Post‐Fire Soil Organic Carbon Dynamics: Decline and Recovery Over Two Decades

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Wildfire can significantly alter soil organic carbon (SOC) dynamics in forest ecosystems, with complex temporal patterns following fire events. However, research on post‐fire SOC recovery remains limited, particularly in dry‐warm valley regions that are prone to frequent forest fires.

Introducing a ramped pyrolysis/oxidation‐14CO2 analysis system operated with mobile molecular sieve traps

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract A novel instrument for the thermal degradation of sedimentary organic matter was set up at the Alfred Wegener Institute (AWI) in Bremerhaven, Germany, with the aim of enabling Ramped Pyrolysis/Oxidation‐14C analysis as direct CO2 gas measurement.

Graded Differential Polynomial Rings

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT We study differential polynomial rings R[t;δ]$R[t;\delta]$ over Γ$\Gamma$‐graded rings, where Γ$\Gamma$ is an arbitrary group. We show that R[t;δ]$R[t;\delta]$ admits a Γ$\Gamma$‐grading compatible with that of R$R$ if and only if δ$\delta$ is a γ$\gamma$‐derivation for some γ∈CΓ(ΓR)$\gamma \in C_\Gamma (\Gamma _R)$, and that this grading is ...

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

open access: yesMacromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

Fluorenone and Fluorenemalononitrile‐Tethered Conjugated Microporous Polymers for Efficient CO2 Uptake and Rhodamine B Removal

open access: yesMacromolecular Rapid Communications, EarlyView.
TPET‐F2CN CMP exhibited higher CO2 uptake (2.88 mmol g−1 at 273 K) and superior Rhd B adsorption, with an equilibrium capacity of 98.12 mg g−1 and a maximum monolayer capacity of 155.6 mg g−1. ABSTRACT Herein, two conjugated microporous polymers (CMPs), TPET‐FO and TPET‐F2CN, are functionalized with carbonyl and nitrile groups.

Thermal and Morphological Analysis of Biocomposite From Multilayer Plastic Waste and Oil Palm Empty Fruit Bunch Fiber

open access: yesMacromolecular Symposia, EarlyView.
ABSTRACT Oil palm empty fruit bunches (OPEFB), a byproduct of the palm oil industry, have great potential in the circular economy, particularly for composite material production. Multilayer plastic waste from the bottled water industry presents significant environmental challenges.

Life‐history traits and phylogeny structure taxon‐specific species–substrate relationships in deadwood

open access: yesOikos, EarlyView.
To understand the structuring of species assemblages, integrating life‐history traits and evolutionary heritage in analyses is vital. This allows the assessment of a mechanistic link between species and their environment. Deadwood systems are vital for nutrient cycling and biodiversity support, governed by complex intra‐ and inter‐specific fungal and ...

Direct Ink Writing 3D Printing of High Graphite Loading Polybenzoxazine Composite

open access: yesPolymer Composites, EarlyView.
Graphite reinforced benzoxazine can be directly printed and crosslinked with help of an inert power support. This allows the graphite particle to form temporary scaffold and the printed shape to be preserved. ABSTRACT Polybenzoxazine is a class of high‐performance thermoset that can be reinforced with graphite to gain great thermal stability, chemical ...
