Versatile liquid manipulating surfaces combining patternable and controllable wettability have recently motivated considerable attention owing to their significant advantages in droplet-solid impacting behaviors,microdroplet self-removal,and liquid–liquid interface reaction applications.However,developing a facile and efficient method to fabricate these versatile surfaces remains an enormous challenge.In this paper,a strategy for the fabrication of liquid manipulating surfaces with patternable and controllable wettability on Polyimide(PI)film based on femtosecond laser thermal accumulation engineering is proposed.Because of its controllable micro-/nanostructures and chemical composition through adjusting the local thermal accumulation,the wettability of PI film can be tuned from superhydrophilicity(~3.6°)to superhydrophobicity(~151.6°).Furthermore,three diverse surfaces with patternable and heterogeneous wettability were constructed and various applications were successfully realized,including water transport,droplet arrays,and liquid wells.This work may provide a facile strategy for achieving patternable and controllable wettability efficiently and developing multifunctional liquid steering surfaces.

Uridine diphosphate-glucosyltransferases(UGTs)maintain abscisic acid(ABA)homeostasis in Arabidopsis thaliana by converting ABA to abscisic acid-glucose ester(ABA-GE).UGT71C5 plays an important role in the generation of ABA-GE.Abscisic acid receptors are crucial upstream components of the ABA signaling pathway,but how UGTs and ABA receptors function together to modulate ABA levels is unknown.here,we demonstrated that the ABA receptors RCAR12/13 and UGT71 C5 maintain ABA homeostasis in Arabidopsis following rehydration under drought stress.Biochemical analyses show that UGT71C5 directly interacted with RCAR8/12/13 in yeast cells,and the interactions between UGT-71C5 and RCAR12/13 were enhanced by ABA treatment.Enzyme activity analysis showed that ABA-GE contents were significantly elevated in the presence of RCAR12 or RCAR13,suggesting that these ABA receptors enhance the activity of UGT71C5.Determination of the content of ABA and ABA-GE in Arabidopsis following rehydration under drought stress revealed that ABA-GE contents were significantly higher in Arabidopsis plants overexpressing RCAR12 and RCAR13 than in nontransformed plants and plants overexpressing RCAR11 following rehydration under drought stress.These observations suggest that RCAR12 and RCAR13 enhance the activity of UGT71C5 to glycosylate excess ABA into ABA-GE following rehydration under drought stress,representing a rapid mechanism for regulating plant growth and development.

中华传统文化中的“文德”,最初指“君王之道”,是帝王内圣外王的政治手段,对外用于扩张领土,对内作为道德要求统治臣子。在长期的政治生活正向演绎中,“文德”的内涵发生外延,在文论中作为专门概念继续演化。进入文学批评领域后,“文德”成为对“文人之德”与“文章之德”的最高要求,经学者的推动演变为“文德说”,即中国文学思想史上批评伦理的重要理论。

Histone H2 A methylation at Gln104(H2AQ104Me) is a new type of histone post-translational modification(PTM) discovered recently. This modification has been found to have significant influence on gene transcription. However, the structural and functional consequence of glutamine methylation on nucleosome remains to be further elucidated. Obtaining of histones with site-specific methylation at glutamine residues might facilitate the studies towards a better understanding of this new PTM. In the present work, total chemical synthesis of H2AQ104 Me was carried out through use of the hydrazide-based native chemical ligation. Synthetic histone H2AQ104 Me could be successfully incorporated into nucleosomes in vitro and showed a negative influence on the nucleosome stability.

孟浩然的山水田园诗中隐藏着大量的时间意识的诗歌,既有通过季节变换感悟时间的诗,也有因为岁时体悟时间的诗。这些时间意识的诗是诗人人生历程的回望,充满着对人生理想难以实现的焦虑。主要原因是孟浩然遭遇了现实与心灵的双重困境,也正是这种困境,造成了他在仕隐中摇摆不定的人生形象。

Over the past few decades,extensive scientific has been dedicated to polymer synthesis employing renewable resources.In this study,we devised and synthesized multifunctional polyeugenol-based nanoparticles,exhibiting remarkable antioxidant and antibacterial properties.The grafting of eugenol onto the nanoparticle surface was achieved via a thiol-ene chemical reaction with a grafting rate of 3.5%.To comprehend the properties of the synthesized nanoparticles,we employed Fourier transform infrared spectroscopy,X-ray photoelectron spectroscopy and pyrolysis-gas chromatography mass spectrometry.Subsequent scanning electron microscopic and transmission electron microscopic analyses revealed the presence of a crosslinked structure within the polyeugenol-based nanoparticles,as well as a heteroge-neous microsphere structure on the surface.Due to the inherent crosslinking structure,the polyeugenol-based nanoparticles demonstrated robust the resistance to solvents,as ascertained through thermog-ravimetric analysis and solvent resistance tests.Notably,nitrogen adsorption/desorption studies confirmed the adsorption capacity of the polyeugenol-based nanoparticles,rendering them potentially suitable for drug transport applications.Moreover,the assays for assessing cytocompatibility and reactive oxygen species scavenging activities demonstrated better performance of the eugenol-based nano-particles compared to eugenol.Furthermore,the polyeugenol-based nanoparticles exhibited certain bactericidal activities against Escherichia coli,Staphylococcus aureus,and Fusobacterium nucleatum.Consequently,these observations indicated the nontoxic nature and expansive application prospects of the polyeugenol-based nanoparticles in the domains of medicine and food preservation.This work presented a pioneering concept for the development of antioxidant and antibacterial multifunctional polymer materials derived from eugenol.

基于交替方向乘子法(ADMM)的改进惩罚函数LDPC译码算法能够提升译码性能,但其所需优化参数过多且性能提升有限。针对该问题,将该算法与其它带有惩罚函数的译码算法比较后发现,两者的不同之处仅在于译码算法中变量节点的更新规则不同。因此,该文通过构造一种新的变量节点的更新方法去减少优化参数数目并提升译码性能。实验仿真表明,相较于原有算法,该文所提算法有效减少了所需优化的参数数目,此外,所提算法的平均迭代次数更少且能实现约0.1 dB的性能提升。
