Performance of large-bore tapered-roller bearings under combined radial and thrust load at shaft speeds to 15,000 rpm [PDF]

The performance of 120.65-mm bore tapered roller bearings was investigated at shaft speeds up to 15,000 rpm. Temperature distribution and bearing heat generation were determined as a function of shaft speed, radial and thrust loads, lubricant flow rate ...

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Designing High‐Entropy Alloys With Low Stacking Fault Energy Through Interpretable Machine Learning

Materials Genome Engineering Advances, EarlyView.
In this study, we developed an interpretable machine learning (ML) ensemble framework and, by integrating the VEC criterion with the proposed machine learning scoring parameter in the alloy composition screening process, successfully designed multiple CoCrFeNiMn‐based HEAs with TWIP/TRIP effects and without the BCC phase.

Modeling Fiber Dispersion in a Single‐Screw Extruder for Long Fiber‐Reinforced Thermoplastics

Polymer Composites, EarlyView.
Fiber dispersion throughout the screw channel ABSTRACT Understanding the mechanics of fiber attrition during the plasticizing process is important in predicting the strength of long fiber‐reinforced thermoplastics (LFT) composites. Fiber dispersion has been found to impact fiber damage during processing and therefore final fiber length in the final ...

Topography‐Free Dual‐Lubricant Patterned Slippery Surfaces for Programmable Droplet Control and High‐Performance Water Harvesting

Small, EarlyView.
A patterned dual‐lubricant SLIPS creates interfacial energy asymmetry, guiding droplet migration without external actuation. Condensed droplets formed on the fluorinated‐oil‐infused regions migrate to the silicone‐oil‐infused domains, where rapid growth and coalescence occur.
