An innovative partnership for the development of nanotechnology in a developing country

Posada E., Mojica D., Hatch Indisa, CO

Colombia is a developing Latin American country which is making various efforts to enhance its human talent and generate value and prosperity based in science and advanced technology. Medellín, a pioneer city in this sense, [...]

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 [...]

Sound Attenuating Performance of Nanofibre Materials

Beckermann G., Revolution Fibres, NZ

Filming from unmanned aerial vehicles (UAV’s) has gained significant market acceptance within industry for commercial applications, including cinematography and live broadcasts, and is gaining momentum within the civil market. The noise generated from UAV operations [...]

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 [...]

Adsorption of Crystal Violet Dye from Aqueous Solution on Palm Kernel Shell Activated Carbon – Magnesium Oxide Composites Particles

Adebayo G.B., Adegoke H.l, Adekola F.A., Omolade O.O, Abiodun A., University of Ilorin, NG

A composite of activated carbon prepared from palm kernel shells (PKSAC) and magnesium oxide (MgO) particles was synthesis through hydrothermal method in ratio 10:1. The Palm kernel was carbonized at 6000C for two hours, it [...]

Melt-mixed thermoplastic polymer/carbon nanotube composites for thermoelectric applications

Pötschke P., Krause B., Luo J., Leibniz Institute of Polymer Research Dresden (IPF), DE

Thermoelectric generators (TEG), which can convert waste heat directly into electricity, are one type of promising energy harvesting devices. The thermoelectric (TE) effect (also called Seebeck effect) describes an electrical potential (voltage ∆U) induced by [...]

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 [...]

Catalytic Oxidation of Volatile Organic Compounds

Padilla O., Gallego J., Santamaria A., University of Antioquia, CO

The volatile organic compounds (VOCs) include a set of hydrocarbons with high vapor pressure. VOCs are highly harmful to health and the environment [1]. Catalytic oxidizers are one of the rising alternatives for remove them [...]
