Energy Science &Engineering, EarlyView.ABSTRACT In power networks, low‐frequency oscillations—particularly inter‐area oscillations—pose a serious threat to system stability because of disruptions like short‐circuit faults and the increasing use of renewable energy sources like wind farms. To lessen the negative impacts of time delays when sending distant signals, this study presents a novel

Simple Method for Transforming Liquid Silicone Oils Into High‐Quality Solid Silicone Resins
Helvetica Chimica Acta, EarlyView.A cost‐effective, sustainable method for synthesizing highly crosslinked silicone resins from silicone oil (linear polyorganylsiloxanes) was developed. The process achieved up to 80% yield of resins with silicone oligomers as a byproduct. Solid‐state NMR and EPR spectroscopy confirmed resin structure and pointed towards a radical reaction mechanism ...
