Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots
Advanced Materials, EarlyView.A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Air volume resonances and their influence on hall acoustics
Archives of Acoustics, 2014 The influence of resonances in a small rectangular music-hall on its reverberation characteristics was investigated. The length, width and height of the hall are 13.6 x 10.7 x 7 m, respectively.

Reverberation Time and Power Model in Indoor Wireless Scenarios [PDF]
Radioengineering, 2018 A novel, room-electromagnetics-theory-based model for reverberation time, path gain and Power Delay Profile (PDP) is proposed. Unlike the traditional models describing only the reflections, the new model takes not only reflections at boundaries, but also

On the equation for reverberation time in acoustics
The Journal of the Acoustical Society of America, 1990 A new derivation for the reverberation time equation is here proposed. From the accurate analysis of a model describing the acoustics of enclosed spaces in terms of a feedback system, a surprisingly easy and deep insight of the complex phenomenon of reverberation is readily obtained without any loss of formal rigor.

Acoustic analysis of a semi-anechoic chamber with intersection
بهداشت و ایمنی کار, 2014 Introduction: The previous studies have used fibrous absorbents usually in the form of cone-shaped wedges for making anechoic and semi-anechoic chambers which their design and construction have been costly and difficult. The present study aimed to design

Chiral Altermagnetic Magnetoelectrics
Advanced Materials, EarlyView.In this work, we introduce a previously unexplored class of magnetoelectric materials, which we term chiral altermagnetic magnetoelectrics, in which structural chirality and Néel‐vector‐driven polarization are intrinsically coupled in nonpolar altermagnetic systems.

Simulation Study on Detection and Localization of a Moving Target Under Reverberation in Deep Water
Journal of Marine Science and EngineeringDeep-water reverberation caused by multiple reflections from the seafloor and sea surface can affect the performance of active sonars. To detect a moving target under reverberation conditions, a reverberation suppression method using multipath Doppler ...

Water Reverberation Travel Time Analysis Acquired Using Multi-Depth Streamers
Terrestrial, Atmospheric and Oceanic Sciences, 2016 Ghost reflections and water reverberations are major and inevitable seismic noises in marine seismic exploration. More recently, new receiver deployment techniques at different sea depths for signal-to-noise ratio (SNR) enhancement are developing.
