Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications
Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

Abstract For over 60 years, an approximation involving spherical geopotentials has underlain the representation of gravity in global numerical models of Earth's atmosphere and oceans. This article explores how departures from sphericity can be allowed by assuming spheroidal geopotentials instead. A route to more accurate model formulation is indicated,

Photon entanglement detection by a single atom
We use a single trapped ^40 Ca ^+ ion as a resonant, polarization-sensitive absorber to detect and characterize the entanglement of tunable narrowband photon pairs from a spontaneous parametric down-conversion source.

Conductive fiber membranes can be used as strain sensor and self‐powered sensor for dual‐mode human motion detection. The strain sensor boasts a wide operating range (0.5%‐195%) and excellent sensitivity (gauge factor (GF) up to 54 at 50% strain). The STENG has high energy harvesting efficiency with an output voltage of 115 V and maximum power density ...

A spray‐drying‐based synthesis is presented for colloidally stable Co and ZnCo ferrite nanoparticles (NPs) with adjustable Curie temperatures. Combining these NPs in a second spray‐drying step creates supraparticles with tunable induction heating plateaus, achievable by adjusting the AC magnetic field.

Opportunities and Limitations in Recycling Fossil Polymers from Textiles
The recovery and recycling of textile waste is becoming urgent since textiles are generating more and more waste. In one year, about 92 million tons of textile waste are produced and the fashion industry accounts for 58 million tons of plastic waste per ...

Application of Standard HSQC‐ME Pulse Sequence on Benchtop NMR Devices for Quantitative Applications
The heteronuclear single quantum correlation (HSQC) NMR method is widely used for the structural characterization of complex mixtures. In this study, the application range of multiplicity‐enhanced HSQC (HSQC‐ME) spectroscopy was broadened to quantitative analysis on low‐field NMR devices with standard measurement possibilities.
