Neutrinos in Stochastic Media: From Sun to Core-Collapse Supernovae

, 2001
Recent work on neutrino propagation in stochastic media and its implications for the Sun and core-collapse supernovae are reviewed. It is shown that recent results from Sudbury Neutrino Observatory and SuperKamiokande combined with a best global fit ...

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

Advanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Solution‐Processable and Ambient‐Stable Highly Conductive p‐Type Polymers Derived from Dihydropyrazine and Ethylenedioxythiophene

Advanced Functional Materials, EarlyView.
This work presents π–conjugated polymers based on dihydropyrazine (DHP) and ethylenedioxythiophene (EDOT), developed to produce highly conductive, flexible films for printed electronics. By optimizing the DHP and EDOT ratio, strong and compact π–π stacking is achieved, resulting in polymer films with conductivities up to 1700 S cm−1 under ambient ...

Interfacial Interaction‐Mediated Regulation of Metal Oxidation States for Enhanced CO2 Reduction

Advanced Functional Materials, EarlyView.
A hybrid strategy is employed to optimize bismuth–oxygen interactions, precisely regulating interfacial bismuth–oxygen bonds during topochemical synthesis. This leads to vanadium oxynitride‐bismuth catalyst exhibiting high Faradaic efficiency and durability for formate production, attributed to enhanced reaction thermodynamics and kinetics.

Plasma and solar physics. The solar flare phenomenon

Le Journal de Physique Colloques, 1979
The main topics of solar physics to which plasma physics is relevant are briefly presented. The solar flare phenomenon is described and some present theories concerning the preflare state and flare triggering reviewed, namely the theory based on the existence of a turning point in the set of possible preflare equilibria and the theory based on an ...
