The Physics of Explosion Physik der Explosion
CHIMIA, 2003 Some interesting physical aspects of chemical explosions are compiled. An explosion is understood as a fast release of energy. There are many types of explosion, including a deflagration as a pressure-controlled explosion and a detonation as an ...

Advanced Science, EarlyView.Mixed‐cation MAx${\rm MA}_x$ FA1−x${\rm FA}_{1-x}$ PbI3${\rm PbI}_3$ perovskite crystals reveal multiple discrete electron and hole spin subensembles associated with distinct localization environments. Optically detected magnetic resonance combined with resonant spin inertia uncovers carriers spin relaxation times reaching 2 ms and identifies nuclear ...

Advanced Electronic Materials, EarlyView.A non‐destructive, quantitative approach has been developed to explore the nanoscale dynamics of TaOx‐based memristive devices. The utilization of nano‐X‐ray fluorescence analysis enables the direct probing of spatially resolved elemental distributions, including those present in buried layers, that are critical for the resistive switching.

Modellierung und Analyse komplexer Alltagsphänomene
Herausforderung Lehrer*innenbildung, 2018 Im Zuge der wachsenden Digitalisierung von allen Aspekten der Schule wandeln sich auch die Anforderungen an die Unterrichtsgestaltung. Auch angehende Physiklehrkräfte sollten schon in der ersten Ausbildungsphase auf diese Anforderungen vorbereitet werden.

Advanced Electronic Materials, EarlyView.This work presents inkjet‐printed MHP photodetectors and optical filters. Three precursor inks enable bandgaps from 1.6–3.1 eV, covering the visible spectrum. Combining detector and filter produces a fully printed, dispersion‐free optical spectrometer with precisely tunable spectral selectivity and a minimum spectral bandwidth of 30 nm.

Die Relativität des Raumes und der Zeit. Stürzte Einstein das Newtonsche Weltbild?
Revista de Filosofia, 2005 Die weit verbreitete Auffassung, Einstein habe das Newtonsche Weltbild gestürzt, gründet in der unberechtigten Gleichsetzung der von Newton begründeten physikalischen Theorie Mechanik mit der philosophischen Rezeption dieser Naturwissenschaft im ...

Teorema de Ehrenfest e o limite clássico da mecânica quântica
Revista Brasileira de Ensino de FísicaApresentamos argumentos sustentando que o teorema de Ehrenfest não é formal e conceitualmente adequado para conectar a mecânica quântica à mecãnica clássica.

Atomic Scale Control of Thermal Conductivity in LaMnO3/SrMnO3 Superlattices
Advanced Electronic Materials, EarlyView.Interface‐dominated cross‐plane thermal transport in [(LaMnO3)m/(SrMnO3)n]10 superlattices can be controlled by the octahedral rotation/tilt angle φOOR of the MnO6 octahedra, which as well is controlled by the “m/n” ratio. ABSTRACT We report atomic scale structure and phonon thermal transport in (LaMnO3)m/(SrMnO3)n/SrTiO3(100) superlattices (LMO/SMO ...
