Micromorphology, Microstructure, and Wear Behavior of AISI 1045 Steels Irregular Texture Fabricated by Ultrasonic Strengthening Grinding Process

open access: yesMetals, 2022
In this study, the tribological properties of three AISI 1045 steel samples were investigated. Two samples were treated with ultrasonic shot peening (USP) and ultrasonic strengthening grinding process (USGP), respectively, while the other one was only ...

Teeth grinding [PDF]

open access: yesDown Syndrome Research and Practice, 2007
Teeth grinding turns out to be no more common in children with Down syndrome than it is in other children and it reduces with age. These are reassuring findings as teeth grinding can be quite an annoying problem at home and at school.

How to combine a hydrophobic matrix and a hydrophilic filler without adding a compatibilizer – Co-grinding enhances use properties of renewable PLA-starch composites [PDF]

open access: yes, 2012
In order to avoid the use of compatibilizers or plasticizers, co-grinding was performed to produce PLA – starch composite materials. Fragmentation and agglomeration phenomena were analysed to propose a production mechanism.
