    Bandana Padhan1,#, Rajkumar Patel2,#, Priyanka Bhowmik3, Ananya Roy1, Joyjyoti Das1,*, Yong Yu4,5, Madhumita Patel6,*

    Journal of Polymer Materials, Vol.42, No.2, pp. 411-433, 2025, DOI:10.32604/jpm.2024.059156 - 14 July 2025

    Abstract The food industry prioritizes food safety throughout the entire production process. This involves closely monitoring and evaluating all potential sources of biological or chemical contamination, starting from entering raw materials into the production chain and continuing to the final product. Biofilms on food surfaces or containers can harbor dangerous pathogens, such as Listeria monocytogenes. Therefore, it is essential to continuously manage microbial contamination on food contact surfaces to prevent foodborne infections. Recently, there has been increasing interest in using nanomaterials as surface coatings with antimicrobial properties in the food industry, especially since traditional disinfectants or antibiotics… More >

    Abstract Climate change, rising fuel prices, and fuel security are some challenges that have emerged and have grown worldwide. Therefore, to overcome these obstacles, highly efficient thermodynamic devices and heat recovery systems must be introduced. According to reports, much industrial waste heat is lost as flue gas from boilers, heating plants, etc. The primary objective of this study is to investigate and compare unary (Al2O3) thermodynamically, binary with three different combinations of nanoparticles namely (Al2O3 + TiO2, TiO2 + ZnO, Al2O3 + ZnO) and ternary (Al2O3 + TiO2 + ZnO) as a heat transfer fluid. Initially, three different types of… More > Graphic Abstract

    Performance Enhancement of Chitosan for Food Packaging: Impact of Additives and Nanotechnology

    Panji Setya Utama Putra1, Damar Rastri Adhika2,3,*, Lia Amelia Tresna Wulan Asri4, Suprijadi Suprijadi3,5

    Journal of Renewable Materials, Vol.13, No.6, pp. 1043-1070, 2025, DOI:10.32604/jrm.2025.02024-0002 - 23 June 2025

    Abstract The continuous increase in petroleum-based plastic food packaging has led to numerous environmental concerns. One effort to reduce the use of plastic packaging in food is through preservation using biopolymer-based packaging. Among the many types of biopolymers, chitosan is widely used and researched due to its non-toxic, antimicrobial, and antifungal properties. Chitosan is widely available since it is a compound extracted from seafood waste, especially shrimps and crabs. The biodegradability and biocompatibility of chitosan also showed good potential for various applications. These characteristics and properties make chitosan an attractive biopolymer to be implemented as food… More > Graphic Abstract

    Zinc Oxide Nanoparticles: Abiotic Stress Tolerance in Fruit Crops Focusing on Sustainable Production

    Meryam Manzoor1, Konstantin Korolev2, Maryam3, Riaz Ahmad4,*

    Phyton-International Journal of Experimental Botany, Vol.94, No.5, pp. 1401-1418, 2025, DOI:10.32604/phyton.2025.063930 - 29 May 2025

    Abstract The productivity of fruit crops is badly affected by abrupt changes in climatic conditions. It is a matter of concern for fruit tree researchers to feed the huge population within the available resources. The adverse effects of abiotic stresses are increasing due to fluctuations in climate change. Several abiotic stresses (salinity, drought, water logging, minerals deficiency, temperature extremities and heavy metals) are reducing the overall productivity of crops. Therefore, the application of different management approaches, i.e., phytohormones, nanoparticles, organic amendments, microbes and molecular aspects are effective for the mitigation of abiotic stresses in fruit crops.… More >

    Ferroptosis Mediates Zinc Toxicity: Implications for Cancer Therapy

    Anton Tkachenko*

    BIOCELL, Vol.49, No.5, pp. 721-741, 2025, DOI:10.32604/biocell.2025.063301 - 27 May 2025

    Abstract Ferroptosis is an iron-driven, phospholipid hydroperoxide-mediated cell death, which has recently emerged as an attractive tool in cancer research due to its ability to govern the anti-tumor immune response. A growing research interest in ferroptosis biology has revealed the contribution of this regulated cell death to multiple diseases. In addition to iron, ferroptosis has been reported to be triggered by multiple heavy metals, which sheds light on the novel aspects of heavy metals-induced cytotoxicity. In this review, the ability of zinc, an essential biogenic element with a wide array of biological functions, to modulate ferroptosis… More >

    Abstract In this research, the antibacterial properties of a composite material prepared from agave bagasse cellulose fibers doped with silver nanoparticles and chitosan were studied. The development of composite materials with antibacterial properties and environmentally friendly based on cellulose fibers from agave bagasse with silver nanoparticles prepared by green synthesis and chitosan from shrimp waste enhances the value of these agro-industrial wastes and offers the opportunity for them to have biomedical applications since these raw materials have been poorly reported for this application. The antibacterial properties of chitosan and silver nanoparticles are already known. However, the… More > Graphic Abstract

    Johanna Gaitán-Alvarez1, Róger Moya1,*, Alexander Berrocal1, Karla J. Merazzo1,2,3,4,5

    Journal of Renewable Materials, Vol.13, No.4, pp. 799-816, 2025, DOI:10.32604/jrm.2025.058755 - 21 April 2025

    Abstract The impregnation of nanoparticles magnetified into wood had been developed by different methods, like surface chemical coprecipitation and vacuum-pressure coprecipitation of magnetic nanoparticles (NPs). However, there is a lack of information on the best method to coprecipitation NPs. Then, the present study has the objective to measure the effects of the impregnation process of wood veneers through two in situ processes (immersion and vacuum-pressure) using a solution of FeCl3·6H2O, FeCl2·4H2O and ammonia in three tropical species (Pinus oocarpa, Vochysia ferruginea and Vochysia guatemalensis). It was measured the degree of synthesis of iron NPs using weight and density gains, Fe+3 absorption, emission… More > Graphic Abstract

    Abstract Oxygenated fuels can reduce harmful emissions without affecting engine performance, meeting the big challenge in the transportation industry, which keeps the environment safe and reduces global warming. This study investigates the impact of biodiesel injection strategies and fuel injection pressures (FIP) on diesel engine exhaust emission characteristics. The engine is fuelled with 20% Jatropha biodiesel (JB) and 80% diesel, named JB20D. The ratios of fuel injection pressures started with injecting the fuel (diesel and JB20D) from 200 bar to 500 bar. The experimental outcomes indicate that the engine performance of brake-specific fuel consumption increased by More > Graphic Abstract

    Jalil Ahmad1,*, Muhammad Munir2,*, Nashi Alqahtani2,3, Tahira Alyas4, Muhammad Ahmad5, Sadia Bashir6, Fasiha Qurashi7, Abdul Ghafoor8, Hassan Ali–Dinar2

    Phyton-International Journal of Experimental Botany, Vol.94, No.2, pp. 281-302, 2025, DOI:10.32604/phyton.2025.061534 - 06 March 2025

    Abstract A steady rise in the overall population is creating an overburden on crops due to their global demand. On the other hand, given the current climate change and population growth, agricultural practices established during the Green Revolution are no longer viable. Consequently, innovative practices are the prerequisite of the time struggle with the rising global food demand. The potential of nanotechnology to reduce the phytotoxic effects of these ecological restrictions has shown significant promise. Nanoparticles (NPs) typically enhance plant resilience to stressors by fortifying the physical barrier, optimizing photosynthesis, stimulating enzymatic activity for defense, elevating More >
