Peanut Shell Derived Carbon Combined with Nano Cobalt: An Effective Flame Retardant for Epoxy Resin

open access: yesMolecules, 2021
Biomass-derived carbon has been recognised as a green, economic and promising flame retardant (FR) for polymer matrix. In this paper, it is considered that the two-dimensional (2D) structure of carbonised peanut shells (PS) can lead to a physical barrier

Parametric instability analysis of multi-segment conical shells under periodic spin speed

open access: yesResults in Physics
This study is the first to investigate the parametric instability of multi-segment conical shells (MSCSs) under periodic spin speed. The artificial spring simulates the general boundary constraints and the constraints between shell segments.

Comparison of cone and cone shell configuration for depth sensitive fluorescence measurements in turbid media [PDF]

open access: yesSPIE Proceedings, 2014
We have developed a novel cone shell illumination and detection configurations using combination of axicon lenses for depth sensitive fluorescence spectroscopy. The probe was demonstrated experimentally to be able to selectively detecting fluorescence from different depths from a two-layered turbid agar phantom.

Functional evidence for cone-specific connectivity in the human retina [PDF]

open access: yes, 2005
NoPhysiological studies of colour vision have not yet resolved the controversial issue of how chromatic opponency is constructed at a neuronal level. Two competing theories, the cone-selective hypothesis and the random-wiring hypothesis, are currently ...
