Deep Volumetric Super‐Resolution Imaging in Thick Biological Specimens With Sparse Scanning SIM
Advanced Science, Volume 13, Issue 25, 4 May 2026.Sparse scanning structured illumination microscopy (SS‐SIM) extends the axial depth in super‐resolution fluorescence imaging by combining rapid laser scanning, pixel‐addressed intensity modulation, and sCMOS camera detection. SS‐SIM yields 1.6× lateral and 1.7× axial resolution gains over wide‐field microscopy and enables imaging through 300–600 µm ...

Batteries &Supercaps, Volume 9, Issue 5, May 2026.Lithium‐ion batteries used in space applications are exposed to extreme conditions, including radiation, vacuum, wide temperature fluctuations, and long storage times, all of which accelerate degradation. This review article summarizes the main degradation mechanisms affecting battery performance in space environments, including capacity fade ...

Oikos, Volume 2026, Issue 5, May 2026.Tree species diversity is known to affect tree growth and leaf traits, which in turn can influence various ecosystem processes. However, the reported direction of these tree diversity effects is inconsistent, indicating that their outcomes depend strongly on ecological context.

Surface and Interface Analysis, Volume 58, Issue 5, Page 326-333, May 2026.ABSTRACT In the present study, we have analyzed the growth profile of ruthenium (Ru) thin films, deposited using pulsed direct current (DC) magnetron sputtering technique, by varying the sputtering voltages in the range of 150–420 V. The grazing incidence X‐ray reflectivity (GIXRR), time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS), and atomic ...

Electrothermal Twisted and Coiled Polymer Artificial Muscles and Their Applications in Soft Robotics
Small Structures, Volume 7, Issue 5, May 2026.Researchers develop a PE@SPN electrothermal polymer artificial muscle with a parallel‐stranded spiral structure. A temperature self‐sensing‐driven hierarchical closed‐loop fractional order PID (FOPID) control scheme is adopted. A rehabilitation manipulator was designed, and subsequently, a series of experiments are conducted to test the performance of ...

Constraining Electron‐Impact Ionization of O2 Through UV Aurora Observations at Ganymede
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract While photoionization rates of Ganymede's O2 ${\mathrm{O}}_{2}$ dominated atmosphere are well constrained, the contribution of electron‐impact ionization is rather uncertain. Previous quantitative estimates have relied on assumptions about densities and energy distributions of precipitating electrons, or on rare spacecraft measurements that ...
