title: Mechanism of Polyethylene Glycol Assisted Crystallization of Magnesium Carbonate trihydrate research
title: 聚乙二醇辅助三水碳酸镁结晶过程机理研究

description: To enhance the preparation of high-aspect-ratio magnesium carbonate trihydrate (MgCO₃·3H₂O) via polyethylene glycol (PEG)-assisted coprecipitation, MgCO₃·3H₂O was synthesized and characterized by XRD, SEM, TG-DSC, FTIR, and particle size analysis. The effect of PEG concentration on the aspect ratio was investigated, and in situ 2D imaging was employed to explore the growth mechanism over a 240 min reaction under the optimal PEG addition. The results indicated that the aspect ratio decreased with increasing PEG content. At 0.2 wt% PEG, rod-like crystals with an aspect ratio of 11.53 and an average length of 46.69 μm were obtained. In situ imaging revealed initial nucleation at approximately 15 min, enabling real-time monitoring of crystal evolution. Crystals up to 167.24 μm in length were formed, with a Mg2+ conversion rate of about 91%. The transformation between MgCO₃·3H₂O and Mg₅(CO₃)₄(OH)₂·5H₂O via dissolution–recrystallization was observed during prolonged reaction. This study provides a novel analytical approach for investigating MgCO₃·3H₂O and offers a practical reference for synthesizing high-aspect-ratio crystals using PEG.

title: The Neutron Lifetime Puzzle in G-MaTT: Environmental Torsion and Topological Decay

description: Abstract

The neutron lifetime discrepancy between beam (τ_beam ≈ 888.0 ± 2.0 s) and bottle (τ_bottle ≈ 879.5 ± 0.8 s) methods—Δτ ≈ 8.5 s at 4.4σ—remains unresolved despite refinements in Standard Model calculations and experimental systematics. In Generalized Mass as Twisted Time (G-MaTT), the neutron is a coherent braid composite in the torsion field ℳ_μ, with decay as topological reconfiguration modulated by the TUT (Twist-UnTwist) weight. We show the discrepancy arises from environmental ℳ_μ coupling: bottle walls induce desynchronization, suppressing decay rate by ~1%. Deriving Γ = Γ_0 · 𝒲_TUT[ℳ_env], we predict Δτ/τ ≈ - (β' N_corr δℳ²)/2 ≈ -0.009 (8.4 s), with β' ≈ 1.2 from nuclear coherence and δℳ² ≈ 0.004 from TUT. Mass renormalization via collective modes (λ ≈ 10 nm) yields η ≈ 10^{-3}, consistent with 0.2% ΔQ shift. Predictions include material dependence (Cd enhancement 1.5–2×), distance oscillations (Λ ≈ 0.5 mm), and hysteresis—testable at J-PARC BL3 (2026). This resolves the puzzle geometrically, linking to cadmium interferometry anomalies and bound neutron stability.
