Researchers identifies Silicon as Undiscovered Element of Earth’s Core
i. Researchers from Tohoku University in Japan have claimed that they have discovered the unidentified element that formed the 5 percent of earth’s core after Iron and Nickel leading to new ways for better understanding of earths formation.
ii. According to the researchers, earth’s core is composed of 85 percent Iron, 10 percent Nickel and the rest 5 percent was composed of Silicon.
iii. To study the missing element, the researchers created a very high temperatures and pressures as found in the deep interior of the Earth.
iv. They then created alloys of iron and nickel and mixed them with silicon and subjected them to the immense pressures and temperatures that exist in the inner core. They discovered that the mixture matched with the Earth’s interior with seismic data.

Lightest Watch of the World made Using Graphene Launched
i. The world’s ultralight high-performance mechanical watch RM 50-03 was inaugurated on January 16, 2017 at the 27th edition of the Salon International De La Haute Horlogerie (SIHH) in Geneva.
ii. The watch made up of graphene composite has been developed by the University of
Manchester, UK in collaboration with the watchmaking brand Richard Mille and McLaren F1. The overall weight of the ultralight watch is 40 grams only and is extremely durable.
iii. The RM 50-03 watch was made using a unique composite incorporating graphene to manufacture a strong but lightweight new case to house the delicate watch mechanism.
iv. The graphene composite “Graph TPT” is very light weight as compared to previous materials used in watchmaking.
v. Besides the watch, the strap of the new watch has also been improved with the addition of graphene material. Grapheme was also injected into the rubber of the strap to improve its mechanical properties and its wear and tear properties.
Graphene
♦ Graphene is the world’s thinnest and lightweight material having the potential to enhance the quality of composites. Scientists and researchers have named it “a miracle material”.
♦ The presence of graphene can enhance the conductivity and strength of bulk materials and create composites that are conductive and resistant to heat and pressure.
