Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials
Advanced Materials Technologies, EarlyView.This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...

An Adiabatic Architecture for Linear Signal Processing [PDF]
Advances in Radio Science, 2005 Abstract. Using adiabatic CMOS logic instead of the more traditional static CMOS logic can lower the power consumption of a hardware design. However, the characteristic differences between adiabatic and static logic, such as a four-phase clock, have a far reaching influence on the design itself.

Advanced Optical Materials, EarlyView.Theoretical lessons are key for molecules presenting an inverted singlet‐triplet excited state (e.g. S1 and T1) energy difference. This perspective provides a snapshot of the role played by calculations in last years, not only to anticipate experimental findings but also for driving high‐throughput virtual screenings, as well as the main challenge to ...

QUBO formulations for training machine learning models
Scientific Reports, 2021 Training machine learning models on classical computers is usually a time and compute intensive process. With Moore’s law nearing its inevitable end and an ever-increasing demand for large-scale data analysis using machine learning, we must leverage non ...

Topological Line Defect Waveguide
Advanced Optical Materials, EarlyView.The work unveils the prevalence of topological modes across diverse photonic crystal platforms by experimentally demonstrating topological transport in conventional line‐defect waveguides. Interfacial waveguides are utilized as mode convertors to selectively excite topological states in photonic crystal systems.

Simultaneous Broadband Suppression of Homonuclear and Heteronuclear Couplings in 1H NMR Spectroscopy
ChemPhysChem, Volume 23, Issue 24, December 16, 2022., 2022 Ultra‐high resolution 1H NMR spectra are obtained by simultaneous broadband suppression of both homonuclear and heteronuclear scalar couplings, giving a fully pure shift 1H NMR spectrum containing chemical shift information only. The analysis of a range of fluorine‐ and phosphorus‐containing systems highlights how this method can be used to aid the ...
