Scientists successfully visualized crystal nucleation

A team at UNIGE has succeeded in visualizing crystal nucleation - the stage that precedes crystallization - that was invisible until now.

Пермские химики разрабатывают составы для замедления коррозии нефтяных труб
 Ученые Пермского государственного национального исследовательского университета (ПГНИУ, участник НОЦ «Рациональное недропользование») работают над созданием защитных составов, которые позволяют снизить скорость коррозии металла более чем на 90%. Например, если скорость коррозии металлической трубы в нефтяной скважине составляет 10 мм/год, то после добавления ингибитора она сократится до 1 мм/год.

Life May Have Become Cellular by Using Unusual Molecules

Life may have become cellular by using unusual molecules

 E-Mail IMAGE: Starting from a liquid alpha hydroxy acid monomer library, drying through heating results in synthesis of polyester polymers, which form a gel-like state. This gel is then rehydrated, resulting in. view more  Credit: Tony Z. Jia All modern life is composed of cells, from single-celled bacteria to more complex organisms such as humans, which may contain billions or even trillions of cells, but how life came to be cellular remains uncertain. New research led by specially appointed assistant professor Tony Z. Jia at the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology, along with colleagues from around the world (Japan, Malaysia, France, Czech Republic, India and the USA), shows that simple chemical compounds known as hydroxy acids, which were likely common on primitive Earth, spontaneously link together and form structures reminiscent of modern cells when dried from solution, as may have happened on or in ancient beaches or puddles.
