Current-carrying friction of Ag coatings by additive manufacturing: uncovering the role of electric current

open access: yesMaterials Research Letters
Ag coatings by additive manufacturing are a representative high-performance electrical contact materials. Here, an appropriate current of 2 A is introduced during the friction process to optimize the current-carrying friction behavior and anti-wear ...

Comparative Braking Performance Evaluation of a Commercial and Non-asbestos, Cu-free, Carbonized Friction Composites

open access: yesMedžiagotyra, 2021
Carbonization treatment contributes to improvement of tribological properties of friction composites. Pure Non-asbestos organic (NAO) friction raw materials were selected, friction composite specimens had been made using a new mixing process and ...

Study of Friction and Wear Behavior of Graphene-Reinforced AA7075 Nanocomposites by Machine Learning

open access: yesJournal of nanomaterials, 2023
In this research, the friction and wear of AA7075 nanocomposites reinforced with graphene and graphite were studied. Graphene’s inclusion dramatically enhanced the material’s mechanical characteristics, friction, and wear resistance.

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

open access: yesFEBS 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.

Thermodynamics and kinetics of boundary friction [PDF]

open access: yes, 2011
A deterministic theory describing the behavior of an ultrathin lubricant film between two atomically-smooth solid surfaces is proposed. For the description of lubricant state the parameter of excess volume arising due to chaotization of solid medium ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Cross Scale Tribological Behavior of Textured High-Entropy Alloy Coatings

open access: yesLubricants
This paper presents a cross-scale model for predicting the tribological behavior of textured coatings made of high-entropy alloys. The research methodology includes molecular dynamic modeling, a modified fractal surface model, and the Green’s method with
