Microwave Quasi-periodic Pulsation with Millisecond Bursts in A Solar Flare on 2011 August 9

, 2012
An peculiar microwave quasi-periodic pulsation (QPP) accompanying with a hard X-ray (HXR) QPP of about 20 s duration occurred just before the maximum of an X6.9 solar flare on 2011 August 9. The most interesting is that the microwave QPP is consisting of

The early life of millisecond magnetars [PDF]

AIP Conference Proceedings, 2019
Some neutron stars may be born spinning fast and with strong magnetic fields---the so-called \emph{millisecond magnetars}. It is important to understand how a star's magnetic axis moves with respect to the spin axis in the star's early life, as this effects both electromagnetic and gravitational wave emission.

Tailoring Hole‐Blocking Layers Enables a Versatile Approach for Fast Photomultiplication‐Type Organic Photodetectors

Advanced Functional Materials, EarlyView.
This study investigates the role of hole‐blocking layers (HBLs), particularly the combination of two HBLs in photomultiplication‐type organic photodetectors (PM‐OPDs), which results in high gain and record‐fast response. The proposed HBL strategy also allows for the use of photoactive layer with balanced donor–acceptor stoichiometry, which can be ...

Study of Tensile Strength of Aluminum Alloy Caused by Pulsed Laser Drilling

Metals, 2022
In the process of pulsed laser drilling, the material properties in the heat-affected zone will change due to the thermal effect of the laser. To study the effect of this change on the material tensile strength, two lasers were used to punch the standard

On the progenitors of millisecond pulsars by the recycling evolutionary channel

, 2011
The recycling model suggested that low-mass X-ray binaries (LMXBs) could evolve into binary millisecond pulsars (BMSPs). In this work, we attempt to investigate the progenitor properties of BMSPs formed by the recycling evolutionary channel, and if sub ...

Optical pulsations from a transitional millisecond pulsar [PDF]

, 2017
Weakly magnetic, millisecond spinning neutron stars attain their very fast rotation through a 1E8-1E9 yr long phase during which they undergo disk-accretion of matter from a low mass companion star. They can be detected as accretion-powered millisecond X-

Illuminating the Origins of Ferroelectric‐Induced Photocurrent and Hole Lifetime Enhancement in BaTiO3 Photoanodes

Advanced Functional Materials, EarlyView.
The use of ferroelectric polarization to enhance photocatalytic and photoelectrocatalytic activity is an innovative, and increasingly studied route to improve the spatial separation of charge carriers and therefore enhance catalytic efficiency. These results demonstrate how the intrinsic properties of a ferroelectric film can extend charge carrier ...

Microplate Active Migration Emerging From Light‐Induced Phase Transitions in a Nematic Liquid Crystal

Advanced Functional Materials, EarlyView.
A quasi‐2D, light‐absorbing platelet embedded in a thermotropic nematic liquid crystal is activated with light irradiation. Depending on the light intensity, the platelet induces a localized nematic‐isotropic phase transition that triggers the motion. Using different confinements, the platelet can glide in a 2D regime or tilt and glide in a 3D regime ...
