Abstract: Systems and methods for producing a covalent organic framework including providing a first monomer to a first zone in a furnace, a second monomer to a second zone in the furnace, and a substrate to a third zone in the furnace, where the third zone is located downstream from the first zone and the second zone. Systems and methods also include heating the furnace to a achieve temperature profile having a range of temperatures where the range of temperatures vaporizes the first monomer the second monomer. Systems and methods further include absorbing, onto the substrate, the first vaporized monomer and the second vaporized monomer to produce a covalent organic framework (COF). Articles produced by systems and methods include a film of a covalent organic framework (COF). The COF is a reaction product of a first monomer and a second monomer, and the COF is arranged in a two-dimensional crystalline lattice.

Abstract: An HVAC system for a comfort zone includes a compressor, temperature sensor and controller. The controller is configured to receive a starting temperature from the temperature sensor, receive a desired temperature, and receive a desired time for the comfort zone to reach the desired temperature. The controller is further configured to determine a starting time to adjust cooling the comfort zone, the starting time determined based at least on the desired time, the desired temperature, the starting temperature, and a most-energy-efficient operating speed of the compressor. Once the starting time has been reached, the controller is further configured to communicate a command to the HVAC system to operate the compressor at the most-energy-efficient operating speed.

A display case can be provided with one or more heater circuits and one or more sensors communicably coupled thereto. The sensor can sense ambient humidity levels, ambient temperature levels, and surface temperature levels.
