摘要

在过去的几十年里,人们从理论上和实验上对生物系统中的铁电性进行了预测。生物系统中铁电性的主张引起了混淆和方法上的争议。多年来,随着外加电场的变化,一个诱导极化的“循环”和随之而来的极化反转,促使许多研究人员声称在生物结构及其构建块中存在铁电性。其他观察者对生成数据所采用的方法持怀疑态度,并质疑所声称的铁电性的有效性,因为“环路”也可以从线性电容器中获得。在一篇标题有点半开玩笑的论文中,吉姆·斯科特(Jim Scott)指出,普通的香蕉皮可以表现出电荷的闭环,这种闭环与铌酸钡钠中的铁电迟滞环非常相似,因此可能被误解为铌酸钡钠中的铁电迟滞环,BNN将其解释为“香蕉”。在本文中,我们批判性地回顾了生物系统中的铁电性,并认为了解生物构建块的分子和晶体结构并在这些构建块上进行实验可能是揭示生物系统中铁电性的“真实”本质的前进方向。

Ferroelectricity in biological building blocks: Slipping on a banana peel?
Ferroelectricity in biological system has been anticipated both theoretically and experimentally over the past few decades. Claims of ferroelectricity in biological systems have given rise to confusion and methodological controversy. Over the years, a “loop” of induced polarization in response to a varying applied electrical field and a consequent polarization reversal has prompted many researchers to claim ferroelectricity in biological structures and their building blocks. Other observers were skeptical about the methodology adopted in generating the data and questioned the validity of the claimed ferroelectricity as such, “loop” can also be obtained from linear capacitors. In a paper with somewhat tongue-in-cheek title, Jim Scott showed that ordinary banana peels could exhibit closed loops of electrical charge which closely resemble and thus could be misinterpreted as ferroelectric hysteresis loops in barium sodium niobate, BNN paraphrasing it as “banana”. In this paper, we critically review ferroelectricity in biological system and argue that knowing the molecular and crystalline structure of biological building blocks and experimenting on such building blocks may be the way forward in revealing the “true” nature of ferroelectricity in biological systems.

期刊介绍: The Journal of Advanced Dielectrics is an international peer-reviewed journal for original contributions on the understanding and applications of dielectrics in modern electronic devices and systems. The journal seeks to provide an interdisciplinary forum for the rapid communication of novel research of high quality in, but not limited to, the following topics: Fundamentals of dielectrics (ab initio or first-principles calculations, density functional theory, phenomenological approaches). Polarization and related phenomena (spontaneous polarization, domain structure, polarization reversal). Dielectric relaxation (universal relaxation law, relaxor ferroelectrics, giant permittivity, flexoelectric effect). Ferroelectric materials and devices (single crystals and ceramics). Thin/thick films and devices (ferroelectric memory devices, capacitors). Piezoelectric materials and applications (lead-based piezo-ceramics and crystals, lead-free piezoelectrics). Pyroelectric materials and devices Multiferroics (single phase multiferroics, composite ferromagnetic ferroelectric materials). Electrooptic and photonic materials. Energy harvesting and storage materials (polymer, composite, super-capacitor). Phase transitions and structural characterizations. Microwave and milimeterwave dielectrics. Nanostructure, size effects and characterizations. Engineering dielectrics for high voltage applications (insulation, electrical breakdown). Modeling (microstructure evolution and microstructure-property relationships, multiscale modeling of dielectrics).
