2021.不平凡的一年,亲人离世,换了座城市生活,谈了场荒唐的恋爱,做了件国内没有的设备。

2022.只会有更多的挑战。要珍惜身边的人,对自己负责呀

希望未来有机会可以去想去的国家,过想过的生活。

In the fifth week, I have made a partial surveyon the topic that tunnelling current noise and active sites, as well as in-situor operando conditions. The related articles published in web of science arealmost made by Aliaksandr, even the different keywords have been searched.Their works I focus on are all related to how to identify the electrocatalyticsurface sites by EC-STM in reaction conditions. After learning about the paperpublished in Nature on the current noise and active sites, I have read their articletitled “In situ Quantification of the Local Electrocatalytic Activity viaEC-STM”. The author elaborated a new method for the in-situ quantification ofthe electrocatalytic activity. And they found the linear correlation betweenthe noise and activity levels, which can be determined in terrace and stepssites, respectively. Last, the author introduced the enhancement factor TOFs/TOF,which serves as a descriptor for the activity of the sample.

In addition, I have learnt about the partial applicationof Kelvin probe force microscopy (KPFM), which used for imaging of anisotropiccharge and characterizing charge distribution in complex molecular system andon surfaces. The related research published in Science opened a new way thatdirect experimental visualization to characterize biological and chemicalsystems. A brief understanding on the origin of the electrostatic interactionof KPFM, offered by supporting information, demonstrated that how to obtain thecontact potential difference VCPD. The detail, is that to make analignment of the Fermi level of the tip and sample before they were connectedby an electric circuit. After that, the difference between work function ofsample and tip caused charge transfer between sample and tip. Meanwhile, thechange of field forming in interface will be compensated by an external bias,and therefore allows one to determine the contact potential difference VCPD.The contact potential difference VCPD will be reflected by the vertex of ∆f-V parabola.

science作为两种nature之间的桥梁

       首先,我认为科学是一种十分罕见的人类文化现象。它没有诞生在拥有灿烂文化的中国,更没有诞生在古印度,古埃及,而是诞生在了古希腊。因此要谈论科学的本质特征,应该从它诞生的先决条件说起,希腊人特有的“生人文化”造就了自由的这一人性理想,要实现自由,他们给出的答案是科学。因此科学就沾染上了本真、纯粹、本质、自然、真实、正确、唯一、确定性等等一系列标签,从而了解自然,改造自然,实现人对自然的可操作,从而通往自由。

       首先,我认为科学是一种十分罕见的人类文化现象。它没有诞生在拥有灿烂文化的中国,更没有诞生在古印度,古埃及,而是诞生在了古希腊。因此要谈论科学的本质特征,应该从它诞生的先决条件说起,希腊人特有的“生人文化”造就了自由的这一人性理想,要实现自由,他们给出的答案是科学。因此科学就沾染上了本真、纯粹、本质、自然、真实、正确、唯一、确定性等等一系列标签,从而了解自然,改造自然,实现人对自然的可操作,从而通往自由。

       说到自然,我认为这是科学的最大特征。虽然纯粹的科学也包括哲学,曲艺,数学,绘画等等,但是真正能提供生产力的,能让大多数人沉迷的,也就是现代科学,研究自然规律的科学。

       自然,这个名词在今天的大多人看来,是指我们是存在的客观环境,花草,树木,天地,这是个由日本译来的西方词汇,nature。本意为本性,事物的本质,可是为什么要翻译为自然呢?在这里不讨论这个问题。

       我们中国的“自然”,不是一个名词,不能问“自然”是什么。自是自己,然是如此,自然的反义词是使然。中国古代,我们当然能认识到山川草木,虫鱼鸟兽,可是我们的人性理想要求我们“礼”是实现人性理想的手段,因此天地,万事万物都要和人挂钩,包括研究天文,都要赋予其灵魂、思想、意志。也因此,我们开发不出属于周围客观环境的领域。我们也就自然没有nature这个词汇。

       但是希腊人不一样,他们认识到了nature,并且将其分离出来,所发展的自然科学甚至哲学虽然起初不是奔着功利性去的,但是近代以来确实取得了惊人的成效,并且全世界也纷纷效仿,无疑是改变了人类发展进程。

       很凑巧,nature在西方有两个意思,一个是事物的本质、本性,另一是客观环境。而这两个意思之间一定存在着关联,而连接的桥梁就是科学,是science,理解客观环境的本质、本性,就是science。

In this week, I have learnt the articletitled “Direct instrumental identification of catalytically active surfacesites” published in Nature. The main point of author is that directly identifyand monitor active sites in operando conditions by the tunnelling current noiseof EC-STM or STM, which making it then possible to evaluate the relativecontribution to overall catalyst activity of different defects and activesites. In addition, the tunnelling current noise reflected the active sites isa function as time compared with those over non-active sites, and therefore thecurrent noise can record the changes of active sites in reaction conditions.It’s worth noting that the Faradaic current of hydrogen oxidation between tipand sample is influenced to the tunnelling current noise useful for us, whereasthe vibration is slightly. The details have been discussed in experimentalmethods.

That's not all.
