Researches of visible light photo-sensitized porphyrin-TiO2 photocatalyst and its related self-cleaning effects

Min K., Manivannan R., Lee S-G, Son Y., Chungnam National University, KR

The sensitization of TiO2 with a wide variety of inorganic and organic dyes for light harvesting has been investigated over the last 2 decades for the development of efficient energy harvesting. Porphyrins, as important biomolecules, [...]

Effects of Mn doping on Grain and Grain Boundary Properties of Bi2WO6-based ZnO Varistor using Dielectric Functions for Surge Protection Application

Hong Y.W., Ha M.J., Paik J.H., Cho J-H., Jeong Y.H., Yun J.S., Park W.I., Korea Institute of Ceramic Engineering & Technology, KR

Polycrystalline ZnO has been applied to various electrical and optical applications such as gas sensors, piezoelectric transducers, phosphors, transparent conducting films, and varistors. To control the figure of merits of these devices it is essential [...]

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, [...]

Nanoclay-reinforced Nanocellulose Composite Films with Improved Heat resistance, Gas Barrier Performance, and Mechanical properties

Ryu J.H., Jeong Y.G., Chungnam National University, KR

Since nanocellulose (NC) has excellent strength, modulus, lightness, and thermal stability, it has been widely utilized for composites, electronics, sensors, papers, coatings, films, aerogels, health care, additives, etc. In this study, to attain NC films [...]

Modification of Cellulose Nanocrystals for Compostable Food-Packaging

Bosnick K., Benhalima A., Chapleau N., Champagne M., National Research Council Canada, CA

To support the sustainability of the food packaging industry, a move from petroleum-derived packaging products to renewable-derived ones is needed. In addition, a complete compostability of the packing is desirable for reducing waste at the [...]

A Study of Cutting Temperatures in Turning Glass-Fiber-Reinforced -Plastic (GFRP) Composites with nose radius worn tools

Chang C-S, National Ilan University, TW

Abstract: Nine kinds of chamfered main cutting edge carbide tools were used in turning of glass-fiber-reinforced plastics (GFRP) materials to study the temperature of tip's surface and the cutting forces. Force data from these tests [...]

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, [...]

Self-Activated Morphing Carbon Fiber Composites Via Cyclic Internal Stresses

Casalotti A., Lanzara G., University of Roma Tre, IT

An innovative concept to exploit self-activated morphing composite materials is presented and demonstrated experimentally. In this design, shape changes of a carbon fiber composite are achieved by combining two key ingredients: fibers orientation and temperature-sensitive [...]
