Two new functional polyacetylenes bearing different azobenzene group, -{ HC=C[azo-N （CH3）CH2CH2OH] } n-, [poly（EHAB）; azo = 4,4＇-azobenzene] and - { HC=C[azo-N（CH3）CH2CH2O COC3H7]},-, [poly（EEAB）]} were prepared by [Rh（nbd）Cl]2-Et3N catalysts. Poly（EHAB） has poor solubility while poly（EEAB） can be dissolved in common solvent. The polymers were characterized by FHR, ^1H NMR, UV and GPC. The nonlinear optical property of the soluble poly（EEAB） was investigated with 8 ns width pulse at 532 nm by Z-scan technique. The results show that poly（EEAB） is endowed with the larger third-order nonlinear optical property.

Two novel polyacetylenes bearing nonlinear optical chromophoric group poly（3-（4-[4-（n-butyloxy） phenylazophenyl]carbonyl）oxy-1-propyne）（poly（1a）） and poly（3-（4-[4-（n-heptyloxy）phenylazophenyl]carbonyl）-oxy-l- propyne）（poly（lb）） were synthesized with [Rh（nbd）Cl]2-EtaN as catalysts. These polyacetylenes are soluble by using an alkyl spacer and an alkyloxyl group as a substituent. They were characterized by FTIR, NMR, GPC and UV-Vis and their optical limiting and nonlinear optical properties were investigated using 8 ns pulse at 532 nm wavenumber. The results show that these soluble functional polyacetylenes possess optical limiting properties and large nonlinear optical properties and poly（1b） possesses better optical limiting and nonlinear optical properties than poly（ 1 a）.

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.

We investigate the interannual variability of the South Asian summer monsoon（SASM） circulation, which has experienced a significant interdecadal change since 2000. This change is primarily influenced by sea surface temperatures（SSTs）in the tropical Pacific and North Atlantic oceans. During the pre-2000 period examined in this study（1979-99）, the SASM is negatively correlated with eastern Pacific SSTs（the canonical ENSO mode） and positively correlated with the negative phase of the North Atlantic SST tripole（NAT）. During the post-2000 period（2000-14）, the SASM is negatively correlated with central Pacific SSTs and positively correlated with the positive phase of the NAT pattern. The associated Pacific SSTs change from the eastern to central region, leading to the rising（subsiding） branch of the Walker circulation moving westwards to the Maritime Continent in the latter period, which can impact the interannual variability of the SASM through modulating the wind field in the troposphere. In addition to Pacific SSTs, the NAT SSTs can propagate energy from the North Atlantic to the South Asian High（SAH） region through the wave activity flux, and then further impact the SASM via the *** the SASM is intimately related with precipitation over the Asian region, we briefly discuss the features of the precipitation patterns associated with the SASM during the two periods. The westward shifting Walker circulation leads to the shrinking and weakened anomalous westerlies of the SASM in the lower level, inducing the Maritime Continent rainfall location to move westwards and more moisture to arrive in southern China from the Pacific Ocean in the latter period.
