Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Metal ceramic wear mechanisms [PDF]

open access: yes, 1990
Sliding wear of metal-on-ceramic, ceramic-on-metal, and ceramic-on-ceramic have been investigated using a tri-pin-on-disc machine. A technique has been developed for thin foil preparation for transmission electron microscopic examination perpendicular ...

Highly stable graphene-oxide-based membranes with superior permeability

open access: yesNature Communications, 2018
Graphene oxide membranes show great potential for water filtering, but improving their performance and stability remains difficult. Here, the authors use theanine amino acid and tannic acid to reduce and cross-link graphene oxide membranes with ...

Active oxygen species mediate the iron-promoting electrocatalysis of oxygen evolution reaction on metal oxyhydroxides

open access: yesNature Communications, 2023
Iron is an extraordinary promoter to impose nickel/cobalt (hydr)oxides as the most active oxygen evolution reaction catalysts, whereas the synergistic effect is actively debated. Here, we unveil that active oxygen species mediate a strong electrochemical

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Metal strippers: their science and technology [PDF]

open access: yesTransactions of the IMF, 2007
AbstractMetal strippers in the electroplating industry are often considered to be necessary evils: they add additional processing and cost to correct earlier processing deficiencies yet enable expensive component substrates to be re-coated for prime engineering usage.

AscF in the mycobacterial CIII–CIV supercomplex lacks metal and nucleotide binding but links malate oxidation to respiration

open access: yesFEBS Letters, EarlyView.
The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...

Synthesis of Transition Metal Dichalcogenides [PDF]

open access: yes, 2017
Novel properties and new phenomena that arise from two-dimensional (2D) materials have stimulated huge research interest recently. Among the 2D material family, semiconducting transition metal dichalcogenides (TMDCs) with an intrinsic band gap are ...
