Stripe melting and quantum criticality in correlated metals

open access: yes, 2012
We study theoretically quantum melting transitions of stripe order in a metallic environment, and the associated reconstruction of the electronic Fermi surface.

Deformation mechanisms in nanotwinned metal nanopillars [PDF]

open access: yes, 2012
Nanotwinned metals are attractive in many applications because they simultaneously demonstrate high strength and high ductility, characteristics that are usually thought to be mutually exclusive.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

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

open access: yesJournal 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

Acid-Assisted Separation of Cathodic Material from Spent Electric Vehicle Batteries for Recycling

open access: yesMetals, 2023
The recycling of lithium-ion batteries presents challenges due to the complex composition of waste streams generated by current processes. Achieving higher purity levels, particularly in the reclamation of aluminium metal and transition metal black mass,

Coexistence of orbital and quantum critical magnetoresistance in FeSe$_{1-x}$S$_{x}$

open access: yes, 2019
The recent discovery of a non-magnetic nematic quantum critical point (QCP) in the iron chalcogenide family FeSe$_{1-x}$S$_{x}$ has raised the prospect of investigating, in isolation, the role of nematicity on the electronic properties of correlated ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Ultrafast recovery of Zn from waste galvanized iron sheet by ultrasound-assisted acid pickling and ion flotation techniques

open access: yesUltrasonics Sonochemistry
High-efficiency dezincification from waste galvanized iron sheets is crucial for resource recovery and environmental protection. In this work, ultrasound-assisted acid pickling and ion flotation techniques were combined to intensify the Zn extraction and

Challenging the Need for Deep Seabed Mining From the Perspective of Metal Demand, Biodiversity, Ecosystems Services, and Benefit Sharing

open access: yesFrontiers in Marine Science, 2021
The extraction of minerals from the seabed of the deep oceans is of increasing interest to investors, mining companies and some coastal states. To date, no commercial-scale deep seabed mining has taken place but there is considerable pressure for ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
