On-demand engineerable visible spectrum by fine control of electrochemical reactions

National Science Review 2024年第3期11卷 239-249页

Tunability of optical performance is one of the key technologies for adaptive optoelectronic applications,such as camouflage clothing, displays, and infrared shielding. High-precision spectral tunability is of great importance for some special applications with on-demand adaptability but remains challenging. Here we demonstrate a galvanostatic control strategy to achieve this goal, relying on the finding of the quantitative correlation between optical properties and electrochemical reactions within materials. An electrochromic electro-optical efficiency index is established to optically fingerprint and precisely identify electrochemical redox reactions in the electrochromic device. Consequently, the charge-transfer process during galvanostatic electrochemical reaction can be quantitatively regulated, permitting precise control over the final optical performance and on-demand adaptability of electrochromic devices as evidenced by an ultralow deviation of <3.0%. These findings not only provide opportunities for future adaptive optoelectronic applications with strict demand on precise spectral tunability but also will promote in situ quantitative research in a wide range of spectroelectrochemistry, electrochemical energy storage, electrocatalysis, and material chemistry.

故宫博物院"金漆花鸟琴"为清宫旧藏古琴,与其它传世古琴不同,它的漆地表面有用金粉和颜料描绘的龙纹、花鸟、山石等纹饰,琴上龙纹图案,琴侧的花菱纹,琴面和琴背的花卉等,均与传统中国漆器上的纹饰存在明显差别,具有日本纹饰的显著特征。从髹漆工艺看,琴上纹饰和花鸟图案,创作技法上采用日本平莳绘、高莳绘、色粉莳绘等不同莳绘的髹漆技法。考察日本古琴发展及中日贸易关系,江户时代(1603—1867年)后期,古琴在日本颇为流行,并一度在日本成为一种时尚,古琴文化的发展在日本达到鼎盛时期。故宫博物院收藏的这张"金漆花鸟琴",具有江户时期日本莳绘漆器的艺术风格,应该就是受中国古琴在日本盛行风气影响的产物,它是日本江户时期制作的莳绘工艺品,而后流入中国,并为宫廷所收藏。此琴进入清宫的时间,当在乾隆末期前后。

Tetraploid　induced　by　physical　and　chemical　methods　in　Jinjiang　oyster（Crassostrea　rivularis）

Acta Oceanologica Sinica 1994年第2期13卷 275-283页

作者： Rong Shoubai, Shi Shumei,Mc qirong, liu Shaeqiong,Liang Ze,Zhao Xiuzhu, Tong Wangdong Li Shouwu and Li Yimin

In order to induce tetraploid into Jinjiang oyster (Crassostrea rivularis), embryos were treated with physical (cold or heat shock) and chemical (chlorpromazinum or traditional Chinese medicine)methods in the first 3 min before the cleavage of zygotes or at the onset of the first cleavage of one or two eggs. Measurements show that the induction rates of tetraploid in the embryos inspected are 28%, 30%, 28. 4% and 35. 8% for heat-shock (39℃, 3 min),cold-shock (10℃, 3min),chlorpromazinum (0. 375 mg/dm3, 10 min) and traditional Chinese medicine (50 g/dm3 )extract (57 cm3, 10 min),respectively. The tetraploid induction rate in the larvae treated with traditional Chinese medicine is 32. 5%.It is evident that the induction rate of tetraploid in embryos insected at an early stage is the most remarkable when treated. with traditional Chinese medicine.

本文利用2012年的投入产出表与行业数据,分析我国出口贸易的水足迹,并模拟分析优化我国出口贸易结构的节水、环保与经济效益。研究表明,蓝色水与灰色水密集型行业出口贸易在我国出口贸易中的总体比重较低,这有利于节约我国水资源与保护水环境,但部分蓝色水与灰色水密集型行业产品出口所占的比重仍较大,需要进一步优化出口贸易结构。2012年,我国出口贸易的水足迹高达1540亿立方米,主要集中于制造业与农产品及其加工业。在兼顾减少水足迹与提高贸易增加值情况下,优化我国出口贸易结构,不但能够获得良好的"节水"与"环保"效益,而且还能够取得较大的经济效益。
