Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

open access: yessteel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

Can ZooMS Help Assess Species Abundance in Highly Fragmented Bone Assemblages? Integrating Morphological and Proteomic Identifications for the Calculation of an Adjusted ZooMS-eNISP

open access: yesPaleoAnthropology
Zooarchaeology by Mass Spectrometry (ZooMS) is a rapid, low-cost, collagen-based method for the taxonomic identification of animal tissues. It is now increasingly applied to bone fragments from archaeological contexts, creating large taxonomic datasets ...

Portable, Benchtop and Micro‐XRF in Agriculture—Present and Future From the Hardware Perspective

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray fluorescence (XRF) spectrometry has been an important tool in agricultural studies recently. This technique allows the multielemental, direct, and in situ analysis. The objective of this review is to evaluate the use of XRF in agriculture focusing on plant and soil samples based on indexed articles in the Scopus database from 2020 to ...

Sensitivity of continuous emitters to solid particle obstruction [PDF]

open access: yesEngenharia Agrícola
Increasing crop productivity relies on techniques such as irrigation; however, drip irrigation systems face recurrent challenges related to dripper clogging, particularly in continuous emitters used in annual crops. Among these challenges, obstruction by

Toward Silica‐Free Compliance: A Low‐Viscosity Sample Pretreatment Methodology for Crystalline Quartz Quantification in Viscous Pastes

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Crystalline quartz, the most common crystalline silica polymorph, is widely found in industrial products. It is of high regulatory relevance, because its fine fraction, a form of respirable crystalline silica, is classified as an occupational carcinogen, with product‐content thresholds (e.g., 0.1% (w/w) in the European Union) and stringent ...

Neural Networks and Multivariate Analysis Based on Geochemical Data to Determine Stone Provenance From Ancient Calabrian Quarries (Southern Italy)

open access: yesArchaeometry, EarlyView.
ABSTRACT This study shows an innovative approach to determine the origin of some Calabrian rocks quarried used in ancient times. Twenty‐five quarries, distributed in all the Calabrian provinces (Southern Italy), were studied and sampled. Ten samples were taken from each quarry, for a total of 250 samples.
