The agglomeration, coalescence and sliding of nanoparticles, leading to the rapid sintering of zirconia nanoceramics.

Scientific reports

Kocjan A, Logar M, Shen Z.
PMID: 28566771
Sci Rep. 2017 May 31;7(1):2541. doi: 10.1038/s41598-017-02760-7.

Conventional sintering is a time- and energy-consuming process used for the densification of consolidated particles facilitated by atomic diffusion at high temperatures. Nanoparticles, with their increased surface free energy, can promote sintering; however, size reduction also promotes agglomeration, so...

SICOT J. 2016;2:24. doi: 10.1051/sicotj/2016016. Epub 2016 May 16.

INTRODUCTION: The purpose of the study is to compare the effects of genistein, estradiol, estradiol/progesterone combination on the bone mineral density and biomechanical properties of ovariectomized rats' bone.METHODS: 50 female adult Sprague-Dawley rats were divided into five groups. Bilaterally...

Prolonged receptor blockade by opioid receptor probes.

Pharmaceutical research

Koman A, Kolb VM, Terenius L.
PMID: 24271359
Pharm Res. 1986 Feb;3(1):56-60. doi: 10.1023/A:1016329000518.

Opioid receptor interactions of morphinan-type opioids derivatized at the C-6 carbon were investigated. The compounds, designed as probes for studying opioid receptors, were characterized with regard to affinity for the rat brain mu receptor by competition with tritium-labeled dihydromorphine...

BACKGROUND: Idiopathic granulomatous mastitis (IGM) is an uncommon chronic inflammatory disease of the breast with uncertain optimal treatment regimen. In this study, our purpose was to report our clinical experience with 74 IGM patients who were treated wide local...

The role of exchange-correlation functionals in the potential energy surface and dynamics of N(2) dissociation on W surfaces.

The Journal of chemical physics

Bocan GA, Díez Muiño R, Alducin M, Busnengo HF, Salin A.
PMID: 18433255
