Nanoporous thin film fabrication via magnetron sputtering and O2 plasma ashing process

Han S.H., Jang S.W., Hwang S., Hwang S.H., Hwang S., Hwang S.H., Korea Institute of Science and Technology, KR

We report a new method of fabricating nanoporous catalytic thin films. In the first step, metal–carbon thin films were prepared by reactive magnetron sputtering, using various metallic targets (Au, Ag, Pt, Cu, Ni, Ti) as [...]

Azide-alkyne cycloaddition by recyclable heterogeneous Cu catalysts on reverse phase silica gel

Jang Y., Kim H., Lim M., Rhee H., Hanyang University, KR

Previously, we developed heterogeneous Pd catalysts immobilized onto functionalized reverse phase silica gel. These catalysts were applied to Suzuki cross coupling reactions and the hydrogenation reactions in water with good results. In this study, Cu [...]

Pd nanoparticles immobilized onto polymer-inorganic hybrid support: Synthesis, characterization and catalytic activity on Suzuki-Miyaura coupling reactions in water

Lim M., Kim H., Jang Y., Rhee H., Hanyang University, KR

The development of heterogeneous metal catalysts supported on a solid support has attracted attention. This catalyst system has the advantages of ease of catalyst separation and reusability, and has higher reactivity due to the larger [...]

Partially Poisoned Pd Nanoparticles for Selective Hydrogenation and/or Isomerization of Olefins

Shon Y-S, California State University Long Beach, US

Selective hydrogenation and/or isomerization of olefins are important processes in both chemical and pharmaceutical industries. Our group previously reported that the thiosulfate protocol using sodium S-alkylthiosulfates instead of alkanethiols could generate catalytically active Pd nanoparticles [...]

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 [...]
