Levan (Radboud University and University of Warwick) 27 October 2023 Sheffield astronomers help to confirm heaviest elements in the Universe are formed in kilonovae Astrophysicists are one step closer to understanding how the heaviest chemical elements are created in the universe, thanks to a camera designed and built at the University of Sheffield. Search Ejected stars do not just wander off into space, suggest researchers New research from the University of Sheffield has found that newly formed stars which are ejected from their birth region do not just wander off into space, but can interact with other star forming regions. 16 December 2020 When two become one: multiexcitonic triplet-pair intermediates in triplet-triplet annihilation We have directly measured time-resolved photoluminescence from multiexcitonic triplet-pairs and found that these intriguing states are directly formed during triplet-triplet annihilation in both exothermic and endothermic singlet fission systems. 11 December 2020 | Published by Nature Research Chemistry Community Study sheds new light on energy conversion in organic semiconductors The study helps to explain how high energy photons can be converted to pairs of low energy photons, and vice versa, through the processes of down-conversion and up-conversion. 11 December 2020 Two-dimensional magnets and semiconductors combine to reveal new technological possibilities The nanostructure is made out of atomically thin two-dimensional (2D) materials, which are similar to graphene but with different properties. 3 December 2020 Scientists make step towards the development of optical devices that enable control of photons The team were able to realise an effective magnetic field acting on photons in photonic graphene which enabled them to observe the optical version of the spin Hall effect. 1 December 2020 Pagination First page « First Previous page ‹ Previous … Page 7 Page 8 Page 9 Page 10 Current page 11 Page 12 Page 13 Page 14 Page 15 … Next page Next › Last page Last »
