Study on the behavior of semiflexible polymer translocating into spherical cavity through the nanopore(半柔性大分子链穿越微孔行为的研究)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2016
采用动态蒙特卡罗模拟方法,模拟半柔性大分子链在电场作用下穿越纳米孔道进入球腔的输运过程.主要研究电场强度及半柔性大分子链的刚性强度对穿孔过程的影响.发现:平均穿孔时间τ随电场强度的增大而减小,τ与链的长度N满足标度关系τ〜Nα,并且电场强度E和弯曲能b对标度指数有显著影响.研究结果表明,当电场强度为中等时,刚性弱和刚性强的大分子的穿孔过程是完全不同的.研究半柔性大分子链穿越微孔的行为,有助于更深入认识生物大分子在生命体内的输运过程.

Preliminary Exploration of Surface-Plasmon Gain Medium and the Resonance of TE-Polarized Light on Metal Grating Surface [PDF]

open access: yes, 2015
表面等离激元(SurfacePlasmon,SP)是金属-介质界面处的自由电子在高频电磁波(如光波)耦合作用下集体谐振的一种电子密度波。它具有强烈的局域电磁场增强、突破衍射极限、亚波长局域化等一系列出色的特点,引起了研究者对它的高度关注。但是由于金属本征吸收的存在和激发方式的限制,阻碍了了表面等离激元器件的发展。针对于此,本文主要对以下两个方面进行了一些探索和研究。 首先,我们通过溶胶凝胶方法探索制备掺铒二氧化硅薄膜的工艺,以期将其作为补偿等离激元器件损耗的一种增益材料。针对加入不同量比的异丙醇(IPA)

Bifunctional Competitive Structure of Biomass Carbon‐Derived Metacomposites for Tunable ε′‐Near‐Zero and ε′‐Negative Responses

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Regulating negative parameters of metacomposites is mainly limited by their unclear mechanisms, which affects their practical applications in new sensing, communication, electromagnetic (EM) protection and other fields. This work proposes a dual‐functional competitive design strategy based on the waste corncob‐derived carbon/polyaniline ...
