The purpose of this paper is to review the evolution of policies and practices of open innovation (OI) in China under globalization.

This is a review paper. It combines historical archives and case study approaches, covering policies and practices at both the macro‐ and micro‐levels.

It is found that Chinese firms have in practice employed a variety of OI models since the reforms of science and technology systems in the mid‐1980s. Policies introduced by the Chinese Government with respect to inbound and outbound OI, as well as policies encouraging OI networks, have encouraged Chinese firms to adopt various OI modes and practices. Some critical institutional challenges still need urgent attention and effective efforts to reinforce them.

This paper aims to fill the gap in the literature by providing the first systematic review of the evolution of the policies and practices of OI in China, and exploring the implications for latecomer firms in building indigenous innovation capability. As far as the authors are aware, this is one of the first systematic review studies on OI policies and practices with a focus on emerging economies.

Various forms of regional cooperation in East Asia have greatly increased in the past two decades. Scientific collaboration is beneficial for both scientifically lagging countries (SLCs) and scientifically advanced countries (SACs) with respect to their S&T capacity and thus economic prosperity. This paper aims to provide a comprehensive description of intra‐regional scientific collaboration in East Asia from 1985 to 2008 with the 10+3 (ASEAN ten plus China, Japan and South Korea) framework.

The paper uses co‐authored articles embodied by Science Citation Index Expanded (SCI‐Expanded) to indicate cross‐border scientific collaboration.

Data show that heterogeneity in the publication output across East Asian countries is decreasing. Intra‐ASEAN, intra‐ Northeast Asia, as well as ASEAN and Northeast Asia scientific collaboration greatly improved since 1997.

This paper discusses factors influencing international scientific collaboration and focuses on explaining the impact of regional integration. Finally, it offers further suggestions on East Asian integration from the perspective of scientific collaboration.

This paper aims to study the micro-structure evolution of friction layers to optimize the friction and wear behaviors of TiAl-based material. It further enlarges the scope of using TiAl alloys and increase in the service life of TiAl alloy-made mechanical components, especially under some extreme conditions.

To study the structure evolution of friction layers, the HT-1000 tribometer is used to study the friction and wear properties of as-prepared samples. With the assistance of field emission scanning electron microscopy and an electron probe micro-analyzer, the stratified structures in cross-sections and a surface morphology of the wear scars are well characterized. A ST400 surface profiler helps in better understanding of the three-dimensional texture profiles of wear scars. X-ray diffractometer (XRD) is also used to analyze phases in the as-prepared samples.

An analysis method on the micro-structure evolution can provide better views to understand the influence of friction layers on the tribological behavior, at different wear stages. It finds that the micro-structure evolution of friction layers has an immediate effect on the friction coefficients and wear rates of TiAl-based material. It also proves to be a useful tool for evaluating the behaviors in friction and wear of TiAl-based material.

The findings of this paper provide better assistance to explore the effect of friction layers on the friction and wear behaviors of TiAl-based materials. The results help in deep understanding of the micro-structure evolution of friction layers. It also increases the service life of TiAl-based mechanical components.

This paper aims to study the corrosion inhibition behavior of imidazopyridine and its three derivatives on brass.

The authors performed weight loss experiments, electrochemical experiments including the polarization curve and electrochemical impedance spectrum, corrosion morphology observation using scanning electron microscope (SEM) and atomic force microscope (AFM) and surface composition analysis via X-ray photoelectron spectroscopy (XPS) to analyze the corrosion inhibition behavior of imidazopyridine and its three derivatives on brass by using quantum chemical calculation (Gaussian 09), molecular dynamics simulation (M-S) and Langmuir adsorption isotherm.

According to the results, imidazole-pyridine and its derivatives were found to be modest or moderately mixed corrosion inhibitors; moreover, they were spontaneously adsorbed on the metal surface in a single-layer, mixed adsorption mode.

The corrosion inhibition properties of pyrazolo-[1,2-a]pyridine and its derivatives on brass in sulfuric acid solution were analyzed through weight loss and electrochemical experiments. Moreover, SEM and AFM were simultaneously used to observe the corrosion appearance. Furthermore, XPS was used to analyze the surface. Then, Gaussian 09 and M-S were combined along with the Langmuir adsorption isotherm to investigate the corrosion inhibition mechanism of imidazole-[1,2-a]pyridine and its derivatives.
