Type Ia Supernovae inside Planetary Nebulae: Shaping by Jets
, 2013 Using 3D numerical hydrodynamical simulations we show that jets launched prior to type Ia supernova (SN Ia) explosion in the core-degenerate scenario can account for the appearance of two opposite lobes ('Ears') along the symmetry axis of the SN remnant (

Nanolayer‐Encapsulated Stretchable Liquid‐Metal Sheets for Thermal Management
Advanced Functional Materials, EarlyView.A stretchable liquid metal sheet with both high thermal conductivity and mechanical flexibility is developed. Its trilayer structure, comprising copper‐particle‐dispersed gallium liquid metal encapsulated by styrene‐butadiene‐styrene nanosheets, shows 40.4 W m−1 K−1 conductivity, elongation exceeding 200%, and retention of 96% of its initial ...

Neutrino scattering in supernovae and spin correlations of a unitary gas
, 2017 Core collapse supernova simulations can be sensitive to neutrino interactions near the neutrinosphere. This is the surface of last scattering. We model the neutrinosphere region as a warm unitary gas of neutrons.

The Impact of a Supernova Explosion in a Very Massive Binary
, 2008 We consider the effect of a supernova (SN) explosion in a very massive binary that is expected to form in a portion of Population III stars with the mass higher than 100$M_\odot$.
