Two-thirds of the electricity in the United States is generated from fossil fuel via combustion-powered steam turbines. To get to the high temperatures needed for high efficiency, steam must first be vaporized from liquid water. The steam is further heated, expanded through the turbine, and condensed to water on the other side. In this process, called the Rankine cycle, the vaporization step is a phase change that requires a large heat input but delivers no increase in temperature (or efficiency). Advanced steam turbines try to avoid the phase change by going to supercritical conditions, but attempts to exhaust heat at low temperatures push parts of this cycle to operate just above water's critical point (374°C and 218 atm). Near this point, steam's heat capacity increases sharply, so up to 36% of total heat input still goes to a low-temperature, vaporizer-like process (see the figure). By switching from steam to supercritical CO2 (scCO2) and running a Brayton cycle (the same cycle run by natural gas turbines), the ?vaporizer? step can be avoided, providing an opportunity to replace subcritical steam plants with a cycle that could be up to 30% more efficient. These gains are expected to persist in the smaller turbine sizes suited for harvesting solar thermal energy.
Natural gas must be purified before it can be transported. The preparation process also includes a drying step to remove water. Microporous adsorbents such as zeolites are used for this purpose, but they often need to be heated to temperatures up to 250°C to remove the water so that they can be reused. Cadiau et al. describe a fluorinated metal-organic framework containing nickel metal centers that can remove water from gas streams but that can be regenerated by heating to only 105°C.

A cell?s response to changes in its extracellular or intracellular environment (the path between signal and output) involves complex molecular networks. These networks are temporally dynamic, requiring investigators to consider multiple time points when analyzing pathway activity. Using single-cell imaging, Stewart-Ornstein and Lahav showed not only that DNA damage dynamically induced the tumor suppressor protein p53, which regulates cell cycle arrest and apoptosis, but also that those dynamics varied between cell lines, even of the same tissue type. The findings provide insight into the p53-mediated DNA damage response in multiple cell types. Because many other signaling pathways likely demonstrate this high degree of variability, the study also reveals that making generalized assumptions about cell signaling behavior based on a single cell line, or even one line for each tissue, is prone to error.
Although perovskite solar cells (PSCs) can have power conversion efficiencies exceeding 20%, they can have limited stability under ultraviolet irradiation. This is in part because the mesoporous TiO2 used as an electron-transporting layer can photocatalyze unwanted reactions in the perovskite layer. Shin et al. report a low-temperature colloidal method for depositing La-doped BaSnO3 films as a replacement for TiO2 to reduce such ultraviolet-induced damage. Solar cells retained over 90% of their initial performance after 1000 hours of full sun illumination.

The efficiency of organic light-emitting diodes (OLEDs) is fundamentally governed by the ratio of emissive singlet to dark triplet excitons that are formed from spin-polarized electron and hole currents within the material. Typically, this has set an upper limit of 25% internal
If charge carriers in solar cells can be harvested before they cool on their way to equilibrium, then the Shockley-Queisser limit of 33% for solar cell efficiency can potentially be beaten. Long carrier lifetimes (?100 ps) have been reported for hybrid organic-inorganic metal halide perovskites. Guo et al. imaged charge transport in CH3NH3PbI3 thin films with transient absorption microscopy. Hot carriers could travel up to 600 nm, which suggests that devices that harvest hot carriers may be feasible.

This Artificial Intelligence story is changing the way enterprises understand AI in the modern data-evolved world.
Low-temperature processing of planar organic-inorganic perovskite solar cells made through solution processing would allow for simpler manufacturing and the use of flexible substrates. However, materials currently in use form interfaces with charge carrier trap states that limit performance. Tan et al. used chlorine-capped TiO2 colloidal nanocrystal films as an electron-selective layer, which limited interface recombination in solution-processed solar cells. Such cells achieved certified efficiencies of 19.5% for active areas of 1.1 cm2.

Amines, molecules containing carbon-nitrogen (C?N) bonds, are among the most common and biologically important molecules in organic chemistry; 84% of small-molecule pharmaceuticals contain at least one C?N bond ( 1 ). Hydroamination, the direct addition of an N?H bond across a carbon-carbon double or triple bond, represents an ideal approach for the synthesis of amines ( 2 ). Despite extensive research over the past several decades, the efficient and direct intermolecular hydroamination of unactivated alkenes with anti -Markovnikov regio-selectivity (see the top panel of the figure) has remained a challenge. On page 727 of this issue, Musacchio et al. ( 3 ) report a photochemical strategy for creating reactive ammonium radical cations (ARCs) that can form these less stable isomers.
