Effect of Base Oil Type in Grease Composition on the Lubricating Film Formation in EHD Contacts

open access: yesLubricants, 2018
The service life of rolling bearings is significantly affected by the film formation in elastohydrodynamic (EHD) contacts, which depends on the operating conditions, like rotational speed or temperature.

Inflation and unemployment revisited: grease vs. sand [PDF]

open access: yes, 1998
As inflation rates in the United States decline, analysts are asking if there are economic reasons to hold the rates at levels above zero. Previous studies of whether inflation "greases the wheels" of the labor market ignore inflation's potential for ...

Decoupling Thermodynamic and Kinetic Moisture Instability Reveals a Critical Humidity Threshold for Sodium Thiophosphate Solid Electrolyte

open access: yesAdvanced Energy Materials, EarlyView.
A quantitative exposure‐heat treatment framework identifies a critical humidity threshold (15%RH) and heat treatment temperature (80°C) that governs the recoverability of air‐exposed Na3PS4, revealing the decoupled thermodynamic and kinetic contributions to its moisture stability.

Evaluation and Optimization of COD Removal Performance for a Domestic Wastewater Treatment Plant by Response Surface Methodology: The Case of Van Muradiye

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, the performance of the Van Muradiye Domestic Wastewater Treatment Plant was evaluated with Response Surface Methodology (RSM). The effects of pH, conductivity, dissolved oxygen (DO), and suspended solids (SS) on the chemical oxygen demand (COD) removal efficiency were evaluated using samples collected from the plant's inlet and ...

Effect of UHMWPE Incorporation on the Tribological Performance of Carbon fiber‐Reinforced PEEK Nanocomposites

open access: yesJournal of Applied Polymer Science, EarlyView.
UHMWPE provides interfacial lubrication, improving tribological performance of PEEK‐based sliding bearing bushings. ABSTRACT Ultra‐high molecular weight polyethylene (UHMWPE) was incorporated into a PEEK‐based hybrid material as a lubrication additive to improve the friction and wear performance of the composite due to its superior lubricity ...

Pure Inverse Spin Hall Effect in Ferromagnetic Ni80Fe20/Y3Fe5O12 (YIG) Heterostructures via the Longitudinal Spin Seebeck Effect

open access: yesAdvanced Physics Research, EarlyView.
A pure inverse spin Hall effect (ISHE) is demonstrated in ferromagnetic Ni₈₀Fe2₀/YIG heterostructures via the longitudinal spin Seebeck effect. By employing symmetry‐controlled geometries and reference samples, anomalous Nernst contributions are quantitatively eliminated, revealing intrinsic spin–charge conversion in Ni₈₀Fe2₀.

Designing and evaluating a neuroanatomy learning experience using multiple external representations

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Neuroanatomy is challenging, requiring multiple external representations (MER) for comprehension. While studies have examined individual representations of neuroanatomy, a gap remains in understanding how students link across MER, especially between technology‐generated representations with everyday experiences.

Dissecting the dissection laboratory: Elements for designing a human anatomy laboratory

open access: yesAnatomical Sciences Education, EarlyView.
Abstract The human anatomy dissection laboratory is a critical component of anatomical and medical education. Development, maintenance, and stocking of these laboratory spaces have unique demands, with all of the challenges in running a laboratory with Biosafety Laboratory Level 2 (BSL‐2) classification, housing a large volume of tissues saturated with
