Appreciation towards Wenting ZhuBeauty of Science for providing the following description:

重现化学”是美丽科学与中国化学会的合作项目,共包含十五部影片和数百张精美图片,它是三年前“美丽化学”项目的续作。美丽科学将努力赋予这个项目长久的生命力。

Envisioning Chemistry is a collaboration project between Beauty of Science and Chinese Chemical Society, which contains fifteen short films and hundreds of beautiful pictures. It is also the sequel to the award-winning project Beautiful Chemistry launched 3 years ago. Building on the success of Beautiful Chemistry, which let millions of people discovered the unique beauty of chemistry. Beauty of Science will never stop the effort to create new works, and make this project young and vigorous all the time.

 

写给重现化学
To Envisioning Chemistry

重现化学并非为美而生,就像万物并非为美而生一样。生活中的确不容易见到重现化学里的这些情景,但不可否认它们也是世间朴素而又真实的存在,它是藏匿于真实世界的王国,有其独特的姿态与存在方式,需要我们的发现,也需要我们的欣赏。

于我而言,一切都是新的。七个月的拍摄过程,我在观看,也被引领着,走近崭新的天地:沉淀朴素的色彩与千姿百态,是飘荡在夜空中的精灵;纤细的银针散发着靡丽的光辉,乌黑的铅叶勾勒出原生的棱角;虚实闪烁的泡泡,熙熙攘攘地舞动着,变化着,宛若无息止的生命……重现,曾经对化学反应的一瞥成为反复实验与拍摄时长久的观望。在这过程中屈从与妥协,接纳并欣赏着每个事物原本的样貌,在已知的必然的反应发生中发现未知的偶然的惊喜。

这些微小的真实的造物,及其形态的微妙变化所产生的与自然界种种玄妙的关联,总能在不经意间,触发着我对大自然的崇敬,也牵引着我的遐想。

重现——对现实不加掩饰的呈现,仿佛才使我们有了更多对“为何”的提问与思考。

重现——在新的视野下,一切发现都没有边界,一切探索都不在于诉说一个答案。

重现,脑海中“熟悉”的知识被一次次带回“陌生”的原点,放下对美与丑,对与错固有的偏见,重新观看。

重现,是我初入化学世界时睁开双眼,开始迎接这里的第一缕阳光,现在,这阳光已渐入心灵深处,使我不断从梦中醒来,又进入到下一个梦境中。

Envisioning Chemistry tries to capture a purely objective record of chemical reactions. It grasps the images by using a macro lens and a microscope. In this way of viewing, we have a chance to look at tiny shapes and textures generated in this process, that allows me to experience the inexperienced things and perceive the unseen.

I was led to approaching a brand-new world. The various shapes of tiny creations in chemical reactions have an obvious connection with the nature world.

There is no end to discoveries that we can have if we seek them with our eyes open and in new perspectives. All these explorations are more than telling an answer.

气泡
Bubbling

当溶液中发生的化学反应产生气体时,气泡就会随之而生。影片共包括八个生成气体的反应。虽然气泡都是一样的形状,但聚焦其微观的局部,便展现出不同的意境。贝壳也能生成气泡吗?这部影片将给你答案。

Bubbles are generated when gases are produced by chemical reactions in solution. In this film, 8 gas-generating reactions were recorded with a macro lens to show the bubbling formation in great details.

▼贝壳中的碳酸钙与盐酸反应生成二氧化碳,Calcium carbonate reacted with hydrochloric acid generating carbon dioxide

▼锌粒在盐酸中生成氢气,Zinc reacted with hydrochloric acid generating hydrogen

▼碳酸氢钠在盐酸中生成二氧化碳,Sodium bicarbonate reacted with hydrochloric acid generating carbon dioxide

▼镁在盐酸中生成氢气,Magnesium reacted with hydrochloric acid generating hydrogen

 

电沉积
Electrodeposition

在电沉积过程中,溶液中的金属阳离子会沉积在与电源负极相连接的电极(阴极)表面,这一过程会产生奇特的金属结构。本影片利用显微摄影技术展示了铜、锡、锌、铅和银5种金属的电沉积过程,它或许将重新定义你对金属的印象。

During electrodeposition, metal cations in a solution get reduced at the electrode connected to the negative terminal of a power supply. Beautiful metal structures can be generated in this process. In this film, the electrodeposition processes of 5 metals, including copper, tin, zinc, lead, and silver, were recorded under a microscope.

▼电沉积生成的金属锌,Zinc generated from electrodeposition

▼电沉积生成的金属铅,Lead generated from electrodeposition

▼电沉积生成的金属铜,Copper generated from electrodeposition

▼电沉积生成的金属银,Silver generated from electrodeposition

▼电沉积生成的金属锡,Tin generated from electrodeposition

 

金属置换
Metal Displacement

海外用户可点击此处观看视频,click here to watch the video

活泼金属可以和较不活泼金属盐溶液发生置换反应。锌比银、铅、铜和锡活泼,因此在硝酸银、硝酸铅、硫酸铜和氯化锡溶液中加入一小块锌片时,锌片表面会生长出其它金属的微晶。此外,铜也可以置换出硝酸银中的银。该影片使用微距摄影和显微摄影拍摄。

A metal can displace a less reactive metal from its salt solution. Zinc is more reactive than silver, lead, copper, and tin. As a result, when pieces of zinc metal were dropped in the solutions of silver nitrate, lead(II) nitrate, copper(II) sulfate, and tin(II) chloride, microscopic metal crystals emerged on the surface of zinc and started to grow. In addition, copper was used for displaying silver as well. These growth processes were recorded with a macro lens and a microscope in this film.

▼锌在氯化锡溶液中置换出锡,Zinc displaced tin from tin chloride solution

▼锌在硝酸铅溶液中置换出铅,Zinc displaced lead from lead nitrate solution

▼锌在硫酸铜溶液中置换出铜,Zinc displaced copper from copper sulfate solution

▼铜在硝酸银溶液中置换出银,Copper displaced silver from silver nitrate solution

▼锌在硝酸银溶液中置换出银,Zinc displaced silver from silver nitrate solution
