  1. Ethnobotanical study of medicinal plants used by the Jah Hut peoples in Malaysia
    Lin KW
    Indian J Med Sci, 2005 Apr;59(4):156-61.
    PMID: 15876780
    CONTEXT: An ethnobotanical study was carried out among the Jah Hut people who live in the central part of peninsular Malaysia.

    MATERIALS AND METHODS: The information on the medicinal plants was obtained from interview with a traditional medicinal man. The traditional uses and remedies were documented. The literature searches were carried out for the evaluation on the current status of investigations on these plants.

    RESULTS: In this study, we present 16 species of plants, which are commonly used among the Jah Hut people to cure some common diseases.

    DISCUSSION: This study is important to preserve the knowledge of medicinal plants used by Jah Hut people. The surveys of phytopharmacological literatures of these plants have great pharmacological and ethnobotanical significance.

    The high-speed data transmission capability of photomemory is expected to overcome the von Neumann bottleneck, making it a key target for next-generation technological development. With the growing emphasis on environmental sustainability, bio-based materials have attracted increasing attention in recent years due to their rich functional groups, which offer great versatility and application potential. This study employs Ruddlesden-Popper (RP)-phase quasi-2D perovskite (Q-2D PVSK) and bio-based material as the electret layer in non-volatile photomemory, achieving high performance through a simple fabrication process. The results show that the incorporation of bio-based materials leads to devices with high carrier mobility (∼10-2 cm2/V·s), a high Ion/Ioff current ratio (3.19 × 105), and a broad memory window (∼35 V). Moreover, even after multiple cycles, the device maintains a strong photocurrent (∼10-5 A), and long-term retention measurements (∼20,000 s) reveal no significant current degradation. These results validate that the synergistic interaction between bio-based material and Q-2D PVSK significantly enhances both the memory characteristics and the operational stability of the device, demonstrating their strong potential for next-generation nonvolatile photomemory applications.
