    Minglei Hu1, Wei Zhang1, Bin Hu1, Haicun Yang2, Fuqiang Chu2, Zheng Cao2,*

    Journal of Polymer Materials, Vol.42, No.4, pp. 1125-1141, 2025, DOI:10.32604/jpm.2025.073300 - 26 December 2025

    Abstract Polypropylene (PP) has low inherent susceptibility to common industrial lasers, which poses a significant challenge for laser-based marking. To improve the laser sensitivity of PP, molybdenum disulfide grafted with polystyrene (MoS2-g-PS) was synthesized via in-situ free radical polymerization and used as a laser-sensitive filler for PP composites prepared by melt blending. The composites were then marked with a 1064 nm semiconductor laser, producing clear and legible patterns. The marked surfaces were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), colorimetry, Raman spectroscopy, and thermogravimetric analysis (TGA). The results demonstrate that the PP/MoS2-g-PS composites exhibit significantly More >

    Noverra Mardhatillah Nizardo1,*, Alifah Nurul Saffanah1, Annisa Fitri Salsabila1, Amanda Aurellia Putri1, Aniek Sri Handayani2, Azizah Intan Pangesty3, Mochamad Chalid3

    Journal of Renewable Materials, Vol.13, No.6, pp. 1209-1227, 2025, DOI:10.32604/jrm.2025.02024-0068 - 23 June 2025

    Abstract Food packaging is becoming popular as the consumption of ready-to-eat food products rises. Easy-to-use, non-biodegradable plastic packaging is commonly used in food packaging, contributing to the deteriorating environmental situation. This issue increases the concern for the environment and encourages the usage of alternative materials. Cellulose nanofibrils (CNF) are abundant and biodegradable, which makes them ideal candidates to replace plastic coatings. The ability to form H-bonds between the hydroxyl groups makes coated paper with CNF have good strength, but poor barrier properties. The barrier properties can be improved by grafting DMAEMA or HEMA onto CNF (CNF-g-PDMAEMA… More > Graphic Abstract

    Journal of Polymer Materials, Vol.42, No.1, pp. 141-150, 2025, DOI:10.32604/jpm.2024.057423 - 27 March 2025

    Abstract Geological samples often contain significant amounts of iron, which, although not typically the target element, can substantially interfere with the analysis of other elements of interest. To mitigate these interferences, amidoxime-based radiation grafted adsorbents have been identified as effective for iron removal. In this study, an amidoxime-functionalized, radiation-grafted adsorbent synthesized from polypropylene waste (PPw-g-AO-10) was employed to remove iron from leached geological samples. The adsorption process was systematically optimized by investigating the effects of pH, contact time, adsorbent dosage, and initial ferric ion concentration. Under optimal conditions—pH 1.4, a contact time of 90 min, and More >

    Urethral carcinoma after skin substitution urethral reconstruction

    Zhan Wu, Mystie Chen, Ryan Mori

    Canadian Journal of Urology, Vol.31, No.2, pp. 11858-11860, 2024

    Abstract Urethral cancer after urethral reconstruction is an under-recognized, uncommon disease associated with significant morbidity and mortality. The survival rates of patients with carcinoma of the bulbar urethra are as low as 20%-30%. Stricture recurrence and unrecognized malignant changes present prior to reconstruction are major risk factors for urethral cancer. Skin substitution urethroplasty is subjected to higher rates of recurrence, which lends to the potential for carcinogenesis. We present a case of a 59-year-old male who underwent multi-stage skin substitution urethroplasty who developed urethral carcinoma 20 years later. More >

    Abstract Dehydroabietyl polyethylene glycol glycidyl ether-grafted hydroxyethyl cellulose (HEC) polymer surfactant (DA(EO)5GE-g-HEC) was prepared using ring-opening polymerization with biobased rosin and hydroxyethyl cellulose as feedstocks. Dehydroabietyl polyethylene glycol glycidyl ether (DA(EO)5GE) was formed by condensation of dehydroabietyl alcohol polyoxyethylene ether (Rosin derivative: DA(EO)5H) and epichlorohydrin. The grafting degree of DA(EO)5GE-g-HEC was manipulated by adjusting the mass ratio of HEC and DA(EO)5GE and confirmed by EA. According to the formula, when m(HEC)/m(DA(EO)2GE) was 1:1~1:5, the grafting rate of DA(EO)5GE in DA(EO)5GE-g-HEC varied from 34.43% to 38.33%. The surface activity and foam properties of DA(EO)5GE-g-HEC aqueous solution were studied. The results showed that… More > Graphic Abstract
