Producing hydrogen gas from water using sunlight
One prospective source of renewable energy is hydrogen gas produced from water with the aid of sunlight. Researchers at Linköping University, Sweden, have developed a material, nanoporous cubic silicon carbide, that exhibits promising properties to capture solar energy and split water for ...
Ion-selective electrocatalysis on conducting polymer electrodes -- improving the performance of redox flow batteries
Researchers at the Laboratory of Organic Electronics, Linköping University, have for the first time demonstrated an organic battery. It is of a type known as a "redox flow battery", with a large capacity that can be used to store energy from wind turbines and solar cells, and as a power bank for ...
Soft and biocompatible materials for optical, catalytic, electrical and biomedical applications
When nanocellulose is combined with various types of metal nanoparticles, materials are formed with many new and exciting properties. They may be antibacterial, change colour under pressure, or convert light to heat. "To put it simply, we make gold from nanocellulose", says Daniel Aili, associate ...
Polymer gels with tunable ionic Seebeck coefficient for ultra-sensitive printed thermopiles
Scientists at the Laboratory of Organic Electronics have developed an ultra-sensitive heat sensor that is flexible, transparent and printable. The results have potential for a wide range of applications - from wound healing and electronic skin to smart buildings. The ultra-sensitive heat sensor ...
A multiparameter Pressure-Temperature-Humidity Sensor based on Mixed Ionic-Electronic Cellulose Aerogels
Cellulose soaked in a carefully designed polymer mixture acts as a sensor to measure pressure, temperature and humidity - at the same time! The measurements are completely independent of each other. The sensor may be highly significant in fields such as robotics, healthcare and security. The ...
The organic polymer PEDOT is probably one of the world's most intensely studied materials. Despite this, researchers at Linköping University have now demonstrated that the material functions in a completely different manner than previously believed. The result has huge significance in many fields ...
Inorganic metal halide perovskite-based photodetectors for optical communication applications
Researchers at the universities in Linköping and Shenzhen have shown how an inorganic perovskite can be made into a cheap and efficient photodetector that transfers both text and music. "It's a promising material for future rapid optical communication", says Feng Gao, researcher at Linköping ...
LiU researcher Klas Tybrandt has put forward a theoretical model that explains the coupling between ions and electrons in the widely used conducting polymer PEDOT:PSS. The model has profound implications for applications in printed electronics, energy storage in paper, and bioelectronics. One of ...
A discovery of how to control and transfer spinning electrons paves the way for novel hybrid devices that could outperform existing semiconductor electronics. In a study published in Nature Communications, researchers at Linkoping University in Sweden demonstrate how to combine a commonly used ...
"We are the first in the world to present a logic circuit, in this case a transistor, that is controlled by a heat signal instead of an electrical signal," states Professor Xavier Crispin of the Laboratory of Organic Electronics, Linköping University. The heat-driven transistor opens the ...
