针对一种新型磁性阴离子交换树脂(MIEX®)的再生工艺进行优化研究。探讨了不同再生方式对MIEX®性能恢复的影响,在最佳再生方式基础上,研究了再生液浓度及流量与MIEX®再生效果之间的关系,以及MIEX®的可再生次数。试验结果表明:MIEX®再生方式中以动态逆流再生效果最好,最佳再生液为质量分数10%的NaCl溶液,最佳流量为15 mL/min。随着再生次数不断增加,MIEX®处理效果小幅下降,当再生次数达到25次时,MIEX®性能明显下降,难以有效再生。

ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves

为了促进金沙江干热河谷区草业开发、畜牧业基地建设和生态农业发展,筛选出再生性强、产量水平高、水分利用效率高的人工牧草,我们于2005年研究了4个不同牧草的再生草产量、再生草生长速度以及再生草水分利用效率。结果表明,所有引进种二茬草的再生速度都比当地轮生狗尾草高。所有引进种再生草的产量都高于当地轮生狗尾草。斯伦春大翼豆、德梅纳罗克非洲狗尾草、贝斯莉斯克伏生臂形草等牧草再生草产量高,水分利用效率高,再生性强,是适于在金沙江干热河谷地区推广种植的节水型牧草。

Political Cycles, Electricity Policy, and Mexico's Economy
ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...

分析了pH对颗粒活性炭(GAC)吸附苯酚性能的影响。实验选择质量分数为1% NaOH溶液,采用微波辅助溶液再生的方法,对吸附苯酚的GAC进行再生研究,探讨实验因素对GAC再生效率的影响。实验结果表明:最佳的再生条件为微波功率520 W、再生时间1.5 min、NaOH再生辅助溶液用量10 mL,此时GAC再生效率为95.6%。在最佳再生条件下,经过6次再生后GAC的吸附能力依然很强。

Policy, Waste, and Power: Textile Dumping in Chile's Atacama Desert
ABSTRACT Globally, 87% of textile fibers end up incinerated or in landfills, with Chile bearing the brunt of this crisis. Every year, 39,000 tons of discarded clothing are illegally dumped in the Atacama Desert, turning it into a sacrifice zone for the Global North's waste economy.

ABSTRACT Managing diabetic wounds requires simultaneously addressing their infectious, oxidative, and regenerative impairments. To address this, this study integrates a piezoelectric BiOCl@CuSe heterojunction (PFM‐verified) into an injectable F127/HA hydrogel, creating an ultrasound‐responsive smart dressing.

再生水厂利用城市污水处理厂二级出水作为再生水的水源,采用二级曝气生物滤池+纤维球过滤工艺对污水处理厂二级出水进行处理,处理后出水作为再生水进行回用。由于来水水质的制约,严重影响了再生水厂的中水再生能力,通过改变再生水厂来水水源,将二级曝气生物滤池串联运行改为并联运行,提高了再生水厂的处理能力,降低再生水成本。
