Nobel Laureates in Chemistry said Chemistry is very interesting

By Xuefei Chen Axelsson

STOCKHOLM, Oct. 5(Greenpost)–Nobel Laureate Fraser Stoddart said that’s what driven him through chemistry, its wonderful ability to express yourself in an artisitic form.

 

J. Fraser Stoddart’s wife died twelve years ago so he first shared the news with his two daughters.

He said he was shocked and his students were overwhelmed. He felt glad that Sauvage and Feringa won the prize together with him.

Feringa said he will use the money for further research because it was the cooperation of many researchers.

BF: Ja, of course. If you look at the cells in our body or the functioning of the organism, it is flabbergasting.  It is fantastic to see how this intricate machinery works. And when I’m taking about motors, as we focus on motors, if you look at the essential functions in the cell, like cell division, like transport, like making your muscles move, bacteria that go to food or [unclear …] it’s all controlled by molecular motors, and so the biological motors, and the biological machinery, is so crucial to all these functions. And of course we get great inspiration from that, while we as chemists are extremely good in building all kinds of materials, and that is what intrigued me. And there is where we look at mother nature, but of course we have to build it more or less from scratch because many of the systems that mother nature uses we cannot use in our nanomachinery, because they are soft materials that are not very stable that only function properly in the complex cell environment etc. So that is the reason that we build these machines. And compare it to a flying machine. We don’t build a Boeing after a pigeon. A pigeon flies perfectly, the bird flies, ja, but the Boeing is not the same materials, it has not the same flying principle, but it works perfectly to transport 3-400 people across the ocean.

AS: That’s perfect. And people often make the comparison with Lego. They say you’re building with the tiniest Lego.

BF: Absolutely. So we use molecules as a kind of Lego kit, ja. And so we have access to this unlimited number of molecules and we use them to build the new materials, the drugs of the future, and in this case also the nanomachinery and the smart materials of the future. And yes, I feel often, and me and my students and the team, and I’m sure that it’s the same for the other teams of Stoddart and Sauvage, we feel sometimes like kids playing with these molecules and seeing what are the possibilities to build, like with Lego. As a kid you had fun to build new kinds of castles, and that is actually what we are doing. And then hopefully, and this is our main goal of course, to build in all kinds of new functions. And in this case the function of transport, motion, machinery.

AS: That’s a fantastic, inspirational message for the next generation of scientists. Just go out there and express yourself and have fun.

汉松说,他们开发了世界上最小的机器,就是在肉眼看不见的分子那么大的层面赋予了可控的运动,如果给点儿能量就可以完成任务。

“瑞典皇家科学院决定授予法国斯特拉斯堡大学教授让.皮埃尔.索瓦滋,英国爱丁堡出生美国西南大学教授弗雷泽. 斯铎达特和荷兰格罗宁根大学教授2016年诺贝尔化学奖。他们获奖的理由是,对分子机器的设计与合成。”

thumb_dsc_3337_1024诺贝尔化学奖委员会主席林泽教授在接受北欧绿色邮报网时说,三位科学家的巨大贡献就在于他们在分子那么大的范围内开发了可以移动的机器,这样,人们就有可能根据人类的意愿让它执行任务了。当然,实践应用还没有开始,现在只是刚刚开始,但是,有可能在生物医学领域发挥作用。

根据诺贝尔奖委员会的资料,著名诺贝尔奖获得者费尔曼在50年代就曾经设想畅谈是否可以发展比手要小得多得多的机器手。没想到他的畅想和疑问在1983年有所突破。当然和他想的不太完全一样。

笔者家中有一本写费尔曼的小书,是他学生写的,非常幽默风趣。但是,确实写出了一个非常专业的基础研究科学家的风范。他给学生不留什么作业,但是,积极鼓励他们做他们自己感兴趣的有创意的项目。笔者的博士老公推荐我以及一些中国学者要读这本书,这对我们的科研的态度和作风可能都有启发。

书归正传,1983年,法国科学家让.皮埃尔.索维奇采取了分子机器设计的第一步。他成功地将两个环形分子连在了一起形成一个链。通常分子是有很强的纽带连载一起,但是,在分子链中它们的连结是自由的机械连接。一个机器为了能够完成一项任务,它必须有可以自由活动的几个部分相互连接。而这两个互相套在一起的圆环正好符合这个要求。

1991年,斯铎达特采取了第二个步骤。他开发了一个旋转轴,Rotaxane.他把一个分子环套到一个很细的分子轴上,冰展示该分子环能够沿着周活动。同时,他还开发了一个分子举重设备,一个分子肌肉和一个分子基础上的计算机芯片。

