Back in 2020, when Apple introduced AirPods Max, some customers noticed that the headphones were facing condensation issues inside the ear cups. At the time, Apple never acknowledged that there was a ...
Formation of Nanoparticles in Gaseous Phase Reactions and Flame Synthesis in Microgravity Conditions
The inert gas condensation process is one of the established procedures for the production of nanopowders, e.g. for nanoporous metal powders. These metal powders are technically utilized for ...
In all Ugi reactions, the formerly divalent carbon of the isocyano group becomes tetravalent. This irreversible transformation explains the usefulness of Ugi reactions for synthetic purposes. Other ...
This study shows that the Thermafil technique provides better results than cold lateral condensation if a corono-apical tapered preparation is made. This technique may be used even if the apical part ...
