High-Energy Shape Memory Polymer Could Help Robots Flex Their Muscles
When stretched or deformed, shape memory polymers return to their original shapes after heat or light is applied. These materials show great promise for soft robotics, smart biomedical devices and…
Nonisothermal Reactors
The Nature of the Problem Although isothermal conditions are most useful for the measurement of kinetic data, real reactor operation is nonnally nonisothennal. Within the limits of heat exchange, the…
ADIABATIC REACTOR DESIGN
Most of chemical reactions encountered in inorganic or organic chemistry involve either release of heat or supply of heat to the reactor where the chemical reaction is in progress. One…

Types of Multiple Reactions
Use molar flow rates and concentrations; DO NOT use conversion!There are 4 classes of Multiple Reactions.1. Parallel Reactions2. Series Reactions3. Complex Reactions: Series and Parallel aspects combined4. Independent ReactionsIndependent reactions…
Factors that Affect the Rate of Reactions
Reaction kinetics is the study of the rate of chemical reactions, and reaction rates can vary greatly over a large range of time scales. Some reactions can proceed at explosively fast…
Consecutive or Sequential Reactions
This reaction is defined as that reaction which proceeds from reactants to final products through one or more intermediate stages. The overall reaction is a result of several successive or…
