Dual‐Surface Reaction Enabled Organic–Inorganic Hybrid Photodiodes for Faint Light Detection and Imaging

Advanced Functional Materials, EarlyView.
This work proposes a dual‐surface reaction strategy to optimize the interfacial contacts in organic–inorganic photodetectors. 1,4,5,8,9,11‐hexaazatriphenylene hexacarbonitrile (HAT‐CN) and ytterbium layers are designed to react with the Si surface, thus minimizing noise.

Proteins, Processing, and Properties of Adhesive Fluid Condensates Purified from Mussels

Advanced Functional Materials, EarlyView.
Mussels exhibit an unmatched proficiency for adhering to wet surfaces in salty environments—a remarkable ability that could inspire new biomedical and technical glues. The fluid protein condensates used to form the underwater mussel glue are extracted, reconstituted and characterized with advanced spectroscopy and nanomechanical analysis, revealing ...

Metallofullerenol Sc3N@C80(OH)18: A New Generation Radioprotector Protecting Human Erythrocytes Against Multiple Biochemical Damage Modes Upon Gamma Irradiation, Identifying It as a Scavenger of Short‐ and Long‐Lived Radicals

Advanced Healthcare Materials, EarlyView.
Metallofullerenol Sc3N@C80(OH)18 demonstrates strong radioprotective properties as a scavenger of both short‐ and long‐lived radicals. The study reveals protection of human erythrocytes from γ‐radiation–induced biochemical damage via post‐irradiation removal of primary and secondary reactive oxidants, supported by pulse radiolysis kinetics.

SLAC T-510: Radio emission from particle cascades in the presence of a magnetic field

EPJ Web of Conferences, 2017
Cosmic ray induced particle cascades radiate in radio frequencies in the Earth’s atmosphere. Geomagnetic and Askaryan emission provide an effective way to detect ultra-high energy cosmic rays.

Cosmic ray ensembles as signatures of ultra-high energy photons interacting with the solar magnetic field [PDF]

Journal of Cosmology and Astroparticle Physics, 2018
Propagation of ultra-high energy photons in the solar magnetosphere gives rise to cascades comprising thousands of photons. We study the cascade development using Monte Carlo simulations and find that the photons in the cascades are spatially extended ...

Molecular Nanosolids Generation by Vapor Jet Desublimation

Advanced Materials, EarlyView.
A single‐step, solvent‐free approach to fabricate nanoparticles of small organic molecules is demonstrated, using a nitrogen‐propelled vapor jet, enabling tunable particle morphology and crystallinity. Pharmaceutical, flavoring, dyeing and electronics‐relevant molecules are used, demonstrating process generalizability.

Ultra-high-energy cosmic-ray hotspot observed with the telescope array surface detectors

, 2016
The Telescope Array (TA) collaboration has reported on an indication of the excess flux of ultra- high energy cosmic rays (UHECRs) with E > 57 EeV, located near the Ursa Major cluster [1]. Corresponding sky region was called the 'hotspot'. In the present

From Single to Multi‐Glass/Ceramic Microarchitectures via Two‐Photon Lithography

Advanced Optical Materials, EarlyView.
Two‐photon lithography enables precise oxide microarchitectures. A transition is made from single to multi‐glass/ceramic materials by integrating spatially varied compositions via fluidic photoresin exchange. Low‐temperature annealing and optical characterization (i.e., cathodoluminescence, fluorescence microscopy) reveal how post‐treatment affects the
