Effect of nanostructuration on compressibility of cubic BN [PDF]

open access: yes, 2012
Compressibility of high-purity nanostructured cBN has been studied under quasi-hydrostatic conditions at 300 K up to 35 GPa using diamond anvil cell and angle-dispersive synchrotron X-ray powder diffraction.

Spark plasma sintering of cBN(core)/SiO2(shell) powder prepared by rotary chemical vapor deposition

open access: yesJournal of Asian Ceramic Societies, 2014
SiO2 nanolayer coated cubic boron nitride (cBN), cBN(core)/SiO2(shell) powder, was prepared by rotary chemical vapor deposition. The cBN/SiO2 powder was densified by spark plasma sintering at 1873 K for 0.3 ks. The hexagonal boron nitride (hBN) phase was

Columbianadin Suppresses Lipopolysaccharide (LPS)-Induced Inflammation and Apoptosis through the NOD1 Pathway

open access: yesMolecules, 2019
Columbianadin (CBN) is one of the main bioactive constituents isolated from the root of Angelica pubescens. Although the anti-inflammatory activity of CBN has been reported, the underpinning mechanism of this remains unclear.

Control of voluntary and optogenetically perturbed locomotion by spike rate and timing of neurons of the mouse cerebellar nuclei

open access: yeseLife, 2018
Neurons of the cerebellar nuclei (CbN), which generate cerebellar output, are inhibited by Purkinje cells. With extracellular recordings during voluntary locomotion in head-fixed mice, we tested how the rate and coherence of inhibition influence CbN cell
