Spontaneous Chiral Resolution of a MnIII Spin Crossover Complex …
Splet11. mar. 2024 · A novel helix hydrogel with a G-quartet structure was synthesized from guanosine (Gua) and its derivative 5′-guanosine monophosphate (5′-GMP) under a molecular crowding environment. The chirality of the hydrogel is adjusted by controlling the gelling speed. The chiral hydrogel can induce an achiral dye Thiof SpletThe development of switchable chemo-, regio-, or diastereodivergent reactions, in which two or more structurally and stereogenically different types of chiral products could be produced efficiently from an identical set of starting materials under readily tunable catalytic conditions, is one of the ultimate goals in asymmetric catalysis. cycle china

Splet10. apr. 2024 · Non-centrosymmetric spin switchable systems are of interest for their prospective applications as magnetically active non-linear optical materials and in multiferroic devices. Chiral resolution of simple spin crossover chelates complexes into the Δ and Λ forms offers a facile route to homochiral magnetic switches, which could be … Splet13. okt. 2024 · Switchable chirality has never before been observed and may well find its application in future technology. It is clear that this unusual behavior is directly linked to … To obtain the tensile strain applied to the sample, we first need to estimate the total displacement of the samples and substrates used due to different thermal contraction coefficients. On cooling from 300 K to 4 K, the integrated thermal contraction coefficients of SiNx (εSiN) and Si (εSi) were 0.0342% … Prikaži več CsV3Sb5 crystallizes in the P6/mmm space group, which features a layered structure of kagome planes formed by the V atoms (Extended Data Fig. 1). The single crystals were grown … Prikaži več At low temperature, angle-dependent magnetoresistivity displays a strong peak when the magnetic field direction rotates across the kagome plane (Extended Data Fig. 2). With … Prikaži več Joule heating is a natural extrinsic origin of higher harmonic voltage generation43,44. Applying an a.c. electric current, Iω, must result in an oscillating temperature with a frequency of 2ω. Therefore if the … Prikaži več Second-harmonic voltage generation due to eMChA is expected to display a quadratic current dependence. Here we present the I–V characteristics of both first- and second-harmonic voltages measured with a 7 … Prikaži več cycle choreography
