Rethinking seismic protection in areas of substandard construction

McGlynn C., Zhu C., Rowan University, US

Populations continue to increase in areas that have high levels of seismic activity, especially in urban communities along the western United States, Japan, China, South America, and India. By 2030, approximately 60 percent of the [...]

Magnetic Heterostructures with Tunable Spin-dependent Transport Properties

Sahakyan A.S., Poghosyan A.V., Movsesyan R.M., Kocharian A.N., California State University Los Angeles, US

The transport properties in magnetic films consisting of alternating magnetic nanolayers separated by nonmagnetic quantum wells are studied for a definite finite number of (N) magnetic barriers consisting of two branches of ferromagnetically ordered structures. [...]

Modeling Failure in Fiber-Reinforced Composite Tubes using TRUE Multiscale technology

Souza F, Castro L, Neves K, Lima L, Cornwell H, Multi, US

Finite element analysis has become increasingly important for mechanical design and the development of new advanced materials. Being able to predict structural performance accurately and efficiently can circumvent the extensive time and cost of repetitive [...]

Lightweight, High Performance Polymer Composites for Modern Engineering Applications

Lynch-Branzoi J., Rutgers University, US

Modern engineering applications require a new class of materials that offer high performance and are also lightweight. Graphene-polymer matrix composites are promising structural materials due to the exceptional properties of graphene. Here, we demonstrate a [...]

Mesoporous Alumina Affinities for Metals as a Function of pH

Hepburn R., Fujimi Corporation, US

One important application for mesoporous alumina is as the adsorbent for retaining Molybdenum-99m in the Molybdenum/Technetium generators used for medical imaging throughout the world. In 2016, Fujimi created a novel mesoporous alumina material that could [...]

Electrical characteristics of individual FeNiCo-Au core-shell nanowires integrated into microelectrodes on plastic substrate

Beheshti M., Geng X., Choi J., Podlaha-Murphy E., Park S., Louisiana State University, US

Synthesis, characterization and integration of single metallic nanowires with enhanced electrical and mechanical properties into plastic substrate is a vital task for the development of transparent/flexible electronics as well as nanosensors. Among the metallic nanowires, [...]

Facts and Myths about Cellulose Nanofibrils (CNF): What to Expect and What to Not

Tajvidi M., University of Maine, US

Cellulose nanofibrils (CNF) are perhaps the only type of cellulose nanomaterials that have the potential for both large volume production and large volume applications in near future. Much research has been conducted on the production, [...]

Interfacial nanostructure dictates macro-structural properties of carbon-carbon composites

Singh M., Vander Wal R., Pennsylvania State University, US

Carbon-carbon composites, originally developed for aerospace applications, are materials that consist of a carbonaceous matrix with an embedded carbon filler providing the required reinforcement for thermal and mechanical stability. An important aspect of composites is [...]

Recoverable Lightweight Nanocomposites

Huckleby A.B., Li J., Shahrizan Jamal M., Zhang M., Florida State University, US

The demand for lightweight and strong structures continues to rise especially for weight critical applications such as aerospace and automotive. It is also desired that the materials can recover after being deformed. In this work, [...]

Advanced Film Thermal Protectors for Electronic Devices

Wang Y., UCI, US

This advanced thermal protector is based on the patent (U.C. Case No. 2012-130), which provides one-way heat flow function, i.e. enabling heat dissipation from the electronic devices, while preventing outside heat from thermally damaging the [...]
