Other than its biology significance, DNA also plays an important role in materials science and nanotechnology. It has been well established that DNA could serve as an ideal material for “bottom-up” construction of nano-scale patterns. In this review, recent development of DNA based nanomachines which relies on the responsible secondary structure changes has been summarized and cataloged according to different driven mechanisms. The advantages and shortcomings of each driven mechanism have also been compared. In addition, this review has summarized much efforts in demonstrating working ability of DNA nanomachine, which is critical for the development. Recent progress in using DNA nanomachine to fabricate nanodevices and smart surfaces has also been addressed to illustrate its potential application in materials science and diagnostics in the future.
Yu Angyang. Some developments of Geometric Phase Effects in Chemical Reactions[J]. Progress in Chemistry, 2008, 20(0203): 208-211.
Despite the central position of Born-Oppenheimer approximation in chemical theory, its breakdowns, electronically nonadiabatic processes are ubiquitous. On the ground state potential energy surface, a conical intersection produces the geometric phase effect. A conical intersection could influence the nuclear dynamics through the geometric phase effect. The origin of the geometric phase effect and some theoretical approaches including the geometric phase effect are reviewed. Some recent results concerned with the geometric phase effect in the reaction dynamics are demonstrated and there are explanation for these intriguing results. There are also some predictions for the future of the geometric phase effects in reaction dynamics. It is pointed that the geometric phase effect will play the most important role in nonadiabatic chemistry.

The study on synthesis of the chiral Schiffbase transition metal complexes and their catalytic performance has attracted more attentions due to their applocations in the asymmetric epoxidation of olefins. This article summarises some recent results on the chiral Schiffbase transition metal complexes and their catalytic applications in the asymmetric epoxidation of olefins, including the synthesis and their activities of several novel Schiffbase transition metal complexes.

Polylactic acid (or Polylactide) (PLA) widely used in many field because of its biodegradable and biocompatible properties, have gained enormous attention recently. However, onefold structure and properties limits the applications of PLA homopolymer. The most common strategy to overcome this limit is to prepare the copolymers. A wide range of biodegradable copolymer are described in this review with a special emphasis on polylactide because of more eco-friendliness from its origin as contrast to the fully petroleum-based biodegradable polymers and control of carbon dioxide balance after their compositing. Lactic acid (or lactide) copolymerized with hydroxyl acid, amino acid or polymers such as poly(ethylene glycol), starch, etc. , can obviously improve the strength, toughness, hydrophilic and controlled-degradable properties of PLA, and in the same time can obtain the linear, comb-like, star-like or cross-linked copolymers. These materials are attracting considerable interest in materials science research. This review aims at highlighting on recent developments in preparation of biodegradable linear, comb-like, star-like or cross-linked PLA copolymers and the catalysts (system) used in copolymerization.

. Preparation and Application of Smart Coatings[J]. Progress in Chemistry, 2008, 20(0203): 351-361.Smart coatings were developed from novel and special function coatings in recent years. Here, the preparation and application of different smart coatings are summarized in details. The polymer film, pigment and manufactural technological should be considered in preparation of smart coatings. Among them, the key is the disign and the synthesis of stimuli-responsive polymeric films which exhibit “switchable” and desirable properties depending upon external environments because it associates with formation and surface properties of films. The controlled / living polymerization, surface grafts and lay-by-lay assemblies techniques have been applied in preparation of intelligent polymer for coatings. In addition, nanotechnology is one of the important method for preparation of smart coatings. At present, the state of their development is still on initial stage of nanotechnology-based smart coating. The main kinds of smart coatings are self-cleaning coatings, anti-bacterial coatings, anti-corrosive coatings, camouflage coatings, luminescent coatings and magnetic coatings, which are sensitive to the change of light, electricity, magnetic force, temperature, humidity and pressure. However, the high level smart coatings based on the intelligent polymers are still being studied.

. Anticancer Activity of Indolocarbazoles[J]. Progress in Chemistry, 2008, 20(0203): 368-374.Indolocarbazole is a certain kind of alkaloid extracted by microbe fermentation. These compound, including their derivatives, such as staurosporine, ED-11, NB-506, rebeccamycin, azaindolocarbazole, indolocarbazole glycosides and bisindolylmaleimides, can act on many targets to exert anticancer function. It is now known that indolocarbazoles are effective topoisomerase poisons,and that they also inhibit protein kinases by competitively combining to special amino acid groups of the ATP pocket, which later causes the cell arrest in the G1 phase. During the recent years, researchers endeavored to look for better forms of these chemicals to act as selective inhibitors with improved anticancer activity. This review will mainly discuss the research progress, clinical applications, anticancer activity mechanism, and their structure-activity relationship (SAR) of indolocarbazole derivatives.

Zhang Xiongfu. Direct Hydroxylation of Benzene to Phenol[J]. Progress in Chemistry, 2008, 20(0203): 386-395.
The one-step process for direct hydroxylation of benzene to phenol is one of very hot topics. So far, many research efforts made for direct hydroxylation of benzene to phenol are mainly focused on three preparation routes by adopting N2O、H2O2 and O2 as oxidants respectively. In this paper, the progress in these routes of direct hydroxylation of benzene to phenol is reviewed in detail. The characteristics and prospects of their industrial applications are also discussed. The route for direct oxidation of benzene to phenol with N2O as a oxidant is technologically practicable, however, the process economics is strongly dependent on obtaining a cheap supply of N2O as a by-product in the production of adipc acid. On-purpose production of N2O as a feedstock for the process is economically unfeasible now. Thus the application of the technology is severely limited to just a few sites where N2O from adipic acid manufacture can be readily accommodated in the downsteam direct oxidation process. The route for phenol preparation with H2O2 as oxidant is an environmentally friendly process, however, it is technologically unfeasible now due to lower efficient utility for H2O2 and higher phenol production cost. And also expensive H2O2 shows negative effect on the economics of its industrial application. In comparison, the process for direct hydroxylation of benzene to phenol with O2- H2 is an environmentally clean and sustainable route. It is of potential prospect in both academic research and technological development aspects. The route of direct oxidation of benzene to phenol with O2- H2 system by using inorganic membrane reactor is more attractiving because of its higher conversion, selectivity and safer operation.
