Furfuryl alcohol (FA) is a biobased monomer derived from lignocellulosic biomass. The present work describes its polymerization in the presence of protic polar solvents, i.e., water or isopropyl alcohol (IPA), using maleic anhydride (MA) as an acidic initiator. The polymerization was followed from the liquid to the rubbery state by combining DSC and DMA data. In the …

A commonly used definition of polymer is a material that is composed of many monomers (from 10s to 1000s) all linked together to form chains. A monomer can be composed of one to many atoms which form the base unit which is repeated to form a polymer, as represented in the figure below. Poly means many; mer means to repeat.

Basics of Density Density measures the mass per unit volume.It is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm 3. The density of a plastic sample may change due to change in crystallinity, loss of plasticizers, absorption of solvent, etc. It is important to note that density varies with temperature. ...

The FA composition of adzuki bean lipids was linoleic, palmitic, and linolenic acids representing 45%, 25%, and 21%, respectively, of the total lipid content (Yoshida et al., 2008). The lipid contents of seeds of eight Vicia species collected in Turkey varied between 2.5% and 3.9%, with palmitic (7–23%) and stearic (15–35%) acids as the ...
The EJ201 and EJ202 engines had an aluminium alloy cylinder head with cross-flow cooling. Unlike the EJ20 engine, the intake ports for the EJ201 and EJ202 engines created a 'tumble swirl' motion for air as it entered the cylinder for better mixing of the air and fuel for more uniform flame travel and faster combustion.
