Surface Adhesion Engineering for Armored Metasurfaces and Beyond

Advanced Science, EarlyView.
Targeting primary causes of dysfunctionality in optical systems, an “armored” metasurface is developed based on Persson's model and Hertzian theory, enabling anti‐dust, anti‐scratch, anti‐impact, and anti‐water, heat resistance capabilities, alongside excellent optical antireflection performance.

Productivity and Impact of Radio Telescopes [PDF]

Publications of the Astronomical Society of the Pacific, 2006
In 2001, 836 papers appearing in 15 journals reported and/or analyzed data collected with ground-based radio, millimeter, and submillimeter telescopes, plus the HALCA, COBE, and SWAS satellites and a few balloon-borne detectors. More than 80 telescopes were represented, including 36 that were each responsible for five or more papers.

Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

Advanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

A Candidate Period of 4.605 Days for FRB 20121102A and One Possible Implication of Its Origin

The Astrophysical Journal
A firm establishment of the presence or the lack of periodicity in repeating fast radio bursts is crucial for determining their origins. Here, we compile 1145 radio bursts of FRB 20121102A with fluence larger than 0.15 Jy ms from observations using the ...

LUNASKA simultaneous neutrino searches with multiple telescopes

, 2011
The most sensitive method for detecting neutrinos at the very highest energies is the lunar Cherenkov technique, which employs the Moon as a target volume, using conventional radio telescopes to monitor it for nanosecond-scale pulses of Cherenkov ...

A Robotic Urinary Bladder Enabling Volume Monitoring and Assisted Micturition

Advanced Intelligent Systems, EarlyView.
An implantable robotic bladder is presented that can store urine in an origami‐designed enclosure. An inductance sensing principle can monitor and transfer the urine volume in real‐time. It can actively expand based on the amount of urine collected from kidneys and apply on‐demand mechanical compression to assist urination.

A New 6–15 GHz Solar Radio Observation System

The Astrophysical Journal Supplement Series, 2023
In this study, we have developed a centimeter-band solar radio telescope covering the 6–15 GHz frequency band. The radio telescope has the outstanding advantages of a large instantaneous sampling bandwidth and wide frequency coverage.

No bursts detected from FRB121102 in two 5-hour observing campaigns with the Robert C. Byrd Green Bank Telescope [PDF]

, 2018
Here, we report non-detection of radio bursts from Fast Radio Burst FRB 121102 during two 5-hour observation sessions on the Robert C. Byrd 100-m Green Bank Telescope in West Virginia, USA, on December 11, 2017, and January 12, 2018.
