Bearing material [PDF]

open access: yes, 1976
A composite material is described which will provide low friction surfaces for materials in rolling or sliding contact and is self-lubricating and oxidation resistant up to and in excess of about 930 C.

The effect of pressure and temperature variations on the FEM prediction of deformation during extrusion [PDF]

open access: yes, 2005
The extrusion process is complex, involving interaction between the process variables and the material’s high temperature properties and is typically conducted at relatively high temperatures because the lower flow stress of the material permits larger ...

Three‐Dimensional Printed Microarchitected Hierarchically Porous Biodegradable PLA/S/CNT Nanocomposite Electrodes for High‐Performance Lithium–Sulfur Batteries

open access: yesAdvanced Materials Technologies, EarlyView.
Hierarchically microarchitected PLA/S/CNT cathodes are fabricated via scalable fused filament 3D printing as high‐sulfur‐loading hosts for rechargeable lithium–sulfur batteries. The assembled Li–S cells with sulfur loadings up to 17 mg cm−2 deliver an areal capacity of 9.2 mAh cm−2 and retain 96% of their discharge capacity after 100 charge–discharge ...

Revised Two-Stage Model of Preeclampsia Based on Autophagic Dysfunction: A Comprehensive Review

open access: yesBiomolecules
A revised two-stage model of preeclampsia is proposed, centering on an autophagy-dependent requirement for extravillous trophoblast entry into the proximal one-third of the myometrium.

Momentum-Dependent Mean Field Based Upon the Dirac-Brueckner Approach for Nuclear Matter

open access: yes, 1993
A momentum-dependent mean field potential, suitable for application in the transport-model description of nucleus-nucleus collisions, is derived in a microscopic way.

Simulation in the Call-by-Need Lambda-Calculus with Letrec, Case, Constructors, and Seq [PDF]

open access: yes, 2015
This paper shows equivalence of several versions of applicative similarity and contextual approximation, and hence also of applicative bisimilarity and contextual equivalence, in LR, the deterministic call-by-need lambda calculus with letrec extended by ...

Climate Action Impacts on Steelmaking Emissions of Persistent Organic Pollutants Highlight a Gap Between the Paris Agreement and the Stockholm Convention

open access: yesAdvanced Science, EarlyView.
Emissions of unintentionally produced persistent organic pollutants (UPOPs) and global warming are two major environmental challenges. But their governance has largely evolved in parallel, leaving the toxicity implications of climate‐driven industrial transitions poorly understood.

Inhibitory Effects of Eleutherococcus senticosus Extracts on Amyloid β(25-35)–Induced Neuritic Atrophy and Synaptic Loss

open access: yesJournal of Pharmacological Sciences, 2008
Neurons with atrophic neurites may remain alive and therefore may have the potential to regenerate even when neuronal death has occurred in some parts of the brain.

Microscopic Calculation of in-Medium Proton-Proton Cross Sections

open access: yes, 1993
We derive in-medium PROTON-PROTON cross sections in a microscopic model based upon the Bonn nucleon-nucleon potential and the Dirac-Brueckner approach for nuclear matter.
