Technology and commercial application of UFR to VRDS unit expansion at Qilu Petrochemical Company, for which engineering work was done by SINOPEC Engineering Incorporation （the former Beijing Design Institute）, were introduced. Successful experience for the first commercial application of up-flow reactor technology and debottlenecking of the unit were summarized. The findings revealed a new route for inferior residue hydrotreating and revamping the existing units of the like.

In many applications, the system dynamics allows the decomposition into lower dimensional subsystems with interconnections among them. This decomposition is motivated by the ease and flexibility of the controller design for each subsystem. In this paper, a decentralized model reference adaptive iterative learning control scheme is developed for interconnected systems with model uncertainties. The interconnections in the dynamic equations of each subsystem are considered with unknown boundaries. The proposed controller of each subsystem depends only on local state variables without any information exchange with other subsystems. The adaptive parameters are updated along iteration axis to com- pensate the interconnections among subsystems. It is shown that by using the proposed decentralized controller, the states of the subsystems can track the desired reference model states iteratively. Simulation results demonstrate that, utilizing the proposed adaptive controller, the tracking error for each subsystem converges along the iteration axis.

The one-pot sequential reaction of arylamines, methyl propiolate and 2-aryl-3-nitrochromenes without any catalyst in refluxing ethanol afforded the polysubstituted 3-（3-nitro-2-phenylchroman-4-yl）-3-arylaminoacrylates in good yields and with high diastereoselectivity. Reaction mechanism was believed involving the initial formation of β-enamino ester and sequential Michael addition.

Severe erosion by hard particles is a crucial problem to engine blades when aircraft take off and land in harsh environments, especially for the developed lightweight titanium alloy components. Here, we deposited the Ti/TiAlN multilayer coatings with various cycles on Ti–6 Al–4 V substrates by a home-made hybrid multisource cathodic arc system. The effects of the silica sand and glass beads on erosion behavior of the coatings were focused. Results showed that the Ti/TiAlN multilayer coatings eroded by the silica sand exhibited the predominant "layer by layer" failure mechanism. In particular, increasing the number of cycles led to the dramatic increase in erosion rate for Ti/TiAlN multilayer coatings, due to the deterioration of their mechanical properties. Different from the silica sand case, however, the erosion rate of the coatings treated by glass beads indicated faint dependence upon the number of cycles, where the coating failure was dominated by the "piece by piece" failure mechanism. Noted that the Ti layers along with the formed interfaces enhanced the erosion resistance of the coatings, although the failure mechanisms were differently eroded by silica sand and glass beads. Meanwhile, the Ti layers and interfaces hindered the propagation of radial cracks and restrained the lateral cracks within one single TiAlN layer.

Summary of main observation and conclusion Four acyclic maleimide-based enediyne compounds with different hydrophilicity were synthesized through Sonogashira reaction to reveal a self-delivery antitumor drug platform. As proved by ESR analysis, the enediyne compounds undergo Bergman- like cyclizati on and generate diradical in termediates at physiological temperature, which are able to induce DNA-cleavage through the abstraction of H atoms from the sugar-phosphate backbones. When the critical aggregation concentration is reached in water, the amphiphilic enediyne compounds self-assemble into nanoparticles and possess the self-delivery ability to be facilely admitted by tumor cells, resulting in greatly improved cytotoxicity (IC50 down to 10 μmol·L^-1) and much higher tumor cell apoptosis rate (up to 86.6%) in comparison with either the hydrophilic or the lipophilic enediyne compound. The enhanced endocytosis of the amphiphilic en ediyne compo unds was further confirmed through con focal laser scan ning microscopy analysis. The unveiled relationship between the hydrophilicity of enediyne drugs and their therapeutic efficacy will provide a guideline for the design of new self-delivery drugs employed in medicinal applications.
