An asymmetric non‐fullerene acceptor BTP‐FT is developed by extending the end group of Y6‐BO with thiophene. The conformation of the molecule is determined by the noncovalent F···S interaction as demonstrated by 2D NMR and simulations. An efficiency of 18.39% is achieved in the resulting ternary solar cells processed from toluene.

Radio Astronomy and the Radio Regulations [PDF]
This article gives a brief introduction to the status of radio astronomy within the International Telecommunication Union (ITU), the body which coordinates global telecommunications. Radio astronomy entered the ITU arena in 1959 as a relative latecomer.

DATA ON SOLAR RADIO EMISSION WITH SOME NOTES [PDF]
1957-03-25The results of observations by 3750 Mc/s and 9400 Mc/s radiometers are tabulated. The daily flux density at both frequencies has a correlation coefficient of 0.95, and the S-componen t at 9400 Mc/s is 0.8 times as large as that at 3750 Mc/s ...

A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

EuSc₂Te₄, an antiferromagnetic semiconductor, exhibits a nonlinear Hall effect (NLHE) characterized by quadratic current–voltage behavior. Combined experimental and theoretical studies reveal that this NLHE is linked to its antiferromagnetism and involves contributions from the quantum metric.

Techniques of Radio Astronomy [PDF]
This chapter provides an overview of the techniques of radio astronomy. This study began in 1931 with Jansky's discovery of emission from the cosmos, but the period of rapid progress began fifteen years later. From then to the present, the wavelength range expanded from a few meters to the sub-millimeters, the angular resolution increased from degrees ...

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires
In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Al1‐xScxN‐Based Ferroelectric Domain‐Wall Memristors
(a) Conductive atomic force microscopy (CAFM) image of the initial state bidomain structure of the Al0.85Sc0.15N (a) showing an enhanced conductivity of the head‐to‐head domain boundary. (b) CAFM image of the same area after application of several −65 V, 1 s voltage pulses showing lower conductivity of the generated tail‐to‐tail domain walls.
