the body-centered cubic phase of iron possesses the viscosity close to that of a liquid iron. The high attenuation of sound in the inner core is due to the unique diffusion characteristic of the body-centered cubic phase. The low viscosity of iron in the inner core enables the convection an...

The mechanism by which the Earth’s magnetic field is generated is thought to be thermal convection in the metallic liquid iron core. Here we present results of a suite of self-consistent spherical shell computations with ultra-low viscosities that replicate this mechanism, but using diffusivities ...
The use and maintenance of eVTOL aircraft are cheaper than those of helicopters. With the flight put into commercial operation in the future, the airfare for a one-way passenger could be reduced to 200 to 300 yuan (about 28 to 41 U.S. dollars), according to AutoFlight's preliminary cost ...
The typical structure of LIBs (Fig.1a) unveils the multiple issues that can impact their performance at LT [10,11,12,13,14,15,16,17]. Firstly, the viscosity of liquid electrolyte experiences a sharp escalation and even solidification, resulting in a decrease in wettability and ionic conductivi...
Ultralight dark photons and axions are well-motivated hypothetical dark matter candidates. Both dark photon dark matter and axion dark matter can resonantly convert into electromagnetic waves in the solar corona when their mass is equal to the solar plas
The inner thin low-friction layer is injection transfer, or injection/blow moulded on a coare, using material free from fibre and/or other form of abrasive fillers. The prod. is covered with a hard or a soft elastic polymer to which the low-friction layer bonds firmly. The low-friction ...
Measurement parameters were chosen as follows: refractive index R = 2.58 and absorption k = 0.001 for TiO2 rutile at laser wavelength λ =633 nm of the Zetasizer device; dispersant refractive index RI = 1.361, viscosity cP = 1.08, and dispersant dielectric constant ε =...
An enduring mystery about Earth has been the age of its solid inner core. Plausible yet contrasting core thermal conductivity values lead to inner core growth initiation ages that span 2 billion years, from ~0.5 to >2.5 billion years ago. Palaeomagnetic data provide a direct probe of past cor...
Volcanism on Earth and on other planets and satellites is dominated by the eruption of low viscosity magmas. During explosive eruption, high melt temperatures and the inherent low viscosity of the fluidal pyroclasts allow for substantial post-fragmentati
