日本語
ヒト尿から高純度アンモニウムを回収しつつ、水素を同時生産する膜フリープラットフォームを開発。固定化ウレアーゼビーズとKCoHCF電極により、尿素の98%以上を加水分解し、アンモニウムを99.9%の選択性で回収。有機物の82%を除去し、正味エネルギー利得（-0.47 kWh/kg-N）を達成。物理情報に基づく劣化モデルでシステム寿命を高精度に予測し、自律運用を可能にする。
English
This platform recovers high-purity ammonium from human urine while co-producing hydrogen, powered by its own organics. It achieves >98% urea hydrolysis, ~90% ammonium capture with 99.9% selectivity, and 82% organic removal, with a net energy gain (-0.47 kWh/kg-N). A physics-informed degradation model predicts system lifetime accurately, enabling autonomous operation.

📄 Abstract（原文）
<title>Abstract</title> <p> Conventional sanitation runs a self‑defeating loop: energy is spent destroying nitrogen in wastewater while industry expends more to fix it anew from air. Human urine carries most of that nitrogen, and here we turn this disposal cost into a resource. Our durable, membrane‑free platform recovers high‑purity ammonium from raw, undiluted urine and co‑produces hydrogen, powered by its own organics. Immobilized urease beads hydrolyze >98% of urea, and a record-surface-area KCoHCF electrode selectively captures ~90% of ammonium at 99.9% selectivity and a recovery rate of ~1,100 g-N.m <sup>-2</sup> .d <sup>-1</sup> , rejecting Na <sup>+</sup> by 2,300-fold and K <sup>+</sup> by 10-fold while retaining 93% capacity over 1,000 cycles through breathing effect. The platform simultaneously removes 82% of organic matter and operates with a net energy gain (−0.47 kWh kg <sup>-1</sup> -N), enabling profitable operation at medium- and large-campus scales. A physics-informed degradation model accurately predicts system lifetime without large training datasets, outperforming existing approaches and enabling autonomous long-term operation. </p>
