Establishing two-stage interaction between fly ash and NaOH by X-ray and infrared analyses

Bhagwanjee JHA,Nevin KOSHY,Devendra Narain SINGH

《环境科学与工程前沿（英文）》 2015年第9卷第2期页码 216-221 doi: 10.1007/s11783-014-0630-8

摘要： The interaction of the fly ash and NaOH, in an open reflux hydrothermal system at 100°C, has been explored by several researchers and formation of fly ash zeolites has been confirmed based on the X-ray diffraction analysis of the residues. However, this method does not reveal much about the characteristic transitions (viz. elemental, electro-negativity and cation exchange capacity) of the residues. In this situation, resorting to Fourier transform-infrared radiation (FT-IR) spectroscopy on the residues obtained from two-stage hydrothermal treatment process, described in this manuscript, appears to be a novel idea to establish transitions in chemical bonds (viz., -Si-OH-Al-, OH-Na, OH-Al-), crystallinity and cation exchange capacity of these residues. Based on extensive studies, it has been demonstrated that FT-IR spectroscopy is extremely useful for 1) detection of chemical bonds in the residues, 2) evaluation of zeolites in the residues and 3) also establishing the superiority of the two-stage interaction of the fly ash with NaOH for synthesizing better fly ash zeolites (viz., Na-P1 and Hydroxysodalte) as compared to those obtained from the conventional single-stage treatment of the fly ash.

Al-NaOH复合液态金属——一种具有热和气动特性且快速响应的水触发材料 Article

袁博, 孙旭阳, 刘静

《工程（英文）》 2020年第6卷第12期页码 1454-1462 doi: 10.1016/j.eng.2019.08.020

摘要：本研究提出并证明了一种基于Al-NaOH复合共晶镓-铟（eGaIn）合金的新型水触发材料，该材料具有快速响应性和可变形性。并据此设计了双层结构的智能绷带，其内部填充了Al-NaOH复合eGaIn，而BiInSn则作为外部支撑材料。同时，研究还使用Al-NaOH复合eGaIn制作了水触发球形机器人的原型，该原型在特定的外部刺激下实现了滚动和弹跳行为。
