Abstract Fully internal and motional state controlled individually manipulable polar molecules are desirable for many quantum science applications leveraging the rich space intrinsic interactions of molecules. While prior efforts at assembling from their constituent atoms trapped in optical tweezers achieved such a goal exactly one molecule (Zhang J T et al 2020 Phys. Rev. Lett. 124 253401; Cairncross W B 2021 126 123402; He X Science 370 331–5), here we extend technique to an array five...
The enantioselective cyanoalkylation of styrenes by a cooperative photoredox and copper catalysis system has been established, providing straightforward access to structurally diverse enantioenriched alkyl nitriles in good yields with excellent enantioselectivities under mild conditions via deoxygenation alkoxyl radicals organophosphorus compounds(III). In addition, the reaction features wide substrate scope functional group tolerance, resultant could be easily converted into series chiral...

We measure the mass, gap, and magnetic moment of a magnon in ferromagnetic $F=1$ spinor Bose-Einstein condensate $^{87}$Rb. find an unusually heavy mass $1.038(2)_\mathrm{stat}(8)_\mathrm{sys}$ times atomic as determined by interfering standing running coherent waves within dense trapped condensed gas. This measurement is shifted significantly from theoretical estimates. The energy gap $h\times 2.5(1)_\mathrm{stat}(2)_\mathrm{sys}\;\mathrm{Hz}$ effective...
We demonstrate quantum coherent control of single electronic spins in a nitron-vacancy center diamond by exploiting and implementing the general concept Landau-Zener-Stückelberg interferometry at room temperature. The manipulates an effective two-level system which are coupled to nearby N14 nuclear spin as well bath diamond. With microwave field energy gap between two levels AC time-dependent driving interferometry, interference pattern can be generated controlled controlling number...
The separation of para-halotoluene (PHT) is crucial in the chemical industry. However, due to similar physical properties those halotoluene isomers, industrial can be time-consuming and energy-intensive. Herein, we present an energy-efficient method for adsorptive PHT, such as para-chlorotoluene para-bromotoluene, from their trinary isomer mixture using a trianglimine (TI) macrocycle. selectivity dominated by C–H···π, ···π, C–H···Cl interactions between TI macrocycle captured guest molecule....
A mixture of TiF3-doped NaH/Al was directly used as the starting material, and hydrogenated singly in order to study chemical state role Ti species hydrogenation. X-ray absorption spectroscopy shows that Ti3+ essentially reduced Ti0 formed Ti−Al clusters during doping, i.e. ball-milling process. The local environment around atoms became homogeneous ordered after hydrogenation at 100−140 °C. are believed be catalyzing agent for dissociation hydrogen molecule subsequent formation hydride.
We observe the quasicondensation of magnon excitations within an F=1 ^{87}Rb spinor Bose-Einstein condensed gas. Magnons are pumped into a ferromagnetically ordered gas, allowed to equilibrate nondegenerate distribution, and then cooled evaporatively at near-constant net longitudinal magnetization, whereupon they condense. The critical number, spatial momentum distribution indicate that magnons condense in potential is uniform volume ferromagnetic condensate. macroscopic transverse...
The thermal stability and hydrogen desorption kinetics for MgH2 Mg2NiH4 before after doping with TiF3 or Ti(OBun)4 were studied by X-ray diffraction, differential analysis, thermogravimetry, Fourier transform infrared spectroscopy, absorption spectroscopy techniques. Unlike the previous work, mixture of hydrides dopants was gently ground a short time to avoid undesirable side effects accompanied an intensive prolonged grinding. It is shown that onset temperature release around 420 °C blank...
Transition-metal chalcogenides (TMCs) show great potential as highly efficient and cost-effective electrocatalysts for oxygen evolution reaction (OER). Yet the electrochemical conversion into oxides/hydroxides remains poorly understood. In this work, we develop a built-in, electric-field-induced surface reconstruction strategy ultra-fast self-activation of transition metal sites in self-supporting CoS2/CuS heterostructures. The activated grown on carbon cloth with oxygenated species displays...
We demonstrate a 90 cm launch of Cs atoms guided by one-dimensional (1D) optical lattice. The 1064 nm wavelength lattice is made in 2 m long buildup cavity and provides transverse guide depth up to 125 microK. Before they reach the top their trajectory, are stopped cooled molasses, becoming trapped 1D can be loaded with multiple launches, filling sites that extend over 5 cm. trap far from all magnetic sources will used for precision measurement electron electric-dipole moment.
The presence of missing value in time series increase the difficulty data analysis. traditional interpolation method is mainly aim at simple numeric missing, which without considering correlation among points actual series, so it easy to distort hidden relationship points. Therefore, based on Snurbs (series-Non-Uniform Rational B-Spline) method, we present a further combines window adjustment correlation. new algorithm was applied two real world hydrological represent periodic and aperiodic...
We observe spin transfer within a non-degenerate heteronuclear spinor atomic gas comprised of small $^7$Li population admixed with $^{87}$Rb bath, both elements in their $F=1$ hyperfine manifolds and at temperatures 10's $\mu$K. Prepared non-equilibrium initial state, the distribution evolves through incoherent spin-changing collisions toward steady-state distribution. identify measure cross-sections all three types spin-dependent collisions, namely spin-exchange, spin-mixing,...
We measure the interspecies interaction strength between $^7$Li and $^{87}$Rb atoms through cross-dimensional relaxation of two-element gas mixtures trapped in a spherical quadrupole magnetic trap. record an initial momentum-space anisotropy lithium when co-trapped with rubidium atoms, both species $|F=1, m_F = -1\rangle$ hyperfine state. Our measurements are calibrated by observing $^{87}$Rb-only gas. Through Monte Carlo simulations, we compare observed to that expected given theoretically...
