In this research, the chemical recycling of terephthalic acid from PET waste by using nano Fe3O4@Py-APTS as solid support was reported. The performance of organically modified nano magnetic was examined in detail and the results were compared with unsupported reactions as the model. By using the solid support, the required time for complete glycolysis, consumption of solvent and catalyst, decre...

A modified nanosphere lithographic method for producing arrays of silanized structures at silicon surfaces is described. Polystyrene (PS) particles (600 nm or 1000 nm in diameter) were self-assembled onto a silicon substrate to form a hexagonal close-packed pattern. The resultant patterned surface was then exposed to a solution of 3-aminopropyltriethoxysilane (APTS), which deposited gradually i...

Atopy patch tests (APTs) have been proposed for the diagnostic approach in children with non-IgE-mediated cow's milk allergy and gastrointestinal symptoms. We aimed to investigate the benefit of APTs in predicting oral tolerance in these patients. We prospectively evaluated 172 subjects with a sure diagnosis of non-IgE-mediated CMA and gastrointestinal symptoms (97 boys, 56.4%; age, 6.37 m; ran...

BACKGROUND We report on aminopropyltriethoxysilane (APTS)-mediated surface modification of nanohydroxyapatite with different surface functional groups for potential biomedical applications. In this study, nanohydroxyapatite covalently linked with APTS (n-HA-APTS) was reacted with acetic anhydride or succinic anhydride to produce neutralized (n-HA-APTS. Ac) or negatively charged (n-HA-APTS.SAH) ...

Both in linguistics and in speech technology phonetic transcriptions (PTs) are often needed. Given the many drawbacks in making manual PTs, researchers have been looking for ways to obtain PTs automatically. In this paper an overview is presented of automatic phonetic transcription (APT). Several aspects of APT are discussed: evaluation, generation and usability. Evaluation is needed to determi...

We report in vitro and in vivo magnetic resonance (MR) imaging of C6 glioma cells with a novel acetylated 3-aminopropyltrimethoxysilane (APTS)-coated iron oxide nanoparticles (Fe3O4 NPs). In the present study, APTS-coated Fe3O4 NPs were formed via a one-step hydrothermal approach and then chemically modified with acetic anhydride to generate surface charge-neutralized NPs. Prussian blue stainin...

This study examines the association between auditor-provided tax services (APTS) and financial reporting quality to determine if APTS impairs auditor independence or generates knowledge spillover. Lower (higher) financial reporting quality is generally viewed as evidence supporting auditor independence impairment (knowledge spillover). We use the quality of the income tax accrual estimate from ...

The authors discuss the Adult Playfulness Trait Scale (APTS), a measurement that they developed along with a conceptualization of playfulness based on a synthesis of personality research and play literature. They assert the research they conducted, which examined the nomological network of playfulness and involved relevant constructs of personality (self as entertainment), behavior (playing), a...

The molecular deposition of starch extracted from normal plants and transgenically modified potato lines was investigated using a combination of light microscopy, environmental scanning electron microscopy (ESEM) and confocal laser scanning microscopy (CLSM). ESEM permitted the detailed (10 nm) topographical analysis of starch granules in their hydrated state. CLSM could reveal internal molar d...

In this report, magnetic iron oxide nanoparticles were synthesized via coprecipitation of Fe2+ and Fe3+ with ammonium hydroxide, and the surface of synthesized nanoparticles was organically functionalized by commercially available amine coupling agent namely, 3-aminopropyl trimethoxysilane (APTS) by using well-known sol–gel method. Further reaction of the synthesized Fe3O4@APTS core-shell magne...
