Abstract: A method includes accessing one or more models of battery cathode synthesis, battery cell prototyping, battery cell testing, or a combination thereof. The method also includes applying the one or more models for controlling one or more steps in a battery production workflow.

Abstract: Disclosed are a compressor and an air conditioner having same. The compressor includes: a first-stage cylinder, including a first-stage compression chamber; and a second-stage cylinder, including a second-stage compression chamber and a gas storage chamber. Refrigerant flowing out of the first-stage compression chamber flows through the storage chamber and enters into the second-stage compression chamber, and a flow area of the gas storage chamber is larger than an area of a gas outlet of the first-stage compression chamber. The compressor effectively solves problems that power consumption of the compressor is increased and performance is reduced due to large resistance loss in the cylinder of the compressor.

Abstract: A solid-state PEC includes mixed ionic and electronic conducting oxides that allow it to operate at temperatures significantly above ambient utilizing both the light and thermal energy available from concentrated sunlight to dissociate water vapor. The solid-state PEC has a semiconductor light absorber coated with a thin MIEC oxide for improved catalytic activity, electrochemical stability and ionic conduction, which is located between the gas phase and the semiconductor light absorber. As a result, the MIEC oxide provides a facile path for minority carriers to reach the water vapor as well as a path for the ionic carriers to reach the solid electrolyte. Elevated temperature operation allows reasonable band misalignments at the interfaces to be overcome, reduces the required overpotential, and facilitates rapid product diffusion away from the surface.

Abstract: Methods and systems for suppressing coking in dehydration reactions catalyzed by solid acids. Dehydration reactions catalyzed by one or more solid acid catalysts can be performed in the presence of a super critical carbon dioxide medium which prevents or minimizes coking of the solid acid catalysts. Methods and systems are provided for producing glycerol products, such as acrolein, acrylic acid, acetol, by performing a dehydration reaction of glycerol using one or more solid acid catalysts in the presence of a super critical carbon dioxide reaction medium. Such methods and systems can be nm for extended periods of time, or continuously, due to catalyst regeneration and/or recycling. Such methods and systems are configured to produce glycerol products from crude glycerol feedstock with minimal pretreatment.
