Short video platforms are growing rapidly, and users often use them to get an overview before deciding. videos a unique tool for tourist marketing because of the amount content on tourism, which is believed significantly impact information dissemination travel decision-making (Li & Hayes, 2024). Therefore, primary objective this study was examine factors that influence Generation Z’s impulsive decisions by watching short videos. 280 individuals with prior experience brief were recruited...
This paper presents our recent research results on synthesis and bioapplications of dye-doped silica-based nanoparticles. The water soluble organically modified silicate (ORMOSIL) nanoparticles (NPs) with the size 15–100 nm were synthesized by Stöber method from methyltriethoxysilane CH3Si(OCH3)3 precursor (MTEOS). Because thousands fluorescent dye molecules are encapsulated in matrix, extremely bright photostable. Their surfaces bovine serum albumin (BSA) biocompatible chemical reagents....
This paper presents a summary of our results on studies synthesis and biomedical application optical nanoparticles. Gold, dye-doped silica based core–shell multifunctional multilayer (SiO2/Au, Fe3O4/SiO2, Fe3O4/SiO2/Au) water-monodispersed nanoparticles were synthesized by chemical route surface modified with proteins biocompatible reagents. The particles conjugated antibody or aptamer for specific detecting imaging bacteria cancer cells. photothermal effects gold nanoshells (SiO2/Au cells...
Tagitinin C, a sesquiterpene lactone compound from Tithonia diversifolia, is known to have various bioactivities including anticancer effects. The disadvantages of tagitinin C which make its therapeutic application limited are low water solubility and poor stability. In this work, we encapsulated in the form liposomal nanoparticles overcome limitations evaluated activity. Liposomes were prepared using phosphatidylcholine, tween 80 with/without T. diversifolia pectin. liposomes exhibited...
Abstract This work reports a green method to synthesize pectin‐capped selenium nanoparticles (PT‐SeNPs) using ascorbic acid as reductant under mild conditions. Pectin was extracted from Tithonia diversifolia (Hemsley) A. Gray plant. played the role of capping agent preventing agglomeration nanoparticles. The synthesized PT‐SeNPs were characterized by UV–Vis spectrophotometry, EDX spectroscopy, TEM, DLS, FT‐IR, XRD, and TG‐DTA. TEM DLS techniques revealed monodispersed spherical with sizes...
Organically modified silicate (ORMOSIL) nanoparticles (NPs) doped with rhodamine 6G and B (RB) dyes were synthesized by Stöber method from methyltriethoxysilane CH3Si(OCH3)3 precursor (MTEOS). The NPs are surface functionalized cationic amino groups. optical characterization of dye-doped ORMOSIL was studied in comparison that free dye solution. used for labeling bacteria E. coli O157:H7. number have been counted using the fluorescent spectra microscope images labeled bacteria. results show...
Solanum procumbens L. (Solanaceae) were extracted respectively with n-hexane, ethyl acetate, and methanol to obtain the corresponding extracts. The methanol-soluble extract was acidified by adding HCl 0.5M; this followed liquid-liquid partition CHCl3 afford CHCl3-soluble fraction. From fraction, four compounds isolated identified as ergosterol peroxide (1), 9,11-dehydroergosterol (2), N-(N-benzoyl-L-phenylalanyl)-L-phenylalanol (3), moupinamide (4). Their structures elucidated based on NMR...
Abstract Silicon nanowires were successfully synthesized by a thermal evaporation method. We have observed strong and broad emission band centered at 670 nm, which is attributed to the quantum confinement effect related Si nanostructures embedded in complex SiO x matrix. By fitting an experimental Raman spectrum, we confirm that as-received wires possess crystalline silicon cores whose sizes around 5 nm. Furthermore, abnormal dependence of integral photoluminescence intensity on measured...

Our proposed uses various multimode interference (MMI) couplers, symmetric Y-junctions, and thermo-optic phase shifters. The suggested working principle is proved theoretical analysis about transfer matrix relation. optimization of geometrical parameters metallic micro-heaters executed...
In this work, a polysaccharide from Tithonia diversifolia (TDP) was extracted and selenized to obtain Se-TDPs derivatives. Structural properties of TDP were characterized using HPLC, NMR, AAS, GPC, FT-IR, ESI-MS. determined be pectic with branched arabinan in the side chains. The FT-IR MS spectra indicated new peaks on comparison that TDP. Moreover, suggested selenyl groups substituted backbone molecules instead Selenized-TDP (Se-TDP) samples exhibited significant cytotoxicity human gastric...
