Black titania by sonochemistry: A critical evaluation of existing methods.

In the field of photocatalysis, the fabrication of black titania is a booming topic, as it offers a system with improved solar light harvesting properties and increased overall efficiency. The darkening of white TiO powders can be ascribed to surface hydroxylation, oxygen vacancies, Ti centres, or a combination thereof. A handful of studies suggests these defects can be conveniently introduced by acoustic cavitation, generated during sonochemical treatment of pristine TiO powders.

The Impact of Systemic Oncological Treatments on the Fertility of Adolescents and Young Adults-A Systematic Review.

Background: Over the past decades, advancements in oncological treatments have led to major improvements in survival. Particularly for adolescents and young adults (AYAs), fertility is an important concern in cancer survivorship. The purpose of the review is to provide physicians with a practical overview of the current knowledge about the impact of systemic oncological treatments on the fertility of female and male AYAs.
