Organic solar cells (OSCs) have been dominated by donor: acceptor blends based on
fullerene acceptors for over two decades. This situation has changed recently, with non …

Metal halide perovskites have shown promising optoelectronic properties suitable for light-
emitting applications. The development of perovskite light-emitting diodes (PeLEDs) has …

Globally, human immunodeficiency virus–type 1 (HIV-1) is extraordinarily variable, and this
diversity poses a major obstacle to AIDS vaccine development. Currently, candidate …

Molecular design of non-fullerene acceptors is of vital importance for high-efficiency organic
solar cells. The branched alkyl chain modification is often regarded as a counter-intuitive …

The human AIDS viruses human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2)
