This article explores light-trapping enhancement in newly discovered graded photonic super-crystals (GPSCs) with dual periodicity and dual basis.

Article develops an allometric model capable of fitting the initial phase of the COVID-19 pandemic and predicting the propagation of the illness for up to 100 days.

Article describes an experiment in which a hot-electron-enabled route to controlling light with dissipative loss compensation in semiconductor quantum light emitters has been realized for tunable quantum optoelectronic devices via a two-species plasmon system.

This article studies low-energy interactions of positrons with xenon experimentally and theoretically. Results are compared with previous literature.

This article presents an accurate first-principles study of the electronic structure and absorption spectrum of six elemental metals (aluminium, gold, silver, copper, palladium, platinum) using density functional theory in an all-electron full-potential framework.

Article presents how to enhance ice contrast in the visible spectrum by using ice birefringence and polarized light reflection. The method can be used for both visual inspection and automatic ice detection systems.

This article is part of a Focus Issue on the topic of Rubin LSST Survey Strategy Optimization. The motivation, history, and decision-making process of the observing strategy optimization are detailed, giving context to the science-driven proposals and recommendations for the survey strategy included in this Focus Issue.

This article describes a method of measuring cortisol levels. It presents a metal-enhanced fluorescence assay based on a displacement of a dye labeled BSA-cortisol conjugate from the immune complex immobilized on the golden islands by free cortisol.

Article develops a planar model for an artificially structured boundary that may provide magnetic confinement of nonmagnetically trapped plasma particles.

This article presents a critical comparison of continuum diffuse-layer models that can be coupled to an atomistic first-principles description of the charged metal surface in order to account for the electrolyte screening at electrified interfaces.

Article reporting the change in the transient absorption characteristics of monolayer MoS2 and the modified PL emission characteristics in a monolayer MoS2–GaN (0001) heterostructure due to the coupling of carriers with the phonon modes and the energy exchange at the interface. The results demonstrate the relevance of interface coupling between the semiconductors for the development of optical and electronic applications.

Article describes how titanium and nickel alloys are used in the creation of components exposed to harsh and variable operating conditions. The authors state that a search is underway for cutting parameters that will minimize the vibration while meeting the quality requirements.
