Stable and eco-friendly organic solar cells can be made from lignin, one of the most abundant organic compounds found in nature. It has now been demonstrated by researchers at Linköping University and the Royal Institute of Technology (KTH) that organic solar cells may be further enhanced by using untreated kraft lignin.
Photonic integrated circuits (PICs) are compact devices that combine multiple optical components on a single chip. They have a wide range of applications in communications, ranging, sensing, computing, spectroscopy, and quantum technology.
A process to present phosphorus and nitrogen atoms into polycyclic molecules was developed by Jan J. Weigand, Professor, Phosphorus Chemist, Dresden University of Technology, in partnership with a multitalented group.
Hopfions, magnetic spin structures predicted decades ago, have become a hot and challenging research topic in recent years. In a study published in Nature today, the first experimental evidence is presented by a Swedish-German-Chinese research collaboration
In line with expectations, new quantum noise experiments conducted at Rice University revealed an unusually quiet “strange metal” quantum material. The measurements of quantum charge fluctuations, or "shot noise," which were published in Science, offer the first concrete proof that electricity appears to flow through peculiar metals in a peculiar liquid-like form that defies easy explanation in terms of quantized charge packets, or quasiparticles.
