The chemical origin of temperature-dependent lithium-ion concerted diffusion in sulfide solid electrolyte Li_(10)GeP_(2)S_(12)

Solid-state batteries have received increasing attention in scientific and industrial communities,which benefits from the intrinsically safe solid electrolytes(SEs).Although much effort has been devoted to designing SEs with high ionic conductivities,it is extremely difficult to fully understand the ionic diffusion mechanisms in SEs through conventional experimental and theoretical methods.Herein,the temperature-dependent concerted diffusion mechanism of ions in SEs is explored through machinelearning molecular dynamics,taking Li_(10)GeP_(2)S_(12) as a prototype.Weaker diffusion anisotropy,more disordered Li distributions,and shorter residence time are observed at a higher temperature.Arrhenius-type temperature dependence is maintained within a wide temperature range,which is attributed to the linear temperature dependence of jump frequencies of various concerted diffusion modes.These results provide a theoretical framework to understand the ionic diffusion mechanisms in SEs and deepen the understanding of the chemical origin of temperature-dependent concerted diffusions in SEs.

CONCERTED H-BONDING TEMPLATE SYNTHESIS OF AN ORDERED LADDER POLYSILSESQUIOXANE

A novel soluble regular ladder poly（benzoyl-3-aminopropyl） silsesquioxane （LPBAS） was facilely prepared under effective assistance of concerted H-bonding self-assembly of amido groups of side chains and silanol groups, respectively, of a new template monomer [1,3-bis（benzoyl-3-aminopropyl）-1,1,3,3-tetraethoxydisiloxane] （M）. The ordered ladder structure of LPBAS is manifested in： （1） the presence of two Bragg peaks representing the ladder width （d） and ladder thickness （t） in X-ray diffraction （XRD） pattern; （2） narrow base-line width （w = 6） of resonance absorption for -CH2SiO3/2 moiety in 29Si-NMR and （3） high glass transition temperature Tg = 1 12℃ in differential scanning calorimetry （DSC） analysis.

MOLECULAR POLARIZATION INDUCTION IN CONCERTED MECHANISM OF ALKOXY MIGRATION

The rearrangement of α-substituted phenyl-α, α′-dimethoxypropanones (R1) was recently proved to he an [1, 3] siqmatropic migration of methoxy group by study of LFER, solvent effect, crossover experiment, and by other means. The rearrangement catalysed by trace of totuenesulfonic acid gave a negligible value of the Hammett reaction constant. Further experimental results show that the electronic effect of substituent on the aromatic ring for the rearrangement in neutral medium is much greater (Table 1). We propose sigmatropic migration

Common Goal,Concerted Efforts

THRONGS of people were overwhelmed by tears and cheers on December 12, 2015 as French Foreign Minister Laurent Fabius, president of the Paris climate change conference, struck a green gavel. It signaled the conclusion of a marathon 13- day negotiation between delegates representing nearly 200 different countries and regions, who had gathered in Paris. The representatives at the 2015 United Nations Climate Change Conference made a deal that will go down in history as a rare moment of worldwide cooperation in the face of a monumental challenge, But as fellow negotiators hugged each other in celebration, grave concerns lurked in the recesses of their minds - this was just the beginning of a war against climate change that is expected to last for generations.

Solar cells based on doubly concerted companion dyes with the efficiencies modulated by inserting an ethynyl group at different positions

To develop efficient sensitizers for dye-sensitized solar cells(DSSCs),we recently reported doubly concerted companion(DCC)dye XW83 with a wrapped porphyrin sub-dye unit linked to an organic sub-dye unit through a flexible chain,which exhibits panchromatic absorption and excellent anti-aggregation ability.To further improve the absorption,we herein report XW87 and XW88 by inserting an ethynyl group into the organic sub-dye unit of XW83 near the donor and acceptor,respectively.For the corresponding organic dyes Z3 and Z4,the introduced ethynyl group improves their absorption,but induces aggravated charge recombination,leading to lowered power conversion efficiencies(PCEs).Similar to the organic dyes,the introduced ethynyl group improves the absorption of DCC dyes XW87 and XW88 as well.In addition,the ethynyl group near the acceptor of the organic sub-dye unit can be well protected by the long wrapping chains from the porphyrin unit.As a result,XW88 affords the highest JSC(21.84 mA/cm^(2)),V_(OC)(782 mV)and PCE(12.2%)among the DCC dyes.These results provide an effective method for developing efficient DSSC dyes by inserting an ethynyl group at a suitable position of a DCC dye.

