I want you to act as an academic journal editor. Please rephrase the paragraph from an academic angle based on the writting style of the Nature journal：Large-scale use of fossil fuels has caused serious pollution to the global environment. Therefore, there is an urgent need to develop and utilize new green and renewable energy sources, such as solar energy [1, 2], waterpower[3-6] and wind energy , to cope with the global energy crisis. Among them, solar energy has been widely used in the past decades because of its high efficiency, wide range of application, and no pollution emission. However, the working state of solar cells is greatly affected by the surrounding environment and weather, and the output drops abruptly or even almost does not output during rainy days. According to statistics, the annual global precipitation is about 5×105 m3. If all the kinetic energy generated by raindrops falling is captured and converted into electricity, it can generate about 0.5 TW of energy.
得益于制造工艺发展，当前的技术允许设计者在非常小的尺寸上集成数十亿晶体管来构造复杂的系统芯片。同步电路由于复杂的时钟网络在性能提升和功耗缩减方面都面临严重瓶颈。异步电路作为一种高性能低功耗的替代方法正在获得发展势头，一些工作也提出了专用的设计流程。但是这种针对纯异步电路的设计流程一方面给传统设计人员在电路设计层面带来很大的挑战。况且这种设计方法无法复用已有的同步电路，对于快速把统芯片推向市场极为不利。本文提出了创新的设计流程，首先，设计者把异步接口通路插入到同步描述的RTL将电路转换成GALS。其次，设计者对各个局部同步模块和各个异步接口通路设置时钟约束。最后，设计者基于传统EDA流程完成综合及物理设计并对所有约束进行检验。NoC在 GF22纳米 CMOS 工艺中实现，以验证所提出的设计流程。 转换后的 GALS 显示出优越的功率、性能和面积结果。整个设计流程花费的时间也明显减少。 上述这段话帮我翻译成英文。
润色下面英文：The controlled drug delivery systems, due to their precise control of drug release in spatiotemporal level triggered by specific stimulating factors and advantages such as higher utilization ratio of drug, less side-effects to normal tissues and so forth, provide a new strategy for the precise treatment of many serious diseases, especially tumors. The materials that constitute the controlled drug delivery systems are called “smart materials” and they can respond to the stimuli of some internal (pH, redox, enzymes, etc.) or external (temperature, electrical/magnetic, ultrasonic and optical, etc.) environments. Before and after the response to the specific stimulus, the composition or conformational of smart materials will be changed, damaging the original balance of the delivery systems and releasing the drug from the delivery systems. Amongst them, the photo-controlled drug delivery systems, which display drug release controlled by light, demonstrated extensive potential applications, and received wide attention from researchers. In recent years, photo-controlled drug delivery systems based on different photo-responsive groups have been designed and developed for precise photo-controlled release of drugs. Herein, in this review, we introduced four photo-responsive groups including photocleavage groups, photoisomerization groups, photo-induced rearrangement groups and photocrosslinking groups, and their different photo-responsive mechanisms. Firstly, the photocleavage groups represented by O-nitrobenzyl are able to absorb the energy of the photons, inducing the cleavage of some specific covalent bonds. Secondly, azobenzenes, as a kind of photoisomerization groups, are able to convert reversibly between the apolar trans form and the polar cis form upon different light irradiation. Thirdly, 2-diazo-1,2-naphthoquinone as the representative of the photo-induced rearrangement groups will absorb specific photon energy, carrying out Wolff rearrangement reaction. Finally, coumarin is a promising category photocrosslinking groups that can undergo [2＋2] cycloaddition reactions under light irradiation. The research progress of photo-controlled drug delivery systems based on different photo-responsive mechanisms were mainly reviewed. Additionally, the existing problems and the future research perspectives of photo-controlled drug delivery systems were proposed.
