AI Article Synopsis
- The study focuses on improving the qualities of mangium wood, which grows rapidly in Indonesia, by using titanium dioxide (TiO) nanoparticles through an impregnation method.
- The researchers produced TiO nanoparticles via a hydrothermal method and tested how different concentrations (1% and 5%) impacted the wood's density and stability.
- Results showed that TiO nanoparticle treatment increased the wood's density, weight percent gain, and bulking effect while also enhancing its ability to degrade pollutants, offering better protection against UV radiation.
Article Abstract
Mangium ( Willd.) is a fast-growing wood that is widely grown in Indonesia. The impregnation method is needed to improve the qualities of the wood. In this study, TiO nanoparticle (79.17 nm) was produced using the hydrothermal method. The purpose of this study was to analyze the effect of TiO nanoparticle impregnation on the density and dimensional stability of mangium and the effectiveness of the presence of TiO nanoparticle in wood in degrading pollutants. The mangium samples (2 cm × 2 cm × 2 cm) were placed inside impregnation tube. The impregnation solutions included water (untreated), 1% TiO nanoparticle, and 5% TiO nanoparticles. The samples were analyzed for density, weight percent gain (WPG) dan bulking effect (BE). Samples were also analyzed by X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). TiO nanoparticle resulted in an increase in density, WPG, and BE-treated mangium. Based on XRD and FTIR results, TiO nanoparticle was successfully impregnated into mangium wood. Scanning electron microscopy-energy-dispersive X-ray spectroscopy analysis indicated that TiO nanoparticle covered the surface of the wood cells. The TiO-impregnated mangium wood has a higher photocatalyst activity than untreated, indicating better protection from UV radiation and pollutants.

In this present investigation, plant-mediated synthesis of titanium oxide (TiO) nanoparticles was synthesized from seagrass (Thalassia hemprichi) using the hot plate combustion method (HPCM). Synthesized TiO nanoparticles optical, functional, structural, and morphology properties were analyzed by UV-visible spectroscopy, Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). SEM analysis confirmed the spherical shape of the TiO nanoparticles were observed in various sizes, viz.

The aggregation state of nano-TiO in the environment is altered under marine heatwaves (MHWs), thus affecting its bioavailability and toxicity to the marine organisms. Here, we investigated the toxic mechanisms and effects of nano-TiO on gut-hepatopancreas axis health of Mytilus coruscus exposed to 25 and 250 μg/L of nano-TiO under laboratory-simulated MHW. Compared with the control conditions or post-MHW cooling phase, prolonged MHW exposure significantly inhibited digestive function, decreased immune-related enzymes activities, and caused neurotoxicity in the mussels.

Emerging contaminants in estuarine sediments, such as bis(2-ethylhexyl) phthalate (DEHP) and titanium dioxide nanoparticles (nTiO), pose ecotoxicological risks that may be exacerbated by co-contamination. This study investigated the impacts of DEHP, nTiO, and their combinations at environmentally relevant concentrations (1, 10, and 100 μg/g) on the soil nematode Caenorhabditis elegans in estuarine-like sediment (14.25‰ salinity).

Despite the potential of sonodynamic therapy (SDT) in treating malignant tumors, the lack of effective sonosensitizers has limited its clinical implementation. In this study, we explored the relationship between the heteroatom doping concentration in metal-organic frameworks and interface formation after pyrolysis by regulating the addition of manganese sources and successfully derived Z-scheme heterojunctions MnO/(A/R)TiO (MTO) in situ from MIL-125-NH (Ti/Mn). The electron transfer pathway introduced by interfacial contact promoted carrier separation and greatly preserved the effective redox components, significantly influencing the performance of reactive oxygen species generation.

Alzheimer's disease (AD) is the most common dementia in humans that today concerns 50 million individuals worldwide and will affect more than 100 million people in 2050. Except for familial AD cases (<5% of AD patients) for which AD pathology connects to mutations in critical genes involved in the processing of the amyloid precursor protein into neurotoxic Aß peptides, it remains unknown what provokes the overproduction and deposition of Aß peptides in the brain of sporadic AD cases (>95% of AD patients). Some nanosized materials, e.
