Design of an Electrically Written and Optically Read Non-volatile Memory Device Employing BiFeO3/Au Heterostructures with Strong Absorption Resonance

Exploiting new concepts for dense, fast, and nonvolatile random access memory with reduced energy consump- tion is a significant issue for information technology. Here we design an ＇electrically written and optically read＇ information storage device employing BiFeO3/A u heterostruetures with strong absorption resonance. The electro- optic effect is the basis for the device design, which arises from the strong absorption resonance in BiFeO3/Au heterostructures and the electrically tunable significant birefringence of the BiFeO3 film. We first construct a sim- ulation calculation of the BiFeO3/Au structure spectrum and identify absorption resonance and electro-optical modulation characteristics. Following a micro scale partition, the surface reflected light intensity of different polarization units is calculated. The results depend on electric polarization states of the BiFeO3 film, thus BiFeO3/Au heterostructures can essentially be designed as a type of electrically written and optically read infor- mation storage device by utilizing the scanning near-field optical microscopy technology based on the conductive silicon cantilever tip with nanofabricated aperture. This work will shed light on information storage technology.

A focus review on 3D printing of wearable energy storage devices

Three-dimensional(3D)printing has gained popularity in a variety of applications,particularly in the manufacture of wearable devices.Aided by the large degree of freedom in customizable fabrication,3D printing can cater towards the practical requirements of wearable devices in terms of light weight and flexibility.In particular,this focus review aims to cover the important aspect of wearable energy storage devices(WESDs),which is an essential component of most wearable devices.Herein,the topics discussed are the fundamentals of 3D printing inks used,the optimizing strategies in improving the mechanical and electrochemical properties of wearable devices and the recent developments and challenges of wearable electrochemical systems such as batteries and supercapacitors.It can be expected that,with the development of 3D printing technology,realization of the full potential of WESDs and seamless integration into smart devices also needs further in-depth investigations.

Security Threats to Business Information Systems Using NFC Read/Write Mode

Radio Frequency IDentification(RFID)and related technologies such as Near Field Communication(NFC)are becoming essential in industrial contexts thanks to their ability to perform contactless data exchange,either device-to-device or tag-to-device.One of the three main operation modes of NFC,called read/write mode,makes use of the latter type of interaction.It is extensively used in business information systems that make use of NFC tags to provide the end-user with augmented information in one of several available NFC data exchange formats,such as plain text,simple URLs or enriched URLs.Using a wide variety of physical form factors,NFC-compatible tags(wireless transponders)are currently available in many locations with applications going from smart posters,contactless tokens,tap-and-go payments or transport ticketing to automated device configuration,patient identification at hospitals or inventory management within supply chains.Most of these applications handle sensitive processes or data.This paper proposes a complete security threat model for the read/write operation mode of NFC used in Next Generation Industrial IoT(Nx-IIoT)contexts.This model,based on a wellknown methodology,STRIDE,allows developers and users to identify NFC applications vulnerabilities or weaknesses,analyze potential threats,propose risk management strategies,and design mitigation mechanisms to mention only some significant examples.

On the Application of Reading-to-Write Approach to English Writing Teaching in Senior Middle School

As one of the four basic skills of language teaching and an aspect of communicative competence,writing seems to be the weakest one among senior school students in China.Most of teachers have had such experiences that although we spend a lot of time marking on the students'writing,but only to find the corrections and comments ignored.The students pay little attention to responses and regard revision of their writing as a punishment.Starting from the perspectives of modern linguistic theory,the pressing demands of the new curriculum,and the practical needs of student development,the study analyses the prevalent misconceptions about writing.The author proposes an assumption of integrating the teaching materials with Reading-to-Write Approach in the senior school writing teaching.To examine the validity of the Approach,about one-year action research is carried out in an ordinary high school,adopting the methodology of literature survey,questionnaire survey,interview,testing and so on.The results of the experiment showed that the approach had a more positive impact on students'writing attitudes and habits than traditional teaching methods.This approach helped them much more in word usage,longer sentences,content,and text structure or development.Besides,the students'compe?tence of interaction and cooperation were enhanced,Therefore,the approach in writing teaching is effective.

基于整本书阅读的辩论训练与过程评价对高中生议论文写作的影响

提升学生的议论文写作水平是高中语文教学的重点和难点。但仅仅依靠课文学习讲解或泛泛地开展整本书阅读,并不能有效提升高中生的议论文写作水平。为探索提升高中生议论文写作水平的有效方法,在一所普通高中实施一项为期14天的基于整本书阅读的辩论训练与过程评价实验。实验对象为该校高一和高二年级的45名学生志愿者。他们被分成6个小组,每组匹配1名导师,阅读材料包括《巴黎圣母院》《围城》《边城》等14本文学名著。实验结果表明,在整本书阅读后增加辩论训练和过程评价,可以非常显著地提升学生的议论文写作水平,具体表现在文章立意、论据选择和论证过程等方面。这些进步可能得益于本实验提升了学生的信息提取、事实判断、整合诠释、逻辑推理,以及分析性思维和批判性思维等高阶思维水平。因此,要提升高中生的议论文写作水平,将整本书阅读与辩论训练和过程评价整合在一起是一个值得尝试的办法。

喷头流道结构参数对高黏度含能材料直写成型3D打印挤出过程稳定性影响

为了研究直写成型技术(DIW)中挤出系统的喷头流道结构参数(锥角角度、出口直径、成型段长度)对含能材料挤出过程的流体流动影响,研究建立了基于Polyfow Extrusion模块的高黏度含能材料挤出模型,并采用直写成型3D打印工况的挤出实验对其进行了验证。研究通过所建立的模型分析了锥角角度范围90°~130°,出口直径0.75~2 mm以及成型段长度5~20 mm对高黏度含能材料挤出过程的影响。结果表明:采用Polyflow Extrusion模块可以较准确地模拟复合含能材料的流动行为,同时发现锥角为100°、喷头出口直径为1.5~1.75 mm时挤出成型过程相对稳定、挤出膨胀较小,且成型段的增长会在增大所需入口压强的同时减小出口膨胀效应。
