Effects of ice-wedge degradation and warming on Arctic tundra vegetation across a climatic gradient using a nitrogen-based model

Arctic, Antarctic, and Alpine Research
Ice-wedge polygons in Arctic tundra landscapes influence hydrology, nutrients, thermal regimes, and vegetation. Ice-wedges are particularly vulnerable to warming events, and widespread degradation has been observed in recent decades.

Perturbations in the carbon budget of the tropics [PDF]

, 2014
The carbon budget of the tropics has been perturbed as a result of human influences. Here, we attempt to construct a ‘bottom-up’ analysis of the biological components of the budget as they are affected by human activities.

Multimodal Soft Surgical Robots Enabled by Eco‐Degradable, Sterilizable Polymers and Transient Electronics

Advanced Functional Materials, EarlyView.
A compostable PGS soft surgical robot with interchangeable modules integrates transient Mo tactile and Si thermal sensors for dual feedback. The device preserves its function after clinical‐grade sterilization, demonstrates stable actuation and cardiac tissue grasping with real‐time in vivo pulsatile monitoring, and biodegrades post‐use with soil‐safe,

Homogenous FACsPbI3 Perovskite Solar Cells Enabled by a Seed‐Facilitated Cation Exchange Strategy

Advanced Functional Materials, EarlyView.
A novel seed‐facilitated cation exchange strategy is designed for homogenous FACsPbI3 perovskites using the biomass‐derived solvent γ‐valerolactone. Pre‐deposited 0D Cs4PbI6 seeds induce rapid nucleation and efficient cation exchange, producing a uniform FA–Cs distribution and significantly reducing defect density, enabling high‐performance and stable ...

Thermal behavior of native, washed and steam exploded lignocellulosic biomass samples [PDF]

, 2013
The aim of this study was to evaluate the chemical changes in the main components (cellulose, hemicellulose and lignin) of various lignocellulosic biomass samples during the steam explosion pretreatment. Pyrolysis-gas chromatography/mass spectrometry (Py-

Halotolerant microbial consortia able to degrade highly recalcitrant plant biomass substrate [PDF]

Applied Microbiology and Biotechnology, 2018
The microbial degradation of plant-derived compounds under salinity stress remains largely underexplored. The pretreatment of lignocellulose material, which is often needed to improve the production of lignocellulose monomers, leads to high salt levels, generating a saline environment that raises technical considerations that influence subsequent ...

Endophytic Actinomycetes as Potential Producers of Hemicellulases and Related Enzymes for Plant Biomass Degradation

Brazilian Archives of Biology and Technology
Tailor made enzymatic preparation must be design to hydrolyze efficiently plant biomass, once that each plant biomass possesses a distinct cell wall composition. Most of actinomycetes used for plant cell wall degradation are focused on the cellulases and
