Item A facile fynthesis of ZnS nanostructures via liquid-solid reactions(Trans Tech Publications Ltd, 2014) Weerachon Phoohinkong; Thitinat Sukonket; Udomsak KitthaweeZinc sulfide (ZnS) nanostructures are important materials for many technologies such as sensors, infrared windows, transistors, LED displays, and solar cells. However, many methods of synthesizing ZnS nanostructures are complex and require expensive equipment. In this study, a liquid-solid chemical reaction without surfactant was used to synthesize ZnS at room temperature. In addition, commercial grade zinc oxide (ZnO) particles were used as a precursor. The effect of the addition of acids and inorganic salts were investigated. The products were characterized by field emission scanning electron microscopy (FESEM) coupled with energy-dispersive X-ray spectroscopy (EDX), and transmission electron microscopy (TEM). The results show that the nanoparticles of ZnS were obtained in hydrochloric acid and acetic acid addition. The diameters were in the range of 10 to 20 nm and 50 to 100 nm, respectively. In the case of a sodium chloride salt addition, a ZnS structure was obtained with a particle size of approximately 5 nm and a flake-like morphology. © (2014) Trans Tech Publications, Switzerland.Item A simple method for large-scale synthesis of nano-sized zinc sulfide(Trans Tech Publications Ltd, 2014) Weerachon Phoohinkong; Thitinat SukonketNano-sized zinc sulfide (ZnS) is a special property semiconductor material widely used in many applications such as catalyst, light emitting diode, transistor, gas sensors, biosensors, UV-light sensors, and photovoltaic cell. The wet chemical method is a simple and low-cost method to prepare nano-sized zinc sulfide. However, the wet chemical reaction using sodium sulfide without surfactant or template has rarely been reported. In the present work nano-sized zinc sulfide particles were synthesized by simple wet chemical reaction method at room temperature and without any surfactant. The influence of sulfur source, sodium sulfide and potassium sulfide used as the reactant were investigated. The samples were characterized by scanning electron microscopy coupling with energy-dispersive X-ray spectroscopy (FESEM-EDX), and transmission electron microscopy (TEM). The results show that the nanoparticles of zinc sulfide were obtained from sodium sulfide and potassium sulfide with particles sizes are in the range of 10 to 50 nm and 25 to 50 nm respectively. In addition, from FESEM microphotograph the primary ZnS particles size of around 5 nm and 25 nm were obtained by 10% salt (sodium chloride, potassium chloride, sodium acetate) addition with sodium sulfide and potassium sulfide reactant respectively. © (2014) Trans Tech Publications, Switzerland.Item Adsorbed protein on P25 nanoparticles-synthesis, characterization and electrochemical property(American Institute of Physics Inc., 2018) Weerachon Phoohinkong; Thitinart Sukonket; Kanokthip Boonyarattanakalin; W. Phoohinkong; Faculty of Science and Technology, Suan Dusit University, Bangkok, 10700, Thailand; email: p_veerachon@hotmail.comKeratin modification on surface of titanium dioxide P25 was carried out from titanium dioxide suspension and keratin solution extracted from swine wool. The existence of amide component, protein functional groups dissociated to active protein moieties and attached to titanium dioxide surface in form of hybrid nanomaterial were characterized by Fourier-transform infrared spectroscopy (FT-IR). The keratin protein decorated on particle surfaces was observed by Field Emission Scanning Electron Microscopy (FESEM). Chemical states and bonding at the nano-biomolecule interfaces with titanium dioxide were investigated using X-ray Photoelectron Spectroscopy (XPS). Protein concentration is considered as roles for protein modification, surface bonding, chemical states and protein adsorption. The Ti3+ and Ti2+ surface and high adsorption degree can be obtained at low concentration of protein solution with P25. However, the strong bonding between protein and TiO2 obtained in high protein concentration with Ti3+ and Ti2+ species result disappear for Ti3+ and Ti2+ XPS peaks. The adsorbed protein reveals secondary structure of random coil keratin with strong bonding conjugated to the titanium dioxide surface. The strong binding between protein and TiO2 surface in this novel protein-TiO2 hybrid material shows a promising alternative way for advance tunable electronic structure and charge transport mechanism which enhance electrochemical capacitance by mean of double layer and pseudo-capacitive behavior. � 2018 Author(s).Item Fortification of iron in brownies with sinlek brown rice flour(Prince of Songkla University, 2020) Tita Foophow; Weerachon Phoohinkong; Pipat Lertkowit; Natthakarn Ketkoom; T.

