Molecular dynamics insights into bubble nucleation of liquid sodium on hybrid wettability surfaces: Temperature dependence and scale-induced site inversion

Molecular dynamics simulations were performed to investigate the bubble nucleation characteristics of liquid sodium on hybrid-wettability surfaces composed of alternating hydrophilic and hydrophobic stripes. Wall temperature T wall and stripe width w were varied independently to...

Vibration characteristics analysis and vibration suppression of shaft system based on multivariate nonlinear factors

Shale-gas reciprocating-compressor shaft systems are subject to coupled bending-torsional vibration produced by alternating loads and interacting nonlinearities, which challenges reliable vibration prediction and safety-oriented design. This study proposes a unified multi-nonline...

Inhibition mechanism of OH/F doping on radiation-induced optical degradation of amorphous silica

Irradiation-induced formation of color centers in amorphous silica often deteriorates the optical performance of the material, thereby significantly affecting its long-term service performance. At present, the mechanism underlying the inhibition of color centers induced optical p...

Stage-specific nanotherapeutics for glaucoma target elevated IOP, impaired aqueous-humor outflow, RGC degeneration, and fibrotic inflammation during postoperative wound healing

Glaucoma is a chronic neurodegenerative disease in which elevated intraocular pressure (IOP), impaired aqueous-humor outflow, retinal ganglion cell (RGC) degeneration, and postoperative fibrosis may coexist or predominate at different stages. Conventional therapies are effective...

Experimental investigation and strength evaluation of steel-plate composite wall-to-wall L- and T-joints with different novel shear reinforcement

The steel-plate composite wall-to-wall joint configuration specified in current design codes is particularly susceptible to shear failure. Existing experimental studies have reached contradictory conclusions regarding whether shear reinforcement can enhance joint strength. The in...

Cascaded‐Gain‐Amplified Fiber Microcavity Laser With Attomolar Detection Limit

ABSTRACT Optical fiber microcavities have attracted considerable interest for their potential in developing multi‐color microlasers and high‐performance sensors. Owing to their high Q‐factor‐enhanced light‐matter interaction, fiber microcavity lasers have been extensively investi...

The Cambrian Magmatic Evolution in the Damara Belt, Namibia: Constraints from Garnet-Bearing Granites

Abstract Garnet is a petrogenetic key indicator, common in igneous and medium- to high-pressure metamorphic rocks. It provides valuable constraints for pressure–temperature–time paths in orogenic belts and offers insight into magma generation, evolution, and crystallization. To i...
