Recognition at MNE 2024 Micrograph Contest
The MNE conference is the flagship event of the International Society for Micro- and Nanotechnology (iMNEs). The research fields covered by the MNE conferences have consistently driven advancements in the development of smaller and smaller structures. To emphasize the significance of micrographs in this field, the conference features a micrograph contest, sponsored and hosted by Zyvex Labs. Entries are judged based on both their technological relevance and artistic merit.
This year, Peng Qi from the X-ray Nano Optics group, LXN, CPS, earned third place and an honorable mention for his two submitted images.
Novel Photoresist Chemistry Enables Lithography Approaching Angstrom-Scale Resolution
Photoresist materials are crucial in the manufacturing of computer chips, where the circuits are initially printed in the photoresist using photolithography. As the demand for smaller and more precise circuitry in computer chips grows, photoresists must resolve features with smaller sizes and higher density. One of the factors determining the ultimate resolution in lithography is the molecular size/mass of the photoresists.

Apochromatic X-ray focusing
A team of scientists from the Paul Scherrer Institut, the University of Basel and DESY have demonstrated the first-ever realization of apochromatic X-ray focusing using a tailored combination of a refractive lens and a Fresnel zone plate. This innovative approach enables the correction of the chromatic aberration suffered by both refractive and diffractive lenses over a wide range of X-ray energies. This groundbreaking development in X-ray optics have been just published in the scientific journal Light: Science & Applications.

Dancing molecules
When cycloalkanes are enclosed in a nanometer-sized pore, they adapt their shape - similar to the induced fit concept described in #biochemistry. The molecules do not all behave in the same way and surprisingly start to move when there is a lack of space at 5K.

Light-Induced Magnetization at the Nanoscale
Targeted manipulations of an atom's magnetic moment are tricky, as the charge currents used for this process are extremely difficult to control . Now, a consortium of collaborators in Germany, Switzerland, Slovenia and Italy reports on a solution to this problem in the cover page article of Physic Review Letters 128, Vol. 15. As it appears, the magnetization of an atomic gas can be altered by high-power lasers using a patterned wave front. The method is promising for studying and manipulating the magnetic properties of matter at the nanoscale.
