A Fractal Link Between Soil Water Retention and Freezing

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Soils undergo wetting‐drying and freezing‐thawing cycles, yet their water retention and freezing behaviors are typically described within separate frameworks. This separation raises a fundamental question: do desaturation and freezing share comparable pore‐structure controls?

The effects of cracks on the movement of Ca+2 within gold refining residue [PDF]

, 1997
Gold refining residue is alkaline (pH> 9), saline (EC1:5: 800- 1100 mS/m) and sodic (ESP>60) (Ho et al., 1998). These chemical properties have a detrimental effect on residue physical properties (hydraulic conductivity, bulk density, porosity).

Biomimetic Design of Biopolymer‐Based Water‐Resistant Food Packaging Materials

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT With the growing demand for sustainable and eco‐friendly food packaging, biopolymer‐based materials are emerging as promising candidates due to their recyclability, biodegradability, and food safety. However, in practical applications dealing with high moisture content or perishable foods, their lack of water resistance poses a significant ...
