Gas transfer velocity (k600) increases with discharge in steep streams but not in low‐slope streams

open access: yesLimnology and Oceanography Letters
Gas transfer velocity (k600) controls gas fluxes between aquatic ecosystems and the atmosphere. In streams, k600 is controlled by turbulence and, thus, local hydrology and geomorphology.

Impact of Sustainable Binders Based on Lignin and Collagen on the Volume Stability and Mechanical Properties of MgO‐C Refractories with MgO‐C Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Fertilization effects on CH4, N2O and CO2 fluxes from a subtropical double rice cropping system

open access: yesPlant, Soil and Environment, 2019
A 2-year field study was conducted in a double rice cropping system in southern China to examine the effect of fertilization on CH4, N2O and CO2 fluxes using static opaque chambers and gas chromatographs. Two treatments were set up including conventional

Cool Kitchen: Processing Starch and Eggshell Powder into Sustainable Coatings for Passive Daytime Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A food‐grade cooling composite made from starch and recycled eggshell powder offers a scalable, ultra‐low‐cost solution for passive daytime radiative cooling. Easily prepared using basic kitchen tools, this material empowers communities, even in areas with limited infrastructure, to stay cooler during worsening summer heat waves.

Self‐Sintering Ionogel Binder for Flexible, Recyclable, and Healable Printed Giant Magnetoresistive Sensors

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...
