Rock Mass Anomaly Detection with a Variational Autoencoder in Tunnel Boring Machine Data

open access: yesCivil Engineering Design, EarlyView.
Abstract This study presents an unsupervised machine learning approach to rock mass anomaly detection in tunnel boring machine operational data using a Variational Autoencoder combined with bidirectional Long Short‐Term Memory cells. The model was trained on TBM data from the Brenner Base Tunnel project, with minor faults and geotechnically relevant ...

Weighing risks against GHG reduction benefits in emerging green technologies

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Green technologies represent promising strategies for mitigating carbon emissions and combating global warming. However, their implementation in civil and industrial applications is not without risks, as intrinsic uncertainties and latent safety concerns can threaten their effective deployment.

Phase Transformation Processes in Coprecipitated Cu/Zn/Zr Methanol Catalyst Precursors—Insights into Suspension Aging Form Ultrafast Nucleation

open access: yesChemPlusChem, EarlyView.
Catalyst production for methanol synthesis includes an aging step. By ultrafast nucleation, occurring transient changes in the suspension important for later performance can be assessed. Analytical techniques deliver insights which lead to a mechanism in which zincian malachite is the main product, whereas a sodium species play an important role as ...

Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

open access: yesThe Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.
