    An Experimental Study and Analysis of Different Dielectrics in Electrical Discharge Machining of Al 6063 Alloy


    Journal of Polymer Materials, Vol.36, No.4, pp. 351-369, 2019, DOI:10.32381/JPM.2019.36.04.5

    Abstract Electrical discharge machining is a non-traditional machining processes in which it is based upon thermal and electrical energy source as an interval energy pulse discharge in-between the work piece and tool electrode so as to remove the material. A systematical investigation of melting and vaporising of aluminium to find the output responses such as Material removal rate (MRR), Electrode wear rate (Ra), and Surface finish (EWR) in EDM using two different dielectrics was conducted as experimental work. The working fluids are Polyethylene glycol (PEG 600) and kerosene. It is the hour of need to get the maximum MRR and surface… More >

    Songmei Liu, Yuheng Wu, Hongmei Li, Dongli Cai, Huiling Liang, Changchun Ye, Shenggen He*

    Phyton-International Journal of Experimental Botany, Vol.92, No.12, pp. 3267-3290, 2023, DOI:10.32604/phyton.2023.045453


    The consumption of cut roses (Rosa hybrida) has always ranked first in the world. However, it is vulnerable to rapid petal and leaf wilting due to leaf stomatal water loss, which seriously affects its ornamental quality and economic value. Stomatal movement, a key in plant physiological processes, is influenced by potassium and nitrate. Advancing comprehension of its physiological and molecular mechanism holds promise for preserving the freshness of cut roses. This study observed the impacts of different concentrations of KNO3 vase treatments on stomatal opening and water loss in cut rose ‘Carola’ leaves, as well as their transcriptional responses to… More >

    Laura Isabel Arias-Rodríguez1, Martha Alicia Rodríguez-Mendiola2,*, Carlos Arias-Castro2,*, Federico Antonio Gutiérrez Miceli1, Diana Reséndez Pérez3, María Celina Luján Hidalgo1, Juan José Villalobos Maldonado1, Norma Alejandra Mancilla Margalli2

    Phyton-International Journal of Experimental Botany, Vol.92, No.10, pp. 2807-2823, 2023, DOI:10.32604/phyton.2023.030396

    Abstract In recent years, there has been a growing interest in exploring alternative treatments for bone defects. Bone tissue engineering has turned its attention to plant extracts containing osteogenic flavonoids as potential promoters of bone regeneration. In our study, we specifically investigated the extract of Petroselinum crispum, a plant known for its abundance of osteogenic flavonoids such as apigenin, quercetin, and kaempferol. Our objective was to compare the total flavonoid content (TFC) and their accumulation in different sources. We obtained hydrolyzed aqueous extracts from the leaves of parsley plants (grown for 12 weeks in the field), weekly embryogenic cultures, and suspension… More >

    A Novel Parallel Computing Confidentiality Scheme Based on Hindmarsh-Rose Model

    Jawad Ahmad1,*, Mimonah Al Qathrady2, Mohammed S. Alshehri3, Yazeed Yasin Ghadi4, Mujeeb Ur Rehman5, Syed Aziz Shah6

    CMC-Computers, Materials & Continua, Vol.76, No.2, pp. 1325-1341, 2023, DOI:10.32604/cmc.2023.040858

    Abstract Due to the inherent insecure nature of the Internet, it is crucial to ensure the secure transmission of image data over this network. Additionally, given the limitations of computers, it becomes even more important to employ efficient and fast image encryption techniques. While 1D chaotic maps offer a practical approach to real-time image encryption, their limited flexibility and increased vulnerability restrict their practical application. In this research, we have utilized a 3D Hindmarsh-Rose model to construct a secure cryptosystem. The randomness of the chaotic map is assessed through standard analysis. The proposed system enhances security by incorporating an increased number… More >

    Journal of Renewable Materials, Vol.11, No.8, pp. 3245-3259, 2023, DOI:10.32604/jrm.2023.027461

    Abstract Biomass adhesive is conducive to decreasing the dependence of the wood adhesive industry on synthetic resin based on fossil resources and improving the market competitiveness of adhesives. It is also a critical breakthrough to realize the goal of carbon peaking and carbon neutrality in the wood industry. In this study, a full biomass wood adhesive composed of tannin and sucrose was developed and applied successfully to the preparation of plywood. The preparation technique of plywood was optimized, and the chemical structure, curing performance, crystallization property and thermal performance of the adhesive were investigated. Results showed that: (1) hot-pressing temperature played… More >

    Potential of Thai Bast Fibers for Injection Molded PLA Composites

    Nina Graupner1,*, Thiprada Poonsawat2, Koranat Narkpiban3,4, Jörg Müssig1

    Journal of Renewable Materials, Vol.11, No.5, pp. 2279-2300, 2023, DOI:10.32604/jrm.2023.025529

    Abstract Thailand has a huge variability of bast fiber plants, some of which have been little researched regarding their applicability in composites. Bast fiber(bundle)s from different species were investigated and incorporated into a polylactide (PLA) matrix by injection molding. Hemp and kenaf were used as well-studied fibers, while roselle, Fryxell and paper mulberry are less extensively characterized. Tensile strength, tensile modulus and interfacial shear strength (IFSS) of single fiber(bundle)s were highest for hemp, followed by kenaf, roselle, Fryxell and paper mulberry. Despite the lower tensile strength and IFSS of paper mulberry, the highest tensile strength was achieved for the paper mulberry/PLA… More > Graphic Abstract

    Lunzeng Huang1,2,#, Hongsheng Gao1,#, Ning Jiang1,2, Yunhong Xu1,2, Zijian Gong1,2, Lele Chen1,2, Shijie Xue1,2, Xiaoyan Li1, Ruichao Liu1,2, Bei Li1, Hongxia Zhang1, Chunyan Yu1,*, Xiaotong Guo1,2,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.2, pp. 349-368, 2023, DOI:10.32604/phyton.2022.025467

    Abstract Calcium (Ca2+) plays a pivotal role in various signal transduction pathways. Calcineurin B-like proteins (CBLs) are a unique group of Ca2+ sensors that decode Ca2+ signals by activating the plant specific protein kinase known as the CBL-interacting protein kinase (CIPK). In plants, the CBL-CIPK signaling network regulates multiple signals in response to different extracellular cues including abiotic stress. However, the genome wide annotation and expression patterns of CBLs and CIPKs in woody cutting flower plants are still unclear. In this study, a total number of 7 CBLs (RcCBLs) and 17 CIPKs (RcCIPKs) genes, divided into four and five subfamilies, respectively,… More >

    Thomas J. Nelson, Lindsey Bultema, Neal Eidenschink, Dean C. Webster*

    Journal of Renewable Materials, Vol.1, No.2, pp. 141-153, 2013, DOI:10.7569/JRM.2013.634113

    Abstract Bio-based polyols with high functionality were successfully synthesized by ring-opening epoxidized sucrose esters of soybean oil with methanol under acidic conditions, and were subsequently formulated with blocked isocyanates to form one package polyurethanes (1KPU). The bio-based polyols were characterized by gel permeation chromatography (GPC), Fourier transform infrared (FTIR) spectroscopy, proton nuclear magnetic resonance (1 H-NMR) spectroscopy, and Brookfi eld viscosity. Bio-based coatings were prepared by formulating the polyols with blocked polyisocyanates based on isophorone diisocyanate (IPDI) and hexamethylene diisocyanate (HDI). Two types of bio-based polyols were synthesized and the ratio of NCO:OH functional groups was varied to explore the effect… More >
