The bucky aerogel (BAG) is a 3D,interconnected, carbon nanotube based material that is capable of efficiently separating oil from water. Our facile and scalable top down approach allows a strong control of the porosity. BAG exhibits superhydrophobicity and oleophilicity, which when combined with its capillary action allows selective adsorption of various organic solvents up to 20 times its weight.
- Low-Density High-Strength Bulk Metallic Glasses and Their Composites: A Review
Jian-Zhong Jiang, Douglas Hofmann, David John Jarvis and Hans-J. Fecht
Article first published online: 19 NOV 2014 | DOI: 10.1002/adem.201400252
This review gives an overview of recent accomplishments in the field of lightweight bulk metallic glasses/composites and their potential engineering and space applications. We mainly focus on four systems, namely, Al-, Mg-, Ca-, and Ti-based metallic glasses. Glass forming ability, mechanical properties, thermal stability, and corrosion resistance of the four metallic glass systems and their composites are presented.
- On the Super-Elastic and Phase Transformation of a Novel Ni-Rich/NiTiCu Bi-Layer Thin Film

A novel bi-layer Ni-rich/Ti-rich thin film is deposited and crystallized. The bi-layer exhibits a two-step transformation B2 R B19’ with narrow thermal hysteresis. It presents a pseudo elastic effect and partial permanent strain because of composite structure. Its modulus and hardness values are between martensite and austenite phases.
- Morphology Evolution of ZnO Submicroparticles Induced by Laser Irradiation and Their Enhanced Tribology Properties by Compositing with Al2O3 Nanoparticles

A laser-stimulated surface tension energy release strategy is reported to grow metal oxide spherical particles using ZnO as example. The ZnO submicrospheres exhibit clear morphology-dependent friction reduction property but no anti-wear effect. However, the integrated application of ZnO submicrospheres and Al2O3 nanoparticles can improve both the friction-reduction and anti-wear properties.
- Load Sharing Phenomena in Nanoscale Cu/Nb Multilayers
Mikhail N. Polyakov, Jochen Lohmiller, Patric A. Gruber and Andrea M. Hodge
Article first published online: 3 NOV 2014 | DOI: 10.1002/adem.201400368
By use of X-ray diffraction, the load-bearing contributions of nanometer-thick Cu and Nb layers in Cu/Nb multilayer composites are isolated. The Cu bears higher stresses at failure and the Nb bears lower stresses at failure with decreasing Cu layer thickness. The Cu and Nb layers appear to have independent deformation mechanisms.
