Freshwater scarcity is a globally significant challenge threatening the development of human society. Sorption-based atmospheric water harvesting offers an appealing way to solve this challenge by extracting clean water from the air. However, the weak ability of sorbents to capture water from dry air and the

1. Introduction While innovation is vital to ensure a country''s long-term economic growth and competitive advantage (Solow, 1957), motivating and nurturing innovation is very difficult.As Holmstrom (1989) points out, the whole innovation process is not only long, idiosyncratic, and unpredictable, but also involves a very high probability of failure.

Sn–Pb mixed perovskites with bandgaps in the range of 1.1–1.4 eV are ideal candidates for single-junction solar cells to approach the Shockley–Queisser limit. However, the efficiency and stability of Sn–Pb mixed-perovskite solar cells (PSCs) still lag far behind ...
In order to investigate the interaction between the carbazole and the perovskite, we conducted Fourier transform infrared (FTIR) spectroscopy. In Figure 2 A, the absorption peak of the pure carbazole sample at around 3,416, 1,597, and 1,449 cm −1 could be attributed to N–H stretching, N–H related bending, and C–N stretching frequencies, …
The advent of intelligent image-activated cell sorting (iIACS) has enabled high-throughput intelligent image-based sorting of single live cells from heterogeneous populations. iIACS is an on-chip microfluidic technology that builds on a seamless integration of a high-throughput fluorescence microscope, cell

Device lifetime and power conversion efficiency (PCE) are the key factors determining the final cost of the electricity that solar cells generate. The certified PCE of perovskite solar cells (PSCs) has rapidly reached 23.7% over the past few years (1–9), which is on par with that of polycrystalline silicon and Cu(In,Ga)Se 2 solar cells, but poor device stability …