1999年,费令佳成为开发一个分子发动机的第一人。他获得一个分子叶片在同一方向不停地运转。使用分子摩托,他开发出一个比摩托本身大一万倍的玻璃圆柱体,同时,也设计了一个纳米汽车。

诺贝尔奖委员会认为这个最小化技术可能导致一场革命。

“2016诺贝尔化学奖得主们已经把分子系统从平衡的僵局状态脱离出来变成了充满能量的状态,其运动还是可控的。从发展的角度说, 分子发动机就好比是1830年代的电子发动机一样,科学家展示了各种旋转和轮轴,却没有意识到后来居然用到了电动火车,洗衣机,电风扇和食品加工机械。分子机器将来很有可能倍用于开发新材料,感应器和能量储存系统。”

所以林泽教授在一开始介绍的时候,继续拿着昨天物理学教授使用的瑞典肉桂卷做示范,因为它们都可能属于新材料类型的,只不过一个强调变相,一个强调的是分子本身可以象机器一样活动。

索瓦滋1944年出生于巴黎, 1971年获得博士学位,然后,一直担任斯特拉斯堡大学教授,和法国国家科研中心的主任。

斯铎达特1942年出生于英国的爱丁堡,1966年从爱丁堡大学获得博士学位。现在是美国西北大学的化学教授。

费令佳1951年出生于荷兰,1978年在格罗宁恩大学获得博士学位,然后在那里任教,是有机化学教授。

三位科学奖将均分800万克朗的奖金。诺贝尔奖将在12月10日颁发。明天将发布文学奖。医学和物理奖已经宣布。

Video: Top story: Sauvage, Stoddart and Feringa share 2016 Nobel Prize in Chemistry

By Xuefei Chen Axelsson

STOCKHOLM, Oct. 5(Greenpost)– The Nobel Prize in Chemistry 2016 has been awarded to Jean-Pierre Sauvage, Sir J Fraser Stoddart and Bernard Feringa for their design and production of molucular machines, announced Göran Hasson, Secretary General Of the Royal Swedish Academy of Sciences in Stockholm on Wednesday.

“The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry 2016 to

Jean-Pierre Sauvage,
University of Strasbourg, France

Sir J. Fraser Stoddart
Northwestern University, Evanston, IL, USA

and Bernard L. Feringa
University of Groningen, the Netherlands

“for the design and synthesis of molecular machines” “.

thumb_dsc_3337_1024Professor Sara Snogerup Linse,  Chairman of the Nobel Committee for Chemistry said  they developed the world’s smallest machines.

They have developed molecules with controllable movements, which can perform a task when energy is added.

 

According to the Nobel Committee, the development of computing demonstrates how the miniaturisation of technology can lead to a revolution. The 2016 Nobel Laureates in Chemistry have miniaturised machines and taken chemistry to a new dimension.

The first step towards a molecular machine was taken by Jean-Pierre Sauvage in 1983, when he succeeded in linking two ring-shaped molecules together to form a chain, called a catenane. Normally, molecules are joined by strong covalent bonds in which the atoms share electrons, but in the chain they were instead linked by a freer mechanical bond. For a machine to be able to perform a task it must consist of parts that can move relative to each other. The two interlocked rings fulfilled exactly this requirement.

The second step was taken by Fraser Stoddart in 1991, when he developed a rotaxane. He threaded a molecular ring onto a thin molecular axle and demonstrated that the ring was able to move along the axle. Among his developments based on rotaxanes are a molecular lift, a molecular muscle and a molecule-based computer chip.

Bernard Feringa was the first person to develop a molecular motor; in 1999 he got a molecular rotor blade to spin continually in the same direction. Using molecular motors, he has rotated a glass cylinder that is 10,000 times bigger than the motor and also designed a nanocar.

2016’s Nobel Laureates in Chemistry have taken molecular systems out of equilibrium’s stalemate and into energyfilled states in which their movements can be controlled. In terms of development, the molecular motor is at the same stage as the electric motor was in the 1830s, when scientists displayed various spinning cranks and wheels, unaware that they would lead to electric trains, washing machines, fans and food processors. Molecular machines will most likely be used in the development of things such as new materials, sensors and energy storage systems.

Jean-Pierre Sauvage, born 1944 in Paris, France. Ph.D. 1971 from the University of Strasbourg, France. Professor Emeritus at the University of Strasbourg and Director of Research Emeritus at the National Center for Scientific Research (CNRS), France.
