Preferential weld corrosion of X65 pipeline steel in flowing brines containing carbon dioxide [PDF]

, 2011
The aim of this research was to investigate the cause of the severe localised corrosion that sometimes occurs at welds in carbon steel pipelines carrying hydrocarbons and inhibited brines saturated with carbon dioxide.

Reconstructing enzyme evolution by protein engineering

FEBS 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 ...

Argon plasma treatment techniques on steel and effects on diamond-like carbon structure and delamination [PDF]

, 2011
We demonstrate alteration in diamond-like carbon (DLC) film structure, chemistry and adhesion on steel, related to variation in the argon plasma pretreatment stage of plasma enhanced chemical vapour deposition.

Achieving exceptional strength-low temperature toughness synergy in the microalloyed medium carbon steel via layered heterogeneous structure

Materials & Design
The further advancement of microalloyed medium carbon steels is often limited by low-temperature toughness instability. A microalloyed medium carbon steel with both strength and low-temperature toughness was produced through a warm rolling and short-time

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Microstructure and impact toughness evolution in high-strength anchor chain steel: A Jominy test-based investigation

Materials & Design
Ensuring the impact toughness of anchor chains remains challenging due to inhomogeneities in microstructure and mechanical properties induced by variations in cooling rates during quenching.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Effect of interlamellar spacing on the elastoplastic behavior of C70 pearlitic steel: Experimental results and self-consistent modeling [PDF]

, 2014
The effect of pearlite microstructure characteristics on strength and deformation of C70 pearlitic steel was investigated. Tensile tests under X-ray diffraction coupled with self-consistent model have been used to identify the role of interlamellar ...

Effect of trace Nb on phase transformation and precipitation dynamics of 1600 MPa high-carbon pearlite wire rod produced by online isothermal treatment

Materials & Design
As a raw material for large building structural components, such as bridge cables and prestressed steel strands, high-carbon wire rods face increasingly prominent issues of insufficient plasticity and Ti(C, N) inclusions as their strength increases.

Obtaining Excellent Mechanical Properties in an Ultrahigh-Strength Stainless Bearing Steel via Solution Treatment

Metals, 2023
A novel versatile ultrahigh-strength stainless bearing steel was prepared by first solution treating the steel at temperatures between 1000 °C and 1100 °C for 1 h, followed by performing cryogenic treatment at −73 °C for 2 h, and tempering at 500 °C for ...
