Genre analysis is one of the levels of discourse analysis in the light of Systemic Functional Linguistics. Martin (2007) proposed three strata in approaching discourse including the context of culture, situation, and discourse semantics (lexico-grammar). This paper examined the Generic Structure Potential (GSP) of Japanese precedents under the theory proposed by Hasan (1989) and then, provided some attention to characterizing other legal discourses.

The development a of highly efficient self-powered photodetector is a critical area of research for optoelectronic applications and the Internet of Things (IoT). In2S3 thin films grown using the spray pyrolysis technique were used rto develop self-powered photodetectors. The structural, optical, morphological, elemental, compositional and electrical characterization of the thin films were carried out for optimization.

In this work, the effect of annealing temperature and Cr3+ concentration on the structural and optical properties of the SnO2 host crystals has been investigated. The Cr-doped SnO2 samples were synthesized by a simple hydrolysis method, using SnCl4.5H2O as the host precursor and CrCl3.6H2O as the source of dopant.

A magnetic molecularly imprinted electrochemical sensor was developed for selective determination of sufentanil (SUF) based on carbon paste electrode (CPE) modified with methacrylic acid-ethylene glycol dimethacrylate-coated Fe3O4 nanoparticles (Fe3O4@MAA-EGDMA NPs). The structural properties, chemical structure, and electrochemical behaviors of the imprinted sensor were characterized by X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FT-IR), and square wave voltammetry (SWV), respectively.

In this research paper we report the detailed synthesis, spectral (1H-NMR, FT-IR, and UV-Vis), crystal structure determination, DFT studies, and molecular modeling of 4-amino-3-mercapto-5-methyl-1,2,4-triazole (L2) Schiff base ligand and its complexes of cadmium as suitable bioactive agents for the treatment of malaria. From the spectroscopic results, the synthesized Schiff base has potentialtridentate coordination with themetal ion via hydroxy naphthalinic-O, azomethine-N and sulphur atom of the thione group.

In this research, in an attempt to make use of the kaolin resources in Vietnam, we present a synthetic process of zeolite A via hydrothermal from kaolinite, together with the modification process of zeolite A using different metallic cations. The characteristics of the prepared zeolite LTAs such as chemical composition and crystalline structure, as well as their catalytic activity in the methanation reaction of carbon dioxide (CO2) to methane (CH4) were extensively investigated.

Cancer is the most destructive and fatal disease, representing an urgent medical challenge to the world. The discovery of a new anticancer candidate may help reduce or eliminate this alarming disease to a greater extent. On similar lines, in silico research was carried out on novel naphthylidene isoxazolidinedione derivatives that were logically conceived, synthesized, purified, and structurally characterized. In vitro biological evaluation revealed the most active compound 4d with an inhibitory concentration of 42.87 μM against K562 and 47.42 μM on A549 cells.

Structure, absolute configuration and cytotoxicity of compounds isolated from Decaschistia harmandii
In this work, we report the isolation and structure characterization of four compounds from ethyl acetate extract of the aerial part of D. harmandii for the first time. Especially, the absolute configuration of dimer stilbene ampelopsin F was successfully established upon circular dichroism (ECD) data. Besides, the cytotoxic properties of these compounds was also investigated on the cancer cell lines.

The plasmon characterization of AgNS on paper was systematically investigated by the diffuse reflectance spectroscopy. The fabricated paper-based SERS substrates were used to detect melamine in an aqueous solution and to determine the influence of type RAs on the enhancement factor (EF) and signal uniformity of SERS substrates. Among the four types of RAs, the SERS substrates used NaBH4 have the highest SERS signal with the limit of detection of 10-8 M for melamine and the EF = 2.3 × 109 .
