<div><div><div><p>One of the fascinating properties of metal-semiconductor Schottky-barriers, which has been observed for some material combinations, is memristive behavior. Memristors are smart, since they can reversibly switch between a low resistance state and a high resistance state. The devices offer a great potential for advanced computing and data storage, including neuromorphic networks and resistive random-access memory. However, as for many other cases, the presence of a real interface (metal - metal oxide) has numerous disadvantages. The realization of interface-free, respectively Schottky-barrier free memristors is highly desirable. The aim of the current paper is the generation of nanowire arrays with each nanorod possessing the same crystal phase (Rutile) and segments only differing in composition. The electric conductivity is realized by segments made of highly-doped antimony tin oxide (ATO) transitioning into pure tin oxide (TO). Complex nanoarchitectures are presented, which include ATO-TO, ATO-TO-ATO nanowires either with a stepwise distribution of antimony or as a graded functional material. The electrical characterization of the materials reveals that the introduction of memristive properties in such structures is possible. The special features observed in voltage-current (IV) curves are correlated to the behavior of mobile oxygen vacancies (VO..) at different values of applied electrical potential.</p></div></div></div>

Barrier Free

The problem of the discrimination of people with disabilities remains being an urgent social problem. Misunderstanding of the meaning of this problem by others results in a situation when invalid’s level of life cannot be equal to a healthy person’s level of life. This article raises the issue of ableism in order to explore the idea of barrier-free environment integration. The results of a social survey are demonstrating a good level of respondent’s awareness concerning this problem and their will to participate in a discussion and taking of measures for the integration of a barrier-free environment with the intention to raise the invalid’s level of life.

Barrier Free

Cooking themselves is very important and difficult for elderly and disabled people in daily life. This paper presents a cooking robot for those people who are confined to wheelchairs. The robot can automatically load ingredients, cook Chinese dishes, take cooked foods out, deliver dishes to the table, self-clean, collect used ingredient box components, and so on. Its structure and interface is designed based on the barrier-free design principles. Elderly and disabled people can only click one button in the friendly Graphic User Interface of a Personal Digital Assistant (PDA) to launch the cooking processes, and several classic Chinese dishes would be placed in front of them one after another within few minutes. Experiments show that the robot can meet their special needs, and the involved aid activities are easy and effective for elderly and disabled people.

Barrier Free

It’s the library’s duty to offer barrier-free service for the disabled. And applied-information technology is applied into the barrier-free service, which may be found helpful to promote the disabled readers’ initiatives and help them seek for information conveniently in library. There are some measures university library can take to offer barrier-free service with applied-information technology such as opening more free computer-training classes for disabled readers to improve their information skills, offering aural OPAC service, posting the copies of library resources by E-mail and providing assistive technology and equipment related to information service. In addition to these measures, some activities like enriching the spiritual and cultural life of the disabled readers and increasing the communication between able-bodied people and the disabled.
