What is the meaning of crosslinking as it relates to polymers? a) In terms of tensile strength, melting point etc. how does a crosslinked polymer compare with a non-crosslinked polymer? b) Draw a simple schematic diagram of linear polyethylene and crosslinked polyethylene (chemical structure of ethylene is CH2 = CH2).
g. Draw a schematic diagram of the structure and explain how it works. Electron spectroscopy for chemical analysis (ESCA) Thank you so much.
Draw a chain of HDPE (linear polyethylene) & LDPE (branched polyethylene).
Draw the schematic diagram of metalorganic chemical vapor deposition (MOCVD) machine and explain MOCVD growth mechanism in detail.
The linear ethylene molecule CH2=CH2 can be considered as a molecular box with length defined by the C=C length: 0.154 nm. How many declocalized electrons are confined in this molecular box? Use a drawing, sketch , etc. to show how you decided. Draw the energy level diagram of these electrons states in ethylene and show the electrons that occupy them.

Draw the following schematic circuit diagram and label them accordingly: (a) Draw the schematic for a circuit in which a 10 V battery, a 100 resistor, and a 220 resistor are all in series with one another. Determine the voltage across each resistor and the current owing through each resistor. (b) Draw the schematic for a circuit in which a 10 V battery, a 100 resistor, and a 220 resistor are all in parallel with one another. Determine the voltage...
