Hydrogen-induced tunable remanent polarization in a perovskite nickelate
Materials with field-tunable polarization are of broad interest to condensed matter sciences and solid-state device technologies. Here, using hydrogen (H) donor doping, we modify the room temperature metallic phase of a perovskite nickelate NdNiO3 into an ...
Nature Portfolio20243D Printing of Customizable Transient Bioelectronics and Sensors
Danick Briand, Nicolas Francis Fumeaux
Transient electronics have emerged as a new category of devices that can degrade after their functional lifetime, offering tremendous potential as disposable sensors, actuators, wearables, and implants. Additive manufacturing methods represent a promising ...
2024Tomographic microscopy of functionally graded polymer-derived SiCN ceramics with tunable gradients
Jürgen Brugger, Lorenz Hagelüken
Polymer-derived ceramics (PDCs) are a very attractive class of materials due to their excellent properties such as resistance to high temperatures and harsh environments, adjustability of mechanical and functional behavior, and compatibility with a broad r ...
London2024Influence of Si3N4 fillers and pyrolysis profile on the microstructure of additively manufactured silicon carbonitride ceramics derived from polyvinylsilazane
In this work, various methods were used to improve the printability of a photocurable polyvinylsilazane resin filled with silicon nitride particles for digital light processing. The developed resin was used as a preceramic polymer for polymer-to-ceramic co ...
Taylor & Francis Ltd2024Quantifying mass transport limitations in a microfluidic CO2 electrolyzer with a gas diffusion cathode
Sophia Haussener, Venu Gopal Agarwal
A gas diffusion electrode (GDE) based CO2 electrolyzer shows enhanced CO2 transport to the catalyst surface, significantly increasing current density compared to traditional planar immersed electrodes. A two-dimensional model for the cathode side of a micr ...
