The machining torch movement for the rectangular plasma sheet metal cut.
PLoS ONE, 2023 The sheet metals can be cut into rectangular or irregular pieces, where the main objective is to minimize the sheet metal's physical waste. However, the operating time, the number of movements to cut all rectangles edges, and the cutting process quality,

Advanced Science, EarlyView.A “ceramic self‐toughening strategy” is introduced for enhancing the plasticity and thermal shock resistance of (Hf─Zr─Ti)C coatings through twin toughening‐driven martensitic transformations in oxide scales. It facilitated the formation of stable, dense, and high‐toughness oxide scales after repeat ablation, and endowed prepared coatings with superior

Advanced Electronic Materials, EarlyView.Proton‐coupled electron transfer doping with benzoquinone is applied to p‐dope dense films of semiconducting single‐walled carbon nanotubes. The doping efficiency depends on the pH of the doping solution and the bandgap of the nanotubes. The highest conductivities and power factors are achieved for small‐bandgap nanotubes, remaining stable for over 120

NOx Production via an Atmospheric Microwave Air Plasma Torch
Chemie Ingenieur Technik, EarlyView.In order to accommodate the growing need of fertilizers, reduce their waste, production costs of precursors and strive towards climate neutrality, the synthesis of NOx by means of a microwave plasma torch has been investigated. The atmospheric pressure reactor, operated on air, allows for a flexible, on‐demand production even in‐loco at low costs ...
