Polymerization Via a Metal Centered Catalyst from Nanocellulose
High-density polyethylene composites are now able to go beyond previously realized storage moduli at 6-7% v/v loading using cellulose nanocrystals (CNC)s as the filler material. Using a custom catalyst, polymerization is carried out directly from the surfaces of the CNCs in a heterogeneous (slurry) fashion. Mechanical testing showed that this...

Identification, Modeling, and Filtering of the Quantization Error in Encoder Equivalent Output
Encoder equivalent output is widely used in modern industrial drives equipped with tools for improving the encoder resolution. A standard application for this output is electronic gearing for controlling slave amplifiers via the encoder equivalent output of a master drive. If left uncorrected, this noise would report unreal noise to the user, or lead...
