materials, EarlyView.
Nanosecond pulse laser texturing yields superhydrophobic and superhydrophilic AA2024 surfaces. Salt‐spray tests show that periodic superhydrophobic patterns suppress pitting, whereas superhydrophilic textures enhance it, linking laser‐induced morphology, wettability, and oxide chemistry to corrosion resistance.

LL‐37 Driven Phase Transition and Stacking in Oligolamellar Gram‐Negative Bacterial Membrane Models

Advanced Functional Materials, EarlyView.
This work establishes oligolamellar bacterial membrane models to investigate how LL‐37 disrupts the complex dual‐bilayer architecture of Gram‐negative bacteria. Combining SAXS, cryo‐TEM, electrophoretic mobility measurements, and coarse‐grained simulations, it reveals cardiolipin‐driven phase transitions leading to bicelle‐like structures and membrane ...

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

Advanced Functional Materials, EarlyView.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

Technical Note: The heterogeneous Zeldovich factor [PDF]

Atmospheric Chemistry and Physics, 2007
In this technical note we present the exact form of the Zeldovich factor for heterogeneous nucleation on spherical pre-existing particles. We study the error caused by planar pre-existing surface approximations, which have been used in our earlier ...

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

Advanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...
