Nachtsicht ins All mit dem bloßen Auge: Sag mir, wie weit die Sterne steh'n

Physik in unserer Zeit, EarlyView.
Beim Blick in den Nachthimmel sehen wir ohne optische Hilfsmittel und abhängig von der lokalen Lichtverschmutzung viele Hundert bis maximal einige Tausend Sterne und auch einige Galaxien. Aber wie weit sind diese von uns entfernt? Und bis zu welchen maximalen Entfernungen können wir Objekte im Weltall mit dem bloßen Auge wahrnehmen?

Coating of High Melting Explosive Particles by Nitrotriazolone to Formulate Composite Nanoparticles by Spray Flash Evaporation

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT The balance between performance and safety of high explosives is at the heart of the current studies, and new ways of combining safety and performance have hence been elaborated. This study focuses on a mixture of 3‐nitro‐1,2,4‐triazol‐5‐one (NTO) and octogen (high melting explosive [HMX]).

Synthesis, Characterization, and Energetic Performance of a New Copper Complex Based on 3,4,5‐Trinitro‐1H‐pyrazole

Propellants, Explosives, Pyrotechnics, EarlyView.
A new copper compound based on the trinitropyrazolate (TNP−) ligand ammonium copper(II) (tetrakis)trinitropyrazolate [(NH4+)2CuII(TNP−)4] has been prepared and structurally characterized, which displays different thermo‐chemical behaviour and sensitivity properties from the parent compound ammonium 3,4,5‐trinitropyrazolate. ABSTRACT The urgent need for

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

Advanced Quantum Technologies, EarlyView.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

Solid‐state polymer electrolytes: Decoupling lithium‐ion transport from relaxation dynamics of polymer chain segments

Responsive Materials, EarlyView.
Polymer electrolytes exhibiting decoupled ionic transport from polymer chain segment motion have great potentials to enable simultaneous achievement of high ionic conductivity and robust mechanical properties at room temperature. This review provides a comprehensive examination of decoupled polymer electrolytes, covering their fundamental ion transport
