The Perovskite Boom - Scientific American
The first perovskite solar cell PSC had such a low efficiency rate—an uninspiring 3.8 per cent—that several leading science journals rejected Miyasaka’s paper presenting the results.
Making and Breaking of Lead Halide Perovskites
means to improve perovskite solar cell performance should not be underestimated. Within the hybrid perovskite lattice organic ions can undergo crystal phase-dependent reorientation.11 In contrast to inorganic perovskites these molecular ions often exhibit permanent molecular dipoles 2.3 D for gas phase CH 3 NH 3

Validation of a Method for Extracting Microplastics from .
Complex and organic-rich solid substrates such as sludge and soil have been shown to be contaminated by microplastics; however methods for extracting plastic particles have not yet been systemically tested or standardized. This study investigated four main protocols for the removal of organic material during analysis of microplastics from complex solid matrices: oxidation using H2O2 Fenton .

Hydrocyclones - an overview ScienceDirect Topics
A hydrocyclone can handle very high slurry throughput rates and often an entire battery of hydrocyclones can be found at a mineral processing facility. The advantage of fast processing by a hydrocyclone is somewhat offset by the associated high impingement wear rate of the hydrocyclone internal surface lining by the fast-moving abrasive slurries.
