In vitro re-hardening of artificial enamel caries lesions using enamel matrix proteins or self-assembling peptides

open access: yesJournal of Applied Oral Science, 2016
Objectives To assess the re-hardening potential of enamel matrix derivatives (EMD) and self-assembling peptides in vitro, hypothesizing that these materials may increase the mineralization of artificial carious lesions and improve hardness profiles ...

HgZnTe-based detectors for LWIR NASA applications [PDF]

open access: yes
The initial goal was to grow and characterize HgZnTe and determine if it indeed had the advantageous properties that were predicted. Researchers grew both bulk and liquid phase epitaxial HgZnTe. It was determined that HgZnTe had the following properties:

Tribological behaviour of alumina-titania nanostructured coatings produced by air plasma spray technique [PDF]

open access: yes, 2016
Nanostructured Al2O3-TiO2 wear resistant coatings were produced by air plasma spray from plasma-densified agglomerated nano-powders. Conventional Al2O3-TiO2 coatings were also deposited for direct comparison of tribological performance.

Effects of applied pressure on hot-pressing of Beta-SiC [PDF]

open access: yes
The effects of applied pressure on the densification during hot pressing of beta-SiC compacts were investigated. Beta-SiC powder is Starck made and has the average particle size of about 0.7 micrometer.
