  摘要：Catalytic enantioselective methods that are generally applicable to a broad range of substrates are rare. We report a strategy for the oxidative desymmetrization of meso-diols predicated on a nontraditional catalyst optimization protocol by using a panel of screening substrates rather than a singular model substrate. Critical to this approach was rational modulation of a peptide sequence in the catalyst incorporating a distinct aminoxyl-based active residue. A general catalyst emerged, providi...

  摘要：In an otherwise excellent analysis of fair regional shares of global mitigation investments, Pachauri et al. (Policy Forum, 9 December 2022, p. 1057) dramatically overestimate developing countries' 'capability' to invest by estimating GDP using purchasing power parity exchange rates. Since internationally sourced investment goods must be paid for at market exchange rates, capability-based interregional finance flows should be vastly larger.

  摘要：Quantum entanglement is a key resource in currently developed quantum technologies. Sharing would enable new functionalities, but this has been hindered by an energy scale mismatch of entanglement between microwave and optical fields in a millikelvin environment. Using an optically pulsed superconducting electro-optical device, we show entanglement between propagating microwave and optical fields in the continuous variable domain. This achievement not only paves the way for entanglement betwee...
