Stability of Expansive Soil Slopes under Wetting–Drying Cycles Based on the Discrete Element Method

open access: yes
The swelling-shrinkage behavior of expansive soils under climate changes will cause the crack development, which can be destructive of expansive soil slopes.

Impact of weathering on a cement-treated sand [PDF]

open access: yesE3S Web of Conferences
This study’s main goal was to examine how the wetting/drying solicitations affect the mechanical behavior of a cementtreated sand. A quantitative method based on the stress-dilatancy approach was used to assess the effects of two types of wetting and ...

Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

open access: yesAdvanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

Chloride transport in estuarine ship-lock concrete structure exposed to a unique seawater corrosive environment with low chlorine-salt concentrations and high-frequency drying‒wetting cycles: Experimental study and computational model

open access: yesApplied Ocean Research
Estuarine ship-locks are the navigational structures closest to the sea, which can form a unique seawater corrosive environment characterized by low chlorine-salt concentrations and high-frequency drying‒wetting cycles.

Upcycling Keratin‐Based Textile Waste Into High‐Performance Hybrid Fibers Via Tuning the Interfacial Interactions

open access: yesAdvanced Functional Materials, EarlyView.
Keratin recovered from animal‐hair textile waste is fractionated and blended with cellulose to produce continuously spun hybrid fibers. Selecting the high‐molecular‐weight keratin fraction enables 30 wt.% keratin incorporation while maintaining high strength in dry and wet states.
