This article is aimed to investigate the syntactic and semantic properties of 2 intensive verbs in Thai, ‘pen’ and ‘khue’. It can be concluded that ‘khue’ is the equative identifying intensive verb, and there are 3 homonyms : ‘pen’(l) : the non-equative identifying intensive verb, ‘pen’(2) : the attributive intensive verb, and ‘pen’(3) : the comparative intensive verb.

<P><B>Abstract</B></P> <P>The development of low-cost and noble-metal-free catalysts for the photoconversion of water into hydrogen (H<SUB>2</SUB>) is of great interest. Here, 2D tin(IV) sulfide (SnS<SUB>2</SUB>) ultrathin nanosheets as co‐catalysts are coupled with 1D cadmium sulfide (CdS) nanorods for the photosplitting of water into H<SUB>2</SUB>. The design of the catalyst can facilitate the passivation of the physiochemical properties of CdS and enhance H<SUB>2</SUB> evolution activity. The prepared CdS/SnS<SUB>2</SUB> composite catalyst increases the H<SUB>2</SUB> generation activity and exhibits excellent and continuous long-term photostability. The H<SUB>2</SUB> evolution rate of the optimized CdS/SnS<SUB>2</SUB> composite is approximately 9-fold that of pristine CdS nanorods. The characterization results of the CdS/SnS<SUB>2</SUB> composite reveal that the loading of SnS<SUB>2</SUB> can enhance the synergistic effects of the photocatalyst due to the effective separation, large number of exposed catalytic sites, and highly dispersed nature of the layered SnS<SUB>2</SUB>. Several characterization outcomes of CdS/SnS<SUB>2</SUB> are examined in detail (e.g., structural and surface elemental results of transmission electron microscopy, X-ray diffraction analysis, X-ray photoelectron spectroscopy). Further, the optoelectrical properties and charge-carrier excitations are investigated via ultraviolet diffuse reflectance spectroscopy, photoluminescence spectroscopy, and photoelectrochemical analysis. The proposed CdS/SnS<SUB>2</SUB> composite is a promising low-cost, noble-metal-free, and high-efficiency catalyst for the photocatalytic water-reduction reaction.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Superior hydrogen evolution rate which is nine folds higher than the CdS. </LI> <LI> Excellent separation of photo generated charge carriers on CdS/SnS<SUB>2</SUB> hybrid with SnS<SUB>2</SUB> insertion. </LI> <LI> Excellent photo stability (30 h) of the catalyst for long term practical applications. </LI> <LI> Uniform deposition of ultrathin SnS<SUB>2</SUB> sheets onto CdS by simple methods. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>Optimal hydrogen evolution rate of 20.2 mmol h<SUP>−1</SUP> g<SUP>−1</SUP> facilitated by enhanced absorption and prolonged life time of charge carriers by SnS<SUB>2</SUB> as co-catalyst on CdS.</P> <P>[DISPLAY OMISSION]</P>

<P>In this paper a novel ligand debip (2-(4-N,N-diethylbenzenamine)1H-imidazo[4,5-f] [1, 10]phenanthroline) and its Ru(II) polypyridyl complexes [Ru(L)(2)(debip)](2+), (L = phen (1), bpy (2) and dmb (3)) have been synthesized and characterized by spectroscopic techniques. The DNA binding studies for all these complexes were examined by absorption, emission, quenching studies, viscosity measurements and cyclic voltammetry. The light switching properties of complexes 1-3 have been evaluated. Molecular docking, Density Functional Theory (DFT) and time dependent DFT calculations were performed. The Ru(II) complexes exhibited efficient photocleavage activity against pBR322 DNA upon irradiation and exhibited good antimicrobial activity. Also investigated 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) reduction assay, lactate dehydrogenase (LDH) release assay and reactive oxygen species (ROS) against selected cancer cell lines (HeLa, PC3, Lancap, MCF-7 and MD-MBA 231).</P>
