Modeling Suffusion in Porous Media Using a Particle Scale Linear Decay Function

open access: yesWater Resources Research
Suffusion with migration of fine particles (fines) in pores is a common subsurface hydrological process in nature, which has significant impacts on breaching of dikes, dam failure, and hillslope instability.

Photon Avalanching Nanoparticles: The Next Generation of Upconverting Nanomaterials?

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective outlines the mechanistic foundations that enable photon‐avalanche (PA) behavior in lanthanide nanomaterials and contrasts them with emerging application spaces and forward‐looking design strategies. By bridging threshold engineering, energy‐transfer dynamics, and materials engineering, we provide a coherent roadmap for advancing the ...

Does Immigration Increase Economic Growth? [PDF]

open access: yes, 2014
The question of how many legal immigrants should be admitted to the United States -- and what level of skills these immigrants should have --is among the most divisive issues in the current U.S. domestic policy landscape.

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.

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

open access: yesAdvanced 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

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

open access: yesAdvanced 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 ...

Influence of recovery model of coalbed methane wells after drainage interruption on coal fines migration in propped fractures

open access: yesMeikuang Anquan
In the drainage process of coalbed methane well, the interruption of drainage will induce a large amount of coal fines to stay in propped fractures, causing damage to the permeability of propped fractures. Based on the solid-liquid two-phase flow and gas-

Life in the Atacama — Year 2: Geologic reconnaissance through long-range roving and implications on the search for life [PDF]

open access: yes, 2005
The Life in the Atacama-2004 project, which included geological, morphological, and mineralogical mapping through combined satellite, field-based, and microscopic perspectives and long-range roving, led to the localization of potential ...
