Global restriction of using antibiotic growth promoters and alternative strategies in poultry production

Posted on 24. April, 2018.

The use of antibiotics in animal and poultry feed has been a global practice since the middle of the last century. Antibiotics are used both at therapeutic and subtherapeutic levels to promote growth and feed efficiency. However, judicial use of antibiotics in food animals for growth promotion and disease prevention has been controversial for a long time due to the development of antibiotic resistant bacteria in animals and humans, resulting in treatment failure when needed.

Perovskites and their potential use in solar energy applications - Free Current Commentary

Posted on 16. September, 2014.

A material may be described as having a perovskite structure if it has same type of crystal structure as perovskite – calcium titanium oxide (CaTiO3) – does (Figure 1). Perovskite was first discovered in 1839 by Gustav Rose, in the Ural mountains in Russia, and is named after the Russian mineralogist L.A. Perovski (1792 –1856), who first characterised the material.
