Scaling‐Up of Structural Superlubricity: Challenges and Opportunities
At increasing length‐scales, structural superlubricity (SSL) faces challenges from physical and chemical energy dissipation pathways. This study reviews recent experimental and theoretical progress on these challenges facing the scaling‐up of SSL, as well as perspectives on future directions for realizing and manipulating macroscale superlubricity ...

Using nearly 230,000 red clump stars selected from LAMOST and Gaia, we conduct a comprehensive analysis of the stellar age–velocity dispersion relations (AVRs) for various disk populations, within 5.0 ≤ R ≤ 15.0 kpc and ∣ Z ∣ ≤ 3.0 kpc.

On the instability of thick accretion disks
A general method, based on a variational principle, is developed for the study of adiabatic oscillations in a gas cloud with negligible self-gravity, rotating in an external gravitational field. Second order virial equations are obtained. As an example, the formalism is applied to disk models with an equation of state pproportionalrho/sup 4/3/; such ...

All‐Cellulose‐Based Photonic Glitters
Uniform, disc‐shaped photonic CNC glitters with adjustable structural colors and diameters are fabricated on hydrophilic ethyl cellulose films using electrospray deposition. By employing patterned ethyl cellulose films with pre‐designed hydrophilic regions, photonic patterns can be created with these all‐cellulose‐based glitters, demonstrating their ...

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery
The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.
