γ-rays from the excited 54Ca fragment were measured in-flight by a large solid-angle γ-ray telescope array. As shown in Fig. 69, the excitation energy of the first 2+ levels of N=32 and 34 isotones are clearly larger than of the neighboring isotones. Furthermore, quasifree knockout...
An efficiency of 4.1% was obtained in the frontside illumination geometry using a 1 microm long array of transparent TiO(2) nanotubes subjected to a TiCl(4) treatment and then sensitized with the Ru-TPA-NCS dye. Open circuit voltage decay measurements give insight into the recombination behavior...
While a number of indicators of solar activity exist, by far the most commonly employed is still the smoothed relative sunspot numberR; the “Holy Grail” of sunspot cycle prediction attempts is to get R right for the next maximum. We, therefore, start by briefly introducing the sunspot numbe...
In this work, we investigate such resonantly converted monochromatic radio signal within the solar observation data collected by Low Frequency Array (LOFAR) telescope87. To calculate the signal, we carry out simulations of EM wave propagation inside solar corona of the quiet Sun. Subsequently, we c...
$$a_{\mathrm{step}}\left( E \right) =\left\{\begin{array}{cc} {0,} & E \, < \, E_{\mathrm{g}} \\ {1}, & E \ge E_{\mathrm{g}}\end{array}\right.$$ (9) Fig. 3 shows the contour plot of the resulting efficiency η as a function of band-gap energy Eg and ...
96. We are using LOFAR data made in the tied-array beam mode. While this mode offers a nice angular resolution87, the field of view (FOV) of each LOFAR beam is significantly smaller than the total angular span of the Sun. Consequently, we expect the scattering effect to suppress the ...

Different from 3D perovskites, 2D perovskites have a layered crystal structure and offer greater synthetic functionalities, such as high stability and film quality, and tunability of optoelectronic prop- erties by incorporating a wide array of organic cations into the 2D framework. 2D perovskites can...
[105,106,107,108]. The isolation of graphene and various 2D atomic materials with surfaces free of dangling bonds has sparked significant interest in vdW integration, which enables the creation of an array of heterojunctions with atomically clean and electronically sharp interfaces. This not only ...
