By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...

Predicting Forest Age up to 250 Years in Old-Growth Boreal Mixedwoods of Western Quebec, Canada, Using Airborne Laser Scanning Data and Modelled Tree Species Composition

open access: yesCanadian Journal of Remote Sensing
Old-growth boreal forests play a key role in global conservation policies. Forest age maps, however, tend to lose accuracy as stands age, making it impossible to consider the full successional diversity of old-growth forests.

Biodiversity and biomass co‐regulate urban forest drought resistance

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Severe droughts induced by climate change present substantial challenges to urban forests. While the role that species richness plays in enhancing drought resistance in natural ecosystems has been highlighted in previous studies, its impact within urban forests remains less understood.

Nitrogen oxides and PAN in plumes from boreal fires during ARCTAS-B and their impact on ozone: an integrated analysis of aircraft and satellite observations [PDF]

open access: yes, 2010
We determine enhancement ratios for NO_x, PAN, and other NO_y species from boreal biomass burning using aircraft data obtained during the ARCTAS-B campaign and examine the impact of these emissions on tropospheric ozone in the Arctic.

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

open access: yesFlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Multi‐synergistic strategy for dual‐sensing conductive hydrogels capable of simultaneous strain and temperature monitoring

open access: yesFlexMat, EarlyView.
In this study, a multicomponent synergistic strategy is utilized, which capitalizes on the “intersection” of multiple functional influencing factors to achieve the successful development of a multifunctional hydrogel. Through the construction of a unique three‐dimensional dynamic cross‐linked network, the material combines mechanical strength ...
