Navigating Gravity: Competing Effects Result in Opposing Taxis for Different Janus Swimmers

Small, EarlyView.
The combined effects of gravity and wall‐induced hydrodynamics on the motion of Janus colloids are investigated. Platinum‐ and copper‐coated silica microswimmers show distinct gravitactic alignment near surfaces due to different hydrodynamic couplings. This distinct gravitactic behavior enables separation of initially mixed active particles.

Spectromicroscopy Analysis of Chicken Egg Shells

X-Ray Spectrometry, EarlyView.
ABSTRACT Chicken egg shells, taken from farm and backyard eggs of different suppliers from different regions in Brazil were collected for chemical/structural analysis, in order to try to find if there is a relation between egg shells composition and the type of production (farm or backyard), the egg shell color and the region of production.

Is the Eggshell Quality Influenced by the Egg Weight or the Breeder Age?

Brazilian Journal of Poultry Science
For a long time, it has been said that eggshell quality decreases as eggs increase in size, but this increase is seen as the breeder age advances. Therefore, the present study aimed to evaluate the age and egg weight effect on Cobb 500 broiler breeders ...
