A novel carbon fiber precursor was prepared from lignosulfonate (LS) with acrylonitrile (AN)
via a two-step process consisting of esterification and free radical copolymerization. The LS–…

Flexible polypyrrole/graphene oxide (GO) nanocomposite paper was prepared via a facile
and one-step chemical oxidation polymerization method. The morphology and microstructure …

Lignin, as an abundant carbon-rich renewable resource, is a promising precursor for carbon
fibers. However, due to the poor spinnability of lignin, a great challenge comes from the …

This paper establishes linear state equation and measurement equation based on error
quaternion, designs the multiple-sensor attitude determination model, directly applies the …

To meet the requirement of the satellite attitude and orbit control system (AOCS) could
recover control in abnormal conditions, A reconfigurable control system using variable-structure …

This paper proposes a new algorithm for joint attitude estimation based on satellite-borne
antenna information, which extracts the information used to estimate the satellite attitude from …

The age-related cognitive decline of normal aging is exacerbated in neurodegenerative
diseases including Alzheimer’s disease (AD). However, it remains unclear whether age-related …

When an infrared imaging air-to-air missile attacks a fighter target in head-on condition or
tail attack condition, due to slow separation between the artificial infrared decoys and the …
