Ngarrawa (mound spring) sediments as archives of Holocene environmental change in arid central Australia: Insights from Itrax XRF scanning

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Central Australia's ngarrawa, or ‘mound springs’, are unique hydrological systems that serve as some of the only near‐permanent sources of water and continuous sediment deposition in Australia's arid interior. As such, they hold significant potential as palaeo‐climate and ‐environmental archives in a region where many aspects of past climate ...

Raman Spectroscopy and Generative Variational Autoencoders for Metallurgical Coke Quality Prediction

open access: yesJournal of Raman Spectroscopy, EarlyView.
An integrated soft sensor framework combining standardized Raman spectroscopy, synergy‐vector feature selection, variational autoencoder‐based data augmentation, and regression models (kNN, PLS, and SVR) predicts metallurgical coke quality (CSR and DI).

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.

Energy Options to Reduce Deforestation Using EKC Model: A Region‐Based Longitudinal Approach

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Forests are carbon storage that can reduce carbon emissions, so deforestation (decrease in forest area) is a serious threat to environmental sustainability. Indonesia is a large carbon sink due to its large forests. However, deforestation is quite high due to economic activities that use fossil energy.

Modified Biochar for Wastewater Nutrient Recovery and Slow‐Release Fertilization in Sandy Agroecosystems

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Modified biochars are increasingly recognized as multifunctional materials for wastewater nutrient recovery and slow‐release fertilization in sandy agroecosystems. This review evaluates modified biochars, with particular emphasis on tyre‐derived biochar (TBC), for (i) recovery of nitrogen (N) and phosphorus (P) from wastewater and digestate ...

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.

Machine Learning‐Assisted Prediction and Analysis of Viscosity and Fusion Characteristics for Coal and Biomass Ash

open access: yesMaterials Genome Engineering Advances, EarlyView.
This study develops a machine learning framework for predicting the flow temperature and viscosity of coal and biomass ash with CatBoost and LightGBM as the optimal models. Feature analysis revealed composition‐property mechanisms, and symbolic regression was further applied to derive empirical formulas for rapid and accurate prediction.

Spent Artemisia arborescens as a Biowaste Filler for Melt‐Processed PBSA Biocomposites With Enhanced Disintegration and Aerobic Biodegradation

open access: yesPolymer Composites, EarlyView.
Spent Artemisia arborescens biomass, recovered after essential‐oil steam distillation, was ground and melt‐compounded with PBSA (10 and 20 wt%), yielding biocomposites with accelerated biodegradation. ABSTRACT Artemisia arborescens is a Mediterranean shrub widely used for essential oil production, generating significant amounts of spent biomass after ...
