Date Time 3D-printed bioresorbable airway stent An ETH Zurich research team is using 3D printing to produce a new type of bioresorbable airway stent. This could greatly simplify the future treatment of upper airway obstruction. Narrowing of the trachea or the main bronchi due to injury or illness can end very badly. If patients get too little oxygen, they risk suffocating and often need medical help as quickly as possible. Surgeons insert stents made of medically usable silicone or metal as a way of treating these patients. Although they quickly bring relief, the implants also have disadvanta...

Revealing a Pauli Crystal January 13, 2021• Physics 14, 5 A novel, high-resolution fluorescence imaging technique reveals a pattern, known as a Pauli crystal, that can emerge in a cloud of trapped, noninteracting fermions. Figure 1: As a consequence of the Pauli exclusion principle, a few fermions trapped by lasers self-organize into a periodic structure called a Pauli crystal. By combining single-particle snapshots of the system, Marvin Holton and colleagues measure the multiparticle correlations that reveal the formation of a Pauli crystal.As a consequence of the Pauli exclusion pr...

Researchers Identify Novel Topological Properties in Cobalt Disulfide Written by AZoMDec 21 2020 The Schoop Lab, which is heading an association of institutions both in the United States and overseas, has reported unexpected new topological characteristics of cobalt disulfide (CoS 2)—a magnetic pyrite—expanding one’s interpretation of electrical channels in this extensively 2, in comparison to the theoretical prediction. Image Credit: Figure courtesy of the Schoop Lab. The researchers used ab-initio calculations and angle-resolved photoelectron spectroscopy and observed that bulk CoS ...

 E-Mail IMAGE: A Princeton-led team of physicists have discovered that, under certain conditions, interacting electrons can create what are called "topological quantum states, " which, has implications for many technological fields of study, especially... view more  Credit: Kevin Nuckolls, Department of Physics, Princeton University Electrons inhabit a strange and topsy-turvy world. These infinitesimally small particles have never ceased to amaze and mystify despite the more than a century that scientists have studied them. Now, in an even more amazing twist, physicists have disco...
