Not everything is ferromagnetic in high magnetic fields

High magnetic fields have a potential to modify the microscopic arrangement of magnetic moments because they overcome interactions existing in a zero field. Usually, high fields exceeding a certain critical value force the moments to align in the same direction as the field, leading to ferromagnetic arrangement. However, a recent study showed that this is not always the case. The experiments took place at the high-field magnet at HZB's neutron source BER II, which generates a constant magnetic field of up to 26 Tesla. This is about 500,000 times stronger than the Earth's magnetic field.

Diagnostics: Thermometer can be stretched and crumpled by water

A research team developed a flexible ionic conductor that is water-processable and thermal stable.

Using long-wavelength terahertz radiation to produce video with a high frame rate

A team of researchers at Durham University has found a way to use long-wavelength terahertz radiation to produce video with a high frame rate. In their paper published in the journal Physical Review Letters, the group describes their technique and its possible uses.

Physicists Discover Why This Bubble Solution Makes Monster Bubbles

Additives, like the main ingredient in a certain laxative, help thin soap films stretch into floating orbs.

New progress in turbulent combustion modeling: Filtered flamelet model

In turbulent combustion, the interaction between a strong nonlinear reaction source and turbulence leads to a broad spectrum of the spatio and temporal scales. From the modeling point of view, it is especially challenging to predict field statistics satisfactorily. Although there are different turbulent combustion models, e.g. the flamelet-like model, probability density function-like model, conditional moment closure model and eddy dissipation concept model, the bases of model closure have not been reasonably justified.

Next generation of greenhouses may be fully solar powered

Many greenhouses could become energy neutral by using see-through solar panels to harvest energy - primarily from the wavelengths of light that plants don't use for photosynthesis.

New multiplatform photon switch for application in quantum technology

An international team led by the Institute of Materials Science (ICMUV) of the University of Valencia has developed an optical (quantum) switch that modifies the emission properties of photons, the particles of electromagnetic radiation. The new device works with ultra-fast switching times and very low energy consumption and, in comparison to other designs, it can be implemented in a variety of semiconductor platforms and is of great application in current quantum technologies.

Magnetoelectric coupling in a paramagnetic ferroelectric crystal demonstrated

A team of researchers at Shenzhen University has demonstrated magnetoelectric coupling in a paramagnetic ferroelectric crystal. In their paper published in the journal Science, the group describes the ytterbium-based molecular magnetoelectric material they discovered and its possible uses. Ye Zhou and Su-Ting Han with Shenzhen University have published a Perspective piece describing the work in the same journal issue.

This Huge, Distant Galaxy Formed All Its Stars Super Fast

A massive galaxy in the early universe had already finished making stars by about 1.8 billion years after the Big Bang, challenging astronomers' current models.
