The present study investigates the synthesis and analysis of zinc oxide nanoparticles (ZnO NPs) intended for use in electronic devices. ZnO NPs with an average crystallite size of 33 nm and a hexagonal wurtzite structure were produced by the combustion process. Scanning Electron Microscopy (SEM) revealed a densely packed, spherical morphology.

This work aims to investigate the mechanism of Pd nucleation and growth onto glassy carbon electrode from ChCl/urea/palladium mixture at room temperature using cyclic voltammetry (CV) and chronoamperometry (CA) techniques. Furthermore, X-ray diffraction, scanning electron microscopy and energy dispersive X-ray spectroscopy were used to examine the crystalline structure, morphology and compositions of deposited Pd samples.

In this work, SrFe12O19 samples were synthesized by hydrothermal method. We systematically studied the influence of an alkaline environment (NaOH) with the molar ratio (R) of 2 , 3 and 4 on the structure, magnetic properties of SrFe12O19 particles prepared by hydrothermal method. The relation between morphology, magnetic properties and microwave absorption properties of materials have been investigated.

This study aims to identify the relationship between the podium and the ways of using space in front of high-rise buildings on the coastal street Tran Phu, Nha Trang City. To achieve the above goal, the authors focused on analysing the architectural morphology of the podium and the space in front of the building, combined with comparing the types of podiums.

We provide the first country record of Opisthotropis durandi Teynié, Lottier, David, Nguyen & Vogel, 2014 from Vietnam based on a single snake specimen from Dien Bien Province. The species previously was only known from the Lao People’s Democratic Republic (Laos). DNA sequence data of a male specimen from Vietnam match those of a specimen of O. durandi from Phongsali province, Laos, and the newly collected individual from Vietnam also corresponds to O. durandi in terms of diagnostic morphological features, except for a slightly higher ventral number (185 versus 177−181).

A study on Mollusks’ species composition and distribution on dead coral from Quang Ngai to Cat Ba was conducted during the field survey between Vietnam and Russia on the AKADEMIC OPARIN RC vessel in 2021 at 39 reef stations in 14 study areas. By comparative morphology method, the authors have identified 135 taxa of Mollusca belonging to 48 families, 4 classes on coral reefs. The species composition of Mollusca was slightly different between study areas.

In this work, nano-SiO2 have been used as nanocarriers for loading Ce(III) ions (SiO2@Ce3+). After loading, silane coupling agent has been used to modify these nanocarriers (m-SiO2@Ce3+). Then, these modified nanocarriers were added as green inhibitors into the inner epoxy coating matrix, which was based on the epoxy resin (DER 671X75) and hardener (polyamide Epicure 3125). Morphological study by FE-SEM showed that the spherical nanoparticles (mSiO2@Ce3+) were in size < 100 nm and dispersed rather homogeneously into the polyme matrix.

Nano-hydroxyapatite/starch composite was synthesized using in situ precipitation. Starch concentration effect on the structure of composite was examined. Characterization of the obtained samples, The X-ray diffraction and Fourier transform infrared spectroscopy demonstrated the purity of the formed nano-HA in the starch matrix. Morphology studies of the samples, checked by field emission scanning electron microscope and transmission electron microscope, show the effects of starch on the size, shape, and morphology of hydroxyapatite nanoparticles.

In this study, achira (Canna edulis) starch was oxidized by sodium hypochlorite and the effects of different concentration of oxidation agent (1, 2, 3 and 5%) on the physicochemical properties, morphological properties and crystallinity of achira starch (AS) was investigated. The carbonyl and carboxyl content, starch colour parameters, swelling capacity, solubility, IR spectra, SEM and XRD of native and oxidized achira starch (OAS) were evaluated.

In this study, numerous Grateloupia spp. collected from coastal Vietnam and voucher specimens were used for morphological observation and phylogenetic analyses. Both analyses for samples collected at Nha Trang reveal a new record of G. yangjiangensis. The phylogenetic trees indicated that the herbarium vouchers labeled ‘G filicina’ and ‘G. livida’ from other locations of Vietnam group to G. yinggehaiensis clade. In addition, the phylogenetic trees also showed that the unknown Grateloupia sp. recently collected from Cat Ba Island is Phyllymenia taiwanensis. Therefore, a new record, G.

The identification of most species relied on careful examination of their morphological characters. These findings collectively raised the Ophichthus genus’s representation in Vietnamese waters by introducing three previously undocumented species, raising the total count to 17 compared to prior research. Furthermore, this study provides a comprehensive key to aid in identifying the various Ophichthus species found in Vietnam.

The present study focuses on the preparation of silver/copper bimetallic hybrid nanoparticles by green method from precursor solutions of silver nitrate & copper nitrate and the locally available citrus fruit (lemon) peel extract which behaves as the stabilizing and reducing agent. Initially, the formation of hybrid nanoparticles was noticed in the reaction mixture by colour change.

Ebook "Hox genes: Studies from the 20th to the 21st century" was intended as a listing of the kinds of naturally occurring variation that could act as a substrate for the evolutionary process and Bateson took his examples from collections, both private and in museums, of materials displaying morphological oddities. Interestingly the person who also coined the term “Genetics” proffered little in the way of speculation on the possible genetic underpinnings of these oddities.

The present study aims to identify Neofusicoccum isolates collected from lotus with symptoms of dieback, blight, and wilted leaves. Species were identified based on their morphology and comparison of the DNA sequence data for ITS rDNA and β-tubulin (tub-2). The taxonomy and phylogenetic relationships of pathogen isolates were investigated, and their pathogenic abilities were determined.
