Grinding and Concentration Technology of Critical Metals

Metals, 2022
The production and supply of raw materials in a global market are not without risks, and both the recent COVID-19 pandemic and the current one (Russia–Ukrania conflict) raised public awareness about the importance of multiple value chains [...]

Quantum criticality in heavy-fermion metals [PDF]

Nature Physics, 2008
Quantum criticality describes the collective fluctuations of matter undergoing a second-order phase transition at zero temperature. Heavy fermion metals have in recent years emerged as prototypical systems to study quantum critical points. There have been considerable efforts, both experimental and theoretical, which use these magnetic systems to ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Anthropogenic heavy metals in organic forest soils [PDF]

, 2006
The continuous heavy metal accumulation in organic topsoils in forests will pose problems for soil microbial health for many years to come. The primary objective of this thesis was to investigate heavy metal pollution in forest soils and its effects on ...

Observation of a critical charge mode in a strange metal

Science, 2023
Understanding the strange metallic behavior that develops at the brink of localization in quantum materials requires probing the underlying electronic charge dynamics. Using synchrotron radiation–based Mössbauer spectroscopy, we studied the charge fluctuations of the strange metal phase of β-YbAlB 4 as a function of

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Precipitation–Flotation Process for Molybdenum and Uranium Separation from Wastewater

Metals
The mining of molybdenum and uranium ores inevitably results in the generation of large volumes of wastewater containing low concentrations of metals, which poses significant threats to the environment. This study presents a novel precipitation–flotation

Metal-nonmetal transition and the second critical point in expanded metals [PDF]

EPL (Europhysics Letters), 2013
Based on the non-relativistic Coulomb model within which the matter is a system of interacting electrons and nuclei, using the quantum field theory and linear response theory methods, opportunity for the existence of the second critical point in expanded metals, which is directly related to the metal--nonmetal transition, predicted by Landau and ...

Versatile vector tools for efficient protein screening across multiple expression systems

FEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Sintering behavior and densification mechanisms of ultrafine molybdenum powders under varying compaction and sintering conditions

Journal of Materials Research and Technology
The sintering behavior of ultrafine molybdenum powders with a particle size of approximately 1 μm was systematically investigated. The impact of cold isostatic pressing (CIP) and sintering parameters on the densification of molybdenum was investigated. A
