Acceleration of cosmic rays and gamma-ray emission from supernova remnants in the Galaxy

, 2013
Galactic cosmic rays are believed to be accelerated at supernova remnant shocks. Though very popular and robust, this conjecture still needs a conclusive proof.

Development of Photo‐Biocatalytic Redox System for Asymmetric Synthesis of Optically Active Amines Using Blue Light and Transaminases. A Case Study Toward Mavacamten

Advanced Synthesis &Catalysis, EarlyView.
Abstract α‐Chiral amines are versatile building blocks for the asymmetric synthesis of optically pure high‐added‐value chemicals, including pharmaceuticals, agrochemicals, and natural products. Herein, we report a one‐pot, two‐step sequential deracemization of racemic sec‐alcohols to optically enriched primary amines throught a photo‐biocatalytic ...

A Supramolecular Material for Controlling Kiwifruit Bacterial Canker

Advanced Science, EarlyView.
The matrine‐5‐methylsalicylic acid salt (MOS) is reported for its excellent antibacterial activity against Pseudomonas syringae pv. actinidiae (Psa), with advanced cell membrane penetration ability and strong affinities for potential targets. Furthermore, a nanosupramolecular delivery system MOS@hydroxypropyl‐beta‐cyclodextrin (HPCD) with improved ...

Neutrino emission of Fermi supernova remnants

, 2011
The Fermi $\gamma$-ray space telescope reported the observation of several Galactic supernova remnants recently, with the $\gamma$-ray spectra well described by hadronic $pp$ collisions. The possible neutrino emissions from these Fermi detected supernova

Are the Models for Type Ia Supernova Progenitors Consistent with the Properties of Supernova Remnants? [PDF]

, 2007
We explore the relationship between the models for progenitor systems of Type Ia supernovae and the properties of the supernova remnants that evolve after the explosion.

Proton Acceleration with Relativistic Electromagnetic Shock

Advanced Science, EarlyView.
New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

Organocatalytic C─O Bond Cleavage and Asymmetric Transformations via [1,3]‐Sigmatropic Rearrangement

Advanced Science, EarlyView.
A direct asymmetric strategy for fulfilling the functional group transfer by aryl ether cleavage and migration is developed, representing the first Brønsted base‐catalyzed asymmetric [1,3]‐sigmatropic rearrangement reaction. The resulting chiral benzofuran products generated through this strategy exhibit significant 3D‐dimensionality and demonstrate ...

The infancy of supernova remnants: evolving a supernova into its remnant in 3D [PDF]

Proceedings of the International Astronomical Union, 2017
AbstractRecently, first neutrino-driven supernova explosions have been obtained in 3D, self-consistent, first-principle simulations, these models are still not always exploding robustly and, in general, the explosions are not sufficiently energetic. To constrain the explosion mechanism, and the related uncertainties, it is thus very helpful to consider

Radiation Hardened Infrared Photodetectors Based on a Narrow Bandgap Conjugated Polymer Semiconductor

Advanced Electronic Materials, EarlyView.
A blackbody‐sensitive infrared photodetector comprised of an open‐shell conjugated polymer demonstrates high sensitivity without cooling and exceptional radiation hardness, surpassing inorganic compound semiconductor devices. This functionality, inherent to the polymer semiconductor, provides a new frontier for low‐cost, size, weight, and power space ...
