    In vitro polymerization of the dopamine-borate melanin precursor: A proof-of-concept regarding boron neutron-capture therapy for melanoma


    BIOCELL, Vol.47, No.4, pp. 919-928, 2023, DOI:10.32604/biocell.2023.026631


    The 10boron neutron-capture therapy (BNCT) is an emerging antitumoral method that shows increasing biomedical interest. BNCT is based on the selective accumulation of the 10boron isotope within the tumor, which is then irradiated with low-energy thermal neutrons, generating nuclear fission that produces 7lithium, 4helium, and γ rays. Simple catechol-borate esters have been rather overlooked as precursors of melanin biosynthesis, and therefore, a proof-of-concept approach for using dopamine-borate (DABO) as a suitable boron-containing candidate for potential BNCT is presented here. DABO can spontaneously oxidize and autopolymerize in vitro, giving a soluble, eumelanin-like brown-black poly-DABO product. Melanotic melanoma cell cultures treated

    Insight into Hydrolytic Stability and Tribological Properties of B-N Coordination Tung Oil-Based Lubricant Additive in Water

    Na Yao1,2, Haiyang Ding1,2,*, Mei Li2, Pengcheng Wang3, Shouhai Li1,2, Lina Xu2, Xiaohua Yang2

    Journal of Renewable Materials, Vol.11, No.3, pp. 1367-1381, 2023, DOI:10.32604/jrm.2022.023411

    Abstract A tung oil-based boron-nitrogen coordination polymer (TWE-BN) was specially designed and synthesized as a highly efficient water-based lubricant additive, which has been beneficial to both energy conservation and conducive to environmental protection. Its hydrolysis stability and tribological properties in water were investigated. To better research the lubricating properties, and thus to understand the interaction between the surface and the lubricating additives. Herein, both experimental and theoretical computations based on density functional theory (DFT) were performed. The addition of TWE-BN reduces the water friction coefficient and wear scar diameter, and the maximum non-seizure load increased from More > Graphic Abstract

    Borate-Modified, Flame-Retardant Paper Packaging Materials for Archive Conservation

    Juanli Wang1, Ming Cao2, Jiaxin Li1, Kaiyuan Li1, Xiaolian Chao1, Bingjie Mai1, Yuhu Li1,*, Jing Cao1,*

    Journal of Renewable Materials, Vol.10, No.4, pp. 1125-1136, 2022, DOI:10.32604/jrm.2022.018147

    Abstract Paper packaging materials like cardboards are widely used to protect archives which are a major kind of cultural relics. Unfortunately, paper is a combustible material, and thus exploring environment-friendly flame retardant for paper-based archive packaging material plays an important role. Herein, boric acid, borax and disodium octaborate are used to modify the craft paper-based packaging materials for archive conservation to improve fire safety. The modified craft paper exhibits much higher flame retardancy than the pristine one dose based on vertical burning tests, without much influence on mechanical properties such as tensile strength and elongation at More > Graphic Abstract
