Progress of Solidification Researches and the Applications in Materials Processing

The research achievements of solidification theories and technologies in the last decades are reviewed with the stresses on some new development in the recent years. Some new interesting areas emerged in the last years are also pointed out.

South China University of fechnology Advanced Metallic Materials Research and Processing Technology Center

A dvanced Metallic Materials Research and Processing Technology Center was found in December 1998. As a unit under The College of Mechanical Engineering, the Center is an expansion of the former Cast and Composite Materials Research Group, which was found in the early eighties of last century. The Center is focusing in the basic and applied research, and development of advanced metallic materials and their processing technology. It also functions as an organization

Tsinghua University Tsinghua-TOYO Research and Development Center of Magnesium and Aluminum Alloys Processing Technology

Tsinghua-TOYO Research and Development Center of Magnesium and Aluminum Alloys Processing Technology was officially established between Tsinghua University and TOYO Machinery & Metal Co. on Feb. 26, 2002, which is a non-independent legal research organization located in Department of Mechanical Engineering of Tsinghua University. The center was equipped with one set of 650t automatic magnesium and aluminum alloys diecasting machine and necessary accessories including the melting furnaces for magnesium alloys and aluminum alloys, an accurate magnesium pump to transfer the magnesium alloys to the shot sleeve of the die casting machine, a die temperature controller, and data logging systems for cavity pressure and die temperature distributions, etc. The center is aimed to the research and development of magnesium and aluminum die casting process and their related technologies, and the main research contents include:

The Association between Researchers’Conceptions of Research and Their Strategic Research Agendas

Purpose:In studies of the research process,the association between how researchers conceptualize research and their strategic research agendas has been largely overlooked.This study aims to address this gap.Design/methodology/approach:This study analyzes this relationship using a dataset of more than 8,500 researchers across all scientific fields and the globe.It studies the associations between the dimensions of two inventories:the Conceptions of Research Inventory(CoRI)and the Multi-Dimensional Research Agenda Inventory—Revised(MDRAI-R).Findings:The findings show a relatively strong association between researchers’conceptions of research and their research agendas.While all conceptions of research are positively related to scientific ambition,the findings are mixed regarding how the dimensions of the two inventories relate to one another,which is significant for those seeking to understand the knowledge production process better.Research limitations:The study relies on self-reported data,which always carries a risk of response bias.Practical implications:The findings provide a greater understanding of the inner workings of knowledge processes and indicate that the two inventories,whether used individually or in combination,may provide complementary analytical perspectives to research performance indicators.They may thus offer important insights for managers of research environments regarding how to assess the research culture,beliefs,and conceptualizations of individual researchers and research teams when designing strategies to promote specific institutional research focuses and strategies.Originality/value:To the best of the authors’knowledge,this is the first study to associate research agendas and conceptions of research.It is based on a large sample of researchers working worldwide and in all fields of knowledge,which ensures that the findings have a reasonable degree of generalizability to the global population of researchers.

A Critique of Eye-Tracking Approach in Translation Process Research

With the rapid growth of eye-tracking studies in translation process research, concomitant methodologicalproblems have become increasingly prominent. This paper starts with the discussion of the controversial “eye-mindassumption”, and then focuses on various threats to experimental validity in research design and problems witheye-tracking data filtering and analysis. It is hoped that this discussion would be beneficial to those who are now orwill be engaged in eye-tracking based translation studies.

Current Status and Prospect of Process Research in CISRI

The Central Iron and Steel Research Institute(CISRI),directly under the Ministry of Metallurgical Industry(MMI),is a comprehensive research institute mainly engaged in the research and development of new metallic materials and new iron and steel process.With the rapid development of China’s iron and steel industry,CISRI has also made a great progress since it was established more than 40 years ago.In 1994,the steel output of

GLOBAL SUBSTORM PROCESSES IN GEOSPACE AND FRONTIERS IN SUBSTORM RESEARCH

This paper discusses the problems we confront in the study of magnetospheric substorms. This includes the global processes of magnetospheric substorms, the origin of the southern-northern component of interplanetary magnetic field, quantitative effects of the interplanetary conditions, driving processes of the solar wind, location of the triggering of the expansion phase, and relationship between magnetospheric storms and substorms. Moreover, the research directions in the future have also been discussed.

Development and Performance Evaluation of Catalyst for Productive Ethylene Cracking Feedstock in Selective Hydrocracking of Straight Run Diesel Oil

The upgrading of diesel oil to produce ethylene rich cracking feedstock is an important and promising technical route to reduce the ratio of diesel to gasoline. In the present work, a hydrocracking catalyst suitable for selective hydrocracking of straight run diesel oil to produce high-quality ethylene cracking feedstock at low cost was developed, by optimizing the composition of catalyst support materials, using amorphous silicon aluminum and aluminum oxide with high mesopore content as the main support, and modified Y zeolite with excellent aromatic ring opening selectivity as the acidic component. The catalyst has in-depth characterized by X-ray diffraction, transmission electron microscopy, scanning electron microscopy, N2-low temperature adsorption-desorption, NH3-temperature-programmed desorption, and IR techniques. And its catalytic cracking straight run diesel oil performance was evaluated. The results show that the prepared catalyst has high polycyclic aromatic hydrocarbon ring opening cracking selectivity. However, alkanes retained in diesel distillates can achieve the goal of producing more ethylene cracking feedstocks with low BMCI value under low and moderate pressure conditions. This work may shed significant technical insight for oil refining transformation.
