Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

open access: yesAngewandte Chemie, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Reactors and Power Transformers

IEEE Transactions on Power Apparatus and Systems / Technical Operations Committee, 1981
A method is presented which will enable the test engineer to rapidly determine the optimum parameters of a test circuit for the generation of switching surges on high voltage shunt reactors and power transformers. For any given impulse generator and load inductance the selected parameters will result in the maximum efficiency of the test circuit ...

Power Transformers and Reactors

CIGRE Green Books, 2020
This chapter focuses on how changes in the electricity supply system will affect the life cycle of power transformers and reactors. This chapter gives a brief overview of the role of transformers in the development of the power system and on some of the developments in design, manufacturing and test.

Corrosive Sulfur Induced Failures in Oil-Filled Electrical Power Transformers and Shunt Reactors

open access: yesIEEE Transactions on Power Delivery, 2009
The nature and causes of corrosive sulfur induced failures are examined in oil-filled transformers and shunt reactors. Copper sulfide, which is formed when the corrosive sulfur in a mineral oil reacts with the copper conductors, is likely to diffuse into
