The Von Hippel Award, the Materials Research Society's highest honor, recognizes those qualities most prized by materials scientists and engineers—brilliance and originality of intellect, combined with vision that transcends the boundaries of conventional scientific disciplines. The Von Hippel Award is named after Arthur von Hippel (1898-2003), who was a pioneer in the study of dielectrics, semiconductors, ferromagnetics and ferroelectrics.

Eminent Scientist and Bharat Ratna Prof C.N.R. Rao was awarded 2017 Von Hippel Award. He is first Indian and first Asian to win this honour. The award will be presented to Prof Rao for his interdisciplinary contributions to development of novel functional materials, including nanomaterials, graphene, superconductivity, 2D materials and colossal magnetoresistance at Boston in November 2017.

The clotting of blood is a chain reaction initiated by the enzyme thrombokinase produced by the platelets. This causes prothrombin to be converted into thrombin in the presence of Ca++ion.

Thrombin combines with fibrinogen  to produce fibrin threads which entangles the corpuscles to form the clot.

Thiruvananthapuram also known as Trivandrum, is the capital and the largest city of the Indian state of Kerala is named after the snake Anantha of Lord Vishnu.

India has been placed in the second spot in the renewable energy country attractiveness index by EY. The UK accountancy firm noted the fast pace of growth in Indian renewable energy in the past three years. Over 10 gigawatt (Gw) of solar power was added between 2015 and 2017 and wind energy capacity grew to 5.4 Gw in 2017-18. This growth is in the context of the government’s ambitious targets — 175 Gw of renewables by 2022, with 40 per cent installed capacity from renewables by 2030 — and the dramatic price falls in photovoltaic technology.
