Fracture-induced mechanophore activation and solvent healing in poly(methyl methacrylate)
… for Double Cleavage Drilled Compression (DCDC) fracture testing. The DCDC specimens, containing increasing concentrations of solvent microcapsules, are tested and then allowed to heal for a fixed period of time before a second DCDC test. The healing efficiency of each material system is …

High Efficiency Topologies for Dual Voltage Inputs
Growing concerns about climate change have led governments to update their policies to require better efficiency in appliance power supplies. Additionally, consumer demand and economic drives in the last few decades have reduced the power supply cost and size. Another emerging trend in recent years …
