Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Dual laser-beam synchronous self-fusion welding of Ti–6Al–4V titanium alloys T-joints based on prefabricated welding materials

Journal of Materials Research and Technology, 2022
Aiming at the difficulty of feeding filler wire in the dual laser-beam synchronous welding (DLSW) of Ti–6Al–4V titanium alloys T-joints, the self-fusion DLSW process based on prefabricated welding materials on the stringer was developed.

Sealing is at the Origin of Rubber Slipping on Wet Roads

, 2004
Loss of braking power and rubber skidding on a wet road is still an open physics problem, since neither the hydrodynamical effects nor the loss of surface adhesion that are sometimes blamed really manage to explain the 20-30% observed loss of low speed ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Structural biology of ferritin nanocages

FEBS 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 ...

The effect of inclusions and pores on creep crack propagation of linear friction welded joints of GH4169 superalloy

Journal of Materials Research and Technology
Superalloy has become the key material in components of blisks for aero-engines produced by linear friction welding. However, during the long-term service of the blisks, stress rupture occurs on the blisk under long-term creep.

Verification of tribo-reduction of copper oxide in phenolic composite material through visualization of friction surface

Nihon Kikai Gakkai ronbunshu, 2018
The surface of phenolic composite material was continuously observed through borosilicate glass (BK7) during friction to verify the tribo-reduction of copper oxide (CuO) taking place at the interface. Two types of pad samples were slid against a rotating

Tribological and mechanical behaviours of resin‐based friction materials based on microcrack filling

Biosurface and Biotribology, 2023
To enhance the friction performance of resin‐based friction materials, five types of specimens with different polymer ether ketone (PEEK) contents were fabricated and their physiomechanical behaviours were tested and, their tribological properties were ...
