Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Ru–Mo solid–solution catalyst for hydrogen evolution in alkaline electrolyte

Nano Research
Hydrogen energy carrier produced by water electrolysis in alkaline electrolytes is rather meaningful and significant for global sustainability imperatives, while the high-pH condition usually leads to a poor reversibility of proton adsorption and ...

Comparison of the effect of different infusion rates of sufentanil on surgical stress index during cranial pinning in children under general anaesthesia: a randomized controlled study

BMC Anesthesiology, 2017
Background Surgical stress index (SSI) is an established indicator for intraoperative nociception. Opioids are used to block stimulus of cranial pinning in neurosurgery.

Flux expulsion in niobium superconducting radio-frequency cavities of different purity and essential contributions to the flux sensitivity

Physical Review Accelerators and Beams, 2020
Magnetic flux trapped during the cooldown of superconducting radio-frequency cavities through the transition temperature due to incomplete Meissner state is known to be a significant source of radio-frequency losses.

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring

Advanced Engineering Materials, EarlyView.
Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

Flux pinning and peak effect in Y-123 superconductor [PDF]

, 2001
It is known that the peak effect in Y-123 superconductors is caused by oxygen deficient regions with lower Tc. In order to study the flux pinning mechanism of these defects, the effect of addition of 211 particles on the peak effect was measured.

Solute Segregation and Pinning Effect on Lateral Twin Boundary in Magnesium

Metals
Deformation twinning creates a three-dimensional twin domain via the migration of forward, normal and lateral twin boundaries (TBs) with respect to twin shear direction, normal to twin plane and twin lateral direction.

Flux-pinning behaviors and mechanism according to dopant level in (Fe, Ti) particle-doped $$\text {MgB}_2$$ MgB 2 superconductor

Scientific Reports, 2021
We have studied flux-pinning effects of $$\text {MgB}_2$$ MgB 2 superconductor by doping (Fe, Ti) particles of which radius is 163 nm on average. 5 wt.% (Fe, Ti) doped $$\text {MgB}_2$$ MgB 2 among the specimens showed the best field dependence of ...
