Recent Advances in Recycling of Copper‐Based Waste Materials: A Critical Review

cMat, Volume 2, Issue 2, June 2025.
ABSTRACT Copper plays a crucial role in the civilization of our lives. This review examines the flow of copper from the mining of ores to the end‐of‐life product, with particular emphasis on the recovery and re‐functionalization of copper and copper‐containing wastes. Beginning with the analysis of the global copper market, reserves, supply, and demand,

Effect of nonmetallic inclusions on steel welds metal hot cracking

Metalurgija, 2014
Intercrystally distributed nonmetallic inclusions greatly increase weld susceptibility to hot cracking. Oxide and sulphide inclusions are the result of contaminated base material or its highly oxidised surfaces and they can be a consequence of ...

Low temperature vaporisation of Cr from fluoride flux reacted at 1350 °C with Al–Cr–Fe powder: Thermochemical analysis of gas phase reactions and nano-strand formation

Journal of Materials Research and Technology
The submerged arc welding (SAW) process is complex because multi-phase reactions occur simultaneously across a large temperature interval from 2500 °C in the arc cavity, down to the weld pool liquidus temperare at the slag-weld pool interface.

Assessing Groundwater Potential in the Ziway Lake Watershed Using Geographical Information System, Analytic Hierarchy Process, and Drinking Water Quality Index

Global Challenges, Volume 9, Issue 6, June 2025.
This study identifies groundwater potential zones in Ethiopia’s Ziway Lake watershed using GIS and the SWAT model. Over half the area shows moderate to very high potential. Nearly 40% of high‐potential zones also have good to excellent water quality. The results offer a practical tool for sustainable groundwater management, with potential application ...

Waste-based consumable for hardfacing by welding: a look from the Circular Economy

Dyna
In the present work, the obtaining of a consumable for the restore parts by welding from the perspective of the circular economy is addressed, using industrial solid residuals (slag from steel production, graphite from fragments of electrodes of arc ...

Fracture and Damage Analysis of Cement‐Stabilized Fine and Coarse Grain Soils Under Static and Cyclic Loading Using Chevron‐Notched SCB Specimen

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 6, Page 2708-2724, June 2025.
ABSTRACT Fracture toughness and cohesive fracturing properties of two classes of sandy‐clay soils, (A) with fine and (B) coarse grains and stabilized with low (2%) and high (10%) cement (as soil stabilizer), were investigated using a chevron‐notched semicircular bend (CN‐SCB) sample under static and cyclic loads.

Use of Frit‐Disc Crucible Sets to Make Solution Growth More Quantitative and Versatile

Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 7, May 12, 2025.
The recent availability of step‐edge, frit‐disc crucible sets (generally sold as Canfield Crucible Sets or CCS) has led to multiple innovations associated with the group's use of solution growth. The use of CCS allows for the clean separation of liquid from solid phases during the growth process.
