Green fabrication of silver imprinted titania / silica nanospheres as robust visible light-induced photocatalytic wastewater purification

Publication date: 1 February 2020Source: Materials Chemistry and Physics, Volume 241Author(s): Ziyad A. Alrowaili, Ibrahim Hotan Alsohaimi, Mohamed A. Betiha, Amr A. Essawy, Ahmed A. Mousa, Saif F. Alruwaili, Hassan M.A. HassanAbstractHerein, the Inexpensive Phyto-synthetic approach using green tea extract to fabricate silver greenly imprinted TiO2 nanoparticles modified mesoporous silica nanocomposite (Ag/TNPs-MSNs) is reported. The nanocomposites were featured by using UV–vis diffuse reflectance spectra, X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), nitrogen Sorption, High-resolution transmittance electron microscopy (HRTEM) and Field Emission Scanning Electron Microscopy (FESEM). Ag/TNPs-MSN bandgap evaluations are 2.78 eV compared to 3.16 eV for TNPs-MSNs with ideal visible light capture capability, indicating the outstanding photodegradation activity of the synthesized nanocomposite. In addition, Ag/TNPs-MSNs photocatalytic effectiveness is evaluated in the degradation of aqueous solutions enriched with methylene blue (MB). The composite materials are extremely appropriate based on stability, recyclability/reusability, and a proper approach for visible-light-degradation of MB from the contaminated waters.Graphical abstract

ConclusionsThis study provides information about Aβ plaque burden, tau tangle burden, and neurodegeneration in cognitively unimpaired persons at three levels of genetic risk for AD. Unimpaired APOE ϵ4 HMs can be studied before their 70s to evaluate the understanding of factors, processes, and interventions involved in the predisposition to and prevention of AD, and after their 70s, to discover factors, processes, and interventions involved in the resilience or resistance to and prevention of AD.

CONCLUSIONS: PD-L1 inhibitors lead to immune mediated thyroiditis, the most frequent endocrine IRAE. In most cases, management is supportive without requiring steroids or discontinuation of immunotherapy. Diffusely increased thyroid 18FDG uptake on PET scan may predict the occurrence of thyroiditis, whereas TPO antibodies may help identify its severity. Thyroiditis may be a biomarker for anti-tumor immune response, highlighting the need to further characterize its underlying mechanism. PMID: 31813343 [PubMed - as supplied by publisher]

Angelol B is one of the bioactive constituents of APR with significant anti-inflammatory activity. This paper is aimed to illustrate the metabolites of angelol B in vivo. To achieve this objective, a metabolomics approach based on a rapid and accurate UPLC-Q-TOF-MS method was used to detect th...

CONCLUSIONS: We summarized the current tendency and limitations as well as future challenges in this field. The development of CAD needs to meet the rigid clinical requirements, such as high accuracy, strong robustness, high efficiency, fine-grained analysis and classification, and to provide practical clinical functions. This review provides helpful information for both engineering researchers and radiologists to learn the latest development of CAD systems. PMID: 31815727 [PubMed - as supplied by publisher]

This study presents an exploratory characterization on the effect of build orientation on deformation behavior of Ti–6Al–4V rods produced through electron beam melting (EBM). Microstructural differences in horizontally and vertically printed rods were characterized using optical microscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) coupled with energy dispersive spectroscopy (EDS), and electron backscatter diffraction (EBSD). A typical microstructure of the alloy consists of primary-α and vanadium-enriched β-phases. Compared to the horizontal samples, vertically print...
