The Emerging Perovskite Photovoltaics | ScienceMonk

The term “perovskite” was first used by Gustav Rose in 1839 when he discovered a new material based on Calcium Titanate (CaTiO3). He named this material “perovskite” after the Russian mineralogist Lev Von Perovski. The concept of perovskites was then changed to any material having a composition ABX3, and, since then, there have been a large number of discoveries of materials with the same composition. One of these has been halide perovskites based on caesium and lead.

Forensic Entomology: The Use Of Insects In Criminal Investigations

Forensic Entomology is a sub-field of forensic biology. It applies the knowledge of the field of entomology to identify, collect, and study the type of insects found in close proximity of the cadaver in solving cases of crimes. In this, the biology and ecology of insects are studied to determine the time since death or post-mortem interval.

Asphalt: Everything You Need To Know | Bitumen | ScienceMonk

Asphalt, also known as bitumen, is a refined semi-solid product of petroleum. Also found in natural deposits, It occurs as a black viscous liquid. The asphalt which naturally occurs is commonly called as “crude bitumen,” whereas the asphalt obtained by fractional distillation of crude oil at 525 degrees Celcius is referred to as “refined bitumen.”

Environmental Toxicology- Study of Toxicants present In the Atmosphere

Environmental Toxicology deals with the effects of environmental toxicants on health as well as the environment. The word ‘health’ refers to that of both humans, animals, and plants as well as the other abiotic components of the environment. Environmental toxicology is thus concerned with how environmental toxicants, through their interaction with humans, animals, and plants, influence the health and welfare of these organisms.
