    Microstructural Evolution, Mechanical Properties and Corrosion Behaviors of Additively Manufactured Biodegradable Zn-Cu Alloys

    Bo Liu1,2,*, Jia Xie2, Gonghua Chen2, Yugang Gong2, Hongliang Yao1, Tiegang Li1

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.30, No.4, pp. 1-1, 2024, DOI:10.32604/icces.2024.012904

    Abstract Biodegradable metal implants that meet clinical applications require good mechanical properties and an appropriate biodegradation rate. Additively manufactured (AM) biodegradable zinc (Zn) alloys constitute an essential branch of orthopedic implants because of their moderate degradation and bone-mimicking mechanical properties. This paper investigated the microstructural evolution and corrosion mechanisms of zinc-copper (Zn-Cu) alloys prepared by the laser-powder-bed-fusion (L-PBF) additive manufacturing method. Alloying with Cu significantly increases the ultimate tensile strength (UTS) of unalloyed Zn, but the UTS and ductility of unalloyed Zn and Zn-2Cu decrease with increasing laser energy density. Unalloyed Zn has a dendritic microstructure,… More >

    Abhishek Kumar Patel, Ashlesha P. Kawale, Neeru Sharma, Nishant Shekhar, Subhash Banerjee*, Arti Srivastava*

    Journal of Polymer Materials, Vol.41, No.2, pp. 69-86, 2024, DOI:10.32604/jpm.2024.052695 - 09 August 2024

    Abstract This study aims to synthesize, characterize, and evaluate the photocatalytic efficiency of carboxymethyl cellulose (CMC) wrapped ZnONPs for the degradation of methylene blue (MB) dye under sunlight and also focuses on the effect of varying calcination temperatures on crystallite size of the synthesized ZnONPs@CMC. It focuses on developing biopolymer (CMC) wrapped ZnO nanoparticles (ZnONPs@CMC) at different calcination temperatures. ZnONPs@CMC are synthesized using zinc acetate dihydrate as a precursor under alkaline conditions, followed by adding capping agent CMC at various calcination temperatures ranging from 250°C to 650°C. The nanomaterials are characterized by UV-Vis, FTIR, and powder… More >

    Phyton-International Journal of Experimental Botany, Vol.93, No.5, pp. 901-922, 2024, DOI:10.32604/phyton.2024.049226 - 28 May 2024

    Abstract Garden pea productivity and qualities are hampered in zinc (Zn), boron (B), and molybdenum (Mo) deficient soil. Thus, the combination of micronutrients (i.e., Zn, B, and Mo) and rhizobium is necessary to increase the productivity and quality of garden peas, since this management for garden peas is neglected in Bangladesh. Therefore, the present study was made to assess the effectiveness of rhizobium inoculant singly or in combination with the micronutrients (i.e., Zn, B, and Mo) on growth, yield, nutrient uptake, and quality of garden peas. Treatments were: T = Control, T = Rhizobium inoculation at 50… More >

    Journal of Renewable Materials, Vol.12, No.2, pp. 369-380, 2024, DOI:10.32604/jrm.2023.046585 - 11 March 2024

    Abstract In this study, green zinc oxide (ZnO)/polypyrrole (Ppy)/cellulose acetate (CA) film has been synthesized via solvent casting. This film was used as supporting material for glucose oxidase (GOx) to sensitize a glucose biosensor. ZnO nanoparticles have been prepared via the green route using olive leaves extract as a reductant. ZnO/Ppy nanocomposite has been synthesized by a simple in-situ chemical oxidative polymerization of pyrrole (Py) monomer using ferric chloride (FeCl3) as an oxidizing agent. The produced materials and the composite films were characterized using X-ray diffraction analysis (XRD), scanning electron microscope (SEM), Fourier transform infrared (FTIR) and… More > Graphic Abstract

    Long non-coding RNA-ATB induces trastuzumab resistance and aggravates the progression of gastric cancer by repressing miR- 200c via ZNF217 elevation

    JIAZHUANG LI*, WEI ZHANG, SHOUBAO GAO, LI SUN, QINGYANG TAI, YING LIU

    BIOCELL, Vol.47, No.10, pp. 2313-2320, 2023, DOI:10.32604/biocell.2023.029860 - 08 November 2023

