In this study, phenol-formaldehyde (PF) resin has been modified with titanium dioxide nanoparticles (nano-TiO2) at a varying ratio from 0.05 wt.% to 1.5 enhance the thermal properties and combustion performance of resins. The effect nano-TiO2 modification on (chemical or thermal) resins was determined by Fourier transform infrared (FT-IR) analysis (TGA) techniques. addition, laminated veneer lu...

The immobilization of titanium dioxide is necessary for several energy and environmental applications such as dye-sensitized solar cells (DSSCs). A two-step fabrication route has been developed in this work including a near room temperature hydrolysis reaction to produce immobilized (NH4)2TiOF4 arrays, followed by successive topotactic transformations immobilised TiO2 mesocrystals (imcTiO2). Hi...

The effectiveness of photocatalytic processes is dictated largely by plasmonic materials with the capability to enhance light absorption as well as the energy conversion efficiency. Herein, we demonstrate how to improve the plasmonic photocatalytic properties of TiO2/Al nano-void arrays by overlapping the localized surface plasmon resonance (LSPR) modes with the TiO2 band gap. The plasmonic TiO...

Nano-layered sorbents for CO(2) capture, for the first time, were developed using layer-by-layer nanoassembly. A CO(2)-adsorbing polymer and a strong polyelectrolyte were alternately immobilized within porous particles. The developed sorbents had fast CO(2) adsorption and desorption properties and their CO(2) capture capacity increased with increasing nano-layers of the CO(2)-adsorbing polymer.

Fe-TiO2 on granular activated carbon support was synthesized via hydrothermal method without calcination. The crystalline phases were identified using X-ray diffraction whereas the surface morphologies were examined using scanning electron microscopy. Peaks of anatase TiO2 and graphite were present in the Fe-TiO2-GAC sample. Comparisons of the surface features of GAC and Fe-TiO2-GAC show that F...

Interfacial electron injection from a photoexcited surface-immobilized dye to semiconductor substrate is key reaction for dye-sensitized photocatalysts. We previously reported that the molecular orientation of heteroleptic Ir(III) photosensitizer on TiO2 nanoparticle surface was important efficient interfacial injection. In this work, overcome weak light absorption ability and improve photoindu...

An estimated 1% or less of nanoparticles (NPs) deposited in the lungs translocate to systemic circulation and enter other organs; however, this estimation may not be accurate given the low sensitivity of existing in vivo NP detection methods. Moreover, the biological effects of such low levels of translocation are unclear. We employed a nano-scale hyperspectral microscope to spatially observe a...

Nanomaterial production is expanding as new industrial and consumer applications are introduced. Nevertheless, the impacts of exposure to these compounds are not fully realized. The present study was designed to determine whether gestational nano-sized titanium dioxide exposure impacts cardiac and metabolic function of developing progeny. Pregnant Sprague-Dawley rats were exposed to nano-aeroso...

To improve the durability performance of recycled aggregate concrete in actual use, this paper uses nano-TiO2-modified coarse to study, through experiments, effects nano-TiO2 on pore distribution after freeze–thaw. The capillary-water-absorption law was used as evaluation index. prepared with different contents nano-TiO2, and changes 24 h capillary water absorption porosity freeze–thaw cycles w...
