Water pathways and ancient lakes: Flowing towards new models to unravel the past

open access: yesThe Depositional Record, EarlyView.
Abstract Significant progress has been made in understanding lake basin evolution through climatic and tectonic changes using sedimentology, sequence stratigraphy, geochemistry, hydrology and watershed characteristics to interpret three main lake basin types: overfilled, balanced‐fill and underfilled, including fluvio‐lacustrine systems.

Ethanol evaporation drives ester assembly and particle deposition in droplets of Chinese distilled liquors

open access: yesDroplet, EarlyView.
The time‐lapse evaporation of 1.0 µL droplets of strong‐flavor Baijiu (upper panel) and sauce‐flavor Baijiu (lower panel) is observed using a dark‐field phase annulus upright microscope. During evaporation, a noticeable phenomenon of particle assembly occurs, and as these particles move and deposit, they finally exhibit distinct Baijiu‐specific coffee ...

Hotspots, trends, and regional focus on oil or gas exploration: A bibliometric comparative study

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper explores the research trends in global oil and gas exploration through the bibliometric analysis of 3460 articles collected from the Web of Science database on oil and gas exploration published from 2013 to 2023. The research hotspots, objects, regional distribution, methods, and evaluation methods of oil and gas exploration are analyzed and

Data‐driven analysis of the spatial dependence of grouting efficiency during tunnel excavation

open access: yesDeep Underground Science and Engineering, EarlyView.
Prediction of grouting efficiency using machine learning is enhanced by adopting a training strategy that accounts for the grouting process across multiple rounds. Abstract Grouting with water–cement mixtures is the most widely used and cost‐effective method for managing excess water inflow during tunnel construction.
