Critical technologies in the construction of underground artificial chamber for compressed air energy storage systems

open access: yesDeep Underground Science and Engineering, EarlyView.
This schematic illustrates an artificial chamber‐based compressed air energy storage system. Excess electricity compresses air into sealed underground chambers. During demand peaks, pressurized air is heated, expanded, and drives turbines to generate power.

Lake–Groundwater Biogeochemical Interactions in a River‐Delimited System: The Groundwater and Lakes Urban Observatory (GLUO)

open access: yesInternational Review of Hydrobiology, EarlyView.
ABSTRACT Preservation of urban aquatic ecosystems is of primary importance for human well‐being, biodiversity protection and the future of society. Lake–groundwater–river interactions within urban floodplains harbour intrinsic fragility, yet remain largely understudied.

The Pace di Siena and its Gems

open access: yesJournal of Raman Spectroscopy, EarlyView.
For the first time, the gems of the Pace di Siena, a rare en ronde bosse enamel preserved in Arezzo (Italy), have been analyzed using a transdisciplinary approach. The combination of gemmology and Raman spectroscopy has led to the identification of blue sapphires and pink spinels, contradicting previous historical classifications.

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Mono(2‐Ethylhexyl) Phthalate Induces Inflammatory and Angiogenic Alterations Mediated by the PI3K/AKT Pathway in HTR‐8/SVneo Trophoblastic Cells

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Exposure to mono(2‐ethylhexyl) phthalate (MEHP) during pregnancy has been associated with adverse pregnancy and birth outcomes characterized by extravillous trophoblast (EVT) abnormal function. Previous reports have suggested that MEHP can activate the PI3K/AKT pathway in EVT cells, a pathway known to regulate inflammation and angiogenesis in ...

Evaluating the Microstructure and Interaction of Bioaggregates in Concrete Using microCT

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT This study investigates the use of x‐ray computed microtomography (microCT) to evaluate the incorporation of bioaggregates—specifically macauba (Acrocomia aculeata) endocarp and jute fibers—into cement‐based composites. MicroCT enables non‐destructive, three‐dimensional characterization of the internal microstructure, providing insights into ...

The Oldest Traces of Alcoholic Beverages in the Border Zone of the North and East European Plains

open access: yesArchaeometry, EarlyView.
ABSTRACT Analysis of organic compounds preserved on pottery from the Bell Beaker community and the initial phase of the Trzciniec Cultural Sphere in the border zone of the Eastern and North European Plains was prompted by traces of alcoholic beverages found in contextually and formally analogous discoveries of more westerly provenance.

Micrography and XRF Techniques to Investigate Protohistoric Gold Artifacts: The Case of Roca Vecchia (Lecce, Italy)

open access: yesArchaeometry, EarlyView.
ABSTRACT Protohistoric gold findings from the archaeological site of Roca Vecchia (Melendugno, Lecce, Italy) are analyzed involving micrography and stratified XRF analysis. This exploitation allows to get a deeper insight into ancient gold manufacturing and wear processes adopted in the Southern Italian FBA.

Multispectral Data and LiDAR for Enhanced Georeferencing of Gdanska Glowa's 17th‐Century Fortifications

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents a novel remote sensing method to detect 17th‐century environmental elements associated with the historical fortifications of Gdanska Glowa in Poland. By integrating 10‐band multispectral imaging, high‐resolution (1 m) digital elevation models, vegetation metrics and random forest classification within Google Earth Engine ...