BiOBr/COF S-scheme photocatalyst for H_(2)O_(2) production via concerted two-electron pathway

Constructing step-scheme(S-scheme)heterojunctions has become a popular strategy for efficient pho-tocatalytic H_(2)O_(2) generation.Herein,we in situ grew BiOBr nanosheets(NSs)on a Schiff-base covalent organic framework(COF)with largeπ-conjugated structures to prepare S-scheme BiOBr/COF photocat-alysts for H_(2)O_(2) synthesis.The highest photocatalytic H_(2)O_(2) production performance of the composite sample constituting the S-scheme heterojunction is 3749μmol g−1 h−1,which was 1.85 and 27 times the rates of COF and BiOBr,respectively.The construction of S-scheme heterojunction contributed to ef-ficient carrier transfer and separation in space and enhanced redox power.Moreover,the lying-down O_(2)-adsorption configuration on the COF surface favors the concerted two-electron O_(2) reduction process,which greatly reduced the reduction potential requirement for O_(2)-to-H_(2)O_(2) conversion.The synergy be-tween the S-scheme heterojunction and the unique O_(2)-COF interaction boosted photocatalytic H_(2)O_(2) pro-duction activity.

Can"Concerted"Macroprudential Policies Mitigate Cross-border Contagion of Financial Risks?Evidence from China and Its Financially Connected Economies

We construct a connected network between China and the economies that are financially linked to it,based on the network topology of variance decompositions,and measure the cross-border contagion of financial risks among these economies.We then examine whether the concerted use of macroprudential policies mitigates the cross-border contagion of financial risks.The empirical results show that the tightening of macroprudential policies,especially counter-cyclical capital buffers and limits on credit growth,in economies with net spillover risk(e.g.the US and China).can reduce the cross-border spillover of domestic financial risks to other economies.The concerted use of macroprudential policies can contribute to global financial stability.However,the tightening of"capital"macroprudential policy tools will increase domestic cross-border absorption of financial risks.Hence,macroprudential regulation of cross-border capital flows must be strengthened.

The Principle of Concerted Evolution Between Interacting Proteins—Darwinian Selection at Molecular Level

The neutral theory raised by Motoo Kimura in 1968 asserts that 'the great majority of evolutionary changes at the molecular level, as revealed by comparative studies of protein and DNA sequences. are caused not by Darwinian selection but by random drift of selectively neutral or nearly neutral mutants'.

Principle of Concerted Evolution of Cytokine-receptor and Verification of Its Corollary

Cytokines mediate their pleiotropic actions by binding to and activating theircell-surface receptors.So far,people have learned much about their biological characteristics,biochemical profile,and the interaction or modulation between cytokines and theirreceptors as well.However,people have no idea about what relationship of cytokines withtheir receptors in phylogeny exists.

Efficient dye-sensitized solar cells based on concerted companion dyes:Systematic optimization of thiophene units in the organic dye components

To develop efficient concerted companion(CC)dyes for fabricating high-performance DSSCs,three organic dyes XL1-XL3 have been designed by varying the position and number of theβ-hexylthiophene(HT)bridges,and these organic dye units are covalently linked with our previously reported porphyrin dye XW10 to construct the corresponding CC dyes XW74-XW76.Among the organic dyes,XL3 contains twoβ-hexylthiophene units at both the donor and acceptor parts and thus possesses stronger light-harvesting capability in the green light region.Because of the most complementary absorption between XL3 and XW10 as well as the excellent photovoltaic behavior of the individual XL3 dye,the corresponding CC dye XW76 affords the best PCE(10.78%)among all the CC dyes.Upon coadsorption with CDCA,XW76 affords a highest PCE of 11.35%,which outperforms the previous cosensitization system of XW10+WS-5.This work provides an approach for developing efficient DSSCs based on CC dyes composed of an organic dye unit with suitableπspacers inserted at appropriate positions.
