Hybrid Materials Obtained by Immobilization of Biosynthesized Ag Nanoparticles with Antioxidant and Antimicrobial Activity.

Ag nanoparticles (AgNPs) were biosynthesized using sage ( L.) extract. The obtained nanoparticles were supported on SBA-15 mesoporous silica (S), before and after immobilization of 10% TiO (Degussa-P25, STp; commercial rutile, STr; and silica synthesized from Ti butoxide, STb).

Effects of Aluminosilicate Gel Treatment and TiO Loading on Photocatalytic Properties of Au-TiO/Zeolite Y.

The present work reports the synthesis of efficient Ti-Au/zeolite Y photocatalysts by different processing of aluminosilicate gel and studies the effect of titania content on the structural, morphological, textural, and optical properties of the materials. The best characteristics of zeolite Y were obtained by aging the synthesis gel in static conditions and mixing the precursors under magnetic stirring. Titania (5, 10, 20%) and gold (1%) species were incorporated in zeolite Y support by the post-synthesis method.

Photocatalytic and Antibacterial Properties of Doped TiO Nanopowders Synthesized by Sol-Gel Method.

For environmental applications, nanosized TiO-based materials are known as the most important photocatalyst and are intensively studied for their advantages such as their higher activity, lower price, and chemical and photoresist properties. Zn or Cu doped TiO nanoparticles with anatase crystalline structure were synthesized by sol-gel process. Titanium (IV) butoxide was used as a TiO precursor, with parental alcohol as a solvent, and a hydrolysing agent (ammonia-containing water) was added to obtain a solution with pH 10.

Hearing the voices of children diagnosed with a life-threatening or life-limiting illness and their parents' accounts in a palliative care setting: A qualitative study.

Background: Exploring children's experiences of a life-threatening or life-limiting diagnosis is essential in offering appropriate care for them. There have been few studies examining these and they are often from the parent's perspective. Even if adults are frequently unwilling to share information with children, they become aware of their diagnosis and prognosis.
