Abstract The Asteraceae (daisy family) is one of the largest families plants. genetic basis for its high biodiversity and excellent adaptability has not been elucidated. Here, we compare genomes 29 terrestrial plant species, including two de novo chromosome-scale genome assemblies stem lettuce, a member Asteraceae, Scaevola taccada , Goodeniaceae that closest outgroups Asteraceae. We show originated ~80 million years ago experienced repeated paleopolyploidization. PII, universal regulator...
We studied the electronic transport properties of metal nanoparticle arrays, particularly focused on Coulomb charging energy. By comparison, we confirmed that it is more reasonable to estimate energy using activation from temperature-dependent zero-voltage conductance. Based this, systematically and comprehensively investigated parameters could be used tune in arrays. found four parameters, including particle core size, inter-particle distance, nearest neighboring number, dielectric constant...
Intergranular cracks originating from volume change during charging/discharging have been observed in many cathodes of lithium ion batteries, which are considered to be closely related capacity fading. Using first principles calculations systematically study the behavior representative intercalation delithiation, we elucidated how Coulombic interaction and bond length affect behaviors with different structural flexibility. Jahn-Teller distortions, dopants, ionic radii, site-exchanges,...
Charge transport properties in close-packed nanoparticle arrays with thickness crossing over from two dimensions to three have been studied. The dimensionality transition of was realized by continually printing spatially well-defined monolayers on top the device situ. evolution charge depending has investigated both Efros-Shaklovskii variable-range-hopping (ES-VRH) (low temperature) regime and sequential hopping (SH) (medium regime. We find that energy barriers decrease when increases...
Chiral nanomaterials offer intriguing possibilities for novel electronic and chemical applications. Here, we report the discovery of an enantiomer-selective magnetoresistance effect in chiral gold nanocrystals. Based on precise control nanocrystal morphology using amino acid-directed synthesis, demonstrate that external magnetic field can dramatically modulate resistance enantiomer-specific manner. For a given enantiomer, one direction alters by over order magnitude, while opposite leaves it...
By studying the formation and dynamics of a small polaron in doped FePO 4 , it is found that doping S at P site changes motion mode polaron, thus increasing intrinsic electronic conductivity .
In this paper, wafer bonding using Parylene as the adhesive layer is investigated. The experiments are carried out under various conditions in two approaches: Parylene-to-Parylene and Parylene-to-Silicon. By heating at 230°C applying a force vacuum environment, both Parylene-Parylene Parylene-Silicon successfully bonded. quality characterized by joint area strength. results show that there no significant difference on qualities between approaches. Process parameters, such film thickness,...
Abstract We use the measurements from Magnetospheric MultiScale spacecraft to study intermittency of magnetic field ( B -field) and electric E fluctuations ion scales (around 1 Hz in frame) sub-electron (about 1000Hz) magnetosheath. For first time, this shows remarkable differences intermittent properties between these two fields: (1) The multiorder structure functions -field trace are more flattened as compared those fluctuations. (2) flatness increases monotonically with decreasing...
