Aim To establish a gene co-expression network for identifying principal modules and hub genes that are associated with drought resistance mechanisms, analyzing their exploring candidate genes. Methods findings 42 data sets including PRJNA380841 PRJNA369686 were used to construct the through weighted analysis (WGCNA). A total of 1,896,897,901 (284.30 Gb) clean reads 35,021 differentially expressed (DEGs) obtained from samples. Functional enrichment indicated photosynthesis, DNA replication,...
Conformational arrangements in polymers on surfaces determine the overall shape as well potential properties. It is generally believed that conformational diversity leads to uncontrollable or disordered structures on-surface synthesis. However, this study, we obtain two well-ordered self-assembled covalently linked wavy chains with site-selective switching via Ullmann reaction of 1,2-bis(3-bromophenyl)ethane multiple conformations Ag(111). Two kinds exhibit distinct arrangements, where chain...
Metal–organic frameworks (MOFs) can provide atomically dispersed metal active coordination sites (M–NX, M–SX, and M–OX) for electrocatalytic reactions. Among them, MOFs with motif M–NX or analogues are expected to be promising electrode materials oxygen evolution reaction (OER). Contrary bulk MOFs, two-dimensional (2D) usually have high surface areas, fully exposed sites, specific electrical properties. Herein, we constructed 2D Ni3(hexaiminotriphenylene)2 [Ni3(HITP)2] films on the by...
Autler-Townes (AT) splitting is observed in ultracold cesium Rydberg gases. Frequency and power of the laser field coupling $6S$${}_{1/2}$ $6P$${}_{3/2}$ levels are tuned to influence population redistribution $nS$ excited by another light. The profile AT spectroscopy measured experimentally compared with theoretical simulation considering estimated large dephasing rates caused interaction between atoms, which demonstrates that spectra strongly dependent on atoms. Rabi frequency transition...
Three types of well-ordered covalent two-dimensional tilings including triangular, rhombille and semi-regular Archimedean were successfully constructed via on-surface Schiff base reaction. Among them, the organic framework (COF) from a C6 symmetry monomer C3 is first reported COF with kgd (rhombille tiling) topology.
We present a laser frequency locking to Rydberg transition with electromagnetically induced transparency (EIT) spectra in room-temperature cesium vapor cell. Cesium levels 6S1/2, 6P3/2, and the nD5/2 state, compose cascade three-level system, where coupling drives transition, probe detects EIT signal. The error signal, obtained by demodulating is used lock transition. fluctuation, ∼0.7 MHz, after on, minimum Allan variance be 8.9 × 10−11. This kind of method can stabilize excited
This paper is concerned with young people's perceptions and reported use of the two language varieties that co-exist in urban centre Guangzhou southern China, Putonghua (P) Cantonese (C). P a typical H-variety, promoted by government used as lingua franca throughout China; C local L-variety but it also has some prestige all domains. The focus our questionnaire study was twofold: to analyse possible gender differences use, compare results from P-speaking newcomers, who have moved other parts...
We study the effects of Rydberg-atom interactions on Autler-Townes (AT) spectra in a dense gas ultracold cesium atoms. The $6{S}_{1/2}$ and $6{P}_{3/2}$ levels are strongly coupled (Rabi frequency ${\ensuremath{\Omega}}_{c})$, resultant AT probed via excitation into Rydberg level. Van der Waals between atoms probe level give rise to dephasing rate $({\ensuremath{\gamma}}_{3})$. interaction-induced is found cause characteristic changes spectra, including reduction or elimination splitting, an...
We present a method to control collisions between ultracold neutral atoms in the electronic ground state and trapped ions. During collision, atom is resonantly excited by laser low-field-seeking Rydberg state, which repelled ion. As reflected from ion, it de-excited back into its level. The efficiency of shielding analyzed as function frequency power, initial atom-ion collision energy, angle. suitability several levels Na Rb for discussed. Useful applications include suppression unwanted...
The authors observe spin-orbit interaction in electron-neutral scattering, which has been elusive so far. This result is obtained by using ultralong-range Rydberg molecules as a micro laboratory for low-energy scattering experiments. gives rise to fine structure multiplet the molecular term spectrum resolved via photoassociation spectroscopy.
The on-surface synthesis of single-layered covalent organic frameworks (sCOFs) has been investigated by employing a 3-fold symmetric monomer 1 carrying aldehyde groups and the ditopic diamine building block 2 on highly oriented pyrolytic graphite surface. self-assembly molecule is persistently observed at stoichiometric ratio reactive groups. growth sCOF network observed, however, only excess monomers. By investigating process network, role excessive monomers can be understood two aspects....
The $l$-mixing effect and state-transfer induced by an external electric field pulse in ultracold Rydberg gases are observed with cesium atoms excited to $\mathit{nS}$ states, measured a state selective ionization technique. High-$l$ states populated from the initially due non-adiabatic transitions through avoided crossings that formed between ($n\ensuremath{-}4$) manifold. population of product is investigated as function parameters. coherent property transfer demonstrated using 2-pulse...
We report on the two-dimensional self-assembly of C 2v-symmetric [1,1':3',1''-terphenyl]-3,3'',5,5''-tetracarboxylic acid (TPTA) at solid/liquid interface by using scanning tunneling microscopy (STM). Two kinds different structure, i.e. a close-packed and porous rosette are formed TPTA molecules through intermolecular hydrogen bonds. When adding coronene (COR) as guest into assembly, structural transformation from densely packed row structure to network is observed. It was found that two...
