Atomic insulators come in two varieties: so-called unobstructed and obstructed types. The former are common and now scanning tunnelling microscopy experiments provide evidence for the latter.

We propose an alternative approach to elementary particle detection: a plenoptic system combined with time-resolving single-photon avalanche diode array sensors leads to ultrafast three-dimensional high-resolution imaging in unsegmented scintillator.

Microfluidics experiments provide insights into transport and chemical processes in porous media, yet measuring evolving concentration profiles remains challenging. Here, the authors introduce a physics-based machine learning toolbox that integrates the non-intrusive reduced basis method, U-Net, and Convolutional Autoencoder to efficiently predict concentration profiles, enabling real-time analysis and tuning of experiments on the fly.

Shining intense laser pulses on an electron beam in an electron microscope corrects electron-optical spherical aberration, paving the way to using light to improve electron microscopy imaging.

An article in ACS Nano presents a large language model-powered autonomous zero-shot microscope for characterizing 2D materials.

Radiotherapy with charged particles is highly sensitive to uncertainties in their range. Now, radioactive ion beams offer increased precision and real-time imaging for tumour control while maintaining low toxicity to organs at risk.

Shaping the magnetic configuration in the power exhaust region brings major advantages to addressing the challenge of controlling the power exhaust in nuclear fusion. Power exhaust control in these alternative configurations is now demonstrated in the MAST-U nuclear fusion experiment, offering an increased ability to passively absorb disturbances.

Phonon dynamics of self-assembled two-dimensional nanoparticle crystals is resolved by liquid-phase transmission electron microscopy.

Photodetectors based on emerging semiconductors such as quantum dots and perovskites have been under development for over two decades, but the use of diverse characterization methods and set-ups make it increasingly difficult to compare device performance. A more standardized approach to external quantum efficiency characterization is now essential.
