A Self-Powered Photodetector Based on an Ambient-Air-Processed Cs3Bi2I9 Heterojunction for Optical Wireless Communication

The evolution toward a genuinely intelligent Internet of Things envisions future optical wireless networks anchored by extensive terminal nodes to facilitate pervasive sensing and communication. This vision places unprecedented demands on the underlying hardware, particularly in...

The coefficient 1/log 2 in an n^2 log n lower bound for Hilbert numbers via two-axis recursive bifurcation

This research compendium accompanies the preprint “The coefficient 1/log 2 in an n^2 log n lower bound for Hilbert numbers via two-axis recursive bifurcation.” For real planar polynomial vector fields of degree at most n, the paper proves that liminf H(n)/(n^2 log n) is at least...

Simultaneously Improving the Selectivity and Stability of HZSM-5 Zeolite by NaOH Treatment in Aqueous Ethanol-to-Propylene Reactions

Mesoporous nanoscale HZSM-5 zeolites were prepared by alkali treatment and characterized by XRD, SEM, NMR, ICP-OES, N2 adsorption/desorption, NH3-TPD, Py-IR, and TG techniques. The effects of NaOH concentration on pore structure, acidity, and catalytic performance of nanoscale HZ...

Enhancing the sensitivity of emulsion stability monitoring: A study based on precursor signals from multiple light scattering analysis

Abstract To accurately identify early destabilization signals in emulsions, this study employed multiple light scattering (MLS) technology combined with microscopic observation, particle size analysis and long‐term macroscopic stability tests to perform a multi‐scale evaluation o...

Version 1.4.0 of the research materials for “Neutral Entry–Exit Cycles with Quadratic Grazing: Uniform Return Reduction and Local Two-Parameter Bifurcations” (arXiv:2607.27464). The primary record file is neutral-entry-exit-arxiv.pdf (43 pages, 3 figures) and is selected for dire...

Strength enhancement and microstructural evolutions of dredged slurry stabilized with waste-modified composite binder

Dredged slurry with high water content and low permeability is prone to drainage clogging during vacuum preloading, limiting its direct use in land reclamation and typically requiring cement-based treatment. To explore a lower-carbon alternative to conventional treatment, this st...