The applications of silica nanostructure frequently depend on physical properties such as morphology and size of structure. Rice husk ash is the waste from biomass power plants and is a high quality, raw material as a silica source. The conventional methods for synthesis of nano-silica from rice husk ash are energy consumption or time consumption. The objective of this work was to investigate the synthesized of nano-silica from rice husk ash via sodium silicate solution. Nano-silica particles were obtained via alkaline extraction and a fast acid precipitation method at room temperature by adding inorganic salts and without surfactant or template. The flow synthesis was investigated at ambient temperature, varying the concentration of hydrochloric acid, sodium chloride, and flow-rate while fixing the concentration of sodium silicate. The samples were characterized by field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). The results revealed that the sodium chloride is significantly inorganic salt for generated nano-silica, with uniform spherical morphology (80-150 nm), without curing or aging time. In the flow synthesis method, the silica nanoparticles, of diameter around 10 nm and aggregate particles of around 50 to 200 nm, were obtained. This method may be applicable to control different grade of silica and can easily scaling up of silica production for different industries. © (2014) Trans Tech Publications, Switzerland.Item Nonlocal XANES pre-edge feature of FeTiO3 ilmenite-type at Ti and Fe K-edge(Elsevier Ltd, 2020) Weerachon Phoohinkong; Kanokthip Boonyarattanakalin; Wanichaya Mekprasart; Sorapong Pavasupree; Wisanu Pecharapa; W. Pecharapa; College of Nanotechnology, King Mongkut's Institute of Technology Ladkrabang, Ladkrabang, 10520, Thailand; email: kpewisan@gmail.comThe pre-K-edge feature of Ti and Fe XANES of ilmenite FeTiO3 were investigated. The electronic structure of FeTiO3 was examined based on the partial density of electronic state distribution on both local and nonlocal atoms. A strong contribution of nonlocal metal-metal intervalence electronic states of Ti and Fe pre-K-edge was observed in X-ray absorption near-edge structure (XANES) measurement. This observation agrees well with the calculated local state density. The nonlocal excitation transitions in the pre-edge feature contribute to local pre-K-edge at both Ti and Fe. Ti pre-K-edge consists of highly hybridized Ti-3d(t2g) with a small part of dipole-allowed 4p and a small 4s density transition state feature which is predominated by nonlocal of Fe-3d mixed with 4p state delocalized via O-2p as the main component peak. The peak feature at Ti-3d(eg) energy state is assigned to hybridization of Ti-3d(eg) and Ti-4p state contributed with nonlocal of the hybridized Fe-sp and the Ti-pd state. Fe pre-K-edge shows two main prominent transition peaks of hybridized Fe-pd state and the delocalized local Fe-sp with nonlocal Ti-3d(t2g) and 4p mixing states centered at 7112.38 and 7116.48 eV, respectively. The local and nonlocal excited transition energy states and density of both Ti pre-K-edge and Fe pre-K-edge features are corresponded with each other through the O-2p state transition pathway. © 2020 Elsevier LtdItem Optical absorption and FTIR study of cellulose/tio2hybrid composites(Chiang Mai University, 2019) Kittiya Plermjai; Kanokthip Boonyarattanakalin; Wanichaya Mekprasart; Weerachon Phoohinkong; Sorapong Pavasupree; Wisanu Pecharapa; W.

The whole genome of KB111 strain was identified by DNA sequencing. Its produced protease was purified by salting out and anion-exchange chromatography, characterized based on protease activity and stability using a peptide substrate, and identified by LC-MS/MS. Results and conclusions. The strain KB111 was identified as Bacillus licheniformis. The molecular mass of its extracellular protease, termed KB-SP, was estimated to be 70 kDa. The optimal pH and temperature for the activity of this protease were 7 and 50 ¡C, respectively, while the enzyme exhibited maximal activity in the broad salinity range of 2Ð4 M NaCl. It was fully stable at an alkaline pH range of 7Ð11 at 50 ¡C with a half-life of 90 min. Metal ions such as K+, Ca2+ and Mg2+ could enhance the enzyme activity. Therefore, this protease indicates a high potential for the applications in the food and feed industry, as well as the waste management since it can hydrolyse protein at high alkaline pH and salt concentrations. The amino acid profiles of the purified KB-SP determined by LC-MS/MS analysis showed high score matching with the peptidase S8 of B. licheniformis LMG 17339, corresponding to the mature domain of a minor extracellular protease (Vpr). Amino acid sequence alignment and 3D structure modelling of KB-SP showed a conserved catalytic domain, a protease-associated (PA) domain and a C-terminal domain. Novelty and scientific contribution. A novel extracellular haloprotease from B. licheniformis was purified, characterized and identified. The purified protease was identified as being a minor extracellular protease (Vpr) and this is the first report on the halotolerance of Vpr. This protease has the ability to work in harsh conditions, with a broad alkaline pH and salinity range.

Phoohinkong; Faculty of Science and Technology, Suan Dusit University, Bangkok, 10300, Thailand; email: weerachon_pho@dusit.ac.thPhellinus linteus, a traditional medicinal mushroom, is highly valued for its health benefits. The commercially available fruiting body of Phellinus linteus (PL) was extracted and characterized to elucidate its potential nutritional bioactivity. A sequential extraction method was employed, starting with conventional ethanol extraction (PL-E), followed by mechanical ball-mill assisted ethanol extraction (PL-B) or supercritical CO2 cosolvent (PL-C), resulting in the identification of 19, 9, and 10 tentative compounds, respectively. The extracts comprised non-polar compounds, including triterpenoids and sterols in PL-E, and polyphenols and long-chain fatty acids in PL-B and PL-C. Hispidin and hispolon were found exclusively in PL-E. The PL-E demonstrated anticancer potential against MCF-7 cells, while the PL-C showed the highest activity against MCF-7 and HT-29 cells, suggesting that this high bioactivity fraction may be a promising candidate for anticancer studies. The PL-E, which exhibited high yield and bioactivity with various bioactive compounds, underwent complexation encapsulation with _-cyclodextrin. This study also proposes a potential green method to enhance these compounds' bioactivity value and bioaccessibility, supporting their development for food, nutraceutical, and pharmacological applications. © 2025Item Synthesis and characterization of copper zinc oxide nanoparticles obtained via metathesis process(IOP Publishing Ltd, 2017) Weerachon Phoohinkong; Tita Foophow; Wisanu Pecharapa; W.
