Effect of pulsed magnetic field pre-treatment of AISI 52100 steel on the coefficient of sliding friction and wear in pin-on-disk tests [PDF]

open access: yes, 2014
Disc specimens manufactured from commercial bearing rollers (AISI 52100 steel, 62–63 HRC) in initial state and after pre-treatment by pulsed magnetic field (PMF) with a magnetic field strength of 1–7 MA/m were tested with sunflower oil using pin-on-disk ...

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

open access: yesAdvanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

Changes in Physical Parameters of CO2 Containing Impurities in the Exhaust Gas of the Purification Plant and Selection of Equations of State

open access: yesFluids
CO2 transport is a crucial part of CCUS. Nonetheless, due to the physical property differences between CO2 and natural gas and oil, CO2 pipeline transport is distinct from natural gas and oil transport. Gaseous CO2 transportation has become the preferred

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...

Prediction method of pore pressure of carbonate rock and shale considering regional differences - a case study of the Luzhou block in southern Sichuan

open access: yesJournal of Petroleum Exploration and Production Technology
Luzhou, in the southern Sichuan Basin, is one of China’s major shale-gas production areas; however, its extensive Permian carbonate formations frequently exhibit gas-logging anomalies and minor gas intrusion during drilling—both in carbonate and shale ...

Transfer of Energy and Momentum Between Magnetoactive Surface Microstructure and a Solid Object

open access: yesAdvanced Engineering Materials, EarlyView.
We demonstrate that magnetoactive multilamellar arrays subjected to a rotating magnetic field can function as platforms for controlled transport of physical objects. Through systematic experimental investigation, we elucidate the underlying physical mechanisms determining the upper limit of the achievable transportation speed in such magnetic “conveyor‐
