    Do Geographically Isolated Grasslands Follow the Principle of Island Biogeography in a Landscape Scale? Taking Poyang Lake Grassland as an Example

    Shiqi Luo1,3, Wenbo Chen2,3,*, Lei He4, Qiongbing Xiong1,3

    Phyton-International Journal of Experimental Botany, Vol.92, No.2, pp. 455-470, 2023, DOI:10.32604/phyton.2022.022466

    Abstract As one of the basic theories of biodiversity conservation, island biogeography has been widely accepted in the past decades. Originally, island biogeography was put forward and applied in oceanic environments. But later on, it was found out that the application was not only limited to oceanic islands, but also in terrestrial environments with relatively isolated conditions. In terms of biodiversity level, island biogeography generally focuses on a small scale, such as species diversity and genetic diversity. The studies of biodiversity on a large-scale based on island biogeography, such as ecosystem and landscape scales, were seldomly conducted. Taking Poyang Lake, the… More >

    Hyoe Hatakeyama1,*, Tatsuko Hatakeyama2

    Journal of Renewable Materials, Vol.1, No.2, pp. 113-123, 2013, DOI:10.7569/JRM.2012.634111

    Abstract Lignin and saccharides are two major components of plants. Huge amounts of plant residues are obtained as by-products of large-scale industries, such as pulp and paper, bio-fuel and the food industry. In this paper, preparation of polyurethane (PU) foam directly from various kinds of industrial lignin and molasses, which have scarcely been utilized, is summarized based on our results obtained by recent investigation. A onestep reaction using hydroxyl groups of plant materials as an active site makes it possible to produce a wide variety of PU, such as foams, sheets, gels and composite matrix. In this paper, PU foams receive… More >

    Curing Kinetics of Tannin and Lignin Biobased Adhesives Determined by DSC and ABES

    Jaša Saražin1, Ida Poljanšek1, Antonio Pizzi2, Milan Šernek1,*

    Journal of Renewable Materials, Vol.10, No.8, pp. 2117-2131, 2022, DOI:10.32604/jrm.2022.019602

    Abstract The curing process of two biobased adhesives: pine tanninhexamine (TH) and organosolv lignin non-isocyanate polyurethane (NIPU), suitable for interior nonstructural use, were compared with commercial urea-formaldehyde (UF) adhesive. Changes in chemical structure before and after the curing process were observed with Fouriertransform infrared spectroscopy (FTIR). The process of adhesive curing was monitored with differential scanning calorimetry (DSC) and the automated bonding evaluation system (ABES). Both DSC and ABES measurements confirmed UF as the fastest and NIPU as the slowest curing adhesive observed. Taking into account the ABES results, the optimal pressing parameters for the TH adhesive would be 4 min… More >

    Characterization of three-dimensional multipotent adipose-derived stem cell spheroids

    HONGYANG LI1,2, CHAN WANG4, SHIWEI LIU1, YONGLONG GUO1,3,4,*, JIANSU CHEN1,3,4,*

    BIOCELL, Vol.46, No.7, pp. 1705-1716, 2022, DOI:10.32604/biocell.2022.018442

    Abstract Human adipose stem cells (hADSCs) are reliable sources for cell therapy. However, the clinical applications are limited by the decrease in activity during in vitro culture. We used a knockout serum replacement (KSR) medium, Eppendorf (EP) tube culture, and a simulated microgravity (SMG) culture system to establish hADSC spheroids. We found that hADSCs aggregated and formed spheroids in the KSR culture medium. The EP tube culture method revealed many biological cell characteristics, such as good cell viabilities, rough surfaces, polar growth, fusion phenomenon, and injectability. The findings show its advantages for hADSCs spherical cultures. When cultured in SMG, hADSC spheroids… More >

    FDMP-Fluid Dynamics & Materials Processing, Vol.18, No.1, pp. 71-80, 2022, DOI:10.32604/fdmp.2022.017922

    Abstract In this study a Cu43Zr48Al9 bulk metallic glass prepared by the copper mold casting method is considered. In recent years, Cu-Zr-Al systems like this have enjoyed widespread attention due to their high strength, high hardness, high corrosion resistance and low cost. Here samples of this substance are studied using DSC (Differential scanning calorimetry) to determine the effect of different test conditions (heating rate, sample mass, sample specific surface area and sample crystal phase) on the characteristic thermodynamic temperature of the bulk metallic glass. Experimental results show that almost all of the five characteristic thermodynamic temperatures (Tg, Tx, Tp, Tm, Tl)… More >

    Differential metabolome landscape of Kadsura coccinea fruit tissues and potential valorization of the peel and seed tissues

    JIANFEI GAO1, KANGNING XIONG2,*, WEIJIE LI1, WEI ZHOU3

    BIOCELL, Vol.46, No.1, pp. 285-296, 2022, DOI:10.32604/biocell.2021.016253

    Abstract Kadsura coccinea (Lem.) is a woody wine plant with a peculiar fruit enriched in important health-promoting compounds. The non-editable part of the fruit, i.e., the seed and peel, represents more than 60% of the fruit and is considered a biowaste. This significantly restricts the development of the K. coccinea fruit industry. Clarifying the metabolic components of the different fruit parts can help to improve the utilization rate and valorization of K. coccinea. Herein, we evaluated K. coccinea fruit peel, pulp, and seed using widely-targeted metabolomics and quantified a set of 736 bioactive compounds from 11 major metabolite classes. The most… More >
