Highly hydrogen permeable Nb-Ti-Co hypereutectic alloys containing much primary bcc-(Nb, Ti) phase [PDF]

, 2012
In order to develop alloys combing high hydrogen permeability with large resistance to the hydrogen embrittlement, microstructures and hydrogen permeability (Phi) have been investigated for the as-cast alloys on the straight line connecting the ...

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

FEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Directed evolution of enzymes at the crossroads of tradition and innovation

FEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Microstructure, mechanical properties, and corrosion behavior of Zn-x wt.% Ti (x = 0, 0.3 and 1) alloys for biomedical applications

Journal of Materials Research and Technology
Zn-x wt.% Ti (x = 0, 0.3, and 1) alloys were developed using vacuum induction melting. The alloys were characterized using X-ray diffraction (XRD), optical microscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and ...

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

FEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Additive manufacturing of dense components in beta‑titanium alloys with crystallographic texture from a mixture of pure metallic element powders

Materials & Design, 2019
The fabrication of dense components composed of Ti-based alloys, i.e., Ti-X (X = Cr, Nb, Mo, Ta) alloys, from a mixture of pure elemental powders was achieved using selective laser melting (SLM) process.

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Influence of Yttrium on the Thermal Stability of Ti-Al-N Thin Films [PDF]

, 2010
Ti(1-x)Al(x)N coated tools are commonly used in high-speed machining, where the cutting edge of an end-mill or insert is exposed to temperatures up to 1100 degrees C.

Bone Compatibility of Experimental Ti–Ag and Ti–Cu Alloy Dental Implants in a Beagle Dog Model

Journal of Functional Biomaterials
Titanium–silver (Ti–Ag) and titanium–copper (Ti–Cu) alloys have been developed to improve the mechanical properties and machinability of titanium (Ti) for dental applications while maintaining corrosion resistance comparable to that of pure Ti.

Effect of composition on the structure and properties of Ti-Co-Cr alloys [PDF]

Metalurgija, 2010
The present work is a study of six as-cast Ti-Co-Cr alloys in the Ti-rich region with the purpose of examining the possibility of obtaining a new β-type Ti-alloys.
