Advanced Science, EarlyView.This work presents a magnetic‐bearing acoustic resonator that overcomes the thermodynamics limit of sound absorption. By introducing tunable negative stiffness, it achieves broadband low‐frequency absorption within a compact cavity, far exceeding the performance achievable by classic mass‐tuned designs.

Advanced Intelligent Discovery, EarlyView.In this study we employed support vector regressor and quantum support vector regressor to predict the hydrogen storage capacity of metal–organic frameworks using structural and physicochemical descriptors. This study presents a comparative analysis of classical support vector regression (SVR) and quantum support vector regression (QSVR) in predicting ...

Programmable Flocks: Hierarchical Swarm Control via Dynamic Parameter Injection
Advanced Intelligent Systems, EarlyView.We present a method for the control of robot swarms which allows the shaping and the translation of patterns of simple robots (“smart particles”), using two types of devices. These two types represent a hierarchy: a larger group of simple, oblivious robots (which we call the workers) that is governed by simple local attraction forces and a smaller ...

Prediction of Cyclic O6 Molecules Stabilized by Helium under Pressure
Advanced ScienceOxygen usually exists in the form of diatomic molecules at ambient conditions. At high pressure, it undergoes a series of phase transitions from diatomic O2 to O8 cluster and ultimately dissociates into a polymeric O4 spiral chain structure. Intriguingly,

Accurate and general model to predict molar entropy for diatomic molecules
South African Journal of Chemical Engineering, 2020 We present an accurate and a general model to predict the molar entropy of gaseous diatomic molecule substances. The proposed model is derived from the use of the partition function and shows an excellent agreements with experimental data in a wide range

King-Plot Analysis of Isotope Shifts in Simple Diatomic Molecules
Physical Review X, 2023 We demonstrate that the isotope shift in isotopomers of diatomic molecules, where the nucleus of one of its constituent atoms is replaced by another isotope, can be expressed as the sum of a field shift and a mass shift similar to the atomic case.
