Power interactions of scroll compressor elements
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The subject of our research is a scroll compressor. With its large number of advantages over reciprocating compressors in the form of overall, mass and production characteristics, they have their own difficulties associated with the theory of stability of a movable scroll during the operation process.

Shapeshifting Nanocatalyst for CO2 Conversion
Advanced Materials, Volume 38, Issue 2, 8 January 2026.A multi‐modal in situ characterization of Ag‐Cu nanoparticles during CO2 photoreduction sheds light on dynamic transformations occurring during reaction. The Cu(core)‐Ag(shell) nanoparticles present the Ag replacement by Cu atoms. Ag is trapped at the subsurface forming a Ag‐Cu‐O phase, and the nanoparticle spreads over the substrate.

R32 Scroll Compressors Technology
, 2012 The purpose of the work is to describe technology used to design a scroll compressor with R32 refrigerant. Study what are the main differences and their implications compared to R410A refrigerant scroll compressors. And also study from mechanical scroll compressor design point of view up to its system integration, what are the main design changes taken

Refrigerant R32 as lower GWP working fluid in residential air conditioning systems in Europe and the USA [PDF]
, 2017 Because air conditioning and heat pump systems contribute greatly to greenhouse gas emissions, equipment with both lower global warming potential (GWP) working fluids and a higher level of performance should be used.
