Periodic Gamma-Ray Modulation of the Blazar PG 1553+113 Confirmed by Fermi-LAT and Multiwavelength Observations

The Astrophysical Journal
A 2.1 yr periodic oscillation of the gamma-ray flux from the blazar PG 1553+113 has previously been tentatively identified in ∼7 yr of data from the Fermi Large Area Telescope.

A Short History of the First 50 Years: From the GRB Prompt Emission and Afterglow Discoveries to the Multimessenger Era

Universe
More than fifty years have elapsed from the first discovery of gamma-ray bursts (GRBs) with American Vela satellites, and more than twenty-five years from the discovery with the BeppoSAX satellite of the first X-ray afterglow of a GRB.

Understanding Postdeposition Treatments of Hole‐Transporting Self‐Assembling Molecules for Perovskite/Silicon Tandem Solar Cells

Advanced Functional Materials, EarlyView.
The influence of postdeposition treatments on the formation of self‐assembling (mono)layers commonly utilized as hole transport layers in perovskite‐based solar cells is thoroughly investigated. The implementation of a washing step and an annealing step at temperatures exceeding the current literature standards leads to an enhanced layer quality and ...

Cu2O/Cu Chiral Catalysts for Highly Selective Solar‐Assisted CO2‐to‐CO Electroreduction

Advanced Functional Materials, EarlyView.
To address the poor target‐product selectivity of the eCO2RR, breakthrough approaches based on the chiral‐induced spin selectivity phenomenon enhance the Faradaic efficiency (FE) for target hydrocarbons, such as CO. To induce this spin polarization strategy in Cu2O/Cu catalysts, it is proposed using amine‐based intermediate organic molecules with ...

Synergistic Osteogenesis After Co‐Administration of cmRNAs Encoding BMP‐2 and BMP‐7 Utilizing a Transcript‐Activated Matrix

Advanced Functional Materials, EarlyView.
This study demonstrates that the dual delivery of BMP‐2/‐7 coding cmRNAs for bone healing is demonstrated as feasible, safe, and highly osteogenic. Compared to single BMP‐2 or BMP‐7 cmRNAs, the combination enhances the production of both mineral and organic components of the extracellular matrix when delivered using a collagen‐HA scaffold, supporting ...
