Abstract Artificially improving traits of cultivated alfalfa ( Medicago sativa L.), one the most important forage crops, is challenging due to lack a reference genome and an efficient editing protocol, which mainly result from its autotetraploidy self-incompatibility. Here, we generate allele-aware chromosome-level assembly for consisting 32 allelic chromosomes by integrating high-fidelity single-molecule sequencing Hi-C data. We further establish CRISPR/Cas9-based protocol on basis this...
The year 2019 marks the 10th anniversary of first report ultrafast fiber laser mode-locked by graphene. This result has had an important impact on optics and continues to offer new horizons. Herein, we mainly review linear nonlinear photonic properties two-dimensional (2D) materials, as well their applications in efficient passive mode-locking devices lasers. Initial works significant progress this field, insights challenges 2D materials for lasers, are reviewed analyzed.
Orchidaceae is the second largest family of flowering plants, which highly valued for its ornamental purposes and medicinal uses. Dendrobium officinale a special orchid species that can grow without seed vernalization. Because whole-genome sequence D. publicly available, this poised to become convenient research model evolutionary, developmental, genetic studies Orchidaceae. Despite these advantages, methods manipulation are poorly developed in officinale. In study, based on previously...
Rice yield is an important and complex agronomic trait controlled by multiple genes. In recent decades, dozens of yield-associated genes in rice have been cloned, many which can increase production the form loss or degeneration function. However, mutations occurring randomly under natural conditions provided very limited genetic resources for increases. this study, potentially yield-increasing alleles two closely associated with were edited artificially. The recently developed CRISPR/Cas9...
Magnetotactic bacteria are ubiquitous microorganisms in nature that synthesize intracellular magnetic nanoparticles called magnetosomes a gene-controlled way and arrange them chains. From vitro to vivo, we demonstrate the intact body of Magnetospirillum magneticum AMB-1 has potential as natural hyperthermia material for cancer therapy. Compared chains individual magnetosomes, entire cell exhibits superior heating capability under an alternating field. When incubating with tumor cells, cells...
Magnetotactic bacteria (MTB) represent a model system for understanding biomineralization and are also studied intensively in biogeomagnetic paleomagnetic research. However, many uncultured MTB strains have not been identified phylogenetically or investigated structurally at the single-cell level, which limits comprehensive of diversity their role biomineralization. We novel strain, WYHR-1, from freshwater lake using coupled fluorescence scanning electron microscopy approach scale. Our...
In general, there is a fundamental trade-off between the operational bandwidth and attainable absorption. So, obtaining broadband wave absorption of low reference standard such as 90% not very difficult. However, when trying to obtain higher 99%, will drop dramatically. Here, we demonstrate that near-perfect over 99% with 60% relative can be obtained utilizing single-layered nonstructured graphene loaded periodical dielectric wires. The mechanism originates from coupling Mie resonances in...
Typical morphology substrates can improve the efficiency of surface-enhanced Raman scattering; need for SERS controlled requires an extensive study. In this paper, one-dimensional ZnS:Al nanostructures with width approximately 300 nm and length tens um, micro-scale structures several um were synthesized via thermal evaporation on Au-coated silicon used to study their size effects scattering photoluminescent spectra. The photoluminescence spectra reveal strongest green emission at a 5 at% Al...
Abstract All‐optical modulation plays a key role in next‐generation optical processing and has attracted enormous attention worldwide. With extraordinary optoelectronic characteristics friendly integration compatibility with various nanostructures, graphene shows great potential for ultrafast energy‐efficient all‐optical modulation. Here, high‐efficiency on‐chip is experimentally demonstrated based on ultra‐thin silicon/graphene hybrid waveguides, which are...
We studied the temperature dependence of light yield linear alkyl benzene (LAB)-based and mesitylene-based liquid scintillators. The increases by 23% for both scintillators when is lowered from 26 °C to −40 °C, correcting response photomultiplier tube. measurements help understand energy scintillator detectors. Especially, next generation reactor neutrino experiments mass hierarchy, such as Jiangmen Underground Neutrino Observatory (JUNO), require very high resolution. As no apparent...
Liquid scintillator (LS) will be adopted as the detector material in JUNO (Jiangmen Underground Neutrino Observatory). The energy resolution requirement of is 3%, which has never previously been reached. To achieve this resolution, light yield liquid an important factor. PPO (the fluor) and bis-MSB wavelength shifter) are two main materials dissolved LAB. study influence these on transmission scintillation photons LS, 25 12 cm-long quartz vessels were used a experiment. LS samples with...
Types 316 and 304 stainless steel are two candidates for the storage vessels piping systems of LAB-based liquid scintillator (LS) in JUNO experiment. LS aging experiments carried out at temperatures 40 °C 25 °C. After 192 days °C, attenuation length was reduced by 6% a glass container, 12% type tank, 10% tank. At tanks, after 307 days. The light yield absorption spectrum were practically same as that unaged sample. concentration element Fe did not show clear change. Type can be used...
Conventional orthogonal machining is an effective severe plastic deformation (SPD) method to fabricate ultrafine-grained (UFG) materials. However, UFG materials produced by room temperature-free (RT-FM) are prone dynamic recovery, which decreases the mechanical properties of In this study, cryogenic technique was implemented chips that have abundant microstructure. Solution-treated Al-7075 bulk has been processed in temperature (CT) and (RT) with various parameters, respectively. The...
