Evaluating Biomass‐Derived Electrospun Electrodes Using Nonaqueous Redox Flow Cells
Batteries &Supercaps, Volume 9, Issue 6, June 2026.Electrospun electrodes, derived from lignin and polyacrylonitrile feedstocks, were synthesized and compared to a commercial binder‐free carbon paper. The electrochemical and fluid dynamic performance of all three electrodes was investigated in a diagnostic flow cell with a nonaqueous electrolyte. While the commercial electrode outperformed the in‐house

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of lightweight, high‐attenuation, and broadband carbon‐based electromagnetic wave absorbers is hindered by the intrinsic trade‐off between impedance matching and dielectric dissipation. Herein, we report a facile and scalable synthesis of N‐doped lignin‐derived interconnected porous carbon (Nx‐LIPC) via hydrogen‐bond self ...

Chip-Handling and Kraft Pulping.
JAPAN TAPPI JOURNAL, 1996 パルプ原材料の96%を占めるチップの現状と購入チップの受け入れ設備及び貯蔵施設に触れた後, KP蒸解反応と連続蒸解設備の改良について, 反応速度論の立場から解説した。脱リグニン反応速度と炭水化物の崩壊反応速度をチップ厚さの影響なども含め説明し, 時間, 温度, アルカリ濃度, 硫化度及びチップ厚さの5因子を入れた蒸解反応速度式をアルレニウスの式に基づいた実験式として紹介した。さらに蒸解の目的がパルプ成分である炭水化物をできるだけ多く残し, リグニンの残留量を少なくすることから.反応が選択的になり得るための望ましい蒸解反応条件を探るために蒸解反応の選択性とシミュレーションによる最適化を解説した。すなわち, 得られた実験式に各種蒸解条件を入れて数値計算し ...
