Gels for CO2 geo‐storage and conformance control: A systemic review of behavior and performance

open access: yesDeep Underground Science and Engineering, EarlyView.
This review provides a systemic evaluation of potential sealants used in CO2 subsurface storage practices. Critical analyses of how external factors like CO2, pH, brine salinity and hardness, rock mineralogy, pressure, temperature, and injectivity could affect the performance of different sealants are provided. Abstract Carbon capture and storage (CCS)

A review on rockburst prediction and prevention to shape an ontology‐based framework for better decision‐making for underground excavations

open access: yesDeep Underground Science and Engineering, EarlyView.
A scientometric analysis of 2449 journal articles and a comprehensive review of 336 papers were conducted, discussing and identifying challenges and research gaps in rockburst prediction and prevention and proposing an ontology‐based framework for better decision‐making in underground excavations. Abstract With underground engineering projects becoming

Predicting Water Cycle Characteristics from Percolation Theory and Observational Data. [PDF]

open access: yes, 2020
The fate of water and water-soluble toxic wastes in the subsurface is of high importance for many scientific and practical applications. Although solute transport is proportional to water flow rates, theoretical and experimental studies show that heavy ...

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).

Effect of Solution Temperature on the Microstructure of 18%Ni Maraging Steel Modified With Nb—X‐Ray Diffraction and Electron Backscattered Scanning Diffraction (EBSD) Analyzes

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Maraging steels are high strength alloys used in applications that require both high mechanical strength and toughness. To achieve these properties, one of the heat treatments applied is solution treatment, although it can reduce toughness.

Printing non-Euclidean solids

open access: yes, 2017
Geometrically frustrated solids with non-Euclidean reference metric are ubiquitous in biology and are becoming increasingly relevant in technological applications. Often they acquire a targeted con- figuration of incompatibility through surface accretion

Softening the "crystal-scaffold" for life's emergence [PDF]

open access: yes, 2011
Del Giudice's group study how water can organize on hydrophilic surfaces forming coherent domains (loaning energy from the quantum vacuum), plus quasi-free electrons, whose excitations produce cold vortices, aligning to ambient fields. Their electric and

Tracing the origin of Roman mosaic tiles in Aquileia: Petrographic analysis of specimens from the suburbium

open access: yesArchaeometry, EarlyView.
Abstract This research represents the most extensive characterisation of Roman mosaic tesserae (tiles) from Aquileia, Italy, to date, examining 153 specimens. The study aimed to identify the lithotypes used in mosaics production through a multi‐analytical approach, which included colorimetric analysis, polarised light microscopy and scanning electron ...
