Abstract Microinvertebrates in harsh environments often occupy the highest trophic levels and directly influence turnover of macroelements. However, investigation their body elemental composition is complicated due to low dry weight or sample size hindering application established methodological approaches. We present a new approach for estimation phosphorus (P) single multiple microinvertebrate species. As target model, we chose glacier tardigrades, which are among top consumers on...

This coupled two duoplasmatron sources and single sputter ion source provides ions hydrogen to gold. One these nuclear microbeam facility, utilizing beams micro- sub-micro sizes for materials research by use particle induced x-ray emission spectroscopy, gamma emission,...
Understanding the interaction between fusion plasma and plasma-facing materials (PFMs) is crucial for achieving optimal performance, safety, lifetime of devices. Relevant have been intensely studied to determine fuel retention composition co-deposited layers on PFMs by depth profile analysis using Laser-Induced Breakdown Spectroscopy (LIBS) Calibration-Free (CF)-LIBS. However, comparison containing a mixture different (seeding) gases LIBS, has not systematically. Consequently, aim this work...
In this study, novel flexible micro-scale humidity sensors were directly fabricated in graphene oxide (GO) and polyimide (PI) using ion beam writing without any further modifications, then successfully tested an atmospheric chamber. Two low fluences (3.75 × 1014 cm−2 5.625 cm−2) of carbon ions with energy 5 MeV used, structural changes the irradiated materials expected. The shape structure prepared micro-sensors studied scanning electron microscopy (SEM). compositional area characterized...
Different studies reveal the behaviour of Ta alloying to decrease deuterium retention in tungsten bulk materials aiming be used for nuclear fusion applications.

The conventional procedure for creating 3D microstructures in resists by ion beam lithography consists of two stages – exposure and developing. However, single stage manufacturing structures resist is also possible. Irradiation PMMA can cause it to shrink. This feature the polymer be used one-step three-dimensional microstructuring, which simplifies process. shrinkage film on a substrate has been extensively studied, while research free-standing not comprehensive. use allows creation...
Carbon beam writing was employed as a method for maskless production of microscale capacitors in both insulating graphene oxide (GO) and poly(methyl methacrylate) (PMMA) matrix.
