An X-Ray Study of the Supernova Remnant G290.1-0.8 [PDF]

open access: yes, 2001
G290.1-0.8 (MSH 11-61A) is a supernova remnant (SNR) whose X-ray morphology is centrally bright. However, unlike the class of X-ray composite SNRs whose centers are dominated by nonthermal emission, presumably driven by a central pulsar, we show that the

Optical Emission from Aspherical Supernovae and the Hypernova SN 1998bw

open access: yes, 2005
A fully 3D Monte Carlo scheme is applied to compute optical bolometric light curves for aspherical (jet-like) supernova explosion models. Density and abundance distributions are taken from hydrodynamic explosion models, with the energy varied as a ...

Synthesis of antibacterial polyether biguanide curing agent and its cured antibacterial epoxy resin

open access: yesDesigned Monomers and Polymers, 2021
At present, bacteria continue to threaten human health, and the resistance of bacteria to antibiotics continues to increase, so the development of new antibacterial agents and antibacterial materials is increasingly important to ensure human health.

CO J = 2 - 1 Emission from Evolved Stars in the Galactic Bulge

open access: yes, 2013
We observe a sample of 8 evolved stars in the Galactic Bulge in the CO J = 2 - 1 line using the Submillimeter Array (SMA) with angular resolution of 1 - 4 arcseconds.

Skeleton Enhanced Dispersed Lubricant Particle Based Triboelectric Nanogenerator for Droplet Energy Harvesting

open access: yesAdvanced Science, EarlyView.
A stretchable, slippery triboelectric nanogenerator (SS‐TENG) is presented for efficient droplet energy harvesting. A novel phase separation method is created to prepare a durable, flexible triboelectric layer with skeleton‐embedded, dispersed lubricant particles.

Linearly polarized GHz magnetization dynamics of spin helix modes in the ferrimagnetic insulator Cu2OSeO3

open access: yesScientific Reports, 2017
Linear dichroism — the polarization dependent absorption of electromagnetic waves— is routinely exploited in applications as diverse as structure determination of DNA or polarization filters in optical technologies.

Yields of Population III Supernovae and the Abundance Patterns of Extremely Metal-Poor Stars

open access: yes, 2005
The abundance patterns of extremely metal-poor (EMP) stars provide us with important information on nucleosynthesis in supernovae (SNe) formed in a Pop III or EMP environment, and thus on the nature of the first stars in the Universe.

Preparation Method and Performance Study of Nanocellulose/Epoxy Resin Composite Materials Modified by Multiple Approaches

open access: yesHigh Voltage, EarlyView.
ABSTRACT Nanocomposites are pivotal for enhancing epoxy resin performance, but traditional inorganic nanofillers' poor compatibility and nonrecyclability pose environmental concerns. This study utilises recyclable organic cellulose nanocrystals (CNC) to explore their modification impact on epoxy composite properties. Through infrared spectroscopy and X‐
