Effect of graphene nanosheets on interlaminar mechanical properties of carbon fiber reinforced metal laminates

open access: yesXibei Gongye Daxue Xuebao, 2022
Aiming at the problem of weak bond strength between CARALL metal/resin/fiber layers, this paper proposes a new preparation method to improve the bond strength between CARALL layers. In this method, Graphene platelets (GnPs) with different mass fractions (

The strengthening mechanism of a magnesia core ceramic [PDF]

open access: yesDental Materials, 1993
A high-expansion core material containing magnesia and forsterite may be used to make all-ceramic dental crowns with porcelain-fused-to-metal body porcelains. The purpose of this study was to investigate the strengthening mechanism for the magnesia core material.

Effect of aging temperatures on the microstructural stability and mechanical properties of Super304H steel

open access: yesJournal of Materials Research and Technology
Aging tests at 650 °C and 700 °C for up to 5000 h were performed on Super304H steel tubes. The microstructural evolution during aging was observed by optical microscopy (OM) and scanning electron microscopy (SEM).

Strengthening and mechanical stability mechanisms in nanostructured bainite [PDF]

open access: yesJournal of Materials Science, 2013
Understanding the main relationships between the microstructure parameters controlling the strength and ductility of low temperature bainitic microstructures is of considerable importance for further development of these grades. Although the microstructure essentially consists of solely two phases, bainitic ferrite and retained austenite, the ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
