Content: Marine CaCO₃ skeletons have tailored architectures created by nature, which give them structural support and other functions. For example, seashells have dense lamellar structures, while coral, cuttlebone and sea urchin spines have interconnected porous structures. In our experiments, seashells, coral and cuttlebone were hydrothermally converted to hydroxyapatite (HAP), and sea urchin spines were converted to Mg-substituted tricalcium phosphate [beta]-TCMP, while maintaining their original structures. Partially converted shell samples have mechanical strength, which is close to that of compact human bone. After implantation of converted shell and spine samples in rat femoral defects for 6 weeks, there was newly formed bone growth up to and around the implants. Some new bone was found to migrate through the pores of converted spine samples and grow inward. These results show good bioactivity and osteoconductivity of the implants, indicating the converted shell and spine samples can be used as bone defect fillers. Calcium phosphate powders were prepared through different synthesis methods. Micro- size HAP rods were synthesized by hydrothermal method through a nucleation-growth mechanism. On the other hand, HAP particles, which have good crystallinity, were prepared by wet precipitation with further hydrothermal treatment. [beta]-TCP or [beta]-TCMP powders were prepared by a two-step process: wet precipitation of apatitic tricalcium phosphate ('precursor') and calcination of the precursor at 800⁰C for 3 hours. [beta]-TCMP or [beta]-TCP powders were also prepared by solid-state reactions from CaHPO₄ and CaCO₃ with/without MgO. Biphasic calcium phosphate, which is mixture of HAP and [beta]-TCP, can be prepared though mechanical mixing of HAP and [beta]-TCP powders synthesized as above. Dense [beta]-TCP and [beta]- TCMP ceramics can be produced by pressing green bodies at 100MPa and further sintering above 1100⁰C for 2 hours. [beta]-TCMP ceramics ̃99.4% relative dense were prepared by this method. Dense [beta]-TCP ceramics have average strength up to 540MPa. Macroporous [beta]-TCMP ceramics were produced with sucrose as the porogen following a two- step pressing method. Porous [beta]-TCMP ceramics were also prepared by replication of polyurethane sponge. [beta]-TCMP ceramics with porous structures in the center surrounded by dense structures were created. The outside dense structures give the scaffold mechanical strength, while the central porous structures enable cells migration and vascular infiltration, and finally in-growth of new bone into the scaffold

Content: Wuqian (1922–2010) was one of the most important modern Buddhist masters in the modern history of Sino-Indian Buddhist relations. In his early years, he studied all the major schools of the Buddhist tradition, focusing on Yogācāra philosophy, probably due to Xuanzang’s influence and in alignment with contemporary Buddhist trends. Furthermore, he became one of the few masters from the Central Plains who received systematic training in Tibetan Buddhist tantric rituals. He went to India in the middle of the 20th century. He dedicated his life to the revival of Buddhist thought in India, especially promoting Chinese Buddhism in Calcutta by establishing Buddhist institutions, managing Buddhist sites, organizing Buddhist activities, and building the Xuanzang Temple. In his later years, he devoted himself to facilitating mutual Buddhist exchanges and monastic visits between Buddhist organizations in mainland China, Taiwan, and India. In 1998, he presented two Buddhist relics to the Daci’en Temple in Xi’an. At the beginning of the 21st century, he established the Institute of Buddhist Studies at Xuanzang Temple in Calcutta. He organized the translation of many important Buddhist treatises, again reflecting his intention of following the spirit of Xuanzang to contribute to Chinese Buddhism. His transnational journey manifested that there was an active Asian Buddhist network during the Cold War era, despite various difficulties.

Content: Immigrants from China started settling in Calcutta, the British capital of colonial India, from the late eighteenth century. Initially, the immigrant community comprised of male workers, many of whom sojourned between China and India. Only in the early twentieth century was there a large influx of women and children from China. To address the educational needs of the children - both immigrant and locally-born - several Chinese-medium primary and middle schools were established in Calcutta by the community in the 1920s and 1930s. Using many hitherto unexplored textual sources and interviews in India, China, and Canada, this detailed and unprecedented study examines the history and significance of these Chinese-medium schools. It focuses on the role they played in preserving Chinese cultural identity not only through the use of educational curricula and textbooks imported from China, but also with the emphasis on the need to return to the ancestral homeland for higher education. This study also breaks new ground by examining the impact of political and other factionalism within the community as well as the India-China conflict of 1962 that resulted in the closure of most of the Chinese-medium schools in Calcutta by the 1980s.
