What is non-Newtonian flow.

400

An organometallic chemical reaction in which carbon alkyl, allyl, vinyl, or aryl magnesium halides are added to the carbonyl groups of either an aldehyde or ketone.

What is the Grignard reaction?

400

This diagram plots the total heat against entropy, describing the enthalpy of a thermodynamic system.

800

This added substance can cover up catalytic surface to actively remove or prevent production of a mat of coke during carbon catalysis.

What are promoters?

800

This instrument measured the flow rate of a fluid in a closed tube.

What is a rotameter?

800

Fluid motion characterized by chaotic changes in pressure and flow velocity.

What is turbulent flow?

800

Physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field and respond by producing an electromagnetic signal.

800

Graphical representation of the Michaelis–Menten equation of enzyme kinetics.

What is the Lineweaver-Burk Plot?

1200

A parameter used to quantify the activity of a catalyst, also known as the number of molecules reacting per active site per second at the conditions of the experiment.

What is the turnover frequency?

1200

Removes low-boiling organic chemicals, usually solvents, from a mixture of compounds.

What is a rotevap?

1200

A type of fluid flow where advective inertial forces are small compared with viscous forces.

What is Stokes (or creeping) flow?

1200

The enthalpy change of any amount of substance when it melts.

What is the latent heat of fusion?

1200

Dimensionless ratio of a characteristic liquid residence time to the reaction time.

What is the Damkohler number?

1600

This mechanism details how two molecules adsorb on neighboring sites and the adsorbed molecules undergo a bimolecular reaction.

What is the Langmuir-Hinselwood mechanism?

1600

Analytical instrument designed to control the working electrode's potential in a multiple-electrode electrochemical cell

1600

The flow is characterized by Reynolds numbers less than 2000.

What is laminar flow?

1600

Cellular process that harnesses the reduction of oxygen to generate high-energy phosphate bonds in the form of adenosine triphosphate.

What is oxidative phosphorylation?

1600

Used to determine the temperature driving force for heat transfer in flow systems, most notably in heat exchangers

Mechanical equipment used for reducing material to extremely small thicknesses

What is a Four Roll Mill?

2000

The flow of a viscous fluid in the space between two surfaces, one of which is moving tangentially relative to the other.

What is Couette's Flow?

2000

Chemical reaction between a conjugated diene and a substituted alkene, commonly termed the dienophile, to form a substituted cyclohexene derivative.
