NUS researchers successfully integrated a new anion, cyanate, into a perovskite structure, which was a key breakthrough in fabricating new triple-junction perovskite/Si tandem solar cells. Credit: National University of SingaporeResearchers at the National University of Singapore (NUS) have developed a novel triple-junction perovskite/Si tandem solar cell that can achieve a certified world-record power conversion efficiency of 27.1 percent across a solar energy absorption area of 1 sq cm. This achievement marks the…

Scientists have developed a new photocatalytic method for producing hydrogen peroxide using water and air, employing a novel covalent organic framework. This method is energy-efficient and environmentally friendly, contrasting sharply with the traditional, more hazardous anthraquinone process.Scientists at the National University of Singapore (NUS) have created a microporous covalent organic framework with dense donor–acceptor lattices and engineered linkages for the efficient and clean production of hydrogen peroxide…

The NUS researchers demonstrated the emergence of robust spin-polarisation in graphene on a ferrimagnetic insulating oxide Tm3Fe5O12 (TmIG) with large spin-splitting energy of up to hundreds of meV. The observed spin polarisation in graphene with large and tunable spin-splitting energy holds great promise for promises the field of 2D spintronics for low-power electronics.

By National University of Singapore, Yong Loo Lin School of Medicine November 29, 2023 A long-term study in Singapore shows that adults who consume more caffeine through coffee or tea in midlife have a lower likelihood of physical frailty in old age, indicating the potential health benefits of these beverages. Consumption of coffee and tea during middle age may be linked to a lower chance of experiencing physical frailty in later life. A study in Singapore has revealed that adults who consume more caffeine through…