    Abstract Background: Trastuzumab resistance accounts for chemotherapy failure in gastric cancer patients in clinical practice. The significance of long non-coding RNAs (lncRNAs) in the maintenance of drug resistance in gastric cancer has been already underlined. Method: This study aimed to identify the specific role of lncRNA-ATB in gastric cancer progression and trastuzumab resistance. The downstream miRs of lncRNA-ATB and target genes of miRs were predicted by bioinformatics analysis and verified using dual luciferase reporter assay. Loss- and gain-function assays were performed to explore the roles of lncRNA-ATB, miR-200c, and zinc-finger protein 217 (ZNF217) in the cell functions More >

    Phyton-International Journal of Experimental Botany, Vol.92, No.8, pp. 2461-2471, 2023, DOI:10.32604/phyton.2023.029920 - 25 June 2023

    Abstract Aromatic and medicinal plant species having small seeds have field emergence problems due to low nutrient supply. Therefore, Pimpinella anisum seeds were hydro and osmoprimed with 100 mM MgCl2, CaCl2, and ZnCl2, for 2, 4, and 8 h each to compare their growth attributes during germination and seedling establishment stages. Nontreated seeds were used as control. Both hydro and osmo primed seeds were dried for 48 h before, they were sown in plastic trays in growth room conditions to see the impact of treatments on seedling emergence and growth. The maximum root length (12.90 cm), fresh weight (256.30… More >

    Fatiha Daoudi1,*, Abdelkrim Naas1, Omar Meglali1,2, Radia Boudaira3, Ahmed Gueddim1, A. M. Saeed4

    Energy Engineering, Vol.120, No.8, pp. 1803-1815, 2023, DOI:10.32604/ee.2023.028423 - 05 June 2023

    Abstract The numerical simulations were performed using the AMPS-1D simulator to study the effects of the CZTS as an absorber layer and the contacts’ barrier height on the performance of four ZnO/CdS/CZTS solar cells. To obtain the best cell performances, the barrier heights of the back and front contacts were adjusted between 0.01, 0.77, 0.5, and 1.55 eV, respectively. For simulations, we used the lifetime mode, and the device performances were evaluated under AM1.5 illumination spectra. We found that the efficiency, fill factor, and open-circuit voltage were almost constant at a front contact barrier height of… More > Graphic Abstract

    Abstract Zinc-finger proteins play different roles in cancer; however, the function of zinc-finger protein ZNF575 in cancer remains unclear. In the present study, we aimed to determine the function and expression of ZNF575 in colorectal cancer. Proliferation assay, colony formation assay, and tumor model in mice were used to investigate the function of ZNF575 after ectopic expression of ZNF575 in colorectal cancer (CRC) cells. RNA sequencing, ChIP, and luciferase assays were used to investigate the mechanism behind ZNF575 regulation of CRC cell growth. The expression of ZNF575 was determined by IHC staining in 150 pairs of… More > Graphic Abstract

    Abstract Background: Cardiomyocytes derived from human embryonic stem cells (hESCs) are regulated by complex and stringent gene networks during differentiation. Long non-coding RNAs (lncRNAs) exert critical epigenetic regulatory functions in multiple differentiation processes. However, the involvement of lncRNAs in the differentiation of hESCs into cardiomyocytes has not yet been fully elucidated. Here, we identified the key roles of ZFAS1 (lncRNA zinc finger antisense 1) in the differentiation of cardiomyocytes from hESCs. Methods: A model of cardiomyocyte differentiation from stem cells was established using the monolayer differentiation method, and the number of beating hESCs-derived cardiomyocytes was calculated.

    Impact of ZnSO and ZnO Nanoparticles on Seed Germination and Seedling Growth of Lettuce

    Adalberto Benavides-Mendoza1, Rebeca Betancourt-Galindo2, Nazario Francisco-Francisco3,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.6, pp. 1831-1840, 2023, DOI:10.32604/phyton.2023.028085 - 11 April 2023

    Abstract

    Micronutrient nanoparticles (NPs) are currently an option for chemical fertilization and biostimulation in crops. However, there is little information on the phytotoxic or biostimulatory effects of NPs at low concentrations of some elements, such as Zn. In this study, the effect of low concentrations of Zn oxide (ZnO) NPs on germination, growth variables, and nutritional attributes of lettuce (Lactuca sativa L.) was evaluated in comparison to Zn sulfate. Romaine lettuce seeds were treated with ZnSO4-- × 7H2O and ZnO NPs at Zn molar concentrations of 1 × 10−3, 5 × 10−3, 1 × 10−4, 5 × 10−4, 1
