Advanced Science, EarlyView.How do chemical and physical processes involving multiple phases develop on compact astrophysical objects such as white dwarf stars? Herein, entropy‐driven self‐assembly of rod‐shaped nanoparticles in centrifugal acceleration fields up to 7251 times the gravity of Earth is investigated, where strong acceleration fields accelerated the kinetics of phase

A curve of nilpotent Lie algebras which are not Einstein nilradicals [PDF]
arXiv, 2008 The only known examples of noncompact Einstein homogeneous spaces are standard solvmanifolds (special solvable Lie groups endowed with a left invariant metric), and according to a long standing conjecture, they might be all. The classification of Einstein solvmanifolds is equivalent to the one of Einstein nilradicals, i.e.

Realizing Intrinsically Ultralow and Glass‐Like Thermal Transport via Chemical Bonding Engineering
Advanced Science, EarlyView.Lattice thermal conductivity can be effectively suppressed by introducing a S2 − anion into the bridging position between the Ag–Ag bond in the Ag6 octahedron, which weakens the Ag–Ag bond within the octahedral structure and enhances phonon‐phonon scattering rates. Abstract Crystals exhibiting glass‐like and low lattice thermal conductivity (κL$\kappa_{

Non-naturally reductive Einstein metrics on normal homogeneous Einstein manifolds [PDF]
arXiv, 2017 It is an important problem in differential geometry to find non-naturally reductive homogeneous Einstein metrics on homogeneous manifolds. In this paper, we consider this problem for some coset spaces of compact simple Lie groups. A new method to construct invariant non-naturally reductive Einstein metrics on normal homogeneous Einstein manifolds is ...

Advanced Science, EarlyView.A highly efficient extracorporeal device for treating bacteremia is developed by integrating microfluidic bacterial margination and engineered cell‐depleted thrombi strategically constructed in the device. The rodent models, severely infected with antibiotic‐resistant bacteria, recover from bacteremia after two subsequent extracorporeal blood ...

Tunable Polariton Rabi Oscillation in Phase‐Changing Perovskite Microcavities
Advanced Science, EarlyView.This work demonstrated the tunable Rabi oscillation of exciton‐polaritons in MAPbBr3 perovskites due to the emergence of ferroelectricity during the crystallographic phase transition. Both the Rabi oscillation and exciton oscillator strength exhibit an unusual temperature dependence that is related to the emergence of ferroelectricity in the tetragonal
