Scientists at Nanyang Technological University in Singapore (NTU Singapore) have discovered a way to make biocement from trash, making it a greener and more sustainable alternative to ordinary cement. Biocement is a type of renewable cement that binds soil into a solid block by using bacteria to induce a hardening reaction. Biocement has now been
According to a study, devices made of commonly available oxide and carbon-based materials can manufacture pure hydrogen from water for weeks. The discovery could aid in overcoming one of the major challenges in solar fuel production: present earth-abundant light-absorbing materials are limited in terms of performance or stability. The move to full decarbonisation and the
Astronomers have detected two big, unexplained objects erupting from the universe’s brightest black hole. The supermassive black hole 3C 273 was discovered in a 1959 survey of cosmic radio-wave sources as a quasar (quasi-stellar object). The light emitted by these black holes is brilliant enough to be mistaken for starlight. Scientists have spent decades studying
